Thaum cov engineers aerospace xav tau turbine blades, roj nozzles, los yog actuator vaj tse uas tuav ± 0.02 mm kam rau ua nyob rau hauv 800 ° C thermal cycling thiab 15,000 psi hydraulic loads - lawv tsis khom rau "zoo txaus" casting. Lawv mus rau ib qho aerospace peev casting Hoobkas nrog pov thawj metallurgical kev qhuab qhia, tsis yog tsuas yog pwm-ua muaj peev xwm.
Tias yog vim li cas pawg tsim qauv hauv North America thiab Europe niaj hnub xa GD&T-nplua nuj kos duab rau cobalt-nickel twj tso kua mis ncaj qha mus rau Qingdao Qiangsenyuan Technology Co., Ltd. kho thiab kawg machining.
Tsis muaj ob lub aerospace castings coj zoo ib yam - yog li tsis muaj lub Hoobkas
Peb tau pom ntau txoj haujlwm qeeb los ntawm qhov kev cia siab tsis sib haum: tus neeg muag khoom hais txog "kev nqis peev casting" thaum khiav cov cuab yeej xuab zeb; Lwm daim ntawv pov thawj "AMS 5387 raws" yam tsis muaj cov ntaub ntawv qhia tshwj xeeb spectrographic; ib tug thib peb tuav CMM cov ntaub ntawv tsuas yog rau thawj tsab xov xwm tshuaj xyuas - tsis yog txhua txhua. Ntawm Qingdao Qiangsenyuan, cov lus teb pib nrog cov ntaub ntawv traceability - tsis yog kev lag luam thov.
Txhua T800 cobalt-raws li alloy ingot tuaj txog nrog zeb xeem ntawv qhia, tag nrho cov tshuaj reanalysis on-site, thiab thermal keeb kwm log khi rau ib tug neeg heats. Qhov ntawd txhais tau hais tias thaum tus neeg siv khoom xaj 42 cobalt alloy nozzles rau lub siab-siab roj ntsuas qhov system, lub foundry tsis yog tsuas yog nchuav hlau - nws maps grain orientation tiv thaiv ntws cov kev taw qhia nyob rau hauv lub wax qauv sib dhos, kho preheat kub rau ib seem thickness, thiab tuav lub sij hawm solidification nyob rau hauv ± 90 vib nas this ntawm simulation tso zis.
Qhov no tsis yog theoretical. Nyob rau hauv ib qhov project tsis ntev los no rau European hydraulic actuator OEM, peb ntes tau 0.035 hli phab ntsa-thickness sib txawv ntawm tus tswv siv quav ciab * ua ntej * ceramic plhaub dipping-siv optical contour scanning es tsis txhob ntawm phau ntawv calipers. Qhov ntawd tau cawm peb lub lis piam ntawm kev rov ua haujlwm dua thiab tshem tawm cov khoom seem ntawm thawj 17 castings.
Vertical kev koom ua ke tsis yog lo lus buzz-nws yog tib txoj hauv kev los tswj microstructure kev ncaj ncees
Muaj ntau tus neeg muab khoom outsource tiav, kho cua sov, lossis txawm tias zaum kawg machining. Qhov ntawd cuam tshuam kev lav phib xaub-thiab qhia txog qhov hloov pauv tsis tau. Tus neeg teb xov tooj cua kub kho cua sov hauv ib lub tsev yuav nce siab ntawm 5 ° C / min; Lwm qhov kub ntawm 12 ° C / min. Ob leeg ntsib "AMS 2750E Chav Kawm 2" ntawm daim ntawv-tab sis tsuas yog ib qho xa tawm cov dej ntws zoo sib xws hauv cobalt-nickel alloys.
Qingdao Qiangsenyuan khiav tag nrho cov kauj ruam tseem ceeb nyob rau hauv ib lub ru tsev ISO: peev casting, multi-axis CNC machining (xws li 5-axis ib txhij contouring), nqus cua sov kho, thiab nto xov zoo li electropolishing los yog HVOF txheej. Tsis muaj handoffs. Tsis muaj cov ntaub ntawv qhov khoob. Tsis muaj "nws hais / nws hais" thaum lub hauv paus-ua rau kev tsom xam.
