Lapho amasistimu we-hydraulic ehluleka ngaphansi kokucindezela kwamabha angu-350, lapho izindlu zephampu ziqhekeka ngemva kwamahora okusebenza angu-12,000, noma lapho imibhobho ye-cobalt-nickel iguguleka ngokushesha kunalokho obekulindelwe—onjiniyela abasoli umklamo. Bakulandelela bakubuyisele esinqumweni esisodwa: ubuqotho obuphathekayo obumataniswe nokuthembeka kobukhulu ku- ifektri yezingxenye ze-nickel-based alloy mechanical.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uye wachitha iminyaka engaphezu kweshumi exazulula leyo nkinga ncamashi—hhayi ngombono, kodwa esitolo. Sibone ukusakazwa kwe-AMS 5387 kungqubuzana phakathi nokwelashwa kokushisa ngenxa yesakhiwo sokusanhlamvu esingaguquki. Sisebenze kabusha amarola e-T800 alloy center shaft izikhathi ezintathu ngenxa yemifantu emincane efihlwe ngaphansi. Lokhu akukona okucatshangelwayo. Ziyizifundo zenkambu ezilolonga indlela esenza ngayo, senza, futhi siqinisekise zonke izingxenye.
Kungani ama-alloys asekelwe ku-nickel efuna okungaphezu kwamandla e-CNC
Ama-alloys asekelwe ku-nickel njenge-Inconel 718, i-Hastelloy C-276, ne-AMS 5387 amelana nokugqwala futhi agcina amandla angaphezu kuka-650°C—kodwa futhi asebenza kanzima ngokushesha, angakwazi ukushisa kahle, futhi agqoke amathuluzi okusika kabuhlungu. Isitolo esijwayelekile se-CNC asikwazi ukubamba ukubekezelelwa okungu-±0.01 mm kusilinda se-piston pump cylinder engu-420-mm-diameter eyenziwe nge-T800 alloy ngaphandle kwamasu akhethekile endlela yamathuluzi, imijikelezo yokusimamisa okushisayo, kanye ne-metrology eqhubekayo.
Yingakho ukuhlanganiswa okuqondile kubalulekile. Esikhungweni sethu se-Qingdao, ukulingisa akukhishelwa ngaphandle. Ukubunjwa kwesihlabathi nokufaka utshalomali kwenzeka ngaphansi kophahla olulodwa—eduze kwezikhungo zokumaka ama-multi-axis zilinganiswa nsuku zonke. Silawula izinga lokushisa lokushisa kwesikhunta, izinga lokuqiniswa, kanye nokukhululeka kwengcindezi yangemva kokusakazwa ngaphambi kokusika kokuqala. Awekho ama-handoffs. Akukho ukuhluka kwe-batch-to-batch esikhaleni se-dendritic. I-microstructure ephindaphindiwe-futhi yilapho ukuzinza kwe-dimensional kuqala khona.
Sihlola lokhu nsuku zonke: ikhasimende licele amapulagi angu-18 afanayo we-cobalt alloy for high-pressure fuel manifolds. I-Batch 1 iphumelele ukuhlolwa kwe-CMM kodwa yehluleka ukuhlola ukuqhuma kubha engu-412. I-Micro-CT yembule i-porosity ecashile eduze kwehlombe elivalekayo—elingabonakali ngokugezwa kwendawo. Silungise ukwakheka kwesango, sehlisa izinga lokushisa lokuthulula ngo-23°C, futhi sengeza nokudlidliza kwe-ultrasonic ngesikhathi sokuqina. I-Batch 2 ibambe amabha angama-487. Lelo zinga lokulawula liba khona kuphela lapho onjiniyela abakhangisayo nabasebenza ngomshini behlala ndawonye ngesikhathi sokubuyekezwa kwe-DFMA.
Kusho ukuthini "ukunemba" ezingxenyeni ezibalulekile zemishini
Ukunemba akukhona nje ukubekezelelana okuqinile. Ukuqondanisa okusebenzayo phakathi kwejometri, i-metallurgy, nendawo yesevisi. Umzimba we-valve yokucindezela kufanele uvaleke—kodwa futhi kufanele uphile lapho uhamba ngebhayisikili elishisayo ngaphandle kokuqhekeka esixhumi esibonakalayo sokushisela. I-winch center shaft roller kufanele ijikeleze ngokushelela—kodwa ukuqina kwayo kwendawo kufanele kudlule i-HRC 52 *futhi* igcine ukuqina kobuso obungaphansi ukuze imelane nokuchitheka.
