Laser texturing method for plate welding machine box

Abstract

A laser texturing method for a plate welding machine box belongs to the technical field of material processing engineering, and is high in processing efficiency and short in processing cycle. The laser texturing method includes the steps: firstly, coating a protective layer on the surface of a part; secondly, selecting laser parameters of a laser device according to the thickness of the protective layer, performing parameter test cutting on a process side of the part, judging that the parameters are qualified if the protective layer is completely cut through without exposing base materials, judging that the parameters are unqualified if the protective layer is completely cut through while base materials are exposed and scratched, decreasing laser power and performing test cutting again until finding qualified parameters at the moment, judging that the parameters are unqualified if the protective layer is incompletely cut through, and increasing the laser power and performing test cutting again until finding qualified parameters at the moment; and thirdly, performing formal cutting according to the determined laser parameters in test cutting.

Description

technical field [0001] The invention belongs to the technical field of material processing engineering, in particular to a laser engraving method for a sheet welding casing. Background technique [0002] The surface of the part needs to be coated with a protective layer before laser engraving. The traditional engraving method is to use a pre-designed template (such as figure 1 , figure 2 As shown), use a scratch knife to clearly draw all the contour lines on the protective layer along the limited corrosion area, and the whole process needs to be done manually. Since the processed parts are in the shape of a conical surface, the operator accumulates a large error in the process of engraving and shape shifting; in addition, the processing efficiency of this method is low and the processing cycle is long; at the same time, the accuracy and consistency of the part size cannot be guaranteed. It is difficult to guarantee the accuracy required by the contour line, and a large nu...
