Kev nkag siab txog lub ntsiab lus dav dav yog ncaj nraim. Qhov tob tiag tiag, qhov uas cais cov neeg yuav khoom paub los ntawm txhua tus neeg, nyob rau hauv cov ntsiab lus ntawm txhua qhov chaw nres tsheb ua haujlwm, cov cuab yeej siv tau dab tsi, thiab qhov twg cov lus qhia txog kev lag luam hauv koj qhov kev nyiam. Cov ntsiab lus no ua rau txhua qhov kev txiav txim siab los ntawm kev xaiv cov khoom siv rau cov khoom tsim nyog.

Yuav Ua Li Cas Progressive Die Stamping Txheej Txheem Ua Haujlwm Hauv Chaw Nres Tsheb

Lub stamping xovxwm ua haujlwm li cas thaum nws khiav qhov kev vam meej? Los ntawm sab nraud, koj pom ib lub coil ntawm cov hlau pub rau hauv thiab ua tiav cov khoom xa tuaj. Tab sis nyob rau hauv cov cuab yeej ntawd, ua tib zoo choreographed ib theem zuj zus ntawm kev khiav hauj lwm transforms tiaj tiaj mus rau hauv ib tugpeb-seem ib feemnyob rau hauv ib feem ntawm ib tug thib ob. Nov yog qhov tshwm sim tiag tiag ntawm txhua theem ntawm cov txheej txheem tuag.

Coil Feeding thiab Sawb Progression

Txhua yam pib ntawm lub uncoiler, qhov twg ib yob ntawm cov ntawv hlau, qee zaum hnyav ntau txhiab phaus, yog mounted thiab npaj noj. Lub sawb hla dhau los ntawm ib qho kev ncaj uas tshem tawm cov curvature (hu ua coil set) imparted los ntawm kev raug mob ntawm ib tug spool. Yog tsis muaj cov kauj ruam no, cov khoom siv yuav hneev thiab buckle hauv qhov tuag, ua rau misfeeds thiab qhov tsis zoo.

Los ntawm lub straightener, ib tug servo feeder nce lub sawb mus rau hauv lub zog stamping xovxwm los ntawm ib tug meej nyob deb hu ua lub feed pitch. Lub suab no sib phim qhov sib nrug ntawm qhov chaw tuag, yog li txhua tus mob stroke tso cov khoom tshiab raws nraim qhov nws xav tau. Tab sis tus feeder ib leeg tsis lav qhov kev sib raug zoo. Txoj hauj lwm ntawd yog tus tsav tus pins: cov pins hardened mounted nyob rau hauv lub Upper tuag uas poob rau hauv pre- tho qhov nyob rau hauv lub sawb ua ntej txhua lub chaw nres tsheb ua nws txoj haujlwm. Cov kws tsav dav hlau kho qhov yuam kev me me, feem ntau tuav cov ntawv sau npe rau hauv 0.0005 txog 0.001 ntiv tes. Yog tsis muaj kev txhim kho kev tsav tsheb, kev kam rau siab drift accumulates chaw nres tsheb los ntawm chaw nres tsheb thiab cov nqi seem nce.

Piav qhia txog kev ua haujlwm hauv chaw nres tsheb

Txhua qhov chaw nres tsheb hauv qhov kev tuag zuj zus ua ib txoj haujlwm tshwj xeeb, thiab cov kab ke raug tsim kho kom txo cov khoom siv kev ntxhov siab thaum tuav txoj hlua khi. Ntawm no yog qhov kev txiav txim ntawm kev ua haujlwm nyob rau hauv cov txheej txheem stamping zuj zus:

1. Piercing- Punches nqis los ntawm txoj hlua los tsim qhov, qhov, thiab cov yam ntxwv sab hauv. Qhov no feem ntau tshwm sim ua ntej vim qhov xav tau kev tsav tsheb rau kev tso npe ntawm cov chaw nres tsheb tom ntej, thiab txiav cov yam ntxwv sab hauv thaum ntxov tsis txhob cuam tshuam rau lawv thaum tsim tom qab.
2. Ntshai- Cov khoom raug tshem tawm los ntawm cov npoo ntawm lub sawb txhawm rau txheeb xyuas cov txheej txheem sab nrauv ntawm ib feem lossis los tsim kev tshem tawm rau kev khoov tom ntej. Tsis zoo li kev tho, qhov kev sib tw qhib txoj hlua ciam teb, uas txhais tau hais tias cov engineers yuav tsum xyuas kom muaj cov khoom thauj khoom txaus los thauj cov khoom mus rau tom ntej.
3. Lancing- Kev ua haujlwm hybrid uas txiav thiab khoov hauv ib leeg. Lub lance tsim ib lub tab los yog louver los ntawm shearing raws ib feem ntawm ib kab thiab folding lub freed seem upward los yog downward. Nws yog qhov ua tau zoo vim tias nws tsim cov yam ntxwv yam tsis muaj kev sib cais tag nrho ntawm cov sawb.
4. tsim- Lub strip yog khoov rau hauv peb -dimensional geometry: lub ces kaum, raws, tav, los yog complex contours. Cov chaw tsim khoom siv cov punches thiab cov kab noj hniav tuag los thawb cov hlau mus rau hauv nws qhov profile kawg. Vim tias kev sib sau qhia txog kev ntxhov siab, nws tau ua tiav tom qab feem ntau cov haujlwm txiav kom tsis txhob cuam tshuam cov qhov ua ntej los yog cov npoo.
5. Npib- Hlau yog compressed nruab nrab ntawm lub tiaj tus los yog zoo li tus nto nyob rau hauv siab tonnage kom ua tau nruj heev dimension tolerances los yog tshwj xeeb nto finishes. Coining displaces cov khoom ntau dua li txiav nws, ua rau nws zoo tagnrho rau calibrating thickness, flattening localized cheeb tsam, los yog embossing zoo nthuav dav.
6. Ncua tseg- Qhov chaw nres tsheb zaum kawg cais qhov ua tiav ntawm cov khoom thauj. Lub blanking punch shear raws qhov seem perimeter, thiab cov khoom tiav lawm poob dawb. Lub sijhawm no, txhua qhov tshwj xeeb twb tau tsim thiab ntsuas, yog li cov khoom tau npaj rau kev tshuaj xyuas lossis kev ua haujlwm qis.

Tsis yog txhua qhov tuag siv tag nrho rau hom kev ua haujlwm, thiab qee qhov yuav tsum muaj chaw nres tsheb ntxiv xws li kev txiav, kos duab, lossis hauv -tapping tuag. Lub ntsiab lus tseem ceeb yog qhov chaw nres tsheb sib lawv liag yeej tsis arbitrary. Cov kws tsim qauv npaj txhua kauj ruam kom txiav cov quab yuam sib npaug, tsim cov yam ntxwv tsis cuam tshuam nrog kev nce qib, thiab cov khoom ntws tseem tuaj yeem kwv yees thoob plaws lub voj voog.

Scrap Management thiab Part Ejection

Txhua qhov kev tho, thais, thiab blanking ua haujlwm tsim cov khoom seem. Cov me me cutout pieces, hu ua slugs, yuav tsum tawm ntawm qhov tuag cia siab rau. Nyob rau hauv feem ntau kev tuag, slugs poob downward los ntawm clearance qhov nyob rau hauv lub tuag thaiv thiab qis khau, xa me nyuam rov rau hauv seem chutes los yog bins hauv qab xovxwm. Yog hais tias ib tug slug sticks mus rau ib tug punch thiab tau rub rov qab mus rau hauv lub tuag (ib tug tsis xws luag hu ua slug rub), nws yuav ua puas rau lwm yam los yog txawm tawg ib tug punch.

Cov cab cab nws tus kheej, tam sim no ib lub pob txha ntawm cov txuas hniav thiab cov khoom seem, tawm hauv qab ntawm qhov tuag thiab yog txiav rau hauv luv luv los yog qhov txhab rau ntawm cov khoom seem. Lub caij no, cov khoom tiav raug tshem tawm los ntawm ib qho ntawm ntau txoj hauv kev: lub ntiajteb txawj nqus poob los ntawm qhov qhib tuag, cua blasts uas thawb cov khoom mus rau lub conveyor, lossis cov neeg kho tshuab kickers uas coj lawv mus rau hauv cov thawv ntim khoom.

Txhim khu kev tshem tawm cov khib nyiab tsis yog ib qho me me. Ntawm cov xovxwm ceev ntawm 200 mus rau 1,000 strokes ib feeb, txawm tias ib qho slug daig tuaj yeem nres ntau lawm thiab yuav tsum tau tshem tawm tuag rau kev tshem tawm. Tias yog vim li cas cov neeg tsim kev paub txog kev tuag tau npaj ncaj, tsis muaj kev cuam tshuam txoj hauv kev thiab suav nrog slug tuav cov yam ntxwv zoo li ejector pins lossis textured tuag qhib thaum pib tsim theem.

