Muchina wekucheka weLaser unoshanda sei?

.Nei lasers ichishandiswa pakucheka?

"LASER", izwi rinotsanangura Light Amplification by Stimulated Emission of Radiation, rinoshandiswa zvakanyanya muhupenyu hwese, kana laser ikashandiswa kumuchina wekucheka, inoita muchina wekucheka une kumhanya kwakanyanya, kusvibiswa kwakaderera, zvinhu zvishoma zvinoshandiswa, uye nzvimbo diki inokanganiswa nekupisa. Panguva imwe chete, mwero wekuchinja kwemagetsi wemuchina wekucheka laser unogona kunge wakakwira kaviri kupfuura muchina wekucheka carbon dioxide, uye kureba kwechiedza chefiber laser i1070 nanometers, saka ine mwero wepamusoro wekunyudzwa, izvo zvinobatsira zvakanyanya pakucheka maplate esimbi matete. Zvakanakira zvekucheka laser zvinoita kuti ive tekinoroji inotungamira yekucheka simbi, iyo inoshandiswa zvakanyanya muindasitiri yekugadzira nekugadzira, iyo inonyanya kushandiswa kuchekwa kwesimbi, kucheka mumunda wemotokari, nezvimwewo.

I. Nheyo Yekugadzirisa Laser

Danda relaser rinonangidzirwa panzvimbo ine chiedza chine dhayamita diki kwazvo (dhayamita diki inogona kunge iri pasi pe 0.1mm). Mumusoro wekucheka nelaser, danda rakadaro rine simba guru richapfuura nepagirazi rakakosha kana girazi rakakombama, rosvetuka munzira dzakasiyana, uye pakupedzisira rinoungana pachinhu chesimbi chinofanira kuchekwa. Kana musoro wekucheka nelaser wacheka, simbi inonyunguduka nekukurumidza, inopwanyika, inodzima, kana kusvika panzvimbo yekubatidza. Simbi inopwanyika kuita maburi, uye ipapo mhepo inoyerera nekukurumidza inopfapfaidzwa nepaburi re coaxial nedanda. Nekumanikidzwa kwakasimba kwegasi iri, simbi yemvura inobviswa, zvichiita mipata.

Michina yekucheka nelaser inoshandisa optics uye computer numerally control (CNC) kutungamira danda kana chinhu, kazhinji danho iri rinoshandisa sisitimu yekudzora kufamba kutevedzera CNC kana G code yepateni inofanira kuchekwa pachinhu, kuti ikwanise kucheka mapatani akasiyana.

II. Nzira huru dzekugadzirisa nelaser

1) Kucheka neLaser kunyunguduka

Kucheka neLaser melting kunoreva kushandisa simba relaser beam kupisa nekunyungudutsa simbi, wobva wapfapfaidza gasi risina oxidizing (N2, Air, nezvimwewo) kuburikidza ne nozzle coaxial nedanda, wobvisa simbi yemvura nerubatsiro rwesimba regasi kuti ugadzire musono wekucheka.

Kucheka neLaser melt kunonyanya kushandiswa kucheka zvinhu zvisingaoxidize kana simbi dzinoshanda senge simbi isingasvibi, titanium, aruminiyamu uye alloys dzadzo.

2) Kucheka okisijeni neLaser

Pfungwa yekucheka okisijeni nelaser yakafanana nekucheka oksijeni neoksijeni. Inoshandisa laser senzvimbo yekupisa uye gasi rinoshanda senge oxygen segasi rekucheka. Kune rumwe rutivi, gasi rinoburitswa rinoita zvinoenderana nesimbi, zvichigadzira kupisa kwakawanda kweokisijeni. Kupisa uku kwakakwana kunyungudutsa simbi. Kune rumwe rutivi, maoxide akanyungudutswa nesimbi yakanyungudutswa zvinoburitswa kunze kwenzvimbo ye reaction, zvichiita kuti simbi icheke.

Kucheka okisijeni nelaser kunonyanya kushandiswa pazvinhu zvesimbi zvinogadziriswa nyore nyore zvakaita sesimbi yekabhoni. Inogona zvakare kushandiswa pakugadzira simbi isingatsvedzi nezvimwe zvinhu, asi chikamu chacho chakasviba uye chakakombama, uye mutengo wacho wakaderera pane wekucheka gasi risina simba.
