QYBZ yog lub tuam txhab ua lag luam txawv teb chaws ua lag luam tag nrho. Kuv tsim cov kabmob ua haujlwm nrog tus nqi qis thiab ua tau zoo.

Cov txheej txheem yooj yim ntawm kev tsim cov kabmob

(Tsom ntsoov rau cov txheej txheem yooj yim ntawm kev tsim khoom ferrule, cov khoom siv yog cov pa roj carbon siab chromium bearing steel Gcr15SiMn)

QYBZ

1. Cov txheej txheem yooj yim ntawm kev tsim cov khoom (pob hlau):

Cov ntaub ntawv nyoos-txias npe-sib tsoo-kho cua sov-nyuaj sib tsoo-kev tshawb fawb ua ntej-pom-zoo tshawb fawb

2. Cov txheej txheem tsim khoom yooj yim ntawm tawb (phaj hlau):

Cov khoom nyoos-txiav cov khoom-txiav lub nplhaib-ua kom zoo-tsim-tsim-xuas nrig ntaus rivet qhov

3. Cov txheej txheem tsim khoom yooj yim ntawm ferrule (lub nplhaib sab hauv, lub nplhaib sab nraud):

Cov khoom siv raw-Forging-Annealing-Turning-Quenching-Tempering-Grinding-Assembly

(1) Forging processing: Forging processing yog thawj zaug ua hauv kev ua cov kabmob ib lub nplhaib, tseem hu ua kev ua tsis tau.

Lub hom phiaj tseem ceeb ntawm lub nplhaib forging ua yog:

(a) Tau txais cov seem zoo ib yam li cov khoom lag luam, yog li ua kom siv cov khoom siv hlau ntau dua, txuag cov ntaub ntawv raw, txo tus nqi ntawm kev ua haujlwm thiab txo tus nqi.

(b) Txhim kho qhov tsis xws luag ntawm cov hlau, txhim kho cov qauv hlau, ua kom cov hlau ua kom muaj kev faib khoom tsim nyog, thiab cov hlau nruj yog qhov zoo, yog li ua rau kev pabcuam lub neej ntawm cov kabmob.

Txoj kev forging: Feem ntau, kev khiav haujlwm tau ua tiav hauv cov khoom siv sib txuas lub cev tsim los ntawm cov cua sov ua kom sov, xovxwm, lub tshuab rov ua haujlwm thiab lub tshuab ua kom zoo.

(2) Kev tshem tawm: Lub hom phiaj tseem ceeb ntawm lub nplhaib annealing yog: spheroidizing annealing ntawm high-carbon chromium bearing steel yog kom tau txais cov qauv nrog nplua, me me, zoo ib yam thiab puag ncig carbide hais txog qhov sib npaug faib rau ntawm ferrite matrix, rau yav tom ntej Ua haujlwm txias thiab Qhov kawg quenching thiab tempering yog siv rau kev npaj lub koom haum.

Cov txheej txheem yooj yim ntawm kev pleev xim Gcr15SiMn:

Rwb thaiv tsev ntawm 790-810 ℃ rau 2-6h, txias rau hauv qab 600 ℃ ntawm 10-30 ℃/h, cua txias tawm ntawm lub cub tawg

(3) Kev ua tig: Kev ua tig yog kev ua tiav cov khoom tiav ib nrab ntawm cov nplhaib sib dhos, uas tuaj yeem hais tau tias yog tsim ua.

Lub hom phiaj tseem ceeb ntawm kev xa cov txheej txheem yog:

(a) Ua cov txheej txheem ferrule zoo ib yam li cov khoom kawg.

(b) Tsim cov xwm txheej zoo rau cov txheej txheem sib tsoo tom ntej.

Txoj kev tig:

Txoj hauv kev txheej txheem txheej txheem: ua tiav cov khoom me me ntawm txhua txoj kev xa mus ntawm ib qho khoom siv.

Txoj kev faib cov txheej txheem: kev tsim khoom ntau ntawm qee yam 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.

QYBZ 4

Lub hom phiaj tseem ceeb ntawm kev kho cua sov yog:

(a) Hloov cov qauv khoom los ntawm kev kho cua sov thiab 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), yog li ua rau 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 tempering quenching:

Cua sov kub: 820-840 (℃) Lub sijhawm tuav: 1-2h Cua txias nruab nrab: roj Tsawg kub kub:

Cua sov kub: 150-180 (℃) Lub sijhawm tuav: 2-5h Txoj kev txias: cua txias

(5) Kev 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 cov ferrule ua tau raws li cov qauv tsim.

(b) Muab cov nplhaib tsim nyog thiab cov nplhaib rau sib dhos ua ke.

Kev sib tsoo txheej txheem: Feem ntau, nws tau ua tiav los ntawm txheej txheem txheej txheem tawg. Nws kuj tseem tuaj yeem txuas ntau yam khoom siv los ntawm kev thauj khoom thiab tshem tawm cov cuab yeej los tsim cov kab ntau lawm rau kev ua kom txhim kho kev ua haujlwm tau zoo.

(6) Kev sib dhos cov kabmob: Kev sib dhos cov kabmob yog txheej txheem zaum kawg hauv cov txheej txheem kev tsim khoom, uas muaj qhov cuam tshuam tseem ceeb rau kev ua tau zoo.

Lub hom phiaj tseem ceeb ntawm kev sib dhos kabmob yog:

(a) Sib sau ua ntu (lub nplhaib sab hauv, lub nplhaib sab hauv, cov menyuam thiab lub tawb) ua tiav los ntawm ntau cov txheej txheem rau cov khoom lag luam.

(b) Raws li kev xav tau sib txawv, nws tuaj yeem sib sau ua cov khoom lag luam nrog ntau yam kev txiav txim siab, ntau yam kev pom zoo thiab lwm yam tshwj xeeb xav tau.