Nrog rau cov txheej txheem ntawm lub cev kom meej, cov lus nug tom ntej yog qhov tseeb hauv qhov cuab yeej no, cov khoom tshwj xeeb uas ua rau txhua qhov chaw nres tsheb ua haujlwm, hnav lub sijhawm, thiab thaum kawg txiav txim siab ntev npaum li cas tus neeg tuag ua ntej yuav tsum tau txais kev pabcuam.

Anatomy ntawm Progressive Tuag thiab Nws Cov Khoom Tseem Ceeb

Thaum koj nqis peev hauv cov cuab yeej ua tiav tuag, koj tsis tau yuav ib qho thaiv ntawm cov hlau tawv tawv. Koj tab tom yuav ib qho kev sib dhos ntawm kaum ob ntawm cov khoom, txhua tus muaj lub luag haujlwm tshwj xeeb, txhua yam yuav tsum hnav, thiab txhua qhov hloov tau thaum nws mus txog qhov kawg ntawm lub neej. Kev nkag siab txog dab tsi nyob hauv lub cuab yeej ua rau koj pom qhov pom tseeb ntawm koj cov nyiaj mus rau qhov twg, vim li cas lub sij hawm ua cov hmoov lead yog dab tsi, thiab dab tsi ua rau cov nqi kho mob hauv txoj kev.

Die Set Foundation thiab Cov Txheej Txheem Txheej Txheem

Txhua qhov kev vam meej tuag yog tsim los ntawm cov txheej txheem tuag: ib khub ntawm daim hlau tuab hu ua khau sab sauv thiab khau qis. Sab saum toj khau bolts rau xovxwm ram; cov khau qis clamps rau lub txaj xovxwm. Ua ke, lawv tsim cov pob txha pob txha uas tuav txhua lwm yam hauv kev sib dhos.

Kev sib txuas ntawm ob lub khau yog cov lus qhia thiab cov lus qhia bushings. Cov pins tawv thiab lub tes tsho no ua kom lub sab sauv thiab sab qis sib ntsib nyob rau hauv tib txoj hauj lwm ntawm txhua qhov mob stroke. Cov lus qhia tus pin kam rau ua haujlwm nyob rau hauv 0.0001 ntiv tes, nruj txaus kom tswj tau cov kev tshem tawm txawm tias rov qab siab dua -tonnage cuam tshuam ntawm qhov nrawm. Pob-cov kabmob qhia pins tau dhau los ua tus qauv kev lag luam vim tias lawv tso cai rau kev sib cais ntawm cov tuag halves thiab txo qis asymmetric hnav thaum lub sijhawm.

Cov pob taws pob taws, mounted nyob ze ntawm cov ces kaum ntawm cov txheej txheem tuag, nqus lateral zog generated thaum txiav thiab sib sau. Yog tsis muaj lawv, sab loads yuav hloov mus rau sab sauv ib nrab txheeb ze rau qis, ua rau tsis sib xws punch hnav thiab seem drift nyob rau hauv tiav qhov chaw.

Mounted rau sab saum toj khau, koj yuav pom cov ntawv xuas nrig thiab cov punch retainers uas tuav txiav thiab ua cov punches nyob rau hauv qhov tseeb. Rov qab daim hlau zaum tom qab cov punch retainers kom faib cov kev cuam tshuam rau hauv ib cheeb tsam dav, tiv thaiv cov punches los ntawm kev tsav tsheb rov qab rau hauv cov khoom khau softer nyob rau hauv rov qab caij tsheb kauj vab.

Cov Ntsiab Cai Ua Haujlwm Uas Tswj Txoj Cai

Cov khoom sib xyaw ua ke kom cov tuag sib dhos. Tab sis ib pawg thib ob ntawm cov khoom tswj cov hlau sawb nws tus kheej, ua kom nws nyob tiaj tus, nyob twj ywm hauv nruab nrab, thiab sau npe kom raug ntawm txhua qhov chaw nres tsheb.

strippersyog lub caij nplooj ntoos hlav-loaded daim hlau uas nias rau ntawm cov khoom raws li lub Upper tuag descends. Lawv ua haujlwm ob lub hom phiaj: tuav lub sawb tiaj tus tiv thaiv qhov chaw tuag qis thaum txiav thiab tsim, thiab stripping cov khoom tawm ntawm cov punches thaum lub xovxwm qhib. Yog tsis muaj lub zog stripper txaus, lub sawb tuaj yeem nqa nrog cov punches, deform, los yog misfeed ntawm tus mob stroke tom ntej.

Phau ntawv qhiayog cov channel precision machined rau hauv qis tuag uas ua kom cov sawb sib dhos tom qab. Lawv tiv thaiv cov khoom los ntawm drifting sab mus rau sab raws li nws nce mus, uas yuav pov tawm txhua qhov chaw nyob ze ntawm lub strip edge.

Cov kws tsav dav hlauyog cov pins tawv tawv uas nkag mus ua ntej - tho qhov hauv lub strip ua ntej txhua qhov chaw nres tsheb ua haujlwm. Lawv kho cov khoom seem uas tsis raug thiab xauv lub sawb mus rau qhov tseeb. Pilot clearance rau lub qhov yog feem ntau 0.0005 mus rau 0.001 nti, thiab pilot ntev yuav tsum tau xam kom tus pin nkag mus rau hauv lub sawb ua ntej lwm yam punches koom, tab sis tsis khi los yog rub cov khoom upwards thaum lub tuag qhib.

Liftersyog lub caij nplooj ntoos hlav- cov khoom siv thauj khoom uas tsa lub strip tawm ntawm qhov chaw tuag qis ntawm cov xovxwm strokes. Qhov kev tshem tawm no tso cai rau lub feeder ua ntej cov khoom siv mus rau qhov chaw tom ntej yam tsis muaj kev rub hla kev sib sau los yog qhov chaw tuag. Stamping tuag lifters yuav tsum tau teem sijhawm ua tib zoo nrog cov txheej txheem pub: cov khoom noj yob tseem qhib kom txog thaum cov lifters mus txog tag nrho cov kev mus ncig, ces kaw ua ntej cov lus qhia tsav tawm ntawm lub sawb. Misjudging no lub sij hawm qhov rais yog ib qho ntawm feem ntau ua rau kev loj hlob poob nyob rau hauv ntau lawm.

Cov ntsiab lus no ua haujlwm raws li qhov system. Cov lus qhia muab txoj hlua khi rau tom qab, cov neeg nqa nqa nqa nws rau kev pub mis, tus feeder nce nws ib lub suab, thiab cov kws tsav dav hlau xauv nws mus rau hauv kev sau npe zaum kawg ua ntej cov strippers clamp nws tiaj tus rau kev ua haujlwm tom ntej. Tshem tawm ib qho ntawm cov saw hlau ntawd thiab rov ua dua tshiab tawg.

Hnav Cheebtsam thiab Serviceability

Suab zoo li ntau yam khoom siv los tswj? Nws yog, tab sis niaj hnub stamping tuag yog tsim los rau modularity. Cov khoom uas hnav ceev tshaj plaws, xuas nrig ntaus, khawm tuag, tsav tsheb, thiab lub caij nplooj ntoos hlav, yog tsim los ua cov khoom siv hloov tau ntau dua li qhov tseem ceeb ntawm cov khoom thaiv. Thaum lub punch dulls lossis chips, tus kws tshaj lij tuaj yeem rub qhov ntxig ib leeg thiab hloov nws yam tsis muaj kev cuam tshuam tag nrho cov cuab yeej.

Kev xaiv cov khoom siv rau cov ntxig no nyob ntawm qhov ntim ntau lawm thiab cov khoom raug stamped:

• Cov cuab yeej steel (A2, D2, M2)- Zoo sib npaug ntawm toughness thiab hnav tsis kam; txheem kev xaiv rau feem ntau zuj zus tuag khiav me me hlau los yog txhuas
• Carbide inserts- Hnyav hnyav hnyav heev tab sis nkig ntau dua; siv rau siab -kev ceev ntau lawm, abrasive cov ntaub ntawv xws li stainless hlau, los yog daim ntaub ntawv thov ncua kev khiav ntawm sharpening
• Punch phaj thiab retainers- Tuav cov cuab yeej txiav hauv txoj hauj lwm; muaj nyob rau hauv pob-lock, xub pwg, thiab trumpet- lub taub hau style rau kev hloov pauv sai
• Tuag khawm- Poj niam txiav cov khoom ua ke nrog xuas nrig ntaus; offset me ntsis loj dua lub qhov ntswg punch (feem ntau 5-10% ntawm cov khoom tuab) los tsim cov clearance xav tau rau huv shearing
• Tuag springs (mechanical thiab nitrogen gas)- Muab lub zog stripping thiab tuav - cia siab; nitrogen gas springs muaj zog dua nyob rau hauv ib lub hnab ntawv me me
• Qhia pins thiab bushings- Alignment system; hloov thaum hnav dhau qhov tso cai kam rau ua
• Stamping tuag lifters thiab pilots- Sawb tswj cov ntsiab lus muaj kev sib cuag nrog cov khoom ua ntej; hloov ntawm lub sijhawm tiv thaiv

Qhov kev ua haujlwm modular no txhais tau hais tias qhov zoo-tsim kev tuag tuag tuaj yeem tsim ntau lab ntawm nws lub neej nrog kev hloov pauv raws sijhawm es tsis yog ua kom tiav. Cov tuag tau teeb tsa nws tus kheej, khau, taw qhia, thiab pob luj taws, tsis tshua xav tau hloov. Qhov kev nqis peev uas tsis tu ncua yog nyob rau hauv cov khoom siv thiab cov khoom siv uas siv cov brunt ntawm txhua lub voj voog xovxwm.

