Moralo oa Sefe sa Extrusion: Jeometri ea sekoti sa Die e hlalosa boholo le sebopeho sa ho qetela sa profil ka 'ngoe. Baenjiniere ba leka-lekanya ntlafatso ea phallo ea tšepe, ho rarahana ha karolo, le ho tšoarella ha sefe nakong ea moralo.
Taolo ea ho Futhumatsa ha Billet le Thermal: Mocheso o tšoanang oa billet o netefatsa phallo e tsitsitseng ea aluminium ka har'a cavity ea die, e tsitsisa thepa ea 'mele le ho tšoana ha boholo ba liprofaele tse felileng.
Kgatelelo ya ho ntsha le Lebelo la Mohala: Kgatelelo e lokisitsweng le diparamithara tsa lebelo di netefatsa mamello e nepahetseng ya boholo. Botenya ba lebota la profaele, ho rarahana ha jeometri, le qetello ya bokahodimo kaofela di hloka ditlhophiso tsa lebelo/kgatelelo tse ikgethileng.
Tsamaiso ea Kamora ho Ntša: Ho futhumatsa mocheso, kalafo ea bokaholimo, le ho seha bolelele bo ikhethileng ho fetola thepa ea mechini le ponahalo ea botle ho fihlela litlhoko tsa projeke.
Tlhahlobo le Taolo ea Boleng bo Hare: Liprofaele tse nang le jiometri ea angular e fetang 45° li hloka tlhokomelo e tiileng ea ts'ebetso ka nako ea sebele. Teko e felletseng ea litekanyo, liteko tsa botšepehi ba bokaholimo, le netefatso ea matla bakeng sa netefatso e felletseng ea boleng.
Tsoelo-pele ea boiketsetso ba extrusion e ntlafalitse haholo botsitso le katleho ea tlhahiso ea liprofaele tsa aluminium tse bōpehileng joaloka tse entsoeng ka mokhoa o ikhethileng tlhahisong ea sejoale-joale.
6. Lipotso Tse Botsoang Khafetsa (Lipotso Tse Botsoang Khafetsa)
Kotara ea 1Hlalosa mokhoa oa ho ntša aluminium
K: Ho ntsha aluminium ho bopa thepa ya alloy ya aluminium hore e be diprofaele tse tshwanang tsa dikarolo tse tshekaletseng ka ho qobella di-billet tse futhumatswang ka hara di-dies tse entsweng ka nepo. Ramoro ya hydraulic e sutumelletsa aluminium e chesang ka hara sekoti sa die, e etsa diprofaele tse tswelang pele tsa bolelele bo bolelele tse nang le jiometri e tshwanang ya dikarolo tse tshekaletseng. Mokgwa ona o sebetsang wa tlhahiso o tshehetsa dijiometri tse rarahaneng le tshebediso e pharalletseng ya indasteri.
Kotara ea BobeliPhapang ke efe pakeng tsa ho ntša ka ho toba le ho sa tobang?
K: Ha ho ntšoa ka ho toba, billet ea aluminium e tlala ka har'a silindara ea khatiso, 'me pheleu e sutumelletsa thepa e tala pele ka har'a die e sa sisinyeheng. Ha ho ntšoa ka ho sa tobang, pheleu e jara kopano ea die 'me e sutumelletsa die holim'a billet e tsitsitseng, e fokotsa khohlano ea thepa ea ka hare le ho fokotsa matla a hlokahalang a hydraulic.
Kotara ea 3Hobaneng mocheso oa extrusion o le bohlokoa ts'ebetsong?
K: Mocheso o ama ka ho toba phallo ea alloy ea aluminium ka har'a die le boleng ba ho qetela ba liprofaele tse ntšitsoeng. Ho futhumatsa ho laoloang ho nolofalletsa phallo e ntle ea tšepe, matla a ho tsitlella a tsitsitseng, le liphetho tse boreleli, tse se nang sekoli holim'a metsi.
Kotara ea boneHlalosa melao-motheo ea motheo ea moralo oa extrusion ea aluminium
K: Boenjiniere ba moralo oa extrusion bo akaretsa moralo oa botenya ba lebota, mamello ea litekanyo, litumello tsa machining bakeng sa ts'ebetso ea kamora ho sebetsa, le lipalo tsa ho tlosa ram/tooling. Moralo o nepahetseng o netefatsa hore likarolo tse extruded li ka etsoa ka katleho ha li ntse li fihlela litlhoko tsohle tsa ts'ebetso ea ho qetela.
Q5Ke hobane'ng ha li-extrusion tsa aluminium tsa T-slot li tumme haholo?
K: Di-extrusion tsa T-slot di nolofalletsa kopano e bonolo, phetoho e bonolo ya sebopeho, le ho feto-fetoha ha diforeimi le meaho ya disebediswa. Di fana ka kganyetso e ikgethang ya mafome le ho tenyetseha ha meralo bakeng sa diporojeke tsa diindasteri tse ikgethileng makaleng ohle.
Q6Ke mehato efe ea taolo ea boleng e netefatsang botšepehi ba weld ea extrusion?
K: Botšepehi ba morumo o tsitsitseng oa welding bo itšetlehile ka lisebelisoa tse hlakileng le tse hloekileng tsa die, tlhokomelo ea kamehla ea die, ho futhumatsa hantle pele ho billet, le tlhokomelo e felletseng ea mohala oa tlhahiso. Litaolo tsena li felisa li-seam tse fokolang 'me li tiisa botsitso ba sebopeho bakeng sa liprofaele tse felileng.
Q7Lisebelisoa tsa ho ntša aluminium ke eng? Hlalosa ka mehlala
K: Lisebelisoa tsa ho ntša thepa li bolela likarolo tsohle tse entsoeng ka mochini o nepahetseng tse etsang liprofaele tsa aluminium, ho kenyeletsoa le li-dies, mandrels le lisebelisoa tse tšehetsang. Lisebelisoa tsa boleng bo holimo li fana ka ts'ebetso e tsitsitseng ea ho ntša thepa, ho nepahala ho tsitsitseng ha litekanyo, le boleng bo tšoanang ba sehlahisoa se felileng.
Q8Mosebetsi oa tafole ea extrusion runout ke ofe?
K: Tafole e phallang e tšehetsa le ho pholisa liprofaele tsa aluminium e chesang hang ka mor'a hore li tsoe ka har'a dae. Ho lokisa le ho hlokomela tafole hantle ho fokotsa liphoso tsa bokaholimo le ho boloka litekanyo tse entsoeng ka mokhoa oa sefapano sa setoko se ntšitsoeng.
Q9Phapang ke efe pakeng tsa ditempera tsa extrusion tsa aluminium tsa T5 le T6?
A: T5 le T6 ke mabitso a tloaelehileng a mocheso oa aluminium e ntšitsoeng. T5 e kenyelletsa ho pholisa moea ka mor'a ho ntšetsoa ka ntle ho aluminium e lateloang ke botsofali ba maiketsetso. T6 e eketsa mohato o eketsehileng oa kalafo ea mocheso o felletseng, e fanang ka matla a ho thapolla a phahameng haholo bakeng sa lits'ebetso tsa meaho e boima.
