Ukubunjwa kwe-Foundry akukhona nje ukuthela insimbi encibilikisiwe esikhunjeni. Kulapho isayensi yezinto ezibonakalayo ihlangabezana nesiyalo sobukhulu—futhi lapho umuntu enganyathelanga kahle ekwakhiweni kwephethini, ukukhetha ingxubevange, noma izinga lokupholisa kungadla amasonto ekusebenzeni kabusha, hhayi amadola kuphela. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siphonse ngaphezu kuka-12,000 izindlu zamavalvu okucindezelayo namasilinda epompo yepiston kusukela ngo-2018—ngalinye libambe ukubekezelelana okuqinile ngaphansi kuka-0.05 mm kanye nemijikelezo engu-300+ yamabha esindayo. Lokho okuhlangenwe nakho kwasifundisa okuthile okubalulekile: ukunemba kwe-Foundry casting kuqala kudala ngaphambi kokuba isithando somlilo sikhanyise.
Idizayini Yokudlala—Hhayi Eyomsebenzi Kuphela
Onjiniyela bavame ukuthuthukisa izingxenye zokuhlanganisa noma ukusabalaliswa kokucindezeleka—bese bekhipha imidwebo elindele ukuthi abakhangisi “bayenze isebenze.” Kodwa ukukhishwa kwesihlabathi nokutshala izimali kunemikhawulo eqinile ngokomzimba. Sake sathola ifayela le-CAD lendlu yephampu ye-cobalt-alloy enezingxenye zodonga ezingu-2.3-mm nezimbambo zangaphakathi ezihlukaniswe ngo-4.7 mm. Ingxenye yaqhekeka phakathi nokunyakaziswa—hhayi ngenxa yokuthela kabi, kodwa ngenxa yokuthi ama-gradient ashisayo ayedlula iwindi lokuqina le-AMS 5387. Saklama kabusha ijiyomethri yezimbambo, sengeza izindawo ezibandayo zendawo, futhi sasusa umugqa wokuhlukanisa ngamadigri angu-8. Isivuno seqe kusuka ku-62% kuya ku-98%.
Ukuhlola okubalulekile esikwenzayo ngaphambi kokucaphuna:
- Ubuncane besigaba ukujiya: ≥4.5 mm ngokusakazwa kwensimbi, ≥3.2 mm kuma-alloys e-cobalt-nickel njenge-T800
- Isilinganiso se-radius-to-wall: Amakhona angaphakathi kufanele abe ≥0.6× ukujiya kodonga oluncikene ukuze kugwenywe izinyembezi ezishisayo
- Ukubekezelelana kwe-Undercut: Isikhunta sesihlabathi sibekezelela ≤15 ° okusalungiswa; amaphethini okutshalwa kwezimali adinga u-≥0.5° ohlangothini ngalunye—noma ama-cores omshini we-CNC
- Ukuhlukaniswa kwesici: Gwema abaphathi abancane, abangabodwa noma ama-flanges—aphole ngokushesha, asuse izinto eziningi, futhi avule izindlela zokushwabana okuncane
Uma i-GD&T yakho idinga isikhundla sangempela esicini esisakazwa ngokuqondile esikhunjeni, qinisekisa ukuthi leyo ndawo izokwenziwa ngomshini ngemva kokusakaza. Sishicilela u-87% wensimbi yethu nensimbi ekucacisweni kokugcina—ngoba izindawo ezisakazwayo azivamile ukubamba ±0.1 mm ukunemba kokuma phakathi kuka-300 mm.
Ukukhetha Kwengxubevange Kushintsha Yonke Into-Ikakhulukazi Uma Ungeke Uyifake Kamuva
Ama-alloys e-cobalt-nickel afana ne-AMS 5387 noma i-T800 awakhethelwa ubuhle. Acaciswa lapho ukumelana nokuguguleka, amandla okunyakaza angaphezu kuka-650°C, noma kuthinta ukusebenza okungewona uzibuthe—njengakumabhobho akhipha uwoyela negesi noma amarola we-winch center anesivinini esikhulu. Kepha lezo zakhiwo ezifanayo zibenza kube nzima ukwenza umshini ngemuva kokusakazwa. Ipulaki eyodwa ye-T800 ithatha amahora angu-11.2 wokugaya i-multi-axis kusetshenziswa amathuluzi e-PCD nesipholile se-cryogenic. Ngakho-ke uma ingxenye yejiyomethri ivuma, sihlanganisa umshini enqubweni yokusakaza ngokwayo—sengeza izimbobo zedowel zasendaweni, amaphedi edatha engaphezulu, noma ama-preforms we-bore ayingxenye ngqo kuphethini yokutshala imali.
