Yog tsis muaj cov kauj ruam no, tus neeg nqa khoom uas ua haujlwm rau ob lossis peb qhov kev xeem yuav ua tsis tau zoo thaum lub sijhawm ua haujlwm ruaj khov.

Rau cov kev pab cuam tsheb uas tsim tau ntau lab ntawm qhov zoo ib yam, cov txheej txheem tuag stamping ua rau muaj kev sib txuam tsis sib xws ntawm kev ceev, sib xws, thiab kev siv nyiaj txiag. Tab sis cov cuab yeej nws tus kheej tsuas yog kev tsim khoom nkaus xwb-npaj tom qab nws muaj txoj sia nyob mus ib txhis sim thiab siv tau ib ntus, qhov uas cov kev kwv yees ua tau raws li lub cev cov ntawv hlau thiab cov txheej txheem rov ua dua ntawm kev hu xov tooj rau kev ua siab ntev pib.

Yuav ua li cas Electrification thiab Lightweighting Hloov Stamping Tuag rau Hluav Taws Xob Tsheb

Txhua qhov kev vam meej tuag, kev hloov pauv, thiab kab sib txuas tau sib tham txog tam sim no tau tsim nyob rau hauv ib lub sijhawm uas tau tswj hwm los ntawm cov hlau me me ntawm lub cev thiab cov khoom siv hluav taws xob sab hauv. Lub sijhawm ntawd xaus. Hluav taws xob tsheb platforms xav tau kev sib txawv ntawm cov ntawv hlau, cov khoom sib txawv, thiab yog li ntawd, qhov sib txawv tuag engineering. Lub roj teeb pob ib leeg, uas feem ntau sawv cev rau 20 mus rau 25% ntawm EV tag nrho qhov hnyav, qhia txog cov khoom siv uas tsis muaj qhov ua ntej hauv kev tsim tsheb. Rau cov engineers tuag, qhov kev hloov pauv no tsis yog nce ntxiv. Nws rov sau cov cai nyob ib puag ncig tonnage, txheej txheej txheem, thiab cov nyiaj them rov qab.

EV Battery Enclosure thiab Cov Qauv Tuag Yuav Tsum Tau

Daim duab hauv qab ntawm lub tsheb fais fab. Nyob qhov twg ib lub tsheb ib txwm muaj qhov sib kis thiab tso pa tawm, lub EV nqa lub tiaj tus, skateboard-style roj teeb enclosure spanning ze li ntawm tag nrho cov wheelbase. Stamping no enclosure los ntawm cov ntawv hlau tsim ib co ntawm cov loj tshaj plaws thiab deepest kos panels nyob rau hauv automotive ntau lawm.

Cov tais roj teeb xav tau loj- hom tuag muaj peev xwm tsim cov vaj huam sib luag uas tuaj yeem ntev dua 2 meters. Qhov tob ntawm kos yog qhov hnyav vim hais tias lub qhov rooj yuav tsum tau lub tsev roj teeb modules thaum tswj cov txheej txheem rigidity rau kev tiv thaiv kev sib tsoo. Kev xaiv cov khoom sib xyaw ua ke sib tw. Aluminium alloys (5000 thiab 6000 series) yog qhov nrov rau lawv qhov hnyav txuag, tab sis lawv txoj kev nyiam mus rau galling thiab springback ua rau tuag tsim ntau nyuaj tshaj li sib npaug me me steel Cheebtsam.

Steel-raws li kev daws teeb meem tau hloov zuj zus sai thiab. Cleveland-Cliffs thiab AutoForm tau ua qauv qhia txog ib qho -them roj teeb lub tais uas siv lub tshuab txiav-welded blank (TWB) uas sib xyaw ua ke siab heev- lub zog steel rau kev tiv thaiv hauv qab nrog qis dua - lub zog, ntau formable steel nyob rau hauv cov cheeb tsam uas yuav tsum tau deformation hnyav. Lawv qhov kev tsim thawj zaug tau tso AHSS (M1500 lossis M1700 qib) hauv qab lub tiaj tiaj thiab cov hlau me me hauv cov ces kaum thiab cov phab ntsa, tsim kom muaj tus hashtag{10}}zoo li tus qauv uas txo qis weld-kab txav thaum lub sij hawm stamping.Kev simulation thiab kev sim lub cev tau lees paublub resulting tais tau raws li flange flatness yuav tsum tsis muaj ntau tshaj los yog rho tawm 1.5 mm variation, tsis muaj splits los yog wrinkles, tag nrho tsim nyob rau hauv ib tug nias ntaus.

