Laser processing device with air blowing protection function and method thereof

Abstract

The invention discloses a laser processing device with an air blowing protection function and a method thereof in the technical field of laser processing device. The laser processing device comprisesa supporting groove, wherein supporting plates are arranged on the left side and the right side of the lower end face of the supporting groove; an annular groove is formed in the bottom end face of aninner cavity of the supporting groove; sliding wheels are uniformly installed in an inner cavity of the annular groove; the upper portions of the outer walls of the sliding wheels are sleeved with connecting bases; the connecting bases are uniformly installed on the lower end face of an installation disc; the upper end of the installation disc penetrates through the upper end face of the inner cavity of the supporting groove to the upper portion; the lower end of the outer ring of the installation disc is fixedly connected with an annular gear; a driving motor is arranged on the left side ofthe inner cavity of the supporting groove; the upper end face of a motor shaft of the driving motor is fixedly connected with a gear; the gear is meshed with the annular gear; and an L-shaped supporting frame is fixedly arranged on the left side of the upper end face of the supporting groove. The laser processing device is simple in structure and convenient to operate, the processing precision iseffectively improved, and the operation types are increased.

Description

technical field [0001] The invention relates to the technical field of laser processing methods, in particular to a laser processing device with an air blowing protection function and a method thereof. Background technique [0002] Laser processing has become a common processing method due to its advantages of high energy, fine kerf, no hard contact, and wide application range. However, in actual processing, the workpiece is generally directly exposed in the air. For metal workpieces , it will inevitably oxidize the processed surface, which not only affects the appearance of the workpiece, but also makes the processing effect worse, which will reduce the absorption rate of the laser, cause bubbles in welding, and welding is not reliable, etc. In order to avoid oxidation, blowing is generally used Protective gas (such as inert gas) is used to reduce or eliminate the impact, but the existing nozzles cannot be adjusted in shape, and cannot quickly cool down the workpiece and re...

[0002] Laser processing has become a common processing method due to its advantages of high energy, fine kerf, no hard contact, and wide application range. However, in actual processing, the workpiece is generally directly exposed in the air. For metal workpieces , it will inevitably oxidize the processed surface, which not only affects the appearance of the workpiece, but also makes the processing effect worse, which will reduce the absorption rate of the laser, cause bubbles in welding, and welding is not reliable, etc. In order to avoid oxidation, blowing is generally used Protective gas (such as inert gas) is used to reduce or eliminate the impact, but the existing nozzles cannot be adjusted in shape, and cannot quickly cool down the workpiece and remove chips on the surface of the workpiece. At the same time, the existing protective gas or air cannot be recovered and recycled. , and the existing thin products cannot be clamped, therefore, we propose a laser processing equipment and method with blowing protection function
