Cov nqi cuab yeej zaum hauv qab kev vam meej tuag, ua rau lawv muaj zog haum rau cov khoom me me mus rau nruab nrab qhov twg precision outweighs throughput ceev.

Hloov Tuag rau Loj lossis tob -Drawn Geometry

Qee qhov tsuas yog loj dhau los yog xav tau ntau dhau peb -sib nqus ua kom nyob twj ywm rau hauv cov khoom thauj. Hloov stamping daws qhov no los ntawm kev sib cais ib tus neeg qhov khoob ntawm lub kauj ntawm lub chaw nres tsheb thawj zaug, tom qab ntawd hloov kho txhua qhov khoob ntawm qhov chaw tsim khoom tom qab siv cov caj npab los yog hloov cov tuav. Txhua qhov chaw nres tsheb ua haujlwm ntawm nws tus kheej, uas txhais tau hais tias qhov chaw tuaj yeem hloov kho, tig, lossis txawm tias rov ua haujlwm ntawm kev ua haujlwm.

Qhov kev ywj pheej no los ntawm cov kab geometry ua rau kev hloov pauv tuag mus - rau kev xaiv rau tsheb stamping tuag zoo li lub cev vaj huam sib luag, cov lauj kaub roj, thiab cov khoom sib txuas uas xav tau kev sib sib zog nqus sib sib zog nqus los yog txoj hauv kev sib txawv. Cov tshuab hloov pauv kuj tseem siv cov khoom siv tsawg dua rau ib feem vim tsis muaj cov kab nqa khoom txuas nrog cov khoom ua haujlwm, txo cov nqi seem ntawm cov khoom siv - cov khoom siv hnyav. Kev lag luam tawm yog ib txoj hauv kev nyuaj dua tag nrho, feem ntau koom nrog ntau lub xovxwm hauv txoj kab sib koom ua ke, nrog rau feem ntau qeeb lub voj voog nrawm dua li siab - kev ua haujlwm nrawm.

Tuag hom kev sib piv Framework

Txoj cai stamping tuag hom yeej tsis yog cov lus teb thoob ntiaj teb. Nws tshwm sim los ntawm kev sib tshuam ntawm koj qhov geometry, koj qhov kev kwv yees ntim, thiab koj qhov yuav tsum tau ua siab ntev. Kev xaiv kom raug nyob rau theem no tau teeb tsa lub hauv paus rau txhua yam hauv qab no: qhov loj me ntawm cov khoom lag luam, suav nrog kev tshem tawm, thiab chaw nres tsheb - los ntawm - chaw nres tsheb logic uas hloov cov sawb rawg rau hauv qhov chaw tiav.

Core Tuag Cheebtsam thiab Yuav Ua Li Cas Lawv Ua Haujlwm Ua Ke

Xaiv ib tug tuag hom muab rau koj lub architecture. Tab sis architecture tsis muaj kev nkag siab ntawm tus neeg stamping tuag Cheebtsam yog zoo li xaiv lub tsev style yam tsis paub tias kab, kab teeb, thiab pob qij txha ua dab tsi. Yog li dab tsi yog tuag ua los ntawm, functionally? Txhua qhov hlau stamping tuag yog ib qho kev sib dhos ntawm cov khoom sib txuas, txhua tus ua lub luag haujlwm tshwj xeeb hauv kev txiav, tsim, tswj cov khoom, lossis tswj kev sib dhos. Thaum ib feem ua tsis tau lossis tsis tau teev tseg, tag nrho lub cev raug kev txom nyem.

Upper thiab Lower Die Khau Sib Tsoo

Cov khau tuag ua rau cov pob txha pob txha ntawm cov cuab yeej. Cov khau qis nce mus rau lub txaj xovxwm, thaum lub khau sab saud txuas mus rau lub xovxwm ram, tsim kom muaj ib lub thav duab nruj uas txhawb nqa txhua lwm yam hauv qab kev thauj khoom loj heev. Nruab nrab ntawm lawv, qhia pins thiab bushings xyuas kom lub sab sauv thiab sab halves ua ke nrog rov ua tau zoo, feem ntau nyob rau hauv tolerances ntawm 0.0001 nti. Muaj ob txoj hauv kev xaiv: kev sib txhuam- hom pins ncaj nraim rau cov ntawv thov yooj yim, thiab pob-cov kabmob qhia cov pins uas glide rau hauv tawb bearings rau kev sib cais yooj yim dua thiab ua haujlwm ntev dua.

