Cov pwm loj - tuaj yeem tsim los ntawm hlau 3D luam ntawv?

1. Ib kauj ruam loj rau pem hauv ntej loj - nplai hlau 3D luam ntawv: los ntawm lub chaw sim mus rau lub Hoobkas
Lub tswv yim tseem ceeb tom qab hlau 3D luam ntawv yog txhawm rau txhawm rau cov ntaub ntawv hlau nyob rau sab saum toj ntawm ib leeg thiab siv siab - cov kab hluav taws xob zoo li lasers lossis cov kab hluav taws xob ncaj qha los ua cov txheej txheem nyuaj. Thaum nws los ua cov pwm loj, tau muaj kev nce qib loj hauv peb thaj chaw:
Kev nthuav dav ntawm cov khoom siv
LiM-X1500H radium laser cov cuab yeej tuaj yeem pwm daim uas yog 1290mm × 1180mm × 506mm. Nws tuaj yeem luam tawm ob qho tib si puag ncig thiab square seem ntawm aviation cav tib lub sijhawm. Muaj ntau cov qauv hollow thiab reinforcing ribs hauv qhov no. Cov txheej txheem ib txwm xav tau kev thaiv kev ua haujlwm thiab kev sib txuas, thaum SLM thev naus laus zis txiav lub voj voog tsim khoom ntau dua 50% thiab siv ntau dua 90% ntawm cov khoom siv los ntawm kev sib xyaw ua ke. Qhov tseem ceeb tshaj, nws LiM-X800H+ cov cuab yeej, uas tau tawm xyoo 2024, muaj qhov siab ntawm qhov siab ntawm 2.5 meters thiab tuaj yeem ua titanium alloy kauv cov khoom siv uas yog 418mm × 362mm × 2210mm hauv qhov loj. Qhov no ua pov thawj tias cov khoom siv ruaj khov txaus los ua cov khoom loj thiab lub teeb.
Kev sib koom tes ntawm ntau lub lasers thiab cov txheej txheem txhim kho
Kev tswj cov thermal stress yog ib qho teeb meem rau loj -scale printing. Thaum luam ntawv tshaj 6-meter titanium alloy dav hlau thav duab, Leiming laser txais ntau-laser kev sib koom tes thev naus laus zis kom tau txais qhov chaw laser sib tshooj rau 30%. Thaum siv nrog cov hmoov dynamic faib mus kom ze, qhov no txo ​​qis cov kev ntxhov siab seem los ntawm 40%, uas ua kom paub tseeb tias qhov loj me ntawm qhov loj (6295mm × 2198mm × 614mm) yog qhov tseeb. Lub topology optimization tsim ntawm aluminium alloy tshav kub exchanger (569mm × 527mm × 512mm) kuj qhia tau hais tias yuav ua li cas SLM tshuab yuav siv tau los ua ke cov ndlwg channel thiab lub ntsiab qauv. Qhov no qhia tau hais tias hloov tau yooj yim npaum li cas rau txoj kev txias txias.
Innovation nyob rau hauv hybrid manufacturing thiab post-processing
Laiming Laser tau tsim kho ntsuab laser additive manufacturing tov rau siab tiv thaiv- cov ntaub ntawv hlau xws li tooj liab ntshiab. Qhov system no tau ua tiav kev luam tawm ntshiab tooj liab thrust chambers thiab cua sov dissipation fin lug. Txoj kev no mus dhau qhov txwv tsis pub nqus ntawm cov lasers liab tsis tu ncua ntawm cov ntaub ntawv uas hnov ​​​​mob sai, ua rau kev luam ntawv ntawm tooj liab ntshiab peb zaug ntau dua. Qhov saum npoo roughness yog Ra<0.8 μ m, which meets the strict requirements for heat conductivity in the aerospace industry. At the same time, unique connecting technology has been created to satisfy the needs of huge moulds once they have been processed. Laser welding makes it easy to connect 3D printed pieces with traditional machining bases. This makes the structure stronger and speeds up the manufacturing process.
2. Kev lag luam siv cov pwm tsim loj heev: los ntawm kev sim cov tswv yim los ua kom muaj ntau ntau
Hlau 3D luam ntawv tau siv nyob rau hauv ob peb lub siab -kawg lag luam los ua pwm loj, thiab nws cov nqi tau raug pov thawj los ntawm qhov tseeb - piv txwv hauv ntiaj teb:
Lub teeb yuag thiab ua haujlwm sib koom ua ke hauv Aerospace
Qhov kev xav tau ntawm lub teeb yuag drone lub hauv paus hauv qhov qis - qhov siab ntawm kev lag luam tau ua rau kev siv loj - nplai 3D luam ntawv. Luming Laser siv LiM-X260A los luam titanium alloy drone ncej uas yog 153mm × 153mm × 25mm thiab hnyav dua 0.3kg. Topology optimization txiav cov naj npawb ntawm cov khoom thiab cov txheej txheem ntau lawm los ntawm 12 mus rau 3. Lub voj voog luam ntawv tseem raug txiav mus rau 5 teev. Qhov xwm txheej no qhia tau hais tias hlau 3D luam ntawv tuaj yeem pom qhov sib npaug ntawm qhov hnyav thiab lub zog ntawm cov qauv, uas yog qhov tseem ceeb heev rau kev ua kom cov khoom siv dav hlau ua haujlwm zoo dua.
