3D tshuab luam ntawv lub zog tsis yog tsuas yog ua tau xwb- nws muaj qhov zoo meej hauv cov xwm txheej tshwj xeeb uas kev tsim khoom ib txwm poob qis. Gears kis tau lub zog los ntawm cov hniav meshing los hloov cov lus tsa suab thiab kho qhov nrawm lossis lub zog. Pa ntau lawm cia siab rau hlau txiav los yog txhaj molding. Kev tsim khoom siv ntxiv tsim cov txheej txheej los ntawm txheej ncaj qha los ntawm cov qauv digital, tshem tawm qhov xav tau pwm lossis cov cuab yeej nyuaj thiab ua rau cov geometries uas yuav tsis yooj yim lossis kim los tsim.
Qhov tseeb nyob ntawm lub tshuab thiab txheej txheem. Ntau lub tshuab kev lag luam ua tiav qhov ntev ntawm qhov ntev ntawm ± 0.1 hli, uas yog txaus rau feem ntau ntawm cov ntawv tsis yog - tseem ceeb. Siab dua - cov txheej txheem kawg xws li SLA lossis SLS tuaj yeem ncav cuag ± 0.05 hli raws li kev tswj xyuas.
Feasibility Foundations
Cov kev ua haujlwm digital tso cai rau kev tswj xyuas meej ntawm cov ntaub ntawv, suab, lub kaum ntse ntse, thiab module. Cov neeg tsim qauv tuaj yeem ua cov ntaub ntawv hniav, ntxiv cov txheej txheem lattice nyob rau hauv lub npoo, los yog tsim tsis yog - qauv geometries (herringbone, asymmetric, los yog kev cai hauv paus fillets) yam tsis muaj nqi ntxiv. Qhov kev hloov pauv no yog qhov laj thawj tseem ceeb uas 3D luam tawm zog ua tiav hauv kev tsim qauv thiab qis - ntim ua haujlwm.
Tsim nyog Application Scenarios
1. Prototyping thiab tsim validation
Thaum lub sij hawm tsim cov khoom lag luam thaum ntxov, cov engineers feem ntau xav tau lub zog ua haujlwm sai sai los kuaj qhov sib kis, meshing zoo, suab nrov, thiab kev thauj khoom . 3D luam ntawv xa cov khoom siv lub cev hauv cov xuab moos lossis hnub tsis yog lub lis piam. Automotive teams, piv txwv li, siv cov ntawv luam tawm los ua kom pom tseeb cov ntsiab lus gearbox ua ntej cog lus rau cov cuab yeej kim. Cov ntaub ntawv kho hniav lossis cov hniav tsis sib xws (tsis yog- tus qauv tsim, muab ob npaug- qauv qauv) thiab cov hollow rims sib sib zog nqus tuaj yeem ua tiav hauv ib qho kev tsim.
2. Tsawg-Load thiab Tsis yog-Kev siv tseem ceeb
Hauv cov neeg siv khoom siv hluav taws xob-smartwatches, cov khoom ua si, me me actuators-torque thiab lub luag haujlwm cycles yog me me. Cov tshuab luam ntawv yas ua tau zoo thiab ua kom hnyav thiab raug nqi tsawg. Kev hloov pauv ib ntus rau cov cuab yeej siv khoom lag luam kuj haum zoo: thaum lub tshuab poob qis thiab OEM iav muaj lub sijhawm ua haujlwm ntev, 3D luam tawm tuaj yeem rov ua haujlwm kom txog thaum cov khoom ruaj khov tuaj txog.
3. Cov khoom siv tshwj xeeb
Engineering plastics qhib kev muaj peev xwm ntxiv. PEEK thiab siab -kub nylons tiv taus qhov kub thiab txias siab tshaj 200℃thiab tiv thaiv ntau yam tshuaj, ua rau lawv muaj txiaj ntsig zoo hauv aerospace, tshuaj ua haujlwm, lossis chaw kho mob. Cov ntaub ntawv yooj yim xws li TPU tsim cov iav uas nqus kev poob siab thiab txo qis kev co- muaj txiaj ntsig hauv cov pob qij txha neeg hlau lossis cov txheej txheem ua raws.
Tiag -cov piv txwv ntiaj teb no txhawb kev siv cov no. Formula Cov tub ntxhais kawm sib tw pab pawg tau xaj kev cai polymer pinions los ntawm kev lag luam 3D luam ntawv cov kev pabcuam thiab tau txais cov haujlwm ua haujlwm tsis pub dhau 72 teev rau saw- tsav tsheb. Tshav dav hlau tua hluav taws- pab pawg pabcuam tau siv cov tshuab luam ntawv los kho dej- cov tshuab phom loj ntawm cov tsheb xwm txheej ceev thaum OEM cov khoom tsis muaj. Cov tsev kawm ntawv luam tawm iav teeb rau kev qhia kev sib kis ntawm ib feem ntawm tus nqi ntawm cov qauv hlau machined.
