Pwm yog cov txheej txheem txheej txheem ntawm kev lag luam tsheb.Ntau tshaj 90% ntawm cov khoom thiab cov khoom siv hauv tsheb yuav tsum tau tsim los ntawm pwm.Raws li Luo Baihui, tus kws tshaj lij pwm, kwv yees li 1,500 pwm yuav tsum tau siv los tsim lub tsheb zoo tib yam, ntawm ntau tshaj 1,000 stamping pwm yog siv.Hauv kev tsim cov qauv tshiab, 90% ntawm kev ua haujlwm yog nqa tawm nyob ib ncig ntawm kev hloov ntawm lub cev profile.Kwv yees li 60% ntawm tus nqi tsim kho ntawm cov qauv tshiab yog siv rau kev txhim kho lub cev thiab stamping txheej txheem thiab cov khoom siv.Kwv yees li 40% ntawm cov nqi tsim tsheb yog tus nqi ntawm lub cev stamping qhov chaw thiab sib dhos.
Nyob rau hauv txoj kev loj hlob ntawm lub tsheb pwm kev lag luam nyob rau hauv tsev thiab txawv teb chaws, pwm tshuab tau qhia cov nram qab no txoj kev loj hlob tiam sis.
1. Kev simulation ntawm cov txheej txheem stamping (CAE) yog qhov tseem ceeb dua
Nyob rau hauv xyoo tas los no, nrog kev loj hlob sai ntawm computer software thiab hardware, simulation technology (CAE) ntawm cov txheej txheem stamping yog ua lub luag haujlwm tseem ceeb zuj zus.Hauv cov tebchaws tsim xws li Tebchaws Meskas, Nyiv, thiab Lub Tebchaws Yelemees, CAE thev naus laus zis tau dhau los ua ib feem tsim nyog ntawm kev tsim pwm thiab kev tsim khoom.Nws yog dav siv los kwv yees ua qhov tsis xws luag, txhim kho cov txheej txheem stamping thiab pwm qauv, txhim kho kev ntseeg siab ntawm pwm tsim, thiab txo lub sij hawm sim pwm.Ntau lub tuam txhab tsheb pwm hauv tsev kuj tau ua tiav tseem ceeb hauv daim ntawv thov CAE thiab ua tiav cov txiaj ntsig zoo.Daim ntawv thov ntawm CAE thev naus laus zis tuaj yeem txuag tau tus nqi ntawm cov pwm sim thiab ua kom lub voj voog loj hlob ntawm cov pwm pwm, uas tau dhau los ua ib qho tseem ceeb los xyuas kom meej pwm zoo.CAE thev naus laus zis tau maj mam hloov pwm tsim los ntawm kev tsim qauv rau kev tsim qauv.
2. Txoj hauj lwm ntawm pwm 3D tsim yog sib sau ua ke
Kev tsim qauv peb sab ntawm cov pwm yog ib feem tseem ceeb ntawm cov tshuab pwm digital thiab lub hauv paus rau kev sib koom ua ke ntawm pwm tsim, tsim khoom thiab tshuaj xyuas.Cov tuam txhab xws li Toyota thiab General Motors ntawm Tebchaws Meskas tau paub txog cov qauv peb-seem ntawm cov pwm thiab ua tiav daim ntawv thov zoo.Qee txoj hauv kev tau txais hauv 3D pwm tsim txawv teb chaws yog tsim nyog ntawm peb siv.Ntxiv rau qhov ua tau zoo rau kev ua tiav ntawm kev tsim khoom sib xyaw ua ke, kev tsim qauv peb-seem ntawm cov pwm muaj lwm qhov zoo dua uas nws yooj yim rau kev cuam tshuam kev tshuaj xyuas thiab tuaj yeem ua qhov kev cuam tshuam kev cuam tshuam, uas daws qhov teeb meem ntawm ob sab qauv tsim.
Thib peb, cov tshuab pwm digital tau dhau los ua cov kev taw qhia tseem ceeb
Nyob rau hauv xyoo tas los no, kev loj hlob sai ntawm cov tshuab pwm digital yog ib txoj hauv kev zoo los daws ntau yam teeb meem uas tau ntsib hauv kev tsim tsheb pwm.Lub npe hu ua digital mold technology yog kev siv tshuab computer lossis computer-aided technology (CAX) hauv pwm tsim thiab tsim cov txheej txheem.Kev ua tiav ntawm kev ua tiav ntawm cov tuam txhab tsim tsheb hauv tsev thiab txawv teb chaws hauv kev siv tshuab computer-pab thev naus laus zis, digital automotive pwm thev naus laus zis feem ntau suav nrog cov hauv qab no: ① Tsim rau kev tsim khoom lag luam (DFM), uas yog, kev tsim khoom raug txiav txim siab thiab tshuaj xyuas thaum tsim kom muaj kev vam meej. ntawm tus txheej txheem.②Auxiliary technology rau pwm profile tsim, tsim ntse profile tsim technology.③CAE pab hauv kev tshuaj xyuas thiab kev tsim cov txheej txheem, kwv yees thiab daws cov teeb meem uas tshwm sim thiab tsim teeb meem.④ Hloov cov qauv tsim ob sab nrog peb-seem qauv qauv tsim.⑤ Cov txheej txheem tsim pwm txais CAPP, CAM thiab CAT thev naus laus zis.⑥ Raws li kev taw qhia ntawm cov thev naus laus zis thev naus laus zis, suav nrog thiab daws cov teeb meem uas tshwm sim hauv cov txheej txheem pwm sim thiab stamping ntau lawm.
