Strip layout optimization thaum kawg txiav txim siab npaum li cas ib qho kev nce qib tuag hloov cov coil nyoos rau hauv cov khoom tiav. Tab sis qhov kev teeb tsa nws tus kheej tsis tuaj yeem ua tiav yam tsis tau nkag siab tias cov khoom siv coj li cas hauv kev ntxhov siab - nws txoj kev nyiam caij nplooj ntoos hlav, nws txoj kev txwv, thiab nws txoj kev kam rau lub zog ntawm txhua qhov chaw nres tsheb siv.

Kev xaiv cov khoom siv thiab nws cuam tshuam rau Progressive Die Design

Lub strip layout qhia koj qhov chaw ua haujlwm tshwm sim. Cov ntaub ntawv qhia koj nyuaj npaum li cas cov haujlwm ntawd ntaus. Txhua qhov kev tshem tawm qhov ntev, txhua qhov kev kwv yees kwv yees, txhua lub vojvoog tsim nyob rau hauv qhov kev vam meej tuag rov qab mus rau ib lo lus nug: dab tsi hlau khiav los ntawm cov cuab yeej no? Hloov qis- carbon hlau rau stainless thiab koj lub zog punch tuaj yeem ua ob npaug. Hloov mus rau txhuas thiab koj lub caij nplooj ntoos hlav- rov qab them nyiaj hloov tag nrho. Hauv kev nce qib hlau stamping, cov khoom siv tsis yog qhov sib txawv ntawm qhov koj ntsaws rau qhov kawg - nws hloov kho tag nrho cov hlau stamping tuag tsim los ntawm thawj daim duab kos.

Yuav Ua Li Cas Cov Khoom Siv Ua Haujlwm Ua Kom Muaj Zog thiab Kev Xam Xaj

Tuag clearance - qhov sib txawv ntawm punch thiab tuag khawm - yog qhia raws li ib feem pua ​​ntawm cov khoom thickness ntawm ib sab. Tab sis qhov feem pua ​​​​hloov pauv tau zoo raws li cov hlau koj txiav. Rau me me hlau, tuag designers feem ntau siv10% rau ib sabraws li tus qauv pib taw tes. Stainless hlau, txawm li cas los xij, coj txawv txawv: 10% kev tshem tawm ua rau qhov phem tshaj plaws qhov siab ntawm austenitic qib. Advanced siab -lub zog steels yuav xav tau kev tshem tawm txog li 21% ib sab rau qhov zoo tshaj plaws ntug.

Kev quab yuam kom ua raws li tus qauv zoo sib xws. Cov pa roj carbon steel nce qib stamping ntawm qis- cov qib carbon teeb tsa lub hauv paus. Ferritic stainless hlau zoo li Hom 430 xav tau kwv yees li 50% ntau dua qhov tsis muaj lub siab, thaum qib austenitic xws li 304 thiab 316 tuaj yeem xav tau txog li peb npaug ntawm qhov qis - carbon hlau. Rau npib tsib xee thiab cobalt alloys, cia siab tias 30-50% ntau lub zog nias dua hlau - thiab qee qhov tungsten alloys thawb mus rau 100% ntau dua.

Cov lus hauv qab no qhia tau hais tias yuav ua li cas cov ntaub ntawv tseem ceeb stamping txhais ua cov qauv tsim tshwj xeeb:

Koj yuav pom tias cov nqi zog ua haujlwm siab dua cuam tshuam nrog cov kev xav tau loj dua thiab ntau dua cov xovxwm tonnage. Qhov no tsis yog coincidental - cov ntaub ntawv uas harden sai heev thaum lub sij hawm deformation tiv thaiv slug breakout ntau aggressively, xav tau ntau mechanical leverage los shear kom huv si. Progressive tuag hlau stamping rau kev ua haujlwm siab- hardening alloys kuj tseem ua rau cov cuab yeej hnav, ua kom luv luv ntawm cov voj voog sib tw.

