Lipoleiti tsa aluminium tsa 7xxx li tsebahala ka tekanyo ea tsona e ikhethang ea boima ba 'mele, e leng se etsang hore e be khetho e holimo bakeng sa liindasteri tse sebetsang hantle. Tataisong ena, re tla manolla tsohle tseo o hlokang ho li tseba ka lelapa lena la alloy, ho tloha ho sebopeho, machining le ts'ebeliso.
7xxx Series Aluminium ke eng?
The7xxx letoto la motsoako oa aluminium ke oaho lelapa la alloy ea zinki-magnesium (joaloka 7075, 7050, 7475), e etselitsoeng lintho tse bonahalang tse matla haholo. Likarolo tsa mantlha li kenyelletsa:
Lisebelisoa tse ka sehloohong: zinki (5-8%) + magnesium + koporo.
Kalafo ea Mocheso: Limaraka tse ngata tse nang le kalafo ea mocheso (T6/T7 temper) bakeng sa ho tšoarella ho matlafalitsoeng.
Matla: Matla a thata ho fihla ho 570 MPa (ho feta litšepe tse ngata).
Tlhokomeliso: Khanyetso ea kutu e tlase hanyane ho feta 6 letoto la aluminium alloy (ts'ireletso ea ho roala).
7075 ke motsoako o tloaelehileng oa 7xxx series aluminium alloy, litšobotsi tse ka sehloohong ke matla a phahameng, ho hanyetsa mokhathala o babatsehang, tšebeliso e tloaelehileng ke foreimi ea lifofane, lisebelisoa tsa sesole, joalo-joalo.
Lebaka la ho khetha a7-letoto la aluminium alloy plate
Ultra-High Strength: E loketse likarolo tse jereng mojaro.
E bobebe: 1/3 boima ba tšepe.
Heat Resistance: E boloka thepa ho mocheso o phahameng.
Machinability: Ho fihlella mamello e tiileng ka lisebelisoa tse nepahetseng.
7 letoto la litsebo tsa ho lokisa poleiti ea aluminium alloy
Khetho ea lisebelisoa
Lisebelisoa tsa ho Seha: Lisebelisoa tsa Carbide kapa polycrystalline diamond (PCD).
Tool Geometry: Li-angles tse phahameng tsa rake (12°–15°) ho fokotsa mocheso.
Lubrication: Sebelisa se pholisang moholi ho fokotsa khohlano.
Likhothaletso tsa Lebelo & Phepelo
Ho sila: 800–1,200 SFM (maoto a holim'a metsi ka motsotso).
Ho cheka: 150-300 RPM ka ho phunya peck ho hlakola li-chips.
Qoba Puisano: Sireletsa lipoleiti tse nang le lisebelisoa tsa vacuum.
Tlhokomelo ea Post-Machining
Khatello ea Maikutlo: Likarolo tse ling tsa ho thibela ho loana.
Anodizing: Sebelisa anodizing ea Mofuta oa II kapa oa III bakeng sa tšireletso ea kutu.
Mathata le Litharollo Tse Tloaelehileng
Stress Corrosion Cracking:
Lebaka: Khatello e setseng + libaka tse mongobo.
Lokisa: Sebelisa bohale ba T73, sebelisa liaparo tse sireletsang.
Ho lla nakong ea likhoele:
Lebaka: Lintho tse ngata tsa zinc.
Lokisa: Sebelisa lipompo tse koahetsoeng; tlotsa ka oli e boima.
Top Likopo tsa7xxx Aluminium Plates
Aerospace: Mapheo a mapheo, lisebelisoa tsa ho lulisa.
Tšireletso: Likarolo tsa koloi ea lihlomo.
Lipapali: Liforeimi tsa libaesekele, thepa ea ho hloa.
Likoloi: Likarolo tsa enjene ea khatello e phahameng.
