Dab tsi yog Progressive Tuag Steel Stamping

Xav txog ib qho cuab yeej uas xuas nrig ntaus, khoov, daim ntawv, thiab txiav ib txoj hlua hlau rau hauv ib qho ua tiav - tag nrho yam tsis muaj nres. Qhov ntawd yog lub tswv yim tseem ceeb tom qab kev nce qib tuag steel stamping, thiab nws yog ib txoj hauv kev ua tau zoo tshaj plaws uas tau tsim los tsim cov khoom siab tshaj - ntim cov hlau nrog kev ua siab ntev thiab kev ua haujlwm tsawg.

Txawm hais tias koj yog tus kws tsim khoom tsim kho lub sijhawm ua haujlwm zoo lossis tus kws tshaj lij kev muag khoom soj ntsuam ib qho -daim kev lag luam, kev nkag siab txog cov txheej txheem no ua haujlwm li cas - thiab nws txawv li cas los ntawm lwm txoj hauv kev - yog qhov tseem ceeb rau kev tsim cov cuab yeej zoo. Cov lus qhia no rhuav tshem cov tshuab, kev xav txog cov khoom siv, cov qauv nqi, thiab cov tswv yim kev saib xyuas uas txiav txim siab seb puas muaj cov hlau stamping yog qhov haum rau koj cov khoom steel.

Defining Progressive Tuag Steel Stamping

Yog lidab tsi yog ib tug progressive tuag, raws nraim? Ntawm nws qhov yooj yim tshaj plaws, nws yog ib qho cuab yeej uas muaj ntau qhov chaw nres tsheb nyob rau hauv ib ntus, mounted hauv lub xovxwm stamping. Lub kauj -piv steel sawb nce mus txog qhov tuag ib qho kev nce ntxiv (hu ua lub suab) nrog rau txhua qhov kev mob stroke. Txhua qhov chaw nres tsheb ua haujlwm sib txawv - tho, khoov, sib sau, lossis txiav - ib txhij ntawm ntau ntu ntawm cov sawb. Ib feem ua tiav poob tawm ntawm qhov chaw nres tsheb zaum kawg nrog txhua qhov stroke ntawm xovxwm.

Progressive tuag steel stamping yog qhov siab - ntim cov hlau tsim cov txheej txheem uas cov hlau txuas txuas ntxiv mus dhau los ntawm ntau- chaw nres tsheb tuag, nrog rau txhua qhov chaw nres tsheb ua haujlwm ua ntu zus - tho, sib sau, khoov, lossis txiav - kom txog rau thaum ib feem ua tiav yog sib cais los ntawm cov kab nrib pleb nrog txhua qhov xovxwm stroke.

Lo lus "kev vam meej" piav qhia meej txog qhov tshwm sim: cov hlau nce mus txog qhov tuag, chaw nres tsheb los ntawm chaw nres tsheb, txhua kauj ruam lub tsev ntawm qhov kawg. Lub sawb tseem txuas nrog lub web carrier web (scrap skeleton) thoob plaws tag nrho cov kab ke, uas tswj txoj haujlwm tswj thiab tshem tawm qhov xav tau ntawm kev sib cais ntawm kev ua haujlwm. Qhov xwm txheej tas mus li no yog qhov ua rau muaj kev vam meej stamping nws cov txiaj ntsig ceev - xovxwm tuaj yeem khiav ntawm 25 mus rau ntau dua 300 strokes ib feeb, tsim ntau txhiab qhov zoo tib yam steel ib teev.

Yuav ua li cas nws txawv ntawm Hloov thiab Compound Die Methods

Progressive tuag stamping tsis yog tib txoj hauv kev kom tuag thiab stamping rau steel qhov chaw. Hloov tuag stamping thiab compound tuag stamping txhua qhov ua haujlwm sib txawv, thiab xaiv txoj kev tsis ncaj ncees tuaj yeem txhais tau tias kev siv nyiaj ntau dhau ntawm kev siv lossis kev txi ntau dhau.

Hauv kev hloov pauv tuag stamping, lub workpiece raug cais tawm ntawm lub sawb thaum ntxov. Mechanical fingers los yog grippers ces txav tus neeg dawb paug ntawm cov chaw nres tsheb ywj pheej. Qhov no ua rau kev hloov pauv tuag tau zoo- haum rau qhov loj dua uas lub cev tsis tuaj yeem txuas nrog ib txoj hlua khi thaum lawv taug kev los ntawm ntau theem. Kev lag luam-tawm yog qeeb qeeb qeeb thiab qhov nyuaj dua - tuav cov txheej txheem.

Compound tuag stamping siv txoj hauv kev rov qab: nws ua ntau yam haujlwm txiav - zoo li blanking thiab tho - hauv ib zaug nias stroke ntawm ib qho chaw nres tsheb. Nws muaj txiaj ntsig zoo rau qhov chaw tiaj tus uas xav tau kev ua haujlwm siab hauv ib lub dav hlau, tab sis nws tsis tuaj yeem ua ntau yam - kauj ruam ua ntu xws li khoov, kos, lossis embossments.

Progressive tuag dhau los ua qhov kev xaiv zoo tshaj plaws thaum koj xav tau cov duab geometry nyuaj, ntim siab, thiab lub sijhawm nrawm nrawm hauv tib pob. Lawv ua ke ntau - muaj peev xwm ua haujlwm ntawm kev hloov pauv tuag nrog kev ceev ntawm ib qho - chaw nres tsheb txoj kev - tag nrho yam tsis muaj kev sib cais ntawm cov chaw nres tsheb.

Rau cov kws tsim khoom tsim ua haujlwm steel qhov chaw ntawm qhov ntsuas, kev tuag stamping tsis tu ncua muab tus nqi qis tshaj rau ib -cov nqi thaum ib feem geometry suav nrog ntau yam haujlwm thiab cov khoom txhua xyoo ua pov thawj rau cov cuab yeej peev. Cov lus nug tiag tiag tsis yog tias cov txheej txheem ua haujlwm li cas - nws yog qhov kev xaiv cov khoom siv, kev tsim qauv tuag, thiab kev saib xyuas zoo li cas nws lub sijhawm ntev - kev lag luam.

Yuav Ua Li Cas Progressive Die Stamping Txheej Txheem Ua Haujlwm

Qhov kom zoo dua ntawm kev nce qib stamping tuag yog los ntawm ib txoj hauv kev zoo nkauj: txhua qhov xovxwm stroke ua haujlwm tau zoo ntawm txhua qhov chaw nres tsheb ib txhij. Thaum ib ntu ntawm lub sawb tau txais nws qhov pierced, lwm qhov yog khoov, thiab lwm qhov tau txais nws qhov kawg txiav tawm - tag nrho hauv tib lub sijhawm. Nkag siab txog cov txheej txheem tuag no txij thaum pib mus txog rau thaum xaus qhia tias vim li cas qhov kev hloov pauv nyob qis qis thiab yog vim li cas steel tus cwj pwm kev siv tshuab tseem ceeb ntawm txhua theem.

Sawb pub thiab khoom ua ntej

Covtxheej txheem tuag stampingpib ntawm lub uncoiler, qhov twg steel kauj - feem ntau hnyav pua pua lossis txhiab phaus - yog mounted thiab unwound. Lub strips dhau los ntawm ib tug straightener uas tshem cov coil teeb (lub curvature khaws cia los ntawm qhov txhab ntawm ib tug spool). Rau cov hlau, cov kauj ruam no yog qhov tseem ceeb vim tias qhov seem curvature ua rau cov khoom noj tsis sib xws thiab kev sib cuag nrog cov chaw tuag.

