Description

Technical Field

[0001] The invention belongs to the field of metal cutting, and in particular relates to an automatic cutting device and process for metal processing. Background Art

[0002] Metal cutting machines generally refer to metal laser cutting machines. Metal laser cutting machines are laser cutting equipment specially used to cut and process metal materials. With the continuous progress and development of industrial machinery intelligence, the technology of metal laser cutting machines has become more mature. Laser cutting uses a high-power, high-density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and part of the material evaporates to form holes. As the beam moves, the holes continuously form a very narrow slit, thereby completing the cutting of the material.

[0003] When using a laser cutting machine, the material to be cut is placed on a placement seat. Most of the placement seats are long or triangular placement bars with gaps between multiple placement bars. Before the metal material vaporizes, the material will melt first. Under the influence of the environment, such as low temperature, a small part of the material will not vaporize, and it will still fall in the form of molten metal slag. Although most of the melted material will fall into the gap of the placement bar, some of the material will fall on the top of the placement bar. After long-term use, the metal slag will adhere to the placement bar, causing the placement bar to be uneven. When the material to be cut is placed subsequently, the material to be cut will tilt, resulting in a decrease in cutting accuracy, and the friction between the more metal slag and the material to be cut will also increase, making it difficult to load heavier metal materials and more laborious to load them.
