Mukufuna zitsulo zogwira ntchito - zachangu, zotsika mtengo, komanso zodalirika - osadzipereka ku zida zonse zopangira? A prototype mchenga kuponyera fakitale milatho kuti kusiyana. Koma sizinthu zonse zoyambira zomwe zimapereka liwiro, kulondola, kapena kukhulupirika kwazinthu pamathamanga otsika. Tawona makasitomala akuwononga masabata 3-6-ndi madola masauzande-kudikirira osewera omwe amafika ndi zida zankhondo, porosity, kapena zopatuka za GD&T zomwe amangopeza atapanga makina. Kukonza sikutumiza mwachangu. Ndiko kuphatikizika kokulirapo pakati pa mapangidwe opangira, kupanga nkhungu, ndi mayendedwe a metrology kuyambira tsiku loyamba.
Chifukwa Chake Kuponya Mchenga Kumapambanabe Ma Prototypes Oyambirira Azitsulo
Kuponyera mchenga siukadaulo wakale-ndiyo njira yolabadira, yotsika mtengo kwambiri yopita ku zigawo zachitsulo zokhala ndi mawonekedwe a ukonde pansi pa 100 kg. Mosiyana ndi kuponyera ndalama, imalumpha machitidwe a sera ndi zipolopolo za ceramic. Mosiyana ndi kuponyera kufa, imagwira ma aloyi a cobalt, zitsulo zosapanga dzimbiri, ndi zitsulo za silicon zapamwamba popanda mtengo woletsa kugwiritsa ntchito zida. Mtundu umodzi wogwiritsidwanso ntchito - CNC wopangidwa kuchokera ku aluminiyamu kapena matabwa opaka utomoni - umathandizira kutsanuliridwa kwa 5 mpaka 20. Nthawi yotsogolera imatsika mpaka masiku 10-18. Kusinthasintha kwa zinthu kumakhalabe pamwamba: ASTM A48 Class 30 imvi chitsulo, ASTM A197 malleable chitsulo, ASTM A27 LCC carbon steel, ngakhale AMS 5387 cobalt-nickel superalloy—zonse zotayidwa ndi kulimba molamulirika ndi pambuyo kuthira kutentha kutentha.
Koma kuthamanga sikukutanthauza kanthu ngati kuponyako kupotoza panthawi yozizirira kapena kulephera kutsimikizika pa siteshoni ya CMM. Ndiko kumene masitolo ambiri a "prototype" amalephera. Amawona kuponya mchenga ngati njira yodziyimira yokha-osati ngati node yoyamba pamndandanda wolondola. Tinayeza mpaka 0.8 mm wa shrinkage mosayembekezereka mu nkhungu za mchenga wobiriwira wosalamulirika wa nyumba za silinda zapampu. Chifukwa chake? Kuthamanga kosagwirizana ndi ramming, kusintha kwa chinyezi, komanso kusakhala ndi nthawi yeniyeni yowunikira. Kukonza komwe kumafuna mwambo wapansi-osati zongoyerekeza zamapulogalamu.
Zomwe Zimalekanitsa Factory Yeniyeni Yoponya Mchenga Kuchokera ku General Foundry
Odzipereka prototype mchenga kuponyera fakitale imagwira ntchito pansi pa zopinga zitatu zomwe sizingakambirane: kutsata, kubwereza, ndi kuyankha. Osati voliyumu. Osati mtengo wotsika kwambiri. Umu ndi momwe zimakhalira pakuchita:
- Kufufuza kwazinthu kumayambira pakusungunuka: Gulu lililonse limakhala ndi malipoti ovomerezeka a mphero (MTRs), zipika za ng'anjo, ndi kusanthula kowonekera. Palibe zolemba za "generic alloy". Pazigawo za T800 zokhala ndi cobalt, timatsimikizira zomwe zili mu cobalt mkati mwa ± 0.3%, chromium mkati ± 0.2%, ndi kaboni mkati ± 0.02% -osati kungotsatira AMS 5387, koma kusasinthika pakutsanulira.
- Dimensional control imayamba musanathire: Timagwiritsa ntchito sikani ya 3D pamtundu uliwonse ndi bokosi lapakati-osati kungojambula komaliza. Ngati chojambula cha pampu ya pisitoni chikuyitanitsa ± 0.15 mm polumikizana ndi bore, timatsimikizira kolowera kwapateni, mzere wolekanitsa, ndi malo osindikizira * mchenga usanadzaze.
