OEM hlau dabtsi yog khoov, Punching, Thiab Stamping Tuag; Automotive Parts Stamping Tuag

I. Kev xaiv cov khoom siv rau Ultra-Long Service Dies
Ultra-ntev kev pab cuam lub neej stamping tuag nyiam siv siab- lub zog, siab- tawv, thiab hnav- cov hlau tsis muaj zog. Cov qib tseem ceeb yog H13, SKD11, thiab DC53. H13 steel muaj molybdenum, vanadium, thiab chromium alloying cov ntsiab lus, thiab nws qhov hardness tom qab quenching tuaj yeem ncav cuag HRC58-62, ua rau nws haum rau nruab nrab - mus rau - siab zog stamping daim ntawv thov. SKD11 steel muaj cov ntsiab lus chromium siab, ua kom pom kev hnav zoo heev, ua rau nws tsim nyog rau kev txiav txim siab tuag.

Hmoov metallurgy tuag steels (xws li CPM 10V thiab ASP 23) yog tsim los siv cov txheej txheem hmoov metallurgy. Lawv muaj cov qauv microstructure zoo, cov nplej zoo, thiab tsis muaj kev sib cais tseem ceeb. Lawv cov tawv tawv thiab hnav tsis kam yog qhov zoo tshaj rau cov hlau forged tuag, txuas lawv lub neej kev pab cuam los ntawm 3-5 zaug piv rau cov hlau tuag zoo tib yam. Lawv feem ntau yog siv rau hauv kev tsim khoom ntawm ultra- ntev kev pab cuam lub neej tuag rau siab - stamping ceev thiab stamping ntawm complex-puab qhov chaw.

II. Txoj kev kho cua sov tshiab rau Ultra-Long Life Pwm

Cov txheej txheem ntau-theem quenching yog ua haujlwm. H13 steel yog rhuab mus rau 1050-1080℃thiab tuav rau 2-3 teev, tom qab ntawd cua txias rau 600 degree, ua raws li cov roj txias kom qis dua 150℃los tiv thaiv pwm tawg. Kev ntsuas kub qis yog ua ntawm 180-220℃rau 4-6 teev kom tshem tawm kev ntxhov siab, ntsuas pwm hardness thiab toughness, thiab tiv thaiv chipping thaum siv.

Cov txheej txheem nqus cua sov ua kom tiav hloov cov tshuaj ntsev da dej quenching. Lub tshuab nqus tsev yog tswj tau qis dua 10⁻³ Pa, qhov cua sov yog 5-10℃/ min, thiab cov pa roj cua txias yog siv los tiv thaiv pwm nto oxidation thiab decarburization, txhim kho deg hardness uniformity, thiab txo qhov tsis xws luag.

Kev txhim kho saum npoo siv cov txheej txheem roj nitriding lossis ion nitriding, nrog rau qhov kub ntawm nitriding ntawm 500-550℃thiab tuav lub sijhawm 8-12 teev. Cov txheej txheej nitrided yog tswj ntawm 0.15-0.3mm, ua tiav qhov tawv tawv ntawm HV800 lossis siab dua, txhim kho qhov hnav tsis kam thiab qaug zog ntawm cov pwm txiav npoo. Rau cov pwm nyuaj, cov txheej txheem carbonitriding yog siv, ntsuas qhov tawv tawv thiab txheej tawv tawv, txuas ntxiv pwm lub neej kev pabcuam.

III. Digital thiab txawj ntse optimization ntawm cov txheej txheem kho cua sov

Siv cov kev kho cua sov simulation software (xws li Deform thiab Sysweld), cov khoom pwm muaj pes tsawg leeg thiab qhov ntsuas qhov ntev yog cov tswv yim los simulate qhov kub thiab txias thaum lub sij hawm cua sov thiab txias. Qhov no optimizes tsis xws li quenching kub, tuav lub sij hawm, thiab txias npaum li cas, tsis txhob sim - thiab - nqi yuam kev thiab xyuas kom meej pwm kev ua tau zoo.

Cov cuab yeej siv kho cua sov yog txuas nrog lub tshuab ntsuas ntse, uas sau cov ntaub ntawv xws li cua sov, cua sov cua sov, thiab cua txias hauv lub sijhawm. Los ntawm kev txheeb xyuas cov ntaub ntawv loj, cov txheej txheem tsis raug hloov kho kom ua tiav cov kev kho cua sov zoo sib xws thoob plaws ntau pawg pwm, ua kom lub voj voog pwm tsim thiab txo qhov tsis xws luag.

IV. Ntsuab thiab Zog -Txuag Optimization ntawm cov txheej txheem kho cua sov

Lub zog- txuag thiab ib puag ncig tus phooj ywg lub tshuab nqus tsev kho cua sov tau txais yuav, nruab nrog lub tshuab hluav taws xob pov tseg. Kev siv hluav taws xob tau nce los ntawm 25% -30% piv rau cov tsoos quenching rauv, txo cov pa khib nyiab thiab dej khib nyiab thiab ua kom tau raws li kev tiv thaiv ib puag ncig.

Los ntawm cov khoom siv optimization thiab txhim kho cov txheej txheem kev kho cua sov, kev pab cuam lub neej ntawm pwm yog nce los ntawm cov pa 100,000-300,000 mus rau 500,000-1,000,000 cycles, txo pwm hloov zaus, txo pwm cov khoom noj, thiab ua tiav kev txuag.