Los ntawm lub straightener, ib tug servo feeder nce lub sawb ib tug meej nyob deb - lub feed pitch - nrog rau txhua lub zog stroke. Lub suab no phim qhov chaw nres tsheb sib nrug hauv qhov tuag, yog li txhua qhov chaw nres tsheb tau txais cov seem ntawm txoj hlua ntawm lub sijhawm raug. Pub raug rau cov tshuab niaj hnub no feem ntau tuav hauv ob peb txhiab ntawm ib nti.

Thaum lub sawb nkag mus rau hauv qhov tuag, tus tsav pins coj los tswj qhov chaw. Cov pins tawv tawv no poob rau hauv ua ntej- tho qhov hauv lub sawb ua ntej cov xovxwm kaw, kho qee qhov yuam kev me me feeder thiab xauv lub sawb mus rau qhov sib npaug. Yog tsis muaj kev txhim khu kev qha piloting, qhov me me yuam kev sib sau los ntawm chaw nres tsheb. Rau steel strips, pilot qhov clearances yog feem ntau tuav rau 0.0005 mus rau 0.001 ntiv tes kom tuav nruj sau npe nyob rau hauv tag nrho tuag ntev.

Sequential chaw nres tsheb ua haujlwm nyob rau hauv ib leeg Xovxwm Stroke

Ntawm no yog qhov uas cov txheej txheem stamping zuj zus muab nws cov khoom tsim tau. Thaum cov xovxwm ram nqis los, txhua qhov chaw nres tsheb hauv qhov tuag ua nws txoj haujlwm ua haujlwm tib lub sijhawm - ntawm ntau ntu ntawm tib lub strip. Chaw nres tsheb ib tug yuav tho qhov pilot qhov, chaw nres tsheb ob tsim qhov chaw ua hauj lwm, chaw nres tsheb peb khoov ib tab, chaw nres tsheb plaub daim ntawv ib tug tav, thiab chaw nres tsheb tsib executes qhov kawg txiav.

Ib feem tsis yog "ua tiav" kom txog thaum nws dhau los ntawm txhua qhov chaw nres tsheb. Nyob rau hauv txoj kev, nws tseem txuas nrog cov cab kuj strip (cov pob txha pob txha), uas ua raws li ob qho tib si kev thauj mus los thiab kev sau npe siv. Tsuas yog ntawm qhov chaw nres tsheb kawg nkaus xwb cov khoom tiav cais tawm ntawm lub sawb thiab tau ejected los yog sau hauv qab qhov tuag.

Qhov no ib txhij multi- chaw nres tsheb qhov kev txiav txim txhais tau hais tias ib tug zuj zus tuag xovxwm tsim ib tug tiav ib feem ntawm stroke - tsis hais seb yuav tsum tau ua ntau npaum li cas cov hauj lwm los tsim nws. 12-chaw nres tsheb tuag khiav ntawm 150 strokes ib feeb tseem outputs 150 qhov chaw ib feeb, tsis yog 150 faib los ntawm 12.

Xovxwm Mechanics thiab Cycle Integration

Yog li cas lub stamping xovxwm ua hauj lwm nyob rau hauv kev sib koom tes nrog ib tug zuj zus tuag? Cov xovxwm xa cov tonnage tswj los ntawm ib tug neeg kho tshuab los yog servo-tsav ram, cycling lub Upper tuag ib nrab mus rau lub qis ib nrab nrog meej stroke ntev thiab ceev. Tonnage yuav tsum tshaj qhov sib xyaw ua ke thiab tsim cov rog thoob plaws txhua qhov chaw ib txhij - qhov tseem ceeb ntawm kev txiav txim siab thaum stamping steel.

Steel tus yam ntxwv springback ntxiv lwm txheej ntawm complexity. Tom qab txhua txoj haujlwm tsim, cov khoom xav tau ib nrab rov qab los ntawm nws cov qauv qub vim elastic strain. Siab dua - lub zog steels caij nplooj ntoos hlav rov qab ntau dua, xav tau cov xovxwm loj tshaj plaws kom xa cov hauv qab zoo ib yam -tuag- qhov chaw nyob nruab nrab thiab, qee zaum, nyob rau hauv qab ntawm cov hlab ntsha kom tso cai rau cov nyiaj npib lossis calibration chaw nres tsheb kom tag nrho cov tsim geometry.

Stroke ceev, kaw qhov siab, thiab lub sij hawm pub mis yuav tsum synchronize zoo kawg nkaus. Lub feeder tso tawm cov sawb tsuas yog thaum lub qhov tuag qhib, cov neeg tsav dav hlau koom ua ntej kev txiav lossis kev pib pib, thiab cov xovxwm thim rov qab ua ntej cov lifters tsa lub sawb rau kev ua ntej tom ntej. Txhua lub sij hawm tsis sib haum xeeb ua rau cov hlua tsis zoo, cov tsav tsheb puas, lossis cov khoom seem.

Ntawm no yog tag nrho cov txheej txheem tuag stamping nyob rau hauv ib ntus:

1. Coil loading - steel kauj mounted ntawm lub uncoiler
2. Straightening - strip flattened kom tshem tawm coil teeb
3. Lubrication - siv los txo kev sib txhuam thiab cov cuab yeej hnav
4. Servo pub mis - strip tau nce siab los ntawm ib lub suab ib zaug
5. Pilot pin kev koom tes - strip xauv rau hauv txoj hauj lwm meej
6. Chaw nres tsheb ua haujlwm - txiav, tho, sib sau, khoov ua ib txhij ntawm txhua qhov chaw nres tsheb
7. Sawb lifting - lifters tsa lub sawb kom tshem tawm cov ntsiab lus qis dua
8. Pub ua ntej - strip txav mus rau ib lub suab rau lub voj voog tom ntej
9. Kev txiav tawm zaum kawg - tiav ib feem cais tawm ntawm cov cab kuj
10. Part ejection and collection - ua tiav cov khoom tawm ntawm qhov tuag

Txhua lub voj voog rov ua dua hauv feem ntawm ib thib ob. Qhov tsis tu ncua, tsis muaj kev cuam tshuam ntawm cov txheej txheem no - tsis muaj kev tuav, tsis muaj kev hloov pauv, tsis muaj kev cuam tshuam ntawm tus neeg teb xov tooj ntawm kev ua haujlwm - yog qhov ua rau muaj kev vam meej tuag steel stamping lub neej ntawd xaiv rau siab - ntim ntau lawm qhov twg steel qhov chaw xav tau ntau yam txheej txheem thiab kev tswj kom nruj.

Tau kawg, tsis yog txhua qib steel coj zoo ib yam hauv kev tuag zuj zus. Sawb noj kev ntseeg siab, tsim cov kev txwv ntawm txhua qhov chaw nres tsheb, thiab nias tonnage xav tau tag nrho cov kev hloov pauv loj nyob ntawm seb koj puas siv cov pa roj carbon me me los yog siab -lub zog stainless - thiab cov khoom sib txawv ntawm cov khoom tsim kev txiav txim siab.

