Stamping Tuag Tsim Kev txiav txim siab uas cais zoo tuag los ntawm seem

Dab tsi Stamping Tuag Tsim tiag tiag xav tau los ntawm Engineers

Txhua qhov chaw stamped dov tawm ib qho xovxwm pib raws li kev txiav txim siab engineering. Qee qhov kev txiav txim siab no ua rau tuag uas khiav rau ntau lab lub voj voog yam tsis muaj xwm txheej. Lwm tus tsim cov khoom kim heev. Qhov txawv tsis tshua muaj nqis los rau hmoov zoo.

Stamping tuag tsim yog kev qhuab qhia engineering ntawm kev tsim cov cuab yeej precision uas hloov cov ntawv tiaj tus hlau mus rau hauv cov khoom tiav los ntawm kev tswj cov yas deformation, ntsuas ib feem geometry, cov khoom coj tus cwj pwm, ntim ntau lawm, thiab kev saib xyuas nkag mus rau hauv ib qho kev sib koom ua ke.

Qhov kev txhais ntawd suab ncaj nraim. Hauv kev xyaum, nws xav tau kev lag luam tawm - tawm ntawm txhua qhov tig.

Stamping Die Design txhais li cas hauv kev xyaum

Thaum kojtsim ib tug stamping tuag, koj tsis tsuas yog ua qauv rau lub punch thiab kab noj hniav. Koj tab tom kwv yees li cas hlau yuav ntws, ncab, thiab lub caij nplooj ntoos hlav rov qab rau hauv lub zog. Koj tab tom suav nyiaj rau thermal expansion thaum lub sij hawm ntev xovxwm khiav, npaj rau cov cuab yeej hnav ntau pua txhiab tus hits, thiab tsim kom muaj kev nkag tau yooj yim kom tus kws tshaj lij tuaj yeem sib pauv cov ntaub qhwv tsis tas yuav disassembled ib nrab ntawm cov cuab yeej.

Precision tooling rau cov ntawv hlau stamping yuav tsum ua kom haum qhov ntev, qhov yuav tsum tau ua kom tiav, thiab lub sij hawm lub sij hawm lub hom phiaj ib txhij. Nco ib qho txawv txav, thiab kev tsim khoom raug kev txom nyem. Ib tug tuag uas tuav kam tab sis khiav qeeb heev raug nqi nyiaj. Tus tuag uas khiav ceev tab sis hnav ua ntej yuav raug nqi ntau dua.

Vim li cas Tsim Kev Txiav Txim Siab Ua Rau Ntau Lawm

Kev tsim tuag zoo tsis yog hais txog kev ua raws li ib qho qauv. Nws yog stamping tuag tsim kev txiav txim siab lub moj khaum qhov twg txhua qhov kev xaiv, los ntawm kev tuag hom mus rau qib steel mus rau tus nqi clearance, cascades mus rau downstream tshwm sim. Xaiv qhov tsis ncaj ncees lawm clearance thiab burrs spike tom qab 50,000 hits. Undersize ib phau ntawv qhia thiab kev sib dhos drifts nyob rau hauv siab - khiav ceev. Hla qhov chaw nres tsheb tsis muaj zog thiab kev hloov pauv engineering yav tom ntej yuav tsum muaj kev tsim kho tshiab.

Kab lus no taug kev los ntawm cov kev xaiv tseem ceeb ib los ntawm ib qho. Txhua ntu ua ntej tackles ib qho kev txiav txim siab tshwj xeeb uas cais qhov tuag ua tau zoo hauv kev tsim khoom los ntawm ib qho kev rov qab mus rau chav cuab yeej, suav nrog kev xaiv cov khoom tuag, cov luag haujlwm ntawm lub luag haujlwm, strip layout logic, clearance lub tswv yim, thiab cov khoom siv xaiv uas txhais tau tias tuag ntev.

Tuag Hom Xaiv raws li Multi-Variable Engineering Decision

Lub stamping tuag uas ua haujlwm zoo kawg nkaus rau 5,000 qhov chaw hauv ib xyoos tuaj yeem dhau los ua lub tog raj kheej ntawm 500,000. Qhov laj thawj yog qhov yooj yim: hom tuag txiav txim siab npaum li cas cov khoom txav mus los ntawm cov xovxwm, muaj pes tsawg txoj haujlwm tshwm sim rau ib qho mob stroke, thiab ntau npaum li cas kev ua haujlwm txhua lub voj voog xav tau. Xaiv qhov zoo architecture tsis yog ib qho kev txiav txim siab catalog. Nws yog ib qho kev sib npaug ntawm cov ntim ntau lawm, ib feem complexity, thiab cov kam rau ua koj daim ntawv thov yuav tsum tau.

Ib leeg -chaw nres tsheb tuag rau qhov yooj yim lossis qis-Volume Parts

Ib leeg- chaw nres tsheb tuag ua ib qho haujlwm rau ib qho kev tawm dag zog: ib qho khoob, tho, khoov, lossis daim ntawv. Koj thauj khoom, xovxwm voj voog, thiab ib qho feature tau tsim. Rau cov qauv, luv- khiav ntau lawm, lossis cov khoom ua haujlwm loj uas lub cev tsis tuaj yeem pub los ntawm cov cuab yeej ua tau zoo, ib qho - chaw nres tsheb tuag ua rau muaj kev nkag siab zoo. Tus nqi cuab yeej nyob qis qis, lub sijhawm ua haujlwm luv luv, thiab cov qauv kev hloov pauv pheej yig los siv.

Compound tuag ntxiv ib txheej ntawm kev sib koom ua ke los ntawm kev ua ob lossis ntau qhov kev ua haujlwm hauv ib qho hlab ntsha tawg, xws li blanking ib sab profile thaum tib lub sijhawm tho qhov hauv. Txoj hauv kev no muab kev ua kom zoo dua qub thiab lub qhov nruj dua- rau - ntug kev sib raug zoo vim tias txhua qhov nta tau tsim nyob rau hauv ib qho xovxwm ntaus, tshem tawm qhov chaw nres tsheb - mus rau - chaw nres tsheb qhov yuam kev. Kev sib xyaw tuag mus ntxiv los ntawm kev sib xyaw txiav thiab tsim kev ua haujlwm hauv ib qho mob stroke, txawm tias lawv ntxiv qhov nyuaj rau cov cuab yeej tsim.

Progressive Dies rau siab -Volume Complex Stampings

Progressive tuag txav ib tug nruam hlau sawb los ntawm ib tug series ntawm chaw nres tsheb, txhua tus ntxiv ib tug feature: ib tug tho qhov no, ib daim ntawv muaj, ib tug trim thaum kawg. Ib feem nyob twj ywm txuas nrog tus cab kuj strip mus txog thaum kawg txiav tawm. Qhov no architecture yog zoo tagnrho rausiab - ntim ntau lawm ntawm complex qhov chawvim nws tshem tawm kev tuav tuav ntawm kev khiav hauj lwm, xa cov sij hawm ceev ceev, thiab tswj cov chaw nres tsheb ceev - mus rau - chaw nres tsheb raug los ntawm kev sau npe tsav tsheb.

Kev lag luam tawm - tawm? Cov cuab yeej ua ntej siab dua thiab siv sij hawm ntev dua. Kev tsim qauv hloov nruab nrab - ntau lawm tuaj yeem kim. Tab sis thaum lub ntim ua kom pom tseeb qhov kev nqis peev, cov kev vam meej tuag xa cov nqi qis tshaj ntawm -ib feem thiab qhov ua tau zoo tshaj plaws.

