Yuav ua li cas kom ua tau siab -precision sib dhos tom qab hlau 3D luam ntawv?

1. Kev tsim kho kom zoo: Nres kev sib dhos ua ntej ua ntej lawv tshwm sim.
Dynamic them nyiaj thiab kam rau ua tis
Raws li cov yam ntxwv ntawm cov txheej txheem luam ntawv (piv txwv li, SLM raug ± 0.05mm thiab EBM ± 0.1mm), tawm hauv chav rau kev sib dhos kam rau ua ntawm 3D qauv theem. Piv txwv li, qhov chaw nyob qhov twg lub turbine hniav thiab lub disk ntawm lub dav hlau cav sib ntsib yuav tsum tau khaws cia nyob rau hauv ib tug kam rau ua ntawm ± 0.02 hli. "kab rov tav nthuav dav" muaj nuj nqi tuaj yeem siv los ua kom cov khoom shrinkage thaum luam ntawv (piv txwv li, titanium alloy qhov shrinkage tus nqi yog li 0.8%). VoxelDance Engineering simulation software pab Guangzhou Ruitong Additive Manufacturing Company txhim kho cov nyiaj deformation ntawm kev cog hniav. Qhov no coj lub deformation ntawm lub nplhaib positioning los ntawm 0.3mm mus rau hauv 0.1mm, uas kho qhov teeb meem ntawm kev sib dhos raug.
Standardized interfaces thiab modular tsim
Siv cov kev sib txuas ua ke zoo li USB interface kev sib txuas thiab Lego-style mortise thiab tenon qauv kom ua tau yooj yim sib dhos. Piv txwv li, tus qauv kev sib tw OpenRC F1 muaj cov qauv kev sib txuas uas ua rau nws yooj yim rau cov neeg siv hloov qhov chaw xws li log tsheb thiab tus Tsov tus tw. Rau kev tsim kho nyuaj, lawv tuaj yeem tawg mus rau hauv me me, cais qhov chaw (xws li cov pob qij txha, kev sib txuas, thiab cov plhaub ntawm caj npab neeg hlau) uas tuaj yeem luam tawm thiab muab tso ua ke ntawm nws tus kheej. Qhov no ua rau nws yooj yim dua los kho thiab hloov kho tom qab.
Txhawb kev optimization thiab ntsej muag -down printing splicing
Siv qhov chaw uas yuav tsum tau spliced ​​raws li lub hauv paus luam ntawv, thiab siv lub flatness ntawm thawj txheej kom lub splicing ntau yog. Piv txwv li, thaum luam tawm ob lub voj voog ib nrab- qauv, tig rau hauv tuaj yeem ua rau kev sib tsoo tsis tshua muaj kev cuam tshuam los ntawm txheej txheej. Txo qhov chaw sib cuag nrog lattice los yog conical kev txhawb nqa ua kom yooj yim tshem tawm tom qab. Piv txwv li, cov khoom ua los ntawm 316L stainless hlau siv lub checkerboard scanning txheej txheem thiab contour offset scanning kom lub nto tsis ntxhib, mus ntawm Ra12 μm mus rau Ra3.2 μm.
2. Kev tswj cov txheej txheem: kev tswj kom raug ntawm cov chaw luam ntawv
Optimizing zog ceev
Koj tuaj yeem tswj cov duab ntawm lub pas dej molten los ntawm kev hloov lub zog laser, scanning ceev, thiab txheej thickness. Qhov no tuaj yeem pab tiv thaiv cov teeb meem xws li spheroidization thiab tsis tiav fusion. Piv txwv li, lub zog ceev ntawm titanium alloy Ti6Al4V yuav tsum khaws cia ntawm 60 thiab 120 J / mm³. Yog tias lub zog qis dhau los yog qhov nrawm nrawm dhau, lub zog sib txuas sib txuas yuav tsis muaj zog txaus. If the energy density is too high, it may produce thermal stress cracking.
Ua kom huab cua huv thiab qhov kub zoo
Txhawm rau kom cov hlau tsis muaj oxidizing, siab -purity argon lossis nitrogen gas (nrog qib oxygen tsawg dua 0.1%) yog ntxiv rau txhua kauj ruam. Piv txwv li, preheating lub substrate rau 150-200℃ua ntej luam ntawv AlSi10Mg aluminium alloy pab txo thermal stress thiab nres warping. Tsis tas li ntawd, kev siv ntau-beam sib koom tes scanning thev naus laus zis tuaj yeem nthuav tawm cov cua sov tawm kom sib npaug thiab qis dua qhov kev ntxhov siab.
Saib xyuas online thiab muab cov lus teb rau hauv lub voj kaw
Siv cov ntsuas kub infrared, cov koob yees duab yaj hauv pas dej ua ke, thiab lwm yam sensors kom pom qhov kub thiab txias thiab cov duab ntawm lub pas dej yaj hauv lub sijhawm thaum luam ntawv. Piv txwv li, ib lub tuam txhab siv AI algorithms los saib cov kev hloov pauv ntawm qhov dav ntawm lub pas dej yaj, txiav qhov sib txawv ntawm lub zog laser, thiab qis porosity ntawm 0.5% mus rau tsawg dua 0.1%, uas ua rau kom cov khoom ntom ntom.
3. Tshaj tawm- txheej txheem thev naus laus zis: ua kom lub ntsej muag zoo dua thiab ua kom nws zoo li qub.
Kev kho cua sov tau tshem ntawm kev ntxhov siab hauv cov khoom.
