Description

Technical Field

[0001] The utility model relates to the technical field of accessories for steel plate laser cutting machines, and specifically to a pressing and fixing component of a steel plate laser cutting machine. Background Technique

[0002] A steel plate laser cutting machine is a laser processing device specifically used for cutting steel plates. Its working principle is mainly based on the high energy and high temperature of the laser beam. When the laser beam irradiates the surface of the steel plate, it will quickly heat the local area of the steel plate above the melting point, and then blow away the melted metal through gas to achieve the purpose of cutting; there are many types of steel plate laser cutting machines on the market, and most of the steel plate laser cutting machines are provided with components for pressing and fixing the steel plate. This type of pressing and fixing component generally uses a cylinder or a hydraulic cylinder to work, driving the corresponding downward pressing component to move downward to achieve downward pressing and fixing of the steel plate.

[0003] However, when this type of pressing and fixing component is in use, although it can complete the downward pressing operation, it lacks a component that can limit the left and right sides of the steel plate and cannot perform guiding operations on the steel plate, which will cause position deviation of the steel plate during placement, making the steel plate not accurately placed at the cutting and processing position, affecting the cutting effect, and bringing inconvenience to users. In view of this, we have proposed a pressing and fixing component for a steel plate laser cutting machine. Content of the Utility Model
