Yuav xaiv li cas xaiv cov hlau 3D luam ntawv luam tawm cov khoom siv hauv kev lag luam raug?

1, Kev txuam kev sib txuam: Tau txais mus rau hauv qab ntawm cov kev xav qab qab cov txheej txheem sawv cev
Tus Qauv Tam Sim NoHlau 3D PrintingTshuab muaj "peb ceg txheem" ​​qauv "
Laser xaiv melting (LPBF): EOS M 400-4 plaub lasas kev tswj hwm cov txheej txheej txheej txheej txheej txheej ntawm 20 thiab 50 μm siv 200-1000000 laser. Cov kab ke no zoo rau kev ua kom zoo nkauj heev channel qhov chaw hauv Aerospace kev lag luam. Qhov zoo tshaj plaws txog nws yog tias koj tuaj yeem tswj hwm microstructure. Piv txwv li, Titanium alloy central flange strip uas platinum quab yuam ua rau lub sij hawm laser loj los ntawm kev hloov lub zog laser, uas ua rau nws 18% muaj zog tiv thaiv kev qaug zog.
Hluav Taws Xob Beamting (eb {{}} pbf): Arcam Q20lus Lub Cav ntawm ib qho nrawm ntawm 1000mm ³ / h hauv lub tshuab nqus ntawm 650 degree. Qhov no ua rau nws zoo heev rau kev txua high - kub ntawm tsob hluav taws xob. Nrog cov thev naus laus zis no, ge aviation tau txiav lub sijhawm nws yuav ua rau tib lub tshuab ua kom tawg ntawm 12 lub lim tiam thiab txo tus nqi ntawm cov kab ke sib txawv rau 0.03%.
Cov tshuaj nplaum nplaum nplaum (bj): lub desktop hlau khw txheej txheem siv Droplet txau siv tshuab siv tau 2000 tee ntawm adhesive ntawm cov nplaum ib ob. Nws mam li mus dhau 1200℃degree sintering sintering cov txheej txheem, uas qhia tau tias nws pheej yig dua los ua cov cuab yeej pwm. Qhov kev siv tshuab no yog siv los ntawm qee lub tsheb tsim los ua kev txhaj tshuaj pwm nrog conformal txias channels. Qhov kev txiav tawm ntawm qhov kev tsim kho lub sijhawm los ntawm 28% thiab ua cov pwm thaum 3.2 zaug ntev dua li cov hau kev dhau los.
Tseem ceeb rau xav txog ua ntej xaiv:
LPBF txheej txheem yog qhov zoo dua rau kev sib tw sab hauv cov kab noj hniav.
Nws tau qhia tias cov cuab yeej nqus hluav taws xob muaj peev xwm kuaj xyuas kom high - kub cov ntaub ntawv (tsawg dua los yog sib npaug zos rau 5 × 10⁻ 10.
Rau qhov loj - nplai ntau lawm, shrinkage tus nqi ntawm bj thev naus laus zis thaum lub sijhawm (feem ntau 1.8-2.2%) yuav tsum tau kuaj.
2, Cov Khoom Siv Tau Zoo: Qhov tseem ceeb rau kev tau txais cov txheej txheem yav dhau los
Muaj ntau dua 20 cov ntaub ntawv uas ua tag nrho cov kab ke rau cov hlau 3D luam tawm, suav nrog 17} {} {} {}} {V titanium ineloy, thiab lwm tus. Thaum xaiv, koj yuav tsum them nyiaj zoo rau:
Kev yoog cov yam ntxwv zoo: EOS M 300-4 yog qhov zoo tshaj plaws ntawm cov neeg ncaj ncees dispersing fwj nrog lub sphererity ntawm 90% lossis siab dua thiab poob qis tus nqi ntawm 25s / 50G lossis qis dua. Lub tuam txhab kho mob uas siv cobalt Chromium alloy hmoov nrog spherericity ntawm 85% pom ib tus naj npawb ntawm cov txheej txheem sib tw sib tw.
Muaj peev xwm ua cov txheej txheem ntau yam: fartsoon fs121m-8 tuaj yeem hloov zuj zus ntawm titanium alloy, thiab pwm hlau ua tsaug rau cov modular hmoov noj txheej txheem. Nws tuaj yeem ua qhov no tsawg dua li 45 feeb, uas yog zoo meej rau me me pob manufacturing ntawm ntau hom.
Ua cov ntaub ntawv tshiab: lub platinum Lite BLT - Sygic hmoov kis tshuab uas tuaj yeem ua rau nanocrystalline hmoov ntau thiab tsawg ntawm 15 thiab 53 μm. Qhov no pab nrog lub tshuab luam ntawv siab - Lub zog aluminium alloy A20X thiab muab cov ntu ntawm lub zog tensile ntawm 620mpa.
Yuav kuaj li cas:
Nug cov neeg tsim khoom ntawm cov khoom siv los muab cov ntawv teev npe sau ntawv pov thawj rau koj, xws li NASA MFS-30301 tus qauv.
Ua me me - scation test ntau los xyuas cov hmoov hmoov (LPBF Teecology: 45-65% PBF Technology: 70-85%).
Raws li cov ntaub ntawv sib txawv, tshawb xyuas cov qib ntawm kev nyuaj siab tseem ceeb (pom zoo 200mpa).
