Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a slag cleaning device for laser cutting machines. Background Art

[0002] Laser cutting machine is a machine that focuses the laser light emitted from the laser into a high-power dense

[0003] 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

[0004] The coaxial high-pressure gas blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves,

[0005] Finally, the material is cut into a slit, thus achieving the purpose of cutting. Laser cutting uses invisible light to

[0006] The beam replaces the traditional mechanical knife, with high precision, fast cutting, and is not limited to cutting pattern restrictions.

[0007] Automatic typesetting saves materials, has smooth cuts, and has low processing costs. It will gradually improve or replace traditional

[0008] The mechanical part of the laser cutter head does not contact the workpiece and will not

[0009] The surface of the workpiece is scratched. The laser cutting speed is fast and the cut is smooth and flat. Generally, no subsequent processing is required.

[0010] The cutting heat affected zone is small, the plate deformation is small, the cutting seam is narrow (0.1mm~0.3mm), and there is no mechanical stress on the incision.

[0011] No shear burrs; high processing accuracy, good repeatability, no damage to the material surface; CNC programming, processable

[0012] Any plane can be cut into large panels without the need for molds, which is economical and time-saving.

[0013] During laser cutting, the metal of the workpiece after being melted or vaporized by the laser tends to adhere to the workbench and form cutting slag after cooling, especially on the saber-tooth bar that supports the workpiece. The traditional way of cleaning the cutting slag is for workers to use hard objects such as iron rods, hammers and pneumatic picks to knock the cutting slag on the rack. The cutting slag is not cleaned cleanly and the efficiency is low. In addition, the saber-tooth bar is long and thin. During long-term use, the saber-tooth bar is prone to deformation, which affects the detachment of the cutting slag generated during the later cutting of the plate, and easily causes the cut plate to stick to the saber-tooth bar.
