Selective laser sintering (SLS) 3D tshuab luam ntawv ua rau muaj qhov tshwj xeeb zoo thiab tsim tau zoo thaum qhib lub qhov rooj rau cov qauv kev ua haujlwm siab tsis tuaj yeem nrog kev txhaj tshuaj molding. SLS additive manufacturing kuj tshem tawm lub sij hawm ntev txhuas thiab ua ntej peev ntawm kev txhaj tshuaj molding tooling.
JR tau siv SLS 3D luam ntawv los muab cov neeg siv khoom nrog ntau qhov chaw, xws li shafts, thav duab, cov kav dej tsis sib haum, cov pob khawm nyob, clips, thiab lwm yam. Cia peb qhia peb cov txheej txheem ntau lawm.
3D luam ntawvNcej
Kev sib txhuam, haum thiab cov hmoov tshem tawm yog peb yam hauv kev tsim cov shafts tsim los ntawm SLS. Siv 1 mus rau 2 hli rail ntawm sab zoo li qub (qhov "tsis muaj kev ntxhov siab" sab ntawm lub rooj sib txoos) los tswj kev sib txhuam. Qhov sib txawv ntawm txoj kev tsheb ciav hlau thiab lub qag raj yog khaws cia ntawm 0.3mm. Yog hais tias muaj qhov sib txawv ntawm 2 hli los yog ntau tshaj nyob rau hauv cheeb tsam deb ntawm cov kev taw qhia rail, cov hmoov yuav tau yooj yim thiab huv si tshem tawm los ntawm tshuab compressed cua mus rau hauv cov hmoov tshem tawm inlet nyob rau hauv zoo li qub sab.
Thaum tshem cov hmoov, tshuab compressed cua thaum tig lub ncej kom tshuab cov hmoov tawm ntawm cov ncej kab noj hniav. Raws li ib tug natural bearing khoom, nylon muab ib tug du, tsis muaj kev sib txhuam mechanism rau tsawg-load, tsawg-ceev daim ntaub ntawv. Hauv kev thov ntau dua qhov kev sib txhuam tuaj yeem ua kom sov thiab ua rau hnav, ntxig bearings tuaj yeem txiav txim siab.
3D luam ntawvBaffle - Airflow Management
Txhawm rau tso qhov taw tes los ntawm qhov baffle, elongating lub baffle rau hauv cov duab aerodynamic teardrop yuav txo tau qhov twg turbulence tuaj yeem tsim. Qhov no txhim kho airflow efficiency thiab txo cov suab nrov.
Ib txwm tsim cov baffles nrog maj mam sib sib zog nqus cov ces kaum kom tiv thaiv kev tawg ntawm cov phab ntsa ntawm cov yeeb nkab, tshwj xeeb tshaj yog tias cov khoom siv tau siv nyob rau hauv qhov chaw siab thiab / lossis qhov kub thiab txias.
3D luam ntawvEmbeddedBpob ntseg
Hauv qhov piv txwv no, peb piav qhia qhov kev tso ntawm lub pob zeb ceramic rau hauv qhov zawj (CAD ua qauv raws li cov kab noj hniav ntawm lub ntsej muag A thiab B). Xav tias nws yog ib qho kev sib xyaw hybrid pob khawm mechanism.
Nylon yog ib yam khoom zoo uas tsis muaj kev sib txhuam load-bearing. Txawm li cas los xij, hauv cov ntawv thov uas koj xav tias yuav rov ua haujlwm ntev mus ntev, hloov CAD-modeled pob bearings twb nyob rau hauv qhov chaw nrog ceramic pob bearings (mounted los ntawm lub manhole) tuaj yeem ua rau lub zog ruaj khov thiab du.
Thaum tag nrho cov bearings nyob rau hauv lub grooves, ib tug pin tuaj yeem ruaj ntseg kaw cov grooves.
3D luam ntawvNpog
SLS thev naus laus zis tuaj yeem siv los tsim cov khoom siv "bellows" thaum daim ntawv thov kev sib dhos lossis koom ua haujlwm xav tau qee qhov kev hloov pauv. Nco ntsoov, txawm li cas los xij, cov nylon tsis ua haujlwm zoo hauv cov ntawv thov uas yuav tsum tau rov ua dua, xws li cov hlau thiab hose khau raj hauv cov txheej txheem. Yog li ntawd, nylon yuav tsum tsuas yog txiav txim siab rau cov hauv qab hauv cov ntawv thov nrog qhov tsawg zaus ntawm cyclic dabtsi yog khoov.
Circular bellows ua haujlwm zoo tshaj plaws thaum cov ntsiab lus kev ntxhov siab tensile sib npaug sib npaug thoob plaws ntu. Thaum hloov los ntawm qhov sib npaug mus rau ib qho square hauv qab no, txhua qhov kev txav mus los ntawm qhov sib npaug yuav ua rau muaj kev ntxhov siab. Nyob rau hauv rooj plaub no, ib qho kev sib txawv yuav tsum tau ua: siv cov qauv zoo sib xws rau "Deardorff bellows", uas yog qhov tseem ceeb ntawm kev hloov pauv cov duab plaub sib txuas. Nco ntsoov tias vim lub voj voog me me ntawm cov ces kaum, qhov geometry no muaj kev cuam tshuam ntau dua rau kev ntxhov siab thiab yog li nws pheej ua rau tawg thaum lub voj muaj kev ntxhov siab.

Hexagons yog tshwj xeeb zoo rau SLS thev naus laus zis, tsis yog vim lawv tswj hwm kev ntxhov siab thiab kev ua haujlwm ntawm tes, tab sis kuj vim tias ob peb daim duab peb sab (12) yuav tsum tau ua kom raug sawv cev rau hexagons. Yog tias lub voj voog siv los tsim cov kab sib chaws, cia siab tias yuav muaj qhov loj ntxiv ntawm cov ntaub ntawv loj.
Txawm hais tias qhov hnyav ntawm qhov kawg yuav raug txo qis ntawm cov khoom uas tsis yog-mesh, lub sijhawm tu thiab lub sijhawm kos duab ntawm lub kaw lus tau nce ntxiv txij li lub laser tam sim no contouring thiab sau rau hauv ntau qhov sib txawv.
Raws li nrog cov hollow qhov chaw, tus nqi ntawm cov hmoov tsis siv yog tsis cuam tshuam rau cov khoom siv ntxiv rau kev rov ua dua tshiab. Qhov no yog vim qhov sib thooj rau thermal raug ntawm cov khoom. Qhov tseeb, cov khoom mesh yog kim dua rau kev tsim khoom ntau dua li cov khoom siv vim yog lub sijhawm kos duab ntxiv.
SLS 3D luam ntawv tuaj yeem muab txhua qhov nyuaj, thiab JR muaj cov kws tshaj lij engineering pab pawg uas tuaj yeem muab kev daws teeb meem zoo rau koj. Peb tuaj yeem muab cov kev pabcuam yas thiab hlau 3D luam ntawv, yog tias koj xav tau 3D luam ntawv, thov koj xav tiv tauj peb.