Steel Qib thiab cov khoom xaiv rau Progressive Dies

Cov qib steel koj pub rau hauv kev tuag zuj zus tsis yog cuam tshuam rau qhov kawg ntawm qhov kev ua tau zoo - nws dictates ze li txhua qhov txheej txheem, los ntawm xovxwm tonnage thiab punch clearance rau chaw nres tsheb suav thiab pub kev ntseeg tau. Ob qhov chaw nrog geometry zoo tib yam tab sis cov qib steel sib txawv tuaj yeem xav tau cov qauv tsim qauv sib txawv. Tias yog vim li cas kev xaiv cov khoom siv stamping yog ib qho ntawm qhov ntxov tshaj plaws thiab feem ntau qhov kev txiav txim siab engineering hauv ib qhov project.

Common Steel Qib rau Progressive Stamping

Cov hlau twg ua haujlwm tau zoo nyob rau hauv ntau- chaw nres tsheb nce qib tuag? Cov lus teb nyob ntawm ib feem muaj nuj nqi, xav tau formability, thiab ntau lawm ntim. Ntawm no yog cov feem ntau teev teev rau steel progressive stamping:

• Tsawg- carbon steel (1008, 1010, 1018)- Lub workhorse ntawm carbon steel zuj zus stamping. Cov qhab nia no muaj qhov zoo tshaj plaws ductility, tsis muaj zog tawm los, thiab kev kwv yees ua tus cwj pwm. Lawv zoo tagnrho rau cov brackets, clips, chassis Cheebtsam, thiab cov khoom siv dav dav uas xav tau kev khoov thiab rub tawm yam tsis muaj kev pheej hmoo tawg.
• 300-series stainless hlau (304, 316)- Xaiv rau kev tiv thaiv corrosion hauv kev kho mob, kev pabcuam zaub mov, thiab kev siv dej hiav txwv. Stainless hlau nce qib stamping nthuav qhia kev ua haujlwm siab dua- hardening tus nqi, uas txhais tau hais tias txhua qhov chaw tsim khoom ntxiv cov kev ntxhov siab ntau ntxiv rau cov sawb. Qhov no xav kom ceev faj chaw nres tsheb sib txuas thiab feem ntau qhov chaw nres tsheb dav dua.
• High-lub zog qis- alloy (HSLA) steel- Cov qhab nia zoo li HSLA 340, 420, thiab 550 muab cov khoom muaj zog muaj zog nrog cov qauv tsim. Lawv muaj nyob rau hauv automotive structural applications qhov twg qhov hnyav txo qhov teeb meem. HSLA steels xav tau cov xovxwm ntau dua thiab cov nyiaj them rov qab nruj dua li cov hlau me me.
• Caij nplooj ntoos hlav steel (1074, 1095, 301 stainless)- Siv rau qhov chaw uas yuav tsum yoog ntau zaus yam tsis muaj deformation mus tas li. Cov qib siab - carbon lossis tempered qib no muaj qhov txwv tsis pub siv, txwv qhov hnyav ntawm kev ua haujlwm ntawm txhua qhov chaw nres tsheb. Cov neeg tsim khoom tuag feem ntau ntxiv cov chaw nres tsheb ntau nrog kev sib sau ua ntu zus kom tsis txhob tawg.

Kev qhia cov khoom siv yooj yim "1008 steel" tseem tawm hauv chav rau kev hloov pauv ntawm cov cuab yeej tseem ceeb. Raws liMetalForming Magazinesau ntawv, lub tshuab nqus tsev-degassed qis- carbon steel, kos duab- zoo steel, thiab kev lag luam- cov hlau zoo tuaj yeem poob rau tib qhov kev qhia tshwj xeeb tseem ua tau txawv ntawm qhov tuag. Cov tuag qhov yuav tsum tau - tsis yog lub chaw yuav khoom qhov nyiam rau qhov kev xaiv pheej yig tshaj - yuav tsum txiav txim siab qhov kawg hu rau cov khoom.

Yuav ua li cas Steel Properties Influence Tuag Tsim thiab Xovxwm Requirements

Txhua qib steel nqa ib tus ntiv tes tshwj xeeb ntawm cov khoom siv kho tshuab, thiab cov khoom no txhais ncaj qha rau hauv cov hlau stamping tuag kev txiav txim siab. Koj yuav pom cov teebmeem hauv plaub qhov tseem ceeb:

Tensile zog thiab nias tonnage.Lub zog tensile siab dua txhais tau tias ntau lub zog xav tau rau txhua qhov kev txiav thiab kev ua haujlwm. Ib tug 304 stainless sawb nrog 75 ksi tensile lub zog xav tau roughly 50% ntau blanking quab yuam tshaj 1010 me me hlau ntawm 50 ksi, piv txwv li tib thickness thiab perimeter. Ua kom ntau dhau ntawm txhua qhov chaw nres tsheb, thiab nias lub zog tonnage nce nrawm. Undersizing cov xovxwm tsis yog cia li nres ntau lawm - nws ua rau cov cuab yeej puas thiab qhia qhov dav dav.

Ductility thiab qhov tsawg kawg nkaus khoov vojvoog.Cov ntaub ntawv feem pua ​​​​elongation txiav txim siab npaum li cas nws tuaj yeem khoov tau yam tsis muaj kev tawg ntawm cov chaw tsim khoom. Tsawg- carbon steels nrog 35-45% elongation kam rau sab hauv khoov radii kom nruj li 0.5 npaug ntawm cov khoom tuab. HSLA steels ntawm 15-20% elongation yuav xav tau 2x thickness los yog ntau dua. Qhov no cuam tshuam ncaj qha rau ntau npaum li cas kev tsim tuaj yeem tshwm sim ntawm ib qho chaw nres tsheb thiab pes tsawg qhov chaw tuag xav tau tag nrho.

Ua haujlwm- tus nqi hardening thiab ntau- chaw nres tsheb cuam tshuam.Txhua qhov kev ua haujlwm txias- ua haujlwm cov hlau, ua kom nws cov tawv tawv thiab txo nws cov ductility seem. Cov ntaub ntawv uas muaj kev ua haujlwm siab- cov nqi hardening - zoo li austenitic stainless hlau - poob formability sai dua thaum lawv nce los ntawm cov chaw nres tsheb. Cov neeg tsim khoom tuag them nyiaj los ntawm kev ntxiv cov chaw nres tsheb rau kev ntxhov siab rov ua dua lossis los ntawm kev txwv qhov hnyav ntawm txhua kauj ruam tsim. Tsis quav ntsej txog kev ua haujlwm- kev coj tus cwj pwm hnyav yuav ua rau muaj kev puas tsuaj tom qab cov chaw nres tsheb uas cov sawb tau tag lawm nws cov formability.

Yield zog thiab springback.Tom qab txhua qhov khoov lossis daim ntawv, cov hlau ib nrab rov qab mus rau nws cov duab qub. Lub zog tawm los ntau dua ua rau muaj kev txhoj puab heev springback, uas txhais tau hais tias tsim cov chaw nres tsheb yuav tsum overbend dhau lub hom phiaj lub kaum sab xis. Nyob rau hauv ib tug zuj zus tuag, springback nyiaj them yuav tsum tau calibrated chaw nres tsheb los ntawm qhov chaw nres tsheb, vim hais tias lub strip lub yield zog nce vim ua hauj lwm hardening raws li nws nce mus los ntawm lub cuab tam.

