Lapho onjiniyela bayacacisa intricist investment casting factory Amandla wamavalvu we-hydraulic abalulekile wemishini noma izindlu zephampu ezigqoke kakhulu, abafuni nje isisekelo-bafuna ukuzinza kobukhulu ngaphansi kwengcindezi engu-200 MPa, ukungaguquguquki kwe-microstructure kuwo wonke ama-AMS 5387 cobalt alloy batches, kanye nokungabekezeleli i-porosity ku-T800-based nozzle. Lelo iqiniso lokusebenza esilibona nsuku zonke kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.—umkhiqizi wezingxenye zensimbi ezinembayo lapho ukutshala imali kungeyona inqubo eyodwa phakathi kweziningi. Kuyisisekelo sezingxenye ezihlulekayo kuphela lapho uhlelo lwehluleka.
Kungani Ukutshala Imali Kungenele-Futhi Kuyini
Abahlinzeki abaningi babhala “i-investment casting” kuwebhusayithi yabo. Bambalwa abalawula iketango eligcwele: ubuqotho bephethini ye-wax ku-±0.05 mm, amaphrofayela okudubula amagobolondo e-ceramic alinganiswe ku-±3°C, isikhathi sokuthulula esisizwa ngevacuum phakathi kwamasekhondi angu-0.8 wethagethi, kanye nokwelashwa kokushisa kwangemva kokusakazwa okubanjwe ku-±5°C ekubambeni amahora angu-4. Sibone ama-athikili okuqala amathathu ahlulekayo avela ezimbonini ezinedumela elihle—konke kulandelelwa umswakama wokomisa amagobolondo ongalawuleki. Esikhungweni sethu se-Qingdao, iqoqo ngalinye liqala ngokuqinisekiswa kokuqina kwe-ASTM E1951 okuvumelana namaphethini ayinhloko, kulandelwa ukuskena kwe-X-ray CT kokusatshalaliswa kokuqina kwegobolondo ngaphambi kokukhishwa kwewax. Yileyo ndlela esibamba ngayo ukuguquguquka kodonga ukuya ku-≤±0.3 mm kumasilinda wephampu ye-piston engu-120-mm-diameter—ngisho noma ukuguqulwa kodonga kwehla kuya ku-4.2 mm.
Lapho I-Cobalt Alloys Idinga Okungaphezu Kokumelana Nokushisa
Ama-superalloy e-cobalt-nickel afana ne-AMS 5387 ne-T800 akunzima ukuwenza umshini—kunzima *ukubikezela*. Izinga labo lokuqinisa umsebenzi likhuphuka ngo-300% ngemva kokujula okungu-0.15 mm. Amamodeli empilo amathuluzi ajwayelekile ayawa. Isixazululo sethu? Sakaza ijiyomethri enomumo we-net-net ngemvume yomshini engu-0.8–1.2 mm, bese usebenzisa okufakwayo kwe-CBN okusekelwe phansi okunama-engeli angu-12° amaraki kanye nemiphetho ecijile engu-0.03 mm—okuqinisekiswa nge-SEM kulo lonke ushintsho lwamathuluzi. Kumapulagi e-cobalt alloy asetshenziswa kumaphampu omjovo we-subsea, lokhu kunciphisa isikhathi somjikelezo ngo-41% uma kuqhathaniswa ne-carbide evamile kuyilapho kunwetshwa ukuphila kwamathuluzi kusuka ezingxenyeni ezingu-8 kuye kwezingu-27 unqenqema ngalunye. Ngokudabukisayo, sigcina ukulandeleka okugcwele kwempahla: inkatho ngayinye iphethe imibiko yokuhlolwa komshini, izitifiketi zokuhlaziywa kwe-spectrographic, nokuqinisekiswa kosayizi wokusanhlamvu nge-ASTM E112 ngayinye. Awekho amaqoqo athunyelwa ngaphandle kobufakazi obubhaliwe bokuqukethwe kwesigaba esingu-δ ≤0.5%—okungaxoxiswana ngakho ukumelana nokukhathala ekulayisheni umjikelezo.
