Cov ntaub ntawv dab tsi yog siv rau kev ua thiab tsim tshuaj txhaj pwm?

Peb paub tias qhov zoo ntawm kev ua cov yas thiab kev txhaj tshuaj pwm yog nyob ntawm qee yam ntawm cov khoom nws xaiv. Kev ua thiab kev txhaj tshuaj pwm yog ib qho tseem ceeb ntawm cov yas molding thiab kev ua, thiab qhov feem ntawm tag nrho cov pwm tso tawm tus nqi yog nce txhua xyoo. Raws li kev txheeb cais, Kev ua thiab kev tsim cov pwm txhaj tshuaj yog kwv yees li 33 feem pua ​​​​ntawm tag nrho cov pwm pwm. Yog li ntawd, daim ntawv thov ntawm kev ua thiab kev txhaj tshuaj molds yog qhov tseem ceeb nyob rau hauv lub teb chaws kev lag luam. Lub ntsiab tseem ceeb cuam tshuam rau lub neej ntawm cov pwm yas yog: pwm qauv, pwm cov khoom, pwm ua haujlwm zoo, pwm ua haujlwm, cov khoom seem, thiab lwm yam, lub sijhawm no, cov yam ntxwv ntawm pwm khoom nws tus kheej thiab kev kho cua sov ua lub luag haujlwm tseem ceeb. Feem ntau siv ua thiab tsim cov ntaub ntawv txhaj tshuaj pwm

Tam sim no, feem ntau carbon steel pwm steels tau dav siv vim nws tus nqi qis, siv tau yooj yim thiab qee yam kev ua haujlwm. Ntxiv nrog rau cov yas pwm hlau, nws kuj suav nrog lwm cov pwm hlau xws li pre-hardened yas pwm steel. Muaj ntau cov pwm hlau. Tam sim no, feem ntau siv pwm steels muaj xws li pre-hardened yas pwm steel, carburized yas pwm steel thiab hnub nyoog-hardening yas pwm steel. Pre-hardened yas pwm steel yog qhov ib txwm hardness rau kev ua steel daim ntaub ntawv, hom steel no zoo heev txiav kev ua tau zoo thiab yuav ncaj qha kab noj hniav machined.

Kev xaiv cov khoom xav tau rau kev ua thiab kev txhaj tshuaj pwm

1. Kev ua haujlwm polishing zoo heev

Cov khoom zoo txhaj tshuaj molded cov khoom yuav tsum muaj qhov me me roughness tus nqi ntawm cov kab noj hniav. Piv txwv li, tus nqi nto roughness ntawm qhov txhaj tshuaj pwm kab noj hniav yuav tsum tsawg dua Ra0.1-0.25, thiab qhov chaw kho qhov muag yuav tsum yog Ra<0.01nm. the="" cavity="" must="" be="" polished="" to="" reduce="" the="" surface="" roughness="" value.="" for="" this="" reason,="" the="" selected="" steel="" requires="" less="" material="" impurities,="" fine="" and="" uniform="" arrangement,="" no="" fiber="" orientation,="" and="" no="" pitting="" or="" orange="" peel="" defects="" during="">

2. Zoo heev thermal stability

Cov duab ntawm qhov chaw ntawm cov yas txhaj tshuaj pwm yog feem ntau nyuaj thiab nyuaj rau txheej txheem tom qab quenching. Yog li ntawd, cov khoom uas muaj thermal stability zoo yuav tsum tau xaiv kom deb li deb tau. Thaum cov pwm yas raug kho cua sov, cov coefficient ntawm linear expansion me me, kev kho cua sov deformation me me, tus qauv hloov tus nqi tshwm sim los ntawm qhov kub thiab txias sib txawv me me, cov txheej txheem metallographic thiab pwm qauv yog ruaj khov, thiab nws tuaj yeem txo. los yog tsis ua tiav los xyuas kom meej cov txheej txheem pwm yas. Qhov tseeb thiab qhov xav tau ntawm qhov roughness.