Heel blocks ntxiv lwm txheej ntawm kev ruaj ntseg. Mounted nyob rau sab ntawm lub teeb tuag, lawv nqus lateral thrust generated thaum lub sij hawm tsim kev ua hauj lwm thiab tiv thaiv lub Upper tuag los ntawm hloov sideways nyob rau hauv load. Ua ke, cov khau, phau ntawv qhia pins, thiab pob luj taws ua ib qho kev sib dhos uas ua kom cov punch - rau - tuag kev sau npe sib npaug thoob plaws ntau lab ntawm cov xovxwm.

Punch thiab Tuag Thaiv Kev Sib Raug Zoo

Yog tias cov khau tuag yog cov pob txha, xuas nrig ntaus thiab cov blocks tuag yog txhais tes ua haujlwm tiag tiag ntawm kev xuas nrig ntaus stamping. Lub punch yog cov txiv neej lub caij, feem ntau mounted nyob rau hauv lub Upper tuag. Nws lub qhov ntswg geometry, txawm tias puag ncig, oblong, square, los yog kev cai -profileed, txhais cov kev txiav los yog daim ntawv rau ntawm daim hlau. Raws li cov xovxwm tsav lub punch downward, nws nkag mus rau hauv lub mating kab noj hniav nyob rau hauv lub tuag thaiv hauv qab no.

Lub thaiv tuag muab cov poj niam sib koom ua ke, thiab qhov sib txawv ntawm qhov punch thiab tuag thaiv yog qhov tso cai rau cov khoom sib cais lossis tswj deformation tshwm sim. Qhov sib txawv ntawd tsis yog arbitrary. Nws yog engineered raws li cov khoom siv thiab thickness, thiab nws ncaj qha cuam tshuam rau ntug zoo, burr tsim, thiab cov cuab yeej hnav. Cov nyees khawm tuag, cov khoom siv hloov pauv tau uas ua rau kab tuag thaiv qhov qhib, tsom iav qhov punch profile thiab feem ntau offset loj me ntsis los tsim qhov tsim nyog txiav clearance.

Strippers, Lifters, thiab Pilot Systems

Txiav thiab tsim cov khoom yuav tsis muaj txiaj ntsig yam tsis muaj kev tswj xyuas cov khoom siv. Tom qab ib tug punch pierces los yog ua daim ntawv, elastic rov ua rau cov hlau tuav lub punch nruj nreem. Caij nplooj ntoos hlav-loaded stripper daim hlau daws qhov no los ntawm kev siv lub zog thim rov qab thaum lub sij hawm upstroke, thawb lub strip kom huv si tawm ntawm lub punch thaum tseem clamping cov khoom tiaj tus thaum lub sij hawm txiav stroke los tiv thaiv warping.

Nruab nrab ntawm cov chaw nres tsheb nyob rau hauv ib tug zuj zus tuag, lifters elevates lub strip me ntsis saum toj no tuag nto. Qhov no txo ​​qis kev sib txhuam thaum pub mis, tiv thaiv cov kab nrib pleb los ntawm snagging ntawm qis dua nta, thiab ua kom muaj kev vam meej ntawm qhov tseeb. Pilots, me me precision pins uas nkag mus ua ntej - punched qhov nyob rau hauv sawb, tuav chaw nres tsheb - mus rau - chaw nres tsheb rau npe. Lawv rub lub sawb mus rau hauv kev sib raug zoo ua ntej txhua qhov kev tawm dag zog, tswj kev ua haujlwm zoo - rau -feature raug nyob thoob plaws txhua qhov kev nce qib.

Stamping Tuag Cheebtsam los ntawm Kev Ua Haujlwm

• Txiav Cheebtsam:Punches, tuag nyees khawm, blanking inserts, trimming steels
• Forming Cheebtsam:Khoov punches, kos duab inserts, coining blocks, embossing cov ntsiab lus
• Cov khoom siv tuav cov khoom siv:Stripper daim hlau, stock lifters, feed rails, scrap chutes, slug reliefs
• Alignment Cheebtsam:Qhia pins, qhia bushings, pob luj taws blocks, pilots, dowel pins

Txhua pab pawg ua haujlwm nyob ntawm lwm tus. Alignment Cheebtsam kom txiav thiab tsim cov khoom hauv kev sau npe. Cov khoom siv tuav cov khoom kom ntseeg tau tias lub sawb yog qhov chaw kom raug ua ntej txiav tawm thiab tshem tawm kom zoo tom qab ntawd. Thaum cov kws tsim qauv tsim cov tshuab no ua ib qho kev sib koom ua ke es tsis yog cov khoom sib cais, qhov tshwm sim yog qhov tuag uas khiav ceev ceev, tuav kev ua siab ntev ntev ntev, thiab ua kom yooj yim txij nkawm thaum hnav cov khoom xav tau hloov.

