Dab tsi yog qhov tseem ceeb ntawm kev hlau 3D luam tawm hauv pwm tsim khoom?

1. Cov ntsiab cai: Hloov digital cov qauv rau cov khoom hlau
Lub tswv yim tseem ceeb tom qab hlau 3D luam tawm yog "digitally tau tsav fideled melting thiab stacking." Cov txheej txheem tseem ceeb hauv cov txheej txheem suav nrog cov qauv ua haujlwm, hmoov kis, zog melting, thiab interlayer tsev neeg. Piv txwv li, cov nrov laser xaiv melting (SLM) thev naus laus zis:
Txiav sib nrug 3D qauv thiab qauv qauv
Tom qab siv CAD software los ua tus qauv 3D ntawm cov pwm, nws yuav tsum tau pauv mus rau hauv slicing software rau cov ntaub ntawv hla los ua 2} ntu cov ntaub ntawv uas yog 20 txog 50 microns tuab. Txoj kev npaj lub tswv yim siv tus ntoo khaub lig- seem ntawm lub taub hau scanning ntawm lub taub qhuav kom tsis txhob muaj kev ntxhov siab ntawm cov khaubncaws sab nraud povtseg. Piv txwv li, thaum ua kev txhaj tshuaj pwm nrog conformal txias txias channels, cov algorithm yuav ua tib zoo tswj cov kev txiav txim uas cov kauv channel yog scanned kom paub tseeb tias tus txias txias ntws zoo.
Melting ntawm lub hmoov txaj thiab tsim cov khaubncaws sab nraud povtseg
Cov cuab yeej tso cov txheej hlau ntawm cov hlau hlau (xws li titanium alloy, txhuas alloy, lossis pwm hlau) sab hauv cov moulding chamber. Lub nqaj laser ces yaj cov hmoov raws txoj kev teeb tsa los ua pas dej ntawm cov hlau ntawm molten. Tom qab lub pas dej me qhuav txias thiab ua kom sai sai, ua tiav platform yog txo qis los ntawm ib txheej tuab. Lub voj voog ntawm kev faib tawm hmoov, yaj nws, thiab soliding nws yog txuas ntxiv mus kom txog thaum cov hlau pwm nrog lub ntom ntawm 99.9% yog ua. Txoj kev no tsis xav tau pwm lossis kho kom haum, thiab nws yuav ua rau muaj cov kab noj hniav sab hauv ncaj qha, zoo li tuag- Cashter txhawb cov pwm.
Kev sib koom tes kev sib koom tes hauv lub realm ntawm multi - physics
Thaum lub sij hawm cov txheej txheem luam ntawv, cov yam ntxwv nrog rau qhov ntsuas kub ntawm cov pa yaj, cov pa oxygen, thiab cov pa roj cua ntawm cov hmoov yuav tsum tau saib xyuas lub sijhawm tiag tiag. Piv txwv li, Yunyao Shenwei lub kaw {{1} kev tswj lub zog thermal (200-1000Mm / s) Qee lub tuam txhab ua haujlwm ntsuab laser thev naus laus zis ua kom lub zog ua kom haum rau cov ntaub ntawv uas cuam tshuam ntau lub teeb, zoo li tooj liab.
2. Kev ntsuas hluav taws xob: daws peb qhov teeb meem loj tshaj plaws nrog cov tshuaj pwm ua
Los ntawm kev hloov pauv ntawm txoj kev ua, hlau 3D luam ntawv ntxiv peb qhov tseem ceeb tshiab rau cov pwm lag luam:
Ib txoj kev txhim kho loj heev hauv kev tsim kev ywj pheej
Qhov "tawm ntawm kev ua tiav" xwm ntawm Drilling, Milling, thiab lwm cov txheej txheem ua rau nws nyuaj ua cov pwm nyob hauv txoj kev ib txwm muaj. Txias charnels feem ntau ua raws li cov kab ncaj lossis yooj yim polylines. Qhov no txhais tau tias kev txhaj tshuaj molding qhov tsis txias (qhov kub muaj ntau dua 30 degree)} dendritic veins kom haum rau geometry ntawm pwm Chamber. Audi tau siv cov txheej txheem no ua kom tuag - cast, shipting kev txhaj tshuaj moulding los ntawm 35%, thiab qis dua ntawm kab ntawv ntawm 8% mus rau 1.2%.
Ob zaug nrawm thiab ob zaug uas pheej yig los ua
Piv txwv li, kev txhaj tshuaj tsheb pob pwm: nws yuav siv sijhawm 6 lub lis piam rau ib txwm siv cnc machining kom ua rau Electrode, ua hluav taws xob tshem tawm cov machining, thiab lwm kauj ruam. Nws tsuas yog siv sijhawm li 72 teev rau 3D luam tawm, thiab cov khoom siv siv tau siv tau nce los ntawm 25% mus rau 95%. Rau cov pob zeb me me ua pwm, xws li cov xwm txheej rau cov cuab yeej kho mob, tus nqi luam ntawv 3D luam ntawv tsawg dua ib qho dua li kev coj ua. Qhov no ua rau nws zoo tagnrho rau cov qauv ua qauv thiab theem kev sim ntau lawm.
