Raws li peb txhua tus paub, lub hydraulic hydraulic yog ib qho tseem ceeb actuator nyob rau hauv lub hydraulic system ntawm niaj hnub siv cov machinery thiab plays ib qho tseem ceeb heev luag hauj lwm. Raws li ib feem tseem ceeb ntawm hydraulic piston pas nrig zoo kuj yuav cuam tshuam rau kev kawm thiab kev ua hauj lwm tej yam kev mob ntawm lub hydraulic hydraulic. Vim li no, qhov uas yuav tsum tau ua rau ntawm kev ua haujlwm thiab ntau lawm ntawm cov hydraulic piston rods yog tus nruj.
Raws li ib txwm muaj, kom tau raws li kev khiav haujlwm ntawm kev siv hydraulic kheej, hydraulic piston qws siv yuav tsum muaj tsawg kawg yog lub peev xwm los tiv thaiv ntau dua tensile kev nyuab siab. Ua lwm yam lus, nws yuav tsum muaj lub zog txaus, kev nruj, thiab kev muaj zog, thiab tib lub sij hawm, nws yooj yim los tsim hnav vim kev puas tsuaj los ntawm cov khoom uas siv abrasive thaum siv, thiab yuav tsum tau muaj kev sib tw ua rau siab. Feem ntau hauv kev tsim thiab siv ntau lawm, yog kev siv 45 xuab zeb, kev ua haujlwm yog: forging cov ntaub ntawv (dov) - kev txiav - kev sib kho - kev sib xyaw - ntwg hardening, tempering - straightening - taub hau vuam - kev sib tsoo - kev sib tsoo - kev nyuaj siab nyem kev txhim kho (polishing) - polishing - tawv chromium plating - polishing - tu - sib dhos.
Los ntawm cov txheej txheem saum toj no kev txheeb xyuas, nyob rau hauv tus txheej txheem ntawm tsim hydraulic piston pas nrig, kev quenching thiab tempering txheej txheem kuj yog ib qho tseem ceeb sib txuas. Qhov laj thawj yog vim li cas qhov kev kho mob ua kom tsis muaj zog thiab yuav tsum ua kom zoo dua yog qhov ua rau piston pas nrig muaj kev sib txuam txhua yam ntawm kev sib zog, nyuaj, zoo, thiab toughness, thiab tus qauv sab hauv yog lub teeb thiab zoo lub cev nqaij daim tawv sorbite , uas yog txhim kho rau cov quenching tom qab. npaj txhij.
Nws yuav tsum tau muab sau tseg tias thaum tus hydraulic piston qws yog raug quenching thiab tempering, cov txheej txheem tsis yuav tsum tau tswj. Nws feem ntau yog muab ntsia rau ntawm lub cub tawg rau hauv ib hom tshuab zoo hom. Lub ntsuas sov so kub yog 830 ± 10 ° C. Tom qab cua sov txuag rau 160 feeb, nws tau quenched ob zaug thiab quenched ob zaug. Txhua lub sij hawm quenched, nws yog txias los ntawm circulating txias dej thiab oscillated li thiab down thaum lub sij hawm quenching. Ua kom tsis txhob muaj qhov txias tshaj plaws, ua kom txias txog 100 ° C (ncej ua haujlwm tab sis tsis muaj pa luam yeeb) tawm ntawm cov dej mus rau hauv qhov cub kom sov.
Tsis tas li, thaum lub sijhawm ua kom muaj quenching, thiaj li yuav txo tau cov rhaug tshem tawm thiab ntxiv txhim kho lub hydraulic piston qws, ib qho nqi ntawm kev siv quenching ntxiv tuaj yeem ua tiav lub hom phiaj. Thaum quenching, lub twj tso kua dej twj ywm kuj siv los yuam kom cov kua txias rau circulate.http: //www.xhychromerod.com/
