Yuav ua li cas tsawg lossis siab st13 steel phaj muaj kev cuam tshuam stamping?
Ob qho tib si loj thiab qis st13 steel phaj hardness tuaj yeem cuam tshuam ntau stamping kev ua tau zoo, feem ntau nyob rau hauv kev tsim kev ua si, pwm hnav, thiab khoom lag luam zoo:
1. Kev cuam tshuam ntawm kev tawv tawv
Kev nyuaj ua nyuaj: Hardness Ntau dua txhais tau tias cov khoom siv yas ua kom muaj zog, xav tau ntau dua kev ua kom tiav cov yas txawv txav thaum stamping. Qhov chaw nrog cov duab nyuaj (xws li kev sib sib zog nqus thiab ntau txoj kev sib sib zog nqus) yog tau mus rau kev tawg ua kom muaj kev ntxhov siab, ua rau tawg, wrinkling, lossis khawb. Cov kev tsis xws luag yog nquag nquag yuav tsim kho cov ces kaum ntse thiab sib sib zog nqus kab noj hniav.
Nce pwm ua kom loj hlob: cov khoom siv tawv tawv loj nce kev sib txhuam thiab ua rau muaj cov pwm, ua rau cov pwm ua tau zoo nkauj, ua rau cov khoom lag luam ntau dhau, cuam tshuam rau qhov precisent ntawm cov khoom lag luam txuas ntxiv. Cov Khoom Siv Tseem Ceeb: Cov ntaub ntawv muaj ntau dua hardness kev ntau tshaj tawm elastic rov qab (springback) tom qab stampings nyob rau hauv ib feem qhov tseeb raug. Tshwj xeeb, cov ces kaum thiab nkhaus ntawm cov khoom bent tuaj yeem yooj yim tshaj cov qauv tsim qauv (xws li ntxiv kho cov kauj ruam txhim kho) kom them nyiaj.
2. Kev cuam tshuam ntawm kev tawv tawv qis
Cov khoom siv tsis txaus: Tsawg zog yuav ua tau los ntawm cov khoom muaj ntau dhau lub zog, ua cov khoom siv rau kev tawm tsam ntau lossis "poob siab" thaum lub sijhawm sib tsoo. Qhov no muaj tseeb tshwj xeeb thaum lub sij hawm ncab, qhov twg tsis muaj teeb meem ntawm cov npoo ntawm cov av uas tsis muaj qab hau, lossis thinning ntau dhau los yuav ua rau scrapping ntawm workpiece.
Cov teeb meem zoo: Cov ntaub ntawv muaj zog tsawg dhau yog nquag mus rau ntawm cov khoom sib txhuam, lossis cov khoom siv hauv zos vim muaj cov khoom muaj zog dhau los, cuam tshuam rau cov khoom lag luam zoo.
Cov khoom tsis muaj zog ruaj khov: Vim tias cov khoom siv tsis txaus ntseeg, ua rau muaj kev deformes thib ob (xws li welding Ntsiab lus: ST13, raws li ib tug tshwj xeeb stamping steel, yog tsim nrog kev nyuaj tshwj xeeb nyob rau hauv cov qib siab ntawm 50-70 hrb kom ua tiav qhov sib npaug ntawm kev sib npaug thiab lub zog. Hardness uas yog dhau los yog dhau qhov kev cuam tshuam dhau los lossis qis dhau qhov kev sib npaug no, nce kev ua nyuaj thiab cov nqi sib tw. Yog li ntawd, hauv kev tsim tiag tiag, lub hardness yuav tsum tau nruj me ntsis tswj nyob rau hauv tus qauv txheem kom ntseeg tau ruaj khov nyob hauv cov txheej txheem stamping thiab khoom zoo.
