Yiziphi izesekeli ezifanele ubuchwepheshe bokubumba umjovo we-metal powder?

1.Iyini ubuchwepheshe bokubumba umjovo we-metal powder?

 

Emhlabeni wei-powder metallurgy,ukubumba kwe-metal powder injection (MIM) luhlobo lobuchwepheshe bokubumba obuseduze. Izinqubo eziyisithupha zakha inqubo ye-MIM: ukukhiqiza impushana, ukuyihlanganisa ne-binder, ukubumba umjovo, ukwengeza i-ejenti yokususa amafutha ne-debinding, i-sintering kanye nokwelapha, nokuqeda.

 

Imininingwane imi kanje: Ukukhiqiza kwe-MIM kudinga usayizi wezinhlayiyana zensimbi encane kakhulu, ngokuvamile ebangeni lama-microns angu-0 kuye kwangama-30, ngendlela ye-ultra-high high water atomization noma indlela ye-gas atomization; I-powder ehlanganisiwe ne-binder: i-powder yensimbi kanye ne-organic binder ixubene ngokugcwele ibe yizinhlayiya, futhi izinhlayiya zengxube zishiswa zibe yisimo sepulasitiki; Ukubumba umjovo: ngokusebenzisa umshini wokubumba umjovo ukuze ucindezele ingxube emgodini wokubunjwa, wenze izingxenye zesiqalo esingenalutho; I-Degreasing binder: ngamakhemikhali noma indlela yokubola okushisayo ukususa i-binder ezingxenyeni ze-billet, ukuthola insimbi kuphela noma izingxenye ezincane ezisele ze-billet; I-Sintering kanye nokwelapha: izingxenye zithunyelwa esithandweni somlilo ukuze zelashwe ukuze kuqhutshekwe nokususa isibopho esisele; Ngemuva kokwelashwa: ngokucisha ukwelashwa kokushisa, ukwelashwa kokushisa kwamakhemikhali, ukwelashwa kwe-steam nezinye izindlela zokunciphisa izimbotshana zangaphakathi zezingxenye, ukuthuthukisa ukuminyana kwezingxenye, ukuthuthukisa amandla ezingxenye, ukumelana nokugqwala nokumelana nokugqoka, njll., ukwakha izingxenye zokugcina.

 

2, Yiziphi izesekeli ezifanele ubuchwepheshe bokubumba umjovo we-metal powder?

 

I-China MIM okwamanje isetshenziswa kakhulu emikhiqizweni eyahlukene, okuhlanganisa amawashi, izinto ezincane zezokwelapha, izinto zezemidlalo, izikhali ezilula, nezinye izinto. Ubuchwepheshe be-MIM, obungobunye bobuchwepheshe obuhambisanayo emishinini yendabuko, bungasebenzisa izinto zokwakha futhi benze imikhiqizo enezakhiwo eziyinkimbinkimbi ngempumelelo kakhulu kunomshini wendabuko.

 

Ukucubungula okusebenzayo kubuchwepheshe be-MIM kungahlukaniswa ngezimo ezilandelayo:

 

I-1, ohlelweni lwendabuko lokusika noma lokugaya, ukulahlekelwa kwezinto ezibonakalayo kukhulu kakhulu, futhi isikhathi sokucubungula siyizingxenye ezinde, ezifanele ubuchwepheshe be-MIM ukunciphisa izindleko.

 

I-2, i-MIM ingaba ukukhiqizwa ngobuningi, ukuhlangabezana nezimo ezithile zokukhiqiza ngobuningi, kodwa isidingo siphansi kunezindleko zezingxenye zokuvula isikhunta ezifanele ubuchwepheshe be-MIM.

 

3. Ezinsimbi okunzima ukuzisika, njenge-titanium ne-nickel alloy, ubuchwepheshe be-MIM bungacatshangelwa ukukhiqiza. Ukunemba kwemikhiqizo kuzothuthukiswa uma kuqhathaniswa nokucutshungulwa kwendabuko, futhi izinto zokwakha zizolondolozwa kakhulu.

 

I-4, enesimo sejometri esiyinkimbinkimbi, njengentambo engaphezulu, i-klooping, i-cross passage nezinye izingxenye, izingxenye ezinjalo ku-metallurgy ye-powder yendabuko kunzima ukuyifinyelela, enkambweni yokusika idinga ukushintsha isiteshi sokucubungula sezingxenye ze-axis eziningi noma izingxenye eziningi zereferensi, ezifanele ukucubungula ubuchwepheshe be-MIM.

 

5. Izingxenye ezidinga ukucutshungulwa ngenhlanganisela yezinto ezihlukene, njengezingxenye ezicutshungulwa ngenhlanganisela yezinto zensimbi neze-ceramic, noma izingxenye ezibekwe phezulu ngezinto ezihlukene, njengezizibuthe ezinzima - kazibuthe ezithambile, zikazibuthe - ezingezona kazibuthe, izinto ezibambayo - ezivikelayo.

 

3, Yiziphi izinto ezilungele ubuchwepheshe bokubumba umjovo we-metal powder?

 

Ubuchwepheshe be-MIM busebenza ezinhlobonhlobo zezinto ezisetshenziswayo. Eqinisweni, inqobo nje uma indawo yokuncibilika ingaphezu kwezinga lokushisa le-sintering, izinto ze-powder zingenziwa izingxenye ngobuchwepheshe be-MIM. Uma kucatshangelwa umnotho, izinto ezisetshenziswa kakhulu njengamanje zifaka i-iron base, isisekelo se-nickel, i-alloy ephansi, i-hard alloy, njll. UJIEHUANG CHIYANG njengoUmkhiqizi wezingxenye ze-MIMinikeza izinto zensimbi eyinsimbi eyinsimbi ne-nickel-based alloy powder yokubumba umjovo wensimbi oyimpushana, enezinkomba zokusebenza kwempahla ezifinyelela ezingeni eliphezulu lemboni.