Ukuhlanganisa Okuqondile Okuletha Ukuzinza Empeleni
Abanye abakhiqizi bakhipha izinsiza zokuqedela. Abanye bangaphandle kokwelashwa kokushisa. Asenzi lutho ngezingxenye ezibalulekile. Isikhungo sethu esiqinisekisiwe se-ISO 9001 sinezikhungo zokwenza imishini ye-CNC ezine-contour ye-axis engu-5 kanyekanye, izifudumezi ze-vacuum ezinokufana ±2°C emithwalweni engu-1.2 m³, kanye namathangi okupholisa ngogesi alinganiswe ku-Ra ≤0.1 μm ezisekelweni zephampu yensimbi engagqwali. Kungani lokhu kubalulekile? Ngoba ukuhlanekezela okushisayo ngesikhathi sokunciphisa ingcindezi kuba nomthelela ngqo ekubizeni kwe-GD&T emizimbeni yamavalvu okucindezela. Lapho ikhasimende lisithumelela umdwebo ocacisayo ukubekezelela indawo ye-Ø0.05 mm ezimbobeni ezine zobubanzi obungu-10-mm, siye sasebenzisa imodeli eshisayo yesici *ngaphambi* kokusakaza—bese salungisa ukubekwa kwesikhuphukeli kanye namazinga okupholisa ukuze sikhawulele ukucindezelwa kwensalela <120 MPa. I-athikili yokuqala iphumelele ukuhlolwa kwe-CMM kokuthi Ø0.042 mm. Lelo zinga lokulawula liba khona kuphela lapho ukulingisa, ukwenza imishini, nokwelashwa kokushisa kusebenza ngaphansi kwesistimu eyodwa yekhwalithi—ngelebhu eyodwa ye-metrology eyabelwe.
Okudingwa Onjiniyela Bomhlaba Ngempela—Futhi Ukuthole
Ama-OEM aseNyakatho Melika afuna imibhalo ye-PPAP Level 3. Amafemu ase-European hydraulics adinga isitifiketi se-EN 15085-2 semihlangano eshiselwe. Osonkontileka bamandla aseNingizimu-mpumalanga ye-Asia baphikelela ekuhlolweni kwesifutho sikasawoti ku-ISO 9227 (NSS) amahora ayi-1,000. Sihlangana bobathathu—hhayi njengezengezo, kodwa njengezindawo zokuhlola ezakhelwe ngaphakathi. Wonke ama-oda emboni yokutshala imali abandakanya: ukuqinisekiswa kwempahla eluhlaza okungenayo ngokumelene nezitifiketi zomphakeli eziqinisekisiwe; in-process CMM ihlola ku-30%, 60%, kanye no-90% wokukhiqiza; ukuhlolwa kokugcina kokusebenza (isb., 1.5 × ukulinganisa ukucindezela ukubamba imizuzu engu-30 kuwo wonke ama-valve); kanye nokulandeleka okugcwele kwedijithali phansi kunombolo yelotho yesithando somlilo kanye ne-ID yomsebenzisi. Amakhasimende asitshela ukuthi lokhu kuqeda izinsuku ezingu-7–11 zokubuyekezwa konjiniyela emuva naphambili. Umakhi wephampu waseJalimane unqume umugqa wesikhathi wokwethulwa komkhiqizo omusha kusukela emavikini angama-22 kuye kwayi-13 ngemva kokushintshela enqubweni yethu—ngoba ukuqinisekiswa komdwebo, ukutolika kwe-GD&T, kanye nempendulo yokwenziwa kwenzeka ngeseshini eyodwa yemizuzu engu-90, hhayi imicu ye-imeyili eyisithupha.
Uma isicelo sakho sidinga intricist investment casting factory ukunemba—hhayi nje ukusakaza, kodwa kuyabikezelwa, kuyafundeka, ukunemba okuphindaphindwayo—QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iletha lapho ibaluleke kakhulu khona: empilweni yokukhathala kwengxenye, ubuqotho be-seal, nokuzinza kobukhulu besikhathi eside. Asazi izakhi. Senza ukuzethemba ekunyakazeni.
