Kev ntsuas kom txo cov iav high zaus quenching deformation

Cov kev ntsuas los txo cov iav quenching deformation yog kwv yees li hauv qab no:

1) Tiv thaiv lub qhov ntawm lub iav kom tsis txhob shrinking. Muaj ntau lub tshuab cuab yeej cuab tam factories tau sau lawv cov kev paub hauv cheeb tsam no. Qee lub tshuab cuab yeej ua haujlwm xav tau lub qhov hauv lub qhov shrinkage ntawm lub zog kom <0.005mm lossis <0.01mm tom qab quenching. Feem ntau, tom qab high-frequency quenching, lub puab qhov shrinkage feem ntau ncav cuag 0.01-0.05mm; qee qhov chaw tsim khoom yuav Lub puab qhov ntawm lub spline yog preheated ua ntej, thiab tom qab ntawd cov hniav sab nrauv yog quenched; qee qhov chaw ua haujlwm ntxiv cov txheej txheem kub kub rau cov iav tuab-walled tom qab ntxhib tig ntawm cov hniav dawb paug, thiab tom qab ntawd ntxiv cov zaus zaus normalizing kom muaj kev ntxhov siab, thiab tom qab ntawd tiav tig thiab rub lub spline. , Iav txiav, iav shaving, siab zaus quenching, tsis tshua muaj kub tempering, lub puab lub qhov yuav tswj tau kom ntsws nyob rau hauv 0.005mm.

2) Rau cov iav uas quenched hniav los ntawm cov hniav, qhov kawg quenched hniav deforms heev. Yog li ntawd, txoj kev ntawm cov hniav-los ntawm-tus hniav quenching kom txo deformation yog alternated quench, uas yog, cais ib los yog ob tug hniav rau quenching, thiab hniav-los ntawm-tooth quenching txo cov deformation ntawm quenched iav.