Qhov tshwm sim? Piston twj tso kua mis lub tog raj kheej cov tsev nyob uas dhau 100% kev ntsuas siab ntawm 1.5 × kev ua haujlwm siab - nrog xoom xau hla 212 units hauv qhov nruab nrab-ntev tsis ntev los no. Vim li cas? Vim tias tib pab pawg uas tau lees paub qhov kev tsim qauv gating kuj tau txheeb xyuas qhov kawg ID nto roughness (Ra ≤ 0.4 µm) thiab lees paub qhov kev faib tawm hardness (HRC 42-46) thoob plaws tag nrho qhov ntev ntawm qhov tho - tsis yog ntawm peb lub ntsiab lus.
Nws tsis yog hais txog casting qhov chaw - nws yog hais txog kev tsim nyog ua haujlwm
Qee lub tuam txhab aerospace peev casting kho GD&T ua kev kho kom zoo nkauj. Qingdao Qiangsenyuan kho nws raws li daim ntawv cog lus. Thaum kos duab hu rau txoj hauj lwm kam rau ua ntawm Ø0.05 hli ntawm rau bolt qhov txheeb ze rau lub dav hlau datum machined tom qab casting, lub khw hauv pem teb siv lub tshuab ntsuas kev sib koom tes nrog 0.001 hli daws teeb meem - thiab sau txhua qhov kev nyeem ntawv hauv cov ntaub ntawv ruaj ntseg txuas nrog cov khoom siv hluav taws xob.
Qhov theem ntawm kev nruj heev yog qhov tseem ceeb tshaj plaws nyob rau hauv geometry ua tau raws li kev ua haujlwm: winch center shaft rollers rau engineering tsheb yuav tsum tig qhov tseeb tsis pub dhau 0.01 hli tag nrho cov ntsuas ntsuas (TIR) nyob rau hauv dynamic load. Lub siab li qub xav kom tsis txhob muaj qhov tsis muaj qhov sib khi nrog qhov ua tiav qhov sib txuam ntawm elastomer lub compression teeb profile. Cov no tsis yog "zoo-rau-muaj." Lawv yog cov txheej txheem dhau / tsis ua tiav hauv txhua qhov kev soj ntsuam raws tu qauv.
Cov neeg siv khoom qhia peb qhov no ua rau kev tshuaj xyuas engineering sai dua - tsis qeeb. Ib lub tuam txhab North American twj tso kua mis txiav nws cov qauv iteration voj voog los ntawm 11 hnub mus rau 3.5 hnub tom qab hloov mus rau Qingdao Qiangsenyuan cov lus qhia txog kev tsim khoom thaum ntxov: kev txhais lus ntawm GD&T lub sijhawm, kev ua haujlwm siab ua qauv, thiab lwm cov ntaub ntawv tawm tswv yim raws li qhov tseeb hauv tsev kub-kho cov lus teb nkhaus-tsis yog cov ntaub ntawv dav dav.
Saib tom ntej: hybrid txheej txheem, tsis yog casting xwb
Cov pem hauv ntej tom ntej tsis yog qhov cub loj dua lossis ceev CMMs. Nws yog nruj dua fusion ntawm casting thiab machining-tshwj xeeb tshaj yog rau complex sab hauv geometry tsis yooj yim sua kom ua tiav los ntawm ob qho tib si txheej txheem. Tam sim no peb tab tom tsim hybrid workflows qhov twg peev-cam khwb cia ze-net duab undergo precision EDM drilling * ua ntej * kawg CNC milling-ua kom txias raws hauv turbine vaj tse nrog 0.3 hli phab ntsa thickness thiab 12: 1 nam piv.
Qhov ntawd yuav tsum muaj kev sib koom tes R & D sib sib zog nqus - tsis yog nrog cov neeg siv khoom xwb, tab sis nrog cov khoom siv tshawb fawb. Tam sim no, peb txoj kev txhim kho kev sib koom ua ke tsom mus rau kev txhim kho txoj hauv kev ua kom muaj zog rau qis-sigma-theem T800 variants, txo cov tshuaj tom qab cam khwb cia annealing lub sij hawm los ntawm 37% yam tsis muaj kev cuam tshuam txog kev tawm tsam.
Yog tias koj qhov kev tiv thaiv aerospace tom ntej no xav tau ntau dua qhov raug-yog tias nws xav tau kev coj tus cwj pwm zoo li qub, kev taug qab tag nrho, thiab xoom kam rau cov txheej txheem drift-koj xav tau aerospace peev casting Hoobkas ua rau lub hom phiaj tseem ceeb ua tiav. Tsis ntim. Tsis ceev. Muaj tseeb.
