Uma iphampu ye-hydraulic ihluleka ngaphansi kwengcindezi yamabha angu-350, noma umbhobho we-cobalt-alloy uqhekeka ngemva kwamahora angu-800 esevisi yegesi emuncu, onjiniyela ababuzi ukuthi "Ubani owenze lokhu?" Bayabuza: “Ubani ongakulungisa—futhi aqinisekise ukuthi ngeke kuphinde kwenzeke?” Lowo mbuzo uhlukanisa abahlinzeki bempahla kozakwethu beqiniso. Enhliziyweni yalowo mehluko kukhona ikhono elilodwa: ukunemba okungaguquki, okuphindaphindwayo emisebenzini yefekthri yezingxenye zengxubevange ekhethekile—lapho kuhlangana khona i-metallurgy, i-geometry, nomsebenzi obalulekile wemishini.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphatha lokho kwehluleka—hhayi njengeziphambeko okufanele zilungiswe, kodwa njengamaphoyinti edatha ukuze kucwengwe ukulawulwa kwenqubo. Sibonile i-AMS 5387 cobalt alloy pump housings ijika ngesikhathi sokwelashwa kokushisa lapho amazinga okupholisa edlula u-12°C/min. Silinganise amarola e-center shaft asekelwe ku-T800 alahlekelwa ukuzungeza okungu-0.018 mm ngemva kwemijikelezo yetorque engu-15,000—kuphela ngenxa yokuthi ukugeleza kokusanhlamvu kwasekuqaleni kwakungahambisani nevekhtha yomthwalo. Lena akuyona imikhawulo yetiyori. Ziyimingcele ebhekwe emkhakheni ebumba sonke isibuyekezo somdwebo, wonke amasu endlela yamathuluzi, yonke indawo yokuhlola.
Amakhono amane aqinisa ukwethembeka kwawo—hhayi njengezimangalo zokumaketha, kodwa njengemiphumela elinganisekayo:
- Ubungcweti be-cobalt-nickel ngaphezu kwemininingwane. I-AMS 5387 ayikona nje “ukumelana nokugqwala.” Ukuhlakazwa kwayo kwe-carbide kuyashintsha ngomlando oshisayo. I-Foundry yabo ilawula izinga lokuqiniswa phakathi kuka-±0.8°C/isekhondi; amaseli abo e-CNC asebenzisa amathuluzi apholile ukuze abambe ubuqotho obungaphezulu obungaphansi kuka-Ra 0.4 µm kumabhore aphelile. Kungaleyo ndlela abaletha ngayo amapulaki e-cobalt alloy avala ku-420°C ngaphandle kokugwazwa—futhi kungani amakhasimende asezindaweni zikawoyela eNorth Sea ebacacisa ngeziqu zamavalvu angaphansi kolwandle.
- Ukuhlanganiswa okuqondile okuvimbela ukukhukhuleka kwe-dimensional. Abahlinzeki abaningi bakhipha izinsiza, ukwenza imishini, futhi baqedele kubathengisi abathathu abahlukene. I-handoff ngayinye ingeza ukubekezelela ukunqwabelana. I-QINGDAO QIANGSENYUAN yenza ukusakaza kwesihlabathi, ukugaya i-axis engu-5, ukwelashwa okwehlisa ingcindezi okushisa, kanye nokupholisa ngogesi endaweni eyodwa eqinisekiswe i-ISO. Izindlu zesilinda sephampu ye-piston zisuka ekuthelweni kwensimbi engaphekiwe ziye ekuqinisekisweni kokugcina kwe-CMM emahoreni angama-72—azikho izinto ezisetshenziswayo zangaphandle, akukho kuhluka kwempahla ye-batch-to-batch. Ukulandelelwa akufakiwe; ifakwe nge-laser kuzo zonke izingxenye.
- Ukuqinisekiswa kwedizayini esebenzayo—hhayi nje ukuthobela i-GD&T. Amakhasimende athumela imidwebo. Onjiniyela baphendula ngama-markups anezichasiselo: “Le chamfer engu-0.05 mm ivalela imfucumfucu emizileni yoketshezi olunamehlo aphezulu—ishintshe ngobubanzi obungu-0.2 mm.” Noma: “Ubukhulu bamanje bodonga budala ukugqagqana kwe-resonant frequency ngo-1,850 rpm. Engeza izimbambo lapha.” Lokhu akukhona ukugxeka. Kusebenza ngokubambisana okusekelwe eminyakeni engu-12 yokuhlaziywa kokwehluleka kuwo wonke ama-hydraulic, futha, nama-winch systems.