Kev nkag siab tias cov ntsiab lus no cuam tshuam li cas kuj qhia qhov teeb meem tshwm sim. Qhov teeb meem burr tuaj yeem taug qab rov qab rau lub khawm tuag, tab sis nws tuaj yeem yooj yim los ntawm tus pin phau ntawv qhia uas tau tsim kev ua si ntau dhau, hloov lub punch tawm - nruab nrab. Lub hauv paus zoo li ntawd-ua rau kev xav nyob ntawm seb qhov kev tshem tawm ntawm qhov punch thiab tuag thaiv cuam tshuam li cas rau kev txiav, uas yog raws nraim qhov chaw txuas ntxiv ntawm kev tsim cov logic pib.

Tuag Clearance Principles thiab Burr Control

Clearance yog arguably ib qho kev nkag siab yuam kev tshaj plaws nyob rau hauv tag nrho cov txheej txheem tuag. Cov kws ua haujlwm feem ntau nco txog tus lej tsis raug, siv nws thoob plaws ntiaj teb, thiab tom qab ntawd xav paub yog vim li cas lawv cov ntawv hlau stamped muaj qhov tsis sib xws lossis yog vim li cas lawv cov punches hnav ntxov ntxov. Qhov tseeb yog qhov punch-rau- tuag clearance tsis yog tus nqi tas. Nws yog kev sib raug zoo suav nrog uas hloov nrog txhua yam khoom, txhua qhov tuab, thiab txhua qhov kev xav tau zoo.

Yuav ua li cas Clearance cuam tshuam txiav zoo thiab tuag lub neej

Thaum lub punch nqis mus rau hauv qhov qhib tuag, cov ntawv hlau tsis sib cais kom huv si hauv ib qho xwm txheej. Cov ntawv txiav ntug hauv cov cheeb tsam sib txawv, txhua qhov cuam tshuam los ntawm ntau npaum li cas clearance muaj nyob nruab nrab ntawm cov punch thiab tuag txiav npoo. Koj yuav pom plaub thaj tsam ntawm ib qho kev sib tsoo: lub rollover (qhov twg cov khoom raug rub mus rau hauv qhov txiav), shear cheeb tsam (ib tug du, burnished band), lub pob txha tawg (ib tug rougher so nto), thiab burr (ib tug nyias tsa ceg di ncauj nyob rau hauv qab ntug).

Kev tshem tawm kom raug kho cov kab mob tawg uas tshwm sim los ntawm qhov punch edge thiab tuag ntug kom lawv ua tau raws li cov khoom tuab. Thaum kev tshem tawm nruj dhau, cov dav hlau tawg tsis sib xws, yuam kev sib tw thib ob uas ua rau kom muaj zog txiav thiab ua kom nrawm nrawm. Thaum clearance loj dhau lawm, cov ntaub ntawv kua muag es shearing, ua hnyav burrs, ib tug ntxhib fracture cheeb tsam, thiab tsis zoo seem tswj ntawm qhov tiav.

Dhau ntawm ntug zoo, kev tshem tawm ncaj qha cuam tshuam rau cov cuab yeej ua haujlwm ntev. Kev tshawb fawb ntawm punch tooling strain qhia tau hais tias nce kev tshem tawm ntawm ib txwm muaj txiaj ntsig mus rau 11-20% ntawm cov ntaub ntawv tuab tuaj yeem txo qhov kev ntxhov siab ntawm cov khoom siv punch thaum lub sij hawm tho, txuas ntxiv lub neej ua haujlwm yam tsis muaj kev cuam tshuam cov ntug kev siv rau ntau daim ntawv thov.

Clearance xaiv los ntawm cov khoom siv thiab Thickness

Clearance yog ib txwm qhia raws li feem pua ​​ntawm cov khoom thickness ntawm ib sab. Qhov no txhais tau hais tias qhov sib txawv ntawm txhua sab ntawm lub punch txheeb ze rau qhov tuag qhib nplai proportionally nrog tuab npaum li cas koj workpiece yog. Ib qho 10% rau - sab clearance ntawm 1.0 hli Tshuag txhais mus rau 0.1 hli ntawm qhov sib txawv ntawm txhua sab ntawm lub punch.

