Pamene mainjiniya afotokoza mkulu mwatsatanetsatane magnesium aloyi kufa kuponyera fakitale, samangopempha wowagulira—amafuna kukhazikika kwapang'onopang'ono poyendetsa njinga yamoto, kufanana kwa microstructural kudera laling'ono lopyapyala, komanso kusagwirizana ndi mphamvu zokhazikika pamatenthedwe okwera a ntchito. Magnesium alloys monga AZ91D, AM60B, ndi WE43 amapereka mphamvu zosagwirizana ndi kulemera kwa thupi-koma pokhapokha ngati njira yoponyera imfa imayendetsa hydrogen porosity, kuchepetsa kufa kwa soldering, ndi kutseka ± 0.05 mm kulolerana pazinthu zazing'ono ngati 0.8 mm makulidwe a khoma. Kuwongolera koteroko sikumachitika muzinthu zoyambira.
Taponya nyumba zopitilira 12,000 WE43 zama magnesium zopangira ma hydraulic actuators-ndipo gulu lililonse ladutsa 100% kuwunika kwa X-ray popanda kuchepera. Chifukwa chiyani? Chifukwa kuponyedwa kolondola kwa magnesium sikukhudza makina akulu kapena nthawi yozungulira mwachangu. Ndi za kuyang'anira kutentha kosungunuka mkati mwa ± 3 ° C, kusunga kumapeto kwa Ra 0.4 μm, ndikugwiritsa ntchito kudzaza kothandizidwa ndi vacuum kupondereza filimu ya okusayidi. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sititenga magnesium ngati "aluminium yopepuka," koma ngati chitsulo chokhazikika, chanjala ya okosijeni chomwe chimafuna zida zodzipatulira, chitetezo cha inert-gas, komanso kuyang'anira nthawi yeniyeni ya kuthamanga kwa mpweya.
Zolephera zambiri zoponya ma magnesium zimabwereranso ku mipata itatu yomwe ingapeweke: kuwongolera kosasinthasintha kwambewu panthawi yolimba, kugawa kosalamulirika kwa gawo la intermetallic (makamaka Mg.17Al12), ndi kupotoza pambuyo poponya kuchokera pakupumula kotsalira kwa nkhawa. Timatseka mipatayi pophatikiza kuyerekezera ndi mapu enieni a in-die thermocouple-kenako kutsimikizira jiometri ya nkhungu iliyonse motsutsana ndi mipiringidzo ya ASTM B94-22 ndi kuyesa kwa mlingo wa ISO 11992-2. Zojambula zathu zamchenga za magnesium zimakwaniritsa Cpk ≥ 1.67 pamawu ofunikira a GD&T; kupanga kumayendera ± 0.03 mm pa coaxiality pakati pa mbombo ndi ma flanges okwera-popanda makina achiwiri.
Kuphatikiza koyima kumapangitsa kusiyana. Ngakhale mafakitale ambiri otchedwa "mwatsatanetsatane" amatulutsa chithandizo cha kutentha kapena CNC kumaliza, timayendetsa unyolo wonse: aloyi ya magnesium imasungunuka muzitsulo za graphite pansi pa SF.6/CO2 Gasi wophimba, kutentha kwa vacuum yayikulu pa 720-740 ° C kusungunuka kwa kutentha, njira ya T6 yolumikizira ndi mitengo yowongolera, ndikutsimikizira komaliza kwa CMM pogwiritsa ntchito Zeiss CONTURA G2 yokhala ndi scanning tactile. Izi zimachotsa zolakwika za mawonekedwe-palibe ma data olakwika pakati pa zoyambira ndi malo ogulitsira makina, palibe mbiri yobisika yamafuta yomwe imakhudza machinability. Pamene pampu ya ku Ulaya OEM inkafunika nyumba za magnesium cylinder ndi 0.1 mm flatness pa nkhope ya 220 mm ndi 300 MPa mphamvu zokolola, tinapereka magawo a nkhani yoyamba m'masiku 18-osati chifukwa tinathamanga, koma chifukwa mapu athu a ndondomeko anali ndi kuchedwa kwa zero handoff.
Zochitika zenizeni padziko lapansi ndizofunikira kwambiri kuposa mapepala enieni. Makasitomala m'modzi adanenanso kuti moyo wautali wautumiki wa 40% pa shaft roller ya magnesium winch center motsutsana ndi zofananira za aluminiyamu - pambuyo pa mizungu 12,000 pansi pa 85 kN radial load komanso kuwonetsa mchere wopopera. Chifukwa chiyani? Zoyika zathu za AMS 5387-zogwirizana za cobalt-nickel zomangika m'nyumba za magnesium zimasunga kuuma pamwamba pa 42 HRC pomwe aloyi yoyambira idatenga mphamvu yakunjenjemera. Kapangidwe ka haibridi kameneka kamagwira ntchito kokha pamene magulu opanga ndi opanga makina amagawana misonkhano yowunikiranso uinjiniya yemweyo-ndipo kutsatiridwa kwa zinthu kumalumikiza gawo lililonse kugawo lake loyambirira, chipika cha ng'anjo, ndi lipoti loyesa. Sitimangokumana ndi ISO 9001:2015-timayika ndemanga zowopsa zamtundu wa AS9100 muzoyambira zatsopano za magnesium.
Ngati mukufuna a mkulu mwatsatanetsatane magnesium aloyi kufa kuponyera fakitale zomwe zimawona magnesiamu ngati zida zaumisiri-osati choloweza m'malo mopepuka-mumafunikira kuwongolera, kuyankha kwazitsulo, komanso kulekerera zero pakungopeka. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imapereka zolimba pama hydraulic manifolds, maziko a pampu, ndi zida zamagalimoto zofunika kwambiri. Kulondola kumayambira pomwe kusungunuka kumakumana ndi kufa - ndipo kumakhala kotsekeredwa mpaka kuyesedwa komaliza.