Kev txiav txim siab tseem ceeb rau kev ua tiav cov iav
Kev tsim kho kom zoo
Kho module, lub kaum sab xis siab, thiab cov hniav thickness tseem tseem ceeb. Hom modules rau luam tawm spur iav muaj li ntawm 0.5 hli mus rau 3 hli. Ntxiv cov hauv paus hniav zoo nkauj thiab, qhov twg ua tau, txhawb cov tav txo qis kev ntxhov siab. Topology optimization los yog honeycomb infill tuaj yeem txiav qhov loj thaum khaws cov hniav kom muaj zog. Cov kev tshawb fawb thiab cov kev sim ua tau zoo qhia tau tias zoo- cov ntawv luam tawm tau zoo tuaj yeem ua tiav 30% lossis ntau dua kev txhim kho hauv lub neej qaug zog piv nrog cov tsis yog- kho kom zoo dua qub ntawm cov khoom qub.
Kev xaiv txheej txheem
FDM (fused deposition modeling) muaj kev nkag tau yooj yim tab sis feem ntau xa ± 0.2 hli raug thiab pom txheej txheej. SLA thiab SLS muab cov kev daws teeb meem zoo dua thiab zoo dua qhov zoo rau siab dua - xav tau qhov tseeb. Print orientation tseem ceeb: kev taw qhia cov hniav kom cov flanks tseem ceeb tsis sib npaug rau cov txheej txheem txhim kho lub zog thiab txo qhov xav tau kev txhawb nqa. Txheej qhov siab ntawm 0.05-0.1 hli txhim kho flank smoothness ntawm tus nqi ntawm lub sijhawm tsim.
Post{0}}Kev ua haujlwm
Nto xov yog feem ntau yuav tsum tau. Sanding, chemical smoothing, lossis media blasting tuaj yeem txo qhov roughness ntawm Ra 6-12 µm mus rau Ra 1.6 µm lossis zoo dua, txo suab nrov thiab hnav. Annealing nylon qhov chaw relieves residual kev nyuaj siab thiab txhim kho qhov ntev stability. Cov iav hlau ua los ntawm binder- dav hlau lossis hmoov- cov txheej txheem txaj yuav xav tau kev kho cua sov lossis kev nkag mus rau qhov ntom ntom thiab lub zog.
Kev txwv kom ceev faj
Lub zog ntawm cov khoom siv yog qhov kev txwv tseem ceeb. Feem ntau cov filaments xws li PLA thiab ABS muaj zog flexural nyob rau hauv 50-80 MPa ntau yam - deb ntawm cov hlau (300-500 MPa lossis siab dua). Txawm tias muaj zog nylons thiab PEEK tseem txwv rau kev ua haujlwm siab -torque lossis siab - kev pabcuam cuam tshuam. Inter-txheej txheej hauv FDM ntxiv kom txo tau lub zog zoo; Cov kev xeem thauj khoom feem ntau qhia cov ntawv luam tawm mus txog 25-35% ntawm cov khoom siv theoretical ntau lub zog.
Kev hnav tsis kam yog lwm qhov kev sib tw. Yas flanks ua kom sov nyob rau hauv zawv zawg sib cuag thiab tuaj yeem hnav sai dua li cov hlau lossis txhaj tshuaj - molded engineering plastics tshwj tsis yog tshwj xeeb qis - cov khoom sib txhuam (piv txwv li, qee cov khoom siv igus) yog siv. Qee qhov kev lag luam tribological filaments tau pom txog li tsib npaug ntawm kev hnav lub neej ntawm tus qauv POM hauv kev sib piv hauv cov khoom nruab nrab.
Dimensional sib xws thoob plaws ntau yam tsim yuav tsum tau calibrated tshuab thiab tswj ib puag ncig. Rau cov khoom ntim ntau tshaj li ntawm 1,000 daim, txhaj tshuaj molding lossis cov pa machining feem ntau ua rau kev lag luam ntau dua.
Cov Piv Txwv Daim Ntawv Thov
Kev Kawm Txuj Ci: Cov tsev kawm qib siab luam tawm cov tsheb ciav hlau ua tiav los ua kom pom qhov sib piv, rov qab, thiab ua haujlwm zoo yam tsis muaj cov hlau kim kim.
Cov cuab yeej kho mob: kho cov iav me me hauv cov pob qij txha pob qij txha lossis cov cuab yeej pabcuam tuaj yeem tsim kho rau tus kheej lub cev.
Kev kos duab thiab kev sib tham sib txuas: cov neeg tsim qauv tsim cov txheej txheem sib txawv, qhov pom kev sib tw iav uas yuav ua rau lub tshuab tsis zoo.
Kev Kho: Cov iav hloov ib ntus lossis xwm txheej ceev kom cov kab ntau lawm khiav thaum cov khoom mus tas li.
