Xa iinjineli ze-aerospace zidinga ii-turbine blades, ii-nozzles ze-fuel, okanye i-actuator housings ezibamba ukunyamezela kwe-± 0.02 mm phantsi kwe-thermal 800 ° C kunye ne-15,000 yemithwalo ye-hydraulic ye-psi-ayizinzeli "ilungile ngokwaneleyo" yokuphosa. Baya kwi Umzi-mveliso wokuphosa utyalo-mali kwi-aerospace ngoqeqesho oluqinisekisiweyo lwe-metallurgical, hayi nje isakhono sokwenza umngundo.
Yiyo loo nto amaqela oyilo eMntla Melika naseYurophu ehlala ethumela imizobo ye-GD&T-ecebileyo yeenxalenye zempompo ye-cobalt-nickel ngqo kwi-Qingdao Qiangsenyuan Technology Co., Ltd.-hayi ngenxa yokuba yeyona ndlela iphantsi, kodwa ngenxa yokuba ikhonkco lenkqubo yalo lisusa ezona ndawo zixhaphakileyo zokungaphumeleli: i-micro-shrinkage kumacandelo abhityileyo, ulwahlulo lwe-carbide, ukucalulwa kwe-carbide, ukucalulwa kwe-carbide, ukucalucalulwa kwe-carbide, ukucalulwa kwe-carbide, ukucalulwa kwe-53m 8m kwi-heat ye-MS kunye nokwahlukaniswa kunye noomatshini bokugqibela.
Akukho zixhobo zimbini zokusasa emoyeni ezisebenza ngendlela efanayo—ngoko ke nomzi-mveliso awufanele ube nawo
Siye sabona iiprojekthi ezininzi zilibazisekile ngenxa yolindelo olungahambelaniyo: umthengisi ucaphula "ukutyalwa kotyalo-mali" ngelixa eqhuba izixhobo zesanti-cast; enye isiqinisekiso "i-AMS 5387 iyahambelana" ngaphandle kweengxelo ze-spectrographic zebhetshi; owesithathu ubambe idatha ye-CMM kuphela yokuhlola inqaku lokuqala-hayi yonke into eninzi. E-Qingdao Qiangsenyuan, impendulo iqala ngokulandeleka kwezinto-kungekhona amabango okuthengisa.
Yonke i-T800 i-cobalt-based alloy ingot ifika neengxelo zovavanyo lokusila, uhlaziyo olupheleleyo lweekhemikhali kwindawo, kunye neelog zembali ye-thermal ebotshelelwe kubushushu bomntu ngamnye. Oko kuthetha ukuba xa umthengi e-odola i-42 cobalt alloy nozzles kwi-high-pressure fuel metering system, i-Foundry ayigaleli nje isinyithi-ibonisa ukuqhelaniswa kwengqolowa ngokuchasene nomkhombandlela wokuhamba kwindibano yepateni ye-wax, ilungelelanisa ubushushu be-preheat nganye ubukhulu becandelo, kwaye ibambe ixesha lokuqiniswa ngaphakathi kwe-± 90 imizuzwana yemveliso yokulinganisa.
Oku akuyothiyori. Kwenye iprojekthi yamva nje ye-OEM ye-hydraulic actuator yaseYurophu, sibambe i-0.035 mm ukutenxa kodonga olungqingqwa kwi-wax master *phambi* kokudipha kweqokobhe le-ceramic — kusetyenziswa ukuskena kwecontour ye-optical endaweni ye-calipers yezandla. Oko kusindise iiveki ezintathu zokuphinda kusetyenzwe kwaye kwasusa inkunkuma kwimidlalo eyi-17 yokuqala.
Ukudityaniswa ngokuthe nkqo akusiyo i-buzzword-kuphela kwendlela yokulawula ingqibelelo ye-microstructure
Ababoneleli abaninzi bakhupha ukugqiba, unyango lobushushu, okanye ukwenziwa komatshini wokugqibela. Oko kwaphula uxanduva-kwaye yazisa iinguqu ezingalawulwayo. Umsebenzisi wesithando sokushisa kwindawo enye unokuhamba nge-5 ° C / min; enye kwi-12 ° C / min. Bobabini badibana ne-"AMS 2750E Class 2" ephepheni-kodwa inye kuphela ihambisa i-precipitate dispersion kwi-cobalt-nickel alloys.
I-Qingdao Qiangsenyuan iqhuba onke amanyathelo abalulekileyo phantsi kophahla olulodwa oluthobelayo lwe-ISO: ukuphosa utyalo-mali, i-multi-axis CNC machining (kubandakanywa ne-5-axis contouring ngaxeshanye), unyango lobushushu, kunye nokugqitywa komphezulu njenge-electropolishing okanye i-HVOF yokwambathisa. Akukho handoffs. Akukho zithuba zedatha. Hayi "uthe/utshilo" ngexesha lohlalutyo lwengcambu.
