Mainjiniya akamatchula magawo a mapampu a hydraulic, mavavu akumunda wamafuta, kapena makina owinda olemera kwambiri, samangofunika chitsulo - amafunikira kutsimikizika kokulirapo. Kupatuka kwa 0.02 mm pampando wa nozzle wa cobalt-aloyi kumatha kuyambitsa cavitation. Kulumikizana molakwika kwa 0.05 mm mu nyumba ya silinda ya pampu ya pistoni kumatha kufulumizitsa kuvala ndi 40%. Ichi ndichifukwa chake otsogolera ma OEMs ndi ogulitsa Tier-1 nthawi zonse amabwerera ku a fakitale yoponyera phula yolondola kwambiri chimene chimaona kulolerana osati monga chandamale—koma monga maziko.
Chifukwa Chake Investment Casting Imapambanabe Pomwe CNC Yokha Imalephera
Tawona ma projekiti ambiri akuyimitsidwa pachiwonetsero chifukwa opanga amaganiza kuti makina amitundu ingapo amatha kuthana ndi ma geometri ovuta amkati-monga ndime zoyenda mkati mwa nyumba zapampu za AMS 5387 kapena njira zoziziritsa zocheperako m'matupi a valve a T800. CNC imagwira ntchito bwino pazinthu zakunja. Koma makulidwe a khoma akatsika pansi pa 2.5 mm, radii yamkati imachepa mpaka R0.3, ndipo umphumphu wazitsulo uyenera kupulumuka 350 ° C panjinga yotentha? Ndipamene kuponyera sera yotayika kumapereka zomwe mphero singathe: zovuta zaukonde popanda kusokoneza kapangidwe ka tirigu.
Pamalo athu ku Qingdao, chigawo chilichonse cha faifi tambala wa cobalt chimayamba ndi mawonekedwe a sera opangidwa kuchokera ku data yotsimikizika ya CAD-osati mafayilo a STL pafupifupi. Timagwiritsa ntchito vacuum-assisted ceramic shell dipping, controlled dewaxing pa 120 ° C, ndi ng'anjo preheat ku 1,050 ° C pamaso kuthira. Izi zimachotsa ma micro-shrinkage voids omwe amapezeka m'malo opangira mchenga. Chotsatira? Kutsirizira kwapamwamba kwa Ra 3.2 µm, kulolerana kwa mzere wa ± 0.05 mm mpaka 200 mm, ndi kutsata kwathunthu ISO 8062-2:2013 pakulekerera magawo.
Kuphatikiza Koyima Si Buzzword-Ndi Inshuwaransi Yanu Yamagawo
Opanga ena amatumiza zoponya m'mashopu ena kuti azipanga makina. Izi zimabweretsa mitundu itatu yosalamulirika: kupotoza kwamafuta panthawi yamayendedwe, kufotokozera mosagwirizana ndi ma data, komanso kuchedwetsa kuyankha pomwe kuyimba kwa GD&T kumakangana ndi geometry ya as-cast. Timapewa zonsezi pogwira kuponyera, kutentha kutentha, ndikumaliza pansi pa denga limodzi - komanso pansi pa dongosolo limodzi labwino.
Maselo athu a CNC amayendetsa nthawi imodzi 5-axis mphero ndikutsimikizira kwa CMM pamtundu uliwonse wa valve. Makasitomala akatumiza chojambula chololera bwino cha Ø0.03 mm pamabowo asanu ndi limodzi a bawuti okhudzana ndi datum yomwe idakhazikitsidwa pamipanda yopyapyala yopangidwa ndi mipanda yopyapyala - timapanga makina, kuyeza, kusintha, ndi kuyezanso - zonse pakusintha kumodzi. Palibe ma handoffs. Palibe kugawanika kwamagulu. Palibe mipata ya traceability. Chigawo chilichonse chimakhala ndi ziphaso zathunthu, zipika zochizira kutentha, ndikugwirizanitsa malipoti osungidwa kwa zaka 10.
