Xa iinjineli zicacisa iinxalenye zeempompo ze-hydraulic, iivalvu ze-oilfield, okanye ii-winch-duty-winch systems, azifuni nje isinyithi-zifuna ukuqinisekiswa kwe-dimensional. Ukuphambuka kwe-0.02 mm kwisihlalo somlomo we-cobalt-alloy kunokubangela i-cavitation. Ukulungelelaniswa kakuhle kwe-0.05 mm kwindlu yesilinda yepompo yepiston kunokukhawulezisa ukuguga ngama-40%. Yiyo loo nto ii-OEM ezikhokelayo kunye nababoneleli beTier-1 bebuyela rhoqo kwi- ilahleko yewax echanekileyo kwifektri yokuphosa olujonga unyamezelo kungekhona njengento ekujoliswe kuyo—kodwa njengesiseko.
Kutheni uTyalo-mali lokuCasa kusaphumelela apho i-CNC yodwa isilela khona
Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype kuba abayili becinga ukuba ukwenziwa kwe-multi-axis kunokuphatha iijiyometri ezintsonkothileyo zangaphakathi-ezifana neepaseji eziqukuqelayo ngaphakathi kwezindlu zempompo ze-AMS 5387 okanye iitshaneli zokupholisa eziphantsi kwe-T800 yevalve yealloyi. I-CNC isebenza kakuhle kwiimpawu zangaphandle. Kodwa xa ubukhulu bodonga busihla ngaphantsi kwe-2.5 mm, i-radii yangaphakathi iyancipha ukuya kwi-R0.3, kunye nengqibelelo ye-metallurgical kufuneka iphile kwi-350 ° C kwibhayisekile eshushu? Kulapho ukulahlwa kwewax elahlekileyo kuzisa into yokusila engakwaziyo: ukuntsonkotha kobume obunetha ngaphandle kokubeka esichengeni ubume benkozo.
Kwiziko lethu eQingdao, yonke icandelo le-cobalt-nickel liqala ngepatheni ye-wax eyakhiwe ukusuka kwidatha ye-CAD eqinisekisiweyo-kungekhona iifayile ze-STL eziqikelelwayo. Sisebenzisa i-vacuum-assisted ceramic shell dipping, i-dewaxing elawulwayo kwi-120 ° C, kunye ne-furnace preheating ukuya kwi-1,050 ° C ngaphambi kokugalela. Oku kuphelisa i-micro-shrinkage voids eqhelekileyo kwezinye iindlela zokuphosa isanti. Isiphumo? Ukugqityezelwa komphezulu we-As-cast of Ra 3.2 µm, ukunyamezela komda we-±0.05 mm ukuya kuma-200 mm, kunye nokuthotyelwa ngokupheleleyo kwe-ISO 8062-2:2013 yokunyamezela inxalenye.
Ukudityaniswa okuthe nkqo ayisiyonto iBuzzword-Yi-inshurensi yakho yoMda
Ezinye ii-Foundries zithumela ii-castings kwiivenkile zomntu wesithathu ukuze zenziwe ngoomatshini. Oko kwazisa izinto ezintathu eziguquguqukayo ezingalawulekiyo: ukugqwethwa kwe-thermal ngexesha lothutho, ireferensi yedatha engahambelaniyo, kunye nokulibaziseka kwe-loops yengxelo xa i-callouts ye-GD&T ingqubana nejometri ye-as-cast. Siphepha zonke zontathu ngokuphatha ukuphosa, ukunyanga ukushisa, kunye nokugqiba phantsi kophahla olunye-naphantsi kwenkqubo enye yekhwalithi.
Iiseli zethu ze-CNC zisebenza ngaxeshanye i-5-axis milling kunye nenkqubo yokuqinisekisa i-CMM kuwo wonke umzimba wevalve yoxinzelelo. Xa umthengi ehambisa umzobo ngokunyamezela kokwenyani kwe-Ø0.03 mm kwimingxuma emithandathu yebholiti enxulumene nedatum esekwe kwi-flange enodonga olucekethekileyo-sisebenza ngomatshini, silinganisa, silungelelanisa, kwaye siphinda silinganise-konke ngaphakathi kweshifti enye. Akukho handoffs. Akukho kwahlulwa kwebhetshi. Akukho zithuba zokulandeleka. Iqashiso ngalinye liphethe iicerti zemathiriyeli ezigcweleyo, iilogi zokuphatha ubushushu, kunye neengxelo ezilungelelanisiweyo ezigcinwe iminyaka eli-10.
