Txoj kev dav dav ntawm cov cua sov induction cua sov

Siv thawj induction cua sov cua sov rau kev tua hluav taws thiab cua sov, nrog cov cuab yeej siv hluav taws xob qub, kev ua kom sov yog ua los ntawm kev txo hwj chim. Qhov zoo ntawm txoj kev no yog qhov txheej txheem quenching thiab tempering tau ua tiav hauv ib qho kev thauj khoom thiab tshem tawm; tab sis vim tias qhov chaw nres tsheb quenching tau nyob, qhov kev ua kom tawg tau raug txo.

1. Ib qho piv txwv ntawm cov txheej txheem no tau siv rau cov khoom me me no xws li cov tsheb maus taus. Tom qab ib nrab-axis scanning hardening, 1/6 ~ 1/5 ntawm qhov nruab nrab zaus qhov hluav taws xob ntawm cov txheej txheem quenching nrog tib tus inductor tau siv rau kev ntsuas qhov ntsuas kub. Qhov tsis zoo yog tias nyob rau hauv qhov kub tsis txias, qhov tam sim no ntawm qhov qub quenching cua sov fais fab mov yuav tsum siab dua qhov tsim nyog zaus. Yog li ntawd, qhov kub ntawm txheej tawv tawv nyob ntawm qhov ua kom sov, thiab nws cov cua sov ua haujlwm tau qis.

2. Siv lwm txheej uas tsim nyog qis dua induction cua sov rauv thiab inductor rau qhov kub. Txoj kev no tau siv dav tam sim no. Vim tias qhov kub thiab txias ntawm qhov ua kom tawv tawv qhov qis yog qis dua Curie point, thiab feem ntau ntawm lawv qis dua 300 ℃. Lub sijhawm no, qhov nkag mus tob tob ntawm qhov kub tsawg feem ntau yog 1/10 ntawm qhov nkag mus tob tam sim no ntawm 800 ° C. -1/40 Yog li, qhov tam sim no tau xaiv rau qhov ua kom sov lub tshuab ua haujlwm qis dua li qhov tam sim no thaum lub sij hawm quenching thiab cua sov. Nws yog ib txwm siv 1000 ~ 4000Hz. Qee tus siv lub zog siv ncaj qha, xws li lub tog raj kheej liners thiab flywheel ring gear.

Tempering inductors feem ntau siv ntau qhov tig, qhov sib txawv nruab nrab ntawm lub nplhaib ua haujlwm tau zoo thiab cov haujlwm ua haujlwm tau nthuav dav, thiab thaj tsam ntawm qhov ua rau lub siab feem ntau loj dua thaj chaw quenched. Thaum ib nrab-ncej txais yuav cov txheej txheem quenching, nws qhov kub kuj tseem lees txais induction tempering. Lub sijhawm no, lwm lub zog siv hluav taws xob qis dua tau siv, thiab ntau qhov tig inductor siv los ua cua sov thiab ua kom sov ib zaug.
