Lapho onjiniyela becacisa izingxenye zokusakaza ze-gravity die die of hydraulic valves, pump housings, noma i-winch system shafts, abagcini nje ngokuthenga insimbi—bavikela ukuqina kobukhulu ngaphansi kokucindezela kwebha engu-300+, ubuqotho be-microstructure ngemva kokuhamba ngebhayisikili elishisayo, kanye nokuqedwa okungaphezulu okumelana nokuguga okuguquguqukayo. Kungakho a imboni yezingxenye zokukhiqiza amandla adonsela phansi kumele wenze okungaphezu kokuthela insimbi encibilikisiwe emishinini yensimbi. Kumelwe yakhe ukubikezela konjiniyela—kuyo yonke inqwaba, wonke umjikelezo wokuphatha ukushisa, sonke iskena se-CMM.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ilethe lokho kubikezela kusukela ngo-2012 kusukela endaweni yayo eqinisekisiwe ye-ISO e-Qingdao. Sibone amakhasimende eshintsha abahlinzeki ngemva kokulandelana kwezingxenye ezintathu zephampu ye-cobalt cobalt alloy AMS 5387 ehlulekile ukuhlolwa kokuvuza—hhayi ngenxa ye-porosity, kodwa ngenxa yokulungiswa okungaguquki kokusanhlamvu eduze kwamashaneli okupholisa. Kungaleso sikhathi lapho esangena khona: sakha kabusha izindawo ezibandayo zasendaweni, saqinisekisa ukulingiswa kokuqinisa ngokumelene nama-micrograph angempela, futhi sabamba ubulukhuni bokugcina phakathi kuka-±2 HRC ezingxenyeni ezingu-42 indawo ngayinye. Umphumela? Ukwehluleka kwenkambu engu-Zero ezinyangeni eziyi-18 emihlanganweni yephampu ye-North Sea subsea.
Amandla angempela adonsela phansi amandla adonsela phansi awalinganiswa ngenani lamathani noma isikhunta—kufakazelwa ngendlela ophatha ngayo izinto ezinzima. Ama-alloys e-cobalt-nickel afana ne-T800 ne-AMS 5387 amelana nokwenza imishini, aqhekeke ngesikhathi sokucisha, futhi afune amanani anembile erempu eshisayo. Amafekthri amaningi akhipha ukwelashwa kokushisa. Asazi. Ukuhlanganiswa kwethu okuqondile kusho ukuthi ithimba elifanayo elisakaza isilinda sephampu ye-piston liphinde lihlele isithando somlilo, liqaphe ukuguqulwa kwesigaba ngedatha ye-dilatometry, futhi liqinisekise i-austenite egciniwe nge-XRD ngaphambi kokuthi kuqale ukuqhuma kwe-CNC. Awekho ama-handoffs. Ayikho i-batch drift. Iketango lenqubo elilodwa nje—kusuka ku-billet eluhlaza ukuya engxenyeni eqediwe—nokulandeleka okugcwele kwempahla kuze kufike kusitifiketi sokugaya kanye nelogi encibilikayo.
Kodwa ukulingisa kukodwa akuqinisekisi ukusebenza. Izindlu ze-gravity die cast zingaba ne-metallurgy ephelele futhi zisahluleke uma ukubekezelela kwe-GD&T kunqwabelana ngokungalungile ngesikhathi somshini wesibili. Yingakho ukubuyekezwa kwethu konjiniyela kuqala ngaphambi kokuthi kubhalwe indlela yamathuluzi yokuqala. Lapho i-OEM yaseYurophu isithumelela umdwebo werola ye-shaft emaphakathi engajwayelekile ene-±0.005 mm cylindricity ku-210 mm OD, sihlabe umkhosi imfuneko yokuphazamiseka kokulingana ngokumelene nobuhwaqane bobuso obusakazwayo. Esikhundleni sokucaphuna ngokungaboni, siphakamise indlela exubile: i-gravity die cast ku-GGG-40, edambisa ingcindezi, bese kuba umhlabathi onembayo nge-in-process laser micrometry. Ukulethwa kuhlale emavikini angu-6. Izindleko zehle ngo-22% uma kuqhathaniswa ne-CNC egcwele esitokweni sebha. Futhi ingxenye iphumelele ukuhlolwa kokusebenza kwempilo emijikelezweni eyizigidi eziyi-1.8—27% ngaphezu kokucaciswa.
Sisebenzela amakhasimende azi umehluko phakathi “kokuthobela ubukhulu” kanye “nokwethenjelwa ngokusebenza.” Babuza mayelana namajika esinxephezelo sokuncipha kwe-iron—hhayi nje ama-callouts okubekezela. Bacela imibiko yokuhlaziywa kwe-spectral ehambisana nokuthunyelwe kwe-PPAP. Badinga imibhobho ye-cobalt alloy esinda ku-450°C ukushaqeka okushisayo ngaphandle kwe-microcracking—futhi bazohlola amasampula amahlanu ngaphambi kokugunyaza inkatho. Lokho kuyiqiniso ngemuva kwawo wonke ama-oda athunyelwa ezinkampanini zensiza kawoyela eTexas, izihlanganisi zesistimu ye-hydraulic eJalimane, nabakhi bemishini yasolwandle eSingapore. Amandla ethu awasiwo isikali. Kugxilwe kuyo: ezingxenyeni zezimboni ezine-alloy ephezulu lapho ukwehluleka kungeyona inketho. Ezinqubweni lapho ukuchezuka okungu-0.3°C kumazinga okushisa angaphambi kokushisa kushintsha isikhala sengalo ye-dendrite—futhi ekugcineni, nempilo yokukhathala. Ngokubambisana lapho onjiniyela bekhuluma ngokuqondile nama-Foundry metallurgists, hhayi ngezingqimba zokuthenga.
Uma iphrojekthi yakho elandelayo ihlanganisa amavalvu okucindezela amasistimu okugeza anengcindezi ephezulu, izindlu zamasilinda zamaphampu ashintshashintshayo, noma amarola e-winch shaft ngokwezifiso zezimoto zezimayini—buza ukuthi ingabe umphakeli wakho ulawula lonke uchungechunge: ukuqinisekiswa kwezinto ezibonakalayo, ukuqinisekiswa kwedizayini yokufa, ukumodeliswa kokuqina, ukuprofetha kokwelashwa kokushisa, kanye nokuqeda ama-axis amaningi ngesikhathi sokuhlola. Ngoba ezingxenyeni zensimbi ezibaluleke kakhulu kumishini, umkhawulo wephutha uhlala ezikhaleni phakathi kweminyango. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., azikho izikhala. Ifekthri eyodwa nje yezingxenye zokusakaza ze-diese—eyakhelwe ukunemba, ihlolwe ngokwenza, futhi ithenjwa lapho ukusebenza kungaxoxiswana khona.