Xaiv qhov Zoo Tuag Hom Raws li Volume thiab Complexity

Qhov chaw nres tsheb ib leeg tuag vs kev vam meej tuag kev sib piv tsis yog hais txog kev ceev xwb. Nws qhia txog qhov sib txawv tsim kev xav. Ib qho luv luv - khiav tuag ua qhov tseem ceeb ntawm kev hloov pauv thiab cov cuab yeej siv qis. Ib qho kev tuag zuj zus tseem ceeb tshaj qhov kev ua haujlwm ntawm lub voj voog, kev cuam tshuam tus neeg ua haujlwm tsawg, thiab kev txheeb xyuas qhov sib xws thoob plaws ntau lab hits. Ib qho chaw tuag zaum hauv nruab nrab, ua lag luam qee qhov nrawm rau qhov zoo tshaj plaws flatness hauv nruab nrab - ntim cov xwm txheej.

Thaum ntsuam xyuas stamping tuag hom kev xaiv, nug peb lo lus nug: Muaj pes tsawg feem hauv ib xyoos twg koj qhov kev pab cuam xav tau? Muaj pes tsawg tus yam ntxwv tshwj xeeb yog ib feem? Thiab nruj npaum li cas yog koj qhov yuav tsum tau ua siab ntev npaum li cas rau cov xovxwm raug? Cov lus teb sib cuam tshuam. Ib qho geometrically complex ntawm qhov ntim tsawg kuj tseem tuaj yeem ua pov thawj cov cuab yeej ua tau zoo yog tias kev kam rau siab xav tau cov ntawv sau npe sib xws uas tsuas yog siv cov sawb pub noj xwb. Hloov pauv, lub tshuab ntxhua khaub ncaws yooj yim ntawm qhov ntim siab tuaj yeem khiav lag luam feem ntau ntawm cov khoom sib xyaw tuag ntau dua li kev teeb tsa kim dua.

Txhua hom tuag kuj tseem tsim cov kev xav tau sib txawv thiab tsim kev txwv ntawm cov khoom hauv nws, los ntawm cov txheej txheem qhia thiab strippers mus rau cov punches thiab cov nyees khawm tuag uas ua haujlwm tiag tiag.

Stamping Tuag Cheebtsam thiab lawv cov luag haujlwm engineering

Los ntawm sab nraud, stamping tuag zoo li ib qho khoom thaiv ntawm cov hlau. Qhib nws, thiab koj yuav pom kaum ob ntawm cov khoom sib koom ua ke, txhua tus engineered los ua ib txoj haujlwm tshwj xeeb hauv kev quab yuam thiab nrawm. Kev nkag siab tias txhua qhov ua li cas, thiab nws cuam tshuam nrog nws cov neeg nyob ze, yog dab tsi cais cov cuab yeej tsim khoom lag luam uas ntseeg tau los ntawm ib qho uas misfeeds, hnav ntxov ntxov, los yog ua khoom seem.

Xav txog qhov kev vam meej tuag khiav ntawm 400 strokes ib feeb. Txhua feem yuav tsum nrhiav, txiav, daim ntawv, thiab eject cov khoom nyob rau hauv milliseconds, ces rov pib dua rau lub voj voog tom ntej. Ib qho kev sib txuas tsis muaj zog hauv cov saw hlau ntawd, txawm tias nws yog ib qho kev qhia tsis zoo los yog ib lub stripper nrog me ntsis kev mus ncig, cascades rau hauv cov teeb meem zoo thiab tsis tau npaj tseg.

Upper thiab Lower Die Khau Sib Tsoo

Cov khau tuag yog lub hauv paus tsim. Cov khau khiab qis rau ntawm lub txaj xovxwm, thiab cov khau sab saud txuas mus rau lub xovxwm ram. Ua ke, lawv muab lub platform nruj uas txhawb nqa thiab nrhiav txhua lwm yam hauv lub cuab yeej. Cov khoom xaiv tseem ceeb ntawm no: cov hlau cam khwb cia hlau lossis cov hlau forged muab cov tawv tawv uas xav tau los tiv thaiv deflection nyob rau hauv tag nrho cov tonnage. Cov khau tuag uas flexes txawm tias ob peb txhiab ntawm ib nti hauv qab load yuav hloov cov kev tshem tawm thiab tsim cov contours, ua rau qhov tsis sib haum xeeb tom qab mob stroke.

Tuag khau qhia ncej thiab bushing tsim txiav txim siab yuav ua li cas yog lub sab sauv thiab sab halves dlhos thoob plaws hauv xovxwm stroke. Cov ntawv qhia cov lus qhia yog qhov tseeb- cov kab hlau hauv av nias rau hauv ib lub khau, thiab lawv xaub los ntawm kev sib txuam bushings hauv cov khau ntxeev. Pob-cov kabmob bushings txo kev sib txhuam thiab hnav thaum lub sijhawm ua haujlwm siab- nrawm, thaum lub pob zeb bronze ua haujlwm zoo rau qeeb qeeb, hnyav dua -tonnage daim ntawv thov. Qhov kev txiav txim siab tsim qauv tseem ceeb? Ncej txoj kab uas hla thiab ntev yuav tsum phim cov xovxwm tonnage thiab ceev. Cov ntawv qhia tsis zoo tso cai rau kev ua si sab hauv qab sab, uas ua rau nrawm hnav ntawm txhua qhov txiav thiab tsim cov khoom hauv qhov tuag.

Punches, Tuag khawm, thiab txiav cov khoom

Punches thiab tuag nyees khawm yog cov khoom ua haujlwm uas dawb paug, tho, thais, thiab luas cov khoom. Lub punch thawb cov ntawv hlau los ntawm lub pob tuag qhib, shearing nws raws cov ntug txiav. Txhua lub punch yog tuav nyob rau hauv ib lub phaj retainer thiab txhawb los ntawm ib tug hardened backup phaj uas faib cuam tshuam quab yuam thiab tiv thaiv lub punch los ntawm kev tsav tsheb mus rau hauv lub softer lub khau.

Cov nyees khawm tuag, qee zaum hu ua tuag inserts, zaum hauv precision-machined hnab ris hauv qab tuag. Lawv cov geometry txhais cov npoo tiav ntawm qhov txiav. Cov kws tsim khoom xaiv cov khoom siv khawm thiab cov txheej txheem raws li cov ntawv hlau raug stamped thiab qhov xav tau ntau lawm ntim. Lub pob tuag rau cov hlau me me ntawm 100,000 lub voj voog tuaj yeem siv D2 cov cuab yeej hlau, thaum ib qho rau cov hlau tsis xeb ntawm ib lab lub voj voog tuaj yeem ua pov thawj rau cov carbide ntxig.

Forming inserts kov dabtsi yog khoov, npib, thiab embossing kev ua haujlwm. Tsis zoo li kev txiav cov khoom, lawv zoo li cov khoom yam tsis tau txiav nws. Lawv cov radii thiab nto tiav ncaj qha cuam tshuam rau qhov zoo: ib qho ntxhib lossis chipped ua lub vojvoog tawm cov cim pov thawj thiab qhia txog kev ntxhov siab nyob rau hauv ib feem.