Thin Foil vs Thick Plate Design Strategies

Cov ntaub ntawv tuab hloov ntau dua li cov lej yuam kev - nws hloov tag nrho cov qauv tsim qauv. Nyias foils nyob rau hauv 0.5mm tam sim no cov kev cov nyom nyob ib ncig ntawm strip flatness, pub precision, thiab susceptibility rau distortion. Stripper daim hlau yuav tsum yog caij nplooj ntoos hlav- loaded nrog ua tib zoo calibrated siab: ntau dhau quab yuam buckles lub sawb, tsawg dhau lawm cia nws nqa nrog lub punch thiab misfeed. Pilot pins dhau los ua qhov tseem ceeb rau kev sau npe vim tias daim kab xev tsis muaj qhov nruj rau nws tus kheej -txoj kev khiav dej num raug.

Cov phaj tuab saum toj no 3 hli viav vias qhov kev sib tw nyob rau hauv qhov sib txawv. Feed mechanisms xav tau ntau tuav lub zog. Kev tsim cov haujlwm tsim muaj ntau dua tonnage, thiab cov qauv tuag yuav tsum nqus cov khoom ntawd yam tsis muaj deflection. Cov feem pua ​​​​ntawm kev tshem tawm yuav nruj me ntsis rau cov ntaub ntawv tuab dua los tiv thaiv slug rub, thiab cov blocks tuag xav tau cov kab kev txhawb zog ntau dua. Feem ntau cov tuag tuag ua tau zoo nyob rau hauv 0.2mm mus rau 3mm qhov chaw qab zib qhov twg pub raug thiab tsim rog nyob sib npaug.

Caij nplooj ntoos hlav-Kev them nyiaj rov qab los ntawm cov khoom siv

Caij nplooj ntoos hlav- rov qab yog cov khoom siv lub cim xeeb elastic - nws txoj kev nyiam ib nrab tsis khoov tom qab lub punch retracts. Txhua hlau springs rov qab, tab sis qhov℃txawv enormously. Stainless hlau springs rov aggressively vim nws siab yield - mus rau - tensile ratio thiab ua hauj lwm hardening cwj pwm. Aluminium nce qib stamping nthuav qhia qhov sib txawv: lub caij nplooj ntoo hlav nruab nrab- rov qab ua ke nrog anisotropic tus cwj pwm txhais tau hais tias khoov cov ces kaum nyob ntawm ntau qhov kev taw qhia ntawm cov nplej txheeb ze rau txoj kab khoov.

Brass kev vam meej stamping nyhav mus rau lub caij nplooj ntoos hlav qis dua- rov qab rau hauv kev npau taws, ua rau nws zam txim rau ntau yam - khoov qhov chaw hauv cov khoom sib txuas thiab cov khoom siv. Phosphor bronze, los ntawm qhov sib txawv, tuaj yeem tso saib cov kev taw qhia tseem ceeb tom qab dov, uas cuam tshuam li cas cov neeg tsim qauv taw qhia qhov chaw nyob rau hauv lub strip layout.

Cov neeg tsim qauv them nyiaj rau lub caij nplooj ntoos hlav- rov qab los ntawm kev sib tw dhau - txhob txwm ua dhau los ntawm lub hom phiaj lub kaum sab xis kom cov khoom so rau hauv qhov tshwj xeeb. Lub overbend lub kaum sab xis txawv ntawm cov khoom, khoov vojvoog, thiab thickness. Niaj hnub nimno CAE simulation kwv yees lub caij nplooj ntoos hlav- rov qab nrog qhov tseeb txaus los teeb tsa qhov tseem ceeb tshaj plaws ua ntej kev sim, tab sis kev hloov pauv ntawm thawj zaug - tsab xov xwm khiav tseem yog tus qauv coj ua. Qee qhov kev txhim kho kev tuag zoo sib xws suav nrog cov khoom siv kho tau ntawm qhov chaw khoov, tso cai kom zoo - kho lub kaum sab xis them nyiaj raws li cov khoom siv ntau yam sib txawv yam tsis siv cov cuab yeej hardened.