Kuphatikiza uku kumafunika kwambiri ndi ma superalloys. T800 cobalt-based material amaumitsa mosayembekezereka pambuyo annealing yankho. Ngati machining achitika asanakalamba, kupsinjika kotsalira kumagawikanso ndikumangirira malo osindikizira ovuta. Njira yathu imatseka motsatana: kuponya → kuchepetsa nkhawa → makina → zaka → kuwunika komaliza. Tachepetsa kukonzanso pambuyo pa kutentha kwa zigawo za AMS 5387 kuchokera ku 11% mpaka 0.8% m'miyezi 24 yapitayi-chifukwa timalamulira unyolo wonse.
Zochitika Zenizeni Zapadziko Lonse Zimayamba Ndi Kuwongolera Zinthu Zowona Padziko Lonse
"Zinthu zotsimikizika" sizitanthauza pang'ono ngati lipoti la mayeso a mphero silikufanana ndi tag ya ingot-kapena ngati tsankho la aloyi silinadziwike pakuthira koyamba kwa 50 mm. Timatulutsa ma aloyi a cobalt-nickel kuchokera ku mphero zotsimikizika kupita ku ASTM B575 ndi AMS 5387 Rev. D. Kutentha kulikonse kumadutsa spark emission spectroscopy tikalandira. Malo aliwonse oponya amapeza kutsimikizika kwa PMI * asanamangidwe * ndi zipolopolo, komanso pambuyo popanga.
Timasunganso mgwirizano waukadaulo ndi ogulitsa awiri oyamba a cobalt - m'modzi ku Europe, wina ku North America - kuti agwirizane kupanga magawo opangira kutentha. Mwachitsanzo: tikamaponya ma nozzles a T800 pamapampu othamanga kwambiri, timasintha kuchuluka kwa kulimba ndi nthawi yoziziritsa nkhungu kutengera zomwe zili mu kaboni ndi silikoni wakutenthako, osati ma generic specs. Umu ndi momwe timakwaniritsira kuuma kosasinthika kwa 42-45 HRC kudutsa 98% yazopanga, osati zitsanzo za labu chabe.
Makasitomala nthawi zambiri amafunsa kuti: "Kodi mutha kukhala ndi ± 0.025 mm pamimba ya 120 mm yomwe ili mu T800?" Inde—ngati chojambuliracho chili ndi dongosolo la datum, chimafotokoza zofunikira za kukhulupirika pamwamba (osati kuuma kokha), ndipo chimatilola kutsimikizira kayesedwe ka zida polimbana ndi malipiro a katundu. Tikuwuzani zam'tsogolo ngati n'kotheka. Kapena komwe mungasinthe.
Kusankha Fakitale Yotaya Sera Yotayika Kumatanthauza Kusankha Mbiri Yanu Yangozi
Ogulitsa otsika mtengo amapikisana pamtengo pa kilogalamu. A zoona fakitale yoponyera phula yolondola kwambiri amapikisana pa kupewa kulephera. Pulagi iliyonse ya cobalt alloy yomwe timapereka imakhala ndi traceability yonse—kuchokera pa nambala ya kutentha kupita ku data yomaliza yoyeserera. Makina aliwonse opangira ma winch shaft amanyamula malipoti owoneka bwino omwe amasainidwa ndi oyang'anira athu ovomerezeka ndi ASQ. Dongosolo lililonse limaphatikizapo mayankho achangu opangira -osati "titha kupanga," koma "nayi momwe mungachepetsere mtengo ndi 22% popanda kusiya kukakamizidwa kwambiri."
Chilango chimenecho ndichifukwa chake chiwongolero chathu chobwereza chikupitilira 76% kudutsa North America, Europe, ndi Southeast Asia. Osati chifukwa ndife otsika mtengo. Chifukwa pamene msonkhano wanu wapampu ukuyenda pa 4,000 psi kwa maola 18,000, palibe "zabwino zokwanira." Pali ntchito zotsimikiziridwa zokha-ndi fakitale yomwe imayima kumbuyo kwake.