Nov yog yuav ua li cas cov pab pawg ua haujlwm tseem ceeb tawg:

• Txiav Cheebtsam:Punches, tuag nyees khawm, trim steels, notching inserts
• Forming Cheebtsam:Bending inserts, coining blocks, embossing pads, kos rings
• Cov ntsiab lus qhia:Qhia posts, bushings, heel blocks, pob taws daim hlau
• Stripping thiab tswj cov khoom:Stripper daim hlau, siab pads, lifter rails, pilots, springs

Lifters, Strippers, thiab cov khoom tswj cov khoom

Stripper thiab lifter tsim rau stamping tuag yog qhov twg ntau inexperienced engineers dawm. Lub phaj stripper ua haujlwm ob txoj haujlwm: nws tuav lub sawb tiaj tus tiv thaiv qhov chaw tuag thaum txiav thiab tsim, thiab nws strips cov khoom tawm ntawm cov punches ntawm upstroke. Tsis txaus stripper siab cia lub sawb nqa nrog lub punch, ua rau misfeeds thiab slug rub. Lub siab ntau dhau ua rau cov khoom siv los yog txwv tsis pub txav mus los.

Stock lifters tsa lub sawb me ntsis saum qhov chaw tuag thaum pub mis. Qhov no txo ​​cov kev sib txhuam, tiv thaiv cov sawb los ntawm kev ntes ntawm cov khoom seem tuag, thiab tso cai rau cov qauv tsim kom tshem tawm cov teeb meem thaum lub sawb nce ntxiv. Lifter qhov siab tsis yog arbitrary. Teem nws qis dhau, thiab nqes mus - tsim cov yam ntxwv rub rau ntawm qhov chaw tuag. Teem nws siab dhau lawm, thiab lub strip yuav tsis ruaj khov, thaws los yog skewing thaum lub sij hawm siab - pub mis ceev.

Cov kws tsav dav hlau yog qhov tseeb- cov pins hauv av uas nkag mus rau hauv qhov uas tau tho yav dhau los hauv lub sawb kom lub cev rov ua haujlwm ua ntej txhua qhov kev txiav lossis kev ua haujlwm tshwm sim. Yuav ua li cas tsav txoj hauj lwm cuam tshuam rau ib feem ntawm kev sau npe yog ncaj qha: cov kws tsav dav hlau kho cov khoom me me uas tsis muaj nyob rau hauv ib qho coil -feem system, rov pib dua lub sawb mus rau nws qhov chaw muaj tseeb txhua qhov mob stroke. Raws liMetalForming Magazine, pilots yuav tsum me me nrog 0.0005 mus rau 0.001-nti clearance mus rau qhov pilot qhov, nyob ntawm seb yam khoom thiab thickness. Lawv qhov ntev yuav tsum tau ua tib zoo calibration ib yam nkaus: ntev txaus los koom ua ntej lwm yam punches hu rau lub sawb, tab sis luv txaus kom tsis txhob khi los yog rub lub strip upward thaum qhib tuag.

Springs thiab nitrogen gas cylinders zog lub stripper phaj, siab pads, thiab lifters. Coil springs muab kev yooj yim thiab tus nqi qis rau lub teeb- daim ntawv thov. Nitrogen gas springs xa cov quab yuam ntau dua nyob rau hauv ib lub pob compact thiab tuav lub siab zoo ib yam thoob plaws hauv lawv cov hlab ntsha, ua rau lawv tus qauv kev xaiv rau siab - ceev ceev ceev tuag. Kev xaiv lub caij nplooj ntoos hlav tsis ncaj ncees tshwm sim sai: qhov tsis sib haum xeeb ntawm kev quab yuam ua rau slug rub, thaum tsis muaj zog lifter springs cia lub strip sag thiab misfeed.

Ob peb qhov yuam kev tsim qauv ua rau muaj teeb meem loj heev hauv kev tsim khoom:

• Undersized phau ntawv qhia posts:Cia cov tuag halves hloov mus rau sab thrust, nce clearance ntawm ib sab thiab txo nws ntawm lwm yam. Qhov tshwm sim yog qhov tsis sib xws burr tsim thiab nrawm hnav.
• Tsis txaus stripper mus ncig teb chaws:Yog tias tus stripper tsis tuaj yeem ncua deb txaus los thawb lub sawb tawm ntawm qhov ntev tshaj plaws, cov khoom siv thiab cov hlab ntsha tom ntej yuav tsoo nws, ua rau ob qho tib si thiab cov cuab yeej puas.
• Tsis zoo pilot placement:Nrhiav cov kws tsav dav hlau deb dhau los ntawm cov yam ntxwv tseem ceeb txo lawv lub peev xwm los kho cov ntawv sau npe yuam kev uas qhov tseeb tseem ceeb tshaj plaws. Muab cov kws tsav dav hlau nyob ze ntawm qhov chaw nres tsheb nrog nruj nruj.
• Mismatched caij nplooj ntoos hlav zog:Tsis sib npaug stripper siab thoob plaws qhov dav dav ua rau lub sawb qaij, ua rau ib qho -sided punch hnav thiab tsis sib xws ntug zoo.

Txhua feem kev txiav txim siab pub rau pem hauv ntej. Kev taw qhia ncej rigidity cuam tshuam rau cov punch-rau- kev sib dhos tuag, uas txiav txim siab ntev npaum li cas cov npoo txiav kom ntse. Stripper tsim tswj seb cov slugs khiav tawm huv si los yog rub rov qab rau hauv qhov tuag. Lifter qhov siab txiav txim seb lub sawb zoo li cas los yog khi thaum lub sijhawm ua haujlwm siab -. Cov kev sib cuam tshuam no piav qhia tias vim li cas kev xaiv cov khoom tsis yog ib txoj kab - kev tawm dag zog. Nws yog ib qho teeb meem engineering uas qhov tsis muaj zog tshaj plaws teeb tsa lub qab nthab rau tag nrho cov cuab yeej ua haujlwm.

Tau txais cov qauv tsim txoj cai txhais tau hais tias cov neeg tuag ua haujlwm tau zoo thiab tswj xyuas qhov zoo tshaj qhov kev sib tw ntev. Tab sis cov khoom ib leeg tsis txhais hais tias kev vam meej. Cov kab ke uas cov khoom siv no ua rau ntawm lub sawb, thiab yuav ua li cas lub sawb tau nteg tawm thoob plaws cov chaw nres tsheb, txiav txim siab seb lub cuab yeej puas tuaj yeem tsim cov qauv geometry yam tsis muaj kev cuam tshuam.

Txhais Tshooj Geometry rau hauv Sawb Layout Kev Txiav Txim

Koj muaj tus qauv ua tiav ntawm qhov screen. Nws muaj qhov, khoov, ib qho emboss, tej zaum ib tug kos feature. Cov lus nug txhua tus neeg tsim qauv tuag tom ntej yog kev dag ntxias yooj yim: qhov 3D zoo li no nthuav tawm rov qab rau hauv ib lub tiaj tiaj, thiab qhov kev txiav txim li cas cov yam ntxwv no tau tsim los ntawm chaw nres tsheb? Cov lus nug ntawd yog cov txheej txheem kev tsim cov txheej txheem tuag sawb, thiab nws yog ib qho kev txiav txim siab uas xauv cov khoom siv, suav chaw nres tsheb, ntev ntev, thiab kev tsim ua ntej yuav raug txiav.

Ib tug strip layout tsis yog ib tug formality. Nws yog kev lag luam thiab cov txheej txheem pob txha ntawm tag nrho cov cuab yeej. Tau txais nws txoj cai, thiab cov tuag khiav nrawm nrog cov seem tsawg. Tau txais nws tsis ncaj ncees lawm, thiab koj tab tom tawm tsam strip instability, seem drift, thiab cov khoom pov tseg rau lub neej ntawm qhov kev pab cuam.

