7xxx Series Aluminium Plates: Properties, Applications & Machining Guide

Amapuleti e-7xxx ochungechunge lwe-aluminium aziwa ngokwesilinganiso sawo esikhethekile samandla nesisindo, okuwenza abe yinketho ephezulu ezimbonini ezisebenza kahle kakhulu. Kulo mhlahlandlela, sizohlukanisa konke odinga ukukwazi mayelana nalo mndeni we-alloy, kusukela ekubunjweni, ukukhanda kanye nokusetshenziswa.

Iyini i-7xxx Series Aluminium?

IIngxube ye-aluminium engu-7xxx iyingxenyeemndenini we-zinc-magnesium alloy (njenge-7075, 7050, 7475), eklanyelwe ngokukhethekile izinto ezibonakalayo ezinamandla amakhulu. Izici ezibalulekile zifaka:

Izithako eziyinhloko: i-zinc (5-8%) + i-magnesium + ithusi.

Ukwelashwa Kokushisa: Amabanga amaningi anokwelashwa kokushisa (i-T6/T7 temper) ukuze kuqiniswe ukuqina.

Amandla: Amandla aqinile afika ku-570 MPa (ngaphezu kwezinsimbi eziningi).

Qaphela: Ukumelana nokugqwala kungaphansi kancane kune-6 series aluminium alloy (ukuvikela ukunamathela).

I-7075 iyingxubevange ye-7xxx evame kakhulu yochungechunge lwe-aluminium, izici eziyinhloko zingamandla aphezulu, ukumelana nokukhathala okuhle kakhulu, ukusetshenziswa okuvamile uhlaka lwezindiza, imishini yezempi, njll.

Isizathu sokukhetha aI-7-series aluminium alloy plate

Amandla Aphezulu Kakhulu: Ilungele izingxenye ezithwalayo.

I-Lightweight: 1/3 ukuminyana kwensimbi.

Ukumelana Nokushisa: Igcina izakhiwo emazingeni okushisa aphakeme.

Imishini: Ifinyelela ukubekezelelana okuqinile ngamathuluzi afanele.

Ukukhetha Ithuluzi

Amathuluzi Okusika: Amathuluzi e-Carbide noma e-polycrystalline diamond (PCD).

Ijiyomethri Yethuluzi: Ama-engeli amareki aphezulu (12°–15°) ukunciphisa ukushisa.

Ukuthambisa: Sebenzisa isibandisi senkungu ukuze unciphise ukungqubuzana.

Izincomo zokusheshisa nokuphakelayo

Ukugaya: 800–1,200 SFM (izinyawo ezingaphezulu ngomzuzu).

Ukubhoboza: 150–300 RPM nge-peck drilling ukususa ama-chips.

Gwema Ukuxoxa: Vikela amapuleti ngezinto ze-vacuum.

Ukunakekelwa Kwangemva Komshini

Ukunciphisa Ukucindezeleka: Izingxenye ze-Anneal ukuvimbela ukulwa.

I-anodizing: Faka i-anodizing yohlobo lwe-II noma lwe-III ukuze uvikele ukugqwala.

Izinselele Ezijwayelekile Nezixazululo

I-Stress Corrosion Cracking:

Imbangela: Izingcindezi eziyinsalela + izindawo ezinomswakama.

Lungisa: Sebenzisa i-T73 temper, sebenzisa izimbotshana zokuvikela.

Ukudla ngesikhathi sokukhulelwa:

Imbangela: Okuqukethwe okuphezulu kwe-zinc.

Lungisa: Sebenzisa ompompi ababoshiwe; gcoba ngamafutha asindayo.

Izinhlelo zokusebenza eziphezulu ze7xxx Aluminium Plates

I-Aerospace: I-Wing spars, igiya lokuhlala.

Ukuzivikela: Izingxenye zemoto yezikhali.

Ezemidlalo: Amafreyimu ebhayisikili, imishini yokukhuphuka.

Izimoto: Izingxenye zenjini ezinokucindezeleka okuphezulu.
