Powder metallurgy compression molding process

Metallurgy ea phofo (Metallurgy ea phofo, e bitsoang PM) ke theknoloji ea metallurgic eo ho eona phofo ea tšepe (kapa motsoako oa phofo ea tšepe le phofo e seng ea tšepe) e sebelisoang e le lisebelisoa tse tala ho etsa lihlahisoa tsa tšepe kapa thepa ka ho etsa, ho sintering kapa ho etsa mocheso.Ts'ebetso ea tlhahiso ea metallurgy ea phofo e tšoana le mokhoa oa tlhahiso ea lihlahisoa tsa ceramic, kahoo batho ba atisa ho bitsa mokhoa oa phofo oa metallurgy "cermet method".
Ka tsoelo-pele e potlakileng ea maemo ohle a bophelo, litlhoko tse fapaneng tse kang moralo o bobebe le o kopaneng, likarolo tse ngata li ntse li fetoha tse rarahaneng, tse etsang hore mokhoa oa ho bopa oa phofo o tobane le mathata a mangata.
Ka keketseho ea palo ea PM, litlhoko tsa ts'ebetso li tlameha ho ba thata haholoanyane.E le thepa ea bohlokoa ka ho fetisisa holim'a karolo ea tlhahiso ea phofo ea metallurgy, mochine oa khatiso oa phofo o etsang hydraulic o etsa qeto ea hore na boleng ba phofo ea compact le ho thibela nts'etsopele ea indasteri ea phofo ea metallurgy Chaena..Mochine oa khatiso oa phofo o sebetsang hantle ke phofo e etsang sehlahisoa sa khatiso ea hydraulic e thehiloeng ho theknoloji ea electro-hydraulic ratio, empa theknoloji ea eona e boemong bo koetsoeng.
Hona joale, limela tse kholoanyane tsa tlhahiso ea metallurgy li hlahisitse lisebelisoa tse tsoetseng pele tsa ho etsa phofo le mela ea tlhahiso e tsoang linaheng tse ling, empa kenyelletso feela e ke ke ea rarolla bothata ka mokhoa o hlakileng.Ka hona, nts'etsopele e ikemetseng ea lisebelisoa tse phahameng tsa theknoloji ea phofo e boetse e le mokhoa o moholo oa nts'etsopele ea indasteri ea phofo.

Mokhoa oa ho etsa phofo ea metallurgy
Ho theha ke mohato oa bohlokoa ts'ebetsong ea phofo ea metallurgy.Sepheo sa ho bopa ke ho hlahisa compact e nang le sebopeho se itseng, boholo, boima le matla.Ho etsa compression ke mokhoa oa mantlha oa ho theha.
Mokhoa oa ho bopa oa compression o na le ts'ebetso e bonolo, ts'ebetso e phahameng, 'me e loketse tlhahiso ea othomathike.Leha ho le joalo, kabo ea khatello ea mokhoa ona ha e tšoane, e le hore boima ba 'mele o motala ha bo tšoane,' me ho phunyeha ho tloaelehile ho etsahala, ho lebisang ho ponahalo ea lihlahisoa tse nang le bokooa.
a.Ho ts'oana ha sekhahla sa ho ajoa ha compact: Hobane 'mele oa phofo o phalla ka mahlakoreng' ohle ka mor'a ho hatelloa ha lefu, o baka khatello ea mahlakoreng e pota-potileng lebota la lefu.Khatello ea mahlakoreng e baka khohlano, e leng ho tla baka ho theoha ho hoholo ha khatello ka lehlakoreng la bophahamo ba compact.
Mehato ea ntlafatso: 1) Fokotsa ho ferekana, sebelisa oli e tlotsang leboteng le ka hare kapa u sebelise hlobo e nang le lerako le ka hare le boreleli;
2) Ho hatella ka litsela tse peli ho sebelisoa ho ntlafatsa ho se leka-lekane ha kabo ea li-compact tse tala;
3) Leka ho fokotsa tekanyo ea bophara-bophara ha u rala hlobo.
b.Ho theola bots'epehi: ka lebaka la ho atolosoa ha hlobo ea mosali nakong ea ts'ebetso ea ho hatella, ha khatello e tlosoa, compact e sitisa ho koeneha ha hlobo ea basali, 'me compact e ba tlas'a khatello ea radial, e leng se etsang hore compact e amohele ho kuta ka morao. khatello ea maikutlo nakong ea ts'ebetso ea ho senya Matheba a mang a fokolang holim'a compact a ka 'na a senngoa tlas'a khatello ea ho kuta e boletsoeng ka holimo.
Mehato ea ntlafatso: Mabapi le sebopeho, likarolo li lokela ho qoba li-grooves tse nang le marako a tšesaane, a tebileng le a moqotetsane, likhahla tse bohale, tse nyenyane le tse nyenyane le libopeho tse ling ka hohle kamoo ho ka khonehang.
Ho tsoa lintlheng tse peli tse ka holimo, tlhaloso e boima ea phello ea ntlha e le 'ngoe tsamaisong ea ho laola boleng ba sehlahisoa, empa ka mekhoa e sebetsang, lintlha tse sa tšoaneng tse susumetsang li lumellana.Nakong ea ts'ebetso ea lipatlisiso, ho fumanoa hore lintlha tse amang boleng ba sehlahisoa ka nako e le 'ngoe ke:
1. Tšusumetso ea ho theha khatello ea boleng ba billet: matla a ho hatella a na le tšusumetso e tobileng ho boima ba 'mele.Ho theoha ha khatello e teng ho baka delamination le peeling nakong ea ho hatella, 'me mapetsong a teng ho sebopeho sa compact ka mor'a ho phunya.
2. Phello ea lebelo la ho hatella boleng ba compact: Nakong ea phofshoana ea phofshoana, lebelo la ho hatella le ama ho tsoa ha moea ho tloha ho li-pores pakeng tsa li-powders, 'me ka ho toba le ama ho tšoana ha li-compact density.Phapang ea tekano ea compact e batla e le kholo.Ho bonolo ho hlahisa mapetsong.
3. Tšusumetso ea ho tšoara nako ka boleng ba compact: Nakong ea ts'ebetso ea ho hatella, ho tlameha ho ba le nako e loketseng ea ho tšoara tlas'a khatello e phahameng ea khatello, e ka eketsang haholo boima ba compact.

Thepa ea ho bopa ea phofo ea othomathike ka botlalo e sa tsoa ntlafatsoa ke Chengdu Zhengxi Hydraulic Equipment Manufacturing Co., Ltd. e entsoe e le sesebelisoa se secha sa bopula-maliboho ba malapeng se kopanyang melemo ea mochini oa khatiso le oa CNC servo hydraulic.
The floating thempleite mofuta oa motsoako motheo oa thepa e ka laola ka katleho ho tsitsana ha sehlahisoa le sekhahla se tšoanelehang sa sehlahisoa.Motheong oa ho khotsofatsa khatello e sa khaotseng ea khatello, mokhoa o tsitsitseng oa ho hatella mochine oa mochine oa mochine o kenngoa, o ke keng oa sebetsa feela e le moeli empa hape e le mokhoa o tsitsitseng oa ho hatella.Tšireletso ea mekhahlelo e 'meli ea ho hatella le ho hatella e ntlafatsa haholo ho nepahala ha sehlahisoa le katleho ea tlhahiso.
