Nigute Gukata Laser Bikora?

.Kuki laseri ikoreshwa mugukata?

"LASER", mu magambo ahinnye yerekana urumuri rwa Amplification na Stimulated Emission of Imirasire, ikoreshwa cyane mubice byose, iyo lazeri ikoreshwa kumashini ikata, igera kumashini ikata ifite umuvuduko mwinshi, umwanda muke, udakoreshwa cyane, kandi agace gato gashushe. Muri icyo gihe, igipimo cyo guhinduranya amafoto ya mashini yo gukata lazeri gishobora kuba cyikubye kabiri icyuma gikata karuboni ya dioxyde de carbone, kandi uburebure bwurumuri bwa fibre laser ni nanometero 1070, bityo bukaba bufite igipimo cyinshi cyo kwinjiza, aricyo byiza cyane mugihe ukata ibyuma byoroshye. Ibyiza byo gukata lazeri bituma iba tekinoroji yambere yo gukata ibyuma, ikoreshwa cyane mubikorwa byo gutunganya no gukora inganda, izisanzwe muri zo ni ugukata ibyuma, gukata mumashanyarazi, nibindi.

.Ni gute utema laser ukora?

I. Ihame ryo gutunganya lazeri

Urumuri rwa laser rwibanze ahantu horoheje hamwe na diameter nto cyane (diameter ntarengwa irashobora kuba munsi ya 0.1mm). Mu gukata lazeri, urumuri runini cyane ruzanyura mumurongo wihariye cyangwa indorerwamo igoramye, izunguruka mu byerekezo bitandukanye, hanyuma amaherezo ikusanyirize ku cyuma cyo gutemwa. Aho umutwe wa laser ukata, icyuma gishonga vuba, kigahinduka, kigahinduka, cyangwa kigera aho cyaka. Icyuma kiva mu mwobo kugira ngo kibe umwobo, hanyuma umwuka w’umuvuduko mwinshi uterwa binyuze muri nozzle coaxial hamwe nigiti. Hamwe nigitutu gikomeye cya gaze, icyuma cyamazi gikurwaho, kigakora ibice.

Imashini zikata lazeri zikoresha optique hamwe na mudasobwa igenzura (CNC) kugirango ziyobore urumuri cyangwa ibikoresho, mubisanzwe iyi ntambwe ikoresha sisitemu yo kugenzura ibyerekezo kugirango ikurikirane code ya CNC cyangwa G yerekana ishusho igomba gucibwa kubikoresho, kugirango igere ku guca ibintu bitandukanye. .

II. Uburyo bukuru bwo gutunganya laser

1) Gukata lazeri

Gukata lazeri ni ugukoresha ingufu za lazeri kugirango ushushe kandi ushongeshe ibikoresho byicyuma, hanyuma utere gaz compression idafite okiside (N2, Umuyaga, nibindi) unyuze muri coaxial nozzle hamwe nigiti, hanyuma ukureho icyuma cyamazi hamwe ubufasha bwumuvuduko ukabije wa gaze kugirango ugabanye icyerekezo.

Gukata lazeri gushonga bikoreshwa cyane cyane mugukata ibikoresho bitarimo okiside cyangwa ibyuma bidakora nk'icyuma kitagira umwanda, titanium, aluminium hamwe na alloys.

2) Gukata lazeri

Ihame ryo gukata ogisijeni ya laser isa no gukata oxyacetylene. Ikoresha lazeri nkisoko yo gushyushya hamwe na gaze ikora nka ogisijeni nka gaze ikata. Ku ruhande rumwe, gaze yasohotse ikora nicyuma, ikabyara ubushyuhe bwinshi bwa okiside. Ubu bushyuhe burahagije gushonga icyuma. Ku rundi ruhande, okiside yashongeshejwe hamwe nicyuma gishongeshejwe bisohoka hanze ya reaction, bigatuma habaho gucamo ibyuma.

Gukata lazeri ya ogisijeni ikoreshwa cyane cyane mubyuma bya okiside byoroshye nkibyuma bya karubone. Irashobora kandi gukoreshwa mugutunganya ibyuma bitagira umwanda nibindi bikoresho, ariko igice kirabura kandi kirakabije, kandi ikiguzi kiri munsi yicyicaro cya gaz inert.
