Lapho ipompo ye-hydraulic ihluleka ngaphansi kwengcindezi yamabha angu-350—noma umbhobho we-cobalt-alloy uqhekeka phakathi nenkonzo eqhubekayo yasezindaweni zikawoyela—inkinga ayiqali ngokuklama. Iqala ngengxenye eyisipele: inzalo yayo yezinto ezibonakalayo, ukuphindaphinda kwayo kobukhulu, ukuzinza kwayo okushisayo ngemva kokwelashwa kokushisa. Yingakho onjiniyela befuna imboni yokulinganisa izingxenye ezisele izixazululo aziphequluli amakhathalogi. Bacwaninga isiyalo senqubo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kusukela kulelo qiniso. Isekelwe e-Qingdao, inkampani ayithengisi “izingxenye ezisele” ezijwayelekile. Iletha izingxenye ezibaluleke kakhulu kumishini—amavalvu okucindezela, izindlu zesilinda sephampu ye-piston, ama-winch center shaft rollers—akhelwe ukubamba ukubekezelelwa okungu-±0.015 mm ekushiseni kwesevisi okungu-650°C. Sibone amakhasimende eshintsha amaketanga abahlinzeki bezigaba ezintathu ngokuzibandakanya okukodwa ngoba izingxenye zawo zephampu ye-AMS 5387 cobalt alloy 6 zifike zinokulandeleka okugcwele kwenqwaba, imibiko yokuhlolwa kwezinto ezingavuthiwe eqinisekisiwe, nokuthobelana kwe-GD&T eqinisekiswe yi-CMM—hhayi nje isiliphu sokupakisha.
Izinqumo ezintathu zobuchwepheshe zihlukanisa izinsimbi ezithembekile zokulinganisa nokushintshwa kwempahla—futhi i-QINGDAO QIANGSENYUAN ishumeka zontathu ekuhambeni kwayo komsebenzi.
- Ukulawula okubalulekile kuqala ngaphambi kokuncibilika. Ifekthri isebenzisana nemithombo ye-T800 cobalt-based alloy ingots nabalingani be-metallurgical ngaphansi kokubuyekezwa kokucaciswa okuhlanganyelwe. Yonke indawo yokushisa inosayizi wokusanhlamvu obhaliwe, ukusatshalaliswa kwe-carbide, kanye nokumelana nokugqwala kwe-intergranular nge-ASTM A952 ngayinye. Akukho okushintshiwe “kwebanga elilinganayo”. Akukho ukuqagela kwesitifiketi sokugaya.
- Imishini ayihlukanisiwe nokusakaza. Izindlu zamasilinda zithola ukufakwa kokutshalwa kwezimali *bese* ku-CNC ama-axis amahlanu—ngaphandle kokulungiswa kabusha. Kungani? Ngoba ukuhlanekezela okushisayo okuvela empumelelweni yengcindezi yangemva kokusakazwa kufanele kunxeshezelwe ohlelweni lomshini. Abahlinzeki abaningi bemishini baphonsa izikhala ezibandayo; I-QINGDAO QIANGSENYUAN ikala ingcindezi eyinsalela nge-XRD kumakhuphoni ayisampula futhi ilungisa izindlela zamathuluzi ngokufanele.
- Ukuhlola akulona isango lokugcina—kuxhunywa kuzo zonke iziteshi. Isitoko sebha ye-cobalt-nickel engenayo sithola ukuqinisekiswa kwe-spectrographic *ngaphambi* kokusikwa kwesaha. Imizimba yamavalvu omshini ihlolwa ukuvuza kwe-helium *ngemuva* kokugaywa kwendawo kodwa *ngaphambi* kokudlula. Ukuthunyelwa kokugcina akubandakanyi imibiko yobukhulu kuphela kodwa amamephu wokuqina okuncane kuzo zonke izindawo ezibucayi.
