Investment casting, inozivikanwawo seyakarasika wax casting, yakagadzirwa makore 5,000 apfuura.Iyi nzira yekukanda inopa chaiyo, inodzokororwa uye inogoneka zvikamu zvine simbi dzakasiyana uye yakakwirira kuita alloys.Iyi nzira yekukanda inokodzera kukanda kunhuwa uye mativi echokwadi uye inodhura kupfuura dzimwe nzira dzekukanda.Nekugadzirwa kwakawanda, mutengo weyuniti uchadonha.
Investment casting process:
Wax Pateni Kugadzira: Vagadziri vekudyara mari vanofanirwa kugadzira mapatani ewakisi ekukanda kwavo wakisi.Mazhinji ekukanda maitirwo ekudyara anoda epamusoro ekukanda wax kuti apedze danho iri.
Wax tree assembly: Mutengo wekugadzira chigadzirwa chekudyara chimwe chete chakakwira, uye newax tree musangano, vagadziri vekudyara mari vanogona kugadzira goho rakawanda.
Kugadzira Shell: Gadzira masaga emateko pamiti yewakisi, woisimbisa uye woashandisa pakuita kukanda kunotevera.
Kubvisa wakisi: Kubvisa wakisi mukati kunopa mhango paunogona kudururira simbi yakanyunguduka muhombodo yapera.
Shell inodonha: Mushure mekunge simbi yakanyungudutswa yaoma, bvisa goko kuti utore muti wechigadzirwa chesimbi.Zvicheke kubva pamuti uye iwe uchave uine yekupedzisira investimendi yakakandwa chigadzirwa.
Technical features:
1. High dimensional accuracy uye geometric accuracy;
2. Kukasharara kwepamusoro;
3. Inogona kukanda makanda ane maumbirwo akaoma, uye alloys anokandwa haasi mashoma.
Kukanganisa: maitiro akaoma uye mari yakakwirira
Chishandiso: chakakodzera kugadzirwa kwezvikamu zvidiki zvine maumbirwo akaomarara, yakakwirira chaiyo zvinodiwa, kana yakaoma kuita kumwe kugadzirisa, senge turbine injini blades, nezvimwe.
1. Inogona kukanda makanda akaoma emhando dzakasiyana-siyana, kunyanya superalloy castings.Semuenzaniso, iyo yakakwenenzverwa yekunze mbiri uye inotonhorera yemukati mhango yeblade yejeti injini haigone kuumbwa nemaitiro ekugadzira.Kugadzirwa kwekudyara kwekudyara I tekinoroji haigone kungoita kugadzirwa kwakawanda, kuve nechokwadi kuenderana kwekukanda, asi zvakare kudzivirira kushushikana kweiyo yasara blade mitsetse mushure mekugadzira.
2. Kurongeka kwedimensional yeinvestment castings yakakwira, kazhinji kusvika kuCT4-6 (CT10~13 yekukanda jecha uye CT5~7 yekukanda kufa).Ehe, nekuda kwekuoma kweiyo investment casting process, pane zvakawanda zvinokanganisa kurongeka kwedimensional yekukanda, senge shrinkage ye mold material, deformation of the investment mold, linear change of mold shell panguva kupisa uye kutonhora maitiro, iyo shrinkage yegoridhe uye deformation yekukandira panguva yekusimbisa maitiro, iyo dimensional yekurongeka kweyakajairwa mari yekudyara yakakwira, zvisinei, kuwirirana kwayo kuchiri kufanira kuvandudzwa (iyo dimensional consistency yekukanda nepakati nepamusoro. tembiricha yakisi inofanira kuvandudzwa zvakanyanya)
3. Paunenge uchidzvanya iyo mold yekudyara, iyo mold ine yakakwirira yekumusoro kupera kweiyo mold cavity inoshandiswa.Naizvozvo, iyo yekumusoro kupedzisa kwekudyara mold zvakare yakakwira.Mukuwedzera, iyo mold shell inogadzirwa nemoto-inodzivirira coating yakagadzirwa nepamusoro-tembiricha inodzivirira inonamira uye inomira zvinhu, iyo yakavharwa pane yekudyara mold.Kupera kwepamusoro kwegomba rekuumbwa kwakanangana nekusangana nesimbi yakanyungudutswa kwakakwira.Nokudaro, kupera kwepamusoro kwekutsvaga kwekutsvaga kwekutsvaga kwekutsvaga kwakakwirira kudarika iyo yemitambo yakajairwa, kazhinji kusvika kuRa.1.3.2 μ m.
4. Mukana mukuru wekudyara kwekudyara ndeyekuti nekuti kukanda mari kune yakakwirira dimensional kurongeka uye kupera kwepasi, kunogona kuderedza basa rekugadzira.Ingori shoma shoma yekubvumidza machining inogona kusiiwa kune zvikamu zvine zvakakwirira zvinodikanwa, uye kunyangwe mamwe majekiseni anogona kushandiswa pasina mechaniki kugadzirisa.Zvinogona kuoneka kuti mari yekukanda nzira inogona kuchengetedza akawanda emuchina maturusi uye nguva yekugadzirisa, uye kuchengetedza zvakanyanya simbi mbishi zvinhu.