Kev xaiv ntawm carbide thiab cov cuab yeej steel inserts tsis yog kev txiav txim siab tus nqi xwb. Carbide siv sijhawm ntev dua ntawm kev sib tw ntse tab sis raug nqi ntau dua thiab ua rau muaj kev cuam tshuam ntau dua yog tias tuag tau ntsib kev tsis zoo lossis kev sib tsoo. Rau feem ntau cov stamping tuag khiav hauv qab 500,000 lub voj voog ntawm kev kho qhov rais, D2 cuab yeej steel muaj qhov zoo tshaj plaws sib npaug. Tshaj li qhov pib, lossis thaum stamping abrasive stainless lossis siab -lub zog alloys, carbide them rau nws tus kheej hauv kev txo qis.

Paub txog dab tsi nyob hauv cov cuab yeej yog ib nrab ntawm qhov sib npaug. Lwm ib nrab yog nkag siab txog cov ntaub ntawv twg uas cov cuab yeej tuaj yeem ua tau thiab cov ntaub ntawv no cuam tshuam li cas rau kev xaiv xovxwm, tonnage xav tau, thiab qhov kawg ntawm kev tsim khoom ceev.

Kev xaiv cov khoom siv thiab xovxwm xav tau

Txhua qhov kev txhim kho hlau stamping qhov project pib nrog cov lus nug tseem ceeb: koj tsim cov hlau dab tsi? Cov lus teb tsim txhua yam hauv qab dej, los ntawm kev suav tonnage thiab nias ceev mus rau lub tswv yim lubrication thiab cov khoom siv tuag. Tau txais qhov kev txiav txim siab no thiab koj cov cuab yeej khiav rau ntau lab lub voj voog. Tau txais nws tsis ncaj ncees lawm thiab koj fim tawg punches, ntau burrs, los yog ib tug tuag stamping xovxwm uas stalls nyob rau hauv qab qhov chaw tuag vim nws khiav tawm ntawm lub zog mid-stroke.

Metals suited rau Progressive Tuag Stamping

Progressive tuag hlau stamping tuav ib tug dav tsev neeg ntawm alloys, tab sis txhua tus coj nws tus cwj pwm mus rau xovxwm. Ntawm no yog yuav ua li cas cov ntaub ntawv zoo tshaj plaws stamping sib piv:

Tsawg- carbon steel dominates zuj zus stamping vim hais tias nws muaj zoo formability, kwv yees lub caij nplooj ntoos hlav, thiab cov khoom uas tsis muaj nqi. Nws punches huv si, khoov tsis muaj cracking, thiab hnav cov cuab yeej ntawm tus nqi tswj tau. Stainless hlau coj kev tiv thaiv corrosion tab sis xav tau ntau dua tonnage thiab ua kom cov punch hnav vim ua haujlwm hnyav, ua rau carbide inserts ib ntus yuav tsum tau.

Aluminium yog lub teeb yuag thiab yooj yim rau shear, tab sis nws khawb tau yooj yim tiv thaiv qhov chaw tuag thiab nyhav rau gall tsis muaj lubrication zoo. Dej-raws li lubricants thiab polished tuag nto yog cov qauv kev coj ua. Copper progressive stamping pab cov ntawv thov hluav taws xob thiab thermal qhov twg conductivity tseem ceeb tshaj lub zog. Cov tooj liab thiab tooj dag yog mos, yooj yim rau kev tsim, thiab tsim cov npoo huv, tab sis lawv qhov kev ua tau zoo txhais tau hais tias burrs tuaj yeem txhim kho yog xuas nrig ntaus - mus rau - tuag clearances tsis tuav nruj.

Kev ntsuas ntau yam feem ntau ua tiav hauv kev tuag ncua ntev li ntawm 0.005 ntiv tes rau cov khoom siv hluav taws xob me me mus txog 0.125 ntiv tes rau cov khoom sib dhos. Coil widths feem ntau yog nyob ntawm ib nti mus rau ib ncig ntawm 24 ntiv tes, txawm hais tias qhov kev txwv tsis pub muaj nyob ntawm lub txaj loj thiab qhov ntev tuag.

Xovxwm Xaiv Txheej Txheem

Cov ntaub ntawv hom thiab ib feem geometry ua ke txiav txim siab seb koj cov xovxwm tuag yuav tsum tau xa. Peb yam tseem ceeb tshaj plaws: lub peev xwm tonnage, stroke ntev, thiab ntsuas ceev.

Tonnageyog lub ncov quab yuam cov xovxwm yuav tsum tsim. Rau kev tho thiab blanking ua haujlwm, kev suav ua raws li cov qauv yooj yim: ib puag ncig ntawm kev txiav cov khoom siv thickness multiplied los ntawm shear lub zog ntawm cov hlau. Rau kev tsim thiab kos duab chaw, kev suav siv lub zog tensile thiab nyiaj rau ib feem geometry. Koj suav cov tub rog thoob plaws txhua qhov chaw ua haujlwm, ntxiv cov khoom thauj los ntawm lub caij nplooj ntoos hlav strippers, lifters, thiab cams, ces siv cov npoo kev nyab xeeb, feem ntau 20 mus rau 30 feem pua. Raws li kev lag luam xyaum, qhov sib npaug sib npaug rau txhua qhov kev txiav los yog tho kev ua haujlwm yogTonnage=Perimeter x Thickness x Shear Strength, qhov twg shear zog yog roughly60% ntawm tensile zograu feem ntau steels.

Tab sis tonnage ib leeg tsis qhia tag nrho zaj dab neeg. Ib lub xovxwm yuav tsum xa txauszoglos ntawm kev mob stroke kom ua tiav tag nrho cov haujlwm yam tsis muaj kev cuam tshuam. Lub tshuab xovxwm tej zaum yuav muaj lub ncov txaus tonnage ntawm qhov chaw tuag hauv qab tab sis tsis muaj lub zog flywheel los txhawb nqa lub zog los ntawm kev sib sib zog nqus kos uas pib ob peb nti hauv qab. Qhov kev sib txawv no dhau los ua qhov tseem ceeb thaum stamping cov ntsuas tuab lossis siab - zog alloys.

Stroke ntevyuav tsum ua kom haum rau qhov sib sib zog nqus ua haujlwm hauv qhov tuag ntxiv rau kev tshem tawm cov sawb nqa thiab ib feem ejection. luv luv stroke thiab koj tsis tuaj yeem tsim lub cev. Ntev dhau lawm nkim sij hawm mus ncig uas tsis yog -kev mus los.

Xovxwm ceevncaj qha tswj hwm kev lag luam tsim khoom. Cov tshuab nias nrog cov pa flywheels ua tau zoo ntawm qhov siab - nrawm nrawm thiab tho qhov yooj yim, niaj hnub ntaus 400 txog 1,200 strokes ib feeb rau kev ua haujlwm ntiav. Servo-tsav presses muaj qhov zoo sib txawv: programmable swb tshaj tawm. Lub servo xovxwm tuaj yeem ua rau lub ram qeeb thaum lub sij hawm tsim ib feem ntawm cov hlab ntsha kom zoo dua cov khoom ntws, ces nrawm los ntawm qhov tsis yog - ua haujlwm feem kom tswj tau cov khoom siv. Raws liMetalForming Magazinepiav qhia, servo presses tso cai rau stampers kom zoo -tune ceev ntawm kev cuam tshuam thaum tswj qhov siab tshaj plaws ua tau tus nqi, ua rau lawv zoo tagnrho rau tooj liab nce stamping thiab lwm yam ntaub ntawv rhiab heev rau kev tshaj tawm.

Servo presses tseem txhawb nqa pendulum hom, qhov twg lub ncej thim rov qab kev taw qhia es tsis ua kom tiav 360-degree kev sib hloov, ua kom lub voj voog luv luv thiab txhawb cov khoom tsim tawm rau qhov chaw uas tsis xav tau tag nrho ram mus ncig. Kev lag luam tawm yog tus nqi: servo presses nqa ib qho kev nqis peev ntau dua li cov khoom siv sib xyaw ua ke, yog li qhov kev xaiv nyob ntawm seb koj qhov geometry thiab cov khoom siv tiag tiag xav tau qhov sib txawv ntawm qhov swb lossis seb qhov yooj yim dua-ceev xovxwm yuav ua li cas.

