Uhlalutyo lwenkqubo yokunyanga ubushushu bentsimbi spring chuck usebenzisa izixhobo zokucima rhoqo

I-spring chuck isetyenziswa ngokubanzi ekujikeni nasekuveliseni amakhonkco okuzala. Iringi ibekwe ngokwandiswa kwayo kunye nokuqina kwayo, kwaye kufuneka ibe neplastiki elungileyo kunye nokuqina. Ukuze kuququzelelwe imveliso kunye nolawulo, amashishini okuthwala ngokuqhelekileyo awasebenzisi intsimbi yasentwasahlobo, kwaye ahlala esebenzisa i-GCr15 yensimbi endaweni. Ngenxa yokuba i-GCr15 insimbi ayinayo iplastiki efanelekileyo kunye nokuqina, ihlala ibangela inani elikhulu leengqungquthela eziphukileyo kwimveliso, echaphazela imveliso eqhelekileyo. Imowudi yokungaphumeleli kwe-GCr15 yeentsimbi zentsimbi kukwaphuka kwangethuba, kwaye inxalenye yokwaphuka ikakhulu yintamo. , ngoko ke, kufuneka ukuba ube nobunzima obuphezulu kunye nokumelana nokugqoka, iplastiki ephezulu. Ukunyangwa kobushushu bokungeniswa kwezixhobo zokucima amaza aphezulu kunokuhlangabezana ngokupheleleyo neemfuno ze-collet chuck.

1) Inkqubo yonyango lobushushu lokungeniswa GCr15 intsimbi spring imilinganiselo chuck: intloko ubukhulu 60mm, umsila ububanzi 52mm, iyonke ubude 60mm. I-oven-frequency quenching furnace isetyenziselwa ukufudumeza unyango lobushushu kwi-500-550 °C, kwaye emva koko unyango lobushushu kwi-845 °C. Ngethuba lokusebenza, intloko ishushu kuqala imizuzu emi-5, kwaye yonke into ishushu imizuzu eyi-10. Emva kokuba i-oyile yonke ipholile, idluliselwa kwi-280- Incubate kwi-nitrate kwi-300 ° C nge-90min, kunye ne-tender initrate kwi-160 ° C nge-2h.

I-2) Ubunzima be-GCr15 yentsimbi ye-spring collet emva kokucinywa kwesithando sokucima i-frequency quenching malunga ne-10HRC ephantsi kunokucima okuqhelekileyo, kodwa ubomi bayo benkonzo buyanda ngamaxesha angama-1-1.67.
