Pamene mainjiniya afotokoza fakitale yopangira phula yotaya phula pazigawo zazitsulo zofunika kwambiri - ganizirani ma valve othamanga kwambiri a hydraulic, ma nozzles a pampu a cobalt, kapena zodzigudubuza za winch center shaft - sakungogula chigawo chimodzi. Akubetcherana pa kusasinthika kwazitsulo, kubwerezabwereza, komanso kulekerera ziro pazowonongeka zazing'ono. Tawonapo mapulojekiti ambiri akuyimitsidwa pachiwonetsero chifukwa choyambira sichimatha ± 0.05 mm panyumba ya AMS 5387 cobalt alloy - kapena choyipitsitsa, chopereka magawo otenthedwa ndi oxidation yambewu yopanda malipoti. Ichi ndichifukwa chake kulondola sikulinso malonda apa. Ndilo maziko.
Chifukwa chiyani "Factory Yotayika Yotaya Sera" Imatanthauza Zambiri Kungoponya Ndalama
Kutaya phula kwenikweni kumapitirira kuposa kuthira zitsulo zosungunuka mu zipolopolo za ceramic. Imafunika kuwongolera kusinthasintha kulikonse: chipukuta misozi cha sera, zowumitsa zipolopolo, kuchuluka kwa ng'anjo yamoto, mbiri yozizirira, ndi kuzungulira kwapambuyo kupsinjika. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachitira gawo lililonse la cobalt-nickel alloy ngati zitsulo - osati kupanga. Mwachitsanzo, ma nozzles opangidwa ndi T800 amafunikira kutentha kusanachedwe pa 1,120 ° C kwa maola 4 musanaponye, ndikutsatiridwa ndi kuziziritsa kwa mpweya woyendetsedwa bwino kuti mupewe mvula ya sigma. Lumpha sitepe imeneyo? Gawoli limadutsa kuyang'ana kowoneka koma limalephera kuyesa kuphulika pa bar 320. Tatsimikizira izi m'nyumba, pamagulu 17 opanga ma silinda a AMS 5387 amisonkhano yamapampu akunyanja.
Mlingo wa njira iyi umalekanitsa malo ogulitsira ku a fakitale yopangira phula yotaya phula yopangidwa kuti igwire ntchito. Malo athu ogwirizana ndi ISO amaphatikiza kupanga ndalama ndi makina a CNC amitundu yambiri komanso kutentha kwa vacuum - zonse pansi pa denga limodzi. Palibe ma handoffs. Palibe kusiyana kwa batch-to-batch kuchokera kwa ogulitsa ena. Pamene nyumba ya pampu ya pisitoni imafuna ndime zoziziritsa zamkati zomwe zimapangidwira ± 0.03 mm mutatha kuponyera, timachita pa khwekhwe lomwelo lotsimikiziridwa ndi CMM pomwe chipolopolocho chinatsanuliridwa.
Kumene Ma Generic Foundries Amalephera-ndi Precision Partners Amapereka
Ogula ena amaganiza kuti ma cobalt alloy castings ndi ofanana ngati akumana ndi ASTM F75 chemical specs. Koma chemistry yokha sichitsimikizira khalidwe la makina. Pulagi yopangidwa kuchokera ku T800 ikhoza kuwonetsa 950 MPa UTS-koma aloyi yemweyo, woponyedwa ndi njira yolimba yolimba, imatsikira ku 710 MPa ndikusweka ndikutsitsa mozungulira. Tayesa kusiyana kumeneku mobwerezabwereza pogwiritsa ntchito mipiringidzo yokhazikika yotengedwa mu zipolopolo zenizeni, osati makuponi oyesera.
Ichi ndichifukwa chake kutsatiridwa kwathu kwazinthu si zolemba - kumaphatikizidwa. Zambiri zonse za cobalt-nickel zopangira zimabwera ndi malipoti athunthu a mayeso a mphero, kusanthula kowoneka bwino, ndikutsimikizira kukula kwambewu. Timawona chemistry yomwe ikubwera motsutsana ndi ma spectrometer athu a OES tisanasungunuke. Ngati mpweya wa carbon udutsa 0.18-0.22%, timakana gululo-ngakhale wogulitsa atsimikizira kuti akutsatira. Chifukwa mumipando ya valve yopanikizika, 0.03% ya carbon yowonjezera imapanga ma brittle carbide network omwe amayambitsa ming'alu ya kutopa pa 12,000 PSI.