Thickness ranges thiab lawv cov txheej txheem cuam tshuam

Progressive tuag kov steel thicknesses los ntawm kwv yees li 0.1 hli (0.004 ") mus txog ib ncig ntawm 6 hli (0.250"), tab sis feem ntau ntau yam rau precision Cheebtsam poob ntawm 0.2 hli thiab 3 hli. Dhau lub qhov rais no, cov txheej txheem yuav ua tsis tau zoo ntxiv - cov ntaub ntawv tuab heev tiv thaiv flattening thiab strain feeder mechanisms, thaum ultra-thin foils buckle nyob rau hauv strip nro thiab yog ib qho nyuaj rau pilot reliably.

Thickness cuam tshuam rau kev txhim kho tuag tsim nyob rau hauv ntau txoj kev sib txuas:

• Chaw nres tsheb layout ceev- Cov ntaub ntawv tuab dua yuav tsum muaj cov punch loj dua -kom- tuag clearances, uas txhais tau tias cov seem tuag loj dua ntawm txhua qhov chaw nres tsheb. Qhov no ncab qhov ntev tag nrho tuag thiab txo cov chaw nres tsheb ntau npaum li cas tuaj yeem haum rau hauv ib lub txaj xovxwm.
• Pilot pin sizing- Pilot qhov yuav tsum tswj kom txaus ntug nyob deb txheeb ze rau strip thickness. Thicker strips xav tau tus tsav tus pins loj dua thiab yog li ntawd qhov kev tsav dav hlau loj dua, siv ntau dua strip dav thiab txo cov khoom siv.
• Txiav clearance- Tus qauv pib taw tes rau cov hlau me me yog kwv yees li 10% ntawm cov khoom tuab ntawm ib sab, tab sis qhov no hloov nrog qib. Siab dua - steels muaj zog tuaj yeem xav tau kev tshem tawm ntau dua 20% ntawm ib sab kom ua tiav cov shear huv thiab txo qis qhov siab.
• Pub kev ntseeg tau- Cov strips hnyav dua xav tau servo feeders muaj zog dua thiab siab dua strips los tiv thaiv misfeed. Cov strips nyias nyias, hloov pauv, yuav xav tau lub tshuab nqus tsev lossis cua- tshuab tshuab kom lawv tiaj tus tiv thaiv qhov chaw tuag ntawm cov hlab ntsha.

Kev sib cuam tshuam ntawm qib steel thiab thickness tsim ib tug matrix ntawm kev txwv uas txhua txhua hlau stamping tuag yuav tsum tau tsim nyob ib ncig ntawm. A 2 hli HSLA sawb ntawm 80 ksi tensile coj tsis muaj dab tsi zoo li 2 hli qis -carbon strip ntawm 45 ksi - txawm tias cov tuab zoo ib yam, cov xovxwm tonnage, clearances, thiab chaw nres tsheb suav yuav txawv.

Cov ntaub ntawv no - tsis muaj kev txwv tsis pub muaj nyob hauv kev sib cais. Lawv ntws ncaj qha mus rau hauv kev txiav txim siab tuag: muaj pes tsawg lub chaw yuav suav nrog, qhov twg yuav tso cov neeg tsav dav hlau, yuav ua li cas thiaj li ua tau raws li kev ua haujlwm, thiab ntau npaum li cas sawb dav los faib rau cov neeg nqa khoom choj. Txhua yam khoom vaj khoom tsev dhau los ua cov tswv yim tsim uas tsim cov qauv tsim ntawm tag nrho cov cuab yeej.

Progressive Die Design Considerations for Steel Parts

Txhua qhov kev tuag zuj zus pib yog qhov teeb meem tsim: ua li cas koj npaj ib ntu ntawm kev ua haujlwm raws li cov hlua hlau kom cov khoom siv, ib feem geometry, thiab kev lag luam kev lag luam tag nrho? Cov lus teb ua rau tag nrho cov cuab yeej - nws qhov ntev, chaw nres tsheb suav, strip dav, thiab thaum kawg nws tus nqi. Kev tsim cov tuag tsis zoo ua rau cov khoom tawg, cov cuab yeej ua tsis tiav, thiab cov khoom siv khib nyiab. Lub tswv yim tsim qauv hloov cov kev txwv tib yam mus rau hauv ib qho ntshiv, ruaj khov kho cov cuab yeej stamping uas ua tau zoo tshaj ntau lab lub voj voog.

Chaw nres tsheb suav thiab Sawb Layout Optimization

Muaj pes tsawg lub chaw nres tsheb yuav tsum tau ua tiav? Tsis muaj universal formula. Chaw nres tsheb suav yog tsav los ntawm ib feem geometry, yuav tsum tau ua haujlwm, thiab - thuam - qib steel lub formability txwv ib qho chaw nres tsheb. Ib qho yooj yim ca bracket nyob rau hauv 1010 steel nrog peb pierced qhov thiab ib tug khoov yuav tsum tau tsuas yog 4-5 noj. Ib qho nyuaj HSLA automotive structural ib feem nrog ntau khoov, embossments, thiab nruj kam rau ua yuav thov 15 los yog ntau tshaj.

Cov logic ua haujlwm zoo li no: txhua qhov kev ua haujlwm tsuas tuaj yeem lim cov khoom los ntawm tus nqi tsawg ua ntej tawg. Thaum ib qho kev khoov dhau ntawm cov hlau tsis muaj kev ruaj ntseg deformation pib, cov neeg tsim khoom faib nws hla ob qhov chaw nres tsheb nrog ib feem ntawm txhua qhov. Siab dua -lub zog lossis kev ua haujlwm- cov hlau tsis muaj zog tiv taus qhov deformation tsawg dua rau ib lub chaw nres tsheb, uas ncaj qha nce chaw nres tsheb suav.

Idle chaw nres tsheb - txoj haujlwm uas tsis muaj kev ua haujlwm tshwm sim - ua haujlwm rau lub hom phiaj kev tsim vaj tsev. Lawv muab cov cheeb tsam kev ntxhov siab uas cov sawb tuaj yeem faib cov residual strain ntawm kev xav tau cov theem. Lawv kuj txhim kho txoj hlua khi ruaj khov los ntawm kev tswj xyuas cov neeg nqa khoom zoo sib xws hauv web rigidity thoob plaws qhov ntev ntev. Tshawb nrhiav hauvstrip layout optimizationlees paub tias txo qis chaw nres tsheb thaum ua raws li ob qho kev txwv ua ntej (uas kev ua haujlwm yuav tsum tshwm sim ua ntej lwm tus) thiab cov kev txwv nyob ib puag ncig (uas kev ua haujlwm tsis tuaj yeem sib koom chaw nres tsheb vim qhov sib thooj) yog qhov tseem ceeb hauv kev txhim kho stamping tuag tsim.

Sawb dav optimization khiav mus rau qhov chaw nres tsheb npaj. Cov strips dav dav kom haum rau qhov loj dua lossis ntau kab (ob -ntaus layouts) tab sis pov tseg ntau cov khoom siv rau ib qho mob stroke. Cov neeg tsim qauv suav cov khoom siv raws li qhov piv ntawm cov cheeb tsam hauv cheeb tsam rau tag nrho cov sawb noj. Ib qhov dej zoo-kev ua kom zoo tshaj plaws rau kev tuag zuj zus feem ntau ua tiav 70-85% kev siv. Cov neeg nqa khoom txuas ntxiv - qhov nqaim webs txuas rau cov pob txha pob txha - yuav tsum yog qhov dav txaus kom muaj sia nyob ua rog tsis tawg, tshwj xeeb tshaj yog nyob rau hauv qis-ductility steels.

