Cov txheej txheem tsim khoom ntawm PC lampshade

Cov ntaub thaiv teeb yog cov khoom siv ntau heev hauv lub neej txhua hnub. Cov ntaub ntawv siv rau PC cov ntaub thaiv teeb yog cov ntaub ntawv PC / PMMA uas sib kis tau. Peb tuaj yeem ua ob qho tib si ntawm ob yam khoom no. Peb muaj ntau tshaj 17 xyoo ntawm kev paub hauv kev ua pwm thiab muaj ntau tshaj 100 rooj plaub ntawm kev tsim cov ntaub thaiv teeb. Cov hauv qab no yog cov txheej txheem tsim cov ntaub thaiv teeb.

1. Kev tshuaj xyuas qhov xav tau thiab kev tsim qauv digital

Kev ua qauv qhia txog kev ua haujlwm ntawm lub teeb

Kev sim ua lub teeb: Siv LightTools lossis Zemax OpticStudio los tsim kom muaj tus qauv txoj kev teeb kom ntseeg tau tias lub teeb xa tawm ntawm lub lampshade yog ≥92% (cov yam ntxwv ntawm PC khoom) thiab zam kev ci ntsa iab (UGR <19);

Kev txheeb xyuas cov qauv: Siv ANSYS topology los ua kom zoo dua qhov tuab ntawm phab ntsa pwm (ib txwm muaj 1.5-3 hli), sib npaug ntawm qhov sib dua thiab qhov cuam tshuam (muaj peev xwm tiv taus 3kg pob poob).

Tsim 3D ntawm cov pwm

Txoj kev ntaus ntawv: Rau cov chaw nyuaj (xws li Fresnel cov qauv), cov kab ntaus ntawv asymmetric raug saws, ua ke nrog lub tshuab txuas pas nrig peb-seem (angular tolerance ± 0.01 °);

Kev txias txias: Cov hlau 3D luam tawm titanium alloy dej channel (txoj kab uas hla 1.2-2 hli) xyuas kom meej tias qhov kub thiab txias ntawm cov pwm yog ≤ ± 1.5 ℃, tiv thaiv kev ntxhov siab dawb ntawm cov khoom siv PC.

2. Kev ua haujlwm zoo thiab kev kho qhov chaw

Cov thev naus laus zis tseem ceeb:

Cavity milling, tsib-axis ultra-precision tshuab (GF Machining Solutions), qhov roughness ntawm qhov chaw Ra≤0.02μm

Microstructure etching, femtosecond laser + nanoimprint composite txheej txheem, Fresnel tob 0.05mm ± 0.003mm

Kev ua electrode, kev siv hluav taws xob ntawm graphite electrodes (qhov sib txawv ntawm qhov tawm 0.03mm), ntug R lub kaum sab xis ≤0.1mm

Kev kho kom lub ntsej muag muaj zog

Kev txhuam hniav qib optical: Kev txhuam hniav ntau theem nrog pob zeb diamond gypsum (los ntawm W40 txog W0.5), ua ke nrog magnetorheological polishing (MRF) kom tshem tawm kev puas tsuaj rau hauv qab;

Txheej tiv thaiv kev nplaum: Pob zeb diamond-zoo li carbon (DLC) txheej (nrog rau qhov tuab ntawm 2-3μm) txo qhov kev quab yuam demolding rau <5kN thiab txuas lub neej pwm mus rau 800,000 pwm

3. Kev txheeb xyuas pwm sim thiab kev tsim khoom ntau lawm

Qhov rai txheej txheem txhaj tshuaj molding

Kev tswj qhov kub thiab txias: Qhov kub ntawm lub thoob 280-310 ℃ (PC yaj index 18g/10min), qhov kub ntawm pwm 90-110 ℃ (kom tiv thaiv cov khoom khawb txias);

Kab nkhaus siab: Peb theem siab tuav (60MPa → 45MPa → 30MPa), them nyiaj shrinkage 0.6-0.8%.

Kev kho qhov tsis zoo uas kaw-lub voj voog

Cov kab txuas tau tsim thiab qhov chaw ntawm lub rooj vag tsis tsim nyog, ua rau muaj kev sib sau ua ke ntawm ntau qhov dej ntws. Kho lub sijhawm ntawm lub koob valve kub khiav (yuam kev ± 5ms)

Qhov chaw deformation, microstructure collapse ntawm pwm lossis polishing tsis sib xws, kho qhov chaw vuam + ion beam shaping (qhov kho kom raug 0.005mm)

Kev tawg ntawm kev ntxhov siab, qhov nqes hav tsis txaus ntawm kev rhuav tshem (<1°) lossis qhov ceev ntawm kev rhuav tshem sai dhau, nce tus naj npawb ntawm cov koob rhuav tshem (1 rau txhua 100cm²)

4. Cov ntsiab lus tseem ceeb ntawm kev tsim pwm txhaj tshuaj:

Kev ua tau zoo ntawm qhov muag thiab kev tsim qauv

Kev xa hluav taws xob thiab kev tswj hwm txoj kev pom kev

Qhov microstructure ntawm qhov chaw: Nanoscale Fresnel lens tsim (qhov tob raug ± 0.003 hli), ua tiav los ntawm laser etching lossis electroplating txheej txheem, nrog lub teeb scattering Lub kaum sab xis ntawm ≤15 ° thiab zam kev ci ntsa iab (UGR tus nqi yuav tsum yog <16);

Kev sib npaug ntawm phab ntsa tuab: Cov txheej txheem topological optimization (ANSYS Discovery) tau txais yuav los sib npaug ntawm lub teeb transmittance thiab lub zog. Lub phab ntsa tuab yog 1.2-2.5 hli, thiab qhov kam rau siab tau tswj hwm hauv ± 0.05 hli. Cov kab sib cais thiab cov tswv yim demolding

Kev faib ua feem tsis sib xws: Rau cov nplaim nkhaus tsis sib xws (xws li cov teeb pom kev zoo li paj), 3D sliders thiab hydraulic core-rub cov pas nrig txuas tau txais yuav. Lub kaum sab xis ntawm kab sib cais yog ≤0.5 ° kom ntseeg tau tias tsis muaj teeb ci.

Txoj kab nqes ntawm kev rhuav tshem: Txoj kab nqes ntawm qhov chaw pom kev ≥1.5 °, thiab txoj kab nqes ntawm qhov chaw tsis pom kev ≥0.8 °. Lub kaw lus ejection siv silicon nitride ceramic ejection pins (kev sib txhuam coefficient <0.1).

Kev sib koom tes ua kom zoo dua ntawm cov ntaub ntawv thiab cov txheej txheem

Kev xaiv cov hlau pwm

Cov hlau uas ci ntsa iab heev: S136 SUPREME (HRC 52-54) los yog German Gritz 1.2085 ESR (ua kom ci ntsa iab rau Ra 0.008μm) yog qhov zoo dua;

Kev kho mob tiv thaiv xeb: Qhov saum npoo yog coated nrog ib txheej pob zeb diamond-zoo li carbon (DLC) (2-3μm tuab), uas tuaj yeem tiv taus cov pa roj acidic uas tsim los ntawm kev kub siab decomposition ntawm PC.
