Description

Technical Field

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

[0002] Steel plate is a flat steel material made by pouring molten steel and pressing it after cooling. It is flat and rectangular and can be directly rolled or cut from a wide steel strip. Steel plates are divided by thickness: thin steel plates are less than 4 mm, medium and thick steel plates are 4 to 60 mm, and extra thick steel plates are 60 to 115 mm. Steel plates are divided into hot rolling and cold rolling according to rolling. At present, people usually cut circular steel plates by manually placing the circular steel plates on the circular hole template, and then manually holding a cutting knife to cut them. This cutting requires manual cutting action all the time, which is inefficient and cannot be controlled to be the same every time. Laser cutting machines are usually used for cutting. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece. Laser cutting is one of the thermal cutting methods, and most general laser cutting equipment cannot adjust the size of the circular steel plate cutting.

[0003] When existing equipment performs cutting operations on circular steel plates, it usually cuts at fixed sizes or requires multiple adjustments to the cutting size. The operation is cumbersome, the cutting size cannot be easily adjusted, and it is not convenient for the equipment to cut circular steel plates of different diameters. In addition, the workpiece is prone to shifting, which reduces the accuracy of the equipment's cutting of the workpiece, affecting the efficiency and practicality of the equipment's cutting operation on the workpiece.