Tsim-rau-Manufacturability in Progressive Die Tooling

Hlau stamping tuag tsim kev txiav txim siab tau ua thaum lub sijhawm DFM tiv thaiv cov teeb meem uas yuav txwv tsis pub ntau txhiab teev rau hauv kev tsim khoom. Rau cov khoom hlau hauv kev tuag, ntau lub hauv paus ntsiab lus DFM muaj qhov tseem ceeb tshaj:

• Yam tsawg kawg nkaus qhov sib nrug- Qhov thiab qhov txiav tau muab tso ze dhau ua ke tsim cov seem tuag tsis muaj zog ntawm cov xuas nrig ntaus. Txoj cai dav dav: tuav tsawg kawg ob zaug cov khoom tuab ntawm cov yam ntxwv uas nyob ib sab. Hauv siab - steels muaj zog, qhov tsawg kawg nkaus nce vim tias qhov siab txiav quab yuam ua rau muaj kev ntxhov siab ntau dua ntawm qhov nqaim tuag.
• Grain direction alignment- Hlau sawb muaj cov kev taw qhia dov uas cuam tshuam rau ductility. Khoov oriented perpendicular mus rau grain zam nruj dua radii yam tsis muaj cracking. Progressive stamping tuag tsim yuav tsum ua raws cov kev khoov tseem ceeb ntawm cov kab nrib pleb dov, uas txhais tau hais tias ib feem kev taw qhia nyob rau hauv lub strip layout dhau los ua kev txiav txim siab, tsis yog ib qho yooj yim nesting.
• Choj dav nyob rau hauv lub carrier strip- Cov choj tuav ib feem ntawm txoj hlua mus txog thaum kawg txiav tawm. Nqaim dhau lawm thiab lawv tsim kua muag thaum lub sij hawm tsim, tso ib feem ua ntej. Dav dav heev thiab lawv nkim khoom. Choj dav nyob ntawm strip thickness, tensile zog, thiab qhov hnyav ntawm kev tsim rog ntawm cov chaw nyob ib sab.
• Internal khoov radii- Cov lus qhia dav dav tau teeb tsa qhov tsawg kawg ntawm lub vojvoog khoov sib npaug los yog siab dua cov khoom tuab (R Ntau dua lossis sib npaug rau T). Mus sharper tsub kom muaj kev ntxhov siab concentration, ua rau tawg nyob rau hauv ib feem thiab tsis ua hauj lwm ntxov ntxov nyob rau hauv daim ntawv hlau stamping tuag.

Pilot pin placement yog lwm DFM-kev txiav txim siab tseem ceeb. Cov kws tsav dav hlau yuav tsum tau muab tso rau ntawm qhov sib npaug ntawm cov kab nrib pleb, nyiam dua nyob rau hauv cov chaw nqa khoom hauv lub vev xaib es tsis yog hauv kev ua haujlwm geometry. Lawv qhov chaw txheeb ze rau kev tsim cov chaw nres tsheb txiav txim siab ntau npaum li cas qhov kev ua haujlwm yuam kev sib sau ua ke ntawm kev ua haujlwm. Tso cov neeg tsav dav hlau tam sim ua ntej siab - chaw nres tsheb qhov tseeb - es tsis yog tso siab rau kev tso npe los ntawm cov chaw nres tsheb ua ntej hauv ntu - ua kom qhov tseeb qhov tseeb qhov tseem ceeb tshaj plaws.

CAD/CAM thiab Simulation hauv Die Design

Xav txog kev tsim 12-chaw nres tsheb tuag, khiav koj thawj qhov kev sim ntau lawm, thiab nrhiav pom qhov chaw nres tsheb 8 tawg vim tias ua haujlwm nyuaj los ntawm cov chaw ua ntej dhau qhov kev kwv yees. Qhov xwm txheej ntawd tau siv nyiaj ntau lub lis piam thiab ntau txhiab daus las. Niaj hnub nimno nce qib tuag tsim software tshem tawm ntau qhov kev pheej hmoo ua ntej cov cuab yeej steel yog machined.

Finite Element Analysis (FEA) simulates cov ntaub ntawv ntws los ntawm txhua qhov chaw nres tsheb ua ntu zus, kwv yees thinning, strain faib, thiab kev pheej hmoo tawg. Rau cov hlau, kev twv ua ntej springback yog qhov tseem ceeb tshwj xeeb tshaj yog - simulation suav ntau npaum li cas txhua qhov kev tsim tshwj xeeb rebounds tom qab cov xovxwm qhib, tso cai rau cov engineers los them nyiaj rau qhov tuag geometry thaum lub sij hawm tsim es tsis yog los ntawm kev sim kim heev - thiab - yuam kev hauv xovxwm. Raws li Manor Tool qhia, FEA tuaj yeem txheeb xyuas qhov kev pheej hmoo tawg ua ntej lub cuab yeej tsim, txuag ntau dua $ 20,000 hauv cov nqi rov ua haujlwm thiab tshem tawm lub limtiam ntawm kev xa tawm qeeb ntawm ib qhov project.

Platforms xws li Cimatron, AutoForm, thiab Dynaform tso cai rau cov neeg tsim qauv tsim kom muaj ib daim kab xev ua tiav digitally, tom qab ntawd khiav kev simulations thoob plaws txhua qhov chaw ua ntu zus.AutoForm's strip layout toolscia cov neeg siv txhais ib los yog ob npaug - ib feem layouts, sib piv cov kev xaiv zes, thiab txo cov khoom siv - tag nrho thaum validating formability. Lub caij no, Logopress3 thiab cov SolidWorks zoo sib xws-raws li cov tshuab muaj cov khoom siv sib xyaw ua ke rau cov txheej txheem tuag xws li cov nqa, cov tsav tsheb, thiab cov neeg tuav pov hwm, ua kom cov ncauj lus kom ntxaws.

Cov txiaj ntsig siv tau yog tsawg dua tsim iterations. Yog tsis muaj simulation, ib tug complex stamping tuag tsim yuav xav tau peb los yog plaub lub cev sim ua ntej ntau lawm -npaj geometry raug kaw. Nrog rau kev siv tau FEA, feem ntau cov kev pab cuam ncav cuag kev tsim khoom ruaj khov hauv ib lossis ob qhov kev sim - ib qho kev txo ncaj qha rau ob qho tib si tus nqi thiab lub sijhawm tso tawm. Cov kev txiav txim siab engineering tau ua thaum lub sijhawm kev lees paub digital no tau tsav mus txog 80% ntawm tag nrho cov nqi tsim khoom, ua rau simulation peev ib qho ntawm qhov siab tshaj plaws - rov qab ua haujlwm hauv txhua qhov kev pab cuam tuag.

Kev txiav txim siab tsim qauv tsim cov ciam teb ntawm qhov kev tuag zuj zus tuaj yeem tsim tau. Tab sis nyob rau hauv cov ciam teb no, nws yog ib tug neeg chaw nres tsheb ua hauj lwm - txiav, sib sau, dabtsi yog khoov - uas hloov tiaj tus steel sawb mus rau lub functional geometry. Yuav ua li cas cov kev khiav hauj lwm yog sequenced, thiab yog vim li cas qhov sequences tseem ceeb rau steel tshwj xeeb, txiav txim seb cov khoom tawm los yog tawm los ntawm seem.

