Kev tsim cov khoom sib xyaw ua ke muaj qhov xav tau siab hauv kev ua haujlwm ntawm aerospace, tsheb, thiab kev tiv thaiv.Hauv cov haujlwm no, txo qhov hnyav thiab ua kom lub zog thiab ua haujlwm ntev yog qhov tseem ceeb hauv kev ua tiav txoj haujlwm.Txawm li cas los xij, qhov no yog kev siv sijhawm ntau thiab kim heev.
ExOne yog US-based additive manufacturing tuam txhab uas tshwj xeeb hauv kev lag luam 3D luam ntawv rau hlau thiab xuab zeb binder jetting.ExOne tam sim no tau tsim ib qho kev xaiv uas ua rau nws muaj peev xwm tsim cov complexcarbon fiber ntau or iav fibercov khoom siv txhawb zog, yog li zam kev siv cov cuab yeej kim los tsim cov geometry nyuaj.Qhov no txhais tau hais tias tsis tas yuav muaj cov txheej txheem pabcuam xws li cov kuab tshuaj, cov cuab yeej ua pa, lossis cov chisels.
Cov thev naus laus zis yog txheej txheem scouring uas siv cov khoom siv tab sis soluble 3D luam silica lossis ceramic xuab zeb cores.Raws li cov kev xav tau ntawm lub zog tshwj xeeb, 3D luam dej-soluble spraying tus neeg saib xyuas lossis Te ua ntej cov ntaub ntawv sib xyaw kom tawm ntawm qhov chaw tsis muaj qhov hws, thiab tom qab ntawd ntxiv cov khoom sib xyaw rau saum npoo los ntawm cov ntaub los yog superposition.Tom qab kho, cov khoom siv txhawb nqa soluble yog yooj yim rinsed nrog kais dej, tawm hauv qhov hollow composite ib feem.Thiab cov ntawv tshaj tawm yaj tuaj yeem rov siv dua thiab rov siv dua rau yav tom ntej 3D luam ntawv.
Rick Lucas, Chief Technology Officer ntawm ExOne, tau hais tias: "Qhov no yog qhov peb tau ua haujlwm rau qee lub sijhawm.Qhov no yog kev ua lag luam uas peb xav tau lub hom phiaj thiab nrhiav.Peb muaj engineers uas tau ua hauj lwm nyob rau hauv lub composites kev lag luam thiab to taub cov neeg.Muaj qhov xav tau tob dua rau cov xwm txheej quo ntawm kev tsim khoom sib xyaw. "
Txij li xyoo 2013, ExOne engineers tau tshawb pom thawj zaug uas lawv tuaj yeem sib txuas silica lossis ceramic grit rau cov dej-soluble hnyav ntawm 180 ° C.Cov teeb meem yog tsom rau txheej txheej txheej thiab siv cov nplaum dav hlau 3D luam ntawv los ua kom zoo dua cov khoom siv.Lucas piav tias: “Cov xuab zeb ceramic peb feem ntau siv yog ntxeem tau.Yog li yog tias koj tsuas yog kis cov khoom sib xyaw rau ntawm nws, autoclave nws nyob rau hauv siab thiab kub, thiab tom qab ntawd solidify nws;tom qab ntawd cov resin yuav nkag mus rau hauv cov khoom sib xyaw, nws tsis raug ntxuav tawm lawm.Yog li ntawd, peb yuav tsum tau siv ib txheej txheej ntawm nws los tiv thaiv qhov no tshwm sim.Nyob rau hauv lub xyoo dhau los los yog li ntawd, peb tau siv sij hawm ntau heev los txhim kho cov txheej txheem thiab txheej txheem, thiab kom ntseeg tau tias cov neeg siv khoom tau muab cov txheej txheem zoo.

Cov kav dej zaum kawg ua los ntawm cov khoom siv sib xyaw ua los ntawm cov tshuab dej-soluble
Hnub no,Txoj kev no yog siv los tsim cov pa roj carbon fiber ntau thiab cov iav fiber ntau cov khoom siv ntxiv, suav nrog cov dav hlau cua ducts, cov tso tsheb hlau luam siab, cov ntaub thaiv npog, cov ncej, thiab mandrels, tshwj xeeb tshaj yog rau cov qauv tsim uas yav tas los tsis tsim nyog rau kev tsim khoom los ntawm cov cuab yeej siv niaj hnub.Piv txwv li, REC, lub tuam txhab uas muab cov cua ducts rau cov nyoob hoom qav taub hnyav, tau siv ExOne's flushing tool los tsim mandrels rau cua ducts ntawm ob lub CH-35K helicopters, thiab ua tiav xa cov nyoob hoom qav taub no mus rau US Marine Corps rau kev ua qauv qhia.
Carbon fiber ntauCov kav dej sib xyaw ua tau siv 3D luam ntawv cov kav dej-soluble
ExOne tseem sim daws nrog lwm qhov kev sib tw uas tau ntsib nyob rau hauv cov txheej txheem autoclaving ib txwm muaj-thermal expansion thiab nws cov nyhuv ntawm ib feem geometry.Los ntawm cov txheej txheem dej ntws, cov hmoov tuaj yeem hloov tau los tswj kev nthuav dav thiab txo qis deformation.Piv txwv li, lub siab thermal expansion coefficient ntawm silica xuab zeb yuav haum rau qee cov ntaub ntawv, tab sis nyob rau hauv lwm yam uas yuav tsum tau ib tug tsawg thermal expansion coefficient, ceramic xuab zeb tej zaum yuav yog ib tug zoo xaiv.
Tam sim no, cov thev naus laus zis no feem ntau yog muab los ntawm kev thov los ntawm ExOne lub chaw saws me nyuam hauv Tebchaws Meskas.Tab sis lub tuam txhab tau hais tias nws cia siab tias yuav nthuav dav cov haujlwm no mus rau Tebchaws Europe yav tom ntej, thiab tuaj yeem koom tes nrog cov neeg koom tes raws li qhov kev thov loj tuaj.ExOne tseem tab tom ua haujlwm hnyav ntxiv txhawm rau txhim kho cov nplaum nplaum los ntawm cov tiam tom ntej, uas yuav muab lub zog ntau dua, kev daws teeb meem zoo dua thiab ua haujlwm kub dua.(Tau qhov twg los: Zhongguancun Online)
