Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a laser cutting device for thin plate sheet metal parts. Background Art

[0002] Thin sheet metal parts refer to metal sheet parts processed by stamping, bending, welding, cutting and other processes. These parts are usually made of metal materials such as stainless steel, aluminum, copper, iron, etc. They have the characteristics of light weight, high strength, corrosion resistance, and easy processing. Thin sheet metal parts are widely used in various fields such as automobiles, electronics, communications, home appliances, aerospace, medical equipment, etc., and are an indispensable and important part of the manufacturing industry.

[0003] During the manufacturing process, thin sheet metal parts need to go through multiple processing steps, including cutting, stamping, bending, welding, grinding, spraying, etc. Among them, laser cutting, as a high-precision and high-efficiency processing method, is widely used in the cutting processing of thin sheet metal parts. Laser cutting can achieve precise cutting of complex shapes and fine patterns, while reducing material waste and processing time, and improving production efficiency and product quality.

[0004] However, current laser cutting devices generally need to fix the thin plate before cutting to improve the cutting stability. However, the current fixing operation requires manual assistance, and manual fixing takes more time, especially when the thin plate needs to be replaced or adjusted frequently, which will significantly reduce production efficiency. At the same time, during the laser cutting process, the laser beam has high temperature and high energy. If the manual fixing operation is improper, it may cause injury to the operator.
