7075 T652 Forged Aluminiyamu Bar Chiyambi Chathunthu cha Kapangidwe, Katundu ndi Ntchito

Mu mafakitale apamwamba opanga zinthu komanso mainjiniya olondola, aluminiyamu akhala zinthu zosasinthika chifukwa cha mawonekedwe awo opepuka komanso amphamvu kwambiri. Pakati pawo,7075 T652 bala ya aluminiyamu yopangidwaImadziwika bwino ngati chinthu chapamwamba kwambiri cha aluminiyamu champhamvu kwambiri, chomwe chili m'gulu la Al-Zn-Mg-Cu la aluminiyamu yamphamvu kwambiri. Imadziwika kwambiri mu ndege, zida zankhondo, makina olondola komanso mafakitale ena omwe amafunidwa kwambiri chifukwa cha mphamvu zake zapamwamba zamakanika komanso kukhazikika kwake.

Kapangidwe ka Mankhwala a 7075 T652 Forged Aluminiyamu Bar

Kugwira ntchito bwino kwa 7075 T652 forged aluminiyamu bar kumatsimikiziridwa ndi chiŵerengero chake cholondola cha mankhwala, chomwe chimagwirizana ndi miyezo yapadziko lonse lapansi monga ASTM B247, AMS 4140 ndi QQ-A-250/24. Zinthu zazikulu za mankhwala (mass fraction) ndi izi:

Aluminiyamu (Al) imakhala ndi 90.7% ~ 94.7%, yomwe imagwira ntchito ngati chinthu chopangira matrix kuti chitsimikizire kukana kopepuka komanso dzimbiri kwa aloyi.

Zinc (Zn) ndiye chinthu chachikulu cholimbitsa, chokhala ndi 5.1% ~ 6.1%, chomwe chimapanga chophatikiza champhamvu kwambiri chapakati pa zitsulo chokhala ndi magnesium ndi mkuwa kuti chiwongolere kwambiri mphamvu yokoka ndi kuuma kwa alloy.

Kuchuluka kwa magnesium (Mg) ndi 2.1% ~ 2.9%, komwe kumagwirizana ndi zinc kuti kulimbikitse kuuma kwa mvula ndikuwonjezera mphamvu ya alloy.

Kuchuluka kwa mkuwa (Cu) ndi 1.2% ~ 2.0%, zomwe zimapangitsa kuti aloyi ikhale yolimba komanso yolimba, komanso zimathandizira kuti isamavutike ndi dzimbiri.

Kuphatikiza apo, Chromium yochepa (Cr 0.18% ~ 0.28%) imawonjezedwa kuti isinthe kapangidwe ka tirigu, kuchotsa zolakwika zamkati, ndikuwonjezera kukana kutopa kwa alloy, ndikuwongolera mwamphamvu zinthu zodetsa monga chitsulo ndi silicon kuti zitsimikizire kuyera ndi kukhazikika kwa ntchito ya bar yopangidwa.

Cholumikizira ichi cholondola cha aluminiyamu chopangidwa ndi 7075 T652 chokhala ndi maziko olimba, kupewa zolakwika pakugwira ntchito chifukwa cha kuchuluka kwa zinthu zomwe zili mkati mwake, ndikuyika maziko olimba a mawonekedwe ake abwino kwambiri a makina komanso magwiridwe antchito ake.

Makhalidwe Abwino Kwambiri a 7075 T652 Forged Aluminiyamu Bar

Mpiringidzo wa aluminiyamu wopangidwa ndi 7075 T652 umakonzedwa pogwiritsa ntchito kupangira molondola, kuchiza kutentha kwa yankho, kuchepetsa kupsinjika ndi kukalamba kochita kupanga (T652 temper), zomwe zimagwirizanitsa bwino ubwino wa kupangira ndi kuchiza kutentha, kupereka zizindikiro zabwino kwambiri zogwirira ntchito zomwe zimakwaniritsa zosowa za opanga apamwamba.

Ponena za mphamvu zake zamakanika, ili ndi mphamvu yokoka kwambiri komanso mphamvu yotulutsa, yokhala ndi mphamvu yokoka mpaka 570~590 MPa ndi mphamvu yokoka ya 475~505 MPa, yofanana ndi chitsulo chapakati cha kaboni chomwe chili ndi gawo limodzi mwa magawo atatu okha a chitsulo, zomwe zimapangitsa kuti pakhale bwino pakati pa mphamvu yopepuka komanso yonyamula katundu. Kulimba kwake kwa Brinell kumafika 150~160 HB, yokhala ndi mphamvu yolimba yoteteza komanso yoletsa kusokonekera, yoyenera kupanga zida zonyamula katundu wambiri. Pakadali pano, T652 imagwiritsa ntchito 1%-5% yochepetsera kupsinjika pambuyo pokonza yankho, ndikuchotsa kwathunthu kupsinjika kwamkati komwe kumachitika mu njira yopangira ndi kutentha, ndikuwonetsetsa kuti kukhazikika kwabwino kwambiri panthawi yopangira ndi kugwiritsa ntchito nthawi yayitali, kupewa kupindika, kusintha ndi kupotoka kwa kukula, komwe ndikofunikira kwambiri pazigawo zogwirira ntchito molondola.

