Raws li peb txhua tus paub, hydraulic piston qws yog siv rau kev sib txuas siv dav. Nws cov ntaub ntawv uas feem ntau yog steel hlau xws li 45 steel, 40Cr, 2Cr13, thiab lwm yam, thiab cov hlau no yuav tsum tau ua tiav, xws li electroplating, kev kho cua sov, thiab lwm yam. Txais tshwj xeeb kom tau raws li tej yam xav tau. Li no yog hais tias, kev kho cua sov yog yuav tsum tau txais lub dag zog thiab kev tawv tawv thiab tiv thaiv kom corrosion, txhuam, qaug zog thiab qaug dab peg.
Kev kho cua sov ntawm 45-gauge steel hydraulic piston qws, cov txheej txheem tseem ceeb yog: kev kho cua sov ua ntej kho - tsis tshua muaj siab spheroidizing annealing - quenching - kub quenching - siab quenching. Kev kho kub txheej txheem yog siv los hloov cov qauv hlau thiab hloov kev ua haujlwm los ntawm cua sov, tuav thiab txias lub phaj rau hauv cov khoom hauv lub xeev. Tom qab quenching, cov tawv hardness tuaj yeem ncav 45 ~ 52HRC, thiaj li ua tau txhua yam khoom siv xws li siab zog thiab toughness tau.
40Cr tseem yog cov khoom siv uas nquag siv. Thaum lub sij hawm kub ntawm cov khoom siv hydraulic piston pas nrig, cov txheej txheem tseem ceeb yog: kev kho cua sov ua ntej kho - txo cov kev ntxhov siab ntawm cov khoom ua haujlwm - kev siv quenching thiab tempering - workpiece kuaj xyuas. Los ntawm kom haum zoo, cov yas thiab lub zog ntawm cov hlau tuaj yeem kho, thiab lub zog, qhov nyuaj, lub zog thiab cov khoom zoo yog sib koom ua ke kom tau raws li kev ua haujlwm ntawm cov hydraulic piston qws.http: //xhychromerod.com/
