Isahani ya 7xxx ya aluminiyumu izwiho imbaraga zidasanzwe-ku bipimo, bigatuma bahitamo neza inganda zikora neza. Muri iki gitabo, tuzasenya ibintu byose ukeneye kumenya kuri uyu muryango wavanze, uhereye kubihimbano, gutunganya no kubishyira mubikorwa.
Aluminium ya 7xxx ni iki?
Uwiteka7xxx ikurikirana ya aluminium alloy nikumuryango wa zinc-magnesium alloy (nka 7075, 7050, 7475), yabugenewe kubikoresho bifite imbaraga nyinshi. Ibintu by'ingenzi birimo:
Ibyingenzi byingenzi: zinc (5-8%) + magnesium + umuringa.
Kuvura Ubushyuhe: Ibyiciro byinshi hamwe no kuvura ubushyuhe (T6 / T7 ubushyuhe) kugirango birambe.
Imbaraga: Imbaraga zingana kugeza kuri MPa 570 (kurenza ibyuma byinshi).
Icyitonderwa: Kurwanya ruswa biri munsi gato ya 6 ya aluminiyumu (kurinda coating).
7075 ni 7xxx ikurikirana cyane ya aluminiyumu, ibintu nyamukuru biranga imbaraga nyinshi, kurwanya umunaniro mwiza, ikoreshwa rusange ni ikibuga cyindege, ibikoresho bya gisirikare, nibindi
Impamvu yo guhitamo a7-seri ya aluminiyumu
Ultra-High Imbaraga: Ideal kubintu bitwara imitwaro.
Umucyo woroshye: 1/3 ubwinshi bwibyuma.
Ubushyuhe bwo Kurwanya: Igumana imitungo ku bushyuhe bwo hejuru.
Imashini: Kugera kubyihanganirana hamwe nibikoresho bikwiye.
Urukurikirane 7 rwa aluminium alloy ubuhanga bwo gutunganya
Guhitamo ibikoresho
Ibikoresho byo gutema: ibikoresho bya Carbide cyangwa polycrystalline diamant (PCD).
Igikoresho Geometrie: Inguni ndende (12 ° –15 °) kugirango igabanye ubushyuhe.
Amavuta: Koresha ibicurane bikonje kugirango ugabanye guterana amagambo.
Umuvuduko & Kugaburira Ibyifuzo
Gusya: 800–1,200 SFM (ibirenge byo hejuru kumunota).
Gucukura: 150–300 RPM hamwe no gucukura peck kugirango ukureho chip.
Irinde kuganira: Isahani itekanye ifite ibikoresho bya vacuum.
Kwitaho nyuma yimashini
Kuruhuka Stress: Ibice bya Anneal kugirango wirinde kurwana.
Anodizing: Koresha Ubwoko bwa II cyangwa III anodizing kugirango wirinde ruswa.
Ibibazo rusange & Ibisubizo
Guhangayikishwa no Kwangirika:
Impamvu: Imyitwarire isigaye + ibidukikije.
Gukosora: Koresha ubushyuhe bwa T73, koresha impuzu zirinda.
Galling mugihe c'insanganyamatsiko:
Impamvu: Ibirimo byinshi bya zinc.
Gukosora: Koresha kanseri isize; gusiga amavuta aremereye.
Porogaramu yo hejuru ya7xxx Amasahani
Ikirere: Ibibaba by'ibaba, ibikoresho byo kugwa.
Ubwunganizi: Ibikoresho by'imodoka.
Imikino: Ikarita yamagare, ibikoresho byo kuzamuka.
Imodoka: Ibice bya moteri ikomeye.