Sithola wonke ama-ingots we-superalloy ngemibiko egcwele yokuhlolwa kokugaya (ama-MTR) alandeleka enombolweni yokushisa nokuhlaziywa kwamakhemikhali. Alikho iqoqo elingena esithandweni ngaphandle kokuqinisekiswa kwe-spectrographic. Kungani? Ngoba ukuchezuka okungu-0.03% kokuqukethwe kwekhabhoni ku-T800 kushintsha ubulukhuni bayo obunjengokuphonswa busuka ku-32 HRC kuye ku-41 HRC—obanele ukuhlakaza ukufakwa kwe-carbide okuphakathi nendawo.
Ikhwalithi Ayihlolwa Ngaphakathi-Yakhelwe Ngaphakathi, Isendlalelo Ngesendlalelo
Iningi labasunguli lihlola ukulingisa ezindaweni ezintathu: impahla engenayo, ubukhulu obumaholoholo ngemva kokunyakaziswa, kanye nokuhlola kokugcina okubonakalayo. Singeza ezinye ezine:
- Ukuskena kobuqotho besikhunta: I-X-ray tomography ku-100% wesikhunta segobolondo le-investimenti ngaphambi kokukhishwa kwe-wax
- Thela ilogi yezinga lokushisa: Idatha yesikhathi sangempela se-thermocouple evunyelaniswe enombolweni ngayinye yokushisa
- Imephu yobulukhuni besigaba: Ukufundwa kwe-Rockwell C enamaphuzu angu-12 kuzo zonke izingxenye eziphambanayo zayo yonke indawo
- I-hydrotest esebenzayo: Yonke imizimba yamavalvu okucindezela ibamba ingcindezi elinganiselwe engu-1.5× imizuzwana engu-120—ngokuzwela kokutholwa kokuvuza ku-0.003 cc/min
Sigcina ukulandeleka okugcwele—hhayi okokuhlola nje kuphela, kodwa ngenxa yokuthi lapho ikhasimende libika ukukhathala ngamahora okusebenza angu-14,200, singadonsa ilogu yokuqala yokuthela, ijika lokupholisa, kanye nemephu eqinile yangemva kokwelashwa ngaphansi kwamasekhondi angu-90. Leso sivinini sihlukanisa ukulungiswa kwemsuka nokuqagela.
Kungani i-Hybrid Casting + Machining Ishaya Noma Yedwa
Ezinye izitolo ziphatha ukusakaza kanye ne-CNC njengezinyathelo ezilandelanayo. Sibaphatha njengemfundo ehlangene. Izindlu zethu zamasilinda ziqala njengezikhala ze-sand-cast ductile iron-kodwa indawo ebhorekile ayiqedwa ngokuphenduka. Isakazwa ngesabelo sobukhulu obungaphezu kuka-0.8 mm, bese icijwa *ngendlela efanayo* esetshenziselwa ukugaya kokugcina kwe-CNC kobuso obukhuphukayo nemicu yembobo. Lokho kuqeda ukushintsha kwedatha okubangelwa ukulungiswa—futhi kubambe ukugxila phakathi kwe-ID ye-bore ne-flange OD kuye ku-0.015 mm ubude obungu-280 mm.
Lokhu kugeleza komsebenzi okuxubile kusivumela ukuthi silethe izingxenye ezinjengama-roller we-winch shaft yemoto yobunjiniyela anamajenali athela phansi *kanye* namazinyo egiya asakazwa—womabili ahlangabezana nokubekezelelana okujwayelekile kwe-ISO 2768-mK, nokho abelana ngomlando owodwa oshisayo nesakhiwo sokusanhlamvu. Akukho ukwelashwa kwesibili kokushisa. Ayikho ingozi yokuhlanekezela. Ukugeleza kokukhiqiza okukodwa nje, irekhodi elilodwa lekhwalithi, idethi eyodwa yokulethwa.
I-Foundry casting iphumelela lapho i-metallurgy, i-geometry, nenjongo yokukhiqiza iqondana—hhayi uma kuxoxiswana ngayo ngokwehlukana. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., asigcini nje ngokuphonsa insimbi. Sibeka ithemba—ekuzinzeni kohlangothi, ubuqotho besakhiwo, kanye nokusebenza okuphindaphindwayo ngaphansi kwengcindezi. Ukuthi ucacisa isisekelo sepompo yensimbi engagqwali noma ufaneleka i-cobalt alloy nozzle ukuze uthole isevisi eyeqisayo, ilungelo i-Foundry casting umlingani akalindi umdwebo wakho. Basiza ukuyibhala.
