U bona "high-press die casting" e beha maemo a ho etsa aluminium ea cast. Ts'ebetso ena e laola indasteri, e tšoere karolo e fetang 78% ea lekeno ka 2024. Makala a mangata, haholoholo.koloitlhahiso, itšetleha ka eona ho theha likarolo tse bobebe, tse nepahetseng tse ntlafatsang ts'ebetso ea mafura le ts'ebetso.

Lintlha tsa bohlokoa

• Ho lahlela lefu la khatello e phahamenge hlahisa likarolo tsa aluminium tse matla, tse nepahetseng ka potlako, e leng se etsang hore e be se loketseng bakeng sa tlhahiso ea boleng bo phahameng ka meralo e rarahaneng.
• Ts'ebetso ena e theha likarolo tse bobebe tse nang le pheletso e ntle haholo le mamello e thata, e fokotsang tlhoko ea mosebetsi o eketsehileng oa ho qeta.
• Theknoloji e tsoetseng pele le taolo ea bolengka ho lahla lihlahisoa ho ntlafatsa ts'ebetso ea lihlahisoa, ho fokotsa litšenyehelo, le ho tšehetsa mekhoa e tsitsitseng ea tlhahiso.

Ke Eng e Etsang Hore ho Latsoa ha High-Pressure Die ho ikhetha bakeng sa Cast Aluminium

The High-Pressure Die Casting Process

O qala kats'ebetso e phahameng ea khatello ea maikutloka ho lokisa hlobo ya tshepe. Basebetsi ba hloekisa le ho tlotsa hlobo ho thusa ho laola mocheso le ho etsa hore ho be bonolo ho tlosa karolo e felileng. Ka mor'a moo, o qhibilihisa motsoako oa aluminium ka sebōping. Ebe u fetisetsa tšepe e qhibilihisitsoeng ka har'a letsoho la ho thunngoa, hangata ka har'a sistimi e batang ea kamore hobane aluminium e qhibiliha ka mocheso o phahameng. Piston e kenya aluminium e qhibilihisitsoeng ka har'a hlobo e koetsoeng ka khatello e phahameng haholo - ka linako tse ling e fihla ho 1200 bar. Tšepe e tlatsa lintlha tsohle tsa hlobo ka potlako 'me e tiisa tlas'a khatello. Hang ha karolo e pholile, li-ejector pins li e sutumelletsa ka ntle ho hlobo. Qetellong, o fokotsa ntho leha e le efe e eketsehileng. Ts'ebetso ena e u lumella ho etsa likarolo tsa aluminium tse entsoeng ka marako a masesaane le libopeho tse rarahaneng ka metsotsoana feela.

Melemo e Ikhethileng ho Feta Mekhoa e meng ea ho Lahlela

High-pressure die casting e fapane le mekhoa e meng ka lebaka la lebelo la eona, ho nepahala le bokhoni ba ho etsa likarolo tse qaqileng. U ka bona liphapang ka ho hlaka tafoleng e ka tlase:

U rua molemo tlhahisong e potlakileng le ho pheta-pheta ho phahameng. Ts'ebetso ena e u fa mamello e thata le libaka tse boreleli, ho bolelang hore ho na le mosebetsi o fokolang oa ho qeta.Ho lahlela lefu la khatello e phahamenge loketse ha o hloka likarolo tse kholo tsa likarolo tsa aluminium tse matla le tse qaqileng.

Melemo ea Ts'ebetso ea ho Lahla Die ea Khatello e Holimo ka Aluminium ea Cast

Ho Nepahalla le ho tsitsisa

U fumana molemo o moholo kakhatello e phahameng ea maliha o hloka likarolo tsa aluminium tse nepahetseng le tse tsitsitseng. Ts'ebetso ena e sebelisa liforomo tse matla tsa tšepe le khatello e phahameng ea ente, e u lumellang hore u thehe likarolo tse nang le libopeho tse rarahaneng le lintlha tse ntle. U ka finyella marako a tšesaane le mamello e thata, e leng thata ka mekhoa e meng ea ho lahla. Mohlala, ho lahla lehlabathe hangata ho siea libaka tse makukuno le mabota a teteaneng, ha "die casting" e hlahisa liphetho tse boreleli le litekanyo tse nepahetseng haholoanyane.

U ka bona hore die casting e ikhethile ka bokhoni ba eona ba ho fana ka liphetho tse ts'oanang, haholo ha o hloka tse likete tse tšoanang.lahla likarolo tsa aluminium. Le ha ts'ebetso e le 'ngoe e ke ke ea lula e fihlela mamello e thata ka ho fetesisa (joalo ka ± 0.01 mm), o ka sebelisa machining a CNC kamora ho lahla ho fihlela litekanyo tsena tse nepahetseng. Tlhahlobo ea kamehla le taolo e hlokolosi ea ts'ebetso e u thusa ho boloka boleng bo phahameng ho tloha karolong e 'ngoe ho ea ho e 'ngoe.

Keletso:Haeba u batla sephetho se setle ka ho fetesisa le ho nepahala ha likarolo tsa hau tsa aluminium tse entsoeng ka tšepe, khetho e holimo ke eona khetho e holimo.

Matla a Mechini le ho tšoarella

Ha u khetha "high-press die casting", u fumana likarolo tsa aluminium tse nang le matla a tsotehang a mochine le nako e telele. Pholiso e potlakileng nakong ea ts'ebetso e theha sebopeho se setle sa grained microstructure, se matlafatsang matla le boleng ba holim'a metsi. U rua molemo molemong oa karo-karolelano ea aluminium e phahameng ea matla ho isa ho boima, e etsa hore e be e loketseng likarolo tse bobebe empa e le tse thata.

