Kudula luso la pamwamba lowala pogwiritsa ntchito laser

Kugwiritsa ntchito makina odulira ulusi wa laser kudula zinthu zowala pamwamba (monga chitsulo chosapanga dzimbiri chowoneka bwino, aluminiyamu yowala kwambiri, mkuwa, mkuwa, ndi zina zotero) kuli ndi kusiyana kwakukulu komanso ubwino waukulu pogwiritsa ntchito laser yachikhalidwe ya CO₂, koma kumafunanso luso lapadera kuti mupeze zotsatira zabwino ndikuwonetsetsa kuti muli otetezeka.

Mfundo yaikulu: Kutalika kwa ulusi wa laser ndi ma microns 1.06, ndipo kuchuluka kwa kuyamwa kwa zinthu zachitsulo ndi kwakukulu kwambiri kuposa kwa CO₂ laser yokhala ndi ma microns 10.6.Izi zikutanthauza kuti laser ya fiber singathe kuwunikira, kugwiritsa ntchito mphamvu moyenera kuli kwakukulu, ndipo chiopsezo cha kuwonongeka kwa kuwunikira kwa zida chimachepa kwambiri. Koma sizikutanthauza kuti palibe zovuta.

Izi ndi njira zodulira pamwamba zowala zomwe zapangidwira makina odulira a laser a fiber:

Ubwino ndi Malo Ofunika Kwambiri

Choyamba, n'zoonekeratu kuti pa chitsulo chosapanga dzimbiri chowala kwambiri cha 304, makina odulira ulusi wa laser wamakono nthawi zambiri amatha kudula mwachindunji popanda kukonza zinthu zovuta monga CO₂ laser, ndipo chiopsezo chowunikira chimakhala chochepa kwambiri. Vuto lalikulu ndi momwe mungapezere malo odulira "opanda cholakwika" kuti mupewe kukanda ndi kusungunuka pamwamba.

Maluso Ofunika ndi Kukonza Ma Parameter

1. Kusankha mpweya ndi kuwongolera kuthamanga kwa mpweya (chofunika kwambiri)

• Kudula kwa nayitrogeni/kuyera kwambiri kwa nayitrogeni
• Cholinga: Kuti pakhale pamwamba powala popanda kusungunuka, kuyera ngati siliva kapena mtundu wachilengedwe.
• Zofunikira pa kupanikizika: Mpweya wokwera kwambiri umafunika (nthawi zambiri> 1.2MPa kapena kupitirira apo). Nayitrogeni wokwera kwambiri amatha kuthamangitsa chitsulo chosungunuka mwachangu, kuti chisawonongeke ndi kusungunuka pamwamba pa chodulira, pomwe chimaziziritsa msoko wodulira.
• Zofunikira pa Kuyera: Gwiritsani ntchito nayitrogeni wa 99.99% kapena kuposerapo kuti mupewe kuipitsidwa ndi mpweya zomwe zimapangitsa kuti pamwamba pake pakhale oxidize ndikukhala wachikasu ndi wakuda.
• Kudula mpweya:
• Zimangogwira ntchito pofufuza liwiro lodulira, ndipo musadandaule ndi malo odulira a black oxide layer. Pa zinthu zogwirira ntchito zomwe zimafunika kukhala ndi mawonekedwe "owala", nthawi zambiri sizigwiritsidwa ntchito.

2. Kusankha nozzle ndi kuwongolera kutalika

• Gwiritsani ntchito mphuno yokhala ndi zigawo ziwiri/zophatikizika: mphuno yokhala ndi zigawo ziwiri (monga HighSpeed, LowSpeed ​​nozzle) imatha kupanga mpweya wokhazikika komanso wophatikizika, mphamvu yochotsera slag ndi yamphamvu, makamaka yoyenera kudula pamwamba pa nayitrogeni yowala kwambiri.
• Kutsegula kwa nozzle: malinga ndi kusankha kwa mbale yokhuthala, nthawi zambiri amagwiritsa ntchito kutsegula kwakukulu pang'ono (monga φ2.0, φ3.0) kuti mpweya uyende bwino.
• Malo olunjika: Yesani kusintha pang'ono pansi (mkati mwa pepala) kuti muchepetse kulunjika kolunjika komanso kosalala.
• Kudula kutalika: sungani kutalika kolondola komanso kokhazikika kuti muwonetsetse kuti mpweya ukuyenda bwino.

3. Kukonza bwino magawo a laser

• Mphamvu: Kugwiritsa ntchito mphamvu zambiri mofulumira kwambiri kungachepetse kutentha komwe kwakhudzidwa ndi kutentha komanso kupewa kusungunuka kwambiri kapena chikasu cha m'mphepete mwachitsulo.
• Kuchuluka kwa ma frequency: Kuchulukitsa ma pulse frequency (monga 500-1000Hz kapena kupitirira apo) kungapangitse kuti mzere wodulira ukhale wofewa komanso wosalala.
• Kuzungulira kwa ntchito: sinthani kuzungulira koyenera kwa ntchito, pansi pa maziko otsimikizira kukhazikika kwa kudula, kuti mupeze magawo abwino kwambiri omalizira.
• Liwiro lodulira: ngati mukufuna kuonetsetsa kuti mwadula bwino, yesani kugwiritsa ntchito liwiro lodulira mwachangu kuti muchepetse kutentha komwe kumasonkhana.

