Kodi Chodulira Laser Chimagwira Ntchito Bwanji?

.Chifukwa chiyani laser imagwiritsidwa ntchito kudula?

"LASER", chidule cha Light Amplification by Stimulated Emission of Radiation, chimagwiritsidwa ntchito kwambiri m'mbali zonse za moyo, laser ikagwiritsidwa ntchito pamakina odulira, imapeza makina odulira othamanga kwambiri, oipitsa mpweya pang'ono, ogwiritsidwa ntchito pang'ono, komanso malo ochepa omwe amakhudzidwa ndi kutentha. Nthawi yomweyo, kuchuluka kwa kusintha kwa kuwala kwa makina odulira laser kumatha kukhala kokwera kawiri kuposa makina odulira carbon dioxide, ndipo kutalika kwa kuwala kwa fiber laser ndi 1070 nanometers, kotero ili ndi kuchuluka kwa kuyamwa, komwe kumakhala kopindulitsa kwambiri podula mbale zopyapyala zachitsulo. Ubwino wodulira laser umapangitsa kuti ikhale ukadaulo wotsogola wodulira zitsulo, womwe umagwiritsidwa ntchito kwambiri mumakampani opanga makina ndi opanga, omwe nthawi zambiri amagwiritsidwa ntchito kudula zitsulo, kudula m'munda wamagalimoto, ndi zina zotero.

Kodi chodulira cha laser chimagwira ntchito bwanji?

I. Mfundo Yogwiritsira Ntchito Laser

Mtambo wa laser umayikidwa pamalo owala okhala ndi mainchesi ang'onoang'ono kwambiri (mainchesi ochepa akhoza kukhala ochepera 0.1mm). Mu mutu wodula wa laser, mtambo wamphamvu woterewu umadutsa mu lenzi yapadera kapena galasi lopindika, kugwedezeka mbali zosiyanasiyana, ndipo pamapeto pake umasonkhana pa chinthu chachitsulo chomwe chiyenera kudulidwa. Kumene mutu wodula wa laser wadula, chitsulocho chimasungunuka mofulumira, kuphwanyika, kuphulika, kapena kufika pamalo oyatsira moto. Chitsulocho chimaphwanyika kuti chipange mabowo, kenako mpweya wothamanga kwambiri umapopedwa kudzera mu nozzle coaxial ndi mtambowo. Ndi mphamvu yamphamvu ya mpweya uwu, chitsulo chamadzimadzi chimachotsedwa, ndikupanga mipata.

Makina odulira laser amagwiritsa ntchito ma optics ndi computer numerally control (CNC) kutsogolera mtanda kapena zinthu, nthawi zambiri sitepe iyi imagwiritsa ntchito njira yowongolera mayendedwe kuti itsatire CNC kapena G code ya kapangidwe kake komwe kayenera kudulidwa pa chinthucho, kuti ikwaniritse kudula mitundu yosiyanasiyana.

II. Njira zazikulu zogwiritsira ntchito laser

1) Kudula kwa laser kusungunuka

Kudula kwa laser kumagwiritsa ntchito mphamvu ya kuwala kwa laser kutentha ndi kusungunula chitsulocho, kenako kupopera mpweya wosakanizidwa (N2, Air, ndi zina zotero) kudzera mu nozzle coaxial ndi kuwalako, ndikuchotsa chitsulo chamadzimadzi pogwiritsa ntchito mphamvu ya mpweya kuti apange msoko wodula.

Kudula kwa laser kumagwiritsidwa ntchito makamaka kudula zinthu zosapanga oxidizing kapena zitsulo zosinthika monga chitsulo chosapanga dzimbiri, titaniyamu, aluminiyamu ndi zinthu zake zosakaniza.

2) Kudula okosijeni ndi laser

Mfundo yodulira okosijeni pogwiritsa ntchito laser ndi yofanana ndi kudula kwa oxyacetylene. Imagwiritsa ntchito laser ngati gwero lotenthetsera ndi mpweya wogwira ntchito monga okosijeni ngati mpweya wodulira. Kumbali imodzi, mpweya wotuluka umakhudzana ndi chitsulo, ndikupanga kutentha kwakukulu kwa okosijeni. Kutentha kumeneku ndikokwanira kusungunula chitsulocho. Kumbali ina, ma oxide osungunuka ndi chitsulo chosungunuka zimachotsedwa pamalo ochitirapo kanthu, zomwe zimapangitsa kuti chitsulocho chichepe.

Kudula okosijeni pogwiritsa ntchito laser kumagwiritsidwa ntchito makamaka pazinthu zachitsulo zomwe zimasungunuka mosavuta monga chitsulo cha kaboni. Kungagwiritsidwenso ntchito pokonza chitsulo chosapanga dzimbiri ndi zinthu zina, koma gawolo ndi lakuda komanso lopanda mpweya, ndipo mtengo wake ndi wotsika kuposa wodula mpweya wopanda mpweya.
