Lapho onjiniyela bayacacisa imboni yomphakeli we-wax casting elahlekile ezingxenyeni zensimbi ezibaluleke kakhulu kumishini—cabanga ngamavalvu acindezela kakhulu amanzi, ama-cobalt alloy pump nozzles, noma ama-winch center shaft rollers—awathengi nje ingxenye ethile. Babheja ngokungaguquguquki kwe-metallurgical, ukuphindaphindeka kobukhulu, kanye nokungabekezeleli lutho kokukhubazeka kwe-microstructural. Sibone amaphrojekthi amaningi kakhulu emiswa esigabeni se-prototype ngenxa yokuthi i-Foundry ayikwazanga ukubamba ±0.05 mm ku-AMS 5387 cobalt alloy housing—noma okubi nakakhulu, ilethwe izingxenye eziphethwe ukushisa ezine-oxidation yomngcele wokusanhlamvu engabikwanga. Yingakho ukunemba kungesona isimangalo sokumaketha lapha. Yisisekelo.
Kungani “Ifekthri Elahlekile Yokusakaza Nge-Wax” Isho Okungaphezu Kokusakaza Nje Ukutshala imali
Ikhono leqiniso elilahlekile lokuphonsa i-wax lidlulela ngalé kokuthela insimbi encibilikisiwe kumagobolondo e-ceramic. Idinga ukulawula kukho konke okuguquguqukayo: isinxephezelo sokuncipha kwephethini ye-wax, i-kinetics yokomisa igobolondo, amanani erempu yesithando somlilo, amaphrofayili okupholisa, nemijikelezo yokukhulula ukucindezeleka kwangemva kokusakazwa. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siphatha ingxenye ngayinye ye-cobalt-nickel alloy njengomcimbi we-metallurgical—hhayi umsebenzi wokukhiqiza. Isibonelo, imibhobho esekelwe ku-T800 idinga ukucwiliswa kokushisa kwangaphambili ku-1,120°C amahora angu-4 ngaphambi kokusakazwa, okulandelwa ukupholisa komoya okulawulwayo ukuze kugwenywe imvula yesigaba se-sigma. Yeqa leso sinyathelo? Ingxenye idlula ukuhlolwa okubonakalayo kodwa yehluleka ukuhlolwa kokuqhuma kubha engu-320. Sikuqinisekisile lokhu kwangaphakathi, kuzo zonke iziqephu zokukhiqiza eziyi-17 zezindlu zamasilinda ze-AMS 5387 zemihlangano yephampu yasogwini.
Leli zinga lesiyalo senqubo lihlukanisa isitolo sokulingisa ku-a imboni yomphakeli we-wax casting elahlekile yakhelwe ukusebenza okusebenzayo. Isikhungo sethu esithobela i-ISO sihlanganisa ukutshala imali ngomshini we-CNC onama-axis amaningi kanye nokwelashwa kokushisa kwe-vacuum—konke ngaphansi kophahla olulodwa. Awekho ama-handoffs. Akukho ukuhluka kwe-batch-to-batch kusuka kubathengisi bezinkampani zangaphandle. Uma indawo yephampu ye-piston idinga amaphaseji angaphakathi okupholisa afakwe ngomshini abe ngu-±0.03 mm ngemva kokusakaza, sikwenza ekusetheni okuqinisekisiwe kwe-CMM lapho igobolondo lithelwe khona.
Lapho Ama-Generic Foundries Ehluleka-kanye Nozakwethu Abane-Precision Beletha
Abanye abathengi bacabanga ukuthi konke ukukhishwa kwe-cobalt alloy kuyalingana uma behlangabezana nezimpawu zamakhemikhali ze-ASTM F75. Kodwa i-chemistry yodwa ayiqinisekisi ukuziphatha komshini. Ipulaki elakhiwe lisuka ku-T800 lingase libonise u-950 MPa UTS—kodwa ingxube efanayo, esakhiwe ngendlela engafanele yokuqinisa, yehlela ku-710 MPa futhi iqhekeke ngaphansi kokulayisha umjikelezo. Silinganise lo mehluko ngokuphindaphindiwe sisebenzisa amabha aqinile akhishwe kumagobolondo angempela okukhiqiza, hhayi amakhuphoni okuhlola.
Yingakho ukulandelela kwethu okubonakalayo kungewona umsebenzi wamaphepha—kushunyekiwe. Yonke impahla eluhlaza ye-cobalt-nickel ifika nemibiko egcwele yokuhlolwa komshini, ukuhlaziya okubonakalayo, nokuqinisekiswa kosayizi wokusanhlamvu. Sihlola ikhemistri engenayo ngokumelene ne-spectrometer yethu ye-OES ngaphambi kokuncibilika. Uma okuqukethwe kwekhabhoni kukhukhuleka ukudlula u-0.18–0.22%, siyayenqaba inqwaba—ngisho noma umphakeli eqinisekisa ukuthi uyayithobela. Ngoba ezihlalweni zamavalvu okucindezelayo, u-0.03% wekhabhoni oweqile udala amanethiwekhi e-brittle carbide aqala ukuqhekeka kokukhathala ku-12,000 PSI.