Txoj hauv kev no tshem tawm qhov xav tau ntxiv nyob rau hauv - roj teeb hauv pem teb tiv thaiv thiab txo cov suav suav piv rau ntau -daim txhuas extrusion los ua ke. Tab sis tus tuag nws tus kheej yuav tsum tswj hwm tus cwj pwm txawv ntawm kev sib txawv ntawm ob qib steel hauv ib lub cuab yeej. Kos cov hlaws yuav tsum tau kho nyob rau hauv lub zos, qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

Tshaj li lub roj teeb lub tais, EV- cov qauv tshwj xeeb muaj xws li lub cev muaj zog mounts, pem hauv ntej thiab nram qab subframe reinforcements tsim nyob ib ncig ntawm hluav taws xob tsav tsheb, thiab kev sib tsoo cov qauv tsim los tiv thaiv siab -voltage systems. Txhua tus qhia txog geometries uas cov qauv ICE- era tuag yeej tsis tau ntsib, nrog rau kev ntim khoom txwv uas tau tsav los ntawm lub roj teeb module tso rau hauv es tsis yog lub cav thiab tsav tsheb khiav.

Tsim Tuag rau Advanced High -Strength Steel thiab Aluminium

Kev sib xyaw- cov tswv yim ntawm lub cev yog tam sim no tus qauv thoob plaws EV cov kev pab cuam. Ib lub tsheb ib lub platform yuav siv ultra-siab-lub zog xovxwm- hardened steel rau kev nyab xeeb tawb, dual theem los yog TRIP steels rau cov txheej txheem reinforcements, thiab txhuas rau kaw thiab roj teeb vaj tse. Txhua yam khoom imposes txawv xav tau ntawm daim ntawv hlau stamping tuag uas tsim nws.

Suab complex? Nws yog. AHSS qib nrog lub zog tensile siab tshaj 980 MPa tuaj yeem ncav cuag qhov tseem ceeb hardnessplaub mus rau tsib zaug siab dua cov hlau me me, nrog qee qib martensitic tshaj 57 HRC. Nyob rau theem ntawd, cov ntawv hlau mus txog qhov nyuaj ntawm qhov tuag nws tus kheej. Cov tswv yim cuab yeej txheem txheej txheem poob rau hauv cov xwm txheej no. D2 cuab yeej hlau uas kav ntev li 50,000 lub voj voog ntawm cov hlau me me tuaj yeem ua tsis tau zoo tom qab 5,000 txog 7,000 lub voj voog ntawm 580 MPa ferrite - qib bainite, cia nyob ib leeg 1180 MPa dual theem steel.

Siab dua - cov ntaub ntawv muaj zog kuj xav tau cov xovxwm ntau dua, qee zaum ob mus rau plaub npaug ntawm cov hlau me me xav tau rau qhov sib npaug ntawm cov duab kos duab. Qhov kev quab yuam no nce ntxiv los ntawm tag nrho cov txheej txheem tuag: hnyav dua cov khau, cov lus qhia nruj dua, cov xovxwm txhawb nqa, thiab hloov kho cov hlaws dai tsim uas tswj cov khoom ntws tsis tau tawg ntawm daim ntawv. Qhov txo qis ua kom pom los ntawm AHSS paradoxically ua rau muaj kev sib tw ua kom tawv nqaij, yuav tsum tau muaj zog dua blankholder uas ntxiv nrawm hnav ntawm kos radii thiab binder nto.

