Xa usiva 'i-aero investment casting', umfanekiso ongoko nangoko uhlala ungenasiphako, iiblade ze-injini ye-injini yejethi. Akulunganga oko, kodwa yimbono emxinwa ngokuyingozi. Ngokwenyani, kuninzi malunga nokulawula iinyani zesiqhelo zeepateni ze-wax, i-ceramic slurry viscosity, kunye nokungahambi kakuhle kolwandiso lwe-thermal njengoko imalunga nozuko lwe-aerospace. Umngxunya oqhelekileyo woshishino kukuthembisa ngokugqithisileyo unyamezelo kwizibiyeli ezinodonga olucekethekileyo lwesakhiwo ngenxa nje yokuba ikukujula kwe-aerospace – inkqubo ayingomlingo. Litsheyini lamanyathelo alawulwa ngobuchule, kwaye ikhonkco elibuthathaka naphi na, ukusuka kuyilo lokuqala lokungunda ukuya kunyango lokugqibela lobushushu, liya kumisa inxalenye ngokukhawuleza kunokuba unokuthi ukusilela kwe-NDT.
I-Core Illusion: Ukuchaneka akubonelelwanga
Iimpawu ezininzi zokuthenga ezivela kwiinjineli zoyilo zithatha utyalo-mali njengembumbulu yesilivere ekufutshane. Baza kuyila indlu ye-aluminiyam entsonkothileyo enetshaneli zangaphakathi, bachaze i-±0.005 njengonyamezelo lokuphosa ngapha kwe-15-intshi yedimension, kwaye uyilindele ngqo ngaphandle kweqokobhe. Leyo yiresiphi yokuphoxeka kunye nokugqithiswa kweendleko. Inyaniso kukuba, i i-aero investment casting inkqubo yazisa ngokwendalo iinguqu. Isigaba sokutofa kwe-wax sisodwa - ubushushu, uxinzelelo, ixesha lokuhlala - kunokubangela ukuphazamiseka kwepateni okubonakala kuphela emva kokwakhiwa kweqokobhe leceramic. Ndikhe ndabona ibhetshi yezindlu ze-actuator apho i-flange flat iphumile ngenxa yokuba iqondo lobushushu legumbi le-wax liye laguquguquka ngaphezulu kwe-5 ° C kuloo veki. Ukuchaneka kuyazuzwa, akucingelwa.
Kulapho ubambiswano kunye ne-Foundry luba lubaluleke kakhulu. Ayikokuthumela nje imodeli yeCAD kwaye ilindile. Ivenkile efana neQingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye neminyaka engamashumi amathathu kwiqokobhe kunye nokuphosa utyalo-mali, ngokukhawuleza iya kujonga indawo yokuqhelaniswa emthini, uyilo lokungena, kunye neendawo ezinokuthi zishushu. Amava abo ngentsimbi kunye ne-nickel-based alloys athetha ukuba bacinga malunga nokuqiniswa kweepateni zokunciphisa ukusuka ekuqaleni. Isiseko esihle asicaphuli nje; benza uhlalutyo lokwenziwa kwezinto oluhlala lubandakanya ukucebisa ukuguqulwa kwedrafti efihlakeleyo okanye ukucebisa utshintsho ukusuka kwi-17-4PH engenastainless ukuya kwibakala elahlukileyo intsimbi engenasici eziphatha ngcono ngexesha lenkqubo yotyalo-mali yaloo geometry ethile.
Utyalo-mali egameni alukho nje malunga neqokobhe leceramic elibingelwayo. Lutyalo-mali kwimveliso ephindaphindiweyo.
