Xa iinjineli zichaza a metal investment casting factory kwi-mission-critical valves hydraulic valves okanye i-high-wear-wear pump housings, ayithengi nje iindawo-zikhusela uzinzo lwe-dimensional phantsi kwe-300 yoxinzelelo lwe-bar, ukunyaniseka kwe-microstructure emva kokuhamba ngebhayisikili yokushisa, kunye nokunyamezela kwe-porosity kwi-cobalt-nickel alloy nozzles. Kulapho amava okwenene ehlabathi ahlula abathengisi kumaqabane.
Kutheni uTyalo-mali Lufuna Ngakumbi Kunobumba nje kunye neWax
Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba le-prototype-kungekhona ngenxa yoyilo olubi, kodwa ngenxa yokukhethwa metal investment casting factory iswele ulawulo lwe-metallurgical phezu kwe-AMS 5387 cobalt alloy okanye ayikwazanga ukubamba ± 0.015 mm GD & T kwizindlu ze-cylinder cylinder. Ukwenziwa kotyalo-mali “ayisiyonto nje enye inkqubo.” Yeyona ndlela isebenzayo yeejiyometri ezintsonkothileyo ezinje ngempompo yepiston eneendlela zokupholisa zangaphakathi-kwaye iyasilela ngokuthula xa umkhondo wemathiriyeli ekrwada ityibilika, xa iqokobhe libhaka imijikelo likhukuliseka, okanye xa ubushushu bobushushu budlula nge-8°C.
Ukuchaneka kokwenyani kuqala ngaphambi kwepateni yokuqala ye-wax: i-ingots ye-T800 ye-alloy eqinisekisiweyo, uphicotho olubhaliweyo lwababoneleli, uhlalutyo lwe-spectral kuwo wonke ubushushu. Emva koko kuza ukuguquguquka kweqokobhe le-ceramic-ukufuma okulawulwayo, amaxesha okudipha alungelelanisiweyo, ukuqinisekiswa okupheleleyo kokutshiswa. Siqinisekisa ibhetshi nganye ngovavanyo lwe-tensile, i-metallografi, kunye ne-X-ray ye-radiography-hayi nje i-gross voids, kodwa i-microporosity clusters kufuphi neefilts ezigxininiswe kuxinzelelo. Yileyo ndlela uphepha ngayo ukungaphumeleli kwintsimi kwi-oilfield downhole izixhobo ezisebenza kwi-150 ° C kunye ne-10,000 psi.
Ukudityaniswa okuthe nkqo akulolizwi le-Buzzword-Luhlahlo-lwabiwo mali lwakho lokunyamezela
Abanye ababoneleli benza oomatshini bangaphandle. Abanye balima ngaphandle konyango lobushushu. Oko kuqhekeka kubulala ukuphinda-phinda kwe-dimensional. I-cast cast house iyancipha ngokungalindelekanga ukuba ukukhululeka koxinzelelo lwenzeka kwi-620 ° C endaweni ye-640 ° C-okanye ukuba ukulungiswa kwe-CNC akubandakanyi ukuchithwa kwe-residual casting. Kwiziko lethu eliseQingdao, elinye iqela lobunjineli liphethe ikhonkco elipheleleyo: utyalo-mali → ukuvala isisombululo → i-multi-axis milling → i-HVOF yokwambathisa → uhlolo lokugqibela oluqinisekisiweyo lweCMM.
Oku akuyothiyori. Xa i-OEM yempompo yaseYurophu yayidinga iipleyiti zesiseko sentsimbi engama-42 kunye no-0.02 mm flatness ngapha kwe-1.2 m² umphezulu, senze imaphu yephepha lokulwa ukusuka ekujuleni ukuya kumatshini sisebenzisa i-3D yokwaleka kokuskena. Silungelelanise ulandelelwano lwe-clamping, songeza i-intermediate-relief ephakathi, kwaye saqinisekisa i-coefficients yokwandiswa kwe-thermal kwindawo yobushushu nganye. Isiphumo? Ukwamkelwa kwe-100% yokuqala-akukho kuphinda kusebenze, akukho nkunkuma. Elo nqanaba lolawulo likhona kuphela apho iinjineli ezisakhayo zithetha mihla le nabaprogram be-CNC kunye nee-metrologists-hayi nge-imeyile ephathwayo.
