Izixhobo ezikhawulezayo zokucima izixhobo indlela yokufudumala

Izixhobo zokucima i-high-frequency quenching zisebenzisa umphumo wesikhumba, oko kukuthi, iteknoloji yokufudumala kwe-induction, ukunyusa ngokukhawuleza ukushisa kwendawo yokusebenza, kunye nokushisa kwendawo yokusebenza kunokunyuka ukuya kwi-800-1000 ° C ngemizuzwana embalwa. Ngophuhliso lweshishini, itekhnoloji yokufudumeza yokufudumeza yezixhobo zokucima isantya esiphezulu iye yaphuculwa ngokuqhubekayo, kwaye isicelo siye sandiswa ngokuqhubekayo. Emva kokuba i-workpiece igqitywe ngezixhobo zokucima i-high-frequency quenching, kufuneka ihlanjululwe ngexesha lokunciphisa i-brittleness yendawo yenguqu yokucima, ukuphelisa uxinzelelo lwangaphakathi emva kokucima, ukuphucula iplastiki kunye nokuqina, kunye nokufezekisa iimpawu ezifunekayo zomatshini. Ubunzima be-workpiece emva kokucima i-high-frequency quenching iphezulu kunokucima okuqhelekileyo, kwaye ukuqina kwakhona kulula ukuhla emva kokuvutha. Umhleli ulandelayo wazisa iindlela ezintathu eziqhele ukusetyenziswa apha:

1. Ukufudumala ezikweni:

I-furnace tempering yeyona ndlela ixhaphakileyo yokufudumala, kwaye ifanelekile kubukhulu obahlukeneyo bezinto zokusebenza. Ngokuqhelekileyo kubanjiswa kwiziko lomngxuma elinefeni. Ubushushu bokufudumala kufuneka bumiselwe ngokwezinto eziphathekayo zomsebenzi, ukuqina emva kokucima kunye nobunzima obufunekayo. Ngokuqhelekileyo, ubushushu bobushushu bentsimbi ye-alloy buphezulu kunolo lwentsimbi ye-carbon; ukuqina emva kokucima kuphantsi, kwaye ubushushu bokufudumala kufuneka buthotywe ngokufanelekileyo.

2. Ukucaphuka:

Oku kubizwa ngokuba yi-self-tempering kukulawula ixesha lokupholisa lokucima ukufakwa kwezixhobo zokucima i-high-frequency quenching, ukwenzela ukuba umphezulu we-workpiece ucinywe kodwa ungabandi. Ukushisa okushiyekileyo kwindawo yokucima ngokukhawuleza kudluliselwe kumphezulu ocinyiweyo we-workpiece kwaye ufikelele kubushushu obuthile ukwenza umphezulu ocinyiweyo. Ukutshintsha kobushushu bomphezulu we-induction lukhuni izixhobo zokusebenza ngexesha lokuzibamba. Ukuzibamba kukulungele ukufudumeza kwangaxeshanye kunye nokucima i-workpieces kunye nemilo elula.

3. Ubushushu bokufunda:

I-induction tempering Emva kokuqina kwe-induction of shafts emide kunye nemikhono, ukufudumala kwe-induction ngamanye amaxesha kusetyenziswa. I-induction tempering idla ngokudityaniswa nokuqiniswa kwe-induction ukwenza umbhobho wonyango lokufudumeza ubushushu. Emva kokuba i-workpiece ifudunyezwe yi-inductor yokucima kwaye ipholile ngendandatho yokutshiza amanzi, iqhutywe ngokuqhubekayo yi-inductor yokufudumala yokufudumala.

Xa kuthelekiswa nokufudumala kwisithando somlilo, i-induction tempering inexesha elifutshane lokufudumeza kunye nesantya sokufudumala ngokukhawuleza. Isiphumo sisimo se-microstructure esinentlukwano enkulu. Ukumelana nokunxiba kunye nokuqina kwempembelelo emva kobushushu kungcono kunezo zobushushu eziko. Umlilo uphezulu.
