Lapho onjiniyela bayacacisa Ingxubevange 6 izingxenye, abagcini nje ngokukhetha ukwaziswa—bazibophezela ekuzinzeni kobukhulu ngaphansi kuka-1,200°F, ukumelana ne-sulfid endaweni yegesi emuncu, nokungabekezeleli nhlobo ukungahambisani kwesakhiwo esincane. Ngakho-ke ukutholakala kweqiniso Ingxubevange 6 izingxenye ifektri ayimayelana nentengo noma isikhathi sokuhola uwedwa. Kumayelana nokuthi indlu yakho yephampu izosinda yini emijikelezweni engu-25,000 ku-8,000 psi-noma ukuthi umlomo wakho we-cobalt alloy uyaguguleka ngaphambi kokusebenza.
Kungani i-AMS 5387 Ingeyona Nje Enye Inombolo Yeshidi Elicacisiwe
Sibone ukwehluleka okuthathu okuvamile ezingxenyeni ze-Alloy 6: ukuqhekeka komngcele wokusanhlamvu ngemva kokwelashwa kokushisa, ukunwetshwa okushisayo okungafani phakathi kwezindawo ezisakazwayo nezinomshini, kanye nokuwohloka kokuqedwa kwendawo ngesikhathi sokugaya amaphasi okugcina. Zonke zibuyela emuva kumsuka owodwa—ukulawula inqubo ehlukene. I-AMS 5387 idinga ukuhlangana okuqinile phakathi kwezinga lokuqinisa lokusakaza, isikhathi sokucwilisa isixazululo, kanye nesu lendlela yamathuluzi ehlanganisa ama-eksisi amaningi. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., siqhuba lonke uchungechunge lwangaphakathi: ukufakwa kwe-investimenti yezinhlamvu ze-cobalt-nickel ze-T800-grade, i-CNC yokwenza izigayo ezivundlile eziyi-5-axis ezinesinxephezelo esishisayo sesikhathi sangempela, kanye ne-HIP yangemuva komshini (lapho kudingeka khona ukucindezela kwe-isostatic). Awekho ama-handoffs. Akukho ukuqagela kweqoqo-kuya-inqwaba. Siqinisekisa yonke inkatho ngokumelene nosayizi wokusanhlamvu we-ASTM E112, i-ASTM E384 microhardness, kanye namaphrothokholi okuhlola ingcindezi ye-ASME B16.34—hhayi nje ekuhlolweni kokugcina, kodwa ngemva kokuphasa kanzima, ukuqeda kancane, nokuqeda.
Lapho “Ngokwezifiso” Kusho Ubunjiniyela, Hhayi nje Ijometri
Abanye abahlinzeki baphatha izingxenye ze-Alloy 6 zangokwezifiso njengamafayela e-CAD anokubekezelelana. Siwaphatha njengamasistimu asebenzayo. Izindlu zesilinda sephampu ye-piston ayichazwa nge-ID/OD yayo—ichazwa ngokuthi iziteshi zayo zokupholisa zangaphakathi zisebenzisana kanjani nezinkambu zengcindezi zasendaweni ngesikhathi sokukhuphuka komthwalo wesikhashana. Kungakho inqubo yethu yokucaphuna iqala ngokubuyekezwa kwe-GD&T—hhayi ukwamukela ukwamukelwa. Simaka izinkinga ezingaba khona ezifana nalezi: izindonga ezincane ezingasekelwe eduze nezindawo zokungena zoketshezi lwesivinini esiphezulu, ukuphazamiseka phakathi kokuhlanekezelwa kokuphathwa kokushisa kanye nokuphuma kwesihlalo esinezihlalo, noma ukufinyelela kwethuluzi elingelona elilungile lokugaywa kwekhonta yangaphakathi. Ngonyaka odlule, saklama kabusha i-winch center shaft roller yemoto yobunjiniyela esekelwe e-EU—hhayi ukuze kwehlise izindleko, kodwa ukuze kuqedwe i-0.0015″ ye-radial runout drift ebonwe ngemva kwamahora angu-400 okusetshenziswa kwenkundla. Ukulungisa? Ukuhambisa uhlaka lwereferensi yedatha nokushintsha kusukela ekulingiseni kwesihlabathi kuya kokusasiswa ngaphambili kwe-investimenti ngokulawula okuqinile kodonga olunjengokusakazwa. Umphumela: Ukwehliswa kwama-92% ekubuyiselweni kwenkambu.
