Txoj kev kuaj cov hlau stamping yog muab faib rau cov khoom siv twv thiab cov thwj cim kev ntsuam xyuas, hlau stampings feem ntau xaiv Rockwell hardness tester. Me me, stamped qhov chaw nrog ib hom khoom hnyav tuaj yeem siv los kuaj lub dav hlau me me, tsis tuaj yeem kuaj tau ntawm lub rooj zaum ntawm Rockwell hardness tester. Qhov laj kab paj nruag Rockwell Portwell Rockwell Hardness Tester yog qhov zoo tshaj plaws rau kev ntsuam xyuas qhov nyuaj ntawm cov khoom ntaiv no. Cov stamping cov thooj txeem feem ntau yog siv rau hauv cov hlau ua thiab txhua yam khoom tsim hluav taws xob. Kev thev ua qhov kev ua haujlwm yog txoj kev ua uas siv cov pwm los ua cov hlau phaj lossis kev sib sau. Nws siv yog loj heev.
1, qhov chaw ntawm qhov khoom kho qhov muag ntawm qhov kev xeem tawv tawv
Cov kev sib tw ntawm cov ntaub ntawv cov ntaub ntawv, lub hom phiaj xav ntawm lub chaw ua haujlwm hlau ua haujlwm yog txiav txim siab seb puas muaj cov ntawv nplaum ntawm cov ntawv hlau yuav yog qhov tsim nyog rau kev ua cov khoom tom ntej. Qhov sib txawv ntawm cov khoom siv sib txawv, qhov kev thov tsis yog tib qho kev sib tw. Aluminium alloy phaj siv rau stamping qhov chaw ua yuav kuaj nrog Vickers hardness tester. Thaum cov ntaub ntawv tuab yog ntau dua 13 hli, ces Brinell tawv tester siv tau. Rau cov ntshiab txhuas phaj los yog cov lowness aluminium alloy phaj, Brinell hardness tester yuav tsum tau siv.
2, kev sojntsuam nrig txog kev kho mob hnyav
Thawj cov ntaub ntawv rau kev thwj rau khoom yog tuag hlau (nrog rau cov cuab yeej hlau thiab kev kub ceev) thiab qee zaus carbide.
Cov thwj cim feem ntau yuav tsum muaj kev kub ntxhov thiab hnav ua haujlwm, thiab kev kho kom sov yog qhov tseem ceeb.
