Ukubumba impushana kuvame ukusho indlela yenqubo yokubumba yokubumba ibe yingxenye yefa elivaliwe ngemva kokushisisa i-powder sintered preform.Kuyinqubo entsha ehlanganisa i-powder metallurgy yendabuko kanye nokuqamba ngokunemba, futhi ihlanganisa izinzuzo zakho kokubili.

2. Izici zenqubo Impushana efojiwe engenalutho iwumzimba osikiwe noma into engenalutho ekhishwe, noma okungenalutho okutholwe ngokucindezela okushisayo kwe-isostatic.Uma kuqhathaniswa nokufoja ngamabhilidi ajwayelekile, ukubumba ngempushana kunezinzuzo ezilandelayo:

1. Ukusetshenziswa okuphezulu kwempahla

I-Forging iwukuqamba ukufa okuvaliwe, akukho flash, akukho ukulahlekelwa kwezinto ezibonakalayo, kanye ne-margin encane yomshini olandelayo.Kusukela ku-powder eluhlaza kuya ezingxenyeni eziqediwe, inani eliphelele lokusebenzisa impahla lingafinyelela ngaphezu kwama-90%.

2. Ukusebenza okuphezulu kokubumba

Izinsimbi noma ama-alloys ngokuvamile abhekwa njengengalibaleki angenziwa.Isibonelo, ama-alloys okushisa okushisa okunzima ukuwashintsha angenziwa ngemikhiqizo enobumo obuyinkimbinkimbi ngokusebenzisa i-powder forging, futhi ama-forging anobunjwa obuyinkimbinkimbi angatholakala kalula.

3. Ukusebenza okuphezulu kokuqamba

I-powder forging preform iyashisiswa ngaphandle kokuvikelwa kwe-oxidation, futhi ukunemba nobulukhuni ngemuva kokubumba kungafinyelela izinga lokunemba kwe-die forging kanye nokusakazwa okunembayo.Umumo olungile we-preform ungasetshenziswa ukwenza ama-forging ayinkimbinkimbi esimweni sokugcina.