Abanye baphikisa ngokuthi umsebenzi we-alloy okhethekile udinga ukusondela kwesifunda—“Udinga onjiniyela esizeni ukuze ulungise okuphakelayo ngesikhathi sangempela.” Kodwa ukulungiswa kwesikhathi sangempela kwenzeka ngaphambi kokuthi ukusika kuqale. Isofthiwe yabo yokulingisa yangaphambi komshini imodeli yokwakheka kwe-chip ku-T800 ingxubevange ngama-engeli amareki ahlukahlukene, ibikezela ukuguga kwamathuluzi phakathi kuka-3% wempilo yangempela. Lapho ikhasimende laseYurophu lidinga ama-valve okucindezela okungajwayelekile angama-220 emasontweni ayi-11, ibhodlela lalingelona umthamo—bekuqinisekisa i-microstructure homogeneity kuwo wonke ama-casting angu-16. Isixazululo sabo? Ilebhu ye-metalography esesayithi + imephu ye-EDS ezenzakalelayo. Yonke inkatho yaphasisa ukuqinisekiswa kosayizi wokusanhlamvu kwe-ASTM E112 ngaphambi kokuba kuqale ukugaywa kwemishini enzima.
Lesi siyalo siyakala—kodwa kuphela lapho okubalulekile kuhlala kungashintshile. Abajahi ivolumu. Balungiselela ukuphindaphinda: u-opharetha ofanayo, umshini ofanayo, ukugxilisa okupholile okufanayo, umjikelezo ofanayo wokuhlanza ngemva kwenqubo. Yingakho ukukhishwa kwensimbi yabo kufezwa engaguquki amandla okudonsa angu-780 MPa ±12 MPa—hhayi “kufika ku-780 MPa.” Kungani izisekelo zabo zephampu yensimbi engagqwali zibambe isicaba phakathi kuka-0.03 mm ngaphezu kuka-600 mm—kuqinisekiswe i-laser tracker, hhayi nje i-CMM. Kungani imibhobho yabo ye-cobalt alloy isinda emijikelezweni eshisayo engu-14,000 kuma-turbines okubuyisela udoti ngaphandle kwe-microcracking.
Imboni ekhethekile yezingxenye zengxubevange izuza ukwethenjwa hhayi ngokuthembisa ukuphelela—kodwa ngokubhala ngokuqondile lapho ukungapheleli kuhlala khona, bese kuba ubunjiniyela abakuzungezile. I-QINGDAO QIANGSENYUAN TECHNOLOGY ayikufihli ukuhlukahluka. Bayenza imephu: ama-thermal gradients ekubunjweni kokubunjwa, ama-vector achezuka amathuluzi ekugayweni kwe-deep-pocket milling, amanani e-hydrogen pickup ngesikhathi se-electropolishing. Imibiko yabo yekhwalithi ayifaki kuhlu lokudlula/ukuhluleka. Abonisa amanani e-delta ngokumelene namajika ayisisekelo—ukuze amakhasimende abone nje ukuthi *uma* ingxenye ihlangabezana ne-spec, kodwa *ingakanani imajini esele* ngaphambi komkhawulo wokusebenza.
Ikusasa aliphathelene nemishini emikhulu noma ama-spindle asheshayo. Imayelana nezihibe zempendulo eziqinile phakathi kokusebenza kwenkambu kanye nemingcele yenqubo. Njengamanje, ithimba labo le-R&D lixhumanisa amasiginesha okudlidliza asuka kumarola asetshenzisiwe e-winch center shaft anamamephu okucindezeleka ayinsalela avela ezikeneni zawo ze-XRD. Ngonyaka ozayo, leyo datha izoqhuba ukukhiqizwa kwendlela yamathuluzi eguquguqukayo—ukungasebenzisi ubukhulu obuvamile, kodwa kumaphrofayili okuguqulwa komthwalo wesevisi abikezelwe. Yilapho ukwethembeka kuyeka khona ukuba yithagethi-futhi kuba umphumela olinganisekayo.
