Tsarin samar da inuwar fitilar PC

Inuwar fitila samfura ne da aka fi amfani da su a rayuwar yau da kullun. Kayan da ake amfani da su don inuwar fitilar PC galibi kayan PC ne da aka watsar/PMMA. Za mu iya yin waɗannan kayan guda biyu. Muna da fiye da shekaru 17 na ƙwarewa a yin mold kuma muna da fiye da lokuta 100 na samar da inuwar fitila. Ga tsarin samar da inuwar fitila.

1. Binciken buƙatu da ƙirar dijital

Tsarin kwaikwayon aikin gani

Kwaikwayon Haske: Yi amfani da LightTools ko Zemax OpticStudio don kafa samfurin hanyar haske don tabbatar da cewa watsa hasken fitilar ya kai ≥92% (halayen kayan PC) da kuma guje wa walƙiya (UGR <19);

Tabbatar da Tsarin: Yi amfani da tsarin ANSYS don inganta kauri bangon mold (na al'ada 1.5-3mm), daidaita nauyi mai sauƙi da juriyar tasiri (wanda zai iya jure tasirin ƙwallo mai nauyin kilogiram 3).

Tsarin 3D na molds

Dabarun rubutu: Ga saman da ke da sarkakiya (kamar tsarin Fresnel), ana amfani da layukan rubutu marasa daidaituwa, tare da tsarin sandar zamiya mai girma uku (juriyar kusurwa ±0.01°);

Sanyaya ta al'ada: Tashoshin ruwa na ƙarfe mai ƙarfe 3D da aka buga da ƙarfe (diamita 1.2-2mm) suna tabbatar da cewa canjin zafin jiki na mold ɗin ya kasance ≤±1.5℃, yana hana farin kayan PC.

2. Daidaita injina da kuma maganin farfajiya

Fasaha ta asali:

Niƙa rami, injin madaidaicin axis biyar (GF Machining Solutions), ƙaiƙayin saman Ra≤0.02μm

Ƙirƙirar microstructure, femtosecond laser + nanoimprint composite process, zurfin Fresnel 0.05mm±0.003mm

Sarrafa na'urorin lantarki, sarrafa fitar da wutar lantarki na na'urorin lantarki na graphite (ratawar fitar da wutar lantarki 0.03mm), kusurwar gefen R ≤0.1mm

Maganin ƙarfafa saman

Gyaran gani: Gyaran matakai da yawa tare da gypsum na lu'u-lu'u (daga W40 zuwa W0.5), tare da gyaran magnetorheological (MRF) don kawar da lalacewar ƙasa;

Rufin da ke hana mannewa: Rufin da ke kama da na lu'u-lu'u (wanda ke da kauri na 2-3μm) yana rage ƙarfin rushewa zuwa <5kN kuma yana tsawaita rayuwar mold zuwa molds 800,000.

3. Tabbatar da gwajin mold da inganta samar da taro

Tagar tsarin gyaran allura

Kula da zafin jiki: Zafin ganga 280-310℃ (ƙimar narkewar PC 18g/min 10), zafin mold 90-110℃ (don hana ƙyallen kayan sanyi);

Lanƙwasa matsi: Riƙe matsi mai matakai uku (60MPa→45MPa→30MPa), ƙimar raguwar diyya 0.6-0.8%.

Gyaran madauri mai rufewa

An samar da layin walda kuma matsayin ƙofar bai dace ba, wanda ke haifar da haɗuwar kwararar ruwa da yawa. Daidaita lokacin allurar bawul ɗin mai gudu (kuskure ± 5ms)

Nakasa tabo, rugujewar tsarin ƙwayoyin halitta ko gogewa mara daidaito, walda na gyaran gida + siffanta hasken ion (adadin gyara 0.005mm)

Tsagewar damuwa, rashin gangaren rushewa (<1°) ko saurin rushewa da sauri, ƙara yawan fil ɗin rushewa (1 a kowace 100cm²)

4. Muhimman abubuwan da ake buƙata wajen samar da mold na allura:

Ayyukan gani da tsarin ƙira

Gudanar da haske da kuma sarrafa hanyar gani

Tsarin saman: Tsarin ruwan tabarau na Nanoscale Fresnel (daidaitaccen zurfin ±0.003mm), wanda aka cimma ta hanyar gyaran laser ko hanyoyin lantarki, tare da kusurwar watsa haske na ≤15° da kuma guje wa walƙiya (ƙimar UGR dole ne ta kasance ƙasa da 16);

Daidaito tsakanin kauri bango: An yi amfani da tsarin inganta yanayin ƙasa (ANSYS Discovery) don daidaita watsa haske da ƙarfi. Kauri tsakanin bango shine 1.2-2.5mm, kuma ana sarrafa haƙurin a cikin ±0.05mm. Layukan rabuwa da dabarun rushewa

Rabawa mara daidaituwa: Ga saman da ba su da tsari (kamar inuwar fitila mai siffar fure), ana amfani da madaukai masu siffar 3D da sandunan haɗin hydraulic da ke jan core. Kusurwar layin rabuwar ita ce ≤0.5° don tabbatar da babu walƙiya.

Gangaren Rufewa: Gangaren saman gani ≥1.5°, da kuma gangaren saman da ba na gani ba ≥0.8°. Tsarin fitarwa yana amfani da fil ɗin fitar da iskar silicon nitride (haɓakar friction coefficient <0.1).

Inganta kayan aiki da tsari tare

Zaɓin ƙarfe mai siffar mold

Karfe mai ƙarfi: S136 SUPREME (HRC 52-54) ko German Gritz 1.2085 ESR (wanda aka goge madubi zuwa Ra 0.008μm) an fi so;

Maganin da ke jure wa tsatsa: An shafa saman da wani Layer mai kama da lu'u-lu'u (DLC) (kauri 2-3μm), wanda zai iya tsayayya da iskar gas mai guba da ke fitowa daga lalacewar zafin jiki mai yawa na PC.

Idan kana son keɓance irin wannan hasken fitilar PC, za ka iya zuwa gare mu. Za mu iya raba shari'o'i da yawa da muka yi, wanda zai ba ka damar ganin ingancinmu da kuma jin daɗin hidimarmu.
