Uhlalutyo lwenkqubo yokubuyisela isandla usebenzisa izixhobo ezikhawulezayo zokucima izixhobo kunyango lobushushu

Izihlambi zezandla zisebenzisa izixhobo zokucima ubushushu obuphezulu kunyango lobushushu. Kukho izinto ezininzi ezichaphazela umphumo wokushisa ukushisa, njengenkqubo yokunyanga ukushisa kunye nezinto eziluhlaza. Phakathi kwezi zinto, inkqubo yonyango lokushisa inefuthe elikhulu. Ngoko ke, kubaluleke kakhulu ukuba uqonde inkqubo yonyango lokushisa kwe-reamer yesandla.

1. Iimfuno zobugcisa zesixhasi sezandla:

Izinto ezisetyenziswa ngokuqhelekileyo kwi-rereamer yezandla yintsimbi ye-9SiCr.

Ubunzima: 62-64HRC ye-φ3-8; I-63-65HRC ye-φ8.

Ukubamba ubunzima: 30-45HRC.

Ubungakanani bokugoba ukugoba kwe-reamer yesandla kunqunywe ukuba yi-0.15-0.3mm ngokobubanzi kunye nobude.

2. Inkqubo yonyango lobushushu

Indlela yokulungiswa kobushushu yile: ukufudumeza, ukufudumeza, ukupholisa, ukulungisa, ukufudumala, ukucoca, ukuhlolwa kobunzima, ubumnyama, kunye nokuhlolwa kwembonakalo. Inkqubo yokufudumala iqhutyelwa kakhulu ngezixhobo zokucima i-high-frequency quenching, phakathi kwayo i-preheating ye-preheating yi-600-650 ° C, iqondo lokushisa liyi-850-870 ° C, kwaye iqondo lokushisa liyi-160 ° C.

Isixhobo sokubuyisela isandla sinokucinywa ngokupheleleyo kwaye emva koko sifakwe i-shank. Ubushushu be-annealing yi-600 ° C, kwaye emva koko bucinywe kwityuwa ye-nitrate kwi-150-180 ° C ukupholisa ngaphezu kwe-30s.

3. Inkcazo yenkqubo

(1) Ukuze kuncitshiswe ukugoba kwesixhobo sokuphinda sicime emva kokucinywa, i-anneal yokunciphisa uxinzelelo ingasetyenziswa ngaphambi kokucinywa.

(2) Ukuze kuncitshiswe ukuphambuka kwe-reamer kunye nobubanzi obungaphantsi kwe-13mm, umda ophantsi weqondo lokushisa lokucima unokuthathwa. Kumandla ehinge enobubanzi obungaphezulu kwe-13mm, ukuze kuphuculwe ukuqina kwayo, kunokusetyenziswa umda ophezulu wokucima ubushushu kunye nokupholisa kweoli eshushu.
