Lapho onjiniyela becacisa ingxenye yamasistimu asebenza ngomfutho omkhulu we-hydraulic noma amaphampu e-oilfield, abadingi insimbi kuphela—bayayidinga. ukubikezelwa kwe-metallurgy, ukuzinza kwe-dimensional okuphindaphindiwe, futhi ukubekezelela i-zero kokungahambisani kwe-microstructural. Ngakho-ke ukutholakala kweqiniso i-investment casting alloy factory akusona isinyathelo sokuthenga—kuyisinqumo sokunciphisa ubungozi.
Kungani "Ingxubevange" Ibaluleke Kakhulu Kunokuba "Ukusakaza" Kuwodwa
Izisekelo eziningi zenza insimbi noma i-carbon steel. Bambalwa abaphatha ama-superalloy e-cobalt-nickel afana ne-AMS 5387 noma izinto ze-T800-grade ngaphandle kokuqhekeka, ukungqubuzana, noma ukuhlukaniswa okusanhlamvu. Sibone amaphuzu amathathu okuhluleka avamile kumaketanga okunikezela emhlabeni wonke: okokuqala, ukwelashwa kokushisa okungahambisani ngemva kokufakwa kwe-investimenti—okuholela ekuhlukeni okungu-12–18% kokuqina kwe-Rockwell C kuwo wonke amaqoqo; okwesibili, ukushiswa kwegobolondo le-ceramic okunganele okubangela ukufakwa kwe-oxide ebusweni ezindaweni ezibucayi zokuvala; okwesithathu, ukusetshenzwa kwe-post-cast okususa ubuqotho bomumo we-net-net inqubo okwakuhloswe ukuyiletha.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., wonke umbhobho wengxubevange ye-cobalt, zonke izindlu zepompo ze-AMS 5387, kanye nepulaki ngayinye esekwe ku-T800 iqala ngokulandeleka kwempahla eluhlaza eqinisekisiwe—hhayi nje izinombolo zenkatho, kodwa imibiko egcwele yokuhlolwa komshini iqinisekiswa ngokumelene ne-ASTM E1476 kanye ne-ISO 90001: A. Akukho okushintshiwe. I-alloy ichaza uphahla lokusebenza; inqubo yokulingisa kufanele iwugcine.
Ukuhlanganiswa Okuqondile Akuyona I-Buzzword—Iphuzu Lokulawula
Awukwazi ukuqinisekisa ukuzungeza okungu-±0.015 mm kusilinda sephampu ye-piston uma ukusakaza, ukwelashwa kokushisa, nokuqedwa kwe-CNC ye-5-eksisi kwenzeka ezindaweni ezihlukene. Umlando oshisayo uyalahleka. Ukushintsha kwezithenjwa ze-Datum. Imininingwane yokuqedwa kobuso iyakhukhuleka.
Kungakho indawo yethu ye-Qingdao isebenza njengokugeleza komsebenzi okukodwa okuqhubekayo: ukutshala imali → ukukhishwa komoya okulawulwayo → ukukhulula ingcindezi → ukujika okunembayo nokugaya → ukuhlola okungabhubhi (UT + ukungena kukadayi) → ukuqinisekiswa kokugcina kwe-CMM ngokumelene nama-callout we-GD&T. Isibonelo, amarola we-winch yesikhungo semoto yobunjiniyela ahlolwa ngokugcwele ibhalansi ejikelezayo *ngemuva* kokugaya okokugcina—hhayi ngaphambili. Ngoba ukungalingani akuphathelene nenqwaba yodwa; kumayelana nendlela ukucindezeleka okuyinsalela okuhlangana ngayo nomthwalo we-centrifugal ku-3,200 RPM.
Lokhu akulona ithiyori. I-OEM yaseNyakatho Melika yehlise ukwehluleka kwenkambu ngo-67% ngemva kokusuka kuchungechunge lwabahlinzeki bezigaba eziningi ukuya kusixazululo sethu somthombo owodwa wemizimba yamavalvu okucindezela—ikakhulukazi ngenxa yokuthi silawula yonke indlela yomshini oshisayo ukusuka kuphethini ye-wax ukuya ekuhlolweni kokusebenza.