Dab tsi txiav txim siab qhov feem pua? Material ductility thiab hardness. Softer, ntau cov ntaub ntawv zoo li txhuas shear nrog tsawg zog thiab muaj peev xwm zam nruj clearances. Cov ntaub ntawv nyuaj zoo li siab - lub zog steel tiv thaiv deformation hnyav dua, yuav tsum muaj qhov sib txawv loj dua kom tso cai rau thaj tsam tawg kom nthuav tawm kom raug yam tsis muaj kev siv ntau dhau.

Ntawm no yog qhov uas ntau tus engineers ntsib teeb meem: lawv rub ib tus lej los ntawm kev nco thiab siv nws hla tag nrho lawv cov ntawv hlau stamping tuag. Hauv kev xyaum, txawm tias nyob rau hauv tib txoj kev tuag, qhov sib txawv yuav xav tau qhov sib txawv ntawm qhov feem pua ​​​​nyob ntawm qhov tshwj xeeb geometry, qhov yuav tsum tau ua siab ntev, thiab kev cia siab lub neej. Ib txwm siv cov ntaub ntawv- cov kab kos tshwj xeeb tshem tawm los ntawm cov phau ntawv siv los yog koj tus neeg muab khoom punch cov ntaub ntawv engineering es tsis yog cia siab rau lub neej qub.

Burr Direction Control nyob rau hauv Die Layout

Txhua qhov kev txiav hauv kev ua haujlwm stamping ua ib qho burr ntawm ib sab ntawm cov khoom. Nyob rau hauv precision tuag stamping, engineers tsis tsuas yog sim kom txo qis qhov siab burr. Lawv lub tswv yim taw qhia uas lub ntsej muag ntawm ib feem nqa lub burr raws li kev ua haujlwm thiab kev ua haujlwm hauv qab.

Lub burr ib txwm ua nyob rau sab ntawm cov khoom uas tawm tsam cov punch nkag. Yog hais tias lub punch nkag los ntawm sab saum toj, lub burr tshwm nyob rau hauv qab lub ntsej muag. Qhov no txhais tau hais tias burr kev taw qhia yog tswj los ntawm kev txiav txim siab seb ib tug feature yog txiav los ntawm saum toj los yog hauv qab ntawm lub tuag layout. Rau qhov chaw uas yuav tau txais kev khoov tom ntej, engineers orient burrs mus rau sab hauv ntawm lub vojvoog khoov kom tsis txhob tawg ntawm ntug. Rau cov chaw sib dhos lossis lub ntsej muag kom zoo nkauj, burrs raug coj mus deb ntawm qhov tseem ceeb.

Nyob rau hauv kev vam meej tuag, kev tswj burr kev taw qhia yuav nyuaj dua vim hais tias ntau chaw nres tsheb txiav nta los ntawm txawv orientations. Ua tib zoo strip layout kev npaj ua kom tag nrho cov burrs xaus rau ntawm qhov txaus siab ntawm qhov tiav.

Clearance Guidelines los ntawm cov khoom qeb

Cov kab no sawv cev rau cov ntsiab lus pib dav dav los ntawm kev luam tawm cov cuab yeej engineering cov ntaub ntawv. Qhov tseeb clearance yuav tsum tau validated tiv thaiv koj tej ntaub ntawv pov thawj, ntau lawm ntim hom phiaj, thiab pom zoo ntug qauv. Tooling condition tseem ceeb heev. Raws li cov punches hnav, kev tshem tawm tau zoo nce ntxiv, yog li koj qhov kev teeb tsa thawj zaug yuav tsum suav rau qhov xav tias yuav hnav dhau lub sijhawm tu.

Kev txiav txim siab tshem tawm tsis muaj nyob hauv kev sib cais. Lawv cuam tshuam nrog txhua lwm qhov kev tsim qauv, tshwj xeeb tshaj yog li cas kev ua haujlwm tau ua raws cov chaw nres tsheb. Tus nqi tshem tawm uas tsim cov npoo tau txais txiaj ntsig hauv kev sib cais yuav ua rau muaj kev cuam tshuam ntawm kev sib cais lossis kev sau npe tsis raug thaum ua ke nrog cov kev ua haujlwm uas nyob ib sab, uas yog vim li cas qhov chaw nres tsheb sib txuas lus tsim nyog rau nws txoj kev qhuab qhia.

