Pwm Phau Ntawv Qhia Npib Ua Haujlwm thiab Cov Kev Ntseeg
Pwm Hij Choj Pins yog ib qho tseem ceeb tivthaiv ntawm cov pwm. Lawv lub luag haujlwm tseem ceeb yog kom ruaj ntseg cov pwm phaj thiab xyuas kom ruaj khov thaum lub sijhawm ua haujlwm. Ua raws li lawv daim ntawv thov thiab kev coj ua, pwm coj cov lus qhia rau cov lus qhia, thiab kev coj ua pneumatic pneatatic.
Pwm Phau Ntawv Qhia Npaib Khoom Xaiv
Cov Pwm Qhia Txog Pwm Phau Ntawv Qhia muaj xws li cov roj carbon zoo tib yam steel, alloy txheej txheem hlau, thiab stainless hlau. Cov ntaub ntawv sib txawv muaj cov khoom sib txawv thiab cov ntawv thov.
1. Tib yam carbon cov qauv hlau
Cov qauv siv carbon zoo tib yam ntawm cov qauv hlau yog hais txog cov qauv hlau nrog cov ntsiab lus carbon uas tsis muaj ntau tshaj 0.25%. Nws ua rau lub zog siab thiab hnav tsis kam. It is widely used in low-load, small, and medium-sized molds. Nws lub hardness feem ntau nyob ib ncig ntawm HRC 28-32.
2. Alloy Txheej Txheem Hlau
Alloy qauv hlau txuas yog hais txog cov qauv hlau uas lawv cov khoom yog txhim kho los ntawm kev sib ntxiv ntawm cov ntsiab lus ntawm alloying. Nws ua rau lub zog siab, hardness, thiab corrosion tsis kam. Nws yog feem ntau siv nyob rau hauv cov pwm loj nrog cov kev xav tau. Nws lub hardness feem ntau nyob ib ncig ntawm HRC 35-50.
3. Stainless hlau
Stainless hlau muaj cov yam ntxwv zoo xws li corrosion tsis kam thiab coj kev tiv thaiv. Nws yog feem ntau siv nyob rau hauv high-}} cov pwm. Nws lub hardness feem ntau nyob ib ncig ntawm HRC 30-40.
Xaiv lub hardness ntawm pwm coj tau pins
Lub hardness ntawm cov pwm pwm Pins yog nyob ntawm cov yam xws li kev siv cov xwm txheej, chaw ua haujlwm, thiab xaiv cov khoom xaiv. Feem ntau hais lus, dhau lub hardness tuaj yeem ua rau deformation thiab hnav, thaum siab dhau lub hardness tuaj yeem ua rau tawg thiab tawg. Feem ntau hais lus, lub hardness ntawm kev coj ua pins yuav tsum nyob nruab nrab ntawm 70% thiab 85% ntawm cov khoom siv tawv. Qhov kev xaiv tseem yuav tsum tau ua raws cov kev txiav txim siab tshwj xeeb, xws li pwm lub pob, kev siv kev siv, thiab kev tsim ntau lawm.