Nyeem Tshooj Geometry kom txiav txim siab ua ntu zus

Thawj kauj ruam yog kawm txog qhov geometry thiab lub hlwb ua haujlwm rov qab los ntawm cov duab tiav mus rau lub tiaj tiaj. Cov yam ntxwv twg xav tau cov khoom siv los ncab lossis compress? Dab tsi yog khoov yooj yim uas tuaj yeem tshwm sim hauv ib qho kev ntaus? Cov qhov twg ua haujlwm li datum rau qhov ntev ntawm cov dej ntws?

Qhov kev tshuaj ntsuam no tsav cov cai tseem ceeb ntawm chaw nres tsheb sib txuas rau kev nce qib tuag stamping: tho ua ntej koj tsim. Qhov thiab cov qhov uas tsim nyob rau hauv cov ntaub ntawv tiaj tus tuav lawv txoj hauj lwm kom raug vim tsis muaj deformation tom qab tau txav cov hlau nyob ib puag ncig. Yog tias koj tsim ib lub flange ua ntej thiab tom qab ntawd sim tho lub qhov hauv nws, cov khoom twb ua haujlwm lawm - tawv, hloov, thiab qhia qhov tsis paub meej ntawm qhov chaw. Lub qhov yuav ntws los ntawm kev luam tawm.

Kos qhov tob, cov khoom thickness, thiab ductility txiav txim seb lub feature tuaj yeem ua tiav hauv ib qho chaw nres tsheb lossis yuav tsum tau ua nyob rau ntau qhov hits. Ib tug ntiav emboss nyob rau hauv mos aluminium tej zaum yuav ua kom huv si nyob rau hauv ib tug mob stroke. Tib qhov tob hauv stainless hlau tuaj yeem tawg yog tias sim tag nrho ib zaug, xav tau ob lossis peb qhov kev txhim kho txuas ntxiv nrog kev ntxhov siab nruab nrab. Suab complex? Nws boils mus nug: cov khoom puas muaj txaus ductility ntxiv tom qab txhua qhov kev ua haujlwm kom muaj sia nyob tom ntej yam tsis muaj kua muag lossis wrinkling?

Lub logic forming ib ntus feem ntau ua raws li cov qauv no:

• Chaw nres tsheb 1-2:Pilot qhov thiab datum nta pierced nyob rau hauv flat strip
• Chaw nres tsheb 3-4:Ntxiv piercing, notching, thiab carrier trimming
• Chaw nres tsheb 5-6:Progressive forming operations (pre-khoov, kawg khoov, los yog staged draws)
• Chaw nres tsheb 7+:Thaum kawg trim, npib rau qhov tseem ceeb qhov ntev, thiab txiav tawm

Cov kab ke no khaws cia qhov tseeb qhov tseeb vim qhov chaw qhov chaw tseem ceeb tau tsim los ua ntej, thaum lub sawb tseem tiaj tus thiab txhawb nqa tag nrho. Kev tsim cov haujlwm tshwm sim tom qab, tom qab tag nrho cov ntaub ntawv txiav raug kaw hauv.

Optimizing siv cov khoom siv nyob rau hauv Strip Layout

Cov khoom siv feem ntau yog tus nqi rov ua dua loj tshaj plaws hauv kev ua haujlwm stamping, tshwj xeeb tshaj yog rau cov hlau tsis muaj steel, tooj liab alloys, lossis ua ntej-plated Tshuag. Yuav ua li cas txhawm rau txhim kho kev siv cov khoom siv hauv stamping los ntawm peb qhov sib txawv: ib feem kev taw qhia ntawm lub sawb, lub tswv yim zes, thiab kev nce qib.

Part orientation yog qhov twg grain kev taw qhia thiab zes nyob rau hauv strip layout intersect. Cov ntawv hlau muaj cov kev taw qhia dov los ntawm lub zeb, thiab bending perpendicular rau cov nplej ua kom huv si, muaj zog khoov nrog tsawg dua springback. Khoov thaum uas tig mus rau cov nplej muaj kev pheej hmoo tawg raws cov quav, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv nyuaj los yog nruj khoov radii. Yog li tus tsim qauv qhia txog qhov tseem ceeb ntawm kev khoov hla cov nplej, txawm tias qhov no txhais tau tias me ntsis ua haujlwm zes.

Qee lub sij hawm qhov zoo tshaj plaws kev coj noj coj ua thiab cov khoom siv feem ntau -kev ua haujlwm zoo ntawm kev sib tsoo. Xav txog ib qho L- zoo li ib feem uas zes kom nruj thaum tig 30 degrees ntawm lub sawb, tab sis lub kaum sab xis ua rau qhov khoov tseem ceeb sib npaug rau cov nplej. Koj yuav tsum tau txi qee cov khoom txuag kom tsis txhob tawg hauv kev tsim khoom. Qhov no yog qhov kev txiav txim hu, tsis yog ib qho qauv, thiab cov neeg tsim qauv paub txog qhov ntsuas tus nqi ntawm cov khoom siv ntxiv rau tus nqi ntawm qhov tsis lees paub.

Raws li cov qauv tsim qauv tsim qauv, kev lag luam benchmark lub hom phiaj tsawg kawg yog 75% kev siv cov khoom siv. Ua kom tiav qhov no yuav tsum tau ceev faj tswj ntawm ntau qhov ntev:

• Choj dav:Cov khoom siv sab laug ntawm qhov uas nyob ib sab thiab nruab nrab ntawm ib feem ntug thiab strip ntug. Ib qho kev qhia dav dav yog 1.25 mus rau 1.5 npaug ntawm cov khoom thickness raws li tus choj yam tsawg kawg nkaus. Nqaim dhau thiab cov pob txha pob txha kua muag los yog jams tuag. Dav dav heev thiab koj nkim khoom txhua txhua stroke.
• Progression suab:Qhov kev ncua deb ntawm txoj hlua mus rau ib qho mob stroke. Qhov no sib npaug ntawm qhov ntev ntawm qhov kev coj noj coj ua ntxiv rau ib tus choj dav. Lub suab luv luv txhais tau hais tias cov khoom siv tsawg dua ib feem, tab sis nws kuj txhais tau tias cov yam ntxwv nyob ze ua ke, uas tuaj yeem ua rau cov cuab yeej sib tsoo thiab txo cov zog tuag.
• Sawb dav:Qhov dav ntxiv rau ob lub ntug txuas ntxiv, ntxiv rau cov khoom nqa khoom yog siv cov khoom thauj sab nraud. Cov strips dav dav kom haum rau qhov loj dua tab sis txo cov kab uas koj tuaj yeem hlais los ntawm tus tswv coil.

Rau qhov tsis xwm yeem zoo li qhov, angular nesting, qhov twg ib feem yog tilted ntawm lub sawb, tuaj yeem rov qab tau cov khoom tseem ceeb. Ib feem uas nkim 30% ntawm cov sawb nyob rau hauv ib tug ncaj orientation yuav nkim tsuas yog 20% ​​thaum qaij 15 degrees. Kev lag luam tawm -tawm yog qhov nyuaj tuag geometry thiab muaj peev xwm tsis sib npaug ntawm kev txiav, tab sis rau cov ntaub ntawv kim, cov nyiaj khaws cia ua pov thawj cov cuab yeej ntxiv nyuaj.

Chaw Nres Nkoj Sequencing Logic los khaws Dimensional Accuracy

Chaw nres tsheb sequencing yog ntau tshaj li tsuas yog xaj kev ua haujlwm raws sijhawm. Nws yog hais txog kev tswj hwm lub zog, tswj cov hlua khi, thiab khaws cia datum kev ncaj ncees los ntawm thawj qhov chaw mus txog qhov kawg.