Thaum kawg, lub txaj loj yuav tsum ua kom haum koj cov hneev taw tuag nrog chav rau clamping kho vajtse thiab cov khoom seem. Ib lub txaj me me ua rau muaj kev cuam tshuam hauv cov txheej txheem tuag lossis yuav tsum tau khiav lub cuab yeej tawm ntawm -nruab nrab, uas ua rau cov thav duab hnav thiab ua kom tsis zoo nyob rau lub sijhawm. Txoj cai dav dav: xaiv lub txaj xovxwm tsawg kawg yog ob mus rau plaub ntiv tes loj dua cov khau tuag hauv txhua qhov kev taw qhia.

Kev xaiv cov khoom thiab xovxwm yog kev txiav txim siab sib koom ua ke. Lub alloy koj stamp txiav txim siab lub zog koj tuag yuav tsum tiv taus, qhov ceev ntawm qhov koj tuaj yeem khiav tau zoo, thiab thaum kawg tus nqi ntawm ib feem ntawm qhov ntim ntau lawm. Xaiv tsis ncaj ncees lawm ntawm ob sab ripples los ntawm tag nrho cov kev pab cuam. Tab sis txawm tias nrog cov khoom zoo meej thiab nias ua ke, tus nqi ntawm kev nce qib tuag stamping tsuas yog pom tseeb thaum koj piv nws lub taub hau - rau - lub taub hau tawm tsam lwm txoj kev stamping, txhua tus muaj nws tus kheej lub zog thiab qhov muag tsis pom kev.

Progressive Die vs Transfer Die vs Compound Tuag

Paub tias kev tuag stamping ua haujlwm li cas yog ib yam. Paub thaum twg nws yog lo lus teb tsis ncaj ncees rau koj feem yog qhov twg cov nyiaj tiag tau txais kev cawmdim lossis nkim. Txhua txoj kev stamping tshwm sim vim qee qhov geometries, ntim, thiab kev kam rau siab xav tau ib txoj hauv kev los ntawm lwm qhov. Lo lus nug tsis yog "tus txheej txheem twg yog qhov zoo tshaj" hauv cov ntsiab lus meej. Nws yog ib txwm "txoj kev twg yog qhov zoo tshaj plaws rau qhov tshwj xeeb ntawm qhov ntim tshwj xeeb no."

Progressive Die vs Hloov Tuag Stamping

Kev sib piv ntau tshaj plaws ntawm cov neeg yuav khoom ntsej muag yog kev nce qib piv rau kev hloov pauv tuag stamping. Ob leeg siv ntau qhov chaw nres tsheb los ua ib feem tiav. Qhov tseem ceeb sib txawv? Yuav ua li cas lub workpiece txav ntawm cov chaw nres tsheb.

Nyob rau hauv ib tug zuj zus tuag, ib feem nyob twj ywm txuas mus rau lub carrier strip los ntawm thawj chaw nres tsheb mus rau qhov kawg. Lub sawb nws tus kheej yog lub thauj mechanism. Qhov tsuas yog cais ntawm qhov chaw nres tsheb zaum kawg. Qhov no ua rau cov khoom ceev ceev thiab tshem tawm inter- chaw nres tsheb tuav, tab sis nws ua rau muaj kev txwv: lub cev yuav tsum txuas nrog lub tiaj tiaj hauv txhua qhov haujlwm.

Hloov tuag stamping siv txoj kev sib txawv. Ib feem yog sib cais los ntawm lub sawb thaum ntxov, feem ntau nyob rau hauv thawj qhov chaw nres tsheb, thiab cov neeg kho tshuab ntiv tes los yog hloov rails lub cev tuaj tos nws thiab txav nws ntawm chaw nres tsheb. Txhua qhov chaw nres tsheb ua haujlwm ntawm qhov tsis sib xws tsis yog ib txoj hlua txuas.

Thaum twg hloov stamping tsim nyog? Peb qhov xwm txheej thawb koj mus rau kev hloov cov cuab yeej:

• Sib sib zog nqus heev- Vim tias tsis muaj cov khoom thauj khoom txwv tsis pub cov khoom ntws, hloov cov tuag tuaj yeem xuas nrig sib sib zog nqus raws li cov khoom siv raw tso cai. Progressive dies yog txwv nyob rau hauv kos qhov tob vim hais tias kev sib txuas ntawm sawb txwv deb npaum li cas hlau yuav txav mus rau hauv kab noj hniav.
• Qhov loj tshaj qhov dav dav- Yog tias koj qhov hneev taw yog qhov loj dua qhov dav dav dav dav (kwv yees li 24 ntiv tes rau kev teeb tsa zoo tshaj plaws), kev hloov pauv tuag ua haujlwm ua ntej - txiav qhov khoob uas tsis muaj qhov dav dav.
• Kev ua haujlwm yuav tsum tau nkag mus rau txhua qhov ntug- Thaum koj xav tau tsim, luas, lossis ntxiv cov yam ntxwv ntawm txhua qhov ib puag ncig ntawm qhov chaw, cov cab kuj nyob rau hauv qhov kev vam meej tuag tau txais txoj hauv kev. Hloov tuag dawb tag nrho cov npoo rau kev siv cuab yeej.

Kev hloov pauv tuag stamping feem ntau yog siv rau lub cev loj, cov khoom siv hauv tsev, thiab hnyav -cov dej num hauv lub tsheb thiab cov ntawv thov kev lag luam uas qhov loj thiab qhov tob ua rau kev tuag tsis zoo. Kev lag luam tawm yog lub sijhawm voj voog: kev hloov pauv ntawm cov chaw nres tsheb ntxiv milliseconds rau ib qho mob stroke, thiab cov cuab yeej siv ntxiv ua kom cov cuab yeej nyuaj. Rau nruab nrab-rau- qhov loj uas xav tau ntau qhov sib sib zog nqus nqus thiab sib sib zog nqus shaping, txawm li cas los xij, kev hloov pauv tuag tseem tsis sib xws.

Progressive Die vs Compound Die vs Single-Stage

Tsis yog txhua txoj haujlwm stamping xav tau ntau qhov chaw nyob hauv ib ntus. Compound tuag stamping ua ntau txoj haujlwm txiav hauv ib zaug xwb nias. Xav txog lub tshuab ntxhua khaub ncaws: koj xav tau ib lub voj voog sab nraud txiav thiab ib lub qhov hauv qhov punched. Ib tug compound tuag ua ob qho tib si ib txhij, tsim ib lub tiaj tus, tiav ib feem nrog ib tug ntaus.

Qhov no ua rau cov khoom siv tuag zoo rau qhov chaw tiaj tus nrog ntau lub qhov, qhov, lossis ib puag ncig cov yam ntxwv uas tsis tas yuav khoov lossis sib sau. Vim tias txhua yam tshwm sim hauv ib qho kev mob stroke, cov khoom sib txuas stamped yuav zoo dua li qhov sib npaug sib npaug, vim tias tsis muaj kev ntxhov siab los ntawm kev ua haujlwm ua ntu zus. Cov cuab yeej sib xyaw kuj tseem tsis tshua muaj nqi thiab nrawm dua los tsim dua li cov cuab yeej nce qib, ua rau nws txaus nyiam thaum cov peev nyiaj nruj thiab ib feem geometry yooj yim.

Qhov kev txwv yog meej: compound tuag tsuas yog txiav. Yog tias koj qhov yuav tsum tau khoov, kos, kos, embosses, lossis ib qho peb - qhov sib txawv, koj xav tau ib qho kev tuag zuj zus los yog kev ua haujlwm sib cais hauv qab.

Tib -theem tooling zaum ntawm qhov yooj yim kawg ntawm cov spectrum. Ib tug tuag, ib txoj haujlwm, ib leeg mob stroke. Xav tau lub qhov punched? Ib theem. Xav tau ib tug flange khoov? Lwm theem nyob rau hauv ib tug txawv tuag. Ib feem yog manually lossis semi- tsis siv neeg txav ntawm kev ua haujlwm. Txoj hauv kev no ua haujlwm rau cov ntim tsawg heev, qhov loj heev uas tsis tuaj yeem haum rau hauv ntau- chaw nres tsheb cov cuab yeej, lossis kev ua qauv uas koj tau lees paub cov duab kos ua ntej ua rau kim ntau- chaw nres tsheb tuag.

Tus nqi ib feem ntawm ib qho - cov cuab yeej siv theem siab yog qhov siab vim yog lub sijhawm ua haujlwm thiab tuav lub sijhawm, tab sis cov cuab yeej ua ntej kev nqis peev tsawg tsawg. Rau cov khoom lag luam txhua xyoo nyob rau hauv ob peb txhiab feem, nws feem ntau ua rau muaj kev nkag siab txog nyiaj txiag kom nqus tau ntau dua rau ib feem ntawm - ib feem ntawm kev ua haujlwm ntau dua li siv rau tus lej ntawm kev tuag zuj zus uas yuav siv sij hawm ntau lub hlis los tsim.

