Menene hanyoyin kashewa da aka saba amfani da su don high m quenching kayan aiki

Hanyoyin quenching da aka saba amfani da su don kayan aikin kashe mitoci masu yawa sune:

1. Single matsakaici quenching

Amfanin quenching guda-matsakaici shine cewa yana da sauƙin aiki, amma ya dace da ƙananan kayan aiki da ƙananan nau’i-nau’i, kuma yana da haɗari ga manyan nakasawa da fashe don manyan kayan aiki masu girma.

2. Biyu matsakaici quenching

Matsakaicin quenching sau biyu shine don dumama kayan aikin don austenitize sannan a nutsar da shi a cikin matsakaici tare da ƙarfin sanyaya mai ƙarfi. Lokacin da canji na tsarin martensite yana gab da faruwa, nan da nan an canza shi zuwa matsakaici tare da raunin sanyi don ci gaba da sanyaya. Gabaɗaya, ana amfani da ruwa azaman matsakaicin sanyaya mai saurin kashewa, kuma ana amfani da mai azaman matsakaicin sanyin sanyi. Wani lokaci ana iya amfani da quenching ruwa da sanyaya iska. Matsakaicin matsakaici sau biyu na iya mafi kyawun hana nakasar aiki da fashewa. Manyan carbon karfe workpieces su dace da quenching ta wannan hanya.

3, quenching mai daraja

Wannan hanyar quenching yana rage ƙarfin quenching saboda daidaiton zafin jiki a ciki da waje na workpiece kuma yana kammala canjin martensitic a ƙarƙashin jinkirin yanayin sanyaya, don haka yadda ya kamata rage ko hana nakasawa da fashe kayan aikin, kuma yana shawo kan wahalar sarrafa ruwa. da mai a cikin matsakaici-matsakaici quenching. Kasawa. Duk da haka, saboda yawan zafin jiki na matsakaicin sanyaya a cikin wannan hanyar quenching, yawan sanyaya kayan aiki a cikin wanka na alkali ko wanka na gishiri yana jinkirin, don haka lokacin jira ya iyakance, kuma yana da wahala ga manyan sassan sassa. kai m quenching rate. kananan workpiece.

4. Isothermal quenching

Austempering na iya rage lalacewa da fashewar kayan aikin, kuma ya dace da sarrafa hadaddun, madaidaici da mahimman sassa na inji, irin su kyawu, kayan aiki, da gears. Kamar quenching mai daraja, quenching isothermal za a iya amfani da shi kawai ga ƙananan kayan aiki. Matsakaici da babban mitar quenching inji kayan aiki kayan aiki ya kamata yanke shawarar abin da quenching hanya don amfani bisa ga workpiece kana bukatar ka quench. Hakanan ana iya samun ƙananan kayan aiki tare da kashe kafofin watsa labarai guda ɗaya.

Baya ga hanyoyin kashe wutar lantarki da ke sama a cikin aikin kashe na’urori masu saurin kashe wutar lantarki, an ɓullo da sabbin hanyoyin kashe ƙarfi da yawa don haɓaka ƙarfi da taurin ƙarfe a cikin ‘yan shekarun nan, kamar kashe zafi mai zafi, saurin kashe dumama keken keke. da dai sauransu.
