Yaya Laser Cutter yake Aiki?

.Me yasa ake amfani da laser don yankan?

“LASER”, acronym for Light Amplification by Stimulated Emission of Radiation, ana amfani dashi sosai a kowane fanni na rayuwa, lokacin da ake amfani da Laser akan injin yankan, yana samun injin yankan da sauri, ƙarancin gurɓatacce, ƙarancin amfani, da wani dan karamin zafi ya shafa yankin. A lokaci guda kuma, ƙimar canza wutar lantarki na injin yankan Laser zai iya ninka na na'urar yankan carbon dioxide sau biyu, kuma tsayin hasken fiber Laser ɗin ya kai 1070 nanometers, don haka yana da ƙimar mafi girma na sha, wanda shine. mafi m lokacin yankan bakin ciki karfe faranti. A abũbuwan amfãni daga Laser yankan sanya shi a cikin manyan fasaha ga karfe yankan, wanda aka yadu amfani a machining da kuma masana'antu masana'antu, mafi hankula daga cikinsu akwai sheet karfe yankan, yankan a cikin mota filin, da dai sauransu.

.Yaya na'urar yankan Laser ke aiki?

I. Ƙa'idar sarrafa Laser

Ƙaƙwalwar Laser an mayar da hankali ne zuwa wuri mai haske tare da ƙananan diamita (ƙananan diamita zai iya zama ƙasa da 0.1mm). A cikin yankan Laser, irin wannan katako mai ƙarfi zai wuce ta wani madubi na musamman ko mai lanƙwasa, ya billa ta hanyoyi daban-daban, kuma a ƙarshe ya taru akan abin karfen da za a yanke. Inda tsinken Laser ya yanke, karfen ya narke da sauri, ya yi tururi, ya kau, ko kuma ya kai wurin kunna wuta. Karfe yana yin tururi don samar da ramuka, sannan kuma ana fesa iska mai tsananin gudu ta hanyar bututun ƙarfe coaxial tare da katako. Tare da matsa lamba mai ƙarfi na wannan gas, an cire ƙarfe na ruwa, yana yin tsaga.

Na'urorin yankan Laser suna amfani da na'urorin gani da sarrafa lambobin kwamfuta (CNC) don jagorantar katako ko kayan aiki, yawanci wannan matakin yana amfani da tsarin sarrafa motsi don bin lambar CNC ko G na ƙirar da za a yanke akan kayan, don cimma yanke alamu daban-daban. .

II. Babban hanyoyin sarrafa Laser

1) Laser narke yankan

Laser narkewa yankan ne don amfani da makamashi na Laser katako don zafi da kuma narke karfe abu, sa'an nan kuma fesa matsa mara-oxidizing gas (N2, Air, da dai sauransu) ta cikin bututun ƙarfe coaxial tare da katako, da kuma cire ruwa karfe da taimakon iskar gas mai ƙarfi don samar da yankan kabu.

Ana amfani da yankan narkewar Laser don yanke kayan da ba oxidizing ko karafa masu aiki kamar bakin karfe, titanium, aluminum da gami da su.

2) Laser yankan oxygen

Ka'idar laser oxygen yankan yayi kama da yankan oxyacetylene. Yana amfani da Laser a matsayin tushen preheating da iskar gas mai aiki kamar oxygen a matsayin yankan gas. A gefe guda, gas ɗin da aka fitar yana amsawa tare da karfe, yana haifar da yawan zafin jiki na oxidation. Wannan zafi ya isa ya narke karfe. A daya hannun kuma, narkakkar oxides da narkakkar karfe ana hura su daga yankin da ake yin dauki, wanda ke haifar da yanke a cikin karfen.

Laser yankan oxygen ne yafi amfani da sauƙi oxidized karfe kayan kamar carbon karfe. Hakanan ana iya amfani dashi don sarrafa bakin karfe da sauran kayan aiki, amma sashin baƙar fata ne kuma mara nauyi, kuma farashin ya yi ƙasa da na yankan iskar gas.
