Uma onjiniyela becacisa ingxenye okufanele ibambe ukubekezelela okungu-±0.01 mm ngaphansi kwengcindezi ye-hydraulic yamabha angu-350—futhi isinde emijikelezweni engu-10,000+ odaka olubi—abadingi nje isisekelo. Badinga i Imboni yokukhipha utshalomali ye-IMPRO ephatha i-metallurgy njengekhodi nokuzinza kwe-dimensional njengomthetho wenkontileka.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenzisa isikhungo esisodwa esinjalo e-Qingdao—hhayi njengesitolo sensimbi esijwayelekile, kodwa njengozakwethu onembayo wezingxenye ezibalulekile zemishini lapho ukwehluleka kungambi eqolo—kuyinhlekelele. Sibone amakhasimende ebuya izikhathi ezintathu nomdwebo wezindlu wephampu ye-cobalt ye-AMS 5387 ye-cobalt alloy efanayo: okokuqala okokusebenza kwezinto endaweni engaba yi-valve, okwesibili ngenxa ye-microcracking ngemva kokwelashwa kokushisa, okwesithathu ngenxa yokuthi ukuqedwa kwendawo akuhlangabezani nezinkomba zokulinganisa ukugeleza. Ngaso sonke isikhathi, imbangela yayingeyona "ikhwalithi yokusakaza" -kwakuwukungalungi kahle phakathi kokuziphatha kwe-alloy, ukwakheka kwesango, kanye nokulandelana kokunciphisa ukucindezeleka kwangemva kokusakazwa. Yilapho le mboni ihambisa khona.
Kungani ama-alloys e-cobalt-nickel efuna okungaphezu nje “kokutshala imali”
Abahlinzeki abaningi baphatha i-AMS 5387 noma i-T800 njengelinye ibanga eshidini elicacisiwe. Eqinisweni, lawa ma-alloys ashwabana ngo-17% ngaphezu kuka-316 angenasici ngesikhathi sokuqina, athuthukise ama-gradients ashisayo abe ngu-3× aqine kakhulu ezingxenyeni ezinodonga oluncane, futhi amelana nomshini kangangoba amathuluzi e-carbide agqoka ngokushesha okungama-40% uma ukwelashwa kwangaphambi kokushisa kunganqunyelwe isikhathi. Sikulinganise lokhu—ezindlini zangempela zesilinda sephampu ye-piston eyakhelwe isevisi kawoyela negesi yasogwini.
I-QINGDAO QIANGSENYUAN ayinikezi ukufaneleka kwe-alloy. Ithimba labo lobuchwepheshe liqinisekisa ngokuhlanganyela amaqoqo ezinto ezingavuthiwe nabahlinzeki abaqinisekisiwe—ukulandelela ukusatshalaliswa kosayizi wokusanhlamvu, ukuhlakazeka kwesigaba se-intermetallic, nokuqukethwe komoya-mpilo kuze kufike ku-15 ppm. Lapho ikhasimende lithumela umbhobho we-T800 onokuguguleka ngaphambi kwesikhathi emphinjeni, sawulandelela emuva emvuleni engahambisani ne-niobium carbide endaweni eyodwa yokushisa. Ukulungisa? Ukulungisa isilinganiso serempu yesisombululo ngo-0.8°C/sec—kanye nokubamba imibhalo yawo wonke uhlaka lwekhilogremu.
Leli zinga lokulawula lisebenza kuphela ngenxa yabo Imboni yokukhipha utshalomali ye-IMPRO ihlanganisa izinyathelo zenqubo ezinye i-silo: i-geometry yephethini ye-wax iqinisekiswa ngokumelene nezindlela zamathuluzi ze-CNC *ngaphambi* kwesakhiwo samagobolondo; imijikelezo yokwelashwa kokushisa ivumelaniswa nemishini yokugcina; amapharamitha wokuqeda phezulu (Ra ≤ 0.4 μm) aqinisekiswa kusetshenziswa i-optical profilometry—hhayi nje ama-tactile probe—ngoba ukugeleza okunesiyaluyalu kufuna ukuphindaphinda kwe-sub-micron.
Ukuhlanganiswa okuqondile akuyona i-buzzword-umshuwalense wokubekezelela
Abanye abathengisi bacaphuna ukusakaza kuphela, bese kuba imishini engaphansi kwenkontileka ezitolo ezintathu ezahlukene. Lokho kwethula iphutha elinqwabelene: ukuncipha kokuncipha + i-machining fixture shift + thermal distortion = izingxenye ezilingana ku-CMM kodwa ezibophezela ekuhlanganisweni. Kwa-QINGDAO QIANGSENYUAN, ithimba lonjiniyela elifanayo liphethe uchungechunge oluphelele—kusuka encazelweni ye-GD&T ocingweni lokubuyekeza umdwebo ukuya ekuhlolweni kokugcina kokusebenza ebhentshini le-hydrostatic.
