solusyon

Ang sumusunod ay isang buod ng mga solusyon sa mga karaniwang problema ng mga laser cutting machine, na pinagsama sa maraming teknikal na dokumento at praktikal na karanasan sa industriya, na sumasaklaw sa maraming aspeto tulad ng makinarya, optika, elektrikal at pagpapatakbo at pagpapanatili:

 1. Mga problema sa kalidad ng pagputol

1. Patuloy na pagputol o magaspang na paghiwa

 Suriin kung ang setting ng kapangyarihan ng laser ay masyadong mababa, at ayusin ang mga parameter ng kapangyarihan ng potentiometer o software.  

Linisin o palitan ang kontaminado / pagod na focus lens, reflective lens, at tiyaking walang offset ang optical path.  

Ayusin ang focal length sa pinakamagandang posisyon at i-calibrate ito gamit ang Focus Position Test Tool.  

Suriin ang kadalisayan ng auxiliary gas (tulad ng nitrogen o oxygen). Kung hindi sapat ang presyon, kailangan itong iakma sa inirerekomendang halaga.  

2. Cutting size deviation o graphic deformation

I-calibrate ang katumbas ng pulso ng CNC system at ayusin ang mga parameter ng step pitch sa software.  

Suriin kung ang mga turnilyo ng kasabay na gulong ay maluwag, kung ang pag-igting ng sinturon ay angkop, at ikabit ang mga mekanikal na bahagi.  

Kung may nawawalang hakbang sa panahon ng dynamic na pagputol, kinakailangang bawasan ang bilis ng pagproseso o suriin ang katatagan ng motor driver.  

3. Burr o abnormal na spark

Palitan ang nawawalang nozzle at i-optimize ang presyon ng gas (tulad ng nitrogen para sa pagputol ng hindi kinakalawang na asero).  

Suriin ang offset ng posisyon ng focus ng laser at muling i-calibrate ang optical path.  

Para sa mga materyales na may mataas na pagmuni-muni (tulad ng aluminyo, tanso), lumipat sa teknolohiya ng pagbubutas ng pulso o magdagdag ng mga anti-reflective coating.  

 2. Mechanical at electrical failure

1. Abnormal na paggalaw ng makina (paglalakad, natigil)

Suriin ang koneksyon sa ground wire upang maalis ang static na interference.  

Subukan kung nasira ang motor shaft, kung nasira ang synchronous wheel bearing, at palitan ang mga nasirang bahagi sa oras.  

Suriin ang boltahe ng power supply ng driver (karaniwang 24-60V DC), at gumamit ng multimeter upang suriin ang katatagan ng switching power supply.  

2. Laser light exposure o power attenuation

Suriin kung normal ang sistema ng sirkulasyon ng tubig. Kung ang temperatura ng tubig ay lumampas sa 40 ° C, kailangang palitan ang cooling water.  

I-short-circuit ang AIN at + 5V signal test ng laser power supply. Kung may ilaw, ito ay isang potentiometer failure.  

Palitan ang aging laser tube (tulad ng light decay na higit sa 20%) o ang ignition part ng high-voltage line. Karamihan sa mga pagkakamali ay maaaring malutas sa pamamagitan ng pangunahing pagsisiyasat (tulad ng paglilinis ng lens at pagsuri sa power supply), at ang mga kumplikadong problema ay kailangang isama sa manual ng kagamitan at propesyonal na suporta. Maaaring bawasan ng regular na pagpapanatili ang mga biglaang pagkabigo ng 80%. Para sa mga gumagamit sa antas ng enterprise, inirerekumenda na bigyang-pansin ang takbo ng pag-upgrade ng matalinong kagamitan upang mapahusay ang pangmatagalang pagiging mapagkumpitensya. Para sa mas detalyadong mga kaso, mangyaring sumangguni sa fault library ng International Metal Processing Network.