Aluminium stamping tuag tsim nthuav tawm hom kev ua tsis tiav tag nrho. Tsis yog kev hnav los ntawm cov ntawv tawv tawv, aluminium adheres rau cov cuab yeej los ntawm micro- vuam ntawm kev sib txhuam- cov ntsiab lus sib cuag. Cov txheej txheem galling no txhim kho kev nce qib, nrog rau cov khoom xaum txhuas tau qhab nia tom qab panels thiab degrading nto zoo. Cov chaw tuag yuav tsum tau polished rau qhov tsis tshua muaj roughness qhov tseem ceeb (hauv qab Ra 0.2 micrometers) thiab tiv thaiv nrog qis- cov coatings kev sib txhuam ua kom zoo rau txhuas tus cwj pwm nplaum.

Cov lus hauv qab no sib piv yuav ua li cas cov ntaub ntawv no hloov pauv mus rau hauv qhov sib txawv ntawm qhov sib txawv engineering:

Pom qhov sib txawv hauv cov tswv yim. AHSS xav tau brute- quab yuam los ntawm qhov tuag substrate, nrog cov coatings ua haujlwm feem ntau yog hnav thaiv tiv thaiv cov ntaub ntawv uas yuav luag zoo li lub cuab yeej. Aluminium xav tau kev nplua nuj, nrog daim iav- polished nto thiab kev sib txhuam- txo cov txheej txheem uas tiv thaiv cov ntawv softer los ntawm kev sib txuas rau lub ntsej muag tuag. Ib lub cev EV ib leeg-hauv- qhov kev pabcuam dawb yuav xav tau ob lub tswv yim uas siv los ntawm cov khoom sib txawv, qee zaum nyob rau hauv ntau qhov chaw ntawm tib qhov kev hloov pauv tuag.

Kev simulation ua lub luag haujlwm tseem ceeb hauv aluminium stamping tuag tsim thiab AHSS tuag engineering tib yam. Qhov hnyav springback pom nyob rau hauv siab - lub zog steel roj teeb tais, qhov twg thawj TWB tsim tsim twisting uas ua txhaum lub 1.5 hli flatness yuav tsum tau rau leak-tight flanges, tau txheeb xyuas thiab daws los ntawm iterative AutoForm simulation ua ntej lub cev prototyping paub tseeb tias qhov kho. Kev sim virtual tsis yog xaiv tau rau cov ntaub ntawv no lawm. Nws yog tib txoj hauv kev uas muaj txiaj ntsig zoo rau kev sib koom ua ke ntawm kev tsim qauv ua haujlwm thaum lub cev rov ua haujlwm ntawm 2-meter- ntev cov cuab yeej sib sib zog nqus kos nqi ntau lub lis piam thiab ntau pua txhiab nyiaj rau ib lub voj voog.

Cov khoom siv thiab cov duab geometry no tsis xaus ntawm kev tsim tuag. Lawv nqa ncaj qha mus rau hauv kev sim, qhov uas simulation twv ua tau raws li cov ntawv hlau tus cwj pwm tiag tiag, thiab cov txheej txheem rov ua dua ntawm qhov tseeb ntawm qhov tseeb, qhov zoo ntawm qhov chaw, thiab cov qauv kev ua haujlwm txiav txim siab seb qhov tuag puas yog tiag tiag-npaj.

Tuag sim thiab validation ua ntej pawg ntau lawm

Lub cuab yeej stamping thiab tuag tuaj yeem saib tsis muaj qhov tsis zoo ntawm lub khw hauv pem teb thiab tseem tsim cov panels riddled nrog splits, wrinkles, los yog dimensional deviations uas tsis muaj kev sib dhos cog yuav txais. Qhov sib txawv ntawm lub tshuab tshiab tshiab thiab kev tsim khoom- cov cuab yeej pom zoo yog txuas nrog los ntawm kev sim, kev ua kom zoo, rov ua kom raug raws li qhov feem ntau siv 30% ntawm tag nrho cov cuab yeej siv thiab kwv yees li 40% ntawm tag nrho cov txheej txheem engineering. Hla lossis maj nrawm rau theem no, thiab cov teeb meem tsis zoo tsiv mus rau hauv qab mus rau lub cev-hauv- lub rooj sib txoos dawb uas lawv ua tau kim dua los kho.