Kev Txiav Txim Siab Raws li Volume thiab Geometry

Kev xaiv txoj kev yog los mus rau plaub qhov sib txawv: pes tsawg qhov koj xav tau hauv ib xyoos, lawv loj npaum li cas, lawv geometrically complex, thiab nruj npaum li cas koj kam rau ua. Ntawm no yog yuav ua li cas cov variables map hla txoj kev:

Ob peb txoj cai tsim tawm los ntawm qhov kev sib piv no. Yog tias koj qhov chaw tiaj tus nrog lub qhov thiab tsis tas yuav tsum muaj kev sib sau, cov khoom sib txuas yuav ua rau koj muaj qhov zoo tshaj plaws ntawm cov cuab yeej siv thiab rau ib qho kev lag luam. Yog tias koj ib feem muaj qhov khoov, cov ntaub ntawv, lossis cov yam ntxwv nyuaj thiab koj xav tau ntau dua 50,000 ib xyoos ib zaug, kev tuag yuav luag txhua lub sijhawm. Yog tias koj ib feem xav tau kev sib sib zog nqus nqus, lub cev loj, lossis xav tau kev ua haujlwm ntawm txhua tus npoo, hloov pauv tuag yog koj txoj hauv kev.

Ib qho -theem tooling tsis tshua muaj qhov ntev - cov kev daws teeb meem. Nws ua haujlwm raws li tus choj: ua pov thawj qhov tsim ntawm qhov ntim tsawg ua ntej cog lus rau ntau - chaw nres tsheb theem cuab yeej, lossis tuav ib qho - tawm qauv khiav qhov twg cov geometry tseem tab tom hloov mus. Thaum cov khoom lag luam pom zoo rau kev nqis peev, feem ntau cov tuam txhab lag luam tsiv mus rau kev vam meej lossis hloov pauv tuag thiab tsis txhob tig rov qab.

Ib qho nuance feem ntau tsis saib xyuas: cov txheej txheem no tsis yog sib koom ua ke hauv kev tsim khoom. Ib feem yuav pib lub neej nyob rau hauv ib tug zuj zus tuag rau thawj tsim thiab ces tsiv mus rau ib tug thib ob ib leeg -theem ua hauj lwm rau ib tug feature uas ua tsis tau tejyam thaum txuas nrog rau cov cab kuj strip. Kev nkag siab qhov twg txhua txoj kev ua tau zoo tso cai rau koj los tsim cov phiaj xwm tsim khoom uas ua ke nrog lawv cov tswv yim es tsis yog yuam ib txheej txheem ua txhua yam.

Lub moj khaum sib piv qhia meej tias txoj hauv kev haum rau koj qhov geometry thiab ntim. Dab tsi nws tsis qhia yog tus nqi qauv tom qab txhua qhov kev xaiv, tshwj xeeb yog dab tsi tsav cov cuab yeej siv tus nqi, qhov twg cov ntsiab lus ntawm kev lag luam poob qis, thiab qhov kev lag luam ceev tau txhais li cas rau hauv - ib feem txuag ntawm qhov ntsuas.

Tus nqi qauv thiab thaum Progressive Stamping Them tawm

Ntawm no yog qhov kev mus ncig ua ntej tshaj plaws - lub sijhawm cov neeg yuav khoom: tus nqi tag rau ntawm qhov kev tuag zoo li loj heev kom txog thaum koj faib nws los ntawm cov khoom uas nws tsim. Progressive tuag stampings tuaj yeem raug nqi feem ntawm ib xees ib thooj ntawm ntim, tab sis qhov ntawd tsuas yog tshwm sim thaum cov cuab yeej ua ntej kev nqis peev, ntim ntau lawm, thiab nias ceev kom raug. Misjudge ib qho ntawm peb thiab kev lag luam poob.

Tooling Nqi Tsav Tsheb

Dab tsi txiav txim siab seb koj qhov kev tuag raug nqi $ 15,000 lossis $ 150,000? Muaj ntau yam sib txawv ntawm ib leeg:

• Tus naj npawb ntawm cov chaw nres tsheb- Txhua qhov haujlwm (pierce, daim ntawv, npib, khoob) yuav tsum muaj nws qhov chaw nres tsheb. Ib qho yooj yim dawb paug-thiab- khoov ib feem yuav xav tau 4 mus rau 6 chaw nres tsheb. Ib qho kev sib txuas nrog ntau qhov khoov, embosses, thiab nruj - cov yam ntxwv siab ntev tuaj yeem xav tau 12 txog 20 chaw nres tsheb. Txhua qhov chaw nres tsheb ntxiv lub sijhawm machining, khoom siv, thiab engineering.
• Tuag complexity thiab tsim nyuaj- Kev sib sib zog nqus nqus, hauv -tuag tapping, cam- ua haujlwm sab nraud, thiab ntau-axis tsim txhua yam yuav tsum muaj cov txheej txheem tshwj xeeb uas ua rau ob qho tib si tsim thiab tsim nqi.
• Ntxig khoom- Carbide inserts kav ntev dua li cov cuab yeej hlau (D2 lossis SKD11) tab sis raug nqi ntau zaus ntau dua. Rau kev ua haujlwm ntev ntev stamping ntau tshaj lab ntawm cov voj voog ntawm kev saib xyuas, carbide them rau nws tus kheej. Rau cov kev pab cuam luv luv, cov cuab yeej steel muab lub neej txaus ntawm kev nqis peev qis.
• Kev kam rau siab- Tighter tolerances xav tau kev ua kom zoo dua ntawm cov khoom siv tuag, chaw nres tsheb nyiaj npib ntxiv, thiab kev sim ua ntau dua. Txhua feem kaum ntawm ib txhiab koj nruj ntxiv tus nqi.
• Tuag kev cia siab- Ib qho tuag ua rau 500,000 tag nrho cov khoom siv cov khoom sib txawv thiab kev tsim kho dua li ib qho tsim rau 10 lab. Kev cia siab ntev lub neej txhais tau hais tias cov hlau zoo tshaj plaws, kev tsim kho kom yooj yim txij nkawm, thiab cov lus qhia muaj zog dua.
• Kev txhim kho thiab kev sim- Qhov no yog tus nqi feem ntau quotes understate. Cov txheej txheem rov ua dua ntawm kev sib tw khiav, ntsuas, kho qhov chaw nres tsheb rau lub caij nplooj ntoos hlav, thiab rov ua dua - khiav tuaj yeem ua rau cov cuab yeej nqi nws tus kheej rau cov geometry nyuaj.

Cov ntaub ntawv kev lag luam qhia txog qhov ntau kom meej. Cov kev vam meej yooj yim tuag nrog kev tho yooj yim - thiab - khoov kev ua haujlwm feem ntau poob ntawm $ 10,000 thiab $ 25,000. Nruab nrab- kev siv cov cuab yeej nyuaj nrog 8 mus rau 14 chaw nres tsheb thiab cov av nruj dua nyob hauv thaj tsam $ 25,000 txog $ 60,000, uas yog qhov chaw siv tsheb thiab hluav taws xob feem ntau tsom. Kev tuag ntau dua $60,000 feem ntau suav nrog kev kos duab sib sib zog nqus, carbide inserts rau cov ntaub ntawv abrasive, lossis pob khoom tshwj xeeb sensing.

Qhov kev pom tseem ceeb? Koj tus qauv tsim ncaj qha tswj cov cuab yeej tus nqi. Txhua yam uas koj ntxiv yuav tsum muaj chaw nres tsheb. Txhua qhov kev ua siab ntev ntev uas koj tau teev tseg yuav tsum muaj cov khoom siv tuag zoo dua thiab ntau lub voj voog sim. Kev tsim qauv yooj yim ua ntej kev cog lus siv cuab yeej yog qhov siab tshaj plaws - tus nqi txo nqi muaj.

Volume Thresholds thiab Per -Part Economics

Progressive tuag stamping muaj tus nqi nkhaus tsis zoo li yuav luag txhua yam kev tsim khoom. Kev nqis peev thawj zaug yog qhov siab, tab sis tus nqi qis ntawm txhua qhov ntxiv yog ze li qhov tsis txaus ntseeg: tsuas yog cov khoom siv raw thiab lub sijhawm nias. Qhov no tsim ib qho kev sib tw ua yeeb yam uas cov cuab yeej ua tau zoo hloov pauv ntawm cov khoom kim heev mus rau qhov tsim nyog pom tseeb.

Qhov crossover tshwm sim qhov twg? Rau ntau daim ntawv thov,50,000 txog 100,000 units txhua xyoosawv cev rau qhov chaw pib qhov kev txhim kho cov cuab yeej ua kom pom tseeb ROI tshaj lwm txoj hauv kev xws li laser txiav, CNC xuas nrig ntaus, lossis ib zaug -theem tuag. Ultra- qhov chaw yooj yim tuaj yeem ua pov thawj qhov peev ntawm 30,000 units. Cov khoom tsis sib xws nrog siab rau - cov nqi hloov pauv tuaj yeem tawg txawm tias sai dua.

