Powder metallurgy giya uye zvigadzirwa zvakagadziridzwa, zvinoenderana neyakasiyana mashandiro echigadzirwa zvinodiwa, zvakafanana neyakajairika kupisa kupisa.Mushure mekudziya kwekudziya uye kudzima, ivo vanofanirwa kudzikamiswa kuti vaderedze kushushikana kwemukati uye kudzima brittleness, kudzikamisa chimiro, uye kuzadzisa inodiwa michina zvivakwa.Low tembiricha tempering inowanzoitwa.Mhando nhatu dzekupinza kupisa, kudziya kwechoto uye kuzvidzora zvinowanzo shandiswa mukugadzira.
①Induction tempering Iyo yakadzimwa workpiece inodziya zvakare inductively kupisa kuzadzisa chinangwa chekudziya, ndiko kuti, mushure mekuti workpiece yapiswa neinductor uye yakapfapfaidza-yakatonhorera, induction kupisa uye kupisa kunofanira kuitwa nekukurumidza.Nekuda kwenguva pfupi yekudziya, iyo microstructure ine yakakura kupararira.Inogona kuwana kukwirira kupfeka kusagadzikana uye kusimba kwakanyanya, nezvimwewo. Inonyanya kukodzera kudzikamisa shafts, maoko uye zvimwe zvikamu zvinogara zvichipisa nekudzimwa.
②Kupisa muchoto Chishandiso chinodziya muchoto chegomba, mafuta emafuta kana zvimwe midziyo mushure mekudzima kwepamusoro-frequency.Kupisa kwekushisa kunofanirwa kutariswa zvinoenderana nekuoma kunodiwa uye kuita, uye tembiricha yekudziya uye Nguva, seyakakwira kabhoni simbi maturusi uye yekuyeresa maturusi, yepakati kabhoni simbi kana yepakati kabhoni alloy simbi magiya uye spline shafts, alloy cast iron camshafts nezvimwe zvikamu. , inoda kutonhora kwakadzika kwekudzima, kazhinji kushandisa kunyudza kutonhora mumvura kana mumvura.Vazhinji vavo vari kushatirwa pa150 ~ 250 ℃, uye nguva yacho inowanzoita 45 ~ 120min.Inonyanya kushandiswa kudzikamisa maworkpieces ane saizi diki, chimiro chakaomarara, madziro akaonda uye asina kudzika akaomeswa dhizaini kuti ive nechokwadi chekuoma kwakanyanya uye kupfeka kuramba kwepamusoro pezvikamu.Zvinoda.
③Kuzvidzora Rega kutonhora mushure mekupfapfaidza kana kunyudzwa kutonhora, uye shandisa kupisa kuripo mukati memudziyo wakadzimwa mushure mekudzima kuita kuti nzvimbo yekudzima ikwire kune imwe tembiricha zvakare kuti isangane nezvinodiwa zvekudziya, uye tembiricha yaro inofanirwa kunge yakakwira kupfuura tembiricha yekudziya. muchoto.Kazhinji, mukati mezvikamu zvine tembiricha yepamusoro mushure mekutonhora kwemasekonzi matatu kusvika gumi.Senguva yekuzvidzora, zvikamu zvikuru zvitanhatu uye zviduku zviri makumi mana kuti upedze kuzvidzora.
