Zeziphi izincedisi ezifanelekileyo kwitekhnoloji yokubumba inaliti yomgubo wesinyithi?

1.Yintoni iteknoloji yokubumba i-powder powder?

 

Ehlabathini leumgubo wesinyithi, ukubumba inaliti yomgubo wesinyithi (MIM) luhlobo lweteknoloji yokubumba ekufutshane.Iinkqubo ezintandathu zenza inkqubo ye-MIM: ukuvelisa umgubo, ukudibanisa kunye ne-binder, ukubunjwa kwenaliti, ukongeza i-degreasing kunye ne-agent agent, ukuthambisa kunye nokunyanga, kunye nokugqiba.

 

Iinkcukacha zimi ngolu hlobo lulandelayo: I-MIM yokuvelisa idinga ubungakanani bentsimbi encinci kakhulu ye-powder, ngokubanzi kuluhlu lwe-0 ukuya kwi-30 microns, nge-ultra-high high pressure water atomization method or gas atomization method;I-powder exutywe kunye ne-binder: i-powder yensimbi kunye ne-organic binder ixutywe ngokupheleleyo kwiinqununu, kwaye i-particle particles ishushu kwi-plasticized state;Isitofu sokubumba: ngomatshini wokubumba inaliti ukukhama umxube kwi-mold cavity, ukwenza iindawo zokuqala ezingenanto;I-binder ye-Degreasing: nge-chemical okanye i-thermal decomposition method yokususa i-binder kwiindawo ze-billet, ukufumana isinyithi kuphela okanye i-binder encinci ye-billet eseleyo;I-Sintering kunye nokunyanga: iinxalenye zithunyelwa kwisithando somlilo sokunyanga ukuze kususwe ngakumbi i-binder eseleyo;Emva konyango: ngokucima unyango lobushushu, unyango lobushushu bekhemikhali, unyango lomphunga kunye nezinye iindlela zokunciphisa i-pores yangaphakathi yamalungu, ukuphucula ukuxinana kwamalungu, ukuphucula ukomelela kwamalungu, ukuxhathisa ukubola kunye nokumelana nokunxiba, njl. iindawo zokugqibela.

 MIM SINTERED INDLELA

2, Zeziphi izincedisi ezifanelekileyo iteknoloji yokubumba inaliti yomgubo wesinyithi?

 

I-China MIM okwangoku isetyenziswa kakhulu kwiimveliso ezahlukeneyo, kubandakanya iiwotshi, izixhobo zonyango ezincinci, izixhobo zemidlalo, izixhobo ezilula, kunye nezinye izinto.Itekhnoloji ye-MIM, eyenye yetekhnoloji ehambelanayo esebenzayo kumatshini wemveli, inokusebenzisa imathiriyeli kwaye yenze iimveliso ezinezakhiwo ezintsonkothileyo ngempumelelo kunomatshini wemveli.

 

Ukusetyenzwa okusebenzayo kwitekhnoloji yeMIM kungahlelwa kwezi meko zilandelayo:

 

I-1, kwinkqubo yokusika okanye yokugaya yendabuko, ukulahlekelwa kwezinto eziphathekayo kukhulu kakhulu, kwaye ixesha lokucubungula lide kakhulu, lilungele iteknoloji yeMIM ukunciphisa iindleko.

 

I-2, i-MIM inokuvelisa ubuninzi, ihlangabezane neemeko ezithile zokuvelisa ubuninzi, kodwa imfuno iphantsi kuneendleko zeendawo zokuvula i-mold ezifanelekileyo kwi-teknoloji ye-MIM.

 

3. Ngezinyithi ekunzima ukuzisika, ezifana ne-titanium kunye ne-nickel alloy, iteknoloji ye-MIM inokuqwalaselwa kwimveliso.Ukuchaneka kweemveliso kuya kuphuculwa xa kuthelekiswa nokulungiswa kwendabuko, kwaye izinto ziya kugcinwa kakhulu.

 

I-4, enemilo yejometri enzima, efana nentambo yomhlaba, i-klooping, i-cross passage kunye nezinye iindawo, iindawo ezinjalo kwi-metallurgy ye-powder yendabuko kunzima ukuyifumana, kwinkqubo yokusika idinga ukutshintsha isikhululo sokulungisa i-multi-axis parts okanye ezininzi- iindawo zereferensi, zilungele ukusetyenzwa kobuchwephesha beMIM.

 

5. Amalungu adinga ukucutshungulwa ngokudityaniswa kwezinto ezahlukeneyo, njengamacandelo acutshungulwa ngokudityaniswa kwesinyithi kunye nemathiriyeli ye-ceramic, okanye iindawo ezibekwe ngaphezulu kwezinto ezahlukeneyo, ezifana nemagnethi enzima - imagnethi ethambileyo, imagnethi - non-magnetic, conductive. - izinto zokugquma.

 

3, Ziziphi izinto ezifanelekileyo kwiteknoloji yokubumba i-powder powder?

 

Itekhnoloji yeMIM isetyenziswa kuluhlu olubanzi ngokwentelekiso lwemathiriyeli.Ngokomgaqo, okoko nje indawo yokunyibilika ingaphezulu kobushushu be-sintering, izixhobo zomgubo zingenziwa iinxalenye ngeteknoloji ye-MIM.Ukuqwalasela uqoqosho, izinto ezisetyenziswa ngoku ngokuqhelekileyo ziquka isiseko sentsimbi, isiseko senickel, i-alloy ephantsi, i-alloy eqinile, njl njl. JIEHUANG CHIYANG njengeUmvelisi wamalungu e-MIMibonelela ngesinyithi kunye ne-nickel-based alloy metal powder izinto zokubumba inaliti yomgubo wesinyithi, kunye nezalathi zokusebenza eziphathekayo ezifikelela kwinqanaba eliphezulu loshishino.
