Ho Hloekisa le ho Seha Di-Casting tsa Aluminium Alloy

Ho Hloekisa le ho Seha Li-Die-Casting tsa Aluminium Alloy: Ho tloha Litlhalosong tsa Ts'ebetso ho ea ho Taolo ea Boleng bakeng sa Khoebo ea Machabeng

Ka hare ho lahla die-casting ka alloy ea aluminium Ketane ea indasteri, ho hloekisa le ho seha li-castings ke khokahano ea bohlokoa pakeng tsa ho etsa die-casting le ts'ebetso e latelang. Ha e khetholle feela ponahalo ea sehlahisoa, ho nepahala le ho lekana ha sona, empa hape e ama ka kotloloho bophelo ba sehlahisoa le polokeho ea sona. Bakeng sa ho romela kantle ho naha, lits'ebetso tsa ho hloekisa le ho seha tse fihlelang maemo a machaba ke monyetla oa tlholisano oa bohlokoa bakeng sa ho hlola litšitiso tsa khoebo le ho fumana tšepo ea bareki ba mose ho maoatle. Sengoloa sena se sekaseka ka mokhoa o hlophisehileng likarolo tsa bohlokoa tsa botekgeniki tsa ts'ebetso ea ho hloekisa le ho seha bakeng sa li-castings tsa alloy die-castings tsa aluminium, se fana ka tharollo e felletseng bakeng sa lik'hamphani tsa kantle ho naha, ho tloha ts'ebetsong ea ts'ebetso ho isa ho lateleng boleng.

Sa pele, sepheo sa mantlha sa ho hlwekisa le ho qeta: Hobaneng e le "moeli oa boleng" bakeng sa ho romela thepa kantle ho naha

Kamora ho tjheseletsa ka alloy ea aluminium, liphoso tse kang li-sprues, li-burrs, sekala le matheba a oli hangata li sala holim'a bokaholimo le kahare ho tjheseletsa. Haeba li sa rarolloe kapele, liphoso tsena li ka lebisa mathateng a mararo a mantlha:

Ho hloleha ha kopano: Leseli le setseng le ka baka dibaka tse ngata pakeng tsa dikarolo, haholoholo ditshebedisong tse nepahetseng haholo tse kang tsa dikoloi le tsa puisano, e leng se lebisang mathateng a kang lerata le sa tlwaelehang le ho kwalwa hampe.

Boleng ba bokaholimo bo sa lokelang: Matheba a sekala le oli a ka ama mekhoa e latelang ea phekolo ea bokaholimo joalo ka ho penta le ho penta ka motlakase, e leng se sitisang litlhoko tse thata tsa ponahalo ea limmaraka tsa Europe le Amerika.

Likotsi tse patehileng: Masalla a tšepe a ka robeha nakong ea tšebeliso 'me a senya likarolo tse ka hare (joalo ka litsamaiso tsa hydraulic le likarolo tsa enjene). Ka hona, ho hloekisa le ho qeta ka botsebi ho tlameha ho fihlella lipheo tse 'ne tse kholo:

Tlosa ka botlalo lintho tse tsoang kantle ho naha (flash, burrs, le masala a sprue) ho tsoa ho Ho lahla Bokaholimo le lesoba;

Netefatsa hore ho nepahala ha ho lahla ho fihlela mamello ea ho taka (hangata ho ka hare ho ± 0.05mm);

Ntlafatsa ho hlaka ha bokaholimo (Boleng ba Ra bo lokela ho tloha ho 1.6 ho isa ho 6.3μm ho latela ts'ebeliso);

Tlosa mefokolo e ka bang teng (mohlala, kalafo ea mapetso a manyenyane le li-pores pele ho nako).