Imingeni ye-alloy ye-Real-World ifuna iimpendulo ze-Real-World
I-cobalt-nickel alloys ayihambi njenge-316 engenasici. Basebenza nzima, baqhuba ubushushu ngokungalunganga, kwaye batshabalalisa izixhobo ze-carbide 3 × ngokukhawuleza. Ukuba eyakho metal investment casting factory khange isebenze iiplagi ze-AMS 5387 iinyanga ezintandathu ngokuthe tye, idatha yazo yobomi besixhobo iphelelwe lixesha. Silandelela zonke iipatheni zokunxiba, izinga lokupholisa, kunye nesignesha ye-spindle vibration-hayi yeengxelo, kodwa ukuqikelela ukusilela kwesixhobo phakathi kwemizuzu emi-3.
Ivenkile yethu ineeseli ezinikezelweyo ze-superalloys: i-cryogenic-cooled spindles, i-hydraulic fixtures, kunye nenkqubo yokuhlola ukuba ihlawula ngokuzenzekelayo ukukhula kwe-thermal ngexesha lomjikelo omde wokusila. Kwi-T800-based non-standard centre shaft rollers esetyenziswa kwiinkqubo zewinch ekude nonxweme, sidibanisa utyalo-mali kunye nokuguqula ukugqiba kwiijenali zomhlaba owenziwe lukhuni-ukuphumeza iRa 0.4 µm umphezulu womphezulu ngelixa ugcina ubulukhuni obungundoqo be-HRC 42–46. Akukho plating. Akukho kutsha kokusila. Ukuqhubekeka nje kwe-metallurgical ukusuka kwesikhumba ukuya kumbindi.
Ukuthembeka kokuhanjiswa kuqala ngento oyibonayo-kunye nento ongayiboniyo
Abathengi bayabuza: "Ngaba ungabetha ukuhanjiswa kwe-Q3?" Impendulo enyanisekileyo ixhomekeke kwizinto ezintathu abangafane bazihlole: ixesha lokuhamba kwezinto eziluhlaza (i-cobalt alloys zihlala zifuna iiveki ze-12 +), i-NDT backlog (i-radiography slots incwadi ye-3 iiveki ngaphandle), kunye nobunzulu bokuqinisekiswa kwe-GD & T (ngaba umthengisi wakho uqinisekisa ukunyamezela isikhundla kunye nabathelekisi be-optical-okanye ukubiza nje 'Kulungile' emva kwe-CMM?).
Sipapasha iideshibhodi zexesha lokwenyani ngaphakathi-hayi njenge-fluff yentengiso, kodwa njengengqeqesho yokusebenza. Yonke iodolo ifumana ukuphononongwa kwesango elisebenzayo: ukuphosa ubunjineli kuqinisekisa imida yengqibelelo yeqokobhe; izicwangciso zoomatshini ziquka ezinye iindlela zesixhobo ukuba ufakelo oluthile luyaphela; I-QA ibambe ukukhutshwa kokugqibela de uvavanyo olusebenzayo luhambelana neegophe zokubola koxinzelelo oluchaziweyo. Yiyo loo nto i-92% yee-odolo zethu zomthamo ophakathi zithumela ngenqanawa phakathi kweentsuku ezi-±2 zokuzibophelela-kwanangexesha lexesha eliphakamileyo.
Ukuba ufuna i metal investment casting factory ephatha indlu yempompo yakho njengemveliso yayo-hayi inxalenye yempahla-qala ngokulandelelwa kwezinto, imfuno yokuhlola i-GD & T-protocol yokuqala, kwaye uqinisekise ukudibanisa ngokuthe nkqo ngaphaya kwencwadana. Ukuchaneka akwenziwa. Yenziwe ngobunjineli, ilinganisiwe, kwaye iqinisekisiwe-indawo yobushushu enye, into enye, i-micrometer enye ngexesha.
