Iigiya zesinyithi kunye neemveliso ezenziwe ngokwezifiso, ngokweemfuno ezahlukeneyo zemveliso, ziyafana nonyango oluqhelekileyo lobushushu. Emva kokufudumeza kwe-induction kunye nokucima, kufuneka bahlanjululwe ukunciphisa uxinzelelo lwangaphakathi kunye nokucima i-brittleness, ukuzinzisa isakhiwo, kunye nokufezekisa iipropati ezifunekayo zomatshini. Ubushushu obuphantsi bobushushu buqhele ukwenziwa. Iintlobo ezintathu ze-induction tempering, i-furnace tempering kunye nokuzibamba zihlala zisetyenziswa kwimveliso.
①I-Induction tempering I-workpiece ecinyiweyo iphinda ifudunyezwe ukufezekisa injongo yokufudumala, oko kukuthi, emva kokuba i-workpiece ifudunyezwe yi-inductor kunye ne-spray-cooled, ukufudumeza kwe-induction kunye nokufudumeza kufuneka kwenziwe ngokukhawuleza. Ngenxa yexesha elifutshane lokufudumeza, i-microstructure ine-dispersion enkulu. Iyakwazi ukufumana ukuxhathisa ukunxiba okuphezulu kunye nokuqina kwempembelelo ephezulu, njl njl. Ifaneleka ngakumbi ukufudumala kweeshafts, imikhono kunye nezinye iindawo ezihlala zifudumala kwaye zicinywa.
②Ukushisa kwisithando somlilo Umsebenzi owenziweyo ugxininiswe kwisithando somlilo, i-oyile okanye ezinye izixhobo emva kokucima i-high-frequency quenching. Ubushushu bobushushu kufuneka bumiselwe ngokobulukhuni obufunekayo kunye nokusebenza, kunye neqondo lobushushu kunye nexesha, njengezixhobo eziphezulu zekhabhoni zentsimbi kunye nezixhobo zokulinganisa, intsimbi yekhabhoni ephakathi okanye intsimbi yentsimbi ephakathi kwekhabhoni kunye neeshafti ze-spline, i-alloy cast iron camshafts kunye nezinye iindawo. , zifuna isantya esisezantsi sokucinywa kokupholisa, ngokufuthi kusetyenziswa ukuntywiliselwa ukupholisa emanzini okanye emanzini. Uninzi lwazo lunomsindo kwi-150 ~ 250 ℃, kwaye ixesha liyi-45 ~ 120min. Isetyenziselwa kakhulu ukuthambisa ii-workpieces ezinobungakanani obuncinci, imilo entsonkothileyo, udonga olucekethekileyo kunye nongqimba oluqinileyo olungenzulu ukuqinisekisa ukuqina okuphezulu kunye nokumelana nokunxiba komphezulu wamalungu. Funa.
③Ukuzifudumeza Yeka ukupholisa emva kokutshiza okanye ukucwiliswa kokupholisa, kwaye usebenzise ubushushu obukhoyo ngaphakathi kwendawo yokusebenza ecinyiweyo emva kokucima ukwenza indawo yokucima inyukele kubushushu obuthile kwakhona ukuhlangabezana neemfuno zokuthoba, kwaye ubushushu bayo kufuneka bube phezulu kunobushushu obupholileyo. eziko. Ngokuqhelekileyo, umgangatho wangaphakathi wamacandelo unobushushu obuphezulu emva kokupholisa imizuzwana emi-3 ukuya kwe-10. Njengexesha lokuzibamba, iindawo ezinkulu ziyi-6 kwaye ezincinci ziyi-40s ukugqiba ukuzibamba.
