A laser drilling method for sheet metal parts

Abstract

The invention provides a sheet metal part laser drilling method. The sheet metal part laser drilling method is composed of a machine tool, a pressing clamp, an alignment device, an upper mold, a lowermold, a laser hole head and a connecting frame are matched to complete operation. According to the sheet metal part laser drilling method, the laser hole head can solve the problem that when an inclined hole is machined, the existing laser hole head is usually exposed in air when the laser hole head works, sparks generated by laser drilling can be splashed to the unmachined area of the sheet metal part, so that the quality of the sheet metal part is influenced, hole scraps generated during laser drilling are always not cleaned in time, and the problem that the smoothness of the sheet metal part and the inner wall of the inclined hole are influenced is solved due to the fact that the generated hole scraps is relatively high in temperature and cannot be cleaned in time and can be blocked after being cooled.

Description

technical field [0001] The invention relates to the field of punching holes in sheet metal parts, in particular to a method for laser punching holes in sheet metal parts. Background technique [0002] Laser drilling technology is the earliest practical laser technology in laser material processing technology. The current laser drilling machine has realized automatic operation, which has improved a level in the drilling effect, and the processing effect is impressive. In the sheet metal workshop, the laser Drilling generally uses pulsed laser, which has a high energy density and a short time. It is especially suitable for processing small holes with a certain angle and thin materials. However, some problems are often encountered when processing inclined holes: [0003] 1. The existing laser hole head is usually exposed to the air when it is working, and the sparks generated by laser drilling will splash on the unprocessed area of ​​the sheet metal part, thus affecting the qua...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a laser drilling method for sheet metal parts, which can solve the problem that the existing laser hole head is usually exposed to the air when working, and the sparks generated by laser drilling will splash on the sheet metal. The unprocessed area of ​​the metal part affects the quality of the sheet metal part. The hole chips generated during laser drilling are often not cleaned in time, and the temperature of the hole chips generated is high. If they are not cleaned in time, they will easily form agglomerates after cooling, resulting in It affects the smoothness of sheet metal parts and the inner wall of inclined holes, etc.