Cov khoom siv tsis yog cuam tshuam rau ib tus neeg tsim qauv chaw nres tsheb nkaus xwb - lawv txwv qhov ua tau raws li geometrically hauv thawj qhov chaw. Kev sib cuam tshuam ntawm kev tsim cov kev txwv, qhov tsawg kawg yog khoov radii, thiab kev kam rau siab stacking hla ntau lub chaw nres tsheb txhais ib thaj tsam uas cais cov qauv tsim los ntawm kev xav tau.

• Khoov- rau- qhov tshem tawm- Khaws qhov qhov tsawg kawg yog 2.5x thickness ntxiv rau qhov khoov vojvoog kom deb ntawm txoj kab khoov. Yog tias qhov kev ncua deb tsis tuaj yeem tswj tau, punch lub qhov tom qab khoov hauv qhov chaw nres tsheb tom qab.
• Kos qhov tob txwv- Ua ntej- kos qhov tob yuav tsum tsis pub tshaj 40-50% ntawm txoj kab uas hla ntawm lub cylindrical. Kev nce qib tsis muaj qhov nruab nrab annealing txwv txhua qhov txo qis ntxiv, feem ntau mus rau 20-30% ib qho chaw nres tsheb.
• Tab thiab qhov dav- Yam tsawg kawg tab lossis qhov dav yog 1.5x cov khoom tuab. Narrower nta deform nyob rau hauv stripping rog los yog buckle thaum pub mis.
• Lub tiaj tiaj nruab nrab ntawm cov nta- Khaws tsawg kawg 3x cov khoom tuab ntawm cov qauv tsim los tiv thaiv kev cuam tshuam kev cuam tshuam.

Cov theem pib no tsis yog qhov kev txiav txim siab - lawv sawv cev rau lub cev txwv ntawm cov khoom siv tuag nyob rau hauv kev thauj khoom cyclic. Ua txhaum lawv thiab koj them nyiaj hauv kev sib tsoo, kev tsim burr, lossis qhov sib txawv ntawm hnub Monday sawv ntxov tshaj hnub Friday yav tav su.

Tolerance Accumulation hla ntau qhov chaw nres tsheb

Ntawm no yog ib tug subtlety uas catches ntau engineers tawm tus neeg zov. Txhua qhov chaw nres tsheb hauv cov cuab yeej nce qib thiab tuag muaj nws tus kheej txoj haujlwm kam rau ua - feem ntau ± 0.01 txog ± 0.02mm rau qhov zoo- cov cuab yeej tsim. Suab nruj. Tab sis cov yuam kev me me no tsis nyob ib leeg. Lawv pawg.

Xav txog ib feem uas yuav tsum tau muaj lub qhov pierced nyob rau hauv chaw nres tsheb 3, ib tug tsim feature nyob rau hauv chaw nres tsheb 7, thiab ib tug zaum kawg txiav tawm nyob rau hauv chaw nres tsheb 12. Qhov positional kev sib raug zoo ntawm lub qhov thiab cov tsim feature qhia txog qhov cumulative yuam kev ntawm txhua strip advancement ntawm chaw nres tsheb 3 thiab 7. Yog hais tias lub sawb drifts 0.01mm ib pitch ntawm 0.0 ninety chaw nres tsheb. - txawm nrog ib tug zoo kawg nkaus ua tuag.

Qhov no yog vim li cas qhov kawg ntawm qhov kam rau ua yog ib txwm xoob dua li qhov chaw nres tsheb rau tus kheej. Kev tuag uas tuav ± 0.015mm ntawm txhua qhov chaw nres tsheb yuav xa ± 0.05mm ntawm qhov tiav rau cov yam ntxwv tsim ntawm cov chaw sib cais dav. Cov neeg tsim khoom suav txog qhov sib txawv no los ntawm kev sib faib cov yam ntxwv sib txawv rau hauv tib lub chaw nres tsheb lossis chaw nres tsheb uas nyob ib sab txhua qhov chaw. Nta nrog nruj kev sib nrig sib kam tau txais punched ib txhij - ib stroke, ib txoj hauj lwm siv, tsis cumulative drift.