Plaub, txoj kev loj hlob sai ntawm pwm ua automation
Advanced processing technology thiab khoom siv yog lub hauv paus tseem ceeb rau kev txhim kho cov khoom tsim tau thiab ua kom cov khoom zoo.Nws tsis yog qhov tsis yooj yim rau cov tuam txhab tsheb pwm siab tshaj plaws kom muaj CNC tshuab cuab yeej nrog ob lub rooj ua haujlwm, cov cuab yeej hloov pauv tsis siv neeg (ATC), cov tshuab hluav taws xob tswj kev ua haujlwm tsis siv neeg, thiab cov tshuab ua haujlwm hauv online.Kev tswj cov lej tau tsim los ntawm kev ua haujlwm yooj yim mus rau kev ua tiav ntawm qhov profile thiab cov qauv txheej txheem, los ntawm kev ua haujlwm nruab nrab thiab qis qis mus rau kev ua haujlwm siab, thiab kev tsim cov txheej txheem automation yog nrawm heev.
5. High-strength steel phaj stamping tshuab yog txoj kev txhim kho yav tom ntej
High-strength steel muaj cov yam ntxwv zoo nyob rau hauv cov nqe lus ntawm yield ratio, strain hardening yam ntxwv, strain tis muaj peev xwm, thiab kev sib tsoo lub zog nqus, thiab tus nqi ntawm kev siv nyob rau hauv lub tsheb tseem nce.Tam sim no, cov hlau uas muaj zog siab siv hauv tsheb stampings feem ntau suav nrog cov xim tawv tawv hlau (BH steel), dual-theem steel (DP steel), thiab theem hloov pauv induced plasticity steel (TRIP steel).Lub International Ultra Light Body Project (ULSAB) kwv yees tias 97% ntawm lub tswv yim siab tshaj tsheb (ULSAB-AVC) tau tsim tawm xyoo 2010 yuav yog cov hlau muaj zog.Qhov kev faib ua feem ntawm cov qib siab zog steel hauv cov khoom siv hauv tsheb yuav ntau dua 60%, thiab ob theem Kev faib ua feem ntawm cov hlau yuav suav txog 74% ntawm cov tsheb hlau phaj.Cov hlau muag muag feem ntau siv hauv IF steel yuav yog high-strength steel phaj series, thiab high-strength low-alloy steel yuav yog dual-theem steel thiab ultra-high-strength steel phaj.Tam sim no, daim ntawv thov ntawm lub zog siab steel phaj rau cov khoom siv hauv tsev feem ntau txwv rau cov khoom siv thiab cov kab teeb, thiab lub zog tensile ntawm cov ntaub ntawv siv feem ntau yog qis dua 500MPa.Yog li ntawd, sai sai mastering lub stamping tshuab ntawm high-strength steel daim hlau yog ib qho teeb meem tseem ceeb uas yuav tsum tau daws sai sai nyob rau hauv kuv lub teb chaws lub tsheb pwm kev lag luam.
6. Cov khoom pwm tshiab yuav raug tsim tawm hauv lub sijhawm
Nrog rau txoj kev loj hlob ntawm high efficiency thiab automation ntawm lub tsheb stamping ntau lawm, daim ntawv thov kev vam meej tuag nyob rau hauv zus tau tej cov tsheb stamping qhov chaw yuav ua tau ntau dua.Cov txheej txheem nyuaj stamping qhov chaw, tshwj xeeb tshaj yog qee qhov me me thiab nruab nrab qhov nyuaj stamping qhov chaw uas yuav tsum tau muaj ntau txheej ntawm xuas nrig ntaus tuag raws li cov txheej txheem ib txwm muaj, yog nce zuj zus los ntawm kev tuag.Progressive tuag yog ib yam ntawm high-tech pwm khoom, uas yog technically nyuaj, yuav tsum tau high manufacturing precision, thiab muaj ib tug ntev ntau lawm voj voog.Cov chaw nres tsheb ntau qhov kev vam meej tuag yuav yog ib qho ntawm cov khoom pwm tseem ceeb tshaj plaws hauv kuv lub tebchaws.
Xya, cov ntaub ntawv pwm thiab cov cuab yeej kho mob saum npoo yuav rov siv dua
Qhov zoo thiab kev ua haujlwm ntawm cov khoom pwm yog qhov tseem ceeb uas cuam tshuam rau pwm zoo, lub neej thiab tus nqi.Nyob rau hauv xyoo tas los no, ntxiv rau kev qhia txuas ntxiv ntawm ntau yam kev ua haujlwm siab thiab siab hnav ua haujlwm txias txias steels, nplaim hluav taws kub quenched txias ua haujlwm tuag steels, thiab hmoov metallurgy txias ua haujlwm tuag steels, nws tsim nyog siv cov ntaub ntawv cam khwb cia hlau loj. thiab nruab nrab stamping tuag txawv teb chaws.Kev txhawj xeeb txog txoj kev loj hlob.Nodular cam khwb cia hlau muaj zoo toughness thiab hnav tsis kam, nws vuam kev ua tau zoo, workability, nto hardening kev ua tau zoo kuj zoo, thiab tus nqi qis dua alloy cam khwb cia hlau, yog li nws yog siv ntau nyob rau hauv tsheb stamping tuag.
8. Kev tswj xyuas kev tshawb fawb thiab kev tshaj tawm yog kev txhim kho kev lag luam pwm
