Chii chinonzi Laser Cutting?

Kucheka neLaser inzira yekucheka nekupisa inoshandisa danda reLaser rine simba guru kuti ripe chiedza pabasa. Izvi zvinoita kuti zvinhu zvakapiswa nemwaranzi zvinyunguduke nekukurumidza, kupwanyika, kudzima, kana kusvika pakupisa. Panguva iyi, mhepo inoyerera nekukurumidza nedanda reLaser inobvisa zvinhu zvakanyungudutswa, nokudaro ichicheka basa.

Kupatsanura uye Hunhu hweKucheka kweLaser

Kucheka neLaser kunogona kukamurwa kuita mhando ina: kucheka neLaser vaporization, kucheka neLaser fusion, kucheka neLaser oxygen, uye kucheka neLaser scribing uye controlled fracture.

Kucheka kweLaser Vaporization

Inoshandisa danda relaser rine simba rakawanda kupisa workpiece, ichikurumidza kukwidza tembiricha yayo kusvika pakufashaira kwechigadzirwa munguva pfupi, zvichiita kuti chinhu chacho chiite utsi hwemvura uye chigadzire utsi hwemvura. Utsi hwemvura hunoburitswa nekukurumidza, zvichiita kuti chinhu chacho chicheke pachinobuda. Sezvo zvinhu zvakawanda zvine utsi hwemvura hwakawanda, kucheka utsi hwelaser kunoda simba rakawanda uye hutsi hwesimba.

Kucheka neLaser Fusion

Mukucheka ne laser fusion, laser inopisa nekunyungudutsa simbi. Gasi risingaoxidizing (rakaita seAr, He, N, nezvimwewo) rinopfurwa nepa nozzle coaxial ne laser beam. Kumanikidzwa kwakanyanya kwegasi kunoburitsa simbi yakanyungudutswa, zvichiita kucheka. Kusiyana nekucheka ne vaporization, nzira iyi haidi vaporization yakazara yezvinhu uye inoshandisa chete 1/10 yesimba rinodiwa pakucheka ne vaporization. Inonyanya kushandiswa pakucheka simbi dzisingaoxidizing kana reactive, kusanganisira stainless steel, titanium, aluminium, uye alloys dzadzo.

Kucheka Okisijeni neLaser

Nheyo yekucheka okisijeni nelaser yakafanana nekucheka oxyacetylene. Laser inoshanda senzvimbo yekupisa yekutanga kupisa, nepo magasi anoshanda (senge oxygen) achishanda segasi rekucheka. Kune rumwe rutivi, gasi rinoputika rinoita serinochekwa nesimbi, zvichikonzera oxidation reaction inoburitsa kupisa kwakawanda kweoxidation. Kune rumwe rutivi, rinobvisa maoxide akanyunguduka uye rinonyunguduka kubva munzvimbo ye reaction, zvichiita kuti simbi icheke. Oxidation reaction panguva yekucheka inogadzira kupisa kwakakosha, saka laser oxygen cutting inongoda hafu yesimba rekucheka fusion, nepo kumhanya kwayo kwekucheka kuchikurumidza kupfuura kwe vaporization ne fusion cutting. Inonyanya kushandiswa kune zvinhu zvesimbi zvinogona kuoxidation senge carbon steel, titanium steel, uye heat-treated steel.

Kunyora neLaser uye Kutyoka Kwakadzorwa

Kunyora neLaser kunoshandisa laser ine simba rakawanda kuti iongorore pamusoro pezvinhu zvakapwanyika, zvichiita kuti mugero mudiki upfuure. Kushandisa simba rakati wandei kunokonzera kuti zvinhu zvakapwanyika zvipwanyikane pamwe chete nemugero. Malaser eQ-switched nemalaser eCO₂ anowanzo shandiswa pakunyora neLaser. Kupwanyika kwakadzorwa kunoshandisa kupararira kwekupisa kwakanyanya kunokonzerwa neLaser grooving kuti kugadzire kushushikana kwekupisa kwenzvimbo muzvinhu zvakapwanyika, zvichiita kuti zvipwanyikane pamwe chete nemugero wakanyorerwa.

Mashandisirwo ekucheka neLaser

Michina yakawanda yekucheka nelaser inoshandiswa kuburikidza nezvirongwa zvekudzora nhamba (NC) kana kuti yakagadzirirwa semarobhoti ekucheka. Senzira yekugadzirisa nemazvo, kucheka nelaser kunogona kucheka zvinhu zvese, kusanganisira kucheka simbi dzakatetepa mu2D kana 3D. Mumunda wezvemuchadenga, tekinoroji yekucheka nelaser inonyanya kushandiswa pakucheka zvinhu zvemuchadenga zvakaita setitanium alloys, aluminum alloys, nickel alloys, chromium alloys, stainless steel, beryllium oxide, composite materials, mapurasitiki, ceramics, uye quartz. Zvikamu zvemuchadenga zvinogadziriswa nelaser cutting zvinosanganisira machubhu emoto einjini, matinji etitanium alloy casings, mafuremu endege, matehwe etitanium alloy, mapapiro emuswe, mapaneru emapapiro emuswe, marotor makuru ehelikopta, uye mataira ekudzivirira kupisa eceramic emuchadenga.