Ukunemba Komhlaba Wangempela Kudinga Ukuqinisekiswa Komhlaba Wangempela
“Ukunemba okuphezulu” kusho izinto ezihlukene kubasebenzisi abahlukene. Kumklami wephampu, ukugxila kwayo phakathi kobuso be-bore kanye ne-flange ngaphansi kuka-0.02 mm TIR. Kunjiniyela wokugqwala, ubulukhuni bayo obuphezulu Ra ≤ 0.8 µm *emva* kokudlula*—akukho ukusebenza kabusha okuvunyelwe. Eqenjini labalungisayo, ukushintshashintsha phakathi neminyaka emihlanu yokukhiqiza ngaphandle kokulinganisa kabusha amathuluzi.
Siqinisekisa zontathu-njalo. Amabhilidi angenayo e-cobalt alloy athola ukuhlaziywa kwe-spectrographic. Ubukhulu obungaphakathi kwenqubo buqinisekiswa kusetshenziswa ama-Zeiss CONTURA G2 CMM alinganiswa nsuku zonke. Izingxenye zokugcina zihlolwa ingcindezi yokusebenza ku-1.5 × ingcindezi yokusebenza elinganiselwe, ngokuqapha kwesilinganiso sokuvuza kwesikhathi sangempela sehle siye ku-10.−6 mbar·L/s. Futhi yebo—sigcina ukulandeleka okugcwele kwedijithali: iyiphi inqwaba yesithando somlilo, iyiphi i-opharetha, iyiphi inguqulo yohlelo lwe-CMM, iyiphi inombolo yenkatho epholile. Uma okuthile kwehluleka enkonzweni, siyazi kahle ukuthi sibheke kuphi.
Amakhasimende avame ukubuza: “Ingabe ungakwazi ukubamba isikhundla sangempela phakathi kuka-0.025 mm kububanzi obungu-320 mm beflange enezimbobo zamabhawodi angu-12?” Yebo—uma umdwebo uhlanganisa okuhlosiwe kwedatha, ukucaciswa kwezinto ezibonakalayo, kanye nenjongo yokusebenza. Kodwa sizophinde sikutshele kusenesikhathi uma ngabe i-GD&T icaciswe ngokwedlulele kuhlelo lokusebenza, noma uma enye i-sand-cast ingahlangabezana nokusebenza ngezindleko eziphansi ezingama-40%. Ukubonisa ngale akuyona inqubomgomo. Kuyisiyalo sobunjiniyela.
Lapho Ukunemba Kuhlangana Khona Ubambiswano
An i-investment casting alloy factory kufanele yenze okungaphezu kokuletha izingxenye. Kufanele ikusize ugweme imijikelezo yokuklama kabusha, ukugijima okulahliwe, nokubambezeleka kokufaneleka kwesigaba sekwephuzile. Kungakho usekelo lwethu lwephrojekthi luqala ngaphambi kwe-PO: isibuyekezo sokudweba ngempendulo yokwenziwa, izinketho zokushintsha izinto ezibonakalayo ezisekelwa idatha eqinile/ye-creep, kanye nezikhathi zokuhola ze-prototype ngaphansi kwezinsuku ezingu-21 zama-alloys afanelekayo.
Sinikeza izihlanganisi zesistimu ye-hydraulic e-Germany, abakhi bemishini engaphansi kolwandle e-Norway, kanye nabakhiqizi bephampu abasebenza kanzima kuyo yonke i-Southeast Asia—hhayi ngabasabalalisi, kodwa ngokubandakanyeka okuqondile kobuchwepheshe. Ngoba uma ukucaciswa kwakho kubiza i-AMS 5387 ene-HRC 42–46 kanye nokumelana nokugqwala kwe-intergranular ngayinye ye-ASTM A262 Practice E, izitatimende zamandla ajwayelekile ngeke ziwunqamule. Udinga ulwazi olufakazelwe ngalelo banga elinembile, ngaphansi kwalezo zimo ngqo.
Uma sibheka phambili, sinweba i-R&D yethu ye-hybrid casting-machining—ikakhulukazi ezicini ezinezindonga ezincane, ezinesilinganiso esiphezulu lapho ukutshala imali okuvamile kufinyelela imikhawulo. Kodwa ukugxila kwethu okuyinhloko kuhlala kungashintshile: ukuletha izingxenye zensimbi eziyinkimbinkimbi, ezibalulekile lapho ukunemba kobukhulu, ubuqotho be-microstructural, nokuthembeka kokusebenza kungekona ukuhwebelana. Abanakuxoxisana.