Xav txog lej. Yog tias tus bracket raug nqi $ 5.00 ib chav los ntawm kev txiav laser nrog kev ua haujlwm thib ob, thiab tib lub bracket raug nqi $ 0.50 rau ib chav los ntawm kev nce qib stamping, koj txuag tau $ 4.50 ib feem. Ib qho $35,000 tuag peev them rov qab rau hauv qis dua 8,000 qhov chaw. Ntawm 50,000 units txhua xyoo, qhov nyiaj rov qab tuaj txog tsawg dua ob lub hlis ntawm kev tsim khoom.

Xovxwm ceev ua kom muaj kev lag luam ntxiv. Kev kub ceev ceev nrooj tuag stamping ntawm 200 rau 600+ strokes ib feeb txhais tau hais tias ib qho xovxwm tuaj yeem tsim tau kaum tawm txhiab qhov chaw ib zaug. Ntawm cov nqi ntawd, lub sijhawm ua haujlwm thiab lub sijhawm siv lub tshuab faib rau txhua ntu yuav luag tsis muaj dab tsi. Qhov koj cov xovxwm khiav nrawm dua, qhov qis dua koj li ntawm - feem nyiaj siv ua haujlwm, uas yog vim li cas cov kev pabcuam tuag hlau stamping tau hais txog kev nrawm nrawm raws li lub zog sib tw tseem ceeb rau siab - cov haujlwm ntim.

Txoj kev sib raug zoo ua haujlwm rov qab thiab. Hauv qab qhov ntim ntawm crossover, tooling amortization dominates per -part cost. Ib qho $ 50,000 tuag kis thoob plaws 5,000 qhov chaw ntxiv $ 10.00 ib thooj xwb hauv kev siv, ua lwm txoj hauv kev zoo nkauj dua.

Lead Time Expectations

Tooling tsis tshwm ib hmos. Los ntawm kev tsim tawm mus rau kev tsim khoom- cov khoom tsim nyog, cia siab tias yuav muaj sijhawm ntsuas hauv lub hlis, tsis yog lub lis piam. Nov yog qhov kev nce qib ib txwm:

• Tuag tsim thiab engineering (3-5 lub lis piam)- Kev teeb tsa strip, chaw nres tsheb sib txuas, FEA simulation rau kev ua haujlwm, thiab cov duab kos duab ntxaws.
• Kev yuav khoom (1-3 lub lis piam)- Ordering tool steel blocks, carbide inserts, standard components (caij nplooj ntoos hlav, guide pins, sensors), feem ntau overlapping nrog tsim.
• Machining, sib tsoo, thiab kho cua sov (5-8 lub lis piam)- CNC machining ntawm cov khau tuag, daim hlau, thiab cov khoom ntxig; xaim EDM rau complex profiles; Thaum tshav kub kub kho kom harden txiav Cheebtsam; precision nto sib tsoo rau qhov kawg qhov ntev.
• Kev sib dhos thiab lub rooj zaum haum (1-2 lub lis piam)- Sib sau tag nrho cov khoom, xyuas qhov haum thiab tshem tawm, teeb tsa lub sijhawm.
• Kev sim thiab rov ua dua (2-4 lub lis piam)- Khiav cov qauv sim, ntsuas qhov loj me, kho qhov chaw nres tsheb rau lub caij nplooj ntoos hlav, rov- khiav mus txog qhov chaw ua tau raws li qhov tshwj xeeb.
• Kev tsim khoom tsim nyog (1-2 lub lis piam)- Khiav ntawm ntau lawm ceev, txheeb xyuas qhov muaj peev xwm SPC, thawj tsab xov xwm tshuaj xyuas pom zoo.

Tag nrho ncua sij hawm rau qhov siab -zoo zuj zus tuag feem ntau khiav 12 mus rau 20 lub lis piam. Cov cuab yeej yooj yim nrog cov chaw nres tsheb tsawg tuaj yeem ua rau 8 mus rau 10 lub lis piam. Complex tuag nrog nruj tolerances lossis ntau qhov chaw tsim khoom tuaj yeem ncab ntev dua, tshwj xeeb tshaj yog thaum kev sim qhia cov teeb meem springback uas yuav tsum tau kho ntau lub voj voog.

Ib qho kev pheej hmoo ncua sij hawm uas ntes cov neeg yuav khoom tawm tsam: lig - theem tsim kev hloov pauv. Kev hloov kho qhov tuag tom qab machining tiav tuaj yeem raug nqi ntau npaum li ib nrab ntawm cov cuab yeej qub thiab ntxiv lub lis piam rau lub sijhawm. Kev tsim kom khov ib feem ua ntej steel txiav pib tsis yog xaiv tau. Nws yog tib lub sijhawm tseem ceeb tshaj plaws thiab kev tiv thaiv nyiaj txiag muaj.

Tus nqi, ntim, thiab ncua sij hawm tsim daim duab peb sab kev lag luam ntawm txhua qhov kev pabcuam stamping. Tab sis kev lag luam ib leeg tsis lav tias kev vam meej. Lwm ib nrab ntawm qhov sib npaug, tuav ib feem zoo thoob plaws ntau lab lub voj voog thaum ua kom cov neeg tuag nyob rau hauv qhov siab tshaj plaws, txiav txim siab seb cov kev nyiam ntawm ib feem ntawm - ib feem ntawm kev lag luam yeej tuav hauv kev tsim khoom.

Tolerances, Kev Tswj Xyuas Zoo, thiab Kev Pabcuam Tuag

Txaus siab rau - ib feem kev lag luam txhais tau tias tsis muaj dab tsi yog tias cov khoom lawv tus kheej tawm ntawm qhov tshwj xeeb ib nrab los ntawm kev tsim khoom. Kev nce qib stamping tuag tuaj yeem tuav tau qhov zoo tshaj plaws, tab sis tsuas yog thaum koj nkag siab tias qhov kev zam qhov ntev npaum li cas yog qhov tseeb rau txhua hom kev ua haujlwm, yuav ua li cas los saib xyuas qhov zoo ntawm lub sijhawm, thiab kev saib xyuas zoo li cas ua rau cov cuab yeej ua tau zoo li tshiab hla ntau lab lub voj voog. Qhov no yog tshooj feem ntau cov neeg xa khoom hla, thiab nws yog ib qho uas cais cov kev pabcuam du los ntawm kev tawm dag zog tua hluav taws.

Dimensional Tolerances thiab Precision Peev Xwm

Dab tsi ntawm precision koj tuaj yeem xav tau los ntawm precision tuag stamping? Cov lus teb nyob ntawm qhov kev ua haujlwm uas tsim cov yam ntxwv. Txiav, sib sau, thiab npib txhua tus muaj qhov sib txawv ua tau raws qhov ntev:

Txiav kev ua haujlwm xa cov kev ua kom nruj tshaj plaws vim tias shearing yog ib qho kev txiav txim siab zoo. Lub punch nkag mus rau hauv cov khoom, shear pib, thiab tawg propagates los ntawm qhov seem thickness. Tsuav qhov clearances yog lawm thiab cov cuab yeej ntse, qhov - mus rau - qhov thiab qhov - mus rau - ntug qhov ntev tseem zoo ib yam.

Kev sib sau ua siab ntev yog dav dua vim tias khoov qhia txog springback, elastic rov qab ntawm cov hlau tom qab cov punch retracts. Springback sib txawv nrog cov khoom siv zog, thickness, khoov vojvoog, thiab txawm tias coil txoj hauj lwm nyob rau hauv lub tshav kub. Cov kws paub txog kev tuag tau them nyiaj los ntawm overbending, ntxiv cov chaw nres tsheb, lossis siv cov nyiaj npib siab ntawm qhov khoov apex, tab sis qee qhov kev hloov pauv tseem nyob hauv tus txheej txheem.

Muaj ntau yam cuam tshuam rau qhov tseeb ntawm txhua hom kev ua haujlwm:

• Tuag mob- Punch npub ua rau cov burrs loj dua thiab hloov qhov zoo ntawm qhov loj. Ib qho hnav ua qhov chaw tso cai rau cov khoom siv caij nplooj ntoos hlav ntxiv.
• Cov khoom sib xws- Variation nyob rau hauv thickness, hardness, los yog grain orientation nyob rau hauv ib tug coil ntau qhia ib feem - rau - ib feem sib txawv uas txawm zoo meej tooling tsis tuaj yeem tshem tawm.
• Xovxwm deflection- Nyob rau hauv load, nias thav duab deflect. Yog hais tias deflection tshaj tuag clearance margins,qhov zoo thiab burr theem degrade, tshwj xeeb tshaj yog tawm ntawm - chaw nres tsheb.
• Thermal expansion- Thaum lub sij hawm ncua kev khiav ntawm kev kub ceev, kev sib txhuam kub ua rau cov khoom tuag nthuav dav me ntsis. Kev tuag khiav ntawm 600 SPM rau yim teev tuaj yeem hloov qhov ntev ntawm 0.0005 "rau 0.001" raws li qhov kub thiab txias.
• Pilot raug- Txij li thaum cov kws tsav dav hlau sau npe rau ntawm txhua qhov chaw nres tsheb, ib qho hnav ntawm tus tsav tus pins lossis elongation ntawm tus tsav lub qhov ncaj qha txhais mus rau qhov yuam kev ntawm qhov qis qis.

