Umshini Wokuthunga Wezindwangu Izesekeli Zomshini Wokufekethisa

Incazelo emfushane:


Imininingwane Yomkhiqizo

Amandla enkampani

Omaka bomkhiqizo

Amabhizinisi ahlobene ne-powder metallurgy asebenza kakhulu embonini yezimoto, ukukhiqizwa kwemishini, imboni yensimbi, i-aerospace, imboni yezempi, i-instrumentation, amathuluzi we-hardware, izinto zikagesi zasendlini kanye neminye imikhakha yokukhiqiza nokucwaninga izingxenye ezisele, izinto zokusetshenziswa ezihlobene, ukukhiqizwa kwempahla eyisizayo, konke izinhlobo zemishini yokulungisa impushana, ukukhiqizwa kwemishini yokucwilisa. Imikhiqizo ihlanganisa ama-bearing, amagiya, amathuluzi okusika i-carbide, ama-dies, imikhiqizo eshayisanayo nokunye. amanye amapheya amabhuleki adinga ukukhiqizwa ubuchwepheshe be-powder metallurgy.Eminyakeni yakamuva, izingxenye zezimoto ze-P/M seziphenduke imakethe enkulu kunazo zonke embonini ye-P/M e-China.Cishe u-50% wezingxenye zezimoto ziyizingxenye ze-P/M.

(1) Izicelo :(izimoto, izithuthuthu, imishini yendwangu, imishini yokuthunga yezimboni, amathuluzi kagesi, amathuluzi ehardware.Izinto zikagesi, imishini yokwakha, njll.) zonke izinhlobo zezingxenye zempushana yensimbi (isisekelo sensimbi yethusi).

Ngakho-ke.Kusukela emotweni, izingxenye zesithuthuthu kuzo zonke izingxenye zensimbi eyimpushana zibalwe ingxenye yokukhuphuka.Ungabona lokho.Igiya le-powder metallurgical lisesimweni sokuthuthuka ngokushesha kuzo zonke izingxenye zegolide eziyimpushana.Uma ngokuvumelana nezici ze-powder metallurgical izingxenye ezizohlukaniswa.Igiya liyingxenye yesakhiwo.Isamba esiphelele sezingxenye zesakhiwo kuzo zonke izingxenye ezisekelwe ensimbi sikhulu kakhulu kunezinye izingxenye.Izinhlobonhlobo kanye nokuphumayo kwegiya le-powder metallurgy kuyanda usuku nosuku, futhi ububanzi bokusebenza kwazo liya liba banzi.

Lokhu kungenxa yalokhu: 1) lapho igiya linemijiko engajwayelekile, i-eccentricity, ama-radial protrusions noma imigodi: lapho igiya linezimbobo ezingajwayelekile, okhiye, izinhlangothi eziyisicaba, ama-splines, izimbobo eziyisikwele, izimbobo ezicijile; imigodi kanye nemigodi yokujula okuhlukene ohlangothini lwe-axial.Izindlela zokusansimbi ze-powder zilula ukwenza futhi zidinga ukucutshungulwa ngomshini okuncane noma azikho nhlobo.Igiya elijwayelekile le-powder metallurgy elinenqubo yokukhiqiza i-powder metallurgy, lidinga izinyathelo ezinhlanu kuphela.Okungukuthi ukwakha i-sintering yokwelapha ukushisa ukuthambisa uwoyela wokucwiliswa.Umshini nokukhiqiza ngezinto zokusanhlamvu kanye nokukhanga.Ngemva kwemoto ngaphandle indilinga ngaphakathi kwesiyingi sobuso obubodwa noma obubili, umgodi wokugaya, ukhiye, igiya lokuhombisa, ukudonsa, ukushisisa, ukuthambisa kanye ezinye izinqubo eziyishumi.Ngakho-ke, lapho indlela ye-powder metallurgy isetshenziselwa ukukhiqiza.Ngenxa yesifundazwe somsebenzi, impahla, ukusebenza kahle kokukhiqiza okuphezulu, ukusetshenziswa kwemishini encane, ukonga amandla.Umkhiqizo weGearizindleko ze-ion zincishiswa kakhulu.2) lapho kwenziwa amagiya ngendlela ye-powder metallurgy.Izinga lokusebenzisa impahla lingafinyelela ngaphezu kwama-95%.Lokhu kungenxa yokuthi: I-A.Shape engase yakheke ngokuqondile ibe izingxenye eziqediwe: B.Noma yikuphi ukungcola kokuhlanganisa ngaphambi kokucwilisa .Ingakwazi ukucutshungulwa futhi isetshenziswe kabusha.Lokhu akunakwenzeka uma amagiya enziwa ngezinye izindlela zokwenza imishini.3) Ukuphindaphindeka kwegiya le-powder metallurgy kuhle kakhulu.Ngenxa yempushana;Igiya le-Taijin lakhiwa ngokucindezela isikhunta.Ngaphansi kwezimo ezijwayelekile zokusetshenziswa, isikhunta singacindezela amashumi ezinkulungwane kuya kumakhulu ezinkulungwane zamagiya ahlanganisiwe.Yenziwe ngomshini