• Ente ea khatello e phahameng e fokotsa mefokolo e kang porosity le shrinkage, kahoo likarolo tsa hau li tšoarella nako e telele.
• Thermal conductivity e ntle haholo ea Aluminium e thusa likarolo tsa hau ho sebetsana le mocheso, o bohlokoa bakeng sa ts'ebeliso ea likoloi le tsa elektroniki.
• Sebopeho se setle sa lijo-thollo ho tloha ho tiisa ka potlako se eketsa ka bobeli ductility le ho hanyetsa ho phunyeha.

Mohlala, lisebelisoa tse ling tsa aluminium tsa HPDC li ka fihlella matla a lihlahisoa ho fihla ho 321 MPa le matla a ho qetela a 425 MPa kamora kalafo ea mocheso. Linomoro tsena li bontša hore u ka itšetleha ka likarolo tsa aluminium bakeng sa mesebetsi e boima, ho tloha lienjineng tsa likoloi ho ea ho liforeimi tsa sefofane.

Katleho ea Litšenyehelo le Tlhahiso

U boloka nako le chelete ka mokhoa o phahameng oa khatello ea maikutlo. Mokhoa ona o u lumella ho hlahisa likarolo tse ngata tsa aluminium ka potlako, ka lebaka la linako tse potlakileng tsa potoloho le hlobo e ka sebelisoang hape. U ka etsa libopeho tse rarahaneng ka metsotsoana, ho bolelang hore u arabela ka potlako litlhoko tsa 'maraka.

• Sistimi e ikemetseng le meralo ea hlobo e tsoetseng pele e fokotsa liphoso le nako ea ho theoha.
• Hangata o hloka machining a fokolang le ho qeta, e leng ho fokotsa litšenyehelo tsa hau ka kakaretso.
• Mehlala ea 'nete ea lefats'e e bonts'a linako tse khuts'oane tsa 20% le 30% ea litšenyehelo tse tlase tsa tlhahiso bakeng sa lihlahisoa tse ling.

U ka bona hore le hoja ts'ebetso e 'ngoe ea morao-rao e hlokahala, lebelo ka kakaretso le katleho ea ho lahla ha khatello e phahameng e etsa hore e be khetho e bohlale bakeng sa tlhahiso ea aluminium e nang le li-volume tse phahameng.

Melemo ea Tikoloho le Moshoelella

U thusa tikoloho ha u sebelisa "high-press die casting" bakeng sa likarolo tse entsoeng ka aluminium. Ts'ebetso e ts'ehetsa ho sebelisoa hape le ho fokotsa litšila, e leng ntho ea bohlokoa bakeng sa tlhahiso e tsitsitseng.

• U ka sebelisa li-alloys tsa aluminium tse nchafalitsoeng, tse bolokang matla a fihlang ho 95% ha a bapisoa le ho etsa aluminium e ncha ka tšepe.
• Ts'ebetso e hlahisa likhechana tse nyane ka lebaka la ho nepahala ha tsona, 'me u ka khona ho khutlisa le ho sebelisa likhechana tsa trim hape.
• Boima bo bobebe ba Aluminium bo bolela hore lihlahisoa tse kang likoloi le lifofane li sebelisa mafura a fokolang, li theola mesi bophelong bohle ba tsona.
• Baetsi ba bangata ba sebelisa libopi tse baballang matla le mehloli ea matla a ka nchafatsoang ho fokotsa ho ntšoa ha khabone.

Hlokomela:Ka ho khetha "high-press die casting", o ts'ehetsa moruo o potolohang le ho thusa ho fihlela lipheo tsa ts'ebetso tsa lefats'e.

Ho Fumana Bokhabane ho Cast Aluminium ka Theknoloji e tsoetseng pele

Karolo ea Thepa ea Kajeno le Boiketsetso

U fumana boleng bo holimo le bokhabane tlhahisong ea aluminium ea cast ka ho sebelisa lisebelisoa tsa sejoale-joale le boiketsetso. Mechini ea kajeno ea ho lahla e sebelisa li-sensor le ho beha leihlo ka nako ea nnete ho lokisa maemo a ts'ebetso hanghang. Theknoloji ena e u thusa ho fokotsa liphoso le ho boloka liphetho tse tsitsitseng. Automation e boetse e tlisa li-ladle tsa liroboto le lits'ebetso tsa ho sebetsana le ts'ebetso ea hau ea mosebetsi. Liroboto tsena li ntlafatsa polokeho ea sebaka sa mosebetsi le ho netefatsa hore karolo ka 'ngoe e fihlela litekanyetso tse thata.

U rua molemo ho likhatelopele tse 'maloa tsa morao-rao:

• Li-sensor ka mochini li lumella liphetoho tsa nako ea nnete, ho fokotsa liphoso.
• Software ea simulation e u thusa ho rala liforomo tse betere le ho bolela esale pele liphetho.
• Mekhoa e thusang ka vacuum le extrusion die casting e ntlafatsa boleng ba bokaholimo le boleng ba sehlahisoa.
• Sistimi ea liroboto e sebetsana le mesebetsi e kotsi, e boloka sehlopha sa hau se bolokehile.
• Li-motor tse sebetsang hantle le moholi li koahela litšenyehelo tse tlase le ho ts'ehetsa ts'ebetso.
• IIoT (Industrial Internet of Things) e hokela mechini ea hau bakeng sa tlhahiso e bohlale, tlhokomelo e boletsoeng esale pele, le liphetoho tse potlakileng tsa ts'ebetso.

Ka lisebelisoa tsena, o ka hlahisa likarolo tsa aluminium tsa cast ka potlako, ka mefokolo e fokolang, le ka theko e tlase.