Lub tswv yim takeaway? Qhia qhov kam rau ua raws li kev ua haujlwm, tsis yog kev ntshaw. Kev kam rau siab ntawm ± 0.001" ntawm qhov kev tshem tawm uas sib koom nrog 0.020"- cov khoom siv loj loj yuav siv nyiaj ntau ntawm cov chaw nres tsheb npib ntxiv thiab kev tu ntau zaus tuag. Progressive precision hlau stampings ua tiav lawv cov kev lag luam zoo tshaj plaws thaum nruj kam rau ua tau tshwj tseg rau cov yam ntxwv tseem ceeb thiab cov seem ntawm qhov siv cov qauv precision ntau yam.

Kev Tswj Xyuas Kev Tswj Xyuas Zoo thiab Kev Tshawb Fawb

Cov koob yees duab mounted ntawm qhov tuag tawm ntes cov duab ntawm txhua qhov chaw, sib piv cov profiles tiv thaiv cov qauv kub ntawm cov nqi uas ua kom nrawm nrog cov xovxwm. Cov khoom uas tau tshaj tawm raws li qhov xav tias yuav hloov pauv tau, thiab cov qauv kev tshuaj ntsuam xyuas rov qab rau hauv lub voj voog kev npaj kho.

Tuag tu thiab tiv thaiv tsis ua hauj lwm

Kev tuag zuj zus tsis yog txheej txheem -thiab- tsis nco qab cov cuab yeej. Nws yog ib qho cuab yeej precision nyob rau hauv tas li txhua yam kev nyuaj siab, thiab tsis muaj kev qhuab qhia, zoo degrades maj mam mus txog rau thaum nws tsis dheev. Cov hom kev ua tsis tau zoo tshaj plaws hauv kev tsim khoom muaj xws li:

• Punch tawg- Cov me me- txoj kab uas hla punches yooj yim rau lateral loads los ntawm strip misalignment los yog qaug zog los ntawm ntau lab ntawm kev cuam tshuam mus. Kev tawg tsim cov yam ntxwv uas ploj lawm thiab tuaj yeem ua rau cov chaw nyob ib sab puas.
• Galling- Cov ntaub ntawv hloov ntawm lub sawb mus rau qhov chaw tuag, tshwj xeeb tshaj yog nyob rau hauv cov chaw tsim khoom. Galling ua rau khawb ntawm qhov chaw thiab nce zuj zus mus txog thaum lub chaw nres tsheb polished lossis rov ua dua. Raws liMetalForming Magazinesau ntawv, galling yog ib qho ntawm cov neeg tuag saum toj kawg nkaus-cov teeb meem ntsig txog kev tshaj tawm hauv khw xovxwm, thiab hais txog nws yuav tsum tau tshem tawm kom raug, npaj nto, thiab lubrication hauv qhov kev txiav txim tseem ceeb ntawd.
• Lub sijhawm drift- Caij nplooj ntoos hlav qaug zog nyob rau hauv strippers los yog lifters hloov tus txheeb ze txoj hauj lwm ntawm lub strip thaum ua hauj lwm. Dab tsi pib raws li kev sau npe zoo meej maj mam hloov, qhia txog qhov tsis raug ntawm txhua qhov chaw nres tsheb.
• Caij nplooj ntoos hlav qaug zog- Ob lub tshuab hluav taws xob coil springs thiab nitrogen gas springs poob zog dhau sijhawm. Txo stripper siab ua rau tsis tiav stripping thiab ib feem lifting. Tsis muaj zog lifter springs ua rau luag cov cim los yog luv pub.
• Pilot hnav- Hardened li lawv yog, pilots nws thiaj li hnav ntawm lub taub hau, ua kom lub clearance rau pilot qhov thiab loosening strip rau npe.

Kev tiv thaiv kev saib xyuas ua raws li lub voj voog - raws sij hawm es tsis yog daim ntawv qhia hnub -raws li ib qho. Ib tug tuag khiav ntawm 400 SPM accumulates hits deb tshaj li ib tug khiav ntawm 60 SPM, yog li lub sij hawm ib leeg yog ib tug tsis zoo kev pab cuam. Tej ntu zoo li no:

• Txhua qhov kev khiav haujlwm (setup / teardown)- Ntxuav qhov chaw tuag, tshuaj xyuas qhov pom kev puas tsuaj, txheeb xyuas cov haujlwm sensor, lubricate cov khoom txav.
• Txhua 50,000 txog 100,000 hits- Tshawb xyuas cov npoo npoo rau hnav los yog chipping, xyuas cov kev taw qhia ntawm tus tsav tsheb, xyuas lub caij nplooj ntoos hlav quab yuam nrog lub ntsuas, thiab tshuaj xyuas qhov chaw tsim rau galling lossis buildup.
• Txhua 200,000 txog 500,000 hits- Ntxig lossis hloov cov punches thiab cov nyees khawm tuag, hloov cov neeg tsav tsheb uas hnav, kho cov nitrogen springs yog tias lub zog poob qis dua qhov pib, rov- tshuaj xyuas cov ntawv qhia hnav.
• Txhua 1,000, 000+ hits- Tag nrho cov tuag teardown, tshuaj xyuas tag nrho cov khoom tiv thaiv tus thawj specifications, hloov tej yam khoom uas qhia txog kev coj, re- tsim nyog nrog thawj tsab xov xwm tshuaj xyuas ua ntej rov qab mus rau ntau lawm.

Proactive sharpening yog ib qho kev tiv thaiv zoo tshaj plaws. Ib qho punch uas yog reground ntawm thawj lub cim ntawm kev loj hlob burr tshem tawm ob peb txhiab ntawm ib nti ntawm nws lub ntsej muag thiab rov qab mus rau kev pabcuam nrog kev txiav tshiab. Tos ntev dhau lawm thiab cov punch chips, yuav tsum tau hloov tag nrho ntawm tus nqi ntau dua thiab ntev dua downtime. Cov khw feem ntau taug qab qhov siab qhov siab raws li qhov ntsuas qhov ntsuas: thaum burrs tshaj qhov chaw pib (feem ntau 10% ntawm cov khoom tuab), kev ua kom tiav yog vim li cas.

Lub hom phiaj ntawm tag nrho cov kev coj ua no yog ncaj nraim: ua kom lub plhom feem zoo ib yam li thawj. Progressive tuag thiab stamping muab qhov sib xws, tab sis tsuas yog thaum cov txheej txheem zoo thiab kev saib xyuas kev qhuab ntuas phim qhov tseeb ua rau hauv lub cuab yeej nws tus kheej. Qhov twg zaj dab neeg no tau txais txiaj ntsig ntau dua yog nyob ntawm thaj tsam, cov xwm txheej uas txawm tias kev saib xyuas zoo tshaj plaws tsis tuaj yeem kov yeej cov txheej txheem tseem ceeb uas ua rau txoj kev tsim khoom sib txawv yog qhov kev xaiv zoo dua.

Kev txwv thiab thaum Progressive Die Stamping tsis zoo tagnrho

Tsis muaj txheej txheem tsim khoom yog universally raug, thiab tuag stamping nrog cov cuab yeej ua tau zoo yog tsis muaj qhov zam. Kev ntsuam xyuas ncaj ncees ntawm qhov twg cov txheej txheem no poob qis yuav txuag nyiaj ntau dua li kev ua kom zoo dua tom qab txoj kev tsis ncaj ncees twb tau cog lus lawm. Ntawm no yog qhov kev vam meej tuag tsoo lawv qab nthab.

Volume thiab Geometry txwv

Kev lag luam tsis zam txim rau hauv qab qee qhov pib. Ib qho kev tuag raug nqi $ 30,000 txog $ 250,000 tsis tuaj yeem ua pov thawj nws tus kheej thaum cov khoom txhua xyoo zaum qis dua 30,000 txog 50,000 qhov chaw. Ntawm qhov ntau, CNC laser txiav los yog turret xuas nrig ntaus muab cov khoom sib piv nrog ze-zero tooling peev, txawm tias ib qho nqi ntau dua.

Qhov luaj li cas qhia lwm tus ciam teb nyuaj. Vim hais tias lub workpiece yuav tsum taug kev los ntawm qhov tuag ntawm ib tug cab kuj strip, koj ib feem hneev taw yog txwv los ntawm cov tswv yim dav dav, feem ntau maxing tawm ib ncig ntawm 24 ntiv tes. Cheebtsam loj dua li ntawd, xav txog cov qauv vaj huam sib luag, cov ntaub thaiv loj, lossis cov khoom siv hauv lub cev, tsuas yog tsis tuaj yeem nqa los ntawm cov cuab yeej nce qib.

