Imininingwane yomkhiqizo

Amathegi womkhiqizo

Amabhizinisi ahlobene nensimbi ye-Powder asebenza kakhulu embonini yezimoto, ukukhiqizwa kwemishini, imboni yensimbi, i-aerospace, imboni yezempi, izinsimbi, amathuluzi wehadiwe, izinto zasendlini ezisebenza ngogesi nezinye izinkambu zokukhiqizwa kwezingxenye zokungasebenzi kanye nocwaningo, izinto zokusetshenziswa ezihlobene, ukukhiqizwa kwezinto ezisizayo, konke izinhlobo zemishini yokulungiselela impuphu, okokukhiqiza imishini yokufaka izinto sintering.Imikhiqizo ifaka amabombo, amagiya, amathuluzi wokusika we-carbide, ifa, imikhiqizo yokushayisana nokunye.Amabhizinisi ezempi, izikhali ezisindayo nemishini, njengamagobolondo okubhoboza izikhali, ama-torpedoes, izindiza namathangi amanye amabhuleki amabhuleki adinga ukukhiqizwa nge-powder metallurgy technology. Eminyakeni edlule, izingxenye zezimoto ze-P / M seziyimakethe enkulu kunazo zonke embonini ye-P / M eChina. Cishe ama-50% wezingxenye ezizenzakalelayo izingxenye ze-P / M.

(1) Izicelo: (izimoto, izithuthuthu, imishini yendwangu, imishini yokuthunga yezimboni, amathuluzi kagesi, amathuluzi wehadiwe.Imishini kagesi, imishini yokwakha, njll.) Zonke izinhlobo ze-powder metallurgy (insimbi yethusi) izingxenye.

(2) ukuhlukaniswa: izinto ezisansimbi ze-powder metallurgy, izinto zensimbi ezilwa nokungqubuzana, i-powder metallurgy friction materials, i-powder metallurgy izingxenye zesakhiwo, i-powder metallurgy materials, ne-powder metallurgy izinto zikagesi kanye ne-powder metallurgy izinto zokushisa eziphakeme, njll.

Ngakho-ke, kusukela ezimotweni, izingxenye zesithuthuthu kuzo zonke izingxenye zensimbi yensimbi zibalwa ngokwesilinganiso sokukhuphuka.Ungabona ukuthi.Igiya le-metallurgical lisendaweni yokuthuthuka ngokushesha kuwo wonke amapayipi egolide e-metallurgical izingxenye.Uma ngokuya ngezici ze Izingxenye zokuhlukanisa.Igear ingeyengxenye yokwakheka.Umsindo ophelele wezingxenye zokwakhiwa kuzo zonke izingxenye ezisuselwe ensimbi mkhulu kakhulu kunezinye izingxenye.Ukuhluka nokukhishwa kwe-powder metallurgy gear kuyanda usuku nosuku, nobubanzi besicelo sazo iya ngokuya iba banzi.

Lokhu kungenxa yokuthi: 1) lapho igiya linamajika angajwayelekile, amandla e-eccentricity, ama-radial protrusions noma imigodi: lapho igiya linezimbobo ezingajwayelekile, okhiye, izinhlangothi eziyizicaba, ama-splines, izimbobo eziyisikwele, izimbobo ze-taper; Lapho igiya linama-protrusions, grooves, blind izimbobo nemigodi yokujula okuhlukile kusiqondiso se-axial.Izindlela zensimbi ye-powder kulula ukuzenza futhi zidinga ukucutshungulwa okungatheni noma okungekho okwenziwe ngomshini.Ijenali yensimbi yokusansimbi nge-powder inqubo yokukhiqiza insimbi, idinga kuphela izinyathelo ezinhlanu.Okuzakhela igama lokushiswa kokushisa ukushisa Ukwenza uwoyela wokucwiliswa Ukwenza ngomshini nokukhiqiza ngezinto zokusakaza nokufaka izinto zokwakha izinto ngemuva kwemoto ngaphandle kwendilinga ngaphakathi kwendilinga ubuso obunamapulangwe amabili noma amabili, indawo yokugaya emagebhugebhu, umgwaqo ongukhiye, igiya lokubamba, ukuphikisa, ukwelashwa kokushisa, ukufutheka kanye ezinye izinqubo eziyishumi.Ngakho-ke, lapho kusetshenziswa indlela yokusansimbi yokwenza impuphu.Ngenxa yesifundazwe sezabasebenzi, okokusebenza, ukusebenza kahle kokukhiqiza, ukusetshenziswa kwemishini emincane, ukonga ugesi. Izindleko ze-ion zehliswa kakhulu. 2) lapho wenza amagiya nge-powder metallurgy method.Isilinganiso sokusetshenziswa kwezinto ezibonakalayo singafinyelela ngaphezu kuka-95%. Lokhu kungenxa yokuthi: I-A.Sape engakhiwa ngqo ibe izingxenye eziqediwe: B. Noma ikuphi ukungcola kokuxina ngaphambi kokuhlwaya .Angashiswa futhi asetshenziswe kabusha.Lokhu akunakwenzeka uma amagiya enziwa ngezinye izindlela zokukhanda.3) Ukukhiqizwa kabusha kwe-powder metallurgy gear kuhle kakhulu.Ngenxa yempuphu; I-Taijin gear yakhiwa ngokucindezela kwesikhunta. Ngaphansi kwezimo ezijwayelekile zokusetshenziswa, isikhunta singacindezela amashumi ezinkulungwane kuya kumakhulu ezinkulungwane zama-compact egiya.Yenziwe ngemishini

