Nzira ye kudzima kwepasi kwekuregerera

Iko kudzima kwepasirese kwekuumba inzira yekurapa yekupisa umo pamusoro peiyo workpiece inokurumidza kupisa kune iyo tembiricha yekudzimisa uye ndokukurumidza kutonhorera, kuitira kuti chete pamusoro pevhu paunogona kuwana chimiro chakadzimwa, nepo chikamu chepakati chichiri kuchengetedza chimiro ndisati ndadzima. Inowanzo shandiswa induction kupisa pamusoro kudzima uye murazvo kudziyisa pamusoro kudzima. Kuomarara kwepamusoro kunowanzo svikiro kabhoni simbi uye yepakati kabhoni chiwanikwa simbi kukanganwa.

Induction kuomesa inoshandisa chirevo chemagetsi emagetsi induction kukonzeresa rakakura eddy parizvino pamusoro peiyo workpiece kuburikidza nekuchinjanisa zvazvino, kuitira kuti pamusoro peiyo forging ikurumidze kupisa, nepo musimboti wacho usina kumbopisa.

Hunhu hwe induction kupisa pamusoro kudzima: mushure mekudzima, iyo martensite zviyo zvinonatswa, uye kuomarara kwepasi kuri 2 ~ 3HRC yakakwira kupfuura yakajairwa kudzima. Iyo yepamusoro dhayeti ine hombe yakasara yekumanikidza kusagadzikana, iyo inobatsira kugadzirisa kuneta simba; hazvisi nyore kuburitsa deformation uye oxidative decarburization; zviri nyore kuona michina uye otomatiki, uye inokodzera kugadzirwa kwemazhinji. Mushure mekudzoreredza kupisa uye kudzima, kuitira kuti udzikise kudzima kushushikana uye kudzikisa brittleness, zvinodikanwa kuita yakaderera tembiricha tempering pa170 ~ 200 ° C.

Moto unopisa pamusoro kudzimisa inzira iyo iyo pamusoro pekukanganwa inokasira kupisa kuchikamu chekuchinja tembiricha pamusoro pechikamu chekuchinja tembiricha uchishandisa murazvo (tembiricha yakakwira kunge 3100 ~ 3200 ° C) ichipisa neoioacetylene gasi, ichiteverwa nekudzima uye kutonhora .

Yakadzika-tembiricha tempering inoitwa nekukurumidza mushure mekudzima, kana kupisa kwemukati kwemukati kweiyo forging kunoshandiswa pakuzvidzora. Iyi nzira inogona kuwana kudzika kuomarara kwe2-6 mm, nemidziyo yakapusa uye nemutengo wakaderera, uye inokodzera kugadzirwa kweimwe-chidimbu kana diki-batch.
