Inqubo yokwelapha ukushisa okuyimvamisa ephezulu yemimese yekhishi yensimbi engagqwali ecinywe imishini yokuqeda imvamisa ephezulu

Impahla yommese wekhishi wensimbi engagqwali ingu-3Cr13 noma 4Cr13, futhi ubukhulu bangaphandle bungu-180mmX80mmX2.5mm. Ngemuva kokugaya okuqinile ukuya ku-0.8-0.9mm, unqenqema lokusika lungaphansi kokwelashwa kokushisa kokungeniswa esithandweni sokucima imvamisa ephezulu. Ngemva kokucisha, ihlangabezana nezidingo ezilandelayo: ubulukhuni 50-56HRC, indawo eqinile ≥25mm, ukusabalalisa ubulukhuni obufanayo, nokuguqulwa ≤2mm.

1) Imingcele kagesi yedivayisi. I-voltage yokufaka ingu-380V, i-anode voltage ingu-7.5kV, i-anode current ingu-2.5A, i-voltage yethangi ingu-5kV, igridi yamanje ngu-0.6A, futhi imvamisa ingu-250kHz.

2) Ukucima inqubo yokushisa. I-high-frequency quenching furnace isetshenziselwa ukucisha. I-inductor ekhethekile kufanele yakhelwe. Ummese wekhishi kufanele ubekwe endaweni efanelekile ku-inductor. Isivinini sokushisisa sokungeniswa ngokuvamile singu-200-400 ℃/s. I-Austenitization iqedwa ngokuphazima kweso, futhi akukho ukugcinwa kokushisa okudingekayo. . Izinga lokushisa elicishayo liyi-1050-1100 ℃, kanti okokupholisa uwoyela. Ukushisa ku-200-220 ℃.

Ngaphakathi kobubanzi obungu-180mm X25mm endaweni eqinile, ubulukhuni ngemva kokucisha nokushisa bonke > 50HRC, futhi ukuqina kufana ngokuqhathaniswa. Zonke izinkomba zingahlangabezana nezidingo zobuchwepheshe.