Ib qho kev ua yuam kev ntau tshaj plaws uas tsis tshua paub txog cov neeg tsim qauv ua yog muab cov kev txiav hnyav uas nyob ib sab ntawm cov chaw tsim khoom tsim. Thaum ib tug loj blanking punch shear los ntawm cov khoom, nws xa ib tug shock yoj los ntawm lub sawb. Yog hais tias lub chaw nres tsheb tom ntej no tab tom sim tuav lub nruj - daim ntawv kam rau ua los yog ib qho emboss ntiav, qhov kev vibration tuaj yeem hloov lub sawb tawm ntawm nws cov neeg tsav tsheb los yog cuam tshuam qhov kev tsim ib feem. Kev kho yog ncaj nraim: ntxig ib qho chaw nres tsheb ntawm qhov hnyav txiav thiab cov ntaub ntawv precision. Idle chaw nres tsheb ntxiv qhov ntev tuag, tab sis lawv cais cov loads poob siab thiab muab qhov chaw rau koj rau yav tom ntej kev hloov pauv engineering yam tsis tau tsim kho tag nrho cov cuab yeej.

Carrier strip tsim kev sib txuas ncaj qha rau hauv kev txiav txim siab sequencing. Cov neeg nqa khoom, qee zaum hu ua lub vev xaib, yog cov khoom siv lub cev thauj khoom los ntawm kev tuag. Nws qhov dav yuav tsum yog tsawg kawg yog ob npaug ntawm cov khoom tuab raws li cov txheej txheem tsim kev tuag, thiab cov tuag loj dua yuav xav tau cov neeg nqa khoom dav dua los tiv thaiv buckling hauv qab pub zog. Yog hais tias ib feem yuav tsum tau downward cov ntaub ntawv, tus cab kuj xav tau txaus flex, qee zaum ua tiav nrog stretch web designs, cia cov khoom kos tsis rub lub strip tawm suab.

Kev quab yuam faib thoob plaws lub sawb kuj xav tau kev saib xyuas. Thaum txiav thiab tsim cov quab yuam tsis sib npaug ntawm sab laug- mus rau - sab xis, lub sawb tuaj yeem tig los yog hloov mus rau tom qab thaum lub sijhawm nias. Cov kws tshaj lij tsim qauv faib cov kev ua haujlwm hnyav symmetrically qhov twg ua tau, lossis ntxiv qhov sib npaug ntawm qhov seem kom sib npaug. Kev tsis quav ntsej qhov no ua rau ib qho -sab tuag hnav thiab kev ua kom zoo sib xws ntawm kev ua haujlwm ntev.

Lub tswv yim kev muaj tiag yog tias strip layout yog rov ua dua. Koj yuav tsis tshua ntsia qhov kev pom zoo rau thawj zaug. Cov neeg tsim qauv feem ntau tsim peb lossis plaub lub tswv yim tsim qauv, ntsuas txhua qhov kev ua haujlwm ntawm cov khoom siv, suav chaw nres tsheb, sib npaug, thiab kev saib xyuas kev nkag mus ua ntej xaiv qhov tsim kawg. CAE simulation accelerates tus txheej txheem no los ntawm kev kwv yees cov khoom thinning, springback, thiab tsim cov kev txwv zoo, tab sis lub hauv paus logic, pierce ua ntej, daim ntawv tom qab, sib npaug zog, tiv thaiv datums, tseem zoo ib yam txawm hais tias koj yog sketch rau ntawm daim ntawv los yog khiav finite element tsom xam.

Nrog rau txoj kev teeb pom kev zoo, txhua qhov chaw nres tsheb ua haujlwm raug kaw. Tab sis qhov zoo ntawm cov kev ua haujlwm, txawm tias kev txiav yog huv los yog ragged, txawm tias cov npoo yog du los yog burred, nyob ntawm qhov sib txawv uas nyob hauv txhua qhov chaw nres tsheb: qhov clearance ntawm punch thiab tuag.

Clearance Calculations thiab Tolerance Specifications

Clearance yog qhov sib txawv ntawm lub punch thiab tuag khawm, ntsuas ib sab. Nws zoo li ib tus lej uas koj saib hauv daim ntawv qhia thiab txav mus. Nyob rau hauv kev muaj tiag, xuas nrig ntaus kom tuag clearance xam los ntawm cov ntaub ntawv hom, thickness, thiab kev khiav hauj lwm yog ib qho ntawm feem kev txiav txim siab nyob rau hauv stamping tuag tsim, thiab ib qho ntawm feem ntau oversimplified.

Ntau lub khw muag khoom ua ntej rau daim pam 10% ntawm cov khoom tuab rau txhua txoj haujlwm. Raws li stamping kev lag luam qub tub rog Art Hedrick taw tes tawm hauvMetalForming Magazine, qhov 10% txoj cai no tau tsim los thaum feem ntau cov khoom stamped yog tsawg- carbon steel. Cov ntaub ntawv niaj hnub, tshwj xeeb tshaj yog siab heev - lub zog steels thiab aluminium alloys, coj txawv txawv thaum lub sij hawm shearing thiab feem ntau xav tau ntau yam clearance qhov tseem ceeb. Siv cov kev tshem tawm tsis ncaj ncees txhais tau tias cov cuab yeej siv nrawm nrawm, cov ntug tsis zoo, thiab kev txiav ntau dua, txhua yam teeb meem uas sib xyaw ntau pua txhiab tus xovxwm strokes.

Yuav Ua Li Cas Cov Khoom Siv Khoom Txiav Txim Siab Tshaj Tawm

Thaum lub punch nqis mus rau hauv cov ntawv hlau, cov khoom siv tsis yog cais. Nws thawj zaug deforms plastically, tsim ib qho chaw hlawv, ci ntsa iab extruded band ntawm ntug txiav. Thaum muaj kev ntxhov siab dhau ntawm cov khoom siv lub zog tensile, tawg pib los ntawm ob qho tib si punch edge thiab tuag ntug ib txhij. Yog hais tias clearance yog lawm, ob txoj kab tawg tau ua kom huv hauv nruab nrab ntawm daim ntawv tuab. Yog tias kev tshem tawm tsis ncaj ncees lawm, lawv tsis sib xws, ua rau theem nrab shear, ragged npoo, lossis ntau burr.

Qhov sib txawv tseem ceeb ntawm no yog kev sib raug zoo ntawm cov khoom siv lub zog tawm los thiab nws lub zog tensile. Tsawg- carbon steel muaj lub zog tensile kwv yees li ob npaug ntawm nws cov txiaj ntsig tawm los, txhais tau tias cov khoom deforms loj heev ua ntej fracturing. Qhov no ua rau cov classic ib qho -thib peb shear, ob-feem peb tawg piv uas 10% txoj cai tau tsim nyob ib ncig ntawm. High-lub zog steels, los ntawm qhov sib piv, muaj cov txiaj ntsig zoo dua rau lawv lub zog tensile. Tsawg heev deformation tshwm sim ua ntej tawg pib, uas txhais tau hais tias tsawg clearance yog feem ntau tsim nyog los tuav ib tug huv si ntug.

