Inkqubo yokuvelisa isibane sePC

IiLampshades zizinto ezixhaphakileyo kubomi bemihla ngemihla. Izinto ezisetyenziselwa iiPC lampshades zizinto zePC ezisasazekileyo/izinto zePMMA. Singazenza zombini ezi zinto zimbini. Sinamava angaphezu kweminyaka eli-17 ekwenzeni isikhunta kwaye sinama-lampshades angaphezu kwe-100. Oku kulandelayo yinkqubo yokuvelisa iilampshades.

1. Uhlalutyo lweemfuno kunye noyilo lwedijithali

Imodeli yokusebenza kwe-Optical

Ukulinganisa ukukhanya: Sebenzisa i-LightTools okanye i-Zemax OpticStudio ukuze umisele imodeli yendlela yokukhanya ukuqinisekisa ukuba ukuhanjiswa kokukhanya kwesibane se-lampshade yi-≥92% (iimpawu zezinto zePC) kwaye uphephe ukukhanya okuqaqambileyo (UGR<19);

Ukuqinisekiswa kolwakhiwo: Sebenzisa i-topology ye-ANSYS ukuze ulungise ubukhulu bodonga lwesikhunta (oluqhelekileyo yi-1.5-3mm), ukulinganisela ukukhaphukhaphu kunye nokumelana nempembelelo (olukwaziyo ukumelana nempembelelo yebhola yokuwa eyi-3kg).

Uyilo lwe-3D lwezibumba

Icebo lokuchwetheza: Kwiindawo ezintsonkothileyo (ezifana neepateni zeFresnel), imigca yokuchwetheza engalinganiyo iyasetyenziswa, idityaniswe nendlela yokudibanisa intonga yesilayidi esinemilinganiselo emithathu (ukunyamezelana kwe-angular ±0.01°);

Ukupholisa okucwangcisiweyo: Imijelo yamanzi ye-titanium alloy eprintiweyo ye-3D (ububanzi obuyi-1.2-2mm) iqinisekisa ukuba ubushushu bokubumba buyi-≤±1.5℃, nto leyo ethintela ukumhlophe koxinzelelo lwezinto zePC.

2. Ukulungiswa komatshini kunye nonyango lomphezulu ngokuchanekileyo

Itekhnoloji engundoqo:

Umatshini wokugaya iiCavity, umatshini wokuchaneka kakhulu we-axis ezintlanu (i-GF Machining Solutions), uburhabaxa bomphezulu i-Ra≤0.02μm

Ukukrola isakhiwo esincinci, i-laser ye-femtosecond + inkqubo ye-nanoimprint edibeneyo, ubunzulu beFresnel 0.05mm±0.003mm

Ukucutshungulwa kwee-electrode, ukucutshungulwa kombane kwee-electrode ze-graphite (umsantsa wokukhupha umbane yi-0.03mm), umphetho we-R Angle ≤0.1mm

Unyango lokuqinisa umphezulu

Ukupholisha nge-optical-grade: Ukupholisha nge-multi-stage nge-diamond gypsum (ukusuka kwi-W40 ukuya kwi-W0.5), kudityaniswe nokupholisha nge-magnetorheological (MRF) ukuze kupheliswe umonakalo ongaphantsi komhlaba;

Ukwaleka okunamathelayo: Ukwaleka okufana nedayimani (i-DLC) (enobukhulu obuyi-2-3μm) kunciphisa amandla okukhupha ukuya kwi-<5kN kwaye kwandisa ubomi bokwaleka ukuya kwi-800,000 molds

3. Ukuqinisekiswa kwesilingo sokubumba kunye nokwenza ngcono imveliso ngobuninzi

Ifestile yenkqubo yokubumba ngenaliti

Ulawulo lobushushu: Ubushushu bebhareli 280-310℃ (i-PC melt index 18g/10min), ubushushu bokubumba 90-110℃ (ukuthintela ukukrweleka kwezinto ezibandayo);

Ijika loxinzelelo: Ukubamba uxinzelelo olunezigaba ezintathu (60MPa→45MPa→30MPa), izinga lokunciphisa imbuyekezo yi-0.6-0.8%.

Ukulungiswa kwe-closed-loop egqibeleleyo

Umgca we-weld uyaphuhliswa kwaye indawo yesango ayifanelekanga, nto leyo ebangela ukudibana kwemijelo emininzi. Lungisa ixesha lenaliti yevalvu ye-hot runner (impazamo ±5ms)

Ukuguqulwa kwamabala, ukudilika kwesakhiwo se-microstructure sokubumba okanye ukupholisha okungalinganiyo, ukuwelda kokulungiswa kwendawo + ukubumba umqadi we-ion (ubungakanani bokulungiswa yi-0.005mm)

Ukuqhekeka koxinzelelo, ukuthambeka okunganelanga kokudiliza (<1°) okanye isantya sokudiliza esikhawulezayo kakhulu, kwandisa inani leephini zokudiliza (1 kwi-100cm² nganye)

4. Amanqaku aphambili okuvelisa isikhunta ngenaliti:

Ukusebenza okubonakalayo kunye noyilo lwesakhiwo

Ukuhanjiswa kokukhanya kunye nolawulo lwendlela ebonakalayo

Ulwakhiwo oluphantsi komhlaba: Uyilo lwelensi yeFresnel yeNanoscale (ukuchaneka kobunzulu ±0.003mm), olufezekiswa ngeenkqubo zokugrumba nge-laser okanye nge-electroplating, nge-Angle ekhanyayo ye-≤15° kunye nokuphepha ukukhanya okukhanyayo (ixabiso le-UGR kufuneka libe <16);

Ukufana kobukhulu bodonga: I-algorithm yokwenza ngcono i-topological (i-ANSYS Discovery) iyasetyenziswa ukulinganisela ukuhanjiswa kokukhanya kunye nobunzulu. Ubukhulu bodonga buyi-1.2-2.5mm, kwaye ukunyamezela kulawulwa ngaphakathi kwe-±0.05mm. Imigca yokwahlula kunye namaqhinga okudiliza

Ukwahlulahlula okungalinganiyo: Kwiindawo ezigobileyo ezingalinganiyo (ezifana nezibane ezimile okwepetali), kusetyenziswa izilayidi ze-3D kunye neentonga zokudibanisa ezitsala i-hydraulic core. I-Angle ye-parting line offset yi-≤0.5° ukuqinisekisa ukuba akukho flash.

Ithambeka elidilikayo: Ithambeka lomphezulu obonakalayo ≥1.5°, kunye nethambeka lomphezulu ongabonakaliyo ≥0.8°. Inkqubo yokukhupha isebenzisa iiphini zokukhupha i-silicon nitride ceramic (i-friction coefficient <0.1).

Ukwenziwa ngcono kwezixhobo kunye nenkqubo ngokubambisana

Ukukhethwa kwesinyithi sokubumba

Intsimbi epholishwe kakhulu: I-S136 SUPREME (HRC 52-54) okanye iGerman Gritz 1.2085 ESR (epholishwe ngesipili ukuya kwiRa 0.008μm) iyathandwa;

Unyango olumelana nokugqwala: Umphezulu ugqunywe ngumaleko wekhabhoni efana nedayimani (i-DLC) (ubude obuyi-2-3μm), onokumelana neegesi ze-asidi eziveliswa kukubola kobushushu obuphezulu bePC.

Ukuba ufuna ukwenza ngokwezifiso isibane sePC esifanayo, ungaza kuthi. Singabelana ngemiba emininzi esiyenzileyo, okukuvumela ukuba ubone umgangatho wethu kwaye ufumane amava enkonzo yethu.
