Insimbi yasentwasahlobo chuck isebenzisa imishini yokuqeda imvamisa ephezulu yokuhlaziywa kwenqubo yokwelashwa kokushisa

I-chuck yasentwasahlobo isetshenziswa kakhulu ekusetshenzisweni nasekukhiqizeni izindandatho zokuthwala. Kuyadingeka ukuba nobulukhuni obuhle bepulasitiki ukuthola iringi ngokukhulisa kwayo nokuqinisa komphumela. Ukuze kube lula ukukhiqizwa nokuphathwa, izinkampani ezithwalayo ngokuvamile azikhethi ukukhiqizwa kwensimbi yasentwasahlobo, futhi kaningi zisebenzisa insimbi ye-GCr15. Ngoba i-GCr15 steel ayinakho ukuqina okuhle kwepulasitiki, imvamisa kubangela ukuthi inani elikhulu lama-chucks entwasahlobo aqhekeze ngesikhathi sokukhiqiza, okuthinta ukukhiqizwa okujwayelekile. Imodi yokwehluleka kwe-GCr15 steel spring chucks ikakhulukazi ikwephuka kwasekuqaleni, kanti ingxenye yokuqhekeka ngokuyinhloko iyintamo Ngakho-ke, kuyadingeka ukuba kube nobulukhuni obuphakeme nokugqoka ukumelana, kanye ne-plasticity ephezulu. Ukwelashwa kokushisa kwe-induction usebenzisa imishini yokuqinisa imvamisa ephezulu kungahlangabezana ngokuphelele nezidingo zesiphephelo sentwasahlobo.

1) Inqubo yokwelashwa kokushisa kokungeniswa i-GCr15 steel spring chuck uhlaka lobukhulu: ikhanda ububanzi 60mm, ububanzi bomsila 52mm, ubude obuphelele 60mm. Sebenzisa isithando somlilo esivama imvamisa ephezulu ukwenza ukushisa kokushisa ngaphambi kokushisa ku-500-550 ℃, bese ukwelashwa ngokushisa ku-845 ℃. Ngesikhathi sokusebenza, fudumeza ikhanda kuqala ngo-5min, bese ulishisisa lonke ngo-10min, bese udlulisela ku-280- ngemuva kokuthi lonke selipholisiwe uwoyela. Gcina izinga lokushisa ku-nitrate ku-300 ℃ ngama-90min, bese ulaka i-nitrate ngo-160 ℃ x2h. Ku

1. Imiphumela yokuhlolwa nokuhlaziywa. Ithebula elilandelayo likhombisa ukuqhathaniswa kwemiphumela ye-GCr15 steel collet chucks ngemuva kwezinqubo ezimbili ezahlukene zokwelashwa kokushisa. Imiphumela yokuhlolwa ikhombisa ukuthi ubulukhuni be-GCr15 yensimbi chuck chuck ngemuva kokucima isithando somlilo esivama imvamisa ephezulu icishe ibe yi-10HRC ephansi kunaleyo yokucima okujwayelekile, kepha impilo yayo yenkonzo yanda ngama-1-1.67 times.