Pilot Pin Strategy thiab Positional Accuracy Control

Pilot pins yog thawj qhov kev tiv thaiv tiv thaiv kev noj zaub mov yuam kev. Lawv rov- sau npe rau daim kab xev ntawm lub sijhawm raug, rov pib qhov kev sib tw ua ntej nws sib txuas dhau qhov kev txwv.

Lub tswv yim ua haujlwm zoo li no: cov qhov pilot yog xuas nrig ntaus ntawm thawj qhov chaw nres tsheb thiab muab tso rau ntawm cov cab kuj uas lawv yuav tsis cuam tshuam nrog ib feem nta. Pib ntawm qhov chaw nres tsheb thib ob, tus tsav pins nqis los rau hauv cov qhov ua ntej kev txiav los yog kev tsim tshwm sim, rub lub sawb mus rau hauv txoj hauj lwm. Tus pin-rau- qhov haum yog feem ntau 0.005-0.01mm clearance - nruj txaus los kho drift, xoob txaus kom tsis txhob tawg lub qhov.

Qhov sib txawv tseem ceeb. Kev teeb tsa tus pins tsav tsheb txhua ob mus rau peb qhov chaw nres tsheb tiv thaiv kev ua yuam kev los ntawm kev sib sau ntau dhau kev tswj hwm. Rau qhov siab - qhov tseeb, cov kws tsav dav hlau ntawm txhua qhov chaw nres tsheb muab cov ntawv sau npe nruj tshaj plaws. Thaum ob pawg tsav tsheb yuav tsum tau, xuas nrig ntaus ob leeg ib txhij ua kom lawv muaj kev sib nrig sib raug zoo es tsis qhia lawv tus kheej txoj hauj lwm offset.

Sawb kev taw qhia complements piloting. Cov ntaub ntawv qhia khaws cia cov kab nrib pleb nyob rau sab nraud thaum pub mis, thaum cov lifters tswj kev nce siab ntawm cov chaw nres tsheb. Ua ke, cov ntsiab lus no tsim ib txoj hauv kev uas tswj cov khoom ntws hauv tag nrho peb axes - lateral, longitudinal, thiab ntsug. Yog tias tsis muaj kev tswj hwm kev sib koom tes no, txawm tias tsim kom zoo kawg nkaus stamping tuag Cheebtsam tsis tuaj yeem xa rov ua dua uas siab - ntim ntau lawm xav tau.

DFM cov cai tswj tus kheej cov yam ntxwv tsim tau. Kev tswj kev kam rau siab ua kom tag nrho ib feem sib koom ua ke. Tab sis txawm tias nrog geometry thiab qhov chaw nyob rau hauv kev tswj, tus tsim tseem ntsib ib tug zaum kawg validation teeb meem: ua pov thawj los ntawm simulation thiab lub cev tryout hais tias tus tuag yuav ua tau raws li kev kwv yees nyob rau hauv cov xovxwm tiag tiag.

CAD thiab CAE Simulation hauv Modern Progressive Die Engineering

Ua pov thawj tus qauv tsim ntawm kev tshuaj ntsuam ua ntej txiav steel suab pom tseeb, tab sis nws tau hloov pauv hloov zuj zus mus txog lub khw hauv pem teb. Ib xyoo caum dhau los, validating ib tug complex strip layout txhais tau tias tsim lub cuab tam thiab khiav mus sib hais qhov chaw - ib tug kim tswv yim voj qhov twg txhua kho yuav tsum tau lub cev re-machining. Niaj hnub no, kev txhim kho tuag tsim software ua ke nrog CAE simulation cia cov engineers iterate digitally, tsoo dab tsi ib zaug siv lub lis piam ntawm kev sim rau hnub ntawm kev suav.

