Tuaj yeem hlau 3D luam tawm tsim cov roj ntau cov roj channel?

1. Cov ntsiab cai: Kev hloov pauv raug los ntawm cov qauv digital rau cov qauv txheej txheem tangures.
Cov khoom muaj nqis ntawm kev tsim khoom ntxiv yog dab tsi ua rau cov hlau 3D luam tau rau kev ua kom muaj cov dej raws. Piv txwv li, cov txheej txheem ntws rau xaiv laser melting (slm) thev naus laus zis tuaj yeem tawg rau hauv peb kauj ruam:
Cov qauv qauv: Siv CAD software ua rau peb {{{0} {{- seem ntawm cov duab, thiab cov npoo av. Piv txwv li, sino fais lub sib ntau - protectional valve siv kev pab pawg neeg tshwj xeeb kom haum los ntawm 40%.
Fawm kib: Ua kom ua txoj kev ua laser scanning, txiav cov qauv rau hauv cov khaubncaws sab nraud pov rau cov khaubncaws sab nraud pov tseg uas yog 20 txog 50 μm tuab} Axis. Platinum thev naus laus zis txheej txheem lub tsev qiv ntawv muaj peev xwm txuas phim lub zog laser, ntsuas nrawm, thiab lwm yam chaw rau cov khoom sib txawv. Qhov no ua rau qhov tseeb ntawm cov channel phab ntsa tuab nyob rau hauv ± 0.05mm.
Melting txheej los ntawm txheej: lub siab - Lub Zog} Lub Zog Laser Beam xaiv melts hlau hmoov raws txoj kev thaum muaj kev tiv thaiv los ntawm cov roj hauv cov roj. Qhov no tsim cov khoom khov kho los ntawm cov txheej txheej tso rau sab saum toj ntawm ib leeg. Hluav Taws Xob Beaving Melting (EBM) Technology Siv Hluav Taws Xob Puam Soj Ntsuam Hauv Ib puag ncig. Nws yog qhov zoo rau kev ua cov khoom siv uas nyuaj rau cov txheej txheem, xws li siab- kub alloys uas tau siv los ua cov dav hlau tshuab tuaj.
Qhov no "los ntawm kos" txoj kev tsim khoom puas deb nrog qhov kev xav tau ntawm cov cuab yeej thiab cov cuab yeej hauv cov txheej txheem ib txwm muaj. Nws tseem tuaj yeem tsim ncaj qha los tsim ib qho kev nyuaj ntws channel, xws li Kong}} {{1} {2} Zoo li ntws raws.
2, Situation for use: Breakthrough practice in the realm of high-end manufacturing
Aerospace: ib qho kev siv rooj plaub yog lub txias channel txias ntawm lub turbine hniav hauv lub cav aviation. Txhawm rau muab cov hlab txias siv cov txheej txheem tsoos, koj yuav tsum tau tho lossis weld lawv ua ke. Qhov no tej zaum yuav ua rau xas thiab ua kom txias dua ua tau zoo. Thiab koj yuav siv cov hlau 3D luam kom ua rau sab hauv chav Labyrinth Flun channel uas cia cua txias ntxig hniav saum npoo. Qhov no zoo heev txhim kho lub cav thrust - rau {{6} Qhov hnyav} qhov hnyav. Lub cav hluav taws xob roj ua ke ua los ntawm ge siv cov tshuab ntsuas hluav taws xob 3D ua ke rau hauv ib qho, uas ua rau nws 25% sib zog dua thiab 15% ntxiv roj nraaj.
Biomedical: Tus qauv ntawm cov kua dej hauv cov dej hauv cov pa tawm hauv cov pa thaiv hniav ncaj qha muaj cov nyhuv ncaj qha rau cov ntaub so ntswg zoo. Piv txwv li, 3D {{{-} cov luam tawm hip muaj cov pob txha biomimetic cov kab mob biomimetic Cov lus qhia hauv cov neeg kuaj mob pom tau tias lub sijhawm nws yuav siv sij hawm rau cov pob txha mus sib xyaw yog txiav hauv ib nrab. Maxwell Medical, Lub tuam txhab ntse tsim hauv Xi'an, tau tsim tawm cov khoom siv hluav taws xob hauv sab hauv uas muaj kev cuam tshuam nrog kev sib tshuam ntawm kev sib tshuam. Qhov kev txiav cov teeb meem no tom qab phais tas 30%.
