Water induced laser nozzle anti-sputtering protector

Abstract

An anti-splash protector for the water-guided laser nozzle in order to prevent said nozzle from being burnt out has a base plate fixed to the bottom of water-guided laser nozzle module and a central plate surrounded by said base plate and with a central hole for allowing the micro water column for water-guided laser to pass throught. At slot is between said both plates for preventing water drips from flowing from base plate to central plate.

AI Technical Summary

Problems solved by technology

like figure 1 and figure 2 As shown, the existing water guide laser cutting machine has a serious defect, that is, in the actual operation of the water column micro nozzle 3 of the water guide laser cutting machine, due to being blocked by the part of the workpiece 8 that has not been cut through, the micro water column 4 is splashed back, resulting in Splashes and water vapor are filled below and inside the nozzle protection device 11

A large amount of moisture will inevitably condense on the surface of the nozzle guard 11 (see figure 2 ) to form the backsplash water drop 10, when the backsplash water drop 10 contacts the micro-water column, the micro-water column 4 will be pulled away from the center line, and interfere with the water column waveguide effect, often causing the water column micro-nozzle 3 to break in a very short time Burned by the laser beam 5, at the same time, because the micro water column 4 deviates from the center line, the laser beam is also pulled away, and the processing accuracy is greatly deteriorated

[0003] In addition, the water column micro nozzle is the core component of the water guide laser cutting machine, which is not only expensive, but also has a complicated replacement procedure and is not easy to operate

After the water column micro-nozzle 3 is replaced, it is necessary to calibrate the laser focus and adjust the position, which takes a long time. The seriousness of this problem almost makes the water guide laser cutting machine unable to be used in commercial operation.
