I-powder metallurgy?

Ukubumba umjovo we-powder metallurgywazalelwa eCalifornia, eU.SA ngo-1973, ebizwa ngokuthi iMIM. Kuwuhlobo olusha lwe-powder metallurgy ukubumba ubuchwepheshe obusungulwe ngokuhlanganisa ubuchwepheshe bokubumba umjovo wepulasitiki nensimu ye-powder metallurgy.Powder metallurgy iseduze nenqubo yokubumba ngomjovo nge-powder metallurgy technology, okokuqala i-powder esiqinile kanye ne-organic binder ehlangana ndawonye, ​​​​ngokusebenzisa izinga lokushisa eliphakeme elingu-150 degrees lokushisa plasticizing, umjovo isikhunta imbobo nge umjovo ukubumba imishini, aphinde aqiniswe i-billet ukususwa, bese usebenzisa indlela yokugcina billet, bese usebenzisa i-billet ukususwa. njenge-powder metallurgy, ukunemba ngezingxenye ze-sintering.

I-powder metallurgy compaction molding iwukusebenzisa i-powder ukugcwalisa isikhunta ngamandla adonsela phansi, ngokusebenzisa umshini wokucindezela i-extrusion molding.Ezimbonini ezisebenzayo ezisetshenziswayo yiyona esetshenziswa kakhulu, ukucindezela okubandayo kwensimbi evaliwe, ukucindezela okubandayo kwe-isostatic, ukucindezela okushisayo kwe-isostatic, ukucindezela kwezinga lokushisa kuyacindezela. Ukusetshenziswa kobuchwepheshe bensimbi ye-powder kudlula isidingo sokukhiqiza imikhiqizo ewumphumela ngezinqubo zokususa insimbi, ngaleyo ndlela kunciphisa izindleko zokukhiqiza.

Njengomkhiqizi ohamba phambili wengxenye yempushana, sihlinzeka ngezinhlobonhlobo zamagiya ensimbi ayimpuphu ne-sintered ukuze kusetshenziswe izinto ezimbalwa ezimbonini eziningi. Ukwenziwa kwamagiya ensimbi ane-sintered kungaletha izinselelo eziningi kubakhiqizi abajwayelekile. Amajiyometri egiya ayinkimbinkimbi ngokwemvelo, ngokuvamile adinga izinqubo zemishini yesibili ezidla isikhathi - okwengeza izindleko kumcako ophansi. Kukulo mkhakha lapho i-powder metallurgy ihamba phambili.

Ngokusetshenziswa kwamathuluzi okunembayo, ukucindezela okuphezulu kwamathoni, nokucwiliswa, amagiya angenziwa ngendlela yensimbi eyimpushana (PM), ukuze abe eduze nenetha noma umumo wenetha, odinga ukwenziwa kwemishini okuncane noma okungekho nhlobo, futhi ngezikhathi zomjikelezo ngokushesha okukhulu kunomshini.
Izinzuzo Zokusebenzisa i-PM inUkukhiqiza Amagiya
Ukusebenzisa i-PM ekwenzeni amagiya kunikeza izinzuzo eziningi ezihlanganisa ukubekezelelana okuqinile, amagiya e-PM agijimayo athule, kanye nomthamo wamavolumu aphezulu. Inzuzo eyinhloko yokusebenzisa insimbi eyimpuphu ekwenzeni amagiya ukusebenza kahle kwezindleko. Ikhono lokukhiqiza amagiya amaleveli amaningi ahlanganiswe nokucushwa kwangaphakathi kanye nezingxenye zokubekezelelana okuqinile aqeda noma anciphise isidingo sokusebenza okwengeziwe. Konke sekuhlangene kubangela isikhathi nemali elondolozelwe isicelo sakho.

Njengoba kuncane ukumosha, insimbi eyimpuphu iyinqubo eluhlaza ngenxa yokusetshenziswa kwayo kwamandla aphansi kanye nezinsalela ezincane, okuyenza yonge kakhulu kunomshini ojwayelekile noma ukusakaza. Ukukhetha okubalulekile kwamagiya ensimbi ayimpuphu kuvumela ukwenziwa kahle komsebenzi wengxenye ekusetshenzisweni kwayo okuhlosiwe ngokuhlukahluka okuncane enqubweni yokukhiqiza.
