Lapho onjiniyela becacisa a i-wax metal casting factory elahlekile kumavalvu e-hydraulic abalulekile emishini noma izindlu zepompo ezinomfutho ophezulu, azithengi nje izingxenye-zikhipha ukuzethemba kwe-metallurgical. Sibone amaphrojekthi amaningi kakhulu esima esigabeni sesibonelo ngoba i-Foundry ayikwazanga ukubamba ±0.02 mm ku-AMS 5387 cobalt alloy nozzle bore—noma okubi nakakhulu, ilethwe isakhiwo sokusanhlamvu esingahambelani kuwo wonke amaqoqo. Yingakho ukunemba kungesona isimangalo sokumaketha lapha. Yisisekelo.
Kungani ukulahlwa kwe-wax okulahlekile kusaphumelela ezintweni eziyinkimbinkimbi, ezinengxubevange ephezulu
Ukukhishwa kwensimbi ye-wax elahlekile—okubizwa nangokuthi i-investment casting—kusala kungenakuqhathaniswa nobunkimbinkimbi bomumo wenetha kuma-superalloy. Ukulingisa isihlabathi akukwazi ukuphinda ubuqotho bodonga oluncane lwezindlu zesilinda sephampu ye-cobalt esekelwe ku-T800. I-die casting ihluleka ngephuzu lokuncibilika eliphezulu le-cobalt-nickel kanye nemvelo ehubhukayo. I-Centrifugal Casting ayinakho ukulawula kwe-GD&T okudingekayo kuma-valve embobo yokucindezela. Ekusetshenzisweni komhlaba wangempela, sivamise ukubona ukukhukhuleka kwe-dimensional ngaphezu kuka-±0.15 mm okulingana nesihlabathi—okwanele ukuqalisa ukuvuza kwe-seal ku-3,000 psi. Ukukhishwa kwe-investimenti kuyakulungisa lokho. Inqubo yegobolondo layo le-ceramic iletha ubuso buqeda phansi ku-Ra 1.6 μm nokubekezelela kuqine njengo-±0.05 mm kumadayamitha abalulekile—ngaphandle komshini wesibili ku-60% wezingxenye zethu zephampu ye-cobalt alloy.
Amakhono amane angaxoxiswana imboni yakho yokukhipha insimbi elahlekile kufanele ifakazele
Umlingani othembekile akagcini nje ngokugijima amaphethini we-wax futhi athulule insimbi. Bangabanikazi be-physics ngemuva kwayo. Nakhu esikuqinisekisayo ngaphambi kokugunyaza noma yimuphi umsebenzi omusha wokulingisa:
- Ukulandeleka kokubalulekile kwehle kunombolo yokushisa—hhayi nje “i-AMS 5387 ehambisanayo.” Yonke ipulaki ye-cobalt alloy esiyiphonsayo inemibiko yokuhlola egcwele yokugaya, ukuqinisekiswa kwe-spectrographic, kanye namalogi omlando oshisayo
- Ukuqinisekiswa kwe-CMM okungaphakathi kwenqubo ngezigaba ezintathu: ukuhlanganiswa kwe-wax (ngaphambi kokukhishwa kwewax), ubuqotho begobolondo (ngemuva kokudubula), kanye nejiyomethri yokwelapha ngemva kokushisa (ngaphambi kokuqeda)
- Ukulawulwa kwe-Microstructure ngemephu yesithando somlilo: azikho izindawo ezishisayo, azikho izindawo ezibandayo. I-vacuum yethu yokungeniswa ifaka ama-gradients okushisa elogi njalo ngemizuzwana eyi-12 ngesikhathi sokuthela—okubalulekile ukugwema isigaba se-sigma kuma-cobalt-nickel alloys
- Ukuhlola okusebenzayo kubhakwe ekukhululweni: yonke i-valve ye-pressure cast ithola ukuhlolwa kokuvuza kwe-helium ku-1.5 × ingcindezi yokusebenza ngaphambi kokuthunyelwa
Abanye bangase baphikise ngokuthi ukucutshungulwa kwe-CNC kukodwa kwanele izingxenye ezinemba okuphezulu. Kodwa-ke, ukwenza i-AMS 5387 kusuka kubha eqinile kumosha u-78% wezinto ezibonakalayo—futhi kwethula ingcindezi eyinsalela ebeka engcupheni impilo yokukhathala kumarola we-winch center shaft. Ukusakazwa kokutshalwa kwezimali kuqala ukuma eduze nenetha. Khona-ke sisebenza ngomshini kuphela okubalulekile: izindawo zokuvala, amajenali, kanye namafomu entambo. Umphumela? U-42% wesikhathi esiphansi somjikelezo kanye nempilo yesevisi ende engu-3× ezivivinyweni zasensimini.