Kev ua haujlwm tseem ceeb ntawm txhua qhov chaw tuag

Txhua qhov chaw nres tsheb hauv qhov kev vam meej tuag muaj ib txoj haujlwm - tab sis qhov kev txiav txim uas cov haujlwm ntawd tshwm sim tsis yog qhov kev txiav txim. Qhov sib lawv liag ua raws li lub hauv paus ntsiab lus ntawm yuav ua li cas steel deforms, yuav ua li cas qhov ntev hloov nyob rau hauv kev ntxhov siab, thiab yuav ua li cas rau npe yuav tsum tau khaws cia los ntawm thawj ntaus mus rau qhov kawg txiav tawm. Tau qhov kev txiav txim tsis ncaj ncees lawm thiab koj yuav tawm tsam burrs, tawg, thiab seem drift rau lub neej ntawm lub cuab yeej. Tau txais nws txoj cai thiab lub stamping tuag ua qhov zoo sib xws ntawm qhov nrawm nrog kev cuam tshuam tsawg.

Txiav thiab tho kev ua haujlwm

Kev txiav cov haujlwm feem ntau yog thawj cov chaw nres tsheb thaum ntxov ntawm kev tuag. Vim li cas? Vim tias tshem tawm cov khoom ua ntej tsim nws yog qhov tswj tau ntau dua li sim tho los yog khoob tom qab lub sawb twb tau khoov los yog kos rau hauv peb -seem geometry. Flat strip nthuav tawm ib qho kev sib xws, qhov pom tau zoo rau cov cuab yeej xuas nrig ntaus, uas txhais tau hais tias kev ntxuav kom huv, qhov siab zoo sib xws, thiab lub neej ntev dua.

Feem ntau cov haujlwm txiav rau steel qhov chaw suav nrog:

• Piercing- tsim cov qhov hauv, qhov, lossis cov yam ntxwv siv cov ntawv hlau xuas nrig ntaus uas thawb cov khoom los ntawm kev sib tw tuag qhib. Pilot qhov yuav luag ib txwm pierced ntawm chaw nres tsheb ib qho los tsim kev sau npe rau txhua qhov haujlwm tom ntej.
• Ncua tseg- txiav qhov profile sab nrauv ntawm ib feem (lossis ib feem ntawm nws) los ntawm kab txaij. Nyob rau hauv kev tuag, ib nrab blanking ntawm cov chaw thaum ntxov thiab zaum kawg blanking ntawm qhov chaw nres tsheb kawg yog ib txwm.
• Lancing- txiav thiab khoov ib lub tab lossis louver nyob rau hauv ib qho hlab ntsha tawg yam tsis muaj kev sib cais tag nrho ntawm cov sawb. Feem ntau siv los tsim cov yam ntxwv txuas los yog cov qhov cua nkag.
• Ntshai- tshem tawm cov khoom tawm ntawm ntug ntug los tsim kev tshem tawm kev ua haujlwm tom qab cov chaw nres tsheb lossis txhawm rau txheeb xyuas cov txheej txheem ua ntu zus.
• Txiav- tshem tawm cov khoom ntau dhau tom qab tsim, feem ntau tom qab cov chaw nres tsheb uas tsim cov yam ntxwv xav tau qhov kawg ntug profileing.

Steel hardness ncaj qha cuam tshuam li cas cov kev txiav no ua. Rau feem ntau cov pa roj carbon steel, zoo punch - mus rau - tuag clearance ranges ntawm 5-10% ntawm cov khoom thickness ntawm ib sab. Cov hlau hnyav dua - HSLA qib lossis ua haujlwm- cov hlau tsis muaj zog - yuav tsum tau nruj dua kom tshem tawm kom tsis txhob muaj ntau dhau ntawm rollover thiab burr tsim, qee zaum poob rau 3-5% ntawm ib sab. Mus nruj heev accelerates punch hnav thiab nce stripping rog. Mus dhau xoob ua rau cov npoo ragged thiab cov burrs loj heev uas yuav tsum tau ua kom deburring.

Thickness tseem ceeb heev. A 2 hli qis- carbon steel sawb hu rau kwv yees li 0.10-0.20 hli tshem tawm ib sab. Tib lub thickness nyob rau hauv 304 stainless tej zaum yuav xav tau tsuas yog 0.08-0.12 hli vim hais tias lub zog shear ntau dua ua ib tug huv fractures cheeb tsam ntawm tighter clearances. Cov lej no hloov cov geometry ntawm txhua qhov tuag txiav hlau feature hauv lub cuab yeej, cuam tshuam cov punch grind profiles, tuag khawm tho qhov ntev, thiab qhov zaus ntawm kev sib tsoo.

Kev tsim thiab khoov kev ua haujlwm

Thaum lub qhov pierced thiab profiles yog ib feem tsim, lub sawb txav mus rau hauv kev ua ib cheeb tsam. dabtsi yog khoov, kos duab, npib, embossing, thiab extruding chaw reshape ca steel rau hauv peb -dimensional geometry - thiab txhua tus muaj cov kev cov nyom tshwj xeeb thaum ua hauj lwm nrog steel cov elastic rov qab tus cwj pwm.

Khoovyog qhov kev ua haujlwm ntau tshaj plaws hauv kev ua haujlwm stamping tuag. Hlau strips yog khoov dua ib lub vojvoog punch tiv thaiv qhov thaiv tuag los tsim flanges, tabs, channels, thiab brackets. Qhov teeb meem tseem ceeb? Springback. Txhua lub steel khoov ib nrab unloads thaum lub xovxwm qhib, thiab lub kaum sab xis ntawm lub kaum sab xis ntawm lub tiaj tus. Lub zog siab zog steels caij nplooj ntoos hlav rov qab ntau dua - cov hlau me me tuaj yeem rov qab 1-2 degrees ntawm 90-degree khoov, thaum HSLA steels tuaj yeem rov qab 5-8 degrees lossis ntau dua.

Cov tswv yim them nqi kho mob hauv qhov tuag muaj xws li:

• Overbending- tsim yav dhau los lub hom phiaj lub kaum sab xis ces springback coj ib feem rov qab rau spec. Qhov no yog qhovfeem ntau siv cov txheej txheem them nyiajvim nws txoj kev yooj yim thiab siv tau thoob plaws feem ntau cov kev ua haujlwm bending.
• Npib- siv lub zog siab hauv zos ntawm qhov khoov apex rau plastically deform cov khoom los ntawm nws cov tuab tuab, tshem tawm elastic rov qab zoo. Kev npib yuav tsum muaj ntau dua tonnage tab sis ua kom nruj dua angular tolerances.
• Kauj ruam dabtsi yog khoov- decomposing ib tug loj - lub kaum sab xis khoov mus rau ntau yam me me - lub kaum sab xis increments nyob rau hauv successive chaw nres tsheb, ua rau cov yas deformation piv thiab txo net elastic rov qab.

Kev kos duabcov chaw nres tsheb rub lub sawb mus rau hauv kab noj hniav los ua khob, recesses, los yog plhaub. Steel lub ductility txwv qhov tob tob npaum li cas tuaj yeem mus rau ib qho chaw nres tsheb - tshaj li ntawm 40-50% kos piv rau hauv ib qho kev pheej hmoo ua rau nyias nyias lossis tawg. Kev sib sib zog nqus nqus tau sib cais thoob plaws ntau qhov chaw nres tsheb nrog kev nce qhov tob.

Embossingtsim ntiav tsa los yog recessed nta - tav, logos, stiffening hlaws - los ntawm displaced khoom nyob rau hauv lub zos yam tsis tau txiav.Extrudingthawb cov khoom siv los ntawm qhov qhib me me los tsim cov thawj coj lossis cov dab tshos, feem ntau siv los tsim cov xov mounting nta hauv ib qho kev tuag stroke.

