Amagiya e-powder metallurgy nemikhiqizo eyenziwe ngokwezifiso, ngokuya ngezidingo ezihlukile zokusebenza komkhiqizo, kufana nokwelashwa okuvamile kokushisa. Ngemuva kokushisa kwe-induction kanye nokucisha, kufanele behlise umoya ukuze banciphise ukucindezeleka kwangaphakathi kanye nokucisha i-brittleness, ukuzinzisa isakhiwo, nokufeza izakhiwo ezidingekayo zemishini. Izinga lokushisa eliphansi ngokuvamile liyenziwa. Izinhlobo ezintathu ze-induction tempering, ukushisa kwesithando somlilo kanye nokuzibamba zivame ukusetshenziswa ekukhiqizeni.
①I-Induction tempering Indwangu yokusebenzela ecishiwe iphinde ishisiswe ngendlela eyi-inductive ukuze kufezwe injongo yokufudumeza, okungukuthi, ngemva kokuba ucezu lokusebenza lushisiswe yi-inductor futhi lupholiswe ngokufuthwayo, ukushisisa nokufudumeza kufanele kwenziwe ngokushesha. Ngenxa yesikhathi esifushane sokushisa, i-microstructure inokusabalalisa okukhulu. Ingathola ukumelana nokugqoka okuphezulu kanye nokuqina komthelela omkhulu, njll. Ifaneleka ngokukhethekile ukuthambisa ama-shafts, imikhono nezinye izingxenye ezihlala zishiswa futhi zicinywe.
②Ukushisa esithandweni Umsebenzi wokusebenzela ubanjiswa esithandweni somgodi, esithandweni sikawoyela noma ezinye izinto zokusebenza ngemva kokucisha imvamisa ephezulu. Izinga lokushisa lokufudumala kufanele linqunywe ngokuya ngobulukhuni obudingekayo kanye nokusebenza, kanye nezinga lokushisa elishisayo kanye nesikhathi, njengamathuluzi ensimbi ekhabhoni ephezulu namathuluzi wokulinganisa, insimbi ye-carbon steel noma i-medium carbon alloy steel gears kanye nama-spline shafts, ama-camshaft ensimbi alloy cast nezinye izingxenye. , idinga izinga lokupholisa eliphansi lokucisha, ngokuvamile isebenzisa ukupholisa ukucwiliswa emanzini noma emanzini. Iningi lazo lithukuthela ngo-150 ~ 250 ℃, futhi isikhathi ngokuvamile singu-45 ~ 120min. Isetshenziswa kakhulu ukuthambisa ama-workpieces anosayizi omncane, umumo oyinkimbinkimbi, udonga oluncane kanye nongqimba olungajulile oluqinile ukuze kuqinisekiswe ukuqina okuphezulu nokumelana nokugqoka kobuso bezingxenye. Dinga.
③Ukuzibamba Misa ukupholisa ngemva kokufafaza noma ukupholisa ukucwiliswa, futhi usebenzise ukushisa okukhona ngaphakathi kwendawo yokusebenza ecishiwe ngemva kokucisha ukuze wenze indawo yokucisha inyukele kuzinga lokushisa elithile futhi ukuze uhlangabezane nezimfuneko zokuthambisa, futhi izinga lokushisa lakhona kufanele libe ngaphezu kwezinga lokushisa elipholile. esithandweni. Ngokuvamile, ingaphakathi lezingxenye liba nezinga lokushisa eliphakeme ngemva kokupholisa amasekhondi angu-3 kuya kwangu-10. Njengesikhathi sokuzithiba, izingxenye ezinkulu zingu-6 futhi ezincane zingu-40s ukuqedela ukuzithiba.