- AMS 5387 cobalt alloy zigawo zoyesedwa ku 35,000 psi hydrostatic pressure-zero leakage
- Zopangira zitsulo zosapanga dzimbiri zovomerezeka ku ASTM A743 Giredi CA15, zokhala ndi mphamvu za Charpy V-notch ≥35 J pa -40°C
- Kuponyedwa kwachitsulo chokhala ndi nodule ya graphite yotsimikiziridwa pa ASTM E2396 (palibe mtundu wa D flakes)
Kugwirizana Kwapadziko Lonse—Osati Kungopereka Magawo Okha
Wopereka katundu yemwe amatumiza nthawi yake koma sangathe kutanthauzira mawu a GD&T kapena kusintha kwa makulidwe a mbendera komwe kumayambitsa kung'ambika kotentha sikuthetsa vuto lanu. Timayika ndemanga ya uinjiniya mu gawo la mawu—osati monga bokosi lofufuzira, koma ngati mapu ogwirira ntchito limodzi. Kota yapitayi, tidapeza cholakwika cha 2.3 ° pamtundu wa 3D wamakasitomala wa chodzigudubuza cha winch center shaft. Machining akadafuna kutanthauzira kwa 5-axis ndi 0.12 mm chida chopatuka-chosakhazikika pa 8,000 RPM. M'malo mwake, tidapereka lingaliro laling'ono la geometry tweak ndikuyambiranso kuyerekezera kwamafuta. Zotsatira: 37% mofulumira kuzungulira nthawi, zero rework.
Sitikuyembekezera kuti PPAP iyambe kulamulira khalidwe. Zomwe zikubwera zimatsimikiziridwa. Mawonekedwe a phula amatsimikiziridwa ndi mawonekedwe a kuwala. Zipolopolo zimayesedwa pa X-ray porosity musanatope. Castings amayesedwa akupanga * asanapange * makina - chifukwa kuchotsa 4 mm ya katundu pamalo opanda kanthu kumangobisa cholakwikacho. Kuyang'anira komaliza kumaphatikizapo kuyezetsa kogwira ntchito: ma valve opanikizika amayendetsa maulendo 10,000 pa kukakamizidwa kosiyana; maziko a pampu atakwezedwa ku 3x torque yogwira ntchito. Lipoti lililonse limasindikizidwa nthawi, limasaina, ndikumangirizidwa ku nambala ya kutentha ndi ID.
Kusankha Fakitale Yanu Yotayika Yotaya Sera—Chimene Chimasuntha Singano
Ngati ntchito yanu ikufuna ma nozzles a cobalt alloy, ma pistoni ovala kwambiri, kapena zitsulo zosapanga dzimbiri zosakhazikika, funsani mafunso atatu musanasaine PO:
- Kodi angatsimikizire kuwongolera kwazitsulo - osati chemistry - pagulu lanu la alloy? Funsani malipoti a kukula kwa tirigu, zotsatira za mayeso a intergranular corrosion, ndi zithunzi za SEM zosweka kuchokera pazopanga zaposachedwa.
- Kodi amapangira makina m'nyumba - kapena amatulutsa miyeso yovuta? Kutsirizitsa kwapamwamba, kupanikizika kotsalira, ndi kusintha kwa microstructure kusintha pamene zigawo zikuyenda pakati pa zipangizo. Kuphatikizika koyima sikuli kophweka-ndi inshuwaransi yowoneka bwino.
- Kodi chimachitika ndi chiyani ngati chojambula chanu chili ndi mkangano pakupanga? Wothandizana naye weniweni amachiyika msanga, amapangira njira zina zochirikizidwa ndi data yofananira, ndikugawana kusanthula kwamachitidwe olephera - osati "tiyesa."
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito pamphambano zaukadaulo wakuya wa alloy, integrated process control, ndi engineering pragmatism. Timamanga mbali zomwe zimakhalabe - osati kungodutsa kuyendera. Ndipo timachita izi kwa makasitomala omwe amayesa kupambana mu nthawi, osati masiku otumizira.