Ductility plays lub luag haujlwm tseem ceeb sib npaug. Kev tshawb fawb luam tawm los ntawmTus Fabricatorqhia tau hais tias cov ntaub ntawv uas muaj ductility siab, tsis tshua muaj zog yield zog, thiab homogeneity tsim zoo sheared ntug zoo thiab ntev lub cuab tam lub neej. Raws li ductility txo qis, thaj tsam puas tsuaj dominates ntug txiav, thiab lub qhov rais ntawm qhov pom tau pom tau nqaim. Rau cov aluminium mos, koj tuaj yeem them taus me ntsis ntxiv vim tias cov khoom ntws ua ntej tawg. Rau lub caij nplooj ntoos hlav steel los yog DP980, precision yuav yog ib qho tseem ceeb vim hais tias cov khoom tawg yuav luag tam sim ntawd.

Ntawm no yog yuav ua li cas stamping tuag clearance rau stainless hlau vs txhuas thiab lwm yam khoom siv feem ntau lov:

Cov kab no ua cov ntsiab lus pib. Koj lub tuam txhab cov qauv, cov qib alloy tshwj xeeb, thiab cov kev xav tau zoo rau qhov ua tiav tuaj yeem hloov cov txiaj ntsig no. Ib txwm siv tau tawm tsam engineering phau ntawv qhia thiab kho raws li cov txiaj ntsig sim.

Clearance Kho kom haum rau kev ua haujlwm sib txawv

Kev tshem tawm tsis yog ib tus lej rau txhua qhov chaw nres tsheb hauv qhov tuag. Blanking thiab tho, thaum mechanically zoo sib xws, yuav tsum tau sib txawv mus kom ze vim hais tias ntawm cov khoom yog cov tiav ib feem.

Hauv blanking, qhov khoob uas ntog los ntawm qhov qhib qhov tuag yog ib feem. Koj xav tau qhov huv tshaj plaws ntawm cov khoom ntawd, yog li kev tshem tawm yog siv los ntawm kev ua kom lub punch me dua qhov qhib tuag. Qhov qhib qhov tuag sib npaug rau qhov nominal qhov ntev, thiab cov punch yog undersized los ntawm qhov clearance tus nqi ib sab. Hauv kev tho, lub qhov hauv lub sawb yog qhov tshwj xeeb uas koj nyiam. Lub punch sib phim lub qhov nominal txoj kab uas hla, thiab lub pob tuag yog oversized los ntawm tus nqi clearance. Tsis meej pem ob daim ntawv thov no yog ib qho kev ua haujlwm ntxov- ua haujlwm yuam kev uas ua rau muaj qhov tsis txaus siab ua ntej koj txawm txheeb xyuas qhov zoo.

Kev tsim ua haujlwm ntxiv lwm txheej. Thaum lub chaw nres tsheb ua haujlwm dabtsi yog khoov lossis kos duab es tsis yog txiav ib qho, lub punch-rau- qhov sib txawv tuag tsis yog qhov kev txiav txim siab txiav. Nws yog cov khoom siv - ntws qhov sib txawv, feem ntau teem rau cov khoom tuab ntxiv rau 5-10% tso cai rau cov ntawv xaub los ntawm qhov tsis muaj qhov sib txawv ntau dhau los yog qhov sib txawv. nruj heev thiab cov khoom galls tawm tsam qhov tuag nto. Heev xoob thiab wrinkles tsim.

Yuav ua li cas thaum clearance tsis ncaj ncees lawm? Cov txiaj ntsig sib txawv los ntawm kev coj ua:

• Kev tshem tawm tsis txaus:Kev txiav quab yuam ntau dua, kev poob siab dua ntawm cov xovxwm, cov hlua khi ob sab ntawm cov ntug txiav (ib qho ntxhib, ob npaug -txiav tsos), kev tsim hluav taws xob ntau dhau, thiab nrawm nrawm. Cov kab tawg ntawm cov punch thiab tuag nco ib leeg, xav tau cov khoom siv ntxiv deformation kom tiav qhov txiav.
• Kev tshem tawm ntau dhau:Loj dua rollover cheeb tsam, siab burrs, ntau cov khoom rub- cia rau ntawm qhov tuag, thiab txo cov ntug ncaj. Cov khoom tseem tuaj yeem ua tau raws li qhov ntev ntev tab sis ua tsis tiav qhov kev xav tau zoo. Burr qhov siab loj hlob proportionally nrog nce clearance, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ductile.

Anisotropy ntxiv ib qho teeb meem me me. Raws li tau sau tseg hauv kev tshawb fawb los ntawm Oakland University luam tawm nyob rau hauv Tus Fabricator, cov kab sib txawv ntawm cov kab sib txawv ntawm qhov sib txawv ntawm cov kev taw qhia dov ua rau sib txawv sheared ntug nta, txawm tias zoo tib yam clearances. Ib qho kev sib txuas mus rau qhov kev taw qhia dov tuaj yeem pom qhov sib txawv burr qhov siab dua li ib qho kev txiav hauv qhov kev taw qhia. Rau qhov chaw uas muaj qhov tseem ceeb ntawm ntug kev, cov neeg tsim qauv yuav tsum tau hais kom meej meej sib txawv rau kev txiav khiav hauv cov kev taw qhia sib txawv ntawm cov nplej.

Tolerance Stack-Up and It Effects of Part Quality

Kev teeb tsa txoj kev tshem tawm tsuas yog qhov tseem ceeb yog tias tus neeg tuag tuaj yeem tuav nws mus tas li hauv nws lub neej ua haujlwm. Qhov no yog qhov uas kam rau ua pawg- nce kev tsom xam hauv kev tsim tuag yog qhov tseem ceeb. Txhua yam khoom nyob rau hauv qhov tuag, lub punch, tuag khawm, lub hnab ntim retainer, cov ntawv qhia, cov khau tuag, pab txhawb nws tus kheej qhov sib txawv. Cov kev hloov pauv ntawm tus kheej sib xyaw ua ke hauv lub rooj sib txoos zaum kawg.

Xav txog tej yam yooj yim piercing chaw nres tsheb. Lub punch txoj kab uas hla muaj ib tug kam rau ua. Tuag khawm bore muaj ib tug kam rau ua. Lub hnab ntim lub hnab ntim khoom uas nrhiav lub khawm tuag muaj qhov kam rau ua. Cov txheej txheem qhia uas ua kom cov khau sab saud thiab qis dua muaj qhov ua siab ntev. Muab tag nrho cov no tso rau ntawm lawv qhov phem tshaj - cov ntaub ntawv txwv, thiab kev tshem tawm cov ntaub ntawv tau txais txiaj ntsig zoo tuaj yeem txawv ntawm qhov uas tus tsim qauv npaj.

Muaj ob txoj hauv kev los txheeb xyuas seb cov kev kam rau siab ua ke li cas:

• Qhov phem tshaj - case (arthmetic) tsom xam:Ntxiv tag nrho cov txiaj ntsig siab tshaj plaws kom pom qhov hloov pauv loj tshaj plaws. Qhov no tau lees tias txhua qhov kev sib dhos yuav ua haujlwm, tab sis nws yuav tsum nruj heev rau tus kheej tivthaiv, uas ua rau tus nqi machining nce.
• Kev txheeb xyuas (RSS):Siv cov hauv paus-sum-square xam piv txwv tias tsis yog tag nrho cov khoom yuav nyob ib txhij zaum ntawm lawv qhov kev txwv phem tshaj plaws. Txoj kev no tso cai rau me ntsis looser tus neeg tolerances thaum tswj kev sib dhos ua haujlwm hauv feem ntau ntawm cov neeg mob, feem ntau 99.7% lossis zoo dua.

