Yintoni iteknoloji yomgubo wesinyithi?

Ubuchwephesha besinyithi somgubo baqala ukusetyenziswa e-United States ngo-1870. Yasebenzisa umgubo wesinyithi njengento ekrwada, yaza yacinezela iibheringi zengxubevange yobhedu ukuqaphela iteknoloji yokuzithambisa yokuthwala, kwaye yavelisa iindawo ezahlukeneyo kunye namacandelo ngokucinezela. kunye nokucula.Inkqubo yeteknoloji ye-powder metallurgy ivakala ingaqhelekanga kumntu wonke, kodwa ukuba emva kwengcaciso yam, kuya kuba lula ukuba uqonde.

Inkqubo esisiseko yeteknoloji ye-powder metallurgy
Izinto eziphambili ziyi-powder yentsimbi, emva koko i-powder yongezwa kwi-mold efunekayo, kwaye ke imodeli yenziwe yi (injection) okanye ingcinezelo, kwaye ekugqibeleni inxalenye efunwayo kunye nesiphumo sinokufumaneka nge-sintering.Ezinye iindawo zifuna ukusetyenzwa.

Nguwuphi umahluko weMIM kunye nePM yomgubo wentsimbi?
1: Ukubumba inaliti ye-powder metallurgy
Ukubumba inaliti yesinyithi yomgubo yazalwa eCalifornia ngo-1973, ebizwa ngokuba yiMIM.Luhlobo olutsha lwetekhnoloji yokubumba isinyithi somgubo esenziwe ngokudibanisa iteknoloji yokubumba inaliti yeplastiki kunye nentsimi yomgubo wesinyithi.Inkqubo yokubumba inaliti yesinyithi yomgubo isondele kakhulu kwitekhnoloji yomgubo wesinyithi.Okokuqala, i-powder eqinile kunye ne-binder yezinto eziphilayo zixutywe ngokufanayo, kwaye emva koko zifudumeze kwaye zenziwe ngeplastiki kwiqondo lokushisa eliphezulu le-150 degrees.Isixhobo sokubumba isitofu sisetyenziselwa ukufaka isikhunta kwi-cavity, kwaye emva koko siqinise kwaye simise.Indlela yokubola isusa isibophelelo kwindawo engenanto, kwaye ekugqibeleni, njengomgubo wesinyithi, iindawo ezichanekileyo ziveliswa ngokuntywila.

2: Uxinzelelo lwe-powder metallurgy
Ukubumba ukunyanzeliswa kwe-metallurgy kukugcwalisa ukubumba ngomgubo ngokuxhuzula, kwaye uyikhuphe ngoxinzelelo lomatshini.Yenye yezona zisetyenziswa kakhulu kwizicelo ezisebenzayo kwimizi-mveliso.Ukucinezela ukungunda kwentsimbi etywiniweyo ebandayo, ukucinezela okubandayo kwe-isostatic, ukucinezela okushushu kwe-isostatic, kunye noxinzelelo olufudumeleyo zonke zenza ucinezelo.Nangona kunjalo, ngenxa yokuba inokucinezelwa kuphela phezulu kwaye iphantsi kumacala omabini, ezinye iindawo eziyinkimbinkimbi zesakhiwo azikwazi ukuveliswa okanye zingenziwa kuphela zibe zingenanto.

Amalungu amaninzi asebenzisa isitofu sokubumba okanye ukubumba ukunyanzeliswa, kwaye inxalenye yokugqibela yokusebenza iya kwahluka.Ukuba awukakwazi ukwahlula kakuhle, ungathandabuzi ukuqhagamshelana nathi Jingshi New Materials ukuze ubonisane.
