Vim li cas hlau stamping qhov chaw ua rau tawg?

Feem ntau tearing thiab skewing cov ntaub ntawv ntawm hlau stamping qhov chaw. Cov txheej txheem stamping ntawm nruab nrab tiv thaiv nto bracket yog: blanking thiab punching-punching incision-flanging forming-incision-flanging. Muaj ntau cov ntaub ntawv ntawm tearing thiab skew thaum lub sij hawm tsim cov txheej txheem ntawm nruab nrab tiv thaiv nto bracket. Cov khoom tsim kua muag feem ntau yog muab faib rau ntawm lub qhov qauv ntawm lub workpiece, thiab R arc ntawm lub ces kaum ntawm sab phab ntsa thiab qhov sib txuas ntawm lub caj dab ntawm phab ntsa, thiab lwm yam, vim yog stamping thiab ntau lawm qhov sib txawv ntawm cov txheej txheem, qhov kev faib ua feem ntawm txhua qhov tawg yog txawv. Cov kua muag tuaj yeem yog ib qho kev tsim kua muag ib zaug, los yog lub kua muag los ntawm kev txhim kho ntawm cov kab nrib pleb, uas yog, pom tsis pom.

Yog vim li cas tsom xam: Raws li qhov tseeb qhov teeb meem ntawm qhov chaw, los ntawm kev soj ntsuam lub tearing txoj hauj lwm, puas lub puab thiab degree ntawm crushing ntawm ib feem, nws yog ntseeg hais tias lub tearing thiab skewing tus cwj pwm ntawm ib feem yog feem ntau yog reflected nyob rau hauv lub flanging txoj kev. Cov laj thawj rau qhov txheej txheem no yog raws li hauv qab no:

1. Cov txheej txheem txheej txheem tsis nyob hauv qhov chaw. Thaum lub sij hawm tsim ntawm ib feem, cov txheej txheem yuav tsum tau kom cov tuag, nias lub hauv paus thiab ob qhov chaw yuav tsum tau nyob ze rau ib leeg, thiab cov yas deformation ntawm daim ntawv cov ntaub ntawv yog yuam thaum lub tshuab cuab yeej swb. Tsim. Txawm li cas los xij, vim muaj qhov tsis zoo xws li tsis ruaj tsis khov ntawm qhov chaw nias, nws qhia tau hais tias lub siab ntawm lub tshuab cuab yeej yog nyob rau hauv ib qho kev tsis sib haum ntawm lub siab hloov pauv thaum lub sij hawm tsim khoom. Qhov laj thawj tseem ceeb yog vim li cas cov kws tshaj lij ua haujlwm tsis tau kho lub siab ntawm lub tshuab cuab yeej ntawm lub sijhawm no raws li cov kev xav tau ntawm cov txheej txheem tsim, lossis tsis sib txuas lus cov ntaub ntawv ntawm lub tshuab siab ruaj khov nrog ib leeg thaum lub sijhawm xa khoom ntawm txhua qhov kev hloov, ua rau cov khoom tsis zoo. Ua kom ruaj khov.

2. Qhov tsis xws luag hauv kev tsim cov flanging forming pwm. Cov pwm yog sib koom rau sab laug thiab sab xis ntawm lub pwm nrog ob kab noj hniav. Vim hais tias cov ntsiab lus ntawm cov txheej txheem no tsis yog tsuas yog cov flanging, tab sis kuj yog cov duab tsim cov ntsiab lus. Tsis tas li ntawd, qhov chaw tshwj xeeb yog qhov nyuaj, qhov chaw nkhaus yog nqaim, thiab cov txheej txheem tsim yog concave. Cov pwm nias cov khoom tseem ceeb yog ua raws li cov txheej txheem saum npoo, thiab lwm yam, uas ua rau muaj kev sib txuam loj ntawm cov pwm pwm thiab qhov chaw me me. Hauv kev tsim pwm thawj zaug, tus tsim qauv tsuas yog txiav txim siab txog qhov tshwj xeeb ntawm qhov chaw me me, tab sis tsis quav ntsej cov kev taw qhia swb stroke ntawm blanking core.