Ea bobeli, Phallo e Tloaelehileng ea Ts'ebetso: Mokhoa oa Mehato e Mene ho tloha Pele ho Phekolo ho ea Boleng ba Loop e Koetsoeng

1. Kalafo Pele ho Nako: Ho Tloswa ha Diphoso tse Kgolo ka Sepheo

Kalafo esale pele ke motheo oa ho hloekisa, 'me ts'ebetso e lokela ho khethoa ho latela sebopeho sa ho lahla le mofuta oa sekoli:

Ho Tlosa Riser:

Di-cast tse nyane le tse mahareng (tse kang matlo a puisano le dihokelo): Sebedisa di-shear tsa haeteroliki kapa tsa pneumatic tse nang le sekgahla sa tlhahiso sa dikotwana tse 300-500/hora ho qoba ho fetoha ho bakwang ke tshusumetso ya mechini.

Likarolo tse kholo le tse rarahaneng (tse kang matlo a phetiso ea likoloi): Sebelisa lisakha tsa CNC bakeng sa ho seha ka nepo, ho fihlella mamello e bataletseng ea ≤0.1mm, ho fokotsa mosebetsi o latelang oa ho bentša.

Ho Tloswa ha Di-Burrs le Flash Pele:

Ho sila ka holim'a metsi a bataletseng: Sila ka mokhoa o batlang o le bonolo ka sander ea lebanta u sebelisa mochini oa sanding oa grit oa 80-120 ho tlosa flash e kholo ho feta 0.5mm.

Likarolo tse tebileng/tse bōpehileng joaloka tse khethehileng (joalo ka li-end caps tsa enjene): Sebelisa lifaele tsa letsoho kapa lisebelisoa tse nyenyane tsa pneumatic ho qoba tšenyo leboteng le ka hare la cast.
2. Ho Hloekisa Bokaholimo bo Tebileng: Ho Leka-lekanya Bokgoni le Ntlafatso
Ho latela litlhoko tsa boleng ba bokaholimo ba bareki ba khoebo ea kantle ho naha, lits'ebetso tse tharo tse kholo tse latelang li ka khethoa:

3. Ho Qetella ka ho Nepahetseng: Litekanyo tsa ho Laola le Lintlha tsa Ponahalo
Ts'ebetso ea ho qeta e etsa qeto ka kotloloho hore na ho lahlela e fihlela litlhoko tsa kopano. Lintlha tsa bohlokoa li kenyelletsa:
Ho Qetella ka Dimensional: Ho sila kapa ho sila ha CNC ho sebediswa ho sebetsa hodima dibaka tsa ditshupiso tsa senotlolo (jwalo ka dibaka tsa flange le ho fumana masoba) ho netefatsa hore dimensional tolerances di fihlella maemo a ISO 8062 (mohlala, dimensional tolerances tsa H11);
Tokiso e Phethahetseng ea Liphoso: Bakeng sa masoba a manyane (bophara ba ≤0.5mm), ho tjheseletsa arc ea argon ho etsoa ka ho sebelisa terata ea ho tjheseletsa e ikhethileng ka alloy ea aluminium. Kamora ho tjheseletsa, ho tjheseletsa ho tlameha ho qhibilihisoa ka mobu le substrate ho qoba ho ama pente e latelang;
Ho Selika-likoe ka Moeli: Meeli e bohale ea ho lahla e chitja (radius ea R0.2-0.5mm) ho ntlafatsa polokeho le ho fokotsa tšenyo nakong ea lipalangoang. 4. Tlhahlobo ea Boleng: Theha Sistimi ea ho Latela Boleng bakeng sa Khoebo ea Kantle ho Naha

Kamora ho hlwekisa le ho qeta, tlhahlobo e tlameha ho akaretsa mahlakore a mararo ho netefatsa hore e latela ditlhoko tsa tlhahlobo ya fektheri ya bareki ba mose ho maoatle:
Tlhahlobo ea Ponahalo: Tlhahlobo ea pono (khanya ea ≥ 500 lux) kapa lisebelisoa tsa tlhahlobo ea pono tse iketsang li lokela ho sebelisoa ho netefatsa hore ha ho na khanya e bonahalang, mengoapo, kapa liphetoho tsa 'mala.
Tlhahlobo ea Litekanyo: Litekanyo tsa bohlokoa li qotsoa le ho hlahlojoa ho sebelisoa mochini o lekanyang oa likhokahano tsa mahlakore a mararo (ho nepahala ± 0.001mm), ka karolelano ea ho qotsa e seng ka tlase ho 5%.
Teko e sa senyeheng: Tlhahlobo ea X-ray kapa teko ea ho kenella e etsoa likarolong tse jarang mojaro (joalo ka likarolo tsa ho emisoa ha likoloi) ho netefatsa hore ha ho na liphoso tsa ka hare tse kang ho kenella ha weld ho sa fellang le mapetso. Litlaleho tsa tlhahlobo li tlameha ho fanoa hammoho le thepa e rometsoeng.