Ua kom zoo ua haujlwm ntawm cov ntaub ntawv thiab cov qauv
3D luam ntawv tau nrawm nrawm (txias tus nqi li 10 ^ 6℃/ s) tuaj yeem tsim cov qauv ua kom zoo dua qub thiab tiv taus kev hnav. Piv txwv li, H13 pwm hlau ua nrog SLM thev naus laus zis muaj lub zog qaug zog lub neej uas yog 2.3 npaug ntev dua li cov khoom forged. Qhov no ua rau nws zoo rau tuag {{}}} meteting cov xwm txheej nrog cov khoom hnyav. Tsis tas li, gradient cov khoom siv luam ntawv yuav tso siab - Hardness Txheej (xws li txhais tau tias "ib qho khoom siv rau ntau yam kev siv."
3. Siv cov xwm txheej ntau yam suav nrog cov kev sib xyaw ua ke txias thiab ua haujlwm sib xyaw.
Hlau 3D luam tawm tau ua qhov cuam tshuam loj rau ntau yam ntawm cov pwm ua, tsim cov kev daws teeb meem kev daws teeb meem:
Txhaj pwm pwm: kev siv loj ntawm cov khoom siv hluav taws xob txias channel
Hauv lub tsev loj hauv tsev pwm, 3D {{{{-}}}}}}} sew cov dej txias los ntawm 45 vib nas this mus 28 vib nas this thiab tshem ntawm Weld flaws. Ib lub tuam txhab tsim cov kwj dej biomimetic rau cov cua vaj huam sib luag rau cov cua vaj huam sib luag ntawm 0.02mm, uas yog tib yam li daim iav.
Tuag casting pwm: tus qauv tsim nrog cov ntxaij thiab lub teeb hnyav
Txhawm rau ua kom muaj kev sib haum xeeb kab hauv qab kab ke siv tsoos tuag - Casting pwm, koj yuav tsum muab tso ua ke ntau tshooj. Siv cov luam ntawv 3D, koj tuaj yeem ua cov pwm nrog cov qhov hla ib leeg thiab nyias {}}} phab ntsa rone ib zaug. Piv txwv li lub tsheb loj lub tsheb roj teeb roj teeb {}} Casting tsim qauv los txiav qhov hnyav los ntawm 42%. Lub neej pwm tseem txuas ntxiv ntawm 50,000 zaus mus rau 120,000 zaus nrog 3D luam tawm canals.
Roj Hmab Log: Ua cov qauv thaiv nrog qhov tseeb zoo
Yav dhau los, nws yog ib qho nyuaj ua kom cov log tsheb nrog micrometer {{qib qhov tseeb, zoo li nag los yog ib qho xwb 1.5mm dav. Siv siab {{3} Precision Laser Tswj, 3D luam tawm tuaj yeem thaiv cov qauv deformation uas tuaj yeem tshwm sim nrog hluav taws xob tshem tawm tshuab. Cov qauv rov ua dua qhov tseeb ntawm F1 sib tw log pwm pwm ua los ntawm qee lub tuam txhab yog ± 0.01 hli, uas yog lub thoob ntiaj teb tsheb kauj vab.
4. Kev Lag Luam Txuj Ci: Los ntawm kev tawg ua thev naus laus zis los hloov hauv ib puag ncig
Hlau 3D Printing tau hloov pauv hauv cov pwm kev lag luam los ntawm "Ib qho chaw hloov chaw" rau "System Innovation":
Ib kauj ruam loj rau tom ntej hauv multi -} cov khoom siv tshuab luam ntawv
Tam sim no, luam tawm cov ntaub ntawv sau zoo li tooj liab txhuas thiab cov hlau ceramic tseem muaj teeb meem hauv kev lag luam. Txawm li cas los xij, cov thev naus laus zis tshiab xws li ntsuab laser thiab ntau kev sib tw nqaj hlau sib tw tau ua qee cov ntaub ntawv sib xws nrog lwm tus. Piv txwv li, cov tuam txhab tuaj nrog tooj liab Steel Bimetallic luam ntawv cov txheej txheem uas siv interfare metallgical bonding kom pom kev sib haum xeeb ntawm kev ua haujlwm kub thiab muaj zog. Txoj hauv kev no zoo rau pwm rau cov kua - txias radiators.
Hom ntawm Additive Composite Raug
Lub hybrid kev sib raug zoo uas ua ke CNC precision machining yog twb muaj lawm. Piv txwv li, thiab tom qab ntawd cov kab ke luam tawm, thiab tom qab ntawd cov kab noj hniav hloov kho, thiab tom qab ntawd cov kab noj hniav tau txhim kho siv tsib- Axis Machining Center. Qhov no siv tau zoo dua ntawm cov qauv kev pab cuam ntawm 3D luam ntawv thiab ua kom paub tseeb tias cov pwm ua tau zoo yog qhov zoo (ra tsawg dua lossis sib npaug nrog 0.8 μm).
Tsim lub tsev ntse thiab tsis sib haum
Cov tuam txhab hauv Asmeskas tab tom ua haujlwm los tsim cov qauv rau cov hlau 3D luam ntawv luam ntawv. Cov qauv no suav nrog cov hmoov ntawm cov hmoov (sphererity ntau dua lossis sib npaug rau 0.5%), muaj peev xwm nrhiav tau (CT Ai algorithms kuj tau siv los txhim kho txoj hauv kev luam tawm tib lub sijhawm. Los ntawm tshuab kev txawj ntse, ib lub platform tau ua kev txhawb nqa qauv 30% sib zog dua thiab luam ntawv 25% txuag tau.