- Izingxenye ze-AMS 5387 cobalt alloy zihlolwe ku-35,000 psi hydrostatic pressure—zero leakage
- Ukulingwa kwensimbi engagqwali kugunyazwe ku-ASTM A743 Grade CA15, enamanani omthelela we-Charpy V-notch ≥35 J ku -40°C
- Ukulingwa kwensimbi ene-graphite nodule count eqinisekisiwe nge-ASTM E2396 ngayinye (awekho ama-flakes ohlobo D)
Ukuhlanganiswa Komhlaba Wangempela—Hhayi nje Ukulethwa Kwezingxenye
Umphakeli othumela ngesikhathi kodwa ongakwazi ukutolika ama-callout e-GD&T noma umaka ukujiya kodonga okubangela ukudabuka okushisayo akayixazululi inkinga yakho. Sishumeka isibuyekezo sobunjiniyela esigabeni sokucaphuna—hhayi njengebhokisi likaqhwi, kodwa njengokuhlela ubungozi ngokubambisana. Ngekota edlule, sibambe iphutha le-engeli yokusalungiswa engu-2.3° kumodeli ye-3D yekhasimende yerola ye-winch center shaft. Ukumayinisa bekuzodinga ukuhumusha kwe-axis engu-5 ngokuchezuka kwethuluzi elingu-0.12 mm—okungazinzi ku-8,000 RPM. Esikhundleni salokho, siphakamise i-tweak encane yejometri futhi siphinde siqalise ukulingisa okushisayo. Umphumela: Isikhathi somjikelezo esisheshayo esingu-37%, ukusebenza kabusha okuyiziro.
Asilindi ukuthi ukuthunyelwa kwe-PPAP kuqale ukulawula ikhwalithi. Okubalulekile okungenayo kuyaqinisekiswa. Amaphethini we-wax athola ukuqinisekiswa kwe-optical scan. Amagobolondo ahlolwa i-X-ray porosity ngaphambi kokutubeka. Ama-casting ahlolwa nge-ultrasonic *ngaphambi* komshini—ngoba ukususa u-4 mm wesitoko endaweni engenalutho kufihla kuphela iphutha. Ukuhlola kokugcina kuhlanganisa ukuhlolwa kokusebenza: ama-valve okucindezela ahamba ngamabhayisikili izikhathi ezingu-10,000 ngengcindezi elinganiselwe yokuhlukanisa; izisekelo zephampu zilayishwe ku-torque engu-3x yokusebenza. Wonke umbiko ufakwe isitembu sesikhathi, usayinwe ngu-opharetha, futhi uboshelwe enombolweni yokushisa kanye ne-ID yokusakaza.
Ukukhetha Ifekthri Yakho Elahlekile Yokuphonsa I-wax—Yini Empeleni Ehambisa Inalithi
Uma uhlelo lwakho lokusebenza ludinga imibhobho ye-cobalt alloy, izindlu zamaphiston agqoke kakhulu, noma izinsimbi ezingagqwali ezingajwayelekile, buza imibuzo emithathu ngaphambi kokusayina i-PO:
- Bangakwazi yini ukufakazela ukulawulwa kwe-metallurgical-hhayi nje i-chemistry-kwibanga lakho elithile le-alloy? Cela imibiko yosayizi wokusanhlamvu, imiphumela yokuhlolwa kokugqwala kwe-intergranular, kanye nezithombe ze-SEM eziphukile ezivela ezindaweni zokukhiqiza zakamuva.
- Ingabe basakaza ngomshini endlini-noma bakhipha izilinganiso ezibalulekile? Ukuqedwa kobuso, ingcindezi eyinsalela, nobuqotho be-microstructure kushintsha lapho izingxenye zihamba phakathi kwezindawo. Ukuhlanganiswa okuqondile akulula—kuwumshwalense wobukhulu.
- Kwenzekani uma umdwebo wakho unokungqubuzana kokwenziwa? Uzakwethu weqiniso umaka kusenesikhathi, uphakamisa ezinye izindlela ezisekelwa idatha yokulingisa, futhi wabelane ngokuhlaziywa kwemodi yokwehluleka—hhayi nje ukuthi “sizozama.”
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kuleyo mpambana-mgwaqo yobungcweti be-alloy ejulile, ukulawulwa kwenqubo edidiyelwe, kanye ne-pragmatism yobunjiniyela. Sakha izingxenye ezisindayo—hhayi nje ukuthi ziphumelele ukuhlolwa. Futhi sikwenzela amakhasimende akala impumelelo ngesikhathi, hhayi izinsuku zokuthunyelwa.
