Lapho onjiniyela bayacacisa i-alloy investment casting factory izinsiza zamavalvu odonsa amanzi abalulekile kumishini noma izindlu zephampu ezinomfutho ophezulu, azithengi izingxenye nje kuphela—zivikela ukuqina kobukhulu ngaphansi kwemithwalo engu-300 MPa, ukungaguquguquki kwe-microstructural kuwo wonke amayunithi angamayunithi angu-500, kanye nokungabekezeleli nhlobo ukuqina kwe-cobalt-nickel interfaces. Lokho kuyiqiniso lokusebenza-hhayi ulimi lokumaketha.
Kungani i-AMS 5387 kanye ne-T800 Idinga Imboni Ekhethekile Yokutshala Imali Yengxubevange
Senze izingxenye zephampu ye-cobalt alloy engaphezu kuka-12,000 AMS 5387 kusukela ngo-2021. Esikufundile kusenesikhathi: abasunguli abajwayelekile bayehluleka lapha—hhayi ephepheni, kodwa ngokusebenza. Ama-superalloys asekelwe ku-cobalt ancipha ngokungalindelekile ngesikhathi sokuqina. I-conductivity yabo eshisayo iyingxenye yensimbi engagqwali. Futhi ukuqina kwabo buyakhuphuka ngemva kokwelashwa kokushisa, okwenza imishini yangemuva kokusakaza ibe ukugembula ngaphandle kwamandla ahlanganisiwe e-CNC.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siphatha ukufakwa kwe-alloy investment cast njengenqubo evalekile—hhayi i-handoff. Isitifiketi se-Raw material siqala ngemibiko yokuhlolwa kwesigayo ehambisana ne-ASTM A992 ne-AMS 5718 specs. Amathuluzi ethu ephethini ye-wax kusebenzisa isikhunta se-SLA esingu-5-μm ukuze sibambe ±0.05 mm ukubekezelelana komugqa ngaphambi kokwakhiwa kwamagobolondo. Bese kuba nesinyathelo esibucayi esinganakwa kakhulu: ukukhishwa kwe-waxing okulawulwayo ku-120°C amahora angu-4, hhayi ku-180°C imizuzu engu-30. Yisheshise, futhi uthola imifantu emincane egobolondweni le-ceramic. Sibone amaklayenti amathathu aseNyakatho Melika enqaba inkatho yonke ngenxa yalokhu kuchezuka okukodwa.
Lokhu akulona ithiyori. Yingakho imibhobho yethu ye-cobalt alloy iphila izinyanga ezingu-18 endaweni yegesi emuncu lapho izingxenye zabancintisana nazo zehlulekile ngenyanga yesi-7. Umehluko? Isakhiwo sokusanhlamvu esingaguquki sisuka ekulawuleni izinga lokushisa elinembile (1,480°C ±5°C) kanye nokuqina okuqondisayo ezithandweni ezisizwa ngevacuum.
Ukuhlanganiswa Okuqondile Akuyona I-Buzzword-Kungumshuwalense Wakho We-Dimensional
Amanye amafemu enza. Eminye imishini. Bambalwa abenza kokubili—futhi bambalwa abasazivumelanisa. Nakhu okwenzekayo uma bengenzi: isilinda sendlu esakhiwe ku-±0.3 mm sibekezelelana sifika kuseli ye-CNC. Imishini isusa izinto ezingu-2.5 mm. Ingcindezi eyinsalela isabalaliswa kabusha. Final bore roundness drifts ukudlula i-GD&T callout Ø0.02 mm. Izinga le-Scrap likhuphuka lisuka ku-1.2% liye ku-8.7%.
Indawo yethu ethobela i-ISO iqeda leyo ngozi. Yonke insimbi noma insimbi engagqwali igeleza iqonde ngqo esikhungweni sethu semishini se-5-axis—akukho ukuphatha kwangaphandle, akukho mabhayisikili ashisayo phakathi kwezitolo. Sisebenzisa ukuqinisekiswa kwe-CMM okusekucubunguleni ngemva kokugoqa, ukuqeda kancane, kanye nokudlula kokugcina. Ngezindlu zephampu ye-piston, lokho kusho ukulinganisa ijometri ye-spline yangaphakathi *ngaphambi* kokuqina, bese uhlola kabusha ngemva kokushisa ukuze uqinisekise ukuthi ukuhlanekezela kuhlala ngaphakathi kuka-0.015 mm.
