Description

Technical Field

[0002] Laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. Laser cutting machine is a high-precision industrial equipment that uses laser beam for cutting. In order to ensure the safety of operators, the protective structure plays a key role in the design of laser cutting machine. Therefore, a protective structure for laser cutting machine is needed to block sparks, prevent radiation and filter harmful gases.

An electric cabinet is arranged inside one end of the shell, and a storage cabinet is connected to the outer end of the electric cabinet. A hinge is fixed to the surface of one end of the storage cabinet. The cabinet door and the storage cabinet are connected by a pin. The cutting module is arranged above the top of the shell, the scale plate is arranged on the top surface of the shell, and the guide groove is fixed to the inside of the storage cabinet. The utility model can receive the cutting debris falling from the hollow plate in all directions by setting the diameter between the guide groove and the hollow plate, and speed up the time taken for the flow of the cutting debris inside by setting the trumpet-shaped structure of the inner wall, and collect the cutting debris through the collection groove. The laser cutting device is dustproofed by collecting the cutting debris, thereby reducing the influence of the cutting debris on the inside of the cutting device and the cutting object.

[0004] However, the dustproof protection structure for the laser cutting machine has the following disadvantages: when the laser cutting machine is running, it is not convenient to block spark splashing and radiation protection, improve sealing and safety, and it is not convenient to filter exhaust gas and reduce pollution when running.
