Kupanga mchenga kumakhalabe njira yotsika mtengo kwambiri yopangira zitsulo zovuta, zolimba kwambiri - makamaka pamene makulidwe a khoma amaposa 6 mm, kulemera kwake kumaposa 5 kg, kapena mavoti a pachaka amagwera pakati pa 10 ndi 500 mayunitsi. Koma sizinthu zonse zoponya mchenga zofanana. Tawona makasitomala ambiri akulandira ma castings osagwirizana ndi chimanga, porosity yosayembekezereka m'ma flanges onyamula katundu, kapena kutengeka pang'onopang'ono pambuyo pochiza kutentha-kungozindikira kuti chomwe chimayambitsa sichinali kutentha kwakuthupi kapena kutentha, koma kusiyanasiyana kwa nkhungu pazisindikizo zapakati.
Chifukwa Chake Kuponyera Mchenga Kumapambanabe Pazigawo Zolondola Zamakampani
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timayendetsa mchenga ndi mizere yopangira ndalama-koma timasungira mchenga kumadera omwe kutentha kwa matenthedwe, kusungunuka kwa makina, kapena ma geometry amafunikira: silinda yapampu ya piston imakhala ndi kutalika kwa 1,200 mm, injini ya galimoto yopangira winch pakati shaft rollers kulemera kwa 2 ma valve 2 kg2. Izi siziri "zopanda kanthu" zomwe zikuyembekezera makina olemera. Ndizojambula zowoneka ngati ukonde zomwe zimasungidwa ku ± 0.3 mm pamalo ofunikira kwambiri, zomaliza zolimba ngati Ra 6.3 µm pamakina opangidwa ndi makina.
Chinsinsi sichidumpha mwatsatanetsatane - ndikuyika kale. Njira yathu yopangira mchenga imayamba ndi zida zamakina a CNC (osati nkhuni kapena thovu), amagwiritsa ntchito mchenga wa silika wokhala ndi utomoni wokhala ndi chinyezi chowongolera. <2.1% ndi permeability 110-130, ndipo imagwiritsa ntchito nthawi yeniyeni yowunikira panthawi yomanga. Gawo lomaliza lokhalo limachepetsa zolakwika zazikulu ndi 74% poyerekeza ndi ramming pamanja - zomwe zatsimikiziridwa pamagulu 18 amtundu wa hydraulic pa Q3 2023.
zisankho Zinayi Zaukadaulo Zomwe Zimapanga Kapena Kuphwanya Kuyimba Kwanu
Zolephera zambiri zimayambira ku chimodzi mwa zosankha zinayi zomwe mchenga woyamba usanakhudze botolo:
- Njira yoperekera chitsanzo: Standard 1% shrink compensation imalephera kwa cobalt-nickel alloys monga AMS 5387. Timagwiritsa ntchito zovomerezeka zosiyana-0.92% axial, 0.85% radial-kwa nyumba zapampu za T800 kuti zigwire GD & T callouts pamabuku osindikizira.
- Riser design logic: Osatengera voliyumu, koma kulimbitsa-nthawi yofananira. Timatsanzira ma curve ozizira pogwiritsa ntchito MAGMAsoft, kenaka timayika zokwera zotchinga pokhapokha pomwe nthawi yokhazikika yakumalo imatsika pansi pa 87% ya gawo lokhuthala kwambiri.
- Kuyikapo mpweya wa nkhungu: Malo olowera mpweya amapita 12 mm kuchokera ku mizere yopatsirana/yogawanika—osati mwachisawawa—yomangika kuti athawe njira za gasi zojambulidwa kudzera pakuyesa kuvunda kwa vacuum.
- Nthawi ya Shakeout: Osati "pamene ozizira mokwanira kuti agwire." Popanga chitsulo cha ductile pamwamba pa makulidwe a 80 mm, timachedwetsa kugwedeza mpaka kutentha kwa pamwamba kugunda 520°C ±15°C. Patukani ndi kupitilira 20 ° C, ndikuwonjezera kupsinjika kotsalira 3.2 × pamapampu oyika maziko.
