Inqubo yokubumba yokucindezelwa kwe-powder metallurgy

I-powder metallurgy (I-Powder metallurgy, ebizwa ngokuthi yi-PM) ubuchwepheshe be-metallurgical lapho impushana yensimbi (noma ingxube yempushana yensimbi kanye nempushana engeyona eyensimbi) isetshenziswa njengempahla eluhlaza ukuze kwakhiwe imikhiqizo yensimbi noma izinto zokwakha ngokwenza, ukucwilisa noma ukwenza ukushisa.Inqubo yokukhiqiza i-powder metallurgy ifana nenqubo yokukhiqiza imikhiqizo ye-ceramic, ngakho-ke abantu bavame ukubiza indlela ye-powder metallurgy "indlela ye-cermet".
Ngokuthuthuka okusheshayo kwazo zonke izigaba zokuphila, izidingo ezihlukahlukene ezifana ne-lightweight kanye ne-compact design, izingxenye eziningi ziya ngokuya ziba yinkimbinkimbi, okwenza inqubo yokubumba i-powder metallurgy ibhekane nezinselele eziningi.
Ngokukhula kwenani le-PM, izidingo zenqubo nakanjani zizoqina.Njengemishini ebaluleke kakhulu emugqeni wokukhiqiza ingxenye ye-powder metallurgy, i-powder eyenza i-hydraulic press inquma ikhwalithi ye-powder compact futhi ivimbela ukuthuthukiswa kwemboni ye-powder metallurgy e-China..Umshini wokunyathelisa we-powder osebenza kahle kakhulu uyimpushana eyenza umkhiqizo wokucindezela we-hydraulic osuselwe kubuchwepheshe besilinganiso se-electro-hydraulic, kodwa ubuchwepheshe bawo busesimweni esikhiyiwe.
Njengamanje, izitshalo ezinkudlwana zokukhiqiza i-powder metallurgy zethule imishini yokwakha impushana ethuthukisiwe nemigqa yokukhiqiza evela phesheya, kodwa isingeniso sisodwa asikwazi ukuxazulula inkinga ngokuyisisekelo.Ngakho-ke, ukuthuthukiswa okuzimele kwemishini yokwenza impushana yobuchwepheshe obuphezulu kubuye kube umkhuba omkhulu wentuthuko embonini yempushana.

Inqubo yokwenza i-powder metallurgy
Ukwakha kuyisinyathelo esibalulekile enqubweni ye-powder metallurgy.Inhloso yokwenza ukukhiqiza inhlanganisela enomumo othize, usayizi, ukuminyana namandla.I-Compression molding iyindlela eyisisekelo kakhulu yokwakha.
Indlela yokubumba yokucindezela inenqubo elula, ukusebenza kahle okuphezulu, futhi ilungele ukukhiqizwa okuzenzakalelayo.Kodwa-ke, ukusatshalaliswa kwengcindezi yale ndlela akufani, ukuze ukuminyana komzimba oluhlaza kungafani, futhi ukuqhekeka kujwayele ukwenzeka, okuholela ekubukeni kwemikhiqizo enesici.
a.Ukufana kokusatshalaliswa kokuqina kwe-compact: Ngenxa yokuthi umzimba wempushana ugeleza kuzo zonke izinkomba ngemuva kokucindezelwa ku-die, kubangela ingcindezi eseceleni perpendicular odongeni lokufa.Ingcindezi eseceleni idala ukungqubuzana, okuzodala ukwehla kwengcindezi enkulu ekuqondeni kobude be-compact.
Izinyathelo zokuthuthukisa: 1) Nciphisa ukungqubuzana, sebenzisa amafutha okugcoba odongeni lwangaphakathi noma usebenzise isikhunta esinodonga lwangaphakathi olubushelelezi;
I-2) Ukucindezela kwezindlela ezimbili kusetshenziselwa ukuthuthukisa ukungalingani kokusatshalaliswa kokuqina kwama-compact aluhlaza;
3) Zama ukunciphisa isilinganiso sobude bobude lapho uklama isikhunta.
b.Ukwehlisa ubuqotho: ngenxa yokunwebeka kwesikhunta sesifazane ngesikhathi senqubo yokucindezela, lapho ukucindezela kususwa, i-compact ivimbela ukufinyela okunwebekayo kwesikhunta sowesifazane, futhi i-compact ingaphansi kwengcindezi ye-radial, okubangela ukuthi i-compact ithole i-shear reverse. ukucindezeleka phakathi nenqubo yokudiliza Ezinye izindawo ezibuthakathaka ku-compact zingase zibhujiswe ngaphansi kwengcindezi yokugunda eshiwo ngenhla.
Izinyathelo zokuthuthukisa: Mayelana nesakhiwo, izingxenye kufanele zigweme izindonga ezincane, ezijulile neziwumngcingo, imiphetho ebukhali, abaphathi abancane nabancane kanye nezinye izimo ngangokunokwenzeka.
Kusukela kulawa maphuzu amabili angenhla, incazelo enzima yomthelela wesici esisodwa kwinqubo yokulawula ukubumba kukhwalithi yomkhiqizo, kodwa ekusebenzeni okungokoqobo, izici ezihlukahlukene ezithonyayo ziyahambisana.Phakathi nenqubo yocwaningo, kutholakala ukuthi izici ezithinta ikhwalithi yomkhiqizo ngesikhathi esifanayo yilezi:
1. Umthelela wokwenza ingcindezi kwikhwalithi ye-billet: amandla okucindezela anethonya eliqondile ekugqineni.Ukwehla kwengcindezi okukhona kudala i-delamination kanye nokuxebuka ngesikhathi sokucindezela, futhi imifantu iba khona ekuxhumaneni kwe-compact ngemva kokudilizwa.
2. Umphumela wejubane lokucindezela kwikhwalithi ye-compact: Ngesikhathi sokuhlanganiswa kwe-powder, isivinini sokucindezela sithinta ukukhishwa komoya kusuka kuma-pores phakathi kwama-powders, futhi kuthinta ngokuqondile ukufana kwe-compact density.Umehluko wokuminyana we-compact mkhulu kakhulu.Kulula ukukhiqiza imifantu.
3. Ithonya lokubamba isikhathi kwikhwalithi ye-compact: Phakathi nenqubo yokucindezela, kufanele kube nesikhathi esifanele sokubamba ngaphansi kokucindezela okukhulu kokucindezela, okungakhuphula kakhulu ukuminyana kwe-compact.

Imishini yokubumba ye-powder metallurgy ezenzakalelayo ezenzakalelayo esanda kuthuthukiswa i-Chengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd. iklanywe njengesisetshenziswa esisha sokuphayona sasekhaya esihlanganisa izinzuzo zokunyathelisa ngemishini kanye ne-CNC servo hydraulic press.
Isisekelo sesikhunta esiyinhlanganisela sohlobo lwesifanekiso esintantayo samathuluzi singalawula ngempumelelo ukuhambisana komkhiqizo kanye nenani elifanelekile lomkhiqizo.Ngesisekelo sokwanelisa ukucindezela okuqhubekayo, inqubo emisiwe yokucindezela umshini womshini wokunyathelisa yengezwa, engakwazi nje ukusebenza njengomkhawulo kodwa futhi njengendlela yokucindezela ehleliwe.Ukuvikelwa kwezendlalelo ezimbili zokucindezela nokucindezela kuthuthukisa kakhulu ukunemba komkhiqizo nokusebenza kahle kokukhiqiza.