Okokuqala, izinzuzo zenqubo ye-powder metallurgy

I-1, ingakwazi ukucubungula izinto ezikhethekile.Izindlela ze-Metal powder metallurgy zingakhiqiza izinsimbi eziphikisayo kanye nezinhlanganisela, ama-alloys angama-pseudo, nezinto ezimboza.

2, londoloza insimbi, nciphisa izindleko.Ngenxa yokuthi i-powder metallurgy ingacindezelwa kusayizi wokugcina wokuhlanganisa, asikho isidingo sokusebenzisa ukucubungula ngomshini.Ukulahlekelwa kwensimbi ekhiqizwa ngale ndlela kuyiphesenti elilodwa kuya kwangu-5 kuphela, uma kuqhathaniswa namaphesenti angu-80 ukucubungula okuvamile.

Ukuthuthukiswa kwemikhiqizo ye-powder metallurgy

I-1, izingxenye zesakhiwo ezisezingeni eliphakeme: i-powder metallurgy imele ingxubevange esekwe ku-iron, izothuthukiswa ibe umthamo omkhulu wemikhiqizo enembile, izingxenye ezisezingeni eliphakeme zesakhiwo.

I-2, ingxubevange yokusebenza okuphezulu: ukukhiqizwa kwe-powder metallurgy kunesakhiwo se-microstructure esifanayo, ukucubungula kunzima futhi kuminyene ngokuphelele ukusebenza okuphezulu kwe-alloy.

3, isigaba esixubile ingxubevange ekhethekile: i-powder metallurgy enenqubo yokuqina ethuthukisiwe ukuze kukhiqizwe ingxubevange evamile equkethe ukwakheka kwesigaba esixubile.

4, izingxenye eziyinhlanganisela: ukucubungula ifomu eliyingqayizivele nelingelona elijwayelekile noma ukwakheka kwezingxenye eziyinhlanganisela.

5. Ukulungiswa kwezinto zokuhlanzeka okuphezulu.Inqubo ye-powder metallurgy ekukhiqizeni izinto ezibonakalayo ayincibiliki into, ngeke ihlanganiswe nezinye izinto ezilethwa ukungcola, futhi i-sintering yenziwa ku-vacuum nokunciphisa umoya, ingesabi i-oxidation kanye ngeke kube khona ukungcoliswa kwempahla.Ngakho-ke, ukuhlanzeka komkhiqizo kuphakeme kakhulu.

6. Ukulunga kokusatshalaliswa kwezinto ezibonakalayo.Indlela ye-powder metallurgy ingaqinisekisa ukunemba nokufana kokubunjwa kwezinto ezibonakalayo ngesilinganiso.

I-7, ukukhiqizwa ngobuningi ukuze kuncishiswe izindleko.I-powder metallurgy ifaneleka ukukhiqizwa kwemikhiqizo enenani elikhulu lokubunjwa okufanayo, njengamagiya neminye imikhiqizo enezindleko eziphezulu, ezinganciphisa kakhulu izindleko zokukhiqiza.345