FEA Forming Analysis thiab Caij Nplooj Ntoos Hlav -Kev Ua Phem Rov Qab

Finite element tsom xam ua qauv dab tsi tshwm sim rau cov hlau ntawm txhua qhov chaw nres tsheb hauv granular nthuav dav. Lub software meshes lub sawb geometry, siv cov khoom siv, thiab simulates cov txheej txheem ua ntu zus raws li kev sib cuag tiag tiag, kev sib txhuam, thiab cov khoom ntim khoob. Txhua qhov kev tawm dag zog yog rov ua dua zoo li - punches nqis, cov khoom deforms, thiab tus neeg daws teeb meem suav kev faib tawm kev ntxhov siab, thinning, thiab strain tawm tsam daim duab txwv.

Caij nplooj ntoos hlav- rov qab kwv yees zaum ntawm qhov tseem ceeb ntawm qhov kev tshuaj ntsuam no. Raws liKeysight's engineering team sau tseg, physics raug-raws li cov neeg daws teeb meem taug qab cov kev ntxhov siab hauv zos thoob plaws hauv cov txheej txheem tsim, xa cov txiaj ntsig rov qab los ntawm cov qauv hlau los ntawm qib siab - lub zog zoo li DP800 thiab siab dua. Lub simulation ces pub cov cuab yeej them nyiaj rov qab rau hauv CAD qauv - kho lub ntsej muag tuag kom qhov chaw so rau hauv qhov tshwj xeeb es tsis txhob tawm ntawm nws.

Nov yog cov kev simulation tseem ceeb uas tau ua thaum lub sij hawm ua tiav kev tuag engineering thiab txhua qhov kev siv tau li cas:

• Formability tsom xam- Txiav txim siab cov kab nrib pleb, sib cais, thiab ntau dhau los ntawm daim ntawv qhia kev sib tw tiv thaiv cov khoom tsim kev txwv nkhaus.

Virtual Press Simulation thiab Design Iteration

Niaj hnub nimno platforms mus dhau qhov kev soj ntsuam zoo li qub. Cov cuab yeej zoo li Logopress ProgSim muaj nuj nqi raws li kev ua haujlwm zoo tshaj plaws ntawm cov xovxwm stamping, khiav cov kev sib txuas ua ke ntawm txhua qhov chaw nyob hauv ib ntus. Lub software cia li paub txog kev txiav thiab tsim cov punches los ntawm cov kab nrib pleb, kho lub siab -pad quab yuam thaum nws pom wrinkling, thiab tshaj tawm ob qho tib si pad quab yuam thiab tsim tonnage rau txhua qhov chaw nres tsheb. Cov kws ua haujlwm saib lub voj voog xovxwm virtual ze ze los ntawm kev nce ntxiv, txheeb xyuas cov teeb meem uas tsuas yog tshwm sim thaum ntau lub chaw nres tsheb sib cuam tshuam - strip distortion tom qab daim ntawv sib sib zog nqus, pub tsis ruaj khov los ntawm asymmetric rog, lossis cov cab kuj thinning uas tsis muaj zog strip thauj ntawm cov chaw nres tsheb.

Lub voj voj voog no nrawm nrawm. Kev simulation me me tuaj yeem ua tiav hauv feeb; qhov loj dua, ntau- chaw nres tsheb cuab yeej hauv ob peb teev. Muab piv rau lub voj voog ib txwm muaj ntawm machining kho, rov- sib dhos, thiab rov sim dua - qhov twg txhua qhov kev siv lub cev tuaj yeem noj hnub thiab ntau txhiab nyiaj hauv lub sijhawm tshuab. Platforms zoo li Altair Inspire Form ntxiv qhov muaj peev xwm ua tau los txheeb xyuas qhov chaw hauv vib nas this, muab cov neeg tsim qauv tawm tswv yim tam sim ntawd thaum ntxov lub tswv yim txhim kho ua ntej tag nrho cov tshuab stamping simulation khiav.

