Vim li cas cov workpiece deformed thaum rhaub los ntawm cov khoom siv tawv tawv?

cov induction cov khoom ua kom tawv tawv ua kom lub cev ua haujlwm nrawm heev, thiab cua sov zoo ib yam, uas tsuas yog ua tau raws li kev siv ntau yam khoom siv ntxiv rau kev tua. Nws yog los ntawm kev ua kom sov sai thiab txias sai ntawm cov khoom siv hlau kom tau txais tsuas yog txheej txheej tawv tawv li martensite. Peb tsuas tuaj yeem siv ntau txoj hauv kev los tswj tus nqi deformation, tab sis qhov teeb meem ntawm kev ua haujlwm deformation tsis tuaj yeem raug tshem tawm tag nrho.

1. Forging thiab ua

Thaum cov khoom siv hluav taws xob ua kom sov ua kom sov, cov khoom ua haujlwm yuav tsim cov deformations sib txawv. Thov ua raws txoj hauv kev los tiv thaiv nws.

Thaum ua haujlwm cov crankshafts, fiber ntau ntws yog vim kev hloov pauv hauv cov qauv txheej txheem. Qee qhov ua tiav tsawg dua, tab sis qee qhov ua tiav ntau dua.

2. Txias tsis sib xws

Yog tias cov roj quenching tuaj yeem ntws sib npaug los ntawm txhua qhov ua haujlwm, tom qab ntawd txhua qhov ua haujlwm thiab ntu ntawm cov haujlwm sib txawv ntawm cov haujlwm tuaj yeem ua kom txias txias, uas tseem yog txoj hauv kev tseem ceeb tshaj plaws los tiv thaiv kev hloov pauv ntawm cov haujlwm.

Thaum cov khoom sib dhos sib zog ua kom tawv los ntawm cov khoom siv tawv tawv, yog tias cov nplaim hluav taws thiab cov ncej tsis nyob ntawm ib qho kab nruab nrab thiab qhov deb ntawm qhov chaw txau dej tsis sib xws, qhov hloov pauv yuav nce ntxiv tom qab tua. Ntxiv rau kev kho qhov ua kom txias txias tsis sib xws, koj tuaj yeem hla Ntxiv txhawm rau tiv thaiv kev deformation rau clamp.

Peb, siab

Cov ncej yuav ncab thaum ua kom sov los ntawm cov khoom siv tawv tawv. Yog tias qhov elasticity tsis zoo, lossis txawm tias qhov elasticity zoo, cov khoom yuav khoov thiab deformed vim muaj lub siab ntau dhau lossis ntev ntev.

Plaub, tus qauv tsis tsim nyog

Hauv cov qauv tsim, nws yog qhov tsim nyog kom tsis txhob muaj cov duab asymmetrical thiab cov ntu tsis sib xws, nrog rau cov kauj ruam sib txawv kom me me li sai tau, thiab hloov pauv tau yooj yim nrog cov kab ncig ntawm cov ces kaum.

Tsib, kev nyuaj siab

Nrog cov txheej txheem hauv qab no, peb tuaj yeem txo qhov deformation ntawm cov khoom ua haujlwm tom qab induction hardening. Kev paub dhau los tau qhia tias yog tias txheej txheem kub ua kom sov ntxiv rau hauv qhov chaw ua haujlwm tom qab ua haujlwm, kev ua haujlwm nyuaj thiab ua kom ncaj ncaj ua ntej tso tawm tuaj yeem tshem tawm.