Lapho inhloso yokuklama ihlangabezana neqiniso eliyisisekelo
Sithola lo mbuzo masonto onke: "Ungakwazi ukwenza le geometry?" Impendulo incike kancane kumafayela e-CAD nokuningi kokuthi ingxenye iziphatha kanjani ngaphansi kokucindezeleka okushisayo. Izimbambo ezizacile ezingaphansi kuka-4 mm ziyagoqeka egobolondweni. Amakhona angaphakathi abukhali abamba izinsalela zobumba. Ama-engeli asalungiswa angaphansi kuka-0.5° abangela ukuhluleka kokukhipha i-wax. Yingakho isibuyekezo sethu sobunjiniyela singayeki kwa-GD&T. Silingisa ukushwabana kwe-wax, ukunwetshwa kwegobolondo, kanye nokuqina kwensimbi sisebenzisa i-MAGMASOFT®—futhi sibuyisela imidwebo echazwe ngamanothi okwenziwa phakathi kwamahora angu-48. Isibonelo, sisanda kuklama kabusha isisekelo sephampu esingajwayelekile ngokwengeza izikhuphukeli ezimbili zokungena zamasu. Lokho kwaqeda i-microporosity ku-flange ethwala umthwalo-futhi kwadlula ukuhlolwa kwe-ASTM E192 ultrasonic ekuthululeni kokuqala.
Ukukhetha imboni yakho yokukhipha insimbi ye-wax elahlekile kusho ukukhetha iphrofayela yakho engcuphe ye-supply chain
Abathengi bomhlaba wonke bakhetha i-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. hhayi ngezindleko eziphansi kakhulu—kodwa ngezindleko eziphansi *zizonke zobunikazi*. Indawo yabo ethobela i-ISO ihlanganisa ukulingisa, ukukhanda kwe-multi-axis, kanye nokudlula endaweni eyodwa elawulwayo. Awekho ama-handoffs. Akukho ukungafani kwenqwaba. Akukho ukuvuselelwa okumangazayo. Lapho i-OEM yaseYurophu idinga amayunithi angu-120 we-cobalt alloy nozzle emugqeni wesikhathi wamaviki angu-10, silethe isivuno sephasi yokuqala engu-100%—enezitifiketi zezinto ezibonakalayo ezigcwele, imibiko ye-CMM, namarekhodi okuhlola avuzayo afakiwe. Leso sikali sokuthembeka: ukuhamba komsebenzi okuthambile kusekela ukulethwa okuzinzile kusuka ku-prototype (ezimbalwa njengezingcezu ezi-5) ngokusebenzisa ukugijima kwevolumu ephakathi (kufika kumayunithi angu-5,000 / ngonyaka).
Uma uhlelo lwakho lokusebenza ludinga ukuzinza kobukhulu ngaphansi kuka-3,000 psi, ukumelana nokugqwala endaweni yegesi emuncu, noma ukumelana namaphampu abrasive slurry—udinga i-wax metal casting factory elahlekile ephatha i-metallurgy njengesayensi, hhayi umsebenzi wezandla. Qala ngokulandeleka kwezinto. Funa in-process metrology. Kudinga ukuqinisekiswa kokusebenza-hhayi nje ukuthobela ubukhulu. Bese ubheka ozakwethu abashumeka lezo zidingo esinyathelweni ngasinye-kusuka kumjovo we-wax kuya ekufakweni kokugcina.
