Lapho onjiniyela becacisa izingxenye zensimbi engagqwali zamavalvu asebenza ngogesi, izindlu zephampu, noma amasistimu ewintshi asogwini, abagcini nje ngokukhetha into ethile—babheja ukuqina kwe-dimensional ngaphansi kwengcindezi yamabha angu-300, ukumelana nokugqwala ezindaweni ezicebile nge-chloride, kanye nobuqotho besakhiwo ngemva kokwelashwa kokushisa. Yingakho ukhetha okulungile insimbi engagqwali ingxenye ifektri ayimayelana nezinombolo zekhathalogi noma izikhathi zokuhola zodwa. Imayelana nekhono elifakazelwe ngamaalloyi e-cobalt e-AMS 5387, ukuthobela kwe-GD&T okuphindaphindwayo kumajenali we-Ø0.005 mm shaft, kanye nokulandeleka kuze kufike eqoqweni elincibilikayo le-F51 duplex steel stainless steel.
Ukunemba Kuqala Lapho Ukusakaza Kuhlangana Nomshini
Abahlinzeki abaningi bahlukanisa ukusakaza kanye nemishini ye-CNC—ukukhipha eyodwa noma kokubili. Lokho kudala izikhala ze-handoff: i-warpage esuka ekupholiseni okungalingani iyabonwa kuze kube yilapho ihlolwa okokugcina; ukungqubuzana kokuphela kwendawo kubukela phansi ukusebenza kwezimpawu; ukungafani komlando wokushisa kubangela ukukhathala ngaphambi kwesikhathi ezingxenyeni zephampu ezinomjikelezo omkhulu. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., ukulingisa kanye nokwenza imishini kwenzeka ngaphansi kophahla olulodwa oluqinisekiswe i-ISO. Siphonsa izindlu zensimbi nensimbi engagqwali sisebenzisa utshalomali kanye nezinqubo zesihlabathi ezilinganiselwe ukuze zibe ne-porosity ephansi—bese sizimshini ngokushesha, kuyilapho ukucindezeleka okuyinsalela kusalokhu kubikezelwa. Akukho ukulinda ukwelashwa kokushisa okuvela eceleni. Akukho ukulungisa okwethula iphutha lokuqongelela. Iqembu elilodwa liphethe indlela egcwele esuka kwinsimbi encibilikisiwe iye engxenyeni eqediwe.
Lokhu kuhlanganiswa okuqondile kuletha izinzuzo ezilinganisekayo. Ezindlini zamasilinda ephampu ye-piston ezidinga ukuzungeza okungu-±0.01 mm kuwo wonke ubude obungu-250 mm, inqubo yethu yasendlini inciphisa ukuhluka okuphelele ngo-37% uma kuqhathaniswa nokugeleza kokusebenza komphakeli ohlukanisiwe. Sibone amakhasimende eshintsha phakathi nephrojekthi ngenxa yokuthi umphakeli wawo wangaphambili akakwazanga ukubekezelela indawo kuma-bores amathathu agxilile—ngalinye lenziwe ngomshini ngokusetha okuhlukene kuzo zonke izindawo ezimbili. Sikwenza ngokusetha okukodwa, kumshini wokugawula we-5-axis onokuhlola okuhlanganisiwe nesinxephezelo sesikhathi sangempela esishisayo.
Akuzona Zonke Insimbi Engagqwali Ezilinganayo—Futhi Nezimboni Eziyicubungulayo Azifani
Ezinye izimboni ziphatha “insimbi engagqwali” njengebanga elilodwa. Abakwenzi. Umzimba wamavalvu angu-316L wamaphampu ebanga lokudla udinga ukushintshwa okuhlukile, ukulawula okusanhlamvu, kanye nemikhawulo yokufaka kunendlu ye-F22 chrome-moly yesevisi yegesi emuncu. Okubi nakakhulu, izitolo eziningi azinawo amaphrothokholi okuqinisekisa i-metallurgical—zithembele kuzitifiketi zokugaya kuphela, ngaphandle kokuqinisekisa ubulukhuni bangempela, okuqukethwe kwe-ferrite, noma ukumelana nokugqwala kwe-intergranular post-weld.
Sivivinya yonke inkatho yensimbi engagqwali engenayo—hhayi nje amakhemikhali, kodwa ukuqinisekiswa kokudlula kwe-ASTM A967, ukuhlaziya usayizi wokusanhlamvu we-ASTM E112, futhi lapho kudingeka khona, ukuhlolwa kokuhlasela kwe-ASTM A262 Practice E intergranular. Lapho ikhasimende laseYurophu lidinga izingxenye ze-UNS S32750 super duplex zamamojula okulawula ulwandle olungaphansi kolwandle, senze ukuhlola okugcwele komthelela we-Charpy kokuthi -46°C ngaphambi kokuthi kuqale ukusebenza. Kungani? Ngoba umsebenzi obandayo ngesikhathi sokuphenduka ungazwela indawo ethinteke ukushisa. Silungisa amanani okuphakelayo, ukugeleza kokupholisa, kanye nejiyomethri yamathuluzi ngokusekelwe kumephu yesikhathi sangempela esishisayo—hhayi imithetho evamile yaphansi yesitolo.
