Inqubo yokubumba ye-powder metallurgy

I-powder metallurgy (I-powder metallurgy, okubizwa ngokuthi yi-PM) ubuchwepheshe be-metallurgical lapho i-metal powder (noma ingxube yensimbi yensimbi kanye ne-powder yensimbi kanye ne-powder engeyona insimbi) isetshenziswa njengento eluhlaza ukuze isebenze imikhiqizo yensimbi noma izinto zokwakha ngokwakhiwa, ngokona noma ukwakha okushisayo. Inqubo yokukhiqiza ye-powder metallurgy iyafana nenqubo yokukhiqiza yemikhiqizo ye-ceramic, ngakho-ke abantu bavame ukubiza i-powder metallurgy indlela "ye-cermet indlela".
Ngokuthuthuka okusheshayo kwazo zonke izindlela zokuphila, izidingo ezahlukahlukene ezifana ne-Lightweight kanye ne-Compact Design, izingxenye eziningi neziningi ziya ngokuya ziyinkimbinkimbi, zikhuthaza inqubo yokubumba ye-powder ukuze abhekane nezinselelo eziningi.
Ngokwanda kwenani le-PM, izidingo zenqubo nakanjani ziba nzima. Njengomishini obucayi kakhulu emugqeni wokukhiqiza we-powder metluggy ingxenye, i-powder eyakha i-hydraulic Cindezela inquma ikhwalithi ye-powder compact futhi ivimbela ukuthuthukiswa komkhakha we-powder metluurg eChina. . Ukucindezela kwe-powder ephakeme ephezulu kungumpuphu ukwakheka komkhiqizo we-hydraulic Cindezela osuselwa kubuchwepheshe be-electro-hydraulic ratio, kepha ubuchwepheshe bayo busesimweni esikhiyiwe.
Njengamanje, izitshalo zokukhiqiza ze-powder ezinkulu ze-powder zethukile zethule imishini esezingeni eliphezulu eyakha imishini nemigqa yokukhiqiza evela phesheya, kepha isingeniso sodwa asikwazi ukuxazulula inkinga ngokuyisisekelo. Ngakho-ke, ukuthuthukiswa okuzimele kwe-High-Tech Powder eyenziwe ngemishini kuyinto enkulu kakhulu yokuthuthuka embonini ye-powder.

Inqubo ye-powder metallurgy yakha inqubo
Ukwakha isinyathelo esibalulekile kwinqubo ye-powder metallurgy. Inhloso yokwakha ukukhiqiza i-compact ngesimo esithile, ubukhulu, ubungako namandla. Ukubumba kokucindezela kuyindlela eyisisekelo ebaluleke kakhulu.
Indlela yokuxhumanisa yokuguqula inenqubo elula, ukusebenza kahle kakhulu, futhi ilungele ukukhiqizwa okuzenzakalelayo. Kodwa-ke, ukusatshalaliswa kwengcindezi kwale ndlela akuyona umfaniswano, ukuze ubuningi bomzimba obuluhlaza bungafani, futhi ukuqhekeka kuthambekele kuye kwenzeka, okuholela ekubonakaleni kwemikhiqizo enephutha.
a. Ukufana kokusatshalaliswa kwe-compact: Ngoba umzimba we-powder ugeleza kuzo zonke izinkomba ngemuva kokugcizelelwa ekufeni, kubangela ingcindezi eseceleni ebheke odongeni lwabafeli. Ingcindezi eseceleni ibangela ukungezwani, okuzobangela ingcindezi enkulu yehle ekuqondeni ukuphakama kweCompact.
Izindlela zokuthuthuka: 1) Yehlisa ukungqubuzana, faka uwoyela wokuthambisa odongeni lwangaphakathi noma usebenzise isikhunta ngodonga lwangaphakathi olubushelelezi;
2) Ukucindezela kwezindlela ezimbili kusetshenziselwa ukwenza ngcono ukungalingani kokusatshalaliswa kobukhulu beziko eziluhlaza;
3) Zama ukunciphisa isilinganiso sobubanzi obuphezulu lapho uklama isikhunta.
b. Ubuqotho obudilizwayo
Izindlela zokwenza ngcono: Ngokwakheka, izingxenye kufanele zigweme ama-ncamashi, ajulile futhi ama-grooves amancanyana, imiphetho ebukhali, abaphathi abancane nabancane kanye nezinye izimo ngangokunokwenzeka.
Ukusuka kumaphuzu amabili angenhla, incazelo enzima yomthelela wesici esisodwa kwinqubo yokulawula yokubumba ngekhwalithi yomkhiqizo, kepha ngezicelo ezingokoqobo, izinto ezahlukahlukene ezinethonya zilandelana. Ngesikhathi senqubo yocwaningo, kutholakala ukuthi izici ezithinta ikhwalithi yomkhiqizo ngasikhathi sinye yilezi:
1. Ithonya lokwakha ingcindezi kwikhwalithi ye-billet: Amandla okucindezela anethonya eliqondile ekubuseni. I-Pressure Drop yengcindezi ekhona ibangela ukunxusa futhi ibheke ngesikhathi sokucindezela, futhi imifantu ikhona endaweni ebonakalayo ye-compact ngemuva kokuthola phansi.
2. Umphumela wokucindezela ijubane kwikhwalithi ye-compact: Ngesikhathi sokuhlangana kwe-powder, ijubane lokucindezela lithinta ukuphuma komoya kusuka kuma-pores phakathi kwamaporeya, bese kuthinta ngqo ukufana kobunzima obukhulu. Umehluko wobude obukhulu weCompact ukhulu. Kulula ukukhiqiza imifantu.
I-3. Ithonya lokubamba isikhathi kwikhwalithi ye-compact: Ngesikhathi senqubo yokucindezela, kufanele kube nesikhathi esifanele sokubamba ngaphansi kwengcindezi yokucindezela ephezulu, engakhulisa kakhulu ubuhle be-compact.

Imishini yokubumba okuzenzakalelayo okuzenzakalelayo okusha okusanda kuthuthukiswa yiChengdu Zhengxi Hydraulic Equipment CommorT Co, Ltd. yakhelwe njengemishini entsha yokuphayona yasekhaya ehlanganisa izinzuzo zokucindezela kwemishini kanye ne-CNC servo hydraulic.
Uhlobo lwethempulethi oluntantayo luhlanganisa isisekelo sokubumba semishini singalawula ngokuphumelelayo ukuguquguquka komkhiqizo kanye nezinga elifanele lomkhiqizo. Ngesisekelo sokwanelisa ukucindezela ingcindezi engaguquki, inqubo ehleliwe yokucindezela kwenqubo yokucindezela kwemishini iyangezwa, engakwazi kuphela ukusebenza njengomkhawulo kodwa futhi njengendlela yokucindezela ehleliwe. Ukuvikelwa okungqimba okubili kokucindezela nokucindezela kakhulu kuthuthukisa ukunemba komkhiqizo nokusebenza kahle kokukhiqiza.