4. Kuyang'anira Kuyang'ana Kwambiri

• Kuyesa koyang'ana kunachitika kuti apeze malo abwino kwambiri owunikira zinthu zowala komanso makulidwe. Nthawi zambiri kuwunikira pang'ono (kuwunikira kwa laser kumakhala mkati mwa mbale) kumathandiza kupeza gawo loyima bwino.

Zoganizira zapadera pazinthu zosiyanasiyana zonyezimira

galasi losapanga dzimbiri:

• Malo oyamba oteteza: kugwiritsa ntchito filimu yapadera yoteteza ya laser yapamwamba kwambiri! Iyi ndiyo njira yothandiza kwambiri yopewera kudontha komwe kumachitika panthawi yodula ndi pamwamba pa tebulo la makina kuti asakanda pamwamba pa galasi.
• Pambuyo podula, filimu yoteteza imatha kung'ambika mosavuta kuti pakhale malo osalala.

Aluminiyamu ndi aluminiyamu (makamaka kuwala kwambiri):

• Kuopsa kwa kuwunikira: Kuwunikira kwa aluminiyamu yoyera ndi aluminiyamu ya silicon yokwera kukadali kwakukulu. Ngakhale kuti chiopsezocho chili chotsika kuposa CO₂, ma laser a fiber amphamvu kwambiri (monga ma watts 10,000 kapena kuposerapo) ayenerabe kukhala maso ndi momwe kuwunikira kumbuyo kungakhudzire zigawo zamkati mwa mutu wa fiber podula.
• Ma Parameters: Aluminiyamu imatulutsa kutentha mwachangu, imafuna mphamvu yayikulu komanso liwiro lachangu. Gwiritsani ntchito nayitrogeni yoyera kwambiri ndipo mungafunike kuwonjezera pang'ono argon kuti mupeze gawo lowala.
• Kupachika zinyalala: Kudula aluminiyamu n'kosavuta kupanga kupochika zinyalala pansi, zomwe ziyenera kuthetsedwa mwa kukonza mphamvu ya mpweya ndi kuyang'ana bwino.

mkuwa ndi mkuwa:

• Kuwunikira kwakukulu: Mkuwa weniweni (mkuwa) ndi chimodzi mwa zitsulo zomwe zimawunikira kwambiri ndipo ndi chiopsezo ku ma laser a ulusi. Nthawi zonse yambani kuyesa ndi mphamvu yochepa.
• Vuto la kuyamwa: Laser wobiriwira wa ulusi (wavelength 515nm) ungagwiritsidwe ntchito. Mkuwa uli ndi mphamvu zambiri zoyamwa kuwala kobiriwira. Ndi chisankho chabwino kwambiri chodulira mkuwa, koma zida zake ndi zodula.
• Mkuwa: zinc, nthunzi ya zinc idzapangidwa podula, gawolo ndi losavuta kulida. Nayitrogeni wopanikizika kwambiri amafunika ndipo magawo ake ndi abwino.

Malangizo a chitetezo ndi kagwiritsidwe ntchito

1. Mayeso oyamba:Pazinthu zowala kwambiri (mkuwa weniweni, aluminiyamu yeniyeni), podula koyamba, zidutswa zingagwiritsidwe ntchito kaye, ndikuyesedwa ndi mphamvu yotsika kuti muwone momwe kudula kulili komanso momwe makina amagwirira ntchito.

2. Kuyang'anira zida:Onetsetsani kuti mutu wa laser wa makina anu odulira laser wa fiber uli ndi chipangizo choteteza kuwunikira (monga chowunikira kumbuyo). Makina ambiri amakono a fiber optic amphamvu apakatikati mpaka okwera kwambiri amakhala ovomerezeka.

3. Kuyeretsa ndi kukonza:

• Tsukani pamwamba pa chinthucho ndi mafuta musanadule.
• Yang'anani ndi kuyeretsa nozzle nthawi zonse ndikuteteza lenzi. Mpweya wothamanga kwambiri ukadulidwa pamwamba kwambiri ungakweze fumbi mosavuta ndikulilumikiza ku lenzi.

4.Kudula koyeserera ndi laibulale ya magawo:Khazikitsani "laibulale yowala yodulira pamwamba" ya zipangizo zosiyanasiyana, makulidwe osiyanasiyana ndi zofunikira zosiyanasiyana pamwamba, ndipo chitani kutsimikizira kudula pang'ono nthawi iliyonse yomwe zinthuzo zasinthidwa.

Mfundo zachidule

Mapeto:Pa ma laser a ulusi, mfundo yaikulu yodulira zinthu zowala pamwamba yasintha kuchoka pa "momwe mungapewere kuwonongeka kwa kuwala" kupita ku "momwe mungakonzere bwino njira yopezera malo odulidwa bwino ndikuteteza mawonekedwe a zinthuzo". Kudzera mu kuphatikiza "kusintha kwabwino kwa chitetezo cha filimu yodula pamwamba ya nayitrogeni yoyera kwambiri", zinthu zogwirira ntchito zowala kwambiri zitha kukonzedwa bwino komanso moyenera.
