Xa iinjineli ze-aerospace zidinga ii-turbine blades ezibamba i-± 0.05 mm tolerances kwi-1,200 ° C-okanye izindlu ze-nozzle ze-fuel ezisinda kwiinkonzo zeeyure ezingama-30,000 zihlala ngaphandle kokusasazwa kwe-microcrack-aziqali nge-generic foundry quote. Baqala ngokuziphatha okubonakalayo, imbali ye-thermal, kunye nozinzo lwe-dimensional kuyo yonke imijikelo yonyango lobushushu. Yiyo loo nto Utyalo-mali lokuphosa umzi-mveliso we-aerospace Intsebenziswano ayifane iphumelele kwiinkcukacha zekhathalogu yodwa. Baxhomekeke kuqeqesho lwe-metallurgical, inkqubo ecacileyo, kunye namava okusebenza kunye ne-alloys efana ne-AMS 5387 cobalt-chromium kunye ne-T800-grade superalloys-izinto ezichasene nomatshini kodwa zifuna ukuchaneka kwe-net-shape.
Sibone iiprojekthi ezininzi ziphazamiseka kwisiqinisekiso ngenxa yokuba indlu yokuphosa ithathe izinto ze-aerospace "njengomnye nje umsebenzi onyamezelayo." Umxhasi omnye we-AMS 5387 yempompo yendlu ayiphumelelanga kuvavanyo lokungcangcazela-hayi kwiziphene zoyilo, kodwa ukusuka kwisakhiwo esingahambelaniyo senkozo kuzo zonke iibhetshi. Oyena nobangela? Umthengisi ofumene ingots ze-cobalt-nickel ekrwada ngaphandle kwesatifikethi somgangatho webhetshi, emva koko watsiba isisombululo sokuqinisekisa. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke i-aerospace casting njengenkqubo ye-thermomechanical-kungekhona nje imilo yesinyithi. Indawo yethu ehambelana ne-ISO eQingdao iqhuba utyalo-mali olupheleleyo: indibano yepateni yewax, isakhiwo seqokobhe le-ceramic, i-dewaxing, ukudubula okulawulwa yi-vacuum, ukugalela ngokuchanekileyo phantsi kwe-argon, kunye nonyango lobushushu emva kokuphoswa ngokugawulwa kwe-thermocouple ngexesha langempela. Akukho nyathelo linikezelwa ngaphandle. Akukho nxalenye yezinto eziphathekayo ezilahlekelwa kukulandeleka.
Yintoni eyahlula umsebenzi wokuphosa utyalo-mali olune-aerospace-i-aerospace-i-aerospace-i-aerospace-injongo eqhelekileyo ayisosixhobo kuphela-yindlela yokuphosa ngokuqinileyo edibanisa neenkqubo ezisezantsi. Sisebenza ngomatshini i-72% ye-aerospace castings yethu endlwini kusetyenziswa amaziko e-CNC e-5-axis alinganiswe imihla ngemihla ukuya kwi-ISO 10360-2. Kutheni ibalulekile nje loo nto? Ngenxa yokuba umzimba wevalve ye-cobalt ingxubevange ephoswe ukuya ku-±0.3 mm ayikwazi ukufikelela kwi-±0.025 mm yonyamezelo lwe-ID yokugqibela ngaphandle kokuba isilungiso somatshini sibhekisa kumphezulu ofanayo wedatum esekiweyo ngexesha lokudityaniswa kokungunda kweqokobhe. Iinjineli zethu ziyila ngokudibeneyo amasango okujula kunye nezinyusi *nolandelelwano lokugqibela lomatshini engqondweni-kungekhona emva kwenyani. Umzekelo, xa sivelisa izindlu zesilinda sempompo yepiston kwiinkqubo zokusebenzisa i-hydraulic actuation, sibeka abondli ukuze banciphise uxinzelelo olushiyekileyo kwiindonga zebhore, emva koko umatshini wangaphakathi osebenzisa izixhobo ze-carbide ezihambelana neprofayili yobulukhuni bomhlaba. Oko kudityaniswa kunciphisa i-41% kulwakhiwo lwenqaku lokuqala xa kuthelekiswa neevenkile apho ukuphosa kunye noomatshini basebenza njengamasebe afakwe i-siled.