Cov khoom siv hluav taws xob: muab tso ua ke cov tshuab cua txias hauv ib thooj
Kev tsim ntawm cov cua txias channel hauv cov pwm kub hloov pauv loj muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov khoom siv hluav taws xob nuclear. Cov txheej txheem ib txwm xav tau ntau pua lub qhov txias txias drilled rau hauv pwm. Hlau 3D luam ntawv, ntawm qhov tod tes, tsim ib qho kev sib haum xeeb dej txias uas txiav qhov kev ncua deb ntawm coolant ntws los ntawm 60% thiab boosts tshav kub hloov efficiency los ntawm 25%. Piv txwv li, SLM thev naus laus zis tau siv los luam cov pwm rau lub tshuab hluav taws xob hluav taws xob nuclear uas muaj cov dej txias txias uas tsuas yog 2 hli dav. Cov pwm no yog 1.2 meters siab thiab muaj kev tswj qhov kub thiab txias, uas daws qhov teeb meem ntawm cov khoom qaug zog uas tshwm sim thaum cov khoom kub dhau ntawm cov txheej txheem ib txwm muaj.
Automotive Manufacturing: Kev hloov pauv sai rau cov pwm loj
Feem ntau lub tsheb vaj huam sib luag pwm loj dua 3 meters, thiab cov txheej txheem casting ib txwm xav tau kev sim ntau lawm ntawm 6 mus rau 8 lub lis piam. Thiab hlau 3D luam ntawv txiav lub sij hawm nws yuav siv sij hawm los ua ib tug pwm core mus rau ob lub lis piam los ntawm kev tsim nws ncaj qha. Ib lub npe tshiab ntawm lub zog tshiab tau ua haujlwm DED thev naus laus zis los kho cov tuag loj-casting pwm. Cov hnav- txheej tiv thaiv ntawm cov pwm saum npoo tau kho hauv 48 teev los ntawm kev pub mis thiab yaj hmoov rau tib lub sijhawm. Cov txheej txheem kho yog HRC52 nyuaj, uas yog 20% ​​nyuaj dua li txoj kev vuam raug. Qhov no txhais tau hais tias cov pwm yuav tsis hloov cov duab vim yog lub tshav kub cuam tshuam cheeb tsam.
3. Cov Kev Sib Tw Txuj Ci thiab Cov Qauv Yav Tom Ntej: Los ntawm kev tawg ntawm ib qho taw tes rau kev txhim kho ib puag ncig
Txawm tias loj - nplai hlau 3D luam ntawv muaj peev xwm ntau, nws tseem muaj peb qhov teeb meem loj uas yuav tsum tau daws ua ntej nws tuaj yeem siv dav:
Tswj cov nqi thiab kev ua haujlwm ntawm cov khoom siv
Kev tsim pwm xav tau cov ntaub ntawv uas tau raug quenched thiab hardened, tab sis 3D luam ntawv tuaj yeem ceev cov ntaub ntawv, uas tuaj yeem ua rau lawv nkig. Txoj kev daws teeb meem yog ua kom qis -kev nyuaj siab martensitic aging steel hmoov thiab cua sov- kho nws kom nws nyuaj rau 52HRC. Siv cov txheej txheem luam ntawv gradient, cov txheej txheem nyuaj yog muab tso rau ntawm cov pwm saum npoo thaum khaws cov matrix tawv hauv qhov chaw tseem ceeb. Qhov no sib npaug hnav tsis kam thiab cuam tshuam tsis kam.
Kev ntsuam xyuas kev ruaj ntseg thiab kev ua tau zoo hauv cov txheej txheem
Thaum luam ntawv rau ntawm qhov loj me, qhov kub thiab txias hauv zos lossis cov hmoov paug tuaj yeem ua rau tus nqi txhaum mus. Kev lag luam tab tom thawb rau hauv -situ saib xyuas thev naus laus zis, xws li LiM-X800H+ cov cuab yeej uas ua ke nrog cov duab hluav taws xob thermal thiab yaj lub pas dej ua ke nrog lub laser radium. Cov tshuab no tuaj yeem hloov lub zog ntawm lub laser hauv lub sijhawm tiag tiag thiab txiav cov lej ntawm qhov tsis xws luag los ntawm 3% mus rau 0.5%. Nyob rau tib lub sijhawm, AI-raws li cov qauv kev kwv yees tsis raug tuaj yeem pom muaj kev pheej hmoo ua ntej los ntawm kev saib cov ntaub ntawv luam tawm yav dhau los, uas pab ua kom zoo ruaj khov dua.
Kev sib koom tes thiab kev tsim qauv hauv kev lag luam saw
Ua cov pwm loj loj yuav tsum sib txuas ob peb kauj ruam, xws li 3D luam ntawv, CNC machining, thiab kev kho cua sov. GF Processing Solutions tau tshaj tawm "hybrid qhov chaw" kev tsim cov kev daws teeb meem uas siv cov chaw ua haujlwm automated rau seamlessly muab cov txheej txheem rho tawm thiab ntxiv cov txheej txheem. Qhov no txiav lub sijhawm nws siv los ua pwm los ntawm 40%. Kev taw qhia ntawm ISO / ASTM 52921 tus qauv kuj tau teeb tsa cov qauv rau yam tseem ceeb xws li qhov ntev ntev thiab qhov roughness rau loj - nplai hlau 3D luam ntawv. Qhov no ua rau nws muaj peev xwm rau kev lag luam siv cov cuab yeej siv no rau ntawm qhov dav.
