This type of equipment is extremely important in modern manufacturing, especially in sheet metal processing applications that require high precision, high speed and flexibility.

[0003] Existing steel plate laser cutting equipment includes a cutting bed, a moving part, a laser, and a control device. The moving part is arranged on the cutting bed, and the laser is arranged on the moving part. The laser is driven by the moving part to move along the three directions of the X-axis, the Y-axis, and the Z-axis. When cutting the plate, the plate needs to be placed on the cutting bed first, the laser moves to the focusing height, and then the laser moves in the XY axis plane to achieve cutting of the plate.

[0004] The cutting bed in the prior art is provided with a nail plate, through which the workpiece is supported, but the nail teeth of the nail plate in the prior art cannot be adjusted according to the workpiece that needs to be cut. When the cutting part contacts the top of the nail teeth, the objects directly contacting the lower part of the steel plate may hinder the slag and molten metal generated in the cutting process from falling and being discharged smoothly. When these cannot fall normally, they will accumulate at the lower incision of the steel plate, resulting in slag and unevenness on the cutting surface, which may seriously affect the smoothness and verticality of the cutting surface.

[0005] Most of the prior art improves the cutting bed from the perspective of cleaning slag, such as a plate laser cutting device and cutting method with application number: 2024107497555, which discloses a technical solution, including a cutting bed and a laser.

A rotating shaft and a second rotating shaft are both rotatably connected to the cutting bed; the first rotating shaft and the second rotating shaft are driven to rotate synchronously by a rotating drive mechanism; a second supporting member is provided between two adjacent first supporting members; the present invention can effectively clean the slag attached to the supporting part, avoid affecting the flatness of the plate placed due to the slag attached to the supporting part, and improve the actual cutting accuracy; the application can clean the slag on the supporting part in time, but the cleaning is after cutting, and it still cannot solve the problem that the slag and molten metal cannot fall and discharge smoothly, and will accumulate at the lower incision of the steel plate, resulting in slag hanging and unevenness on the cutting surface.