Yuav ua li cas Simulation txo qhov kev sim ua voj voog thiab tus nqi

Lub payoff yog ntsuas. Raws likev lag luam engineering cov ntaub ntawv, cov tuam txhab siv CAE-tsav tuag tsim feem ntau txo qhov kev sim ntawm lub cev los ntawm 30-50%. Qhov kev txo qis ncaj qha compresses lub sij hawm txhuas, txiav cov cuab yeej hloov kho tus nqi (tsawg dua vuam, sib tsoo, thiab rov ua dua-machining), thiab ua kom lub sijhawm- mus rau kev lag luam rau qhov tshiab.

Cov ntaub ntawv simulation tseem pub rau pem hauv ntej rau kev tsim khoom. Cov qauv ntxaib ntawm cov tuag - calibrated tiv thaiv kev ntsuas ntsuas - tso cai rau cov kws tsim khoom siv los kwv yees seb lub cuab yeej yuav coj li cas thaum hnav khaub ncaws ntau lossis cov khoom hloov pauv ntau. Thaum cov khoom coil tuaj yeem txav los ntawm nominal, cov qauv simulation chij cov chaw nres tsheb twg muaj kev nkag siab zoo tshaj plaws thiab cov txheej txheem hloov kho dab tsi tuaj yeem them rov qab yam tsis muaj re- txiav cov cuab yeej. Qhov kev kwv yees muaj peev xwm hloov pauv qhov simulation los ntawm ib qho - lub sij hawm tsim cov cuab yeej siv tau rau hauv cov cuab yeej tsim kho kom zoo dua qub.

Lub zog ntws ntws los ib yam nkaus. Simulation cov txiaj ntsig niaj hnub ua rau cov neeg tsim qauv rov txhim kho qhov chaw nres tsheb, faib ib qho kev pheej hmoo -theem daim ntawv mus rau ob theem maj mam, lossis hloov ntawm ib qib khoom mus rau lwm qhov uas ua rau muaj kev kwv yees ntau dua ntawm qhov xav tau geometry. Nyob rau hauv txoj kev no, kev txhim kho tuag tsim software tsis tsuas yog lees paub qhov kev txiav txim siab - nws nquag hloov kho lawv, ntes kim yuam kev ntev ua ntej lawv mus txog hauv pem teb xovxwm.

Tseem, simulation tsis tuaj yeem tiv thaiv txhua qhov teeb meem. Qee hom kev ua tsis tiav - slug rub, punch qaug zog, misfeed- cuam tshuam txog kev sib tsoo - tshwm sim los ntawm kev sib cuam tshuam ntawm kev tsim tuag, xovxwm dynamics, thiab cov xwm txheej ntau lawm uas txawm tias qhov zoo tshaj plaws virtual qauv kwv yees es tsis rov ua dua. Nkag siab txog cov txheej txheem tsis ua haujlwm ntawm qib tsim qauv yog txheej tom ntej ntawm kev tiv thaiv.

Tiv Thaiv Kev Ua Phem Tuag Ua Tsis Tau Los Ntawm Kev Tsim Ntse

Simulation catches tsim qhov tsis xws luag ua ntej sim. Tab sis cov hlau stamping tuag tuaj yeem dhau txhua qhov kev lees paub virtual thiab tseem tsim teeb meem kev tsim khoom ntev - slug rub uas cuam tshuam cov cuab yeej, xuas nrig ntaus tom qab 50,000 hits, burrs loj hlob kom txog thaum cov khoom tsis raug tshuaj xyuas. Cov kev ua tsis tiav no tsis tshua tshwm sim tam sim ntawd. Lawv tsim maj mam dhau los ntawm kev hnav khaub ncaws, strip instability, thiab lubrication inconsistency thaum lub sij hawm mus tas li. Qhov kev pom tseem ceeb? Lawv feem ntau taug qab mus rau qhov kev txiav txim siab tau ua - lossis plam - thaum lub sijhawm tsim tuag.

