Qhov Muaj Peev Xwm Muaj Peev Xwm Dab Tsi Ntxiv Cov Khoom Siv Ua Haujlwm tuav rau kev cai -Ua, Complex-Suab Cua Kub Platens?

Compromise machined optimization luam tawm
Lub cua sov platen nrog nyuaj sab hauv coolant channel yog feem ntau ua nrog drilling thiab txhaws ntawm ntau lub qhov ncaj los ua ib txoj hauv kev zigzag uas yog qhov kev sib haum xeeb ntau dua li kev ua kom zoo. Additive manufacturing muaj peev xwm ua kom lub platen nrog du, curving raws uas ua raws li cov qauv ntawm cov cua sov ntws ntau precisely, zoo li cov hlab ntsha nyob rau hauv ib lub cev, tsis yog ib tug nruj drilled network.

Qhov kev txav no qhia txog qhov kev hloov pauv tseem ceeb ntawm txoj kev siv cov cuab yeej thermal xav txog, nyob rau hauv uas nws yog cov txheej txheem tsim khoom siv los ua kom haum rau lub hom phiaj thermal tsim, es tsis yog hloov cov geometry kom haum rau cov kev txwv kev tsim khoom.

Additive Manufacturing ua tus Pabcuam rau Thermal Design Freedom
Kev cai cua sov platen txheej txheem hauv kev tsim khoom yog feem ntau raws li kev xaiv laser melting (SLM) lossis qhia lub zog tso nyiaj (DED). Additive manufacturing manufactures hlau Cheebtsam txheej txheej los ntawm cov hmoov los yog hlau feedstock. Kev ua cov ntaub ntawv xws li aluminium alloys thiab cov cuab yeej steels rau hauv cov qauv ntom ntom ntawm cov duab puab sab hauv yog ua tau.

Hauv cov ntsiab lus no, cov cua sov platens tuaj yeem tsim nrog:

Cua sov caij conformal raws tom qab nyuaj deg duab

Thermal gradient-aligned, curved interior cooling channels

Integrated sensor channels rau embedded ntsuas kub;

Sab hauv cov qauv zoo rau kev txo qhov hnyav siv lattices lossis topology

Qhov no ua rau lub platen tsis muaj thermally txwv los ntawm kev txwv ntawm txoj kab ncaj nraim milling.

Xav txog lub platen qhov twg lub rhaub yog molded kom haum nyob ib ncig ntawm ib tug complex 3D kab noj hniav zoo li lub hnab looj tes, siv cov cua sov precisely qhov twg nws yuav tsum tau thiab ua kom thermal huab hwm coj mus rau qhov tsawg kawg nkaus.

Tswj ntawm geometry rau kev txhim kho ntawm thermal kev ua tau zoo
Kev tsim khoom siv ntxiv tso cai rau cov kev sib txuas sab hauv kom haum rau thaj chaw ntawm kev xav tau cua sov, muab qhov sib txawv ntawm qhov kub thiab txias dua li ntawm cov platen nto. Lub thermal tuag aav ib txwm nyob rau hauv ib txwm drilled designs yuav raug txo kom tsawg.

Cov txiaj ntsig tseem ceeb ntawm kev ua haujlwm yog:

Optimized positioning of heat sources for shorter heats-tau lub sij hawm

Txo lub sijhawm txias los ntawm cov kua dej sib haum

Zoo dua saum npoo kub homogeneity rau siab precision txheej txheem

Tsawg zuag qhia tag nrho loj nrog rau hauv lub lattice reinforcing lug

Cov kev nce qib tam sim no cuam tshuam rau lub sijhawm lub voj voog thiab lub zog kev lag luam hauv thermoforming, sib xyaw nias thiab kev ua tiav daim ntawv thov.

Kev saws me nyuam tam sim no thiab kev txwv hauv kev lag luam
Hlau additive manufacturing (SLM) tau nce mus rau lub ntsiab lus uas nws muaj peev xwm tsim tau cov khoom siv ntom ntom ntom ntom. Tab sis tseem muaj qee qhov kev txwv tsis pub siv:

Tom qab-tsim kho cua sov yog xav tau los daws qhov kev ntxhov siab seem

Sealing nto thiab cov kua dej feem ntau yuav tsum tau ua kom tiav

Tus nqi tsim khoom tseem ntau dua li kev siv tshuab ua haujlwm rau cov qauv yooj yim.

Txawm hais tias cov kev txwv no ntxiv cov thev naus laus zis tau siv los tsim cov qauv platens thiab cov khoom siv ntim tsawg. "Lub peev xwm ua geometries uas koj tsis tuaj yeem xyaum lossis zeb yog tus tsav tsheb tseem ceeb rau kev saws me nyuam hauv cov txheej txheem thermal siab heev.

Qhov cuam tshuam rau kev tsim thiab engineering workflow
Kev tsim khoom ntxiv hloov pauv tus qauv tsim ntawm platen los ntawm kev tsim khoom-tsav txheej txheem rau kev simulation- txheej txheem tsav. Hauv qhov chaw digital koj tuaj yeem iterate cov duab sab hauv channel sai sai ua ntej luam tawm. Yog li thermal finite element tsom xam ua qhov tseem ceeb.

Qhov no tso cai:

Kev nrawm nrawm ntawm thermal profiles

Ua ntej- ua kom sov thiab ua kom txias kom zoo

Kev koom ua ke ntawm cov khoom siv ntau yam rau hauv ib qho kev luam tawm

Qhov tshwm sim yog nruj dua kev koom ua ke ntawm thermal engineering thiab mechanical design.

Abstract
Kev tsim khoom siv ntxiv qhib qhov tshiab ntawm kev ywj pheej rau kev tsim cov cua sov platens, muab lub sijhawm los hloov kho cov thermal kev ua tau zoo, thiab tso cai rau kev tsim cov geometries nyuaj sab hauv, uas tsis tuaj yeem ua tau nrog cov pa machining.

Raws li kev luam thev naus laus zis tau nce zuj zus, cov cuab yeej siv hluav taws xob tau txav mus rau ntau dua thiab ntau dua rau cov qauv tsim, ua haujlwm - cov khoom siv tau zoo. Tseeb tiag, machining txuj ci tsis yog tib yam uas txhais tau tias yav tom ntej ntawm cov cua sov platens. Cov txheej txheem tsim khoom ntxiv tso cai rau kev tsim cov txheej txheem thermal nrog qhov tsis tau pom dua ua ntej.