Annealing, zoo li cua sov titanium alloy nyob rau hauv argon ntawm 800℃rau ob teev, tuaj yeem tshem tawm cov seem seem uas tsim tawm thaum luam ntawv thiab nres distortion thaum sib dhos. quenching thiab tempering tuaj yeem siv los ua kom siab - lub zog qhov nyuaj thiab tawv dua. Nickel-raws li siab-kub alloy qhov chaw uas tau kho nrog kub isostatic nias (HIP) yog ib qho piv txwv. Lawv qhov ceev yog yuav luag 100%, thiab lawv lub zog qaug zog tau nce ntau dua 30%.
Precision machining thiab kev kho saum npoo ua los ntawm cov tshuab
CNC machining: Rau qhov chaw ua haujlwm zoo li cov kabmob mating, tawm qhov chaw ntawm 0.1-0.3 hli. Siv tsib -axis txuas CNC tshuab cuab yeej kom ua tiav cov kev cai ntawm 0.02 hli flatness thiab Ra3.2 roughness.
Electrolytic polishing yog txheej txheem uas siv cov txheej txheem electrochemical kom tshem tawm cov pob me me ntawm qhov chaw ntawm aluminium alloy qhov chaw. Qhov no txo ​​qis qhov roughness ntawm Ra6 μ m rau Ra0.2 μ m thiab tsim cov txheej txheem passivation uas ua rau cov khoom tiv thaiv corrosion.
Siv Al ₂ O3 los yog iav hlaws dai rau saum npoo ntawm kev kub ceev, kev kho sandblasting tshem tawm cov hmoov seem thiab ua rau saum npoo zoo ib yam. Piv txwv li, ib lub tuam txhab tshwj xeeb siv sandblasting los kho qhov roughness ntawm 3D - luam tawm titanium alloy implants rau Ra1.6 μm, uas pab cov pob txha hlwb lo rau lawv.
Deformation them nyiaj tsav los ntawm simulation
Koj tuaj yeem siv software xws li VoxelDance Engineering los simulate tag nrho cov txheej txheem luam ntawv, kwv yees li cas cov khoom yuav hloov, thiab ua qauv rau cov nyiaj them. Ib lub tuam txhab tshwj xeeb, piv txwv li, txiav qhov deformation ntawm qhov chaw tom qab simulation hloov ntawm 0.5mm mus rau 0.05mm rau aviation cav roj nozzles thiab ua rau kev sib dhos clearance ntau dua los ntawm 80%.
4. Npaj muab cov khoom sib xyaw ua ke: Ua kom txhua yam yog qhov tseeb tsis tu ncua
Lub platform rau kev sib sau ua ke cov khoom uas muaj zog heev
Siv lub hauv paus siab -rigidity, ib qho kev sib kis thiab kev taw qhia, thiab kev sib xyaw ua ke los txo cov txiaj ntsig ntawm cov khoom siv deformation ntawm kev sib dhos coaxiality. Piv txwv li, nyob rau hauv cov kab sib dhos rau humanoid neeg hlau motors, ib puag ncig adaptation tsim (xws li ua kom qhov kub thiab txias zoo ib yam) yog ua hauj lwm los txiav tawm ntawm tus naj npawb ntawm cov kev ua yuam kev.
Kev sib dhos rau qhov pom kev pom thiab kev tswj xyuas lub zog
Ntxiv rau qhov siab - qhov pom kev ua kom pom tseeb kom pom txoj haujlwm thiab kev taw qhia ntawm cov khoom tseem ceeb xws li stator thiab rotor, thiab ua rau muaj qhov yuam kev thaum sib dhos. Nyob rau tib lub sijhawm, kev sib koom ua ke ntawm kev tswj hwm lub zog raug muab tso rau hauv qhov kawg kom ua kom lub qhov muag ntawm cov kev hloov pauv ntawm lub zog thiab lub zog ntawm lub sijhawm tiag tiag hauv ntau cov lus qhia, ua rau "qhov hloov tau yooj yim" ua tau. Piv txwv li, ib lub tuam txhab ntiav cov cuab yeej tswj xyuas kom lub cev muaj zog sib dhos thiab nias lub zog los ntawm kev hloov ntau dua ± 5N, uas ua rau cov bearings tsis tawg.
Cov lus teb rau hauv lub voj kaw thiab muaj peev xwm taug qab cov ntaub ntawv
Sau cov ntaub ntawv ntawm lub siab, hloov chaw, lub zog, thiab lwm yam hauv lub sijhawm tiag tiag thaum lub sijhawm sib dhos thiab muab piv rau cov txheej txheem predetermined. Lub kaw lus yuav cia li tsa lub tswb lossis ua haujlwm yog tias muaj qee yam yuam kev. Piv txwv li, ib lub tuam txhab ua cov ntaub ntawv sib sau ua ke sib cais rau txhua tus tib neeg cov neeg hlau lub cev muaj zog, muab cov txheej txheem tswj xyuas (SPC) thiab kev ua tau zoo, thiab ua rau cov khoom sib xws zoo dua 99.9%.
5. Cov xwm txheej kev lag luam thiab cov kev xav tau tos ntsoov rau
Teb ntawm aerospace
GE Aviation ntiav SLM thev naus laus zis los luam cov roj nozzles rau LEAP xyaw. Qhov no muab 20 daim rau hauv ib qho, ua rau nws 25% sib dua thiab kav ntev li 5 zaug. Ua tsaug rau kev sib koom ua ke ntawm kev luam ntawv parameter optimization thiab CNC precision machining, nws qhov tseeb sib dhos yog ± 0.01mm.
Field of Medical implants
Johnson&Johnson DePuy Synthes siv 3D luam ntawv titanium alloy acetabular khob kom lub ntsej muag du hauv qab Ra0.8 μ m siv electrolytic polishing. Qhov no, ua ke nrog cov qauv tsim ntxeem tau, ua kom cov pob txha loj hlob los ntawm 40%.