3, kev tshuaj xyuas ntawm cov khoom siv tau ua haujlwm: kev hloov ntawm kev ua tau zoo ntawm ib lub tshuab rau kev ua haujlwm ntawm tag nrho cov system
Xaiv Industrial -} Cov khoom lag luam qib, koj yuav tsum teeb tsa ib peb -} txoj kev ntsuas qauv:
Qhov ntsuas ntawm ib lub cav tshuab hluav taws xob:
Ceev ntawm Scanning: Huashu's 12 laser system lub fs811m {3 yog lub siab-tech scanner uas tuaj yeem yog cuaj zaug sai dua li ib qho laser.
Yuav ua li cas ceev ceev lub tsev nce: g g ge additive lub tswv yim m2 series tuaj yeem ncav cuag 45 lub log ³ / h, uas yog txaus ntawm lub tsheb cav tsheb cav.
Qhov loj me ntawm cov pwm: Moulding muaj peev xwm ntawm platinum blert - s1000 mm, uas txhais tau tias nws tuaj yeem luam tag nrho cov dav hlau ntawm lub dav hlau txhua lub sijhawm.
Kab ntawm cov khoom lag luam uas sau nws tus kheej: uas yog tsim los ntawm EOS thiab Siemens ua haujlwm ua ke, zoo nkauj ua haujlwm ntawm cov hmoov thiab muab tso rau qhov chaw los ntawm Agv. Qhov no nce kev siv cov khoom siv rau 82%.
Dig Tshaj Tawm System: Lub renishaw Am400 los nrog Renam Flex software uas tuaj yeem qhia tau kev ntxhov siab yuav kis tau kev ntxhov siab npaum li cas thaum lub sijhawm luam ntawv hauv lub sijhawm. Qhov no txo ​​tus nqi ntawm cov kab nrib pleb kom tsawg dua 0.5%.
Tswj Zog Siv:
LPBF cov khoom siv feem ntau siv 8 txog 12 kw / h ntawm lub zog, thiab cov txiaj ntsig ntawm lub zog siab ntawm cov nroj tsuag lub zog xa khoom yuav tsum tau ntsia.
Platinum thev naus laus zis rov siv hluav taws xob tuaj yeem siv cov khib nyiab los ntawm cov cuab yeej los ntawm cov hmoov nplej ua kom sov, uas txiav txhua lub zog siv los ntawm 18%.
Piv txwv ntawm cov txiaj ntsig kev suav: Lub dav hlua khov kho saib peb qhov kev daws teeb meem sib txawv:
Tus nqi ntawm ib daim ntawm ib txwm muaj tsib - Axis machining machining yog ¥ 85,000 lub sijhawm yog 45 hnub.
LPBF PRINTING: ¥ 32,000 ib chav nyob, 7 hnub los ua tiav (cov kev xav tau tshaj tawm {{} kev ua)
Chav tsev them nqi ntawm eb - paf luam ntawv yog ¥ 28,000, thiab lub sijhawm ntev yog 5 hnub (ze rau kev tsim cov khoom).
Txoj kev xaiv kawg yog eb {- pbf technology, uas tau tsa lub xyoo tsim khoom muaj peev xwm los ntawm 1200 daim thiab sped cov khoom lag luam turnover los ntawm 400%.
4, system rau kev ua kom zoo: tau txais mus rau hauv qab ntawm kev ntseeg tau engineering
Rau industrial -} Cov khoom lag luam qib, plaub theem ntawm kev tswj kom zoo yuav tsum tau teeb tsa:
Saib xyuas cov txheej txheem:
Saib xyuas cov pas dej Molten: EOS M 400C muaj cov pyrogenisis sensor uas tuaj yeem ua kom lub qhov muag kub ntawm 1000 molten pas dej nyob rau hauv lub sijhawm tiag tiag, uas pab kom qoob loo grain.
Pom hmoov: The Huashu High Tech FS273m ua haujlwm ib Laser Profiler kom kho cov txheej ntawm txhua lub voj kaw thaum 0.01 hli.
Sib sau rau post - kev:
Kub iSostatic nias (HIP): Koj yuav tsum txheeb xyuas tias cov khoom loj me thiab cov khoom luam tawm yog ze rau ib leeg li ntawd (piv txwv li, quintus QIH-{mmm hauv lub taub).
Kev kho uas siv cov khoom siv tshuab xaws uas: kom muaj cov khoom siv nyias khov kho tshiab
Kuaj tias tsis muaj kev puas tsuaj:
Muaj Kev Lag Luam CT: YXLon FF35 cov khoom siv tuaj yeem nrhiav cov khoom tsis xws luag xws li 0.05mm, uas yog qhov kev lag luam aerospace yuav tsum muaj.
Kev kuaj nrog Eddy cov dej khov: eddyfi tshuab thev naus laus zis tuaj yeem nrhiav cov kab nrib pleb hauv titanium alloys li tob li 0.02mm.
Kev siv rau cov qauv ntawv pov thawj:
Aerospace: AC7114 / 3 LOS NTAWM NADCAP
ISO 13485 thiab ASTM F3184 rau cov cuab yeej siv kho mob
VDA hauv kev lag luam tsheb 6.3 tshuaj xyuas ntawm cov txheej txheem