Chaw nres tsheb Sequencing Logic rau Steel Parts

Vim li cas qhov kev txiav txim ua haujlwm tseem ceeb heev? Peb lub hauv paus ntsiab lus tswj hwm kev nce qib tuag chaw nres tsheb sequencing:

Piercing precedes sib sauvim tias txoj hlua tiaj tiaj ua rau qhov chaw qhov tseeb dua. Thaum lub sawb yog khoov, lub deformed geometry ua rau nws yuav luag tsis yooj yim sua rau tho qhov hauv lawv txoj haujlwm kawg. Qhov uas yuav tsum tshwm sim nyob rau hauv cov cheeb tsam tsim yog pierced thaum lub sawb tseem tiaj tus, ces nqa mus rau hauv txoj hauj lwm los ntawm kev ua hauj lwm tom ntej.

Qhov tseem ceeb ntawm qhov ntev yog tsim tom qab tsim tiav.Yog hais tias ib tug feature dimension yog hais los ntawm ib tug tsim nto, lub forming yuav tsum tshwm sim ua ntej - txwv tsis pub springback thiab cov ntaub ntawv ntws yuav hloov lub feature tawm ntawm kam rau ua. Qhov no zoo li tsis sib haum rau thawj lub hauv paus ntsiab lus, thiab qhov nro ntawd yog vim li cas qhov kev tsim kho tuag yuav tsum tau ua tib zoo soj ntsuam xyuas. Txoj kev daws teeb meem feem ntau yog txhawm rau tho kev tsav tsheb thiab tsis yog- qhov tseem ceeb thaum ntxov, tsim ib feem, tom qab ntawd ua qhov tseeb qhov tseeb tho los yog ntsuas qhov chaw tom qab.

Pilot qhov tuav sau npe thoob plaws.Los ntawm chaw nres tsheb ib rau pem hauv ntej, pilot pins koom lub sawb ntawm txhua tus mob stroke. Tag nrho cov kev khiav hauj lwm tom qab siv cov kev tsav dav hlau no, uas txhais tau hais tias lawv qhov kev tso kawm qhov tseeb txiav txim siab qhov tseeb ntawm tag nrho ib feem. Cov kws tsav dav hlau yeej ib txwm tho qhov chaw nres tsheb ntxov tshaj plaws - feem ntau yog thawj zaug - thiab tseem nyob hauv qhov chaw thauj tog rau nkoj rau tag nrho cov stamping tuag Cheebtsam uas ua raws.

Ntawm no yog ib qho chaw nres tsheb ib ntus rau steel mounting bracket nrog ob lub qhov, ib tug bent flange, thiab ib tug stiffening tav:

1. Pierce pilot qhov nyob rau hauv lub carrier sawb
2. Pierce functional qhov (mounting slots, nyem notches)
3. Notch strip edges los txhais ib feem txheej txheem
4. Emboss stiffening tav thaum sawb tseem tiaj tus
5. Idle chaw nres tsheb (kev ntxhov siab nyem, strip stabilization)
6. Khoov flange rau lub hom phiaj lub kaum sab xis ntxiv rau overbend them nyiaj
7. Npib los yog retrike flange rau zaum kawg angular kam rau ua
8. Kev txiav tawm zaum kawg - cais ib feem ntawm cov khoom thauj

Cov kab ke no qhia txog txoj cai dav dav: cov cuab yeej siv hlau xuas nrig ntaus thiab txiav cov haujlwm ua haujlwm nyob rau hauv pem hauv ntej ntawm qhov tuag, kev ua haujlwm ua haujlwm puv qhov chaw nruab nrab thiab tom qab, thiab kev sib cais zaum kawg ib txwm los txog. Idle chaw nres tsheb tshwm nyob qhov twg cov sawb xav tau ib tug breather ntawm hnyav forming theem - tshwj xeeb tshaj yog tseem ceeb rau steels uas muaj kev ua hauj lwm siab- hardening tus nqi uas residual stress buildup hem downstream formability.

Txhua qhov chaw nres tsheb cov cuab yeej hnav ntawm tus nqi sib txawv nyob ntawm seb nws ua dab tsi thiab nyuaj npaum li cas cov hlau thawb rov qab. Cov chaw txiav degrade los ntawm abrasive punch hnav. Cov chaw tsim khoom raug kev txom nyem los ntawm galling thiab qaug zog. Tus qauv hnav ntawd - thiab koj tswj nws li cas - yog qhov kawg txiav txim siab seb tus tuag khiav rau 100,000 hits lossis 10 lab.

Tuag tu thiab cuab yeej lub neej thaum Stamping hlau

Kev tuag zuj zus tsis ua tiav ib zaug. Nws degrades maj mam - punch npoo dull, tsim radii roughen, clearances qhib - thiab ib feem zoo drifts nrog rau nws. Cov hlau ua kom qhov degradation no ntau dua li cov ntaub ntawv softer vim tias nws lub zog shear ntau dua, ua haujlwm -cov cwj pwm tawv tawv, thiab cov oxides saum npoo. Qhov sib txawv ntawm lub stamping tuag teeb uas khiav kev ntseeg siab rau ntau lab lub voj voog thiab ib qho uas yuav tsum tau muaj kev cuam tshuam tas mus li los mus rau peb yam: kev nkag siab txog kev hnav li cas, kev tswj cov cuab yeej ntawm lub sijhawm es tsis yog tom qab tsis ua haujlwm, thiab xaiv cov khoom siv zoo rau txhua qhov chaw nres tsheb qhov kev xav tau tshwj xeeb.

Hnav cov qauv thiab tsis ua haujlwm hom hauv Steel Stamping Tuag

Thaum koj tab tom khiav hlau los ntawm kev tuag zuj zus ntawm kev tsim khoom nrawm, tsib lub zog tsis ua haujlwm sib tw los rhuav tshem koj cov cuab yeej. Txhua qhov kev txhim kho sib txawv nyob ntawm qib steel raug stamped, thiab txhua tus yuav tsum muaj kev ntsuas sib txawv. Tshawb nrhiav los ntawmAHSS Kev Tshawb Fawbtxheeb xyuas cov qauv tseem ceeb no xws li hnav (abrasive thiab nplaum), yas deformation, chipping, cracking, thiab galling.

Abrasive hnavyog hom degradation feem ntau hauv steel stamping tuag. Cov khoom tawv tawv - zeb nplai ntawm kub- dov steel, carbides nyob rau hauv siab - qib zog, los yog ua hauj lwm- cov khib nyiab tawv los ntawm kev txiav yav dhau los - ua zoo li lub tshuab sib tsoo lub log tawm tsam cov punch thiab tuag nto. Txhua tus mob stroke tshem tawm me me ntawm cov khoom siv, maj mam ua kom pom tseeb thiab ua kom qhov siab burr. Qhov nyuaj ntawm cov hlau workpiece, qhov hnav abrasive sai zuj zus. HSLA thiab dual-theem steels nrog lub zog tensile siab tshaj 590 MPa tuaj yeem hnav cov punches ntawm tus nqi plaub mus rau tsib zaug sai dua cov hlau me me.