Ntlha ea boraro, Lintlha tsa bohlokoa tsa tekheniki le likhopolo tse fosahetseng tseo u lokelang ho li qoba maemong a khoebo ea kantle ho naha

1. Lintlha tsa Tekheniki: Ho Ikamahanya le Litlhoko tse Fapaneng tsa 'Maraka oa Thepa e Romelloang Kantle

Bareki ba Indasteri ea Likoloi (mohlala, baetsi ba likoloi ba Amerika Leboea le Europe): Ho ba thata ha bokaholimo (Ra ≤ 3.2μm) ho tlameha ho laoloa, 'me kalafo ea ho thibela mafome (mohlala, ho se be le chromium) e tlameha ho etsoa kamora ho hloekisoa. Teko ea ho fafatsa ka letsoai e tlameha ho netefatsa boemo ba ho se be le mafome lihora tse 72.

Bareki ba Indasteri ea Lipuisano (mohlala, basebetsi ba Asia Boroa-bochabela le Bochabela bo Hare): Tsepamisa maikutlo ts'ebetsong ea ho qhala mocheso oa li-castings. Nakong ea ho hloekisa, botšepehi ba sinki ea mocheso bo tlameha ho bolokoa ho qoba ho bentša ho feteletseng ho fokotsang katleho ea ho qhala mocheso.

Bareki ba Lisebelisoa tsa Bongaka (mohlala, limmaraka tsa Europe le Amerika): Mekhoa ea ho hloekisa e se nang li-septic (mohlala, ho hloekisa ka ultrasound le metsi a hloekileng) e tlameha ho sebelisoa, 'me tlaleho ea teko ea bohloeki (boholo ba likaroloana ≤ 10μm) e tlameha ho fanoa kamora ho hloekisa.
2. Ho Qoba Liphoso Tse Tloaelehileng
Phoso ea 1: Ho itšetleha haholo ka ho hloekisa ka mechine ho lebisa botenya ba lebota bo sa lekanang. Tharollo: Bakeng sa likarolo tse nang le mabota a masesaane (botenya ba lebota ≤ 2mm), ts'ebetso e kopaneng ea "ho hloekisa lik'hemik'hale + ho qeta ka letsoho" e sebelisoa ho qoba ho fetoha ho bakoang ke khatello ea mechini.
Phoso ea 2: Ho hlokomoloha ho imolla khatello ea maikutlo ka mor'a ho hloekisa. Tharollo: Etsa kalafo ea botsofali mochesong o tlase (120-150°C ka lihora tse 2-4) ka mor'a ho hloekisa le ho qeta ho lokolla khatello ea ka hare le ho thibela ho petsoha nakong ea lipalangoang.
Phoso ea 3: Lirekoto tsa tlhahlobo tse sa fellang. Tharollo: Theha sistimi ea ho latela mokhoa oa dijithale ho rekota liparamente tsa ts'ebetso ea ho hloekisa le liphetho tsa tlhahlobo bakeng sa sehlopha se seng le se seng ho fihlela litlhoko tsa ho latela mokhoa oa bareki.

Sa bone, Qetello: Ho aha Tlholisano ya Motheo Kgwebisanong ya Kantle ho Naha ka Bokgoni ba Setsebi
Ho hlwekisa le ho phethela ha li-castings tsa alloy ea aluminium ke mosebetsi oa botekgeniki le oa boitšoaro. Ha e leke feela bokhoni ba theknoloji ba k'hamphani empa hape e lekola kutloisiso ea eona e tebileng ea litlhoko tsa bareki ba mose ho maoatle.