Kev sib sib zog nqus nqus nthuav qhia qhov kev txwv zoo sib xws. Cov cab cab kuj txwv cov khoom ntws mus rau hauv cov kab noj hniav. Thaum koj qhov geometry xav kom kos qhov tob tshaj li ntawm 1.5 npaug ntawm txoj kab uas hla, txoj hlua txuas txuas tau tshaib plab rau qhov chaw tsim khoom thiab ua rau kua muag. Ib qho kev hloov pauv tuag, uas ua haujlwm tsis sib xws nrog tsis muaj kev sib txuas, tshem tawm qhov kev txwv tag nrho.

Cov khoom uas xav tau kev ua haujlwm los ntawm ntau cov lus qhia kuj thawb dhau qhov kev txhim kho cov cuab yeej tuaj yeem ua tiav hauv ib qho dhau los. Sab- tho, nraub qaum- tsim, lossis cov yam ntxwv uas xav tau kev siv cuab yeej siv los ntawm cov ces kaum uas tsis yog ncaj nraim nce thiab nqis yuav tsum tau cam- tsav sab ua, uas ntxiv cov nqi tseem ceeb thiab qhov nyuaj. Hauv qhov xwm txheej hnyav, kev ua haujlwm thib ob sab nraum qhov tuag yuav ua tsis tau.

Design Constraints los xav txog

Cov ntaub ntawv thickness muaj cov ciam teb. Feem ntau kev tuag txheej txheem ntsuas ntawm 0.005 thiab 0.125 ntiv tes. Mus thinner thiab strip buckles thaum pub mis. Mus thicker thiab tonnage xav tau escalate, nias speeds poob, thiab punch lub neej shortens dramatically. Rau cov phaj hnyav ua haujlwm siab tshaj 0.125 ntiv tes, lwm hom stamping tuag lossis CNC txheej txheem feem ntau ua pov thawj ntau dua.

Yam tsawg kawg nkaus qhov loj me yog tswj hwm los ntawm txoj cai ncaj nraim: lub qhov taub yuav tsum tsis txhob me dua li cov khoom tuab. Ua txhaum no 1: 1 piv thiab punch breakage tus nqi nce sharply. Rau 0.040-inch-thick strip, uas txhais tau tias tsis muaj qhov hauv qab 0.040 ntiv tes yam tsis lees txais cov cuab yeej tsis tu ncua thiab cov nqi kho kom siab.

Qhov kev xav tau ntawm tus cab kuj yog qhov txwv. Koj ib feem yuav tsum nyob twj ywm rau lub cev txuas nrog lub sawb thoob plaws txhua qhov chaw nres tsheb kom txog thaum kawg txiav tawm. Qee qhov geometries, tshwj xeeb tshaj yog cov uas muaj kev sib sau ntawm txhua qhov npoo lossis qhov sib sib zog nqus uas yuav cuam tshuam tus cab kuj, tsuas yog tswj tsis tau qhov kev sib txuas. Thaum koj ntsib qhov no, kev hloov pauv tuag dhau los ua qhov laj thawj lwm txoj hauv kev.

Kev ua hauv qab no tsim nyog xav txog thiab. Stamped qhov chaw feem ntau xav tau deburring, plating, kev kho cua sov, los yog kev sib dhos ua haujlwm uas ntxiv tus nqi thiab lub sij hawm ua ntej tshaj qhov tawm ntawm xovxwm. Yog tias koj daim ntawv thov xav tau qhov yuav tsum tau ua kom nruj ntawm qhov chaw los yog xa tawm -stamp thermal processing, muab cov kauj ruam thib ob rau hauv kev sib piv tus nqi tag nrho. Ib feem uas zoo nkaus li pheej yig los ntawm kev tuag thiab stamping kab yuav tsis zoo li pheej yig tom qab peb qhov kev ua tiav ntxiv.

Xaiv qhov kev vam meej tuag stamping thaum lub xyoo ntim ntau tshaj 50,000 units, ib feem geometry fits nyob rau hauv strip -dav txwv, kos qhov tob yog nruab nrab, thiab tus tsim yog khov. Zam kom tsis txhob muaj qhov ntim tsawg, qhov loj lossis qhov tob tob, cov yam ntxwv xav tau ntau yam - cov cuab yeej taw qhia kev nkag, lossis tus qauv tsim tseem hloov zuj zus. Nyob rau hauv cov ntaub ntawv no, hloov tuag, compound tuag, los yog CNC machining feem ntau xa cov txiaj ntsig zoo ntawm qhov kev pheej hmoo ntawm kev pheej hmoo qis.

Cov kev txwv no tsis yog qhov tsis zoo hauv cov txheej txheem. Lawv yog cov ciam teb uas txhais tau tias qhov kev vam meej tuag stamping excels piv rau qhov twg lwm txoj kev coj mus. Paub txog lawv thaum ntxov, ua ntej cov cuab yeej siv nyiaj tau cog lus, yog dab tsi cais lub qhov dej zoo -kev tswj hwm kev pab cuam los ntawm ib qho uas hlawv nyiaj txiag caum cov kev daws teeb meem tsis raug. Cov lus nug tiag tiag rau feem ntau pab pawg ua tau zoo: thaum koj tau lees paub tias cov cuab yeej ua tau zoo yog qhov haum, koj yuav ua li cas rau qhov project los ntawm kev tsim thawj zaug los ntawm kev tsim khoom, thiab koj yuav ntsuas cov neeg muag khoom uas yuav tsim thiab khiav koj txoj kev tuag li cas?

Yooj yim pierce-thiab- khoov tuag nrog 4-6 chaw nres tsheb feem ntau yog li ntawm $10,000 txog $25,000. Nruab nrab- cov cuab yeej nyuaj nrog 8-14 chaw nres tsheb poob ntawm $ 25,000 thiab $ 60,000. High-complexity tuag nrog sib sib zog nqus draws, carbide inserts, los yog tshwj xeeb sensors yuav tshaj $60,000. Cov qauv tsim ncaj qha cuam tshuam rau tus nqi txij li txhua qhov tshwj xeeb ntxiv yuav tsum muaj chaw nres tsheb ntxiv, thiab nruj dua qhov kev cia siab xav tau kev ua haujlwm zoo dua thiab kev sim ntau dua.

3. Qhov ntim dab tsi ua rau kev nqis peev hauv cov cuab yeej ua tiav tiav?

Cov ntawv thov feem ntau ncav cuag qhov tseeb ROI crossover ntawm 50,000 txog 100,000 ib xyoos ib zaug piv rau lwm txoj hauv kev xws li laser txiav lossis CNC xuas nrig ntaus. Ultra- tej yam yooj yim tej zaum yuav ua pov thawj peev ntawm 30,000 units, thaum complex qhov chaw nrog siab rau ib tug - tej lwm yam nqi yuav tawg sai dua. Kev ua lej yog qhov yooj yim: faib koj cov cuab yeej peev los ntawm ib feem ntawm - kev txuag nyiaj rau lwm txoj hauv kev. Hauv qab qhov ntim ntawm crossover, tooling amortization dominates per -ib feem nqi thiab ua rau txoj kev yooj yim dua kev lag luam.

4. Dab tsi kam rau siab tuaj yeem ua tiav tuag stamping tiav?

Achievable tolerances txawv raws li hom kev ua haujlwm. Piercing thiab blanking ua haujlwm tuav ± 0.001 txog ± 0.003 ntiv tes, nrog ± 0.0005 ntiv tes tau siv cov cuab yeej precision. Khoov thiab sib sau feem ntau ua tiav ± 0.005 txog ± 0.015 ntiv tes vim qhov hloov pauv hloov pauv. Kev ua haujlwm npib xa ± 0.001 txog ± 0.002 ntiv tes los ntawm cov khoom siv hauv qab siab tonnage. Cov yam tseem ceeb uas cuam tshuam rau qhov tseeb suav nrog kev tuag, cov khoom sib xws hauv cov coil ntau, nias deflection nyob rau hauv load, thermal expansion thaum lub sij hawm ntev khiav, thiab pilot pin raug rau kev sau npe strip.

5. Nws siv sijhawm ntev npaum li cas los tsim kom muaj kev vam meej ntawm kev tsim khoom?

Ib txoj haujlwm tseem ceeb ntawm kev tuag ua haujlwm tau 12 txog 20 lub lis piam los ntawm kev tsim tawm mus rau kev tsim khoom- qhov tsim nyog. Lub sijhawm ncua sijhawm ua haujlwm raws li hauv qab no: tuag tsim thiab engineering (3-5 lub lis piam), kev yuav khoom (1-3 lub lis piam, feem ntau sib tshooj), machining thiab kev kho cua sov (5-8 lub lis piam), sib dhos thiab haum (1-2 lub lis piam), sim thiab iteration (2-4 lub lis piam), thiab tsim nyog tsim (1-2 lub lis piam). Cov cuab yeej yooj yim tuaj yeem ua rau 8-10 lub lis piam, thaum txoj kev tuag nrog kev sib sau nruj yuav ntev dua. Cov qauv tsim qauv hloov pauv tom qab pib machining tuaj yeem ntxiv lub lis piam thiab tus nqi tseem ceeb.
