Lapho onjiniyela becacisa izingxenye zamaphampu asebenza ngogesi, amavalvu angasogwini, noma amasistimu ewintshi asindayo, “ukuvala ngokwanele” akuyona inketho. Ukuchezuka okungu-0.02 mm esihlalweni somlomo we-cobalt-alloy kungase kubangele ukuguga ngaphambi kwesikhathi. I-micro-porosity cluster endlini yesilinda esakhiwe ngesihlabathi ingase ibeke engozini ubuqotho bengcindezi kubha engu-350. Kungakho ama-OEMs omhlaba kanye nabahlinzeki be-Tier-1 bengagcini nje ngokucinga i- ukunemba casting umphakeli ifektri - bahlola isiyalo se-metallurgical, ukuphindaphinda kobukhulu, nokuqinisekiswa kokusebenza ngaphansi kwemithwalo yomhlaba wangempela.
Kungani Ubungcweti Bezinto Ezibalulekile Behlula Ikhono Elijwayelekile
Izisekelo eziningi zenza insimbi noma insimbi engagqwali evamile. Bambalwa abahlakaniphile be-AMS 5387 cobalt alloy - into enokunwebeka okushisayo okucishe kungabi ziro, ukumelana okwedlulele negalling, namandla okubamba ngaphezulu kuka-1,300 MPa ngemva kokwelashwa kokushisa. Senze izingxenye zephampu ezisekelwe ku-12,000 ze-T800 kusukela ngo-2021. Kwenye iphrojekthi yendawo kawoyela yaseNyakatho Melika, ipulaki ye-cobalt esincintisana nayo yehlulekile emahoreni okusebenza angu-4,200 ngenxa yokuhlakazeka kwe-carbide okungahambisani. Iqoqo lethu lidlule amahora angu-9,800 - liqinisekiswe i-metallography yokuphela kwekhasimende nobulukhuni bemephu kuwo wonke amayunithi. Umehluko? Ukusebenzisana okuqondile kwezobuchwepheshe nabahlinzeki bempahla yokusetshenziswa abaqinisekisiwe, hhayi nje ukuthenga ama-oda. Konke ukuncibilika kulandeleka enombolweni yokushisa, umbiko we-spectrographic, kanye nesitifiketi sosayizi wokusanhlamvu - akukho okuhlukile.
Ukuhlanganiswa Okuqondile Akuyona I-Buzzword - Isabelomali Sakho Sokubekezelelana
Ukukhishwa kwe-outsourcing, ukwenza imishini, kanye nokulawula izingcezu zokuqeda. I-Dimensional Drift iyanqwabelana: ukushintsha kwesikhunta → i-core offset → iphutha lokulungisa imishini → ukuhlanekezela okushisayo ngesikhathi sokukhululeka kwengcindezi. Esikhungweni sethu se-Qingdao, ithimba lonjiniyela elifanayo lengamele ukutshalwa kwezimali kwendlu yephampu ye-piston, ukugaya ama-contour ama-axis amahlanu emachwebeni ama-valve angaphakathi, kanye nokumbozwa kokugcina kwe-HVOF kwezindawo zokuvala. Sibamba ama-callout e-GD&T aqine kune-ASME Y14.5 Level III: indawo yangempela ±0.015 mm kuzici zedatha ye-Ø8 mm, ukuqeda okuphezulu kuka-Ra ≤0.4 µm ezindaweni zokuvala ashukumisayo. Awekho ama-handoffs. Azikho izikhala zokuhumusha. Ishidi elilodwa nje lenqubo, uhlelo olulodwa lokuhlola, iketango elilodwa lokuziphendulela.
Awudingi "Isevisi Egcwele" - Udinga Ukunemba Lapho Kubalulekile
Abanye abahlinzeki bacindezela amaphothifoliyo abanzi - amagiya, abakaki, izindlu - ukugxila okudiluzayo. Sigxila ezigabeni ezine ezinezinga eliphezulu: izingxenye ezisebenzayo zomshini we-CNC, izingxenye zengxubevange ye-cobalt-nickel, ukulingwa kwensimbi okunembayo, kanye nensimbi yobuqotho obuphezulu/ukubunjwa kwensimbi. Kungani? Ngoba ngayinye idinga ulwazi lwenqubo ehlukile. Ukuphonsa isihlabathi i-winch center shaft roller kudinga amazinga okupholisa alawulwayo ukuze kugwenywe ukuqhekeka kwe-martensitic ezingxenyeni eziwugqinsi. Ukutshala imali ngombhobho we-AMS 5387 kudinga isinxephezelo esinembile sokuncipha kwephethini ye-wax kanye namaphrofayela okudubula amagobolondo e-ceramic avimbela ukugcotshwa kwendawo. Asiqeqeshi opharetha phakathi kwalezi zizinda. Sinikeza ochwepheshe - ochwepheshe bensimbi abaqinisekise imijikelezo yokuphatha ukushisa kwe-cobalt engu-17, ochwepheshe bemishini abagunyazwe ku-Hurco VMX60Si ngama-superalloy aqinile, ochwepheshe be-CMM balinganiswa ku-ISO 10360-2 nsuku zonke.
Ukuthembeka Kokulethwa Kuqala Ngaphambi Kokuthela Kokuqala
“Ukulethwa ngesikhathi” akusho lutho uma amayunithi okuqala ayi-10 edinga ukusetshenzwa kabusha. Ukugeleza kwethu kokusebenza okuncane kuqala ekudwebeni ukubuyekezwa - hhayi ukuhlela ukukhiqiza. Sihlaba umkhosi izingxabano ze-GD&T ngaphambi kokuthi kuqale ukusebenzisa: ukubekezelela iphrofayela engu-±0.05 mm endleleni egobile engqubuzana namazinga ajwayelekile okuguguleka kwama-electrode; ikilasi lentambo elingajwayelekile elicaciswe ngaphandle kokufinyelela kokulinganisa kobubanzi be-pitch. Sibuyisela impendulo echasisiwe phakathi kwamahora angu-48, okuhlanganisa nomthelela wezindleko zokwenziwa — isb., ukushintsha ukusuka ku-M12×1.25–6H ukuya ku-M12×1.25–5H kunciphisa isikhathi sokugaya intambo ngo-37% ngaphandle kokuthikameze umsebenzi. Ngezibonelo, sithumela imibiko yesihloko sokuqala ngezikena ze-CMM ezimbozwe kumamodeli e-CAD. Ngokugijima kwevolumu, yonke inkatho ihlanganisa ukulandeleka okugcwele: izingodo zokushisa, amapharamitha omshini, amarekhodi okuhlola, neziqephu ezimahhadlahhadla ebusweni - konke kugcinwe iminyaka engu-15.
Abathengi bezimboni zomhlaba wonke bakhetha i-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. hhayi ngentengo ephansi kakhulu, kodwa ngesamba sezindleko eziphansi kakhulu zobunikazi: ukwehluleka kwezinkambu ezimbalwa, izikhawu zesevisi ezinde, kanye nokufaneleka okungalindelekile. Lapho isicelo sakho sidinga ukunemba casting umphakeli ifektri amandla asekelwe kusayensi ye-alloy, hhayi nje izici zemishini - kulapho ukunemba kobukhulu kuhlangana khona nesiqiniseko sokusebenza.
