Tuaj yeem tshaj tawm - kev ua tau zoo txhim kho kev ua haujlwm ntawm cov hlau 3D luam tawm ntu?

1. Kev kho cua sov: Tau tshem ntawm cov flaws thiab ua rau lub koom haum ua haujlwm zoo dua
Thaum hlau 3D luam tawm muaj, sai cua txias tuaj yeem tsim cov kev ntxhov siab, coarsearse, thiab sib xyaw sib cais sab hauv cov khoom siv. Qhov no tuaj yeem yooj yim ua rau cov seem los khoov lossis tawg. Los ntawm kev tswj cov cua sov, insulating, thiab kev kho cua txias, kev kho cua sov tuaj yeem txhim kho cov txiaj ntsig ntawm cov ntaub ntawv.
Kev txo cov anneal tau txais ntawm ib qho kev ntxhov siab uas tau tawm ntawm cov txheej txheem luam ntawv thiab nres cov kev hloov pauv thaum lawv tau siv dua. Tom qab kev nyuaj siab annealing, ge cov dav hlau muaj peev xwm txo qhov txawv txav ntawm 3D luam tawm cov qauv siv nruj rau hauv cov tshuab hluav taws xob ruaj khov hauv cov cav dav hlau.
Kev daws teeb meem kev siv thiab kev ua haujlwm laus: Cov txheej txheem no ua rau muaj zog thiab nruj dua los ntawm kev ua kom muaj kev cuam tshuam dav dav thiab ua kom muaj zog ntxiv. Tom qab ib lub tuam txhab tshwj xeeb siv kev daws teeb meem thiab kev kho mob kev laus, lub zog ntawm 3D {{{{{{{{{{{{{{
Kub iSostatic nias (hip): tau txais cov hws sab hauv thiab microcracks nyob rau hauv cov kub thiab siab, uas ua rau cov khoom ntom ntom yuav luag 100%. Lub zog nkees ntawm lub Airbus A350's titanium alloy saj zawg zog nce los ntawm 450mpa kom tau txais kev kho mob ntxiv rau 20 xyoo dhau los ua lub neej 20-xyoos.
2, nto kev kho mob: ua rau nws nyob ntev thiab ua haujlwm zoo dua
Qhov tseeb ntawm cov npoo ntawm 3D luam tawm ntu yog feem ntau ntawm 5 thiab 10 μm, uas tuaj yeem ua qhov kev ntxhov siab thiab ua kom cov feem tsis tshua muaj zog tiv thaiv kev qaug zog. Cov kev kho deg deg kom zoo ntawm lub cev, tshuaj, lossis cov tswv yim siv tshuab, thaum muab cov haujlwm ntxiv:
NEEG KHO TSHUAB POLISHING: Siv Cov Cuab Yeej Zoo li Cov Lus Siav Thiab Sib Tsoo Yuav Cov Log Tsheb Nkhaus Kom Txum Rau Saum Toj Thiab Nqa Cov Ntxhw Ncav Rau Hauv Qab Ob 0.8 μ m. BMW pab pawg ELGW Mechanically poled the 3D-}}}}} μ m rau ra 6.4 μ m μ m thiab lub neej qaug zog dhau 40%.
Txhaj tshuaj blasting thiab sandblasting: Siv ceev {{txav tau xuab zeb mus ntaus saum npoo thiab tsim cov txheej txheej ntawm compressive kev ntxhov siab uas nres tawm ntawm kis tawm. Tom qab ib lub tuam txhab siv cov club cleening kev kho rau 3D luam titanium alnoy rog rog lub neej mus los ntawm 10 ⁵ mus rau 10 ⁷ mus.
Tshuaj Plating Plating thiab Electroplating: Tso Hlau lossis Alloy Txheej rau ntawm saum npoo kom nws tiv taus kev hnav thiab corrosion. Hauv kev lag luam ntaus ntawv, 3D {{{{{{- sandted chromium alloy dag plated nrog npib tsib xee thiab phosphorus. Qhov no tau nce lawv txoj kev tawm tsam rau ntsev pov tseg corrosion los ntawm 24000 teev, uas ua tau raws li ntev- kev kho mob xav tau.
Anodising: Siv cov txheej txheem electrochemical los tsim cov yeeb yaj kiab oxide nyob saum npoo ntawm txhuas alloy kom nws zoo dua thiab tiv thaiv nws los ntawm kev xeb. Tom qab anodising, lub saum npoo hardness ntawm 3D -}}} luam tawm tsheb ntawm ib lub tuam txhab mus los ntawm ib lub tuam txhab mus ntawm kev khawb kom zoo dua los ntawm tsib zaug.
3. Precision Machining: Tau txais qhov tseeb thiab kev sib xyaw ua haujlwm zoo
Feem ntau, cov khoom luam tawm 3D tau muaj kev pheej hmoo ± 0.07mm, uas ua rau nws nyuaj rau kev xav tau ntawm cov twj paj nruag uas xav tau ± 0.025mm yog qhov tseeb. Siv cov thev naus laus zis xws li CNC thiab hluav taws xob tshem tawm Machining (EDM), kev ntsuas hluav taws xob tuaj yeem txhim kho hauv qab no:
Kev tswj ntawm sab qhov yog: ge addutive manufacturing siv CNC machining los txhim kho cov raug ntawm 3D ± 0.276mm, uas yuav tsum tau muab tso ua ke cov khoom tseem ceeb rau cov cav ntoo.
Ua cov yam ntxwv nyuaj: Electrochemical machining (ECM) siv cov tshuaj elevelfulations kom tawg cov ntaub ntawv. Nws kuj tseem tuaj yeem ua haujlwm ntawm nyias-} walled, sib sib zog nqus kab kab sib sib zog nqus uas nyuaj rau ua nrog lwm cov thev naus laus zis. Siv cov mem tes Electrochemical machining, voxel kev nrhav ua rau cov phab ntsa ntawm 3D {4 4}} rouggine tshuab nqus, los ntawm RA 3.2 μm rau RA 0.4 μm.
Kev sib xyaw ua ke: tshaj tawm {- kev ua tau tuaj yeem ua kom nws ua kom tiav cov ntaub ntawv thiab cov txheej txheem ua ke. Piv txwv li, ib lub tuam txhab siv 3D luam ntawv, CNC Machining, thiab electroplating los ua ke 7 ntsiab rau hauv ib lub gearbox ncej. Qhov tshib qhov hnyav los ntawm 30% thiab tus nqi los ntawm 40%.
4. Kev Lag Luam: Tshaj Tawm {{{1} Taug kev ua rau muaj kev txhim kho loj hauv kev ua tau zoo
Hauv Aerospace teb, tus Airbus A350's titanium alloy hloov tau 3D ua cov luam tawm loj ua rau tau txais cov ntawv pov thawj}
Johnson & Johnson's 3D {{{{-}}} sandalt chromium alloy hip khob rau ntau dua 95% ntawm forged ntu. Muaj ntau dua 100,000 tus neeg uas lawv tau muab tso rau hauv.
Titanium alloy tswj Caj Npab ntawm Tesla Cybertruck siv 3D luam ntawv, quenching thiab tempering, thiab tshuab polishing thev naus laus zis. Qhov no ua rau nws 20% muaj zog thiab 15% sib zog, ua nws tus qauv rau qhov siab- kev ua haujlwm hluav taws xob siab.
