Simbi chitubu chuck inotora yepamusoro-frequency kudzima michina yekupisa kurapwa maitiro

Iyo chitubu chuck inoshandiswa zvakanyanya mukugadzira uye kugadzirwa kwekutakura mhete. Izvo zvinodikanwa kuve neyakajeka epurasitiki kuomarara kuti uwane iyo mhete kuburikidza nekuwedzera kwayo uye kuomesa mhedzisiro. Kuti uite kugadzirwa uye manejimendi, makambani anotakura kazhinji haasarudze ekugadzira simbi simbi, uye anowanzo shandisa GCr15 simbi pachinzvimbo. Nekuti GCr15 simbi haina hurema hwepurasitiki, inowanzo kukonzera huwandu hwakawanda hwematsutso echinyakare kutsemuka panguva yekugadzira, izvo zvinokanganisa zvakajairika kugadzirwa. Iyo yekukundikana maitiro eGCr15 simbi chitubu chucks inonyanya kutanga kutsemuka, uye iyo yekutyora chikamu chiri kunyanya mutsipa Naizvozvo, zvinofanirwa kuve nehupamhi hwekuoma uye kupfeka kuramba, uye yakakwirira mapurasitiki. Induction kupisa kurapwa uchishandisa yakakwira-frequency kuomesa michina inogona kuzadzisa zvakakwana izvo zvinodikanwa zvechirimo chuck.

1) Induction kupisa kurapwa maitiro GCr15 simbi chitubu chuck rongedza zviyero: musoro dhayamita 60mm, muswe dhayamita 52mm, hurefu hwese 60mm. Shandisa yakakwira-frequency kudzima choto kuita preheating kupisa kurapwa pa500-550 ℃, uyezve kupisa kupisa pa845 ℃. Panguva yekushanda, tanga kupisa musoro kwe5min, wobva wapisa iyo yese ye10min, wozoendesa ku280- mushure mekunge iyo yose yatonhodzwa nemafuta. Chengetedza iyo tembiricha mu nitrate pa 300 ℃ kwe 90min, wozotsamwa ne nitrate pa 160 ℃ x2h. Ku

1. Mhedzisiro yekuedzwa uye kuongorora. Iyi tafura inotevera inoratidza kuenzaniswa kwemhedzisiro yeGCr15 simbi collet chucks mushure memaviri akasiyana maitiro ekurapa kupisa. Mhedzisiro yekuedzwa inoratidza kuti kuomarara kweiyo GCr15 simbi chitubu chuck mushure mekudzima mu-high-frequency quenching vira inenge 10HRC yakaderera pane yeyakajairika kudzima, asi hupenyu hwayo hwebasa hwakawedzerwa ne1-1.67 nguva.
