Akatswiri akamatchula zigawo za cobalt-nickel alloy pamapampu a hydraulic, ma valve othamanga kwambiri, kapena makina owongolera akunyanja, funso limodzi limawonekera mobwerezabwereza: Kodi magawo a fakitale a Co 4 omwe amalolera pansi pa 0.01 mm mumawapeza kuti, ndikukhalabe ndi moyo maola 20,000+ muntchito yowononga, yovala kwambiri? Sikuti ogulitsa onse amagwira AMS 5387 cobalt alloy kapena T800-based castings ndi zitsulo zofunikira. Tawonapo ma prototypes akulephera kutsimikiziridwa chifukwa kutsatiridwa kwa zinthu zambiri kunalibe. Tawona kuchedwa kwapang'onopang'ono pomwe kutsitsa sikunalipidwe panthawi ya pulogalamu ya CNC. Ichi ndichifukwa chake ogula mwatsatanetsatane akulambalala oyimira malonda ndikupita mwachindunji kwa opanga omwe amawongolera kusungunuka kwa aloyi ndi makina omaliza a contour-monga QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Kuthekera kwa fakitale ya Co 4 kumayamba ndi umwini wazitsulo-osati makina okha
Otsatsa ambiri amadzitcha "akatswiri a aloyi a cobalt" koma amatumiza kunja kwa omwe adayambitsa chipani chachitatu. Izi zimapanga kusiyana kwakukulu: palibe kuwongolera kapangidwe ka tirigu, kagawidwe ka carbide, kapena tsankho la interdendritic. Ku QINGDAO QIANGSENYUAN, kayendedwe ka fakitale ya Co 4 imayamba ndi magulu ovomerezeka azinthu zopangira - AMS 5387 ingots zotsimikiziridwa ndi malipoti oyesa mphero ndi kusanthula kwa spectrometric musanathire. Mchenga wawo ndi mizere yopangira ndalama zimayenda pansi pazambiri zotentha, zotsatiridwa nthawi yomweyo ndi kuziziritsa ndi kuziziritsa koyendetsedwa pa ASTM A995. N’chifukwa chiyani zimenezi zili zofunika? Chifukwa nyumba za silinda za pampu ya pistoni sizimalephera kuchokera kumapeto - koma kuyambira pakuyambika kwa microcrack m'malire ofooka apakati omwe amapangidwa pakukhazikika kosalamulirika. Kuphatikizika kwawo koyima kumatanthawuza kuponya magawo, kuwongolera kutentha, ndi njira zamitundu yambiri za CNC zimakonzedwa ngati dongosolo limodzi-osati masitepe atatu osalumikizidwa.
Zochitika zenizeni zapadziko lonse lapansi zimadalira kukhazikika kwapang'onopang'ono pamagawo azinthu
Tidawunikanso phukusi la kasitomala la GD&T la cobalt alloy nozzle Assembly: ma callout enieni a ± 0.005 mm pamabowo asanu ndi limodzi a coaxial, roughness Ra ≤ 0.4 µm pankhope zosindikiza, ndi kuuma 42-46 HRC pambuyo pokalamba komaliza. Gawolo lidadutsa kuwunika kwa CMM pambuyo popanga makina - koma zidalephera kuyesa pambuyo pa maola 72 akupopera mchere. Choyambitsa? Kuchepetsa kupsinjika kotsalira sikunatsatidwe pakati pa roughing ndi kumaliza kudula. Fakitale ya QINGDAO QIANGSENYUAN's Co 4 imayika *kuchepetsa kupsinjika *pakati pa* ntchito zamakina, osati kumapeto kokha. Amagwiritsa ntchito chitsimikiziro cha CMM pazitsulo zolimba (osati aluminiyamu), amatsata kusuntha kwa kutentha pa ola lililonse, ndikugwiritsa ntchito njira zolipirira zosinthidwa pamakina awo enieni a Haas ndi DMG MORI. Zotsatira: matupi a valve opanikizika nthawi zonse amakwaniritsa 0.008 mm kutalika konse kwa 300 mm - ngakhale atadutsa komaliza.
