Lub hom phiaj ntawm induction cua sov rauv taws

Lub hom phiaj ntawm induction cua sov cua sov quenching yog raws li nram no:

1. Txhim kho qhov hnav tsis kam ntawm ntu ntu. Induction cua sov cua sov quenching tau xub siv rau saum npoo ntawm phau ntawv xov xwm crankshaft. Nws lub hom phiaj yog txhawm rau txhim kho qhov hnav tsis kam ntawm phau ntawv xov xwm crankshaft. Yav dhau los, lub crankshaft tau ua kom sov thiab ua kom sov, thiab cov cua sov ua kom sov ua kom sov cov ntawv xov xwm crankshaft. Kev ua kom puas yog zoo heev. Cov cams thiab cov ntawv xov xwm ntawm lub cav camshafts thiab cov camshafts ntawm cov twj siv roj tau tag nrho cov carburized thiab tua nyob rau hauv thaum ntxov hnub. Induction cua sov cua sov quenching hloov cov txheej txheem carburizing thiab quenching vim nrawm, tus nqi qis, kev tsim tawm online thiab lwm yam laj thawj. Hauv cov hnub thaum ntxov, cov hlau cam khwb cia hlau tau muab tso ua ke. Induction cua sov quenching hloov txheej txheem qub nrog nws qhov zoo ntawm kev siv tshuab thiab tsim khoom siab.

2. Txhim kho lub zog qaug zog ntawm qhov chaw. Daim ntawv thov ntxiv ntawm induction cua sov rauv quenching yog txhawm rau txhim kho lub zog qaug zog ntawm qhov chaw quenched. Siv EQ1092 lub tsheb ib nrab ncej ua piv txwv. Hauv qab qhov av quab yuam load ntawm 3000N-m, qhov kev sim nkees yog 2 lab lub sijhawm, thiab nws tseem nyob li qub, tab sis qhov qub quenching thiab kev kho kom sov, lub neej qaug zog ntawm ib nrab ncej yog tsawg dua 300,000 zaug; Lwm qhov piv txwv yog qhov txheej txheem qub ntawm lub pob sib koom ua ke thoob ntiaj teb tus pin yog 18CrMnTi steel carburizing thiab quenching, thiab tom qab ntawd nws tau tua los ntawm 45 steel induction cua sov rauv. Kev khoov lub neej tsis muaj zog ntawm cov khoom tau nce los ntawm 80,000 zaug rau ntau dua 2 lab zaug. Crankshaft fillet quenching muab ob npaug rau lub zog qaug zog ntawm crankshaft, thiab qaug zog lub zog ntawm qee yam khoom nce mus txog 700MPa lossis ntau dua.

3. Txo cov cua sov tsis zoo ntawm cov cua sov induction cua sov, tshwj xeeb tshaj yog cov khoom iav. Cov iav carburized muaj qhov txawv txav loj tom qab quenching vim lub sijhawm txheej txheem ntev; thaum lub iav induction cua sov quenching, tshwj xeeb tshaj yog synchronous dual zaus (SDF) iav quenching, muaj cov txheej txheem luv luv thiab cuam tshuam me me, txhim kho cov iav raug thiab txo suab nrov. Hauv peb lub tebchaws, tseem muaj qhov xwm txheej uas cov khoom siv hauv lub cev tau hloov pauv mus rau induction cua sov rauv taws vim qhov txawv txav loj.

4. Siv cov hlau tsis muaj zog los tsim cov zog thiab lwm qhov rau kev txuag hluav taws xob thiab cov khoom siv txuag, thiab lwm yam, rau induction cua sov rauv taws. Thawj yog tias cov hlau tsis muaj cov khoom sib xyaw, uas txuag cov khoom siv, thiab qhov thib ob yog cov cua sov hauv zos thiab tua hluav taws, uas siv sijhawm luv, yog li lub zog txuag hluav taws xob tseem ceeb; kev siv tshuab online ua haujlwm txuag lub zog, tsis muaj kuab paug roj, tsis muaj pa phem tsim kev puas tsuaj, thiab ntau ntxiv tiv thaiv ib puag ncig.

5. Hloov qhov sib sib zog nqus carburizing Sib sib zog nqus carburizing yog txheej txheem nrog lub voj voog ntev thiab siv hluav taws xob siab. Xyoo tsis ntev los no, cov teb chaws txawv teb chaws tau ua tiav siv induction cua sov rauv taws kom hloov nws. Cov txiaj ntsig yog: txo nqi hlau, txuag hluav taws xob, txuag kev ua haujlwm (carburizing thiab txias ua haujlwm sib tsoo), thiab txo qis kev cuam tshuam.

Yog li, cov lus xaus hauv qab no tuaj yeem kos:

1) Cov nplaim hluav taws kub hnyiab ntawm cov khoom ua haujlwm tau ua kom sov los ntawm cov cua sov ua kom sov, uas zoo heev txhim kho qhov hnav tsis kam ntawm thawj qhov haujlwm.

2) Sib piv nrog cov khoom siv sib xyaw ua ke ib txwm muaj, qhov cua sov cua sov ua kom sov qhov chaw tau txhim kho hnav tsis ua haujlwm vim qhov siab tawv tawv thiab tsis muaj decarburization.

3) Qhov hnav tsis kam ntawm cov cua sov ua kom sov ua kom sov qhov chaw ua los ntawm cov pa roj carbon nruab nrab qis dua li ntawm cov carburized quenched qhov chaw vim qhov qis qis tawv thiab cov ntsiab lus carbon.