Silandelele imizimba ye-valve ye-pressure engu-42 kuwo wonke ama-run amabili okukhiqiza. Lezo ezifakwe ngomshini ngaphakathi endlini zibonise ukuphindaphinda okungu-92% ezindaweni ezibucayi zokuvala. Labo abaphothule umsebenzi wangaphandle behle bafinyelela ku-68%. Umehluko? Amaphutha okudlulisa idatha yokulungisa kuya kukulungisa anesilinganiso esingu-0.018 mm—anele ukufaka engozini ukuvala okuqinile kwebhamuza kubha engu-250.
- I-CNC machining: 5-axis contouring kanyekanye yamaphaseji angaphakathi ayinkimbinkimbi ezisekelweni zephampu
- Ukwelashwa kokushisa: I-vacuum annealing ngemephu yesikhathi sangempela se-thermocouple ngaphakathi komthwalo ngamunye
- Ukuqeda: I-Electropolishing yokumelana nokugqwala *kanye* nobushelelezi obuncane—kuqinisekiswe yi-SEM imaging
Asikho isinyathelo esinikezwayo ngaphandle kokulandeleka okubhaliwe: izinombolo zenkatho, ama-ID omsebenzisi, amalogi okulinganisa umshini, nemibiko ye-CMM efakwe kungobo yomlando ngamazinga we-AS9102—ngisho nama-oda okungewona awe-aerospace. Ngoba lapho i-winch center shaft roller ihluleka ukuphakamisa phakathi nendawo emgodini wezimayini, "silandele inqubo" akwanele. Udinga ubufakazi bokuthi *yini* inqubo—nokuthi isebenze kanjani kahle.
Ukulethwa komhlaba wangempela kusho ukuphendula konjiniyela—hhayi nje amadethi ekhalenda
“Ukulethwa ngesikhathi” akusho lutho uma ukuthunyelwa kokuqala kufika nokuzwakala kwentambo okungalungile kupulaki ye-cobalt alloy. I-QINGDAO QIANGSENYUAN yakhela ukuqina kweshejuli kubunjiniyela—hhayi ezokuthutha. Abaphathi bephrojekthi yabo abagcini nje ukulandela isikhathi sokuhola; bahlaba umkhosi izingozi zokwenziwa *ngaphambi* kokuqala kwamathuluzi.
Ngonyaka odlule, iklayenti laseYurophu lahambisa i-GD&T ebuyekeziwe yebhulokhi enama-hydraulic manifold. Ithimba lethu libone ukuthi ukubekezelela indawo ethile (±0.025 mm) ku-datum C kuzodinga ukugaywa ngemva kokusakaza—kwengeza u-$1,200/iyunithi nokulibaziseka kwamaviki angu-3. Esikhundleni salokho, bahlongoze ukulungisa ukuphrinta okuyinhloko ukuze kuhanjiswe i-datum endaweni yomshini, kuzuzwe ukuqondanisa okufanayo kokusebenza ngezindleko eziphansi ezingama-40%. Iklayenti ligunyaze emahoreni angama-48.
Lokhu kwenzeka ngoba onjiniyela babo bakhuluma kokubili i-Foundry kanye ne-fluid dynamics. Bayazi ukuthi kungani i-offset engu-0.1 mm ku-engeli yokukhipha umlomo wombhobho ishintsha ukusebenza kahle kwephethini yesifutho ngo-11%. Bahlole ama-flow coefficients kumajiyometri angu-17 we-cobalt alloy—hhayi kusukela ekulingiseni kuphela, kodwa ngamabhentshi okugeleza alinganiselwe asebenzisa uketshezi lwangempela lokusebenza.
Uma uthola izingxenye zensimbi ezinemba okuphezulu lapho ukusebenza kuncike kubuqotho besakhiwo se-microstructure, hhayi nje ubukhulu obukhulu, ukukhetha akukho phakathi kwabathengisi-kuphakathi kokuqagela nobufakazi. An Imboni yokukhipha utshalomali ye-IMPRO ayithembisi ukuphelela. Iletha imiphumela elandelekayo, ephindaphindwayo, eqinisekisiwe ngokusebenza—ingxenye eyodwa ebalulekile ngesikhathi.