Progressive Die Station Sequencing Logic

Ib qho kev tuag zuj zus tuaj yeem muaj kaum, nees nkaum, lossis ntau qhov chaw nres tsheb, thiab tseem tsis muaj dab tsi tshwm sim ntawm qhov kev txiav txim uas ua haujlwm tshwm sim. Cov txheej txheem stamping ua raws li kev nruj engineering logic qhov twg txhua qhov chaw nres tsheb nyob ntawm cov ua ntej nws thiab txwv cov tom qab nws. Tau txais qhov tsis ncaj ncees lawm tsis yog qhov tsis yooj yim me. Nws cuam tshuam cov yam ntxwv, rub tawm cov ntawv sau npe, thiab tsim cov khoom seem uas noj rau hauv koj cov kab hauv qab. Qhov no yog qhov chaw stamping tsim cais cov kws paub txog cov cuab yeej cuab tam los ntawm cov uas tseem kawm txoj kev nyuaj.

Kev txiav txim siab ua haujlwm ib ntus thiab chaw nres tsheb suav

Thaum npaj cov cuab yeej ua haujlwm rau kev tuag tshiab, thawj lo lus nug tsis yog "Kuv xav tau dab tsi ua haujlwm?" tab sis theej "dab tsi yuav tsum tshwm sim ua ntej txhawb txhua yam ntxiv?" Cov lus teb yuav luag ib txwm pib nrog tsim cov datums. Pilot qhov yog tho rau ntawm qhov chaw nres tsheb thawj zaug vim tias lawv ua haujlwm raws li qhov chaw siv rau txhua qhov haujlwm tom ntej. Raws li tsimProgressive die manufacturability cai, tho kev ua haujlwm rau kev tsav lub qhov yuav tsum tau ua nyob rau hauv thawj qhov chaw nres tsheb kom ntseeg tau tias kev sau npe raug nyob thoob plaws hauv txoj kev loj hlob.

Carrier strip nta tuaj tom ntej. Cov no yog cov qauv kev sib txuas uas lub cev nqa lub workpiece los ntawm chaw nres tsheb mus rau chaw nres tsheb. Yog tias tsis muaj cov neeg nqa khoom muaj zog tsim tau ntxov, lub sawb tsis muaj qhov rigidity pub kom raug raws li xovxwm quab yuam. Kev ua haujlwm tsis zoo uas txhais tau hais tias tus cab kuj geometry feem ntau ua raws tam sim tom qab tsav tsheb.

Los ntawm qhov ntawd, lub hauv paus ntsiab lus sequencing ntws zoo li no: txiav tiaj tus nta ua ntej, daim ntawv thib ob, qhov kawg. Piercing thiab notching tshwm sim thaum cov khoom tseem tiaj tus vim lub qhov punched rau hauv twb - tsim nto distort unpredictably. Kev tsim cov kev ua haujlwm tau nce los ntawm qhov tsawg kawg nkaus mus rau qhov hnyav tshaj plaws, muab cov khoom siv tswj kev los ntawm lub tiaj tus mus rau qhov kawg geometry. Embossing, yog tias tam sim no, feem ntau ua thaum ntxov los tiv thaiv deformation ntawm lwm yam nta. Blanking, lub lag luam uas cais cov tiav ib feem ntawm cov cab kuj strip, ib txwm tshwm sim ntawm qhov kawg chaw nres tsheb vim hais tias ib feem yuav tsis tau indexed ib zaug nws yog dawb.

Suab yooj yim? Qhov kev sib tw yog qhov tiag tiag muaj kaum ob ntawm cov yam ntxwv nrog cov kev sib raug zoo geometric. Kev tshawb fawb rau hauv cov txheej txheem kev sib txuas ua ke txheeb xyuas ob hom kev txwv tseem ceeb uas tswj hwm qhov kev txiav txim: kev txwv ua ntej, uas hais tias qee yam kev ua haujlwm yuav tsum tshwm sim ua ntej lwm tus raws li cov cai ntawm kev tsim khoom, thiab cov kev txwv nyob ib puag ncig, uas tiv thaiv cov yam ntxwv uas nyob ze dhau los ntawm kev sib tsoo ntawm tib lub chaw nres tsheb kom tsis txhob tsim cov hlau tsis muaj zog.

Sib npaug zog hla chaw nres tsheb

Xav txog qhov kev vam meej tuag qhov twg tag nrho cov haujlwm tho hnyav ua haujlwm sib koom ua ke ntawm ib sab thiab tag nrho cov kev sib sau ua ke tsom mus rau lwm qhov. Yuav ua li cas? Cov xovxwm ram tilts microscopically nyob rau hauv lub sijhawm tsis sib npaug, qhov tuag deflects asymmetrically, thiab cov sawb mus rau sab. Qhov tshwm sim yog kev sau npe tsis raug uas suav nrog txhua qhov mob stroke.