Zog thiab Power: 3D {{{{- Cov khoom siv kub ua tau zoo ntawm kev ua kom sov ntawm cov khoom siv kub ntawm cov dej ntws ntawm cov tshuab cua txias ntawm nuclear reactors. Xi'an OUZHong Tshuab tsim cov titanium alloy Flow channel siv micrometer- theem txaus ntsuas Channel tsim. Qhov no ua rau qhov ntsuas kub ntawm tib lub tshuab ua siv lestal nyob rau hauv ± 0.5 degree.
3, thev naus laus zis ntug: ib ob chav sib tawg hauv kev tsim txoj kev ywj pheej thiab kev ua tau zoo dua qub
Kev tsim kev tawm txoj kev ywj pheej: Cov txheej txheem ib txwm muaj txwv los ntawm cov ces kaum ntawm cov pwm twg yuav muaj cov khoom siv tau. Tus tsim qauv ntawm tus neeg khiav kuj yuav tsum tau coj mus rau hauv tus account yooj yim npaum li cas nws yog los tsim tau} d luam tawm tuaj yeem ua rau ntws raws ntawm ib lub kaum sab xis los yog nkhaus. Piv txwv li, sino fais fab valve thaiv rau cov khoom siv tsis muaj kev nkag rau cov thawj 12 tus txheej txheem qhov ua rau 3 nrag ntws tawm. Qhov no txiav lub ntim los ntawm 60% thiab lub siab poob ntawm 25%.
Ua kom zoo tshaj plaws cov khoom siv: hlau 3D luam tawm tuaj yeem tsim cov qauv ntim cov qauv zoo thiab ua cov khoom muaj zog vim tias nws ua tau sai. Qhov chaw txaus siab qhov chaw ua los ntawm TC4 titanium alloy los ntawm platinum Lite muaj lub zog tensile muaj lub zog tensile muaj 11%, uas muaj zog dua li kev lom zem. Topology Optimize tsim kuj tseem ua rau cov khoom 30% sib zog, uas ua tau raws li kev lag luam Aviation "High {8} lub zog."
Tus nqi thiab lub sijhawm txuag hauv kev tsim khoom: Ua lub cev muaj zog siv 12 kauj ruam, thiab tuaj yeem siv sijhawm li 6 lub hlis tuaj yeem tig cov khoom nyoos rau hauv ib qho chaw. Sino fais fab thaiv qhov project tau txiav lub sijhawm xa mus rau ob asthiv thiab qis dua tus nqi ntau dua rau cov khoom lag luam me me.
4. Cov teeb meem kev ua haujlwm thiab txoj hauv kev kom tau ib puag ncig lawv
Hlau 3D luam tawm muaj ntau lub peev xwm rau kev ua kom muaj kev ua kua taus, tab sis nws tseem muaj peb qhov teeb meem loj los daws:
Tswj txog ntawm qhov chaw nruab saum npoo: qhov chaw saum npoo ntawm cov channel txaus ua los ntawm cov txheej txheem slm yog ib txwm ra250}} 400} 400 μ m. Yuav kom ua tiav cov qauv sealing, qhov no yuav tsum tau coj mus rau RA10 μ m lossis qis dua siv cov elecolytic polishing lossis txhaj tshuaj classen. Xi'an Jiaotong University tsim Ultral thev naus laus zis uas tuaj yeem ua rau cov Flow channel nto RA50 μ m, uas txiav rau ntawm cov kauj ruam xav tau tom qab kev ua tiav.
Nrhiav tej yam tsis xws pom nyob rau hauv Flow channel: nws nyuaj rau pom tsis xws luag zoo li tsis muaj fusion thiab porosity. Platinum khoom siv tau tsim muaj kev lag luam CT scanning cov khoom siv uas tuaj yeem nrhiav cov khoom tsis txaus sab hauv uas yog 0.1mm. Tus yam ntxwv kom pom tau tus nqi tau nce mus txog 99.9% thaum siv nrog AI cov duab lees paub txoj kev.
Multi -}}}}}}}} Cov khoom siv sib xyaw ua haujlwm: ua kom cov kua dej nyuaj, zoo li cov qauv sib xyaw ua ke thiab cov qauv uas muaj zog heev. Xi'an Ouzhong Technology Lub Laser Arc Composite Tshuab Luam Ntawv tau ua rau cov khoom siv Alloy ntws tau txuas rau hauv txoj kev uas tsis muaj kev sib tw. Cov thev naus laus zis no muaj lub zog tensile ntawm 400 MPA, uas yog dab tsi marine engineering kev xav tau.