Ponena za kusinthasintha kwa chilengedwe, ili ndi mphamvu yabwino yotopa komanso kulimba kwamphamvu, imatha kupirira katundu wobwerezabwereza komanso kugwedezeka nthawi yomweyo popanda kusweka, yoyenera kugwiritsidwa ntchito kwa nthawi yayitali m'mikhalidwe yovuta yogwirira ntchito. Ngakhale kuti kukana kwake dzimbiri konse kuli kofooka kuposa kwa ma alloy a aluminiyamu 5000, njira zoyenera zochizira pamwamba monga anodizing ndi kupaka utoto zimatha kukulitsa bwino kukana kwake dzimbiri, ndikukulitsa kuchuluka kwa momwe imagwiritsidwira ntchito. Ilinso ndi makina abwino, imatha kusintha kutembenuza, kugaya, kubowola ndi njira zina zochizira molondola, ndipo ndi yosavuta kupanga zigawo zovuta, kukwaniritsa zofunikira kwambiri zochizira zida zapamwamba.

Kuchuluka kwa Ntchito ya 7075 T652 Forged Aluminiyamu Bar

Kudalira ubwino wake wonse wa magwiridwe antchito,7075 T652 bala ya aluminiyamu yopangidwaimagwiritsidwa ntchito kwambiri m'magawo omwe ali ndi zofunikira kwambiri kuti zinthu zikhale zolimba, zopepuka komanso zokhazikika, zomwe zimaphatikizapo mafakitale ambiri opanga zinthu kunyumba ndi kunja.

Mu makampani opanga ndege, ndi chinthu chomwe chimakonda kwambiri popanga zinthu zofunika kwambiri, zomwe zimagwiritsidwa ntchito popanga mapiko a ndege, ma fuselage frames, zida zolandirira ndege, zida zomangira ndege za satellite ndi zida zonyamula katundu wa roketi. Mphamvu zake zambiri komanso zopepuka zimachepetsa kulemera kwa zida zoyendera ndege, zimawonjezera mphamvu zonyamula katundu komanso kugwiritsa ntchito bwino mafuta, ndikuwonetsetsa kuti zidazo zili ndi chitetezo komanso kukhazikika bwino pamene zikugwira ntchito molimbika.

Mu gulu lankhondo ndi chitetezo, imagwiritsidwa ntchito kwambiri popanga chassis yamagalimoto ankhondo, zida zogwiritsira ntchito zida, zipolopolo za zida zolondola komanso zida zodzitetezera. Kulimba kwake kwakukulu komanso mphamvu zake zonyamula katundu zimaonetsetsa kuti zida zankhondo zikhale zodalirika komanso zolimba m'malo ovuta ankhondo, zomwe zimakwaniritsa miyezo yokhwima yopangira zida zankhondo.

Mu makampani opanga makina olondola komanso nkhungu, imagwiritsidwa ntchito pokonza ma shaft amakina olondola kwambiri, zida zogwiritsira ntchito, zoyika nkhungu ndi zida zodzipangira zokha. Kukhazikika kwake kwakukulu komanso kuthekera kwake kogwiritsa ntchito makina kumatsimikizira kulondola kwa makina ndi moyo wautumiki wa ziwalo, kuchepetsa kuchuluka kwa zinyalala zomwe zimachitika chifukwa cha kusintha kwa zinthu.

Kuphatikiza apo, imagwiritsidwanso ntchito m'zigawo zamagalimoto zogwira ntchito bwino, zida zothamanga, zida zamasewera zapamwamba (monga mafelemu a njinga, zida zokwera mapiri) ndi zida zolondola zam'madzi, zomwe zimapangitsa kuti zikhale zabwino kwambiri chifukwa cha mphamvu zake zapamwamba, zopepuka komanso zotsutsana ndi dzimbiri pambuyo pokonza pamwamba, kukwaniritsa zosowa zapamwamba zamafakitale osiyanasiyana.

7075 T652 forged aluminiyamu bar ndi chinthu cha aluminiyamu chopangidwa bwino kwambiri chomwe chili ndi mawonekedwe abwino kwambiri, ndipo kapangidwe kake ka mankhwala apadera komanso njira yapadera yochizira kutentha zimapangitsa kuti ikhale ndi zabwino zosayerekezeka pakugwiritsa ntchito mwamphamvu kwambiri, molondola kwambiri komanso mopepuka. Monga ogulitsa akatswiri pazinthu za aluminiyamu, timapereka mipiringidzo ya aluminiyamu yopangidwa ndi 7075 T652 yokhala ndi zofunikira zonse, magwiridwe antchito okhazikika komanso kutsatira miyezo yapadziko lonse lapansi, kuthandizira ntchito zokonzedwa mwamakonda komanso zogwirira ntchito molondola. Kaya mukugwira ntchito yopanga ndege, kupanga zida zankhondo kapena kukonza makina molondola, athu7075 T652 mipiringidzo ya aluminiyamu yopangidwa ndi chitsuloakhoza kukwaniritsa zofunikira zanu zokhwima, kukuthandizani kukonza khalidwe la malonda ndi mpikisano pamsika. Takulandirani kuti mulumikizane nafe kuti mupeze magawo atsatanetsatane a malonda, mawu ofotokozera ndi mayankho osinthidwa.