Oku kudityaniswa kubaluleke kakhulu nge-superalloys. T800 cobalt-based izinto lukhuni ngokungalindelekanga emva annealing isisombululo. Ukuba umatshini wenzeka ngaphambi kokuguga kokugqibela, uxinzelelo olushiyekileyo lusasaza kwaye lujike imiphezulu yokutywina. Inkqubo yethu itshixa ngolandelelwano: phosa → ukukhulula uxinzelelo → umatshini → ubudala → uhlolo lokugqibela. Siye sanciphisa i-post-heat-treat rework kumacandelo e-AMS 5387 ukusuka kwi-11% ukuya kwi-0.8% kwiinyanga ezidlulileyo ze-24-kuba silawula lonke ikhonkco.
Umsebenzi wokwenyani weHlabathi uQala ngoLuleko lweMathiriyeli yokwenyani
"Impahla ekrwada eqinisekisiweyo" ithetha encinci ukuba ingxelo yovavanyo lokusila ayihambelani nethegi ye-ingot-okanye ukuba ulwahlulo lwe-alloy alubonakali kwi-50 mm yokuqala yokugalela. Sifumana iialloyi ze-cobalt-nickel ngokukodwa kwii-mill eziqinisekisiweyo kwi-ASTM B575 kunye ne-AMS 5387 Rev. Iqashiso ngalinye lokuphosa lifumana uqinisekiso lwe-PMI *phambi* kokwakhiwa kweqokobhe-kwaye kwakhona emva komatshini.
Sikwagcina intsebenziswano yobuchwephesha kunye nabanikezeli be-cobalt ababini abaphambili-enye eYurophu, enye eNyakatho Melika-ukubambisana nokuphuhlisa iiparitha zokulungisa ukushisa. Umzekelo: xa siphosa imilomo ye-T800 kwiimpompo zoxinzelelo oluphezulu eziqhekezayo, sihlengahlengisa izinga lokuqina kunye nexesha lokupholisa lokungunda ngokusekwe kumxholo wekhabhoni kunye nesilicon yobo bushushu-hayi i-generic specs. Yiloo ndlela esifumana ngayo ubunzima obungaguqukiyo be-42-45 HRC kuwo wonke ama-98% emveliso eqhutywayo, hayi nje iisampuli zaselebhu.
Abathengi basoloko bebuza: “Ungakwazi ukubamba ±0.025 mm kwi-120 mm yedayamitha kwi-T800?” Ewe-ukuba umzobo ubandakanya iskimu sedatha esebenzayo, ichaza iimfuno zemfezeko yomphezulu (kungekhona nje uburhabaxa), kwaye isivumela ukuba siqinisekise ukulinganisa kwendlela yesixhobo ngokuchasene nezibonelelo zesitokhwe. Siza kukuxelela kwangaphambili ukuba kunokwenzeka. Okanye apho ukulungisa.
Ukukhetha i-Wax elahlekileyo yeFactory yokuCasa ngokuchanekileyo kuthetha Ukukhetha iProfayile yakho yoMngcipheko
Abathengisi bexabiso eliphantsi bakhuphisana ngexabiso ngekhilogram nganye. Yinyani ilahleko yewax echanekileyo kwifektri yokuphosa ukhuphisana ngokuphepha ukusilela. Yonke iplagi ye-cobalt alloy esiyihambisayo ithwala ukulandeleka okupheleleyo-ukusuka kwinani lobushushu ukuya kwidatha yokugqibela yovavanyo olusebenzayo. Zonke iinqanawa ze-winch yemoto yobunjineli zineengxelo ezinobungakanani ezisayinwe ngabahloli bethu abaqinisekisiweyo be-ASQ. Yonke iodolo ibandakanya impendulo esebenzayo yokwenziwa-hayi nje "singayenza," kodwa "nantsi indlela yokunciphisa iindleko nge-22% ngaphandle kokuncama uxinzelelo olukhulu."
Olo qeqesho kungoko izinga lokuphinda-odolwa kwethu lidlula i-76% kuwo wonke uMntla Merika, eYurophu, nakuMzantsi-mpuma Asia. Akunjalo ngenxa yokuba singabancinci. Kuba xa udibaniso lwakho lwempompo luqhuba kwi-4,000 psi kwiiyure ze-18,000, akukho nto "ilungile ngokwaneleyo." Kukho kuphela ukusebenza okuqinisekisiweyo-kunye nefektri emele emva kwayo.
