1. Forging ua
Forging yog thawj qhov kev ua ntawm cov nplhaib ua, tseem hu ua kev ua tsis tiav. Lub hom phiaj tseem ceeb ntawm ferrule forging yog:
(a) Cov khoom seem zoo ib yam li cov khoom tau txais, yog li txhawm rau txhim kho kev siv cov khoom siv hlau, txuag cov ntaub ntawv raw, txo tus nqi ntawm kev ua haujlwm thiab txo tus nqi (b) Tshem tawm qhov tsis xws sab hauv ntawm cov hlau, txhim kho cov qauv hlau, ua kom cov hlau xa cov khoom faib tawm tsim nyog thiab cov hlau nruj, zoo li txhawm rau txhim kho kev pabcuam lub neej ntawm cov kabmob. Txoj kev forging: feem ntau, kev khiav haujlwm tau ua tiav hauv cov cuab yeej lub cev tsim los ntawm induction cua sov rauv, nias, reamer thiab tsim lub tshuab.
2. Anneal
Lub hom phiaj tseem ceeb ntawm kev txhuam cov ferrule yog:
Spheroidizing annealing ntawm high carbon chromium bearing steel yog kom tau txais cov microstructure nrog zoo, me me, zoo ib yam thiab puag ncig carbide hais sib npaug faib rau ntawm ferrite matrix, thiaj li npaj cov microstructure rau yav tom ntej txias ua hauj lwm thiab kawg quenching thiab tempering.
3. Tig
Txoj siav yog ib nrab ua tiav ntawm cov kabmob ib puag ncig, uas tuaj yeem hais tau tias yog tsim ua. Lub hom phiaj tseem ceeb ntawm kev tig yog:
(a) Ua cov txheej txheem ferrule zoo ib yam li cov khoom kawg (b) Tsim cov xwm txheej zoo rau kev sib tsoo tom ntej. Txoj kev tig: txoj hauv kev txheej txheem: txheej txheej me me ntawm txhua txoj kev xa mus ntawm ib qho khoom siv. Txheej txheem txheej txheem kev faib ua feem: kev tsim khoom ntau ntawm cov txheej txheem tig ntawm ib qho khoom siv.
4. Kev kho cua sov
Kev kho cua sov yog txheej txheem txheej txheem tseem ceeb txhawm rau txhim kho sab hauv ntawm cov kabmob. Lub hom phiaj tseem ceeb ntawm kev kho cua sov yog:
(a) Cov txheej txheem microstructure tau hloov pauv los ntawm kev kho cua sov txhawm rau txhim kho cov khoom siv dag zog ntawm cov khoom (b) Txhim kho sab hauv ntawm cov kabmob (hnav tsis kam, lub zog thiab tawv), txhawm rau txhim kho kev pabcuam lub neej ntawm cov kabmob . Rau cov pa roj carbon siab chromium bearing steel GCr15SiMn, kev kho cua sov suav nrog quenching thiab qis kub kub quenching:
Cua sov kub: 820-840 (℃) tuav lub sijhawm: 1-2h txias nruab nrab: roj qis kub kub:
Cua sov kub: 150-180 (℃) tuav lub sijhawm: 2-5h txias hom: cua txias
5. Sib tsoo
Kev sib tsoo yog qhov ua tiav hauv kev ua cov kabmob thiab cov menyuam, uas yog hu ua cov khoom tiav.
Lub hom phiaj tseem ceeb ntawm kev sib tsoo yog:
(a) Ua kom qhov tseeb qhov tseeb thiab cov duab zoo ntawm ferrule ua tau raws li cov qauv tsim qauv (b) Muab cov khoom tsim nyog thiab rau kev sib dhos. Txoj kev sib tsoo: nws yog feem ntau ua tiav los ntawm kev faib cov txheej txheem, lossis ntau yam khoom siv tuaj yeem txuas nrog los tsim cov kab ntau lawm los ntawm kev thau khoom thiab tshem tawm cov cuab yeej los txhim kho kev ua haujlwm tau zoo.
6. Sib dhos ua ke
Kev sib dhos cov kabmob yog txheej txheem kawg hauv txheej txheem kev tsim khoom, uas muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm ntawm kev coj tus kheej.
Lub hom phiaj tseem ceeb ntawm kev sib dhos kabmob yog:
(a) Cov ntu ua tiav los ntawm ntau cov txheej txheem (lub nplhaib sab hauv, lub nplhaib sab hauv, cov menyuam thiab lub tawb) tau sib sau ua cov khoom lag luam.
(b) Raws li kev xav tau sib txawv, nws tau sib sau ua cov khoom lag luam nrog ntau yam raug, ntau yam kev pom zoo thiab lwm yam tshwj xeeb xav tau.