Ukuhlanganiswa Okumile Ongakukala—Hhayi Ukumane Ufake Isimangalo
“Kuhlanganiswe ngokuqondile” akusho lutho ngaphandle uma ungakwazi ukuyilandelela. Nakhu ukuthi kubukeka kanjani phansi esitolo:
- Ukulandeleka kokubalulekile: Yonke i-billet ye-AMS 5387 iphethe imibiko yokuhlola egcwele yokugaya—okuhlanganisa i-Co, Cr, Ni, Mo, Fe, C, Si, Mn, W, ne-N yokuqukethwe—kanye nezixhumanisi ezinombolweni yokushisa yoqobo evela kubahlinzeki abagunyaziwe
- Inqubo yokukhiya: Izibunjwa zokubunjwa kwesihlabathi zenziwe nge-CNC kusuka kumaphethini e-aluminium; amaphethini we-wax ophonsa utshalomali aphrintwe nge-3D kusukela kuma-STL aqinisekisiwe anobungane obungu-±0.02 mm; zonke izinhlelo ze-CNC zenziwa ukulingisa okomile nokuhlolwa kwesihloko sokuqala ngaphambi kokusikeka kwensimbi
- Ukuqina kokuhlola: Izilinganiso ze-CMM zihlanganisa ukuhlola okunxeshezelwe kwezinga lokushisa ku-20°C ±1°C; i-optical profilometry ihlola i-Ra ≤0.4 μm ezindaweni zokuvala; ukuhlolwa kokuvuza kwe-helium kuqinisekisa ubuqotho ku-1×10⁻⁹ mbar·L/s kuma-assemblies abucayi
Lokhu akubona ubunjiniyela obudlulele. Kuyindlela esibamba ngayo ukubekezelela indawo okungu-±0.005 mm kumaphethini we-flange enezimbobo ezingu-12 kumadayamitha angu-320 mm—futhi siletha imiphumela ephindaphindwayo kuwo wonke amayunithi okukhiqiza angu-150.
Ukulethwa Kwangempela Komhlaba—Ngaphandle Kokuyekethisa
Yebo, izingxenye ze-Alloy 6 zithatha isikhathi eside ukwenziwa. Kodwa “isikhathi eside” akumele sisho “okungabikezelwa.” Ukuhamba kwethu okuthambile kuhlanganisa ukuhlela okungenabhafa kokusebenza kwezindlela ezibalulekile, izivumelwano zezinto ezingavuthiwe zemithombo emibili ukuze kugwenywe ukubambezeleka kochungechunge lokunikezela, namaseli esibonelo azinikele angaqhudelani namandla okukhiqiza. Kuma-OEM asebenza ngohydraulic aseNyakatho Melika, isikhathi sokuhola esimaphakathi sezindlu zamaphampu ze-AMS 5387 singamaviki angu-14—kusuka e-PO kuya edokini—kungakhathaleki ukuthi usayizi we-oda lingakanani. Kumakhasimende aseNingizimu-mpumalanga ye-Asia adinga i-T800 alloy plugs enezindawo ezine-nitrided, amasonto ayi-10, nemibhalo egcwele ithunyelwa ngedijithali ngaphambi kokulethwa ngokomzimba. Asithembisi “okushesha kakhulu.” Siyathembisa *ngokuqinisekile*. Ngoba lapho isikhathi sokusebenza sekhasimende lakho sincike esihlalweni sevalvu ye-cobalt alloy, isiqiniseko akuhle ukuba sibe nakho — ukuphela kokucaciswa okubalulekile.
Uma iphrojekthi yakho elandelayo ibandakanya Ingxubevange 6 izingxenye ifektri ukusebenzisana—kungakhathaliseki ukuthi okwezingxenye zephampu ye-AMS 5387, imibhobho ye-cobalt alloy, noma imihlangano engajwayelekile ye-T800 eyenziwe ngomshini—kuqala ngokuqondanisa kobunjiniyela, hhayi ukuhanjiswa kwe-RFQ. Uzakwethu olungile akahlangani nje nemininingwane. Balindele izindlela zokuhluleka ngaphambi kokuthi kundiza i-chip yokuqala.