Yog li dab tsi tshwm sim ntawm lub sijhawm tuag tawm ntawm lub chaw machining thiab hnub nws khiav ntawm qhov nrawm nrawm? Cov txheej txheem stamping tuag sim ua raws li cov txheej txheem ntawm kev kuaj lub cev, ntsuas lub voj voog, thiab rov kho dua, txhua tus tswj hwm los ntawm OEM- cov qauv kev lees paub tshwj xeeb.

Tuag Tryout theem los ntawm Spotting rau OEM pom zoo

Txhua lub tsheb stamping tuag dhau los ntawm tib lub hauv paus validation theem, txawm tias qhov tob thiab nruj ntawm txhua theem ntsuas nrog ib feem tseem ceeb. Chav Kawm A sab nrauv vaj huam sib luag tuag yuav siv lub hlis hauv kev sim. Ib qho yooj yim bracket tuag yuav ntshiab nyob rau hauv hnub. Nov yog qhov kev ua haujlwm ua ntu zus:

• Springback sib txawv:Elastic rov qab tom qab cov xovxwm qhib tsav lub vaj huam sib luag tawm ntawm kev ua siab ntev. Kev kho yuav tsum muaj re-machining tuag saum npoo kom dhau-pab, qee zaum yuav tsum tau ua ntau zaus raws li txhua qhov kev hloov pauv hloov cov qauv springback rau lwm qhov ntawm lub vaj huam sib luag.
• Qhov defects:Qhov tsis zoo tsuas yog pom nyob rau hauv kev tswj teeb pom kev zoo, suav nrog cov cim dab dej ntawm cov hlua khi, cov cim tuag los ntawm qhov pom tsis tiav, lossis cov cim zawv zawg los ntawm cov khoom siv tsis raug. Kev daws cov no ntawm Class A tuag xav tau kev sib tsoo hauv zos thiab rov- polishing.

Txhua qhov kev kho kom raug ua raws tib lub voj voog: hloov kho qhov tuag, stamp tshiab panels, ntsuas, sib piv. Nws yog kev mob siab rau kev ua haujlwm, tab sis nws yog dab tsi cais cov cuab yeej uas siv tau cov khoom siv los ntawm ib qho uas tuav Class A kam rau ntawm 12 strokes ib feeb, ua haujlwm tom qab ua haujlwm, rau tsib xyoos lossis ntau dua ntawm kev tsim khoom.

Tuag validation paub meej tias cov cuab yeej tuaj yeem ua qhov zoo. Ua kom nws ua qhov zoo tshaj li ntau lab lub voj voog qhia txog kev qhuab qhia sib txawv: kev npaj kho, kev saib xyuas, thiab kev tswj xyuas tsis ua haujlwm uas tiv thaiv cov teeb meem me me los ntawm txoj kab uas tsis tau npaj tseg.

Stamping Tuag Failure Hom thiab Kev Kho Teeb Meem

Kev lees paub lees paub tias tuag tuaj yeem tsim cov khoom zoo. Ua kom nws tsim cov khoom zoo thoob plaws ntau lab lub voj voog yog qhov sib txawv kiag li. Nyob rau hauv siab - kev kub ceev tsheb stamping, ib teev ntawm lub sijhawm tsis tau npaj tseg tuaj yeem raug nqi $ 26,000 txog $ 260,000 lossis ntau dua nyob ntawm cov nroj tsuag. Txawm li cas los xij feem ntau stamping tuag tsis ua haujlwm hom thiab kho qhov xwm txheej tau kwv yees tau, uas txhais tau tias lawv tuaj yeem tiv thaiv tau. Qhov sib txawv ntawm reactive firefighting thiab proactive tswj los mus nkag siab txog yuav ua li cas tuag degrade thiab tsim ib tug stamping tuag tu lub sij hawm uas catches hnav ua ntej nws yuav seem.