Txoj cai ntawm tus ntiv tes xoo rau cov neeg tsim khoom tuag: kev tiv thaiv kev tuag yuav tsum tau teev tseg ntawm kwv yees li ntawm ib -thib peb mus rau ib qho -quarter ntawm qhov kam rau ua lawv tswj. Yog hais tias lub qhov nyob ntawm qhov ua tiav yog ib qho kev kam rau siab +/- 0.05 mm, lub punch thiab tuag khawm uas tsim lub qhov yuav tsum tau positional raug nyob rau hauv lub +/-0.012 mus rau +/-0.015 mm. Qhov no suab xav tau, tab sis niaj hnub xaim EDM thiab jig sib tsoo ua tiav cov qib no niaj hnub.

Qhov twg engineers feem ntau underestimate pawg -up yog nyob rau hauv phau ntawv qhia system. Cov khau tuag nrog cov lus qhia ncej bores tuav +/-0.005 mm thiab bushings nrog +/-0.005 mm sab hauv clearance tsim +/-0.010 mm ntawm tej zaum kev hloov pauv ua ntej koj txawm xav txog thermal expansion thaum lub sij hawm ntau lawm. Qhov kev hloov pauv ncaj qha ntxiv rau lossis rho tawm ntawm koj qhov kev txiav tawm. Nyob rau hauv daim ntawv thov nyias nyias qhov twg tag nrho clearance ib sab tej zaum yuav yog 0.05 hli, ib tug 0.010 hli kev taw qhia system hloov sawv cev rau ib tug 20% ​​variation nyob rau hauv zoo clearance, ntau tshaj li txaus los tsim pom burr txawv ntawm ib sab ntawm ib tug txiav mus rau lwm yam.

Kub ua ke qhov teeb meem. Thaum nruam siab - khiav ceev, cov khoom tuag ua kom sov thiab nthuav dav. Ib tug hlau tuag khau khiav 10 degrees Celsius saum toj no ambient expands roughly 0.012 mm rau 100 mm ntawm qhov ntev. Tshaj 500 hli tuag, uas yog 0.06 hli ntawm kev loj hlob, uas tuaj yeem hloov kev sib raug zoo ntawm cov chaw nres tsheb ntawm qhov kawg ntawm lub cuab yeej. Designers account rau qhov no los ntawm kev qhia cov ntaub ntawv nrog qis thermal expansion coefficients rau cov khoom tseem ceeb, los yog los ntawm kev tsim me ntsis nyiaj rau hauv lub hauv paus clearance specification.

Yuav ua li cas clearance cuam tshuam burr thiab ntug zoo tuaj puv lub voj voog ntawm no. Koj tuaj yeem xam qhov feem pua ​​​​ntawm kev tshem tawm zoo tshaj plaws rau koj cov khoom siv thiab cov tuab, tab sis yog tias koj qhov kev kam rau ua pawg - tso cai rau qhov kev tshem tawm mus rau 30% thaum lub sijhawm tsim khoom, ntug zoo yuav tsis sib haum nyob rau hauv cov xovxwm khiav thiab hla lub ntsej muag tuag. Tight clearance tswj tsis yog tsuas yog kom tau tus lej ntawm daim ntawv. Nws yog hais txog kev tsim tus tuag qhov twg txhua qhov kev kam rau ua, los ntawm cov lus qhia rau cov nyees khawm tuag, tiv thaiv tus lej ntawd raws li qhov tiag - ntiaj teb kev tsim khoom.

Clearance thiab kam rau ua txhais li cas huv si txhua txiav cais cov khoom. Tab sis nyob rau hauv ib tug zuj zus tuag, lub sawb yuav tsum tau ua ntej precisely ntawm cov chaw nres tsheb, thiab cov npoo tsim los ntawm kev txiav cov hauj lwm cuam tshuam rau ob leeg sawb tuav thiab tiav ib feem zoo. Cov kev txhawj xeeb no coj ncaj qha mus rau ob qho kev sib txuas tsim qauv: bypass notches thiab burr tswj cov tswv yim.

Bypass Notches thiab Burr Control Strategies

Ib qho kev nce qib tuag strip nce ib lub suab rau ib qho mob stroke, thiab qhov kev ua ntej yuav tsum yog qhov tseeb. Ib feem ntawm ib millimeter deb dhau los lossis luv dhau, thiab cov kws tsav dav hlau tsis tuaj yeem kho qhov yuam kev, qhov av tawm ntawm - qhov chaw, thiab cov ntaub ntawv cuam tshuam. Ob qhov zoo li tus qauv tsim me me, hla tsis dhau kev taw qhia thiab burr orientation, ntsiag to tswj seb lub sawb taug kev ntseeg tau thiab seb cov npoo tiav ua tau raws li qhov yuav tsum tau ua. Kho lawv raws li kev xav tom qab thiab koj yuav siv qhov kev sim tuag caum cov misfeeds thiab ntug kev tsis txaus siab.

Zoo thiab tsis zoo Bypass Notch Functions

Lub bypass notch yog ib tug me me nyem feature txiav rau hauv lub strip layout los tiv thaiv kev cuam tshuam ntawm lub tsiv strip thiab tuag Cheebtsam xws li punches, lifters, tsim nta, los yog trim steels. Lub ntsiab lus ntawm qhov zoo thiab qhov tsis zoo bypass thais nyob rau hauv kev txhim kho tuag tsim txawv ntawm cov khw, tab sis qhov sib txawv ntawm kev ua haujlwm zoo ib yam.

Ib qho zoo bypass notch khaws cia los yog coj cov khoom nyob ib ncig ntawm ib qho kev cuam tshuam thaum khaws cov cab kuj txaus rau kev noj zaub mov ruaj khov. Xav tias nws yog ib qho chaw hauv cheeb tsam uas ua rau txoj hlua khi ruaj ntseg dhau los ntawm thaj chaw tsim lossis thaj chaw tsav tsheb yam tsis muaj kev sib txuas ntawm cov chaw nres tsheb. Qhov tsis zoo bypass notch tshem tawm cov khoom siv tag nrho los tsim kev tshem tawm, muab chav rau cov cuab yeej cuab tam, tsim geometry, lossis kev sib cais. Raws li Hlau Stamping Die Design Insight, lub hom phiaj nyob rau hauv ob qho tib si tsis yog tsuas yog los tsim ib tug thais, tab sis kom sib npaug clearance, carrier zog, strip noj, thiab qhov kawg qhov zoo nyob rau hauv ib tug geometric txiav txim.

Yog tias tsis muaj kev cuam tshuam zoo, ib lub tab tsim los yog flanged ntug tuaj yeem sib tsoo nrog lub punch, lifter, los yog qhov chaw nres tsheb uas nyob ib sab raws li lub sawb nce. Qhov kev sib tsoo ntawd tuaj yeem cuam tshuam cov neeg tuag tam sim ntawd ntawm qhov qis qis lossis, qhov hnyav dua, ua rau muaj kev cuam tshuam tsis zoo ntawm kev tsim khoom nrawm uas nyuaj rau kev kuaj mob. Bypass notches tshem tawm cov kev tsis sib haum xeeb ua ntej thawj qhov kev sim ntaus.