Abanye bangase baphikise ngokuthi ukuhlanganisa okuqondile kunezela izindleko. Kodwa ekusebenzeni, kuqeda izindlela zokuhluleka. Imoto eyodwa yobunjiniyela yaseNyakatho Melika i-OEM ibike ukubuyiswa kwenkambu okumbalwa okungu-40% ngemva kokushintshela kumarola we-winch shaft we-QINGDAO QIANGSENYUAN. Ukuhlaziywa kwembangela yezimpande kubonise ukuthi abahlinzeki bangaphambilini basebenzise izikhala ze-sand-cast ezinesibalo esingaguquki samaqhuqhuva e-graphite—okubangela ukuphuka kokukhathala ngaphambi kwesikhathi empandeni ye-spline. I-QINGDAO QIANGSENYUAN ishintshele ku-centrifugal casting kuleyo jiyomethri, yase yengeza ukuhlolwa kwe-ultrasonic yabo bonke ubude be-shaft. Ayikho imakhaphu eyengeziwe. I-physics nje ibhekiswe phezulu.
Umahluko wangempela uvela ezicelweni ezingajwayelekile. Isihlanganisi sephampu saseNingizimu-mpumalanga ye-Asia sidinga umlomo wombhobho onamashaneli okupholisa angaphakathi—akunakwenzeka ukubhoboza ngendlela evamile ku-AMS 5387. Esikhundleni sokwenqaba noma ukucaphuna amaviki angu-14, ithimba liphakamise ukufakwa kwe-investimenti ngokususwa kwe-ceramic core, okulandelwa ukuqedwa kwe-EDM kwesiteshi okuphumela ku-Ra 0.4 µm. Isikhathi sokuhola esiphelele: izinsuku ezingama-22. Ingxenye idlule umjikelezo oshisayo we-10,000-cycle ngaphandle kokusakazwa kwe-microcrack. Lokho akukhona ukuguquguquka. Kuwukushelela kwe-metallurgical okushadelwe ukucubungula ubunikazi.
Kusho ukuthini lokhu ngesinqumo sakho sokuthenga?
- Uma isistimu yakho yokulinganisa isebenza ngaphezu kuka-200°C noma imijikelezo izikhathi ezingaphezu kuka-500 ngosuku, funa ukulandeleka okugcwele kwempahla—hhayi nje izinombolo zokushisa, kodwa idatha yokuhlola yangempela nge-ASTM E112 kanye ne-E140 ngayinye.
- Uma i-GD&T ibiza iphrofayela yendawo noma ukuphuma kuqine kuno-0.025 mm, qinisekisa ukuthi umphakeli usebenzisa umshini wokuhlola *kanye* nesilinganiso sokubona—hhayi nje inqubo yangemuva ye-CMM.
- Uma uhlelo lwakho lokusebenza lubandakanya igesi emuncu noma ukuchayeka emanzini olwandle, qinisekisa ukuthi izimfuneko zokuqeda phezulu zihlanganisa kokubili amanani e-Ra *kanye* ne-Rz—futhi lokho kudlula kulandelwa i-ASTM A967, hhayi amadiphu kaviniga angaphansi kwesitolo.
Ukuthembeka akwenziwa endaweni yokugcina yokuhlola. Ikhiyiwe phakathi ngesikhathi kukhethwa ingxubevange, izinze esithandweni somlilo, ilondolozwe endaweni yokupholisa imishini, futhi iqinisekiswa kukho konke ukuxhumana phakathi kokwahlulela komuntu namandla omshini. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphatha isabelo sefekthri sezingxenye ezisele zemishini ngayinye njengenkontileka yobunjiniyela evaliwe—hhayi inombolo ye-oda. Lowo mqondo ushintsha amazinga okuhluleka. Ishintsha izikhawu zokulungisa. Ishintsha ukuthi singakanani isikhathi sokunciphisa isabelomali sakho somsebenzi ngonyaka ozayo.
Konjiniyela abakala impumelelo ngesikhathi phakathi kokuhluleka—hhayi ngesivinini sokuthenga—ukusesha a imboni yokulinganisa izingxenye ezisele iphetha lapho ukuqina kwenqubo kuqala.