Leso siyalo sidlulela kuma- superalloys. I-AMS 5387 cobalt-nickel nozzles ifuna izindawo ezingenazo i-carbide kanye nokulawulwa kabusha kokwenziwa kabusha kwekristalu. Sisebenzisa ukugaya okunengcindezi ephansi ngamasondo edayimane, kulandelwa i-electropolishing eqinisekisiwe nge-ASTM B912 ngayinye. Amakhasimende asitshela ukuthi lokhu kususa ukwehluleka kwenkundla abekubone kwenye indawo—ikakhulukazi ezinhlelweni eziludaka olubi lapho imifantu emincane iba amasayithi okuqalisa ukuguguleka.
Isiko Alisho Ukuyekethisa—Lisho Ingozi Elawulwayo
“Okwezifiso” kuvame ukukhombisa ukungaqiniseki: izingcaphuno ezinde, imigqa yesikhathi engacacile, idizayini yokukhiqiza (i-DFM) izimanga ngemuva kwesikhathi ku-prototyping. Kodwa izingxenye zangokwezifiso ziyaphumelela lapho ukwenziwa kushumekwe kusenesikhathi—akuxoxiswana ngakho ngemva kokuqala kokusetshenziswa kwamathuluzi.
Siqala yonke iphrojekthi ngokuqinisekisa umdwebo—hhayi nje ukuhlola ubukhulu, kodwa ukwenza imephu izindawo ezisebenzayo ezibucayi ngokumelene nokuqedwa kwendawo okungafinyeleleka, ukuhlonza izindawo zokuxoxa ezingaba khona ezigabeni ezinezindonga ezinodonga oluncane, nokuhlaba umkhosi izingcingo ze-GD&T ezingqubuzana nezindlela ezijwayelekile zokubopha. Ngekota edlule, sihlabe umkhosi imfuneko yokuba flat engu-±0.002 mm kusisekelo sephampu yensimbi engenasici engu-400 mm × 200 mm. I-spec yasekuqaleni ithathwa njengokugaya i-granite-slab. Senze isiphakamiso se-aneal eqeda ingcindezi + ukulandelana kokugaya okunembayo esikhundleni salokho—ukunciphisa izindleko ngo-22% nokulethwa ngezinsuku eziyi-11, ngaphandle kokudela ukusebenza kokusebenza.
- Siqinisekisa ukulandeleka kwezinto kuwo wonke ama-oda—inombolo yokushisa, imibiko yokuhlola, namarekhodi okuhlola alondolozwe iminyaka engu-10+
- Sihlola ukuhlolwa kwe-CMM ezigabeni ezintathu: ukuhlanza kwangemva kokubi, ukuqeda, kanye nokuhlanza kwangemva kokugcina
- Sihlinzeka ngamaphakheji e-FAI aphelele—okuhlanganisa nezitifiketi zezinto ezingavuthiwe, izinhlaka zenqubo, nemibiko ye-CMM yesihloko sokuqala—ngaphambi kokukhipha umkhiqizo.
Isilinganiso Sangempela Sefekthri Yengxenye Yensimbi Engagqwali
Akukona ukuthi mangaki amathani owaphonsa ngenyanga. Kungakhathaliseki ukuthi indlu yakho ye-valve yokucindezela idlula ukuhlolwa kwe-hydrostatic ku-1.5 × ingcindezi yokusebenza-ngaphandle kokuvuza okuncane ku-interface ye-flange. Ukuthi ipulaki yakho ye-T800 cobalt alloy iyasinda emijikelezweni engu-10,000 kusevisi yezinga lokushisa eliphezulu le-H₂S. Ukuthi i-winch centre shaft roller yakho yemoto yobunjiniyela igcina ubulukhuni bobuso ngemva kwamahora angu-500 wokuchayeka kwesifutho sikasawoti.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. wakha lezo zingxenye-hhayi njengokuhlukile, kodwa njengomkhuba ojwayelekile. Sisebenza ngokukhethekile kulokho abanye abakugwemayo: amajiyometri ayinkimbinkimbi kuma-alloys asebenza kanzima emshinini, ama-alloy aqinile lapho ukuncipha nokuchezuka komshini kufanele kukhanselwe—hhayi okuhlanganisiwe—kanye nezinto ezibalulekile lapho ukwehluleka kungeyona inketho.
Uma ingxenye yakho elandelayo yensimbi engagqwali idinga okungaphezu kokucaphuna—udinga uzakwethu okhuluma i-metallurgy, i-GD&T, nokuthembeka kokusebenza emshweni ofanayo—yilapho kuqala khona ukukhiqiza ukunemba. Futhi yilapho izixazululo ezenziwe ngokwezifiso zithola khona igama lazo.