Abanye banokuxoxa ukuba ukujulwa kwesanti kunika uguquko olukhawulezayo lwezakhiwo ezinkulu ze-aerospace. Kodwa kwiijiyometri ezinodonga olucekethekileyo, ezintsonkothileyo-ezinje ngamacandelo e-turbine shroud okanye iilayini zegumbi lokutsha-utyalo-mali luhlala lungenakuthathelwa indawo. Iimbumba zesanti zilwa nobunzima bodonga phantsi kwe-4 mm; iigobolondo ze-ceramic zibamba i-1.8 mm ngokuqhubekayo. Okubaluleke ngakumbi, ukuphosa isanti kwazisa imingcipheko ye-silica ebeka esichengeni ubomi bokudinwa kumacandelo ajikelezayo. Siqinisekisa yonke ibhetshi yeqokobhe le-aerospace nge-X-ray tomography-hayi nje i-radiography-kwaye siyala nawuphi na umngxuma odlula i-ASTM E192-22 Level 2 porosity. Kunyaka ophelileyo, abathengi ababini batshintsha kubathengisi baseYurophu emva kokufumana iifilimu eziphindaphindiweyo ze-subsurface oxide kwimibhobho ye-cobalt alloy. Inkqubo yethu isebenzisa i-vacuum degassing pre-pour kunye namazinga okupholisa alawulwayo angaphantsi kwe-100 ° C / iyure nge-gamma-prime solvus-ukuphelisa ezo filimu ngokupheleleyo.
Abathengi be-aerospace abafuni nje iinxalenye. Bafuna ubungqina obulungele uphicotho-zincwadi: ii-certs eziphathekayo ezinohlalutyo olupheleleyo lobushushu bekhemikhali, iingxelo zeCMM ezibotshelelwe kwii-callouts ze-GD & T kwi-ASME Y14.5 imizobo, iinkuni zonyango lobushushu zigxininiswe nge-metallurgists eziqinisekisiweyo, kunye neerekhodi zovavanyo ezingonakalisi ezilandelelwa kwi-NADCAP AC7108 Rev. ubume bokuhlola, ukukhuphela iingxelo eziqinisekisiweyo, kunye nokulandelela ukutenxa komgangatho ngokuchasene neetshathi zolawulo lwe-SPC. Ukwakhiwa kweprototype engxamisekileyo, sicinezela umjikelo ukusuka ekukhutshweni komzobo ukuya kukuhanjiswa kwenqaku lokuqala ukuya kwiintsuku ze-14 zokusebenza-ngaphandle kokutsiba ixesha lokumisa iqokobhe okanye ukunciphisa ukubamba kwesisombululo. Eso santya sivela kuyilo lokuhamba komsebenzi obhityileyo, hayi amanyathelo enkqubo echaphazelekileyo.
Ukuba icandelo lakho elilandelayo le-aerospace lifuna i-AMS 5387 cobalt alloy, i-T800-based geometry, okanye i-pressure-rated stainless steel castings enemigangatho esebenzayo efuna i-Ra ≤0.4 µm-siyazakhela ukuba zenze, kungekhona nje ukudlula. Akunjalo njengezinto ezingaphandle kweshelufu, kodwa njengeenkqubo zobunjineli ezenziwe kwiinkqubo eziphindaphindwayo, ezibhaliweyo, kunye neenkqubo zokuphendula ngesinyithi. Ndwendwela https://www.tsingtaocnc.com ukuphonononga amandla obuchule, ucele iingxelo zovavanyo lwemathiriyeli, okanye ucwangcise uphononongo lobunjineli kunye neqela lethu lokudibanisa umatshini. Ukuchaneka kwi-aerospace iqala ixesha elide ngaphambi kokugalela-kwaye iphela kuphela xa yonke imilinganiselo, i-microstructure, kunye nomsebenzi ongaphezulu udibana nenjongo ebalulekileyo yokubhabha.