Tsim Notch Geometry rau Feed Accuracy

Bypass notch tsim rau sawb pub raug muaj ntau tshaj li tsuas yog txiav ib lub qhov uas muaj kev cuam tshuam. Qhov ntsuas geometry yuav tsum ua kom tau raws li peb qhov kev sib tw ib txhij:

• Txaus clearance:Lub notch yuav tsum muaj chaw txaus rau cov qauv tsim, xuas nrig ntaus, tsav, lossis strippers ua haujlwm yam tsis tau hu rau lub sawb thaum pub mis.
• Tsim nyog cov cab kuj muaj zog:Kev tshem tawm cov khoom siv ntau dhau ua rau cov neeg nqa khoom tsis muaj zog, ua rau txoj hlua khi, sib tw, lossis buckling thaum lub sij hawm siab - pub mis ceev. Tus neeg nqa khoom tsis muaj zog poob cov khoom noj rov ua dua, thiab cov kws tsav dav hlau ib leeg tuaj yeem cawm tsis tau ib txoj hlua uas tuaj txog ntawm qhov chaw nres tsheb twb deformed.
• Tswj cov khoom sib cais:Notch geometry cuam tshuam li cas cov slugs tso tawm ntawm qhov tuag. Nthuav sab hauv cov ces kaum mloog zoo rau kev ntxhov siab thiab muaj kev pheej hmoo ua kua muag ntxov. Cov kev hloov pauv hloov tau tuav txoj kev ncaj ncees tab sis yuav tsum tau me ntsis tuag vaj tsev.

Thaum lub notch loj dhau lawm, cov cab kuj tseem dhau los ua lub vev xaib nyias uas vibrates thiab flexes ntawm ntau lawm ceev. Thaum nws me dhau lawm, lub sawb rub tawm tsam kev sib sau los yog nqa cov ntsia hlau, rub nws tawm ntawm lub suab. Qhov chaw qab zib nyob ntawm cov khoom thickness, sawb dav, pub ceev, thiab muaj pes tsawg qhov chaw cov cab kuj yuav tsum muaj sia nyob ua ntej txiav.

Cov neeg tsim kev paub dhau los ntsuas qhov kev ua haujlwm tsis yog hauv CAD nkaus xwb, tab sis thaum lub sijhawm sim ntawm kev nce nrawm. Ib qho thais uas zoo nkaus li muaj kev nyab xeeb ntawm 100 strokes ib feeb yuav ua rau kev noj zaub mov tsis ruaj khov ntawm 300. Qhov no yog vim li cas cov neeg koom tes tshwj xeeb nyiamYICENtshuaj xyuas bypass notch tsim raws li ib feem ntawm tag nrho cov strip layout validation, ntsuam xyuas cov cab kuj muaj zog, pilot txoj hauj lwm, thiab pub stability ua ke es tsis kho notches raws li cais nta.

Burr Direction Control thiab Edge Quality Management

Txhua txoj haujlwm shearing ua ib qho burr ntawm ib sab ntawm qhov txiav. Koj tsis tuaj yeem tshem tawm tag nrho, tab sis koj tuaj yeem tswj tau sab twg nws tshwm sim, thiab qhov kev txiav txim siab tseem ceeb rau kev sib dhos, kev nyab xeeb, thiab kev xav kom zoo nkauj.

Nyob rau hauv blanking, cov ntaub ntawv burr nyob rau hauv lub punch sab ntawm qhov dawb paug (sab lub punch nkag). Hauv kev tho, lub burr tshwm rau ntawm qhov tuag ntawm lub sawb (piv txwv li punch nkag). To taub yuav ua li cas tswj burr kev taw qhia nyob rau hauv stamping txhais tau hais tias orienting koj txiav cov hauj lwm kom lub burr ntog rau ib tug uas tsis yog -functional nto: ib tug sab hauv lub ntsej muag muab zais rau hauv lub rooj sib txoos, ib tug nto uas tau txais ib tug thib ob tiav, los yog ib tug ntug uas yuav tsis tiv nrog ib tug neeg teb xov tooj tes.

Compound tuag muaj qhov zoo dua qub ntawm no vim tias txhua tus burrs ntsib ib qho kev taw qhia. Kev tuag tuag yuav tsum tau npaj ntau dua vim tias cov chaw nres tsheb sib txawv tuaj yeem tsim cov burrs ntawm lub ntsej muag sib txawv nyob ntawm seb cov khoom puas raug blanked upward los yog pierced downward. Cov neeg tsim khoom tuag tau hais qhia burr- sab kev taw qhia ntawm daim kab xev layout kos duab, thiab xovxwm cov tswv lag luam xyuas cov kev taw qhia thaum thawj- tshuaj xyuas kab lus.

Ntau yam cuam tshuam rau qhov siab burr hauv kev tuag stamping, thiab lawv cuam tshuam rau txoj hauv kev uas xav tau kev saib xyuas tsis tu ncua:

• Qhov feem pua ​​Clearance:Kev tshem tawm ntau dhau ua rau cov burrs siab dua vim tias cov khoom raug rub thiab torn es tsis yog sheared huv si. Kev tshem tawm tsis txaus tsim cov hlua khi nruab nrab ntau dua li cov burrs classic, tab sis ua kom nrawm nrawm uas nws thiaj li ua rau burrs lawm.
• Punch condition:Ib tug npub punch ntug puag ncig thiab thawb cov khoom ntau dua li shearing nws, ua rau nce burr qhov siab. Ntug degradation yog nce zuj zus, lub ntsiab lus burr qhov siab loj hlob incrementally thoob plaws qhov kev khiav haujlwm.
• Khoom hardness:Cov ntaub ntawv softer tsim cov rollover loj dua thiab ntev burrs ntawm tib clearance vim lawv deform ntau ua ntej fracturing. Cov ntaub ntawv nyuaj tawg sai nrog luv burrs tab sis tsawg dua zam txim rau qhov tsis raug.
• Txiav ceev:Cov xovxwm siab dua ua kom muaj cua sov ntau dua ntawm thaj chaw shear, uas tuaj yeem ua rau cov khoom muag hauv zos thiab ua kom cov burr tsim nyob rau hauv qee cov alloys thaum txo nws hauv lwm tus uas ua rau nkig ntau dua ntawm cov kab mob siab.

Regrinding cov sij hawm khi ncaj qha rau burr qhov siab qhov pib. Feem ntau cov chaw tsim khoom tau teeb tsa qhov siab tshaj plaws uas tau txais burr qhov siab, feem ntau 10% ntawm cov khoom tuab lossis tus nqi tshwj xeeb uas tau teev tseg los ntawm cov ntawv luam tawm. Thaum kev soj ntsuam pom tias burrs mus txog qhov kev txwv ntawd, cov tuag tawm los rau sharpening. Cov neeg tsim qauv cuam tshuam txog kev sib cuam tshuam los ntawm lawv qhov kev xaiv thawj zaug: kev tshem tawm nruj dua feem ntau txhais tau tias kev loj hlob sai dua vim tias cov npoo npoo ua hauj lwm nyuaj dua, thaum qhov kev ua kom zoo tshaj plaws ncua sij hawm ntev tab sis tuaj yeem tso cai me ntsis siab dua thawj burrs. Lub hom phiaj yog txhawm rau nrhiav qhov kev tshem tawm uas tsim cov burrs uas siv tau rau qhov ntev tshaj plaws ntawm cov hlab ntsha ua ntej yuav tsum tau kho.

Bypass thais cov npoo kuj tsim cov burrs, thiab cov burrs tuaj yeem ntes ntawm lifter rails lossis stripper nto thaum pub mis yog tias tsis tswj. Notch txiav punches xav tau tib lub sijhawm tu lub ntsej muag zoo ib yam li ntu - cov khoom xuas nrig ntaus, txawm tias lawv cov kev txiav xaus li seem. Lub burred notch ntug drags tiv thaiv cov khoom tuag, tsub kom noj tsis kam, thiab degrades strip sau npe nyob rau lub sij hawm.