Adhesive hnav thiab gallingnthuav tawm ib qho kev sib tw sib txawv, tshwj xeeb tshaj yog nrog cov hlau tsis muaj zog stamping. Kev sib txhuam thiab cua sov tsim tawm raws li austenitic stainless swb hla cov cuab yeej nto tsim micro-welds ntawm daim ntawv thiab tuag. Thaum cov ntawv cog lus no tawg, cov khoom hloov pauv ntawm ib qho chaw mus rau lwm qhov - feem ntau los ntawm qhov chaw softer mus rau ib qho nyuaj. Qhov kev tsim tawm no (galling) khawb cov khoom tom qab thiab ua kom nrawm ntxiv rau hauv tus kheej - txhawb nqa lub voj voog. Raws liTus Fabricatorsau ntawv, polishing cov cuab yeej nto ua ntej thiab tom qab txheej yuav pab txo qis galling, thaum huab cua -lub siab lubricants ua qhov tseem ceeb rau kev tswj cov kev sib cuag nrog kev sib cuag.

Chipingtshwm sim los ntawm cyclic stresses tshaj lub zog qaug zog ntawm cov khoom siv, feem ntau ntawm cov ntse txiav npoo. Microcracks nucleate, propagate nrog rov ua dua, thiab nws thiaj li ua rau cov khoom me me tawg tawm ntawm cov punch lossis tuag npoo. Steel qhov siab dua shear resistance amplifates qhov cuam tshuam kev poob siab ntawm kev tawg thaum lub sij hawm tho, ua chipping ntau dua nyob rau hauv cov chaw txiav uas ua cov qib thicker lossis muaj zog dua.

Kev tawgtshwm sim thaum muaj kev ntxhov siab tshaj qhov tawg toughness ntawm cov cuab yeej hlau. Cov ntsiab lus kev ntxhov siab - cov cim sib tsoo, cov kaum ntse ntse sab hauv, lossis cov qauv tsim nrog cov radii tsis txaus - pib cov kab nrib pleb uas nthuav tawm kev puas tsuaj loj. Ib cov ntaub ntawv tshawb fawb tau sau tseg D2 cov cuab yeej hlau tawg tom qab tsuas yog 5,000-7,000 lub voj voog thauj khoom thaum tsim 580 MPa ferrite-bainite steel, piv rau 50,000-lub voj voog lub neej tib yam cuab yeej ua tiav nrog cov qib pa.

Yas deformationtshwm sim thaum kev sib cuag siab tshaj cov khoom siv lub zog compressive yield zog. Siab dua - lub zog steels concentrate ntau load rau ntawm qhov chaw me me - tshwj xeeb tshaj yog nyob rau ntawm kos radii thiab coining stations - ua rau tuag nto mus nceb los yog indent. Thaum deformation pib, qhov hloov pauv geometry ua rau muaj kev ntxhov siab ntau dua hauv zos, ua rau muaj kev puas tsuaj ntxiv.

Cov hom kev ua haujlwm no tsis tshua muaj tshwm sim hauv kev sib cais. Adhesive hnav ua rau cov tawv nqaij tawv uas ua rau muaj kev ntxhov siab, pib chipping. Chiped npoo tsim cov khoom tsis sib xws uas ua rau kom tawg. Paub tias hom twg yog tus tswj hwm ntawm txhua qhov chaw nres tsheb - thiab kev sib txuas lus rau koj cov cuab yeej steel khoom siv - yog lub hauv paus ntawm txhua qhov kev txhim kho zoo stamping tuag.

Kev Tiv Thaiv Kev Tiv Thaiv Kev Teem Caij thiab Sib Nqus Sib Nqus

Tos kom txog thaum qhov chaw zoo li tsis zoo rau kev pabcuam tuag yog qhov kev saib xyuas kim tshaj plaws muaj. Los ntawm lub sij hawm burrs pom ntawm qhov muag liab qab, xuas nrig ntaus tau ua tiav zoo dhau los ntawm qhov zoo tshaj plaws sharpening point - lub ntsiab lus ntau cov ntaub ntawv yuav tsum tau muab tshem tawm thaum lub sij hawm regrinding, uas shortens tag nrho cov cuab yeej lub neej thiab tsub kom hloov zaus.

Kev tiv thaiv zoo pib nrog kev ntsuas lub hom phiaj es tsis yog kev txiav txim siab pom. Burr qhov siab yog thawj qhov taw qhia: feem ntau precision stamping kev ua haujlwm ua rau rov ua kom rov zoo dua thaum burrs tshaj 10% ntawm cov khoom tuab. Rau 1 hli steel sawb, qhov chaw pib tsuas yog 0.1 hli - NW nyuam qhuav perceptible tsis magnification tab sis kom meej meej ntsuas nrog ib tug burr gauge los yog optical comparator.

Ntaus suav taug qab muab lub sijhawm teem sijhawm. Txhua lub stamping tuag teeb yuav tsum muaj cov ntaub ntawv hauv paus: tus naj npawb ntawm strokes ib qho chaw nres tsheb feem ntau khiav ua ntej burr qhov siab mus txog qhov pib txij nkawm. Cov ntu no sib txawv ntawm qhov chaw nres tsheb thiab qib steel:

• Piercing chaw nres tsheb hauv cov hlau me me (1008-1010)- feem ntau 150,000 txog 250,000 hits ntawm sharpenings
• Piercing chaw nres tsheb hauv stainless hlau (304, 316)- nquag 50,000 txog 100,000 hits vim yog nplaum hnav thiab galling
• Piercing chaw nres tsheb hauv HSLA steel (590+ MPa)- qee zaum qis li 30,000 txog 80,000 hits nyob ntawm thickness thiab txheej
• Tsim cov chaw nres tsheb- tau tshuaj xyuas nyob rau lub sijhawm zoo sib xws tab sis tau txais kev pabcuam raws li qhov chaw saum npoo es tsis yog ntug sharpness

Tus nqi pauv -tawm ntawm kev saib xyuas tau teem tseg thiab tsis tau npaj tseg yog qhov tsis txaus ntseeg. Qhov kev npaj sharpening yuav siv sij hawm qhov tuag offline rau cov sij hawm thiab tshem tawm ib tug tswj tus nqi ntawm cov cuab yeej cuab tam (feem ntau 0.05-0.15 mm rau ib grind). Ib qho kev npaj tsis tau ua tiav - cov punch tawg, ntu ntu tuag, lossis qhov chaw ua haujlwm galled - tuaj yeem kaw cov khoom siv rau hnub thaum hloov cov khoom tsim, hardened, thiab haum. Tshaj li tus nqi qis qis ncaj qha, kev puas tsuaj loj feem ntau ua rau cov chaw nres tsheb uas nyob ib sab, tig ib qho - cov khoom siv kho dua tshiab rau hauv ntau lub chaw nres tsheb.

Stamping tuag lifters - lub caij nplooj ntoos hlav -loaded Cheebtsam uas tsa lub sawb ntawm strokes kom nws thiaj li mus tau dawb do - kuj yuav tsum tau teem sijhawm soj ntsuam. Hnav los yog tawg lifters tso cai rau lub sawb rub hla qhov chaw tuag qis thaum pub mis, tsim kev khawb, cov xwm txheej tsis zoo, thiab ua kom nrawm nrawm ntawm cov chaw nres tsheb hauv qab. Lifter caij nplooj ntoos hlav qaug zog yog tshwj xeeb tshaj yog muaj nyob rau hauv siab - kev khiav hauj lwm ceev uas ntau lab lub voj voog sib sau sai. Nrog rau kev tshuaj xyuas lifter nyob rau hauv txhua lub qhov rais tu ncua tiv thaiv cov kev ua tsis tiav thib ob los ntawm cascading los ntawm kev tuag.