- Ndemanga zimatsekeka m'maola, osati masiku: Makasitomala akatumiza chojambula cha GD&T-heavy valve body, gulu lathu la mainjiniya limabweza manotsi opangira manufacturability — kuphatikiza malingaliro a geting, kakhazikitsidwe ka chokwera chokwera, ndi machining stock allowances — mkati mwa maola 48 abizinesi. Palibe kuyembekezera alangizi akunja.
Ena anganene kuti kuponya mchenga sikungathe kulolerana mwamphamvu. Koma nthawi zonse timagwira ± 0.25 mm pazinthu zovuta monga mabwalo a flange bolt ndi ma shaft bores-ngakhale pa matupi a hydraulic valve 450 mm-pogwiritsa ntchito mchenga wopangidwa ndi utomoni wopangidwa ndi utomoni, kutsekemera kwa nkhungu yothandizidwa ndi vacuum, ndi mpumulo wa post-shakeout. Kusiyana si zamatsenga. Ndizolembedwa zolembedwa, zida zoyeserera, ndi mainjiniya omwe atulutsa magawo 12,000+ kuyambira 2015.
Zotulutsa Zenizeni Zapadziko Lonse: Zomwe Mumalandila
Mukamagwiritsa ntchito fakitale yeniyeni yopangira mchenga, simupeza ndalama zogulira komanso zonyamula. Mumapeza gawo lovomerezeka, lokonzekera makina - lokhala ndi zolemba zonse. Kutumiza kulikonse kumaphatikizapo:
- Lipoti losayinidwa losonyeza miyeso yoyezedwa ndi CMM motsutsana ndi zojambula zanu, yokhala ndi chiphaso chamitundu / cholephera pa chilichonse
- Zithunzi za malo oponyedwa - kuwonetsa porosity yaying'ono kapena kung'anima komwe kumagwera munjira yovomerezeka ya ASTM A601
- Zolemba zochizira kutentha (ngati zanenedwa), kuphatikiza nthawi yonyowa, kuchuluka kwa kutentha, ndi data yamlengalenga wa ng'anjo
- Chitsimikizo chazinthu chokhala ndi mankhwala athunthu komanso zotsatira zoyeserera zamakina (kulimba kwamphamvu, zokolola, kutalika, kuuma)
Izi sizowonjezera-injiniya. Ndi kuchepetsa chiopsezo. Pampu imodzi ya OEM yaku North America idapewa kukumbukira kumunda kwa $220,000 chifukwa makina athu ojambulidwa asanatumizidwe adagwira gawo laling'ono mumphuno la AMS 5387 - lowoneka kokha pakutsanuliridwa kwachitatu kwa gawo lawo la magawo asanu. Kuwunika kumeneku kumangogwira ntchito popanga, NDT, ndi metrology zimakhala pansi pa denga limodzi.
Njira Zina: Momwe Mungayambitsire Prototype Yanu Kuthamanga Kumanja
Yambani ndi kujambula kwanu-osati bajeti yanu. Titumizireni fayilo yanu ya STEP kapena IGES yokhala ndi ma callout a GD&T, zinthu zina, ndi zofunikira pakugwira ntchito (mwachitsanzo, "iyenera kusindikiza pa bar 350 popanda kupindika"). Tiyankha ndi lipoti latsatanetsatane la DFM, nthawi yotsogolera, ndi mawu otsimikiza - palibe kulembetsa, palibe ma NDA ofunikira. Malo athu ogwirizana ndi ISO ku Qingdao amathandizira magawo achitsulo otsika kwambiri kuchokera pa 2 kg mpaka 85 kg, okhala ndi makina a CNC, chithandizo cha kutentha, komanso kumaliza kwapamwamba komwe kuli m'nyumba. Ngati ntchito yanu ikufuna cobalt-nickel alloys, high-pressure integrity, kapena repeatable microstructure, yambani ndi kuwongolera-osati kunyengerera.
Kwa mainjiniya omanga ma hydraulic system, zida zamafuta & gasi, kapena zida zamagalimoto opangidwa, kumanja prototype mchenga kuponyera fakitale sizimangopanga magawo. Zimatsimikizira cholinga chanu - musanadule chida chanu choyamba chopangira.
