Inqubo yokubumba yokucindezelwa kwe-powder metallurgy

I-powder metallurgy (I-powder metallurgy, ebizwa ngokuthi i-PM) ubuchwepheshe be-metallurgical lapho i-metal powder (noma ingxube ye-metal powder kanye ne-non-metal powder) isetshenziswa njengezinto zokusetshenziswa ukwakha imikhiqizo yensimbi noma izinto ngokusebenzisa ukwakheka, ukuthungwa noma ukwakheka okushisayo. Inqubo yokukhiqiza i-powder metallurgy ifana nenqubo yokukhiqiza imikhiqizo ye-ceramic, ngakho-ke abantu bavame ukubiza indlela ye-powder metallurgy ngokuthi “indlela ye-cermet”.
Ngokuthuthuka okusheshayo kwazo zonke izindlela zokuphila, izidingo ezahlukahlukene njengomklamo olula nowokuncane, izingxenye eziningi ziya ngokuya ziba nzima, okwenza inqubo yokubumba insimbi yempuphu ibhekane nezinselele eziningi.
Njengoba inani le-PM likhuphuka, izidingo zenqubo zizoqina kakhulu. Njengemishini ebaluleke kakhulu emgqeni wokukhiqiza izingxenye ze-powder metallurgy, umshini wokucindezela we-hydraulic owenza i-powder unquma ikhwalithi ye-powder compact futhi uvimbela ukuthuthukiswa komkhakha we-powder metallurgy eShayina. . Umshini wokucindezela we-powder osebenza kahle kakhulu uwumkhiqizo wokucindezela we-hydraulic owenza i-powder osekelwe kubuchwepheshe be-electro-hydraulic ratio, kodwa ubuchwepheshe bawo busesimweni sokukhiywa.
Njengamanje, izimboni ezinkulu zokukhiqiza i-powder metallurgy zethule imishini ethuthukisiwe yokwenza i-powder kanye nemigqa yokukhiqiza evela kwamanye amazwe, kodwa isingeniso sodwa asikwazi ukuxazulula inkinga ngokuyisisekelo. Ngakho-ke, ukuthuthukiswa okuzimele kwemishini yokwenza i-powder yobuchwepheshe obuphezulu nakho kuyindlela enkulu yokuthuthukiswa embonini ye-powder.

Inqubo yokwakha insimbi yempuphu
Ukwakha kuyisinyathelo esibalulekile enqubweni yokusansimbi yempuphu. Inhloso yokwakha ukukhiqiza i-compact enesimo esithile, usayizi, ubuningi kanye namandla. Ukwakha ngokucindezela kuyindlela eyisisekelo yokwakha.
Indlela yokubumba yokucindezela inenqubo elula, ukusebenza kahle okuphezulu, futhi ilungele ukukhiqizwa okuzenzakalelayo. Kodwa-ke, ukusatshalaliswa kwengcindezi kwale ndlela akufani, ngakho-ke ubuningi bomzimba oluhlaza abufani, futhi ukuqhekeka kungenzeka, okuholela ekubonakaleni kwemikhiqizo enephutha.
a. Ukufana kokusatshalaliswa kobuningi be-compact: Ngenxa yokuthi umzimba we-powder ugeleza kuzo zonke izinhlangothi ngemva kokucindezeleka ku-die, kubangela ingcindezi eseceleni eqondile odongeni lwe-die. Ingcindezi eseceleni ibangela ukungqubuzana, okuzobangela ukwehla okukhulu kwengcindezi ekuqondeni kokuphakama kwe-compact.
Izindlela zokuthuthukisa: 1) Nciphisa ukungqubuzana, faka uwoyela wokugcoba odongeni olungaphakathi noma sebenzisa isikhunta esinodonga olungaphakathi olubushelelezi;
2) Ukucindezela okubili kusetshenziselwa ukuthuthukisa ukungalingani kokusatshalaliswa kobuningi bezinto eziluhlaza;
3) Zama ukunciphisa isilinganiso sokuphakama nobubanzi lapho uklama isikhunta.
b. Ukuqina kokususa ukuqina: ngenxa yokwanda kokunwebeka kwesikhunta sowesifazane ngesikhathi senqubo yokucindezela, lapho ingcindezi isuswa, i-compact ivimbela ukunwebeka kwesikhunta sowesifazane, futhi i-compact icindezelwa yi-radial, okwenza i-compact ithole ukucindezeleka kokususa ukuqina ngesikhathi senqubo yokususa. Ezinye izindawo ezibuthakathaka ku-compact zingabhujiswa ngaphansi kokucindezeleka kokususa okushiwo ngenhla.
Izindlela zokuthuthukisa: Ngokuphathelene nesakhiwo, izingxenye kufanele zigweme imisele emincane, ejulile nencane, imiphetho ebukhali, ama-boss amancane namancane kanye nezinye izimo ngangokunokwenzeka.
Kusukela kumaphuzu amabili angenhla, incazelo emfushane yomthelela wesici esisodwa enqubweni yokulawula ukubumba ekhwalithini yomkhiqizo, kodwa ekusetshenzisweni okungokoqobo, izici ezahlukahlukene ezithonya ziyahambisana. Ngesikhathi senqubo yocwaningo, kutholakale ukuthi izici ezithinta ikhwalithi yomkhiqizo ngesikhathi esisodwa yilezi:
1. Ithonya lokwakha ingcindezi ekhwalithini ye-billet: amandla okucindezela anethonya eliqondile ekuxineni. Ukwehla kwengcindezi okukhona kubangela ukuhlukanisa nokuxebuka ngesikhathi sokucindezela, futhi kuba nemifantu endaweni ehlanganayo ye-compact ngemva kokukhipha.
2. Umphumela wesivinini sokucindezela ekhwalithini ye-compact: Ngesikhathi sokucindezela i-powder, isivinini sokucindezela sithinta ukuphuma komoya kusuka ezimbotsheni eziphakathi kwama-powder, futhi sithinta ngqo ukufana kokuqina kwe-compact. Umehluko wobuningi be-compact mkhulu kakhulu. Kulula kakhulu ukukhiqiza imifantu.
3. Ithonya lesikhathi sokubamba ikhwalithi ye-compact: Ngesikhathi senqubo yokucindezela, kumele kube nesikhathi esifanele sokubamba ngaphansi kwengcindezi ephezulu yokucindezela, okungakhulisa kakhulu ubuningi be-compact.

Imishini yokubumba i-powder metallurgy ezenzakalelayo ngokuphelele esanda kuthuthukiswa yiChengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd. yakhelwe njengemishini entsha yasekhaya ehlanganisa izinzuzo zemishini yokunyathelisa kanye nemishini yokunyathelisa ye-CNC servo hydraulic.
Isisekelo sesikhunta esihlanganisiwe sohlobo lwethempulethi elintantayo semishini singalawula ngempumelelo ukuvumelana komkhiqizo kanye nesilinganiso esifanelekile somkhiqizo. Ngokusekelwe ekwaneliseni ukucindezela okuqhubekayo kwengcindezi, indlela yokucindezela inqubo eqondile yokucindezela kwemishini iyangezwa, engeke isebenze njengomkhawulo kuphela kodwa futhi njengendlela yokucindezela eqondile. Ukuvikelwa kokucindezela nokucindezela okuphindwe kabili kuthuthukisa kakhulu ukunemba komkhiqizo kanye nokusebenza kahle kokukhiqiza.
