1. txheej txheem forging. Qhov no yog ib kauj ruam tseem ceeb hauv kev tsim cov yas pwm ua haujlwm. Rau cov pwm yas ua los ntawm cov hlau alloy siab, cov kev xav tau feem ntau yog muab tso rau pem hauv ntej rau kev faib cov carbides thiab lwm yam metallographic qauv hauv cov khoom. Tsis tas li ntawd, qhov kub ntawm forging yuav tsum nruj me ntsis tswj, qhov tseeb cua sov specifications yuav tsum tau tsim, txoj kev forging quab yuam yuav tsum tau siv, thiab qeeb txias los yog raws sij hawm annealing tom qab forging yuav tsum tau nqa tawm.
2. Npaj rau kev kho cua sov. Kev npaj cov txheej txheem kev kho cua sov xws li annealing, normalizing, lossis quenching thiab tempering yuav tsum tau txais raws li cov khoom sib txawv thiab cov kev xav tau ntawm cov pwm pwm ua haujlwm, txhawm rau txhim kho cov qauv, tshem tawm cov qauv tsis xws luag ntawm forged blanks, thiab txhim kho cov txheej txheem ua haujlwm. . High carbon alloy pwm steel tuaj yeem tshem tawm kev sib txuas ntawm cov carbides los yog saw carbides los ntawm kev npaj kho cua sov kom tsim nyog, ua carbides spheroidized thiab refined, thiab txhawb kev sib koom ua ke ntawm carbide faib. Qhov no yog qhov zoo rau kev ua kom zoo ntawm quenching thiab tempering, thiab txhim kho lub neej kev pab cuam ntawm pwm.
3. Quenching thiab tempering. Qhov no yog ib kauj ruam tseem ceeb hauv kev kho pwm kub. Yog hais tias overheating tshwm sim thaum lub sij hawm quenching thiab cua sov, nws tsis tsuas yog ua rau ib tug tseem ceeb brittleness ntawm lub workpiece, tab sis kuj yooj yim ua rau deformation thiab tawg thaum lub sij hawm txias, heev cuam tshuam rau lub neej kev pab cuam ntawm pwm. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tiv thaiv oxidation thiab decarburization thaum quenching thiab cua sov ntawm stamping tuag. Cov txheej txheem kev kho cua sov tshwj xeeb yuav tsum tau tswj nruj me ntsis. Yog tias muaj kev tso cai, lub tshuab nqus tsev kho cua sov tuaj yeem siv tau. Tom qab quenching, lub sij hawm tempering yuav tsum tau ua, thiab txawv tempering txheej txheem yuav tsum tau saws raws li cov kev cai.
4. Kev ntxhov siab ntxhov siab annealing. Tom qab ua cov pwm yas pwm, kev ntxhov siab kho annealing yuav tsum tau nqa tawm kom tshem tawm cov kev ntxhov siab sab hauv los ntawm kev ua haujlwm ntxhib, txhawm rau kom tsis txhob muaj ntau deformation thiab tawg los ntawm quenching. Rau cov pwm uas yuav tsum tau muaj siab precision, yuav tsum tau muaj kev ntxhov siab kho tempering tom qab sib tsoo los yog hluav taws xob machining, uas yog qhov zoo rau stabilizing pwm raug thiab txhim kho kev pab cuam lub neej.