Yingakho iphrothokholi yethu yekhwalithi ishumeka ukuqinisekiswa ezindaweni ezine okungaxoxiswana ngazo:
- Ukuqinisekiswa kwezinto ezingavuthiwe: Yonke ikhoyili noma ingot ithwala ama-MTR agcwele, okuhlanganisa ukuhlaziywa kwe-spectrographic kanye nemibiko yosayizi wokusanhlamvu—hhayi nje isitifiketi sebanga
- Ukuhlolwa kwe-CMM okungaphakathi kwenqubo: Ngemva kokugoqa, ukuqeda kancane, nokuqeda—emshinini ofanayo olinganisiwe, kusetshenziswa uhlelo olufanayo lwedatha
- Ukuhlola okusebenzayo: Ama-valve okucindezela ahlolwe ku-1.5 × ingcindezi elinganiselwe; izindlu zephampu zi-spin-balanced futhi zihlolwe ukuvuza nge-helium mass spectrometry
- Ukulandeleka okugcwele: Ingxenye ngayinye ixhuma kunombolo yayo yokushisa, inguqulo yohlelo lomshini, i-ID yomsebenzisi, nesitembu sesikhathi sokuhlola
Lokhu akubona ubunjiniyela obudlulele. Igwema izindleko zesikhathi sokuphumula ezingama- $280,000 lapho isilinda esisodwa esiqhekekile simisa iphampu yodaka ye-offshore oil rig amahora angama-72.
Lapho ukwenza ngokwezifiso kuyeka ukuba yingozi—futhi kuqala ukuletha i-ROI
Abanye abahlinzeki baphatha izingxenye ezingajwayelekile njengezihlukile. Sibaphatha njengamathuba okuqeda izindlela zokwehluleka. Ngonyaka odlule, i-OEM yase-Europe yasilethela umdwebo wenozili yangokwezifiso ye-AMS 5387 eneziteshi zokupholisa ze-asymmetric. Umthengisi wabo wangaphambili ucaphune amasonto ayi-14 futhi wenqaba isikweletu ngokuchezuka okungaphezu kuka-±8%. Sisebenzise ukulingisa okushisayo, saklama kabusha ama-baffles angaphakathi ukuze sithuthukise ukufana kwesivinini, futhi salethwa emavikini angu-9—ngokuchezuka kokugeleza kukalwa ku-±2.3% kuwo wonke amayunithi angu-12.
Kanjani? Ngokuphatha i-GD&T hhayi njengephepha, kodwa njengolimi olusebenzayo. Uma umdwebo ucacisa ukubekezelela indawo kwe-Ø0.05 mm ngokuhlobene ne-axis yedatha, siqinisekisa leyo eksisi *ngaphambi* komshini—hhayi ngemva kwalokho. Uma ukuphela kwendawo kubiza u-Ra 0.4 µm ebusweni obuvalekayo, sisebenzisa ukuguqulwa kwedayimane—hhayi ukugaya—ngoba ukugaya kubangela umonakalo ongaphansi komhlaba oqala ukuqhekeka kokukhathala ngaphansi kokulayisha okujikelezayo.
Leso siyalo siyakala. Kungakhathaliseki ukuthi udinga amavalvu omfutho we-prototype amahlanu noma izisekelo zephampu ezingu-300 ngekota ngayinye, ukuhamba kwethu okuthambile kuyakhiya ngesikhathi somjikelezo, isivuno sezinto ezibonakalayo, nesivuno sephasi yokuqala—ngaphandle kokudela ukulawulwa kwensimbi.
Ukukhetha uphathina—hhayi nje umphakeli—wezingxenye zemishini ezisekelwe ku-nickel
Ilungelo ifektri yezingxenye ze-nickel-based alloy mechanical ayihlanganisi nje imininingwane. Ibikezela lapho imininingwane isilela khona. Iyazi ukuthi amandla e-AMS 5387 ehla ngo-12% uma isixazululo se-annealing sidlula i-1180 ° C-ngisho noma i-MTR ithi "ngaphakathi kwebanga." Iyaqonda ukuthi i-sand-cast T800 idinga amapharamitha ahlukile wokudubula kunezinhlobo zokutshala imali—ngoba ukusatshalaliswa kwengcindezi eyinsalela kuyehluka.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kuleyo mpambana-mgwaqo yesayensi yezinto kanye nokukhiqiza ukunemba. Asizigcini izikhala ezijwayelekile. Sicubungula ukulandelana komsebenzi wengxenye yakho—hhayi umthamo wethu womshini. Indawo yethu ethobela i-ISO e-Qingdao iletha izingxenye ze-cobalt-nickel eziqinisekisiwe eNyakatho Melika, eYurophu, naseNingizimu-mpumalanga ye-Asia—hhayi njengezinto zekhathalogi, kodwa njengezixazululo eziqinisekisiwe.
Uma ngabe iphrojekthi yakho elandelayo ibandakanya ukucindezela okuphezulu, izinga lokushisa eliphezulu, noma izindawo ezigqoka kakhulu—futhi udinga izingxenye ezisebenza ngendlela eklanywe ngayo, eshintshashintshayo ngemva kokushintsha, unyaka nonyaka—qala ngokulandeleka kwezinto, ukuqina kobukhulu, nokuqinisekiswa komhlaba wangempela. Hhayi izincwajana. Hhayi izithembiso. Ukubulawa okuqinisekisiwe.