Hom Kev Ua Tsis Taus Feem Ntau thiab Lawv Tsim -Qib Cov Hauv Paus

Thaum qhov kev tuag zuj zus pib tsim qhov tsis zoo, feem ntau koj yuav pom ib qho ntawm tsib cov tsos mob ua ntej. Txhua lub ntsiab lus rau kev tsim qauv sib txawv -qib qhov tsis zoo:

Daim ntawv ceeb toom yuav ua li cas cov kev ua tsis tiav no sib cuam tshuam. Punch hnav nce burr qhov siab. Loj hlob burrs tsa stripping kuj. Ntau dua stripping quab yuam ua rau slugs mus rau ntawm lub ntsej muag lub ntsej muag thaum tshem tawm, ua rau slug rub. Ib qho kev txiav txim siab tsim qauv tsis pom zoo cuam tshuam los ntawm cov kab ke - uas yog vim li cas cov neeg tsim qauv paub txog kev tiv thaiv tsis ua haujlwm raws li kev tawm dag zog holistic es tsis hais txog txhua hom kev sib cais.

Force xam thiab nias Tonnage kwv yees

Suab complex? Cov mis rau blanking thiab piercing tonnage nyob rau hauv ib tug tuag stamping xovxwm yog qhov tseeb ncaj nraim. Rau txhua qhov kev ua haujlwm txiav, qhov xav tau quab yuam sib npaug ntawmperimeter ntawm qhov txiav multiplied los ntawm cov khoom thickness multiplied los ntawm cov khoom shear zog. Rau kev kos duab, hloov lub zog tensile kawg vim lub plhaub phab ntsa yog nyob rau hauv nro thaum tsim.

Hauv kev tuag zuj zus, koj yuav tsum suav cov khoom thauj thoob plaws txhua qhov chaw nres tsheb ua haujlwm ib txhij thaum ib zaug nias. Qhov no suav nrog:

• Txhua qhov tho thiab qhov chaw nres tsheb (perimeter x thickness x shear zog)
• Kev tsim, khoov, thiab kos duab chaw nres tsheb (xws li ib hom kev ua haujlwm)
• Caij nplooj ntoos hlav stripper siab tuav lub strip tiaj tus
• Lifter pin quab yuam tsa lub strip ntawm strokes
• Nitrogen ncoo quab yuam rau siab- nyob ntawm kev ua haujlwm
• Qhwv cutter loads ntawm qhov chaw nres tsheb zaum kawg

Ntxiv cov no ua ke thiab koj tau txais tag nrho cov tuag tonnage. Tab sis nias xaiv tsis nres ntawd. Koj yuav tsum tau suav cov kev xav tau ntawm lub zog - vim tias lub xovxwm tuaj yeem muaj peev xwm tonnage txaus tab sis tsis muaj lub zog los ua kom tiav cov hlab ntsha. Lub zog tsis txaus yog ib qho ua rau cov xovxwm kaw nyob rau hauv qab qhov chaw tuag, tshwj xeeb tshaj yog nyob rau hauv kev kub ceev kev loj hlob tuag stamping qhov twg ceev cycling depletes flywheel zog sai dua lub cev muaj zog replenishes nws.

Ib txoj cai muaj txiaj ntsig: qhov loj ntawm cov xovxwm ntawm 60-70% ntawm nws cov peev txheej ntsuas rau kev suav tuag. Khiav ib lub xovxwm ntawm los yog ze rau tag nrho tonnage accelerates ncej deflection, bearing coj, thiab qhia kev degradation. Ib qho kev tuag stamping xovxwm tsis yog tsuas yog pheej hmoo jamming - nws shortens tuag lub neej los ntawm kev qhia deflection-induced misalignment uas sib xyaw nrog txhua tus mob stroke.