Sizinthu zonse za cobalt zomwe zili zofanana-kalasi yazinthu imatanthauzira malire ogwiritsira ntchito
- AMS 5387 cobalt aloyi 6: Amagwiritsidwa ntchito pomwe kukana kukokoloka kumaposa mphamvu zokhazikika - lingalirani zamafuta a injini ya jet kapena mipando ya valve ya pansi pa nyanja. Kutentha kwakukulu kosalekeza: 815°C.
- T800 cobalt-based alloy: Yasankhidwa kuti ikhale ndi zida zonyamula katundu ngati zodzigudubuza za winch center shaft. Mafuta a faifi okwera kwambiri amathandizira kutopa kwapang'onopang'ono - koma kumafunikira chakudya chapang'onopang'ono cha makina ndi kukonza mokhazikika.
- Ma geometries osakhala wamba: Akatswiri awo samangotengera zojambula. Amawonetsa zigawo za khoma zopyapyala zomwe zimasokonekera panthawi yozimitsa, zikuwonetsa ma angles ochotsa zipolopolo, ndikutsimikizira makulidwe a khoma motsutsana ndi data yofananira.
Ichi si chidziwitso chabodza. Imamangidwa kuchokera ku nyumba 127 zolembedwa zapampu zomangira ma OEM aku Europe-ndi kusanthula 43 kulephera kwa zida za cobalt zomwe zabwezedwa m'munda. Wofuna chithandizo akafunsa pulagi yokhazikika yokhala ndi mayendedwe ozizirira mkati, sanatchule mawu ambiri. Adayendetsa FEA yotentha, adakonza njira yosinthidwa ya HIP kuti athetse porosity m'makoma a mayendedwe, ndipo adapereka zitsanzo zoyambirira m'masiku 18 - osati masabata asanu ndi atatu.
Kupeza mwachindunji kumapereka zodziwikiratu - osati mtengo wokha
Magulu ogula zinthu nthawi zambiri amaganiza kuti "factory mwachindunji" amatanthauza mtengo wotsika. Koma ubwino weniweni ndi kulamulira. Ndi QINGDAO QIANGSENYUAN, kuwunika kwa uinjiniya kumachitika ndi metallurgist yemweyo yemwe adasaina pa kutentha komaliza kwa AMS 5387. Ziphaso zakuthupi zimaphatikizapo mbiri ya kutentha - osati chemistry yomaliza. Chilichonse chomwe chimatumizidwa chimakhala ndi kuchuluka kwa batch: nambala yosungunuka, tsiku loponyedwa, ID ya ng'anjo yotentha, ndi seriyoni ya lipoti la CMM. Palibe ma subkontrakta amtundu wakuda. Palibe zolipiritsa kukonzanso kodabwitsa kwa NDT yosakonzekera. Pakuti North America makasitomala, kutsogolera nthawi sing'anga buku malamulo (50-500 ma PC) pafupifupi 6-8 milungu-kuphatikizapo zonse dimensional, kuuma, ndi akupanga anayendera. Kusintha kwa Prototype? Kuthamanga kwa masiku 11 ogwira ntchito-ndi zolemba zonse za FAI zogwirizana ndi AS9102.
Kuyang'ana m'tsogolo, kuwunika kwa fakitale ya Co 4 kumakhalabe kocheperako komanso kozama: kuwongolera njira zosakanizidwa komwe kuyika ndalama kumakumana ndi 5-axis mphero, kukulitsa certification ya EN 10204 3.2, ndikutsimikizira mitundu yatsopano ya cobalt ya ntchito ya haidrojeni. Ngati projekiti yanu yotsatira ikufuna magawo omwe samangokumana ndi zenizeni - koma pitilizani ntchito pomwe ena amanyozeka - yambitsani ndi zokambirana zaukadaulo, osati pempho la mawu. Kulondola mu cobalt sikupangidwa. Zimapangidwa, kutsimikiziridwa, ndi kubwerezedwa.