Waba yintoni umphumo? Izindlu ze-piston pump cylinder ezidlula i-100% yovavanyo loxinzelelo kwi-1.5 × ingcinezelo yokusebenza-kunye nokuvuza kwe-zero kwiiyunithi ze-212 kwi-middle-volume run yamva nje. Ngoba? Ngenxa yokuba iqela elifanayo eliqinisekise uyilo lokungena liphinde laqinisekisa uburhabaxa bomphezulu bokugqibela be-ID (Ra ≤ 0.4 µm) kunye nokusabalalisa ubulukhuni obuqinisekisiweyo (HRC 42-46) kubo bonke ubude bebhore-kungekhona nje kwiisampuli ezintathu zesampulu.
Akunjalo malunga nokuphosa amacandelo-imalunga nokusebenza ngokufanelekileyo
Ezinye iifektri zotyalo-mali kwi-aerospace ziphatha i-GD&T njengohombiso. I-Qingdao Qiangsenyuan iyithatha njengesivumelwano. Xa umzobo ubiza ukunyamezela kwesikhundla se-Ø0.05 mm kwimingxuma emithandathu ye-bolt ehambelana ne-datum plane eyenziwe emva kokuphosa, umgangatho wevenkile usebenzisa umatshini wokulinganisa ulungelelaniso kunye nesisombululo se-0.001 mm-kwaye urekhoda yonke into efundwayo kwi-database ekhuselekileyo edibaniswe nenombolo yobushushu benxalenye.
Elo nqanaba lokuqina libaluleke kakhulu apho ijometri idibana nomsebenzi: iirola zeshaft yeziko lewinch yezithuthi zobunjineli kufuneka zijikeleze ngokwenyani ngaphakathi kwe-0.01 mm iyonke yesalathisi sokufunda (TIR) phantsi komthwalo oguqukayo. Iivalvu zoxinzelelo zifuna indawo yokutywina engavuziyo kunye nokugqiba komphezulu okuhambelana neprofayili yoxinzelelo lwe-elastomer. Ezi ayizo "izinto ezintle zokufumana." Ziyaphumelela / ziyasilela iindlela ezifakwe kuyo yonke iprotocol yokuhlola.
Abathengi basixelela ukuba oku kwenza uphononongo lobunjineli lukhawuleze — hayi kancinci. Omnye umenzi wempompo waseMntla waseMelika unqumle umjikelo wokuphinda uyilo ukusuka kwiintsuku ezili-11 ukuya kwiintsuku ezi-3.5 emva kokutshintshela kwingxelo yokwenziwa kwe-Qingdao Qiangsenyuan kwangethuba: utoliko lwexesha lokwenyani lwe-GD&T, ukunyamezelwa kwemodeli yokupakisha, kunye neengcebiso zemathiriyeli ezizezinye ezisekwe kwiindlela zokwenyani zokuphendula ubushushu bangaphakathi-hayi idatadata yegeneric.
Ukujonga phambili: iinkqubo ze-hybrid, kungekhona nje ukuphosa
Umda olandelayo awukho iziko zikhulu okanye iiCMM ezikhawulezayo. Kuqina ukudityaniswa phakathi kokusakha kunye nomatshini-ingakumbi kwiijiyometri zangaphakathi ezintsonkothileyo ezingenakwenzeka ukuba ziphunyezwe ngayo nayiphi na inkqubo yodwa. Ngoku siphuhlisa ukuhamba komsebenzi oxutyiweyo apho utyalo-mali olukufutshane ne-net yeemilo luhamba ngokuchaneka kwe-EDM yokomba *ngaphambi* kokugqibela kwe-CNC yokusila-ivumela iitshaneli zokupholisa ngaphakathi kwezindlu ze-turbine ezine-0.3 mm ubukhulu bodonga kunye ne-12: i-12: i-aspect ratios.
Oko kufuna intsebenziswano enzulu ye-R&D-hayi nje kubathengi, kodwa kunye namaqabane ezenzululwazi. Okwangoku, umsebenzi wethu wophuhliso odibeneyo ugxile ekuphuculeni iindlela zokuqinisa ukwahluka kwe-T800 yenqanaba elisezantsi le-sigma, ukunciphisa ixesha lokumisa isisombululo se-post-cast ngama-37% ngaphandle kokubeka esichengeni ukuxhathisa.
Ukuba icandelo lakho elilandelayo le-aerospace lifuna ngaphezulu kokuchaneka komgangatho-ukuba lifuna indlela yokuziphatha enokuxelwa kwangaphambili, ukulandeleka okugcweleyo, kunye nokunyamezela i-zero kwinkqubo yokukhukuliseka-udinga Umzi-mveliso wokuphosa utyalo-mali kwi-aerospace yakhelwe ukuphumeza okubalulekileyo. Hayi umthamo. Hayi isantya. Ukuqiniseka.
