Rockwell hardness testers yog siv los ntsuas qhov hardness ntawm stamped hlau qhov chaw. Cov khoom me me, tsis yooj yim zoo li qub feem ntau muaj qhov chaw sim me me dhau los ua kom haum raws li tus qauv ntawm Rockwell hardness testers.
Stamped part processing encompasses xws li blanking, dabtsi yog khoov, sib sib zog nqus nqus, sib sau, thiab xov. Cov ntaub ntawv siv feem ntau yog kub- dov los yog txias - dov (feem ntau yog txias- dov) cov nplooj ntawv thiab cov strips, suav nrog cov hlau, hlau alloy, caij nplooj ntoos hlav steel, galvanized ntawv, tinplate, stainless hlau, tooj liab thiab tooj liab alloys, thiab txhuas thiab txhuas alloys.
PHP series portable superficial Rockwell hardness testers yog qhov zoo tshaj plaws rau kev sim hardness ntawm cov khoom stamped no. Stamped alloy qhov chaw yog ib qho ntawm cov khoom siv feem ntau hauv kev ua haujlwm hlau thiab kev tsim khoom siv tshuab. Stamping yog cov txheej txheem tsim khoom uas siv cov tuag los sib cais los yog cov ntawv hlau thiab cov strips; nws muaj ntau yam kev siv ntau yam.
Lub hom phiaj tseem ceeb ntawm kev ntsuam xyuas hardness rau cov khoom siv stamping yog los txiav txim siab seb cov ntawv hlau yuav puas tau ua tiav qhov tsim nyog ntawm kev sib tsoo rau cov txheej txheem tom ntej stamping, vim tias kev ua haujlwm stamping sib txawv yuav tsum muaj cov ntawv sib txawv ntawm cov qib hardness. Cov nplooj ntawv aluminium alloy npaj rau stamping tuaj yeem kuaj tau siv Webster hardness tester; Txawm li cas los xij, Barcol hardness tester yuav tsum tau siv yog tias cov khoom tuab tshaj 13 hli, lossis rau cov nplooj ntawv txhuas ntshiab thiab qis - hardness aluminium alloy nplooj ntawv.
Hauv kev lag luam stamping, cov txheej txheem qee zaum hu ua "cov ntawv hlau tsim," txawm tias muaj qhov sib txawv me ntsis. "Sheet hlau forming" yog ib lo lus sib sau ua cov txheej txheem yas uas siv cov ntaub ntawv raw xws li cov ntawv, nyias- cov phab ntsa, thiab nyias nyias; Nyob rau hauv cov txheej txheem no, deformation nyob rau hauv thickness kev taw qhia feem ntau tsis yog ib qho tseem ceeb xav txog.