Pamene Kuponyera Mchenga Kumapambana Kuponya Ndalama-Ndipo Pamene Sichitero
Mainjiniya ena amalephera kupanga ndalama kuti "zolondola." Koma ndi msampha. Kuyika ndalama kumaposa 15 kg ndi pansi pa 150 mm max dimension - komabe kumavutika ndi ndime zamkati zazikulu kuposa Ø25 mm kapena kusintha kwakhoma kupitirira 45 mm popanda misozi yotentha. Posachedwa tayendetsanso dongosolo la nozzle ya cobalt: zinthu zomwezo za AMS 5387, kusindikiza komweko, njira ziwiri. Kuponya ndalama kumapereka zokolola za 92% - koma zimafunikira maola 11 a EDM kuyeretsa gawo lililonse kuti achotse zotsalira za ceramic kuchokera ku 320 mm mkati. Kuponya mchenga? 98% zokolola, zero post-cast bore kumaliza kumafunika, 37% kutsika mtengo wonse wofikira.
Komabe-kuponya mchenga kumalephera mwachangu mukafuna Ra ≤1.6 µm ngati malo oponyedwa, kapena mawonekedwe ang'onoang'ono kuposa Ø3 mm okhala ndi kuya mpaka m'mimba mwake> 4. Iwo amapita molunjika ku CNC Machining kuchokera ku bar yolimba. Sitikukakamiza-kugwirizana ndondomeko. Tsamba lathu logwira mawu limasonyezera kusamvana kumeneku, ndi njira zina zotsatiridwa ndi mtengo wonse pagawo lililonse - osati pa kilogalamu kapena pa ola.
Mmene Real-World Quality Control Imawonekera
"ISO-certified foundry" imatanthawuza pang'ono ngati kuyendera kuyimitsidwa pazitsulo zolimba. Pamalo athu a Qingdao, malo aliwonse opanga mchenga amakumana ndi malo anayi ovomerezeka:
- Kusanthula kwa batch yamchenga yomwe ikubwera: Kugawa kwa sieve, dongo ladothi, ndikuyatsa pa ASTM C1107.
- Kutsimikizira kuuma kwa nkhungu kusanathire: Kuwerenga kwa Shore Scleroscope ≥72 pamalo onse olimba, ojambulidwa pa malo oponyera.
- Post-shakeout akupanga kupanga sikani: 100% volumetric anayendera subsurface shrink pa zovuta zigawo-palibe zitsanzo.
- Chitsimikizo chomaliza cha CMM: Lipoti lathunthu la GD&T motsutsana ndi zojambula zoyambirira, kuphatikiza macheke amtundu wa datamu pambuyo pa chithandizo cha kutentha kwapang'onopang'ono.
Timasunga kutsata kwathunthu: manambala amchenga, zipika za ng'anjo yosungunula, mamapu akulimba kwa nkhungu, ndi mitambo ya CMM—zonsezo zikugwirizana ndi nambala yanu ya PO. Palibe kuchotserapo. Umu ndi momwe timatsimikizira kuti ma valve opanikizika amakwaniritsa zofunikira za API 6D pamakontrakitala atatu aku North America othandizira - popanda kulephera kumodzi m'miyezi 22.
Mwakonzeka Konzani Kuyimba Kwanu Kotsatira?
Ngati gawo lanu likulemera 8-300 kg, limagwira ntchito movutikira kapena movutikira, ndipo limafuna kusasinthika kwazitsulo pamagulu onse - kupanga mchenga si njira yanu yobwerera. Ndiwochulukitsira machitidwe anu. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amamanga ma castings omwe amapulumuka-osati kungopambana-kuyesa koyenerera. Timayamba ndi cholinga chanu chogwira ntchito, osati zojambula zanu. Kenako timafananiza njira, zinthu, komanso kuwunikira zomwe pulogalamuyo ikufuna - osati zomwe bukuli likunena kuti ndizotheka.
Pitani ku https://www.tsingtaocnc.com kuti mupemphe kuunikako kopanga. Bweretsani GD&T yanu, malo ogwirira ntchito, ndi mbiri yolephera. Tikuwuzani zomwe ziyenera kuponyedwa, zomwe ziyenera kupangidwa ndi makina, komanso komwe kupanga mchenga kumapereka ROI yoyezera, musanadule mtundu umodzi.
