1. Molao-motheo oa extrusion ea aluminium

Extrusion ke mokhoa oa ho sebetsa oa extruding o kenyang matla a ka ntle holim'a billet ea tšepe ka har'a setshelo (silindara ea extrusion) mme e etsa hore e phalle ka lesoba le itseng la shoa ho fumana sebopeho le boholo ba karolo e lakatsehang.

2. Karolo ea aluminium extruder

The extruder e entsoe ka foreimi, foreimi e ka pele ea kholomo, kholomo ea katoloso, cylinder ea extrusion, sistimi ea hydraulic tlasa taolo ea motlakase, hape e na le setsi sa hlobo, thimble, poleiti ea sekala, poleiti ea li-slide joalo-joalo.

3. Ho hlophisoa ha mokhoa oa aluminium extrusion

Ho ea ka mofuta oa tšepe ka silindara ea extrusion: Tataiso ea khatello ea maikutlo le boemo ba khatello, extrusion, lubricating state, mocheso oa extrusion, lebelo la extrusion, kapa mefuta ea sebopeho se tsoetseng pele, sebopeho le che. ea sekheo kapa ea mofuta oa sehlahisoa, e ka aroloa ka extrusion positive, morao extrusion, (ho akarelletsa le sefofane strain extrusion, axisymmetric deformation extrusion, kakaretso tharo-dimensional deformation extrusion) lateral extrusion, khalase lubricating extrusion, Hydrostatic extrusion, extrusion tsoelang pele joalo-joalo.

4. Forever thermal deformation ea aluminium extrusion

Boholo ba likhoebo tse hlahisang aluminium tse chesang li sebelisa mokhoa oa pele oa ho chesa deformation extrusion ka lefu le itseng (flat die, cone die, shunt die) ho fumana lintlha tse lumellanang tsa aluminium tse nang le karolo le sebopeho se lakatsehang.

Ts'ebetso ea pele ea extrusion e bonolo, litlhoko tsa lisebelisoa ha li phahame, matla a ho senya tšepe a phahame, mefuta e mengata ea tlhahiso e pharaletseng, ts'ebetso ea aluminium e khona ho laola, ho fetoha ha maemo ho hoholo, 'me hlobo e bonolo ho e boloka le ho e ntlafatsa.

Sekoli se na le khohlano ea bokaholimo ho tloha ka har'a tube ea aluminium e kahare ea aluminium, tšebeliso ea matla e phahame, silinda ea likhohlano e bonolo ho etsa mocheso oa mocheso, 'me e eketsa botsitso ba profil, e fokotsa ts'ebetso ea ho qeta sehlahisoa, fokotsa lebelo la aluminium le aluminium alloy extrusion, ho apara ka potlako le bophelo ba ts'ebeletso ea extrusion die, lihlahisoa tse sa lekanang.

5. Mofuta oa hot deformation aluminium alloy, tshebetso le tšebeliso

Mefuta ea alloy ea aluminium e chesang e arotsoe ka mekhahlelo e 8 ho latela ts'ebetso le ts'ebeliso, ts'ebetso le ts'ebeliso ea tsona li fapane:

1) Aluminium e hloekileng (L letoto) e tsamaellanang le mofuta oa machaba oa 1000 letoto la aluminium e hloekileng.

Aluminium e hloekileng ea indasteri, machinability e babatsehang, ho hanyetsa kutu, ka phekolo ea holim'a metsi le motlakase oa motlakase, empa matla a tlaase, a sebelisoang ka thepa ea ntlo, lihlahisoa tsa motlakase, meriana le liphutheloana tsa lijo, thepa ea phetisetso le kabo, joalo-joalo.

2) Duralumin (Ly) e lumellana le letšoao la machaba la 2000 Al-Cu (Aluminium-copper) alloy.

E sebelisoa ka likarolo tse kholo, litšehetso, litaba tse phahameng tsa Cu, ho hanyetsa ha kutu.

3) Rust-proof aluminium (LF) e tsamaellanang le mofuta oa machaba oa 3000 Al-Mn (aluminium manganese) alloy.

Phekolo ea mocheso ha e matlafatsoe, machinability, ho hanyetsa kutu le aluminium e hloekileng, matla a ntlafalitsoe, ts'ebetso e ntle ea welding, e sebelisoang haholo litlhoko tsa letsatsi le letsatsi, thepa ea mohaho, lisebelisoa le likarolo tse ling.

4) Aluminium e khethehileng (LT) e lumellanang le letšoao la machaba la 4000 Al-Si alloy.

Haholo-holo thepa ea ho tjheseletsa, ntlha e tlaase ea ho qhibiliha (likhato tse 575-630), metsi a matle.

5) Anti-rust aluminium (LF) e lumellanang le letšoao la machaba la 5000Al-Mg (aluminium le magnesium) alloy.

Kalafo ea mocheso ha e matlafatsoe, ho hanyetsa kutu, ho cheseha, ho phatsima ha holimo, ka ho laola litaba tsa Mg, ho ka fumana maemo a fapaneng a matla a alloy. Boemo bo tlaase bakeng sa lisebelisoa tse khabisitsoeng, lisebelisoa tse tsoetseng pele; Boemo bo mahareng bakeng sa likepe, likoloi, thepa ea kaho; Boemo bo phahameng bo sebelisetsoang likarolo tsa ho cheselletsa limela tsa lik'hemik'hale tsa likepe le likoloi.

6) 6000Al-Mg-Si motsoako.

Mg2Si precipitation e thatafatsa phekolo ea mocheso e ka matlafatsa motsoako, ho hanyetsa kutu e ntle, matla a itekanetseng, ho sebetsa hantle ha mocheso, kahoo e sebelisoa haholo e le thepa ea extrusion, sebopeho se setle, boima bo phahameng bo ka fumanoa ka ho tima. E sebelisoa haholo ho aha li-profiles mme ke mohloli o ka sehloohong oa thepa indastering.

7) Superhard aluminium (LC) e lumellana le mofuta oa machaba oa 7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) alloy ea matla a phahameng a aluminium le Al-Zn-Mg alloy e sebelisetsoang likarolo tsa welding, tse nang le matla a phahameng, ts'ebetso e babatsehang ea ho cheselletsa le ho tima, empa khatello ea kelello e futsanehileng e hloka ho senyeha ha mocheso le ho hanyetsa mocheso. Ea pele e sebelisoa haholo-holo bakeng sa lifofane le thepa ea lipapali, ha ea morao-rao e sebelisoa haholo-holo bakeng sa ho tjheseletsa thepa ea meralo ea likoloi tsa terene.

8) 8000 (Al-Li) Aluminium-lithium motsoako.

The tšobotsi kholo ka ho fetisisa ke hore segokanyipalo ke 8% -9% ka tlaase ho 7000-letoto, phahameng rigidity, matla a phahameng, boima bo bobebe, letoto lena le tlas'a nts'etsopele (bokhoni ba ho thibela ho bola ha tšepe ea aluminium tlas'a maemo a thata ha bo e-s'o hlōloe ka ho feletseng), haholo-holo e sebelisoang ka lifofane, limisaele, lienjiniere le lisebelisoa tse ling tsa sesole.
