Imishini yokuqeda imvamisa ephezulu indlela yokuphefumula

Imishini yokucisha i-high-frequency quenching isebenzisa umphumela wesikhumba, okungukuthi, ubuchwepheshe bokushisa kwe-induction, ukwandisa ngokushesha izinga lokushisa elingaphezulu kwendawo yokusebenza, futhi izinga lokushisa elingaphezulu le-workpiece lingakhuphuka libe ngu-800-1000 ° C ngemizuzwana embalwa. Ngokuthuthuka kwemboni, ubuchwepheshe bokushisa lokungeniswa kwemishini yokucisha imvamisa ephezulu buye bathuthukiswa ngokuqhubekayo, futhi isicelo sibuye sanwetshwa ngokuqhubekayo. Ngemuva kokuthi i-workpiece icinywe imishini yokucisha i-high-frequency quenching, idinga ukuthukuthela ngesikhathi ukuze kuncishiswe i-brittleness ye-quenching transition zone, ukuqeda ukucindezeleka kwangaphakathi ngemva kokucisha, ukuthuthukisa i-plasticity kanye nokuqina, nokufeza izakhiwo ezidingekayo zemishini. Ukuqina kwe-workpiece emva kokucisha imvamisa ephezulu kuphakeme kunokokucisha okuvamile, futhi ukuqina nakho kulula ukuncipha ngemva kokushisa. Umhleli olandelayo wethula izindlela ezintathu ezivame ukusetshenziswa lapha:

1. Ukushisa esithandweni:

Ukushisa kwesithando somlilo kuyindlela ejwayelekile kakhulu yokushisa, futhi ifanele osayizi abahlukahlukene bezinto zokusebenza. Ngokuvamile kubaswa esithandweni somgodi esinefeni. Ukushisa kokushisa kufanele kunqunywe ngokusho kwempahla yokusebenza, ukuqina ngemva kokucisha kanye nobunzima obudingekayo. Ngokuvamile, izinga lokushisa elishisayo lensimbi ye-alloy liphakeme kunalelo le-carbon steel; ubulukhuni ngemva kokucinywa buphansi, futhi izinga lokushisa lokushisa kufanele lehliswe ngokufanelekile.

2. Ukuzithiba:

Okubizwa ngokuthi ukuzithukuthela ukulawula isikhathi sokupholisa sokucinywa kokungeniswa kwemishini yokucisha imvamisa ephezulu, ukuze ingaphezulu le-workpiece licime kodwa lingabandi. Ukushisa okusele endaweni yokucisha kudluliselwa ngokushesha endaweni ecishiwe ye-workpiece futhi kufinyelela izinga lokushisa elithile ukuze kwenziwe ungqimba olucinyiwe oluphezulu. Ukushintsha kwezinga lokushisa elingaphezulu le-induction lukhuni izingcezu zokusebenza ngesikhathi sokuzithiba. I-self-tempering ifaneleka ekushiseni ngesikhathi esisodwa kanye nokucisha ama-workpieces anezimo ezilula.

3. Ukushisa kokungeniswa:

Ukushisa kwe-induction Ngemuva kokuqina kokufakwa kwe-induction of shafts nemikhono emide, ukufudumala kwe-induction ngezinye izikhathi kuyasetshenziswa. Ukushisa kwe-induction kuvame ukufaniswa nokuqina kokungeniswa ukuze kwakhiwe ipayipi lokwelapha ukushisa lokungeniswa. Ngemuva kokuthi i-workpiece ishisiswe yi-inductor yokucisha futhi ipholiswe yindandatho yesifutho samanzi, iqhubeka ishiswa yi-inductor yokushisa ukuze ipholile.

Uma kuqhathaniswa nokushisa esithandweni, ukushisa kwe-induction kunesikhathi esifushane sokushisa kanye nesivinini sokushisa esisheshayo. Umphumela uba i-microstructure enokwehlukana okukhulu. Ukumelana nokugqokwa kanye nokuqina komthelela ngemuva kokushisa kungcono kunalezo zokufudumeza esithandweni. Umlilo uphezulu.
