Description

Technical Field

[0001] The utility model relates to a stainless steel laser cutting machine with a protective structure, belonging to the technical field of laser cutting machines. Background Art

[0002] Laser cutting machine is to focus the laser light 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. As the relative position of the beam and the workpiece moves, the material is eventually cut, thus achieving the purpose of cutting.

[0003] For example, CN220679719U discloses a stainless steel laser cutting machine with a protective structure. Through the coordinated use of a water tank, a reflux pipe and a water pipe, the workpiece being cut can be cooled during laser cutting to prevent the workpiece from being deformed and affecting the quality due to excessive temperature. In addition, through the coordinated use of a water pump, a storage tank and a filter, waste water can be recycled to reduce the waste of water resources. Although water is sprayed on the workpiece to cool it down for protection during the cutting process, a lot of dust and exhaust gas will be generated during the laser cutting process. If not processed, it will affect the air environment of the workshop. In addition, although the clamping plate can clamp and fix the raw materials, the adjustment range of the clamping plate is small and is not suitable for fixing raw materials of various sizes. Utility Model Content

[0004] The purpose of the utility model is to provide a stainless steel laser cutting machine with a protective structure. By arranging an air collecting hood, a ventilation duct and an induced draft fan, the dust and exhaust gas generated during cutting by the laser cutting machine can be adsorbed. The coarse-pore filter screen, filter cotton and activated carbon filter plate in the ventilation duct can filter out harmful substances in the dust and exhaust gas. The sliding plate and the slider can move freely on the operating table, thereby driving the pressure plate to move its position, facilitating the clamping and fixing of materials of different sizes, and improving the practicability of the pressure plate during use, so as to solve the problems raised in the above-mentioned background technology.
