Lapho onjiniyela becacisa izingxenye zengxube ye-nickel esekelwe ku-nickel, abagcini nje ngokukhetha into ethile—bazibophezela ekusebenzeni ngaphansi kwengcindezi, ukushisa, nokugqwala. Ukungalingani okukodwa ekuzinzeni kohlangothi noma i-microstructure kungase kudlulele ekuhlulekeni kwephampu, ukuvuza kwevalvu, noma isikhathi sokuphumula esingahleliwe kumasistimu asebenza ngamanzi noma okokusebenza kwendawo kawoyela. Kungakho ukuthola ku-a i-nickel based alloy parts factory akuphathelene nentengo yodwa-imayelana nokuziphendulela kwe-metallurgical, isiyalo senqubo, kanye nokuphendula okuqinisekisiwe emijikelezweni yokucindezeleka yomhlaba wangempela.
Kungani i-AMS 5387 ne-T800 Idinga Okungaphezu Kwemishini Ejwayelekile
Sibone amaphrojekthi amaningi kakhulu esima esigabeni se-prototype—hhayi ngenxa yamaphutha edizayini, kodwa ngenxa yokuthi umphakeli akanalo ulwazi lwama-cobalt-nickel superalloys. I-AMS 5387 cobalt alloy 6 kanye nezinto ezisekelwe ku-T800 aziphathi njenge-316 engenasici. Basebenza kanzima kanzima. I-conductivity yabo ye-thermal iphansi. Amathuluzi okusika aguga ngokushesha ngaphandle kokuthi amanani okuphakelayo, ukulethwa kokupholisa, kanye nejiyomethri yamathuluzi kufaniswe ngokunembile nobulukhuni obukhethekile benqwaba kanye nesakhiwo sokusanhlamvu.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke imbobo ye-AMS 5387 noma i-T800 center shaft roller iqala ngokulandeleka kwempahla eluhlaza okuqinisekisiwe—hhayi nje izitifiketi zokugaya, kodwa amarekhodi okwelashwa okushisa kweleveli enkulu abhekiselwe kwamanye amalogi okusakaza. Senza ukuhlaziya okungenayo kwe-spectrographic kuwo wonke amakhoyili noma ingot. Uma okuqukethwe kwekhabhoni kukhukhuleka ku-±0.02%, siyavalela futhi siphinde sihlole ngaphambi kokulayisha ku-CNC noma emigqeni yokutshala imali. Lokhu akukona ukudlula ngokweqile. Kuyindlela esibamba ngayo ukubekezelela okungu-±0.005 mm kumasilinda wepompo yepiston engu-200 mm asebenza kubha engu-420.
Ukuhlanganiswa kwethu okuqondile kwenza umehluko: ukulingisa, ukwenza imishini, nokuqeda kwenzeka ngaphansi kophahla olulodwa oluthobela i-ISO. Awekho ama-handoffs asho ukuthi akukho ukukhukhuleka phakathi kwe-as-cast geometry kanye nokuthobelana kokugcina kwe-GD&T. Sikhipha ngokuqondile isihlabathi esiluhlaza noma izikhala zokutshala imali—akukho ukulungisa okwesibili okwethula iphutha lokuqondanisa. Kumajiyometri angajwayelekile—njengamarola e-asymmetric winch center shaft ane-spline edidiyelwe namajenali ane-bearing—sisebenzisa ukugaya ngasikhathi sinye i-5-axis ne-in-process laser probing ukuze siqinisekise ukwethembeka kwekhonta ngaphambi kokuyiqaqa.
Lapho “Inkombiso” Kusho Ubambiswano Lobunjiniyela—Hhayi nje Ukuhumusha kwe-CAD
Abanye abakhiqizi baphatha ama-oda wangokwezifiso njengokuphambuka kumakhathalogi ajwayelekile. Sibathatha njengokuxazulula izinkinga ngokubambisana. Lapho i-OEM yepompo yase-Europe isithumelela umdwebo wepulaki ye-AMS 5387 enerediya yangaphakathi ephambanayo emithathu kanye nemfuneko yokuqedwa kwengaphezulu engu-0.8 µm Ra, umbuzo wethu wokuqala bekungekhona ukuthi "Ingabe ungagunyaza ikhotheshini?" Bekuwukuthi "Iyiphi imodi yokwehluleka ozama ukuyivimba?"
Kuvele ukuthi ukuguguleka kwe-cavitation enhlanganweni ye-radius kubangele ukwehluleka kwenkambu ngemva kwamahora angu-1,200. Ngakho-ke siphakamise i-electropolish yangemva komshini—eqinisekiswe yi-SEM imaging—ukuze isuse izinyembezi ezincane ezishiywe ukugaya okuvamile. Siphinde saphakamisa ukuthi kushintshwe ukulandelana kokwelashwa kokushisa: i-anneal yesixazululo *ngaphambi* komshini wokugcina, bese ukuguga *ngemuva*, ukuze kukhiywe amandla aqinile ngaphandle kokuphazamisa ukusebenza kahle. Ingxenye iphumelele ukuhlolwa kwempilo okusheshisiwe kwamahora angu-3,500. Lowo mphumela uqhamuke ekuqondeni kwesizinda—hhayi nje emandleni.
