Ntawm cov khoom hlau hauv ntiaj teb, 60-70% yog daim hlau, feem ntau yog stamped rau hauv cov khoom tiav. Lub cev, chassis, roj tank, radiator fins ntawm lub tsheb, lub nruas ntawm lub boiler, lub plhaub ntawm lub thawv, cov hlau tub ntxhais silicon steel ntawv ntawm lub cev muaj zog, thiab cov khoom siv hluav taws xob yog tag nrho stamped. Kuj tseem muaj ntau qhov chaw stamping nyob rau hauv cov khoom xws li cov twj paj nruag thiab ntsuas, cov khoom siv hauv tsev, tsheb kauj vab, cov tshuab ua haujlwm, thiab cov khoom siv nyob.
Piv nrog rau castings thiab forgings, stamping qhov chaw muaj cov yam ntxwv ntawm thinness, uniformity, lightness thiab lub zog. Stamping tuaj yeem tsim cov khoom ua haujlwm nrog cov tav, tav, undulations lossis flanges uas nyuaj rau kev tsim khoom los ntawm lwm txoj hauv kev los ua kom lawv cov rigidity. Vim yog kev siv cov pwm precision, qhov precision ntawm lub workpiece tuaj yeem ncav cuag micron theem, thiab qhov rov ua dua yog siab, thiab cov lus qhia tshwj xeeb zoo ib yam, thiab qhov, cov thawj coj, thiab lwm yam tuaj yeem raug punched.
Txias stampings feem ntau tsis txiav, lossis tsuas yog yuav tsum tau txiav me me xwb. Qhov tseeb thiab qhov chaw ntawm qhov kub stamping qhov chaw yog qis dua qhov txias stamping qhov chaw, tab sis tseem zoo dua li castings thiab forgings, thiab txiav nyiaj tsawg dua.
Stamping yog ib txoj kev ua tau zoo. Siv cov khoom sib xyaw, tshwj xeeb tshaj yog cov chaw nres tsheb loj zuj zus, tuaj yeem ua tiav ntau yam txheej txheem stamping ntawm ib lub xovxwm, paub txog tag nrho cov txheej txheem los ntawm strip uncoiling, leveling, xuas nrig ntaus los ua thiab xov. tsis siv neeg ntau lawm. Kev ua haujlwm ntau lawm yog siab, kev ua haujlwm zoo, thiab cov nqi tsim khoom tsawg. Feem ntau, ntau pua daim tuaj yeem tsim tau ib feeb.
Stamping feem ntau yog cais raws li cov txheej txheem, uas tuaj yeem muab faib ua ob pawg: txheej txheem sib cais thiab txheej txheem tsim. Cov txheej txheem kev sib cais kuj tseem hu ua xuas nrig ntaus, thiab nws lub hom phiaj yog cais cov stamping qhov chaw los ntawm cov ntaub ntawv raws li ib qho contour kab, thaum ua kom ntseeg tau qhov kev xav tau ntawm kev sib cais. Qhov saum npoo thiab sab hauv ntawm cov ntawv stamping muaj qhov cuam tshuam zoo rau qhov zoo ntawm cov khoom stamping. Nws yuav tsum tau hais tias lub thickness ntawm cov khoom stamping yuav tsum yog thiab uniform; nto yog du, tsis muaj pob, tsis muaj caws pliav, tsis muaj khawb, tsis muaj kab nrib pleb, thiab lwm yam .; Kev taw qhia; siab uniform elongation; qis yield ratio; low ua hauj lwm hardening.