Okokuqala, izinzuzo zenqubo ye-powder yokusansimbi

1, ingacubungula izinto ezikhethekile.Izinto ezisetshenziswayo ze-metallurgy powder zingakhiqiza izinsimbi ezikhanyayo kanye nezinhlanganisela, ama-alloys mbumbulu, nezinto zokwakha.

2, gcina insimbi, nciphisa izindleko.Ngenxa yokuthi i-powder metallurgy ingacindezelwa kusayizi wokugcina wokuminyaniswa, asikho isidingo sokusebenzisa ukucubungula okwenziwe ngomshini.Ukulahleka kwensimbi okukhiqizwe ngale ndlela kungamaphesenti ama-1 kuya kwama-5 kuphela, uma kuqhathaniswa namaphesenti angama-80 ukucubungula okujwayelekile.

Ukuthuthukiswa kwemikhiqizo yensimbi yokusansimbi

1, izingxenye ezisezingeni eliphakeme zokwakheka: i-powder metallurgy imele ingxubevange yensimbi, izothuthukiswa ibe ngumthamo omkhulu wemikhiqizo enembile, izingxenye ezisezingeni eliphakeme zesakhiwo.

2, ukusebenza okuphezulu kwengxubevange: i-powder metallurgy yokukhiqiza inesakhiwo esifanayo se-microstructure, ukucubungula kunzima futhi kuminyene ngokuphelele ukusebenza kwengxubevange ephezulu.

I-3, i-alloy ekhethekile yesigaba esixutshiwe: i-powder metallurgy enenqubo yokuqina yokuqina yokwakha ingxubevange ekhethekile equkethe ukwakheka kwesigaba esixubekile.

4, izingxenye ezihlanganisiwe: ukucubungula ifomu elihlukile nelingejwayelekile noma ukwakheka kwezingxenye ezihlanganisiwe.

5. Ukulungiswa kwezinto zokuhlanzeka okuphezulu.Inqubo yokusansimbi yomgogodla enqubweni yokukhiqiza impahla ayincibilikisi impahla, ngeke ixutshwe nezinye izinto ezilethwa ukungcola, futhi isintering yenziwa nge-vacuum futhi inciphise umoya, ingesabi i-oxidation futhi ngeke kube khona ukungcoliswa kwezinto.Ngakho-ke, ubumsulwa bomkhiqizo buphezulu kakhulu.

6. Ukulungiswa kokusatshalaliswa kwempahla.Indlela yokusansimbi yomgogodla ingaqinisekisa ukunemba nokufana kokwakheka kwento esilinganisweni.

I-7, ukukhiqizwa ngobuningi ukunciphisa izindleko.I-metallurgy yensimbi ilungele ukukhiqizwa kwemikhiqizo enenani elikhulu lomumo ofanayo, njengegiya neminye imikhiqizo enezindleko eziphakeme, ezinganciphisa kakhulu izindleko zokukhiqiza.
