Vim li cas cov tooj liab ntshiab, cov khoom siv raw rau Copper Stamping Parts, hu ua ntshav tooj liab?

Ntshiab tooj liab yog hu ua liab doog tooj liab feem ntau vim yog xim ntawm nws nto oxide zaj duab xis. Thaum muaj cov ntshiab tooj liab raug rau cov huab cua, ib tug ntom oxide zaj duab xis ib txwm ua rau nws nto. Cov yeeb yaj kiab no nthuav tawm "reddish-liab" xim, es tsis yog xim liab ntawm violet. Nws yog cov yeeb yaj kiab liab oxide uas muab cov tooj liab ntshiab nws lub npe, "ntsuab tooj liab," tus cwj pwm kom pom tseeb los ntawm kev cai tooj liab stamping tuam txhab thaum ua.

Dhau li ntawm nws lub npe, cov qauv siv lead ua thiab microstructure ntawm cov tooj liab ntshiab kuj txiav txim siab nws txoj haujlwm tseem ceeb hauv kev lag luam tooj liab stamping. Ntshiab tooj liab tuav lub ntsej muag -centered cubic (FCC) siv lead ua qauv ntawm ob qhov kub thiab txias. Cov qauv siv lead ua no ua rau nws zoo heev hluav taws xob thiab thermal conductivity, deb tshaj li ntawm tooj dag, bronze, thiab lwm yam tooj liab alloys. Qhov no yog qhov laj thawj tseem ceeb vim li cas tooj liab ntshiab yog siv dav hauv cov khoom siv hluav taws xob tooj liab stamping. Cov hluav taws xob conductivity ntawm daim ntawv tooj liab stamping ncaj qha nyob ntawm cov khoom siv ntawm cov tooj liab ntshiab.

Los ntawm kev pom microscopic, raws li - nrum tooj liab muaj - theem qauv. Thaum muaj cov kab mob tshwm sim, nws tsim - cov kev daws teeb meem los yog thib ob - cov kab ke thiab cov khoom sib txuas, thiab hauv cov xwm txheej hnyav, cov pob zeb dendritic me ntsis tuaj yeem tshwm sim. Tom qab ua tiav thiab deformation, cov qauv ntawm tooj liab hloov raws li, tsim cov qauv deformed. Cov yam ntxwv ntawm cov qauv no ua rau nws haum rau ntau yam txheej txheem tooj liab stamping. Lub precision tsim ntawm Hluav taws xob tooj liab Stamping Parts cia siab rau qhov zoo heev structural stability ntawm tooj liab.

Copper muaj kev ua tau zoo heev, uas yog qhov laj thawj tseem ceeb vim li cas nws yog cov khoom siv raw rau tooj liab stamping. Hauv kev tsim khoom, tooj liab yuav luag tag nrho raws li cov khoom lag luam tiav. Nws cov yas zoo heev tso cai rau kev ua tiav txog li 99%, ua kom muaj ntau yam txheej txheem stamping kom tiav yam tsis muaj qhov nruab nrab annealing, txhim kho qhov ua tau zoo ntawm tooj liab stamping. Kev tsim khoom loj ntawm Hlau Stamping Parts Electric Copper cia siab rau kev ua haujlwm zoo ntawm tooj liab.

Tooj liab muaj qhov kub tsis tshua muaj recrystallization, tsuas yog 200-280 degree. Cov yam ntxwv no tso cai rau kev hloov pauv ntawm cov khoom siv los ntawm cov txheej txheem annealing thaum lub sij hawm tooj liab stamping. Thaum qee cov ntsiab lus alloying ntxiv, qhov kub ntawm cov tooj liab recrystallization nce los yog txo. Nrog rau qhov kub thiab txias thiab lub sij hawm, cov nplej recrystallized loj hlob, cuam tshuam rau hardness thiab ductility ntawm tooj liab. Kev tswj kev ua haujlwm ntawm tooj liab stamping qhov chaw feem ntau nyob ntawm tus yam ntxwv annealing no.

Feem ntau tshwm sim nyob rau hauv lub annealed microstructure ntawm tooj liab yog annealing ntxaib, ib tug yam ntxwv ntawm tooj liab lub microstructure. Nyob rau hauv lub ntsej muag -centered cubic crystal ntawm tooj liab, atoms yog teem nyob rau hauv ib tug nyob ze-packed yam ntawm lub (111) siv lead ua dav hlau, thaum annealing ntxaib yog tsim los ntawm atoms teem symmetrically txog ib tug tej yam siv lead ua dav hlau. Qhov no microstructure ntxiv txhim khu cov ductility thiab toughness ntawm tooj liab, ua tau raws li qhov yuav tsum tau ntawm siab - precision stamping txheej txheem xws li tooj liab stamping.