Common Die Failure Modes hauv Automotive Stamping

Txhua tus tuag qhia ib zaj dab neeg los ntawm nws cov qauv hnav. Thaum koj paub tias yuav nrhiav dab tsi, cov pov thawj lub cev taw qhia ncaj qha rau hauv paus ua rau. Ntawm no yog cov hom kev ua tsis tiav uas pawg ntau lawm ntsib feem ntau ntawm cov tsheb stamping kab:

Txiav ntug hnav thiab tawg.Qhov no yog hom tsis ua haujlwm tshaj plaws. Kev sib txhuam ntawm cov ntawv hlau thiab qhov chaw txiav maj mam sib npaug ntawm ntug profile, ua kom loj dua burrs ntawm qhov chaw stamped. Nrog rau qib AHSS, tus nqi hnav abrasive nrawm nrawm heev vim tias cov ntaub ntawv hardness mus txog ntawm cov cuab yeej nws tus kheej. Carbide stamping tuag ntawm qhov chaw tho qhov tiv thaiv qhov degradation ntev dua li cov cuab yeej siv hlau, tab sis txawm tias carbide inserts nws thiaj li yuav tsum tau regrinding lossis hloov.

Kos lub voj voog tawg.Kev tsim cov radii muaj kev sib tiv tauj siab raws li cov ntawv hlau ntws hla lawv thaum txhua qhov mob stroke. Thaum lub sij hawm, micro- polishing hloov mus rau galling, tom qab ntawd mus rau saum npoo roughening uas cim txhua lub vaj huam sib luag hla. Ntawm chav kawm A tuag, txawm tias lub vojvoog hloov maj mam dhau los ua pom ntawm lub vaj huam sib luag stamped nto.

Cracking los ntawm thermal qaug zog thiab mechanical overload.Cyclic loading qhia txog micro- tawg ntawm cov ntsiab lus kev ntxhov siab xws li cov ces kaum sab hauv, kev hloov ntawm cov fillet, thiab cov chaw uas muaj qhov tsis xws luag. Cov kab nrib pleb no loj hlob zuj zus ntxiv nrog txhua qhov xovxwm. Thermal fatigue compounds qhov teeb meem, tshwj xeeb tshaj yog nyob rau hauv siab -kev khiav hauj lwm ceev qhov kev sib txhuam-tsim tshav kub cycles tsim expansion thiab contraction stresses ntawm tuag nto. Yog tias tsis kuaj pom, micro- tawg tawm mus txog thaum muaj kev puas tsuaj loj tshwm sim.

Galling.Tshwj xeeb yog muaj teeb meem nrog txhuas thiab siab heev - steels muaj zog, galling tshwm sim thaum cov ntaub ntawv hloov los ntawm daim ntawv mus rau qhov tuag nto los ntawm micro- vuam ntawm kev sib txhuam- cov ntsiab lus rhuab. Nrog aluminium, cov khoom hloov pauv tau nce zuj zus, suav nrog cov vaj huam sib luag tom ntej. Nrog AHSS, qhov kev sib cuag huab cua tuaj yeem rub tawm PVD txheej thiab pib ua cov nplaum rau ntawm qhov chaw raug. Galling yog tshwj xeeb yog insidious vim hais tias nws accelerates ib zaug pib, txhua lub voj voog nias cov khoom xa mus tob rau hauv qhov tuag.

Lub sijhawm thiab pub- cuam tshuam txog kev ua tsis tiav.Progressive dies nyob ntawm qhov tseeb synchronization ntawm cov xovxwm stroke, strip feed advance, thiab pilot pin engagement. Thaum pub pitch drifts, pilot lub sij hawm hloov, los yog strip lifters khi, lub strip tuaj txog ntawm chaw nres tsheb me ntsis tawm - txoj hauj lwm. Qhov tshwm sim yog los ntawm qhov tsis raug thiab qhov txawv txav mus rau kev puas tsuaj slug rub qhov twg cov slugs raug rub rov qab rau hauv lub ntsej muag tuag, ua rau cov npoo txiav thiab tsim cov chaw hauv ib leeg.

Cov lus hauv qab no qhia txog cov kev ua tsis tiav no rau lawv cov hauv paus hauv paus, cov tsos mob pom ntawm cov khoom siv hauv pem teb, thiab cov kev kho uas daws lawv:

Kev Tiv Thaiv Kev Tiv Thaiv Cov Sijhawm Saib Xyuas Kev Tiv Thaiv thiab Kev Tshuaj Xyuas Cov Cai

Reactive txij nkawm raug nqi peb mus rau tsib zaug ntau dua li qhov kev pab cuam npaj.