Leli zinga lokuzibandakanya liyasebenza ngoba ithimba lethu lihlanganisa onjiniyela bezinhlelo zokusebenza abaye basekela isistimu ye-hydraulic eyakha eNyakatho Melika naseNingizimu-mpumalanga Asia. Bakhuluma kahle nge-GD&T. Bahlaba umkhosi izingozi zokwenziwa kusenesikhathi—njengokucacisa irediyasi engu-0.2 mm endaweni eyimpumputhe engu-12 mm ejulile lapho ukufinyelela kwethuluzi kukhawulela ukuphuma kwe-chip. Asilindi ingxenye yokuqala enqatshiwe ukuze siqale leyo ngxoxo.
Ukulawulwa Kwekhwalithi Okungami embikweni we-CMM
Umbiko we-CMM uqinisekisa ubukhulu. Akuqinisekisi ubuqotho bokusebenza. Ngakho inqubo yethu yokuhlola ijula kakhulu: ukuqinisekiswa kwezinto ezingenayo, ukuqina kwemephu okungaphakathi kwenqubo ngamaphoyinti amathathu ekubunjweni ngakunye, ukuskena okugcwele okugcwele okugcwele kwezindawo zokuvalwa okubalulekile, nokuhlola kokugcina kokusebenza—okuhlanganisa nokuhlola ukubola kwengcindezi kuwo wonke ama-valve afika kumabha angu-600.
- Sigcina ukulandeleka okugcwele: inombolo yokushisa, inkatho yokusakaza, inguqulo yohlelo lwe-CNC, i-ID yomsebenzisi, namalogi okulinganisa kuwo wonke amageji asetshenzisiwe
- Siqinisekisa ukuqedwa kwendawo ngawo womabili amaphrofayli kanye nokuqhathanisa okubonakalayo ngokumelene namazinga we-ASTM B487
- Senza ukuhlola isifutho sikasawoti (i-ASTM B117) ezingxenyeni eziqediwe lapho ukumelana nokugqwala kuwumgomo obalulekile.
Awekho amaqoqo emikhumbi engenawo irekhodi lokuhlola elisayiniwe—futhi alikho irekhodi elisulwayo ngaphandle uma yonke indawo yokuhlola ihambisana nemibandela yokwamukela eshiwo yikhasimende, hhayi nje imingcele yangaphakathi.
Ukwethembeka Akusona Isimangalo—Kukalwa Ngokuvumelana Kokulethwa
Ukukhiqiza ngokwezifiso okuthembekile kusho ukushaya umnqamulajuqu ngaphandle kokudela ukunemba. Sigcine >97% ukulethwa ngesikhathi kokukhiqizwa kwevolumu emaphakathi phakathi nezinyanga ezingama-27 ezedlule—hhayi ngezikhathi zokuhola, kodwa ngokushumeka izinqubo zokugeleza komsebenzi ezinciphile ekuhleleni umjikelezo wokusakaza, ukuhlela i-CNC, nokulawulwa kolayini wokwelapha ukushisa. Ama-oda e-prototype ahamba ngamaseli onjiniyela azinikele. Iqalisa ukukhiqiza izexwayiso zokugcwalisa izinto ezizenzakalelayo eziboshelwe ezikhathini zokuhola zabahlinzeki. Ayikho “imali ekhokhelwa ngokushesha” yemisebenzi ephuthumayo—izingxoxo zokuhwebelana nje ezisobala: “Singakwazi ukuletha ezinsukwini eziyi-18 uma silungisa ishejuli yokwelapha ukushisa. Noma ezinsukwini ezingama-22 ngokuguga okugcwele ngokwe-AMS ngayinye.”
Uma sibheka phambili, sinweba i-R&D ezinqubweni zokwenziwa kwe-hybrid casting-machining—ikakhulukazi ukufakwa kwe-investimenti komumo we-net-shape wezingxenye zengxube ye-nickel eyinkimbinkimbi, okulandelwa ukukhishwa kwesitoko se-CNC okunembe kakhulu. Imiphumela yangaphambi kwesikhathi ikhombisa udoti wezinto ezibonakalayo ongaphansi ngo-32% kanye nokuphuma ngokushesha okungama-20% ezingxenyeni ezifana namavalvu omfutho wezintambo eziningi. Umgomo wethu awukona nje ukuhlangabezana nemininingwane yanamuhla. Okokusiza amakhasimende akhe amasistimu akusasa anokubekezelela okuqinile, izingcindezi eziphakeme, nezikhawu zesevisi ezinde.
Uma iphrojekthi yakho elandelayo ihlanganisa izingxenye zengxube ye-nickel esekelwe ku-nickel-ikakhulukazi i-AMS 5387, T800, noma amanye amamaki e-cobalt-nickel asebenza kahle kakhulu-qala ngokuziphatha kwezinto ezibonakalayo, hhayi nje imidwebo. Khetha uzakwethu olawulo lwakhe lwenqubo lufana nokulindelekile kokusebenza kwakho. Khetha ukwethembeka okwakhelwe kuso sonke isinyathelo-akuthenjisiwe eshidini lokuthengisa.
