Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a steel plate laser cutting device. Background Art

[0002] A high-power density laser beam is used to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the light beam moves on the material, the holes continuously form a very narrow slit to complete the cutting of the material. In the comparative case, the publication number is CN219094050U. The utility model discloses a steel plate laser cutting device in the technical field of laser cutting devices, which includes a machine body and a top seat. A transmission mechanism is installed on the top of the machine body, and the peripheral side of the transmission mechanism is connected with an annular conveyor mesh belt. The surface of the annular conveyor mesh belt is evenly distributed with slag leakage mesh holes. A slag collecting box that cooperates with the slag leakage mesh holes is movably installed inside the machine body. Brackets are fixedly installed on both sides of the machine body, and clamping mechanisms are fixedly installed on the surfaces of the two brackets. The bottom surface of the top seat is fixedly connected to the two brackets. A cutting mechanism is slidably connected between the inner surfaces of the top seat. A screw drive assembly is installed between the inner surfaces of the top seat. The peripheral side of the screw drive assembly is transmission-connected to the cutting mechanism, and a stripping press frame is threadedly connected to the surface of the cutting mechanism. The utility model adds a material pressing mechanism for cutting workpieces on the basis of a traditional steel plate laser cutting device through the design of a stripping pressing frame and a cutting mechanism.