Amakhasimende ayabuza: “Ingabe ungabamba isikhundla sangempela sezintambo ezingu-6× M12 ngokuhlobene nendiza yedatha?” Yebo—kodwa kuphela ngenxa yokuthi ilebhu yethu ye-metrology iqinisekisa yonke into ngokuqhathaniswa nezindinganiso ezilandelekayo ze-NIST masonto onke. Hhayi njalo ngekota. Hhayi “njengoba kudingeka.” Maviki onke.
Ukuqinisekiswa Komhlaba Wangempela Kwedlula Izitifiketi Zephepha
Izitifiketi zibalulekile—kodwa kuphela uma zisekelwa isenzo. Sigcina ukulandeleka okugcwele: izinombolo eziningi eziqoshwe kuwo wonke amapulaki e-cobalt, amalogi omjikelezo wokuphatha ukushisa ahlanganiswe neqoqo ngalinye le-AMS 5387, kanye nemibiko yesiqhathanisi esibonakalayo efakwe kungobo yomlando iminyaka engu-10. Lapho i-OEM yaseYurophu ifuna ubufakazi bamazinga okufakwa okungeyona eyensimbi kuma-T800 alloy shafts, sadonsa idatha yoqobo ye-spectrograph—hhayi ishidi lesifinyezo.
Siphinde sixazulule izinkinga abanye abazigwemayo. Iklayenti elilodwa laseNingizimu-mpumalanga ye-Asia lalidinga i-winch center shaft engajwayelekile ene-asymmetric cooling fins kanye nama-splines aphazamisekile. Ukusakaza okujwayelekile akukwazanga ukugcwalisa izingxenye ezincane. Sidizayine kabusha isistimu yokufaka isango, sengeza okokufaka okupholile kwendawo, futhi sasebenzisa ukulingisa okushisayo ngaphambi kokuthela kokuqala. Umphumela: ukugunyazwa kwesihloko sokuqala ngosuku lwe-14—hhayi izinsuku ezingama-45 ezicashunwe kwenye indawo.
Akuyona inhlanhla leyo. Inama-metallurgists asebenze ama-pump ama-rigs *kanye* nabahleli bohlelo be-CNC abenze izinhlobo ezihlukahlukene ze-cobalt ezingu-30+. Bahlala ndawonye ngesikhathi sokubuyekezwa konjiniyela—hhayi kuma-silo.
Lokho Okutholayo Empeleni Kule Factory Investment Casting Alloy
Uthola izingxenye ezisebenzayo-hhayi nje ezilingana. Amavalvu okucindezela avala kubha engu-415 ngaphandle kokukhasa. Izisekelo zephampu ezidambisa ukudlidliza ku-3,200 RPM ngaphandle kokuzwakala. Amapulaki e-cobalt alloy amelana nokugwaza kumaphampu ancibilikayo anodaka lapho u-316 ehluleka khona ezinsukwini ezingu-90.
Uthola ukubikezela kokulethwa: isikhathi sokuhola se-prototype sezinsuku zebhizinisi ezingu-22, ama-oda evolumu emaphakathi athunyelwa phakathi namaviki angu-6—aqinisekiswe ngokubhaliwe. Azikho izigatshana "kuncike ekutholakaleni kwezinto ezibonakalayo". Sine-AMS 5387, T800, ne-ASTM A48 Class 35 yensimbi empunga esizeni.
Uthola ubambiswano lobunjiniyela—hhayi ukuthatha ama-oda. Sihlaba umkhosi izingxabano ze-GD&T *ngaphambi kokuba* kuqale ukusebenza kwamathuluzi. Siphakamisa ukulungiswa kwerediyasi okwehlisa izindleko zokuphonsa ngo-18% ngaphandle kokufaka engozini impilo yokukhathala. Sabelana ngezitifiketi zezinto ezingavuthiwe, amashadi okuphatha ukushisa, nemibiko ye-CMM—hhayi nje isitembu “sokudlula/sokwehluleka”.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza empambanweni yokuqondisa kwe-metallurgical kanye nokunemba komshini. Uma uhlelo lwakho lokusebenza ludinga ukuphindaphinda ezinhlelweni ze-cobalt-nickel, ubuqotho besakhiwo ezindaweni ezigqoke kakhulu, noma ukusebenza okusebenzayo—hhayi nje ukuthobela imithetho—khona-ke lokhu i-alloy investment casting factory iletha ukuthi yiziphi izithembiso zamaphepha, nokuthi yiziphi izimo zenkambu ezidinga.