Kev tiv thaiv tsim cov tswv yim rau lub neej ntev

Stamping tuag tu cov nqi poob qis heev thaum tuag yog tsim los nrog lub neej ntev raws li qhov tseem ceeb tshaj li qhov kev xav tom qab. Cov tswv yim zoo tshaj plaws hais txog hnav ua ntej nws pib:

• Stagger punch qhov siab- Stepping txiav punches ntawm 0.5-1.0x cov khoom thickness offsets lub sij hawm kom tsis txhob tag nrho cov chaw nres ib txhij. Qhov no txo ​​cov tonnage ncov los ntawm 30-40% thiab txo qis kev poob siab ntawm cov xovxwm.
• Siv cov carbide ntxig rau hauv siab -cov cheeb tsam hnav- Cov chaw nres tsheb ciav hlau khiav cov hlau tsis muaj steel lossis siab - lub zog alloys tau txais txiaj ntsig los ntawm kev hloov pauv carbide inserts uas tswj kev ncaj ncees ntawm ntau lab lub voj voog.
• Tsim rau kev hloov modular- Tsim cov seem tuag raws li kev ywj pheej ntxig thaiv es tsis yog cov phiaj xwm monolithic. Thaum hnav concentrates ntawm ib qho chaw nres tsheb tshwj xeeb, koj muab kev pab cuam uas tsis tau disassembling tag nrho cov cuab yeej.
• Qhia meej txog kev kho kom zoo- TiN, TiAlN, lossis DLC txheej ntawm cov punches txo kev sib txhuam, txo qis kev pheej hmoo, thiab txuas ntxiv lub sijhawm sib tw. Muab cov txheej rau cov khoom siv ua haujlwm kom tau txais txiaj ntsig zoo tshaj plaws.
• Muab cov khib nyiab khiav tawm- Tsim slug txoj kev khiav tawm nrog cov duab dav dav dav dav thiab huab cua- tshuab raj. Thaum muaj kev kub ceev, slugs uas khiav tawm kom huv ntawm 200 SPM tuaj yeem pib rov qab los ntawm 400 SPM yam tsis muaj kev xa xov zoo.
• Sib npaug sib sau loads hla lub strip dav- Asymmetric rog twist lub strip thiab sab -load qhia tshuab. Nyob qhov twg symmetry tsis yog geometrically ua tau, counterbalance nrog strategically muab tso tseg chaw nres tsheb los yog opposing daim ntawv nta.

Cov no tsis yog kev kho tom qab muag. Lawv yog cov qauv tsim- theem kev txiav txim siab - ua rau hauv CAD qauv, muaj tseeb hauv kev simulation, thiab ua pov thawj thaum sim. Kev nce qib stamping tuag tsim los rau kev tiv thaiv kev nkag mus thiab kev sib npaug ntawm lub zog sib npaug yuav ua haujlwm ntev dua ntawm qhov kev pabcuam, tsim cov khoom sib xws, thiab raug nqi tsawg dua ib lab strokes dua li lub cuab yeej uas lub neej ntev yog qhov kev xav tom qab.

Kev tiv thaiv tsis ua haujlwm thiab kev tswj hwm kev tiv thaiv kev tuag nws tus kheej. Tab sis kev tuag uas khiav zoo technically tseem tuaj yeem ua tsis tau nyiaj txiag - siv peev nyiaj ntau dhau ntawm qhov nws rov qab los. Kev nkag siab txog tus nqi tsav tsheb thiab kev lag luam kev lag luam tom qab cov phiaj xwm tuag tau zoo cais cov engineering zoo los ntawm kev txiav txim siab ua lag luam zoo.

Tus nqi tsav tsheb thiab kev lag luam ntawm Progressive Die Projects

Ib tug tuag uas ua tsis tau zoo tseem xav tau kev nkag siab txog nyiaj txiag.
