Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a corrosion-resistant slag removal device for laser cutting machines. Background Technology

[0002] A laser cutting machine focuses a laser beam emitted from a laser source into a high-power-density beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] In the prior art, Chinese Patent Publication No. CN222740525U discloses an anti-corrosion slag removal device for a laser cutting machine, belonging to the field of laser cutting machine technology. It includes a machine casing with a laser cutting head mounted on top, and further includes: the laser cutting head itself, positioned above the cutting platform; and a slag collection mechanism positioned below the cutting platform for collecting waste slag and exhaust gas generated during the cutting process. The slag collection mechanism includes a slag hopper channel located inside the machine casing, with an anti-corrosion coating on the inner wall of the slag hopper channel, and a slag collection box inside the slag hopper channel. This invention features a simple structure, good corrosion resistance, effectively extending the service life of the equipment, high slag removal efficiency, and reduced waste slag accumulation. Through a filter screen and activated carbon adsorption layer, it effectively filters particulate matter and harmful gases in the exhaust gas, ensuring that the emitted gas meets environmental protection standards.

[0004] However, in actual use, the waste residue contains corrosive liquid, making it difficult to process. As a result, the corrosive liquid on the surface poses a certain safety hazard during the recycling of the waste residue, which is not conducive to direct recycling. Therefore, improvements are needed. Utility Model Content
