Technical Field

[0002] Laser cutting machine is a kind of equipment that uses the heat energy of laser beam to achieve cutting. It is mainly used to cut plates into workpieces of desired shapes. Specifically, the laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system, irradiates the surface of the workpiece, makes the workpiece 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. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.
[0003] At present, most of the existing laser cutting machine beams have a relatively simple structure, which can usually only support the displacement of the installed cutting mechanism. During the laser cutting process, smoke and dust will be generated, which will easily drift into the air. Not only will it adhere to the cutting equipment and affect the equipment accuracy, it is more likely to be accidentally inhaled by the operator and affect the health of the personnel. Most of the existing beam structures are unable to recycle the smoke and dust, and personnel are required to continuously operate the device to clean the smoke and dust. For a long time, it will also increase the workload of the personnel and reduce its practicality. Therefore, we propose a laser cutting machine beam structure to solve the above problems.
