Maitiro ekugadzira rambi rePC

Marambi emwenje zvinhu zvakajairika muhupenyu hwezuva nezuva. Zvinhu zvinoshandiswa pakugadzira marambi emwenje ePC zvinhu zvePC /PMMA zvakapararira. Tinogona kugadzira zvinhu zviviri izvi. Tine ruzivo rwemakore anopfuura 17 mukugadzira chakuvhuvhu uye tine mabhokisi anopfuura 100 ekugadzira marambi emwenje. Inotevera ndiyo nzira yekugadzira marambi emwenje.

1. Kuongorora zvinodiwa uye dhizaini yedhijitari

Kuenzanisa mashandiro ekuona

Kutevedzera chiedza: Shandisa LightTools kana Zemax OpticStudio kuti ugadzire muenzaniso wenzira yechiedza kuti uve nechokwadi chekuti kufambiswa kwechiedza chemumvuri werambi kuri ≥92% (hunhu hwezvinhu zvePC) uye kudzivirira kupenya (UGR<19);

Kusimbiswa kwechimiro: Shandisa ANSYS topology kuti unyatsoona ukobvu hwemadziro emould (akajairika 1.5-3mm), uchienzanisa kureruka uye kuramba kusimba (kunokwanisa kutsungirira 3kg drop ball irritation).

Dhizaini ye3D yemafuru

Maitiro ekunyora: Kune nzvimbo dzakaoma (dzakadai seFresnel patterns), mitsetse yekunyora isina kuenzana inoshandiswa, yakabatanidzwa netambo yekubatanidza tsvimbo ine mativi matatu (angular tolerance ±0.01°);

Kutonhodza kwakagadzikana: Nzira dzemvura dzesimbi dzakadhindwa nesimbi dze3D titanium alloy (dhayamita 1.2-2mm) dzinoita kuti tembiricha yemould ishanduke-shanduke iri ≤±1.5℃, zvichidzivirira kuchena kwezvinhu zvePC.

2. Kugadzira nemazvo uye kugadzirisa pamusoro pechinhu nemazvo

Tekinoroji huru:

Muchina wekugaya maburi, muchina wekugadzira machira une mativi mashanu (GF Machining Solutions), kuomarara kwenzvimbo Ra≤0.02μm

Kucheka kwechimiro chidiki, laser ye femtosecond + nanoimprint composite process, Fresnel depth 0.05mm±0.003mm

Kugadziriswa kwemaerekitirodhi, kugadzwa kwemaerekitirodhi egrafiti nemagetsi (gap rekubuda kwemagetsi 0.03mm), edge R Angle ≤0.1mm

Kurapa kwekusimbisa pamusoro

Kupukuta kweOptical-grade: Kupukuta kwematanho akawanda nedhaimani gypsum (kubva paW40 kusvika paW0.5), pamwe chete nemagnetorheological polishing (MRF) kubvisa kukuvara kwepasi pevhu;

Kuvhara kunodzivirira kunamira: Kuvhara kwakaita sedhaimani (DLC) (kune ukobvu hwe2-3μm) kunoderedza simba rekubvisa simba kusvika <5kN uye kunoita kuti hupenyu hwechiumbwa huve kusvika ku800,000 molds.

3. Kuongororwa kwemusanganiswa wevhu uye kugadziriswa kwekugadzirwa kwehuwandu

Jekiseni Kuumba hwindo

Kudzora tembiricha: Tembiricha yemubhara 280-310℃ (PC melt index 18g/10min), tembiricha yeforoma 90-110℃ (kudzivirira kukwenya kwezvinhu zvinotonhora);

Kudzvanywa kwemuchina: Kubata kudzvanywa kwematanho matatu (60MPa→45MPa→30MPa), mwero wekuderedzwa kwemuchina wekubhadhara 0.6-0.8%.

Kugadzirisa kwakakwana kwezvipingamupinyi

Tambo yekuwedera inogadzirwa uye nzvimbo yegedhi haina musoro, zvichikonzera kusangana kwekuyerera kwakawanda. Gadzirisa nguva yetsono yevharuvhu inopisa (chikanganiso ±5ms)

Kushanduka kwemavara, kudonha kwechimiro chidiki kana kukwesha kusina kuenzana, welding yekugadzirisa yemuno + ion beam shaping (huwandu hwekugadziriswa 0.005mm)

Kutsemuka kwesimba, kusakwana kwekutsvedza kwedhibhiri (<1°) kana kumhanya kwekutsvedza kwedhibhiriri nekukurumidza, wedzera huwandu hwemapini ekutsvedza (1 pa 100cm²)

4. Pfungwa huru dzekugadzira furu yejekiseni:

Kushanda kwemaziso uye dhizaini yemaumbirwo

Kutumira chiedza uye kudzora nzira yemaziso

Maumbirwo epamusoro pechinhu: Dhizaini yelenzi yeFresnel yeNanoscale (kunyatsojeka kwehupamhi ±0.003mm), inogoneka kuburikidza nemaitiro ekucheka nelaser kana electroplating, neAngle inopararira zvishoma ye ≤15° uye kudzivirira kupenya (UGR kukosha kunofanira kuva <16);

Kufanana kweukobvu hwemadziro: Iyo topological optimization algorithm (ANSYS Discovery) inoshandiswa kuyera kufambiswa kwechiedza nekusimba kwacho. Ukobvu hwemadziro i1.2-2.5mm, uye kushivirira kunodzorwa mukati me ±0.05mm. Mitsetse yekuparadzanisa uye nzira dzekuparadzanisa.

Kupatsanurana kusina kuenzana: Kune nzvimbo dzakakombama dzisina kuenzana (dzakadai semarambi ane chimiro chepetal), maslider e3D uye ma hydraulic core-pulling connecting rods anoshandiswa. Angle yekubvisa tambo iri ≤0.5° kuti ive nechokwadi chekuti hapana flash.

Kudzikira kwemvura: Kudzikira kwemvura pamusoro pechiedza ≥1.5°, uye kudzikira kwemvura pamusoro pechiedza ≥0.8°. Sisitimu yekubuda kwemvura inoshandisa silicon nitride ceramic ejection pins (friction coefficient <0.1).

Kushanda pamwe chete kwekugadzirisa zvinhu uye maitiro

Kusarudzwa kwesimbi yemuforoma

Simbi yakakweshwa zvakanyanya: S136 SUPREME (HRC 52-54) kana German Gritz 1.2085 ESR (yakagadzirwa negirazi kusvika Ra 0.008μm) ndiyo inonyanya kufarirwa;

Kurapwa kusingaparari ngura: Pamusoro payo pakafukidzwa nedhaimani rakaita sekabhoni (DLC) layer (2-3μm scoop), iro rinogona kuramba magasi ane acidic anokonzerwa nekuora kwePC pakupisa kwakanyanya.

Kana uchida kugadzirisa rambi rePC rakafanana, unogona kuuya kwatiri. Tinogona kugovera mabhokisi akawanda atakaita, zvichikubvumidza kuti uone hunhu hwedu uye unzwe sevhisi yedu.
