Hlau tiv thaiv npog, Plhaub txheej, Hlau Stamping qhov chaw, Sheet Hlau Progressive Stamping Tuag

Stamping tuag yog cov txheej txheem tseem ceeb ntawm cov khoom siv hauv stamping txoj kev, thiab lawv cov kev pabcuam ncaj qha txiav txim siab qhov tseeb ntawm qhov chaw stamped thiab kev ua haujlwm ntawm cov kab ntau lawm. Cov khoom ntawm cov khoom siv hauv paus matrix, microstructure thiab cov khoom ntawm cov weld overlay, thiab kev sib txuas ntawm lub xeev ntawm ob qho tib si txiav txim siab tag nrho cov kev pab cuam lub neej thiab tsim kev ruaj ntseg ntawm cov tuag. Daim ntawv no tau txheeb xyuas qhov sib txuam ntawm cov khoom siv hauv paus thiab cov khoom siv weld overlay rau stamping tuag, muab lub hauv paus rau kev txhim kho tag nrho cov kev pabcuam kev tuag.

Lub hauv paus xaiv cov khoom siv tsom rau hardness, cuam tshuam toughness, thiab lub zog ntawm cov qauv. High- carbon steel, Cr12MoV, SKD11, thiab lwm yam hlau cov cuab yeej hlau yog feem ntau siv cov ntaub ntawv hauv paus, uas yuav tsum muaj cov khoom txaus-cov kabmob muaj peev xwm thiab deformation tsis kam hloov mus rau qhov hloov pauv thiab cuam tshuam sai thaum lub sij hawm stamping, kom ruaj khov ntawm cov qauv matrix.

Vuam cov ntaub ntawv tsom rau kev ntxiv dag zog rau saum npoo, tsom mus rau kev ua kom tau raws li qhov yuav tsum tau ua rau hnav tsis kam, thermal shock resistance, thiab tiv thaiv - adhesion zog. High- alloy vuam hlau los yog hmoov hlau alloy feem ntau yog siv los ua cov khoom siv vuam, tsim cov txheej txheem ntxiv rau ntawm qhov tseem ceeb xws li kev tuag txiav ntug thiab tsim nto los ntawm cov txheej txheem vuam. Lub hardness thiab toughness ntawm weld overlay yuav tsum haum haum rau lub hauv paus cov ntaub ntawv kom tsis txhob interfacial bonding tsis ua hauj lwm, nto tev, los yog lub zos deformation vim muaj ntau yam kev ua tau zoo sib txawv.

Sib piv cov thermal expansion coefficients ntawm cov khoom siv hauv paus thiab cov weld overlay yog qhov tseem ceeb rau kev ruaj ntseg interfacial. Kev sib txawv ntau dhau ntawm lawv cov thermophysical tsis tuaj yeem ua rau muaj kev ntxhov siab tseem ceeb hauv lub sijhawm vuam txias, ua rau muaj qhov tsis xws luag xws li microcracks thiab tev tawm hauv cov weld overlay. Thaum xaiv cov khoom siv, qhov ntsuas kub tsis zoo ntawm cov ntaub ntawv yuav tsum raug muab sib xyaw thiab txheeb xyuas kom ntseeg tau tias kev sib raug zoo ntawm kev sib raug zoo nyob rau hauv qhov kub hloov pauv.

Tib lub sijhawm, cov txheej txheem weld overlay tsis cuam tshuam ncaj qha rau cov khoom sib txuam. Los ntawm kev ua kom zoo tshaj qhov kub thiab txias, vuam cov khoom siv hluav taws xob, vuam ceev, thiab tom qab-weld heat treatment regime, residual welding stress yuav txo tau zoo, lub interfacial metallurgical bonding state txhim kho, thiab tag nrho cov kev sib txuas lub zog ntawm lub hauv paus khoom thiab weld overlay enhanced.
