Description

Technical Field

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

[0002] Laser cutting machine refers to a device that focuses the laser emitted from a laser into a high-power density laser beam through an optical path system, moves the laser beam and irradiates the surface of the workpiece, uses the thermal energy of the laser beam to make the workpiece reach its melting point or boiling point, and at the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal, eventually forming a slit on the workpiece, thereby achieving the purpose of cutting.

[0003] According to the Chinese patent publication number CN 217799662 U, an adjustable steel laser cutting device is disclosed, including a workbench, a mobile gantry, a top column, and a laser cutting device. The upper end surface of the workbench is provided with a mounting groove. When the device is used, the steel bearing part of the workbench is replaced by a top column that can be raised and lowered, and the top column located below the cutting track is sunk into a laser absorbing liquid according to the cutting track of the laser cutting device. The laser absorbing liquid absorbs the laser beam of the laser cutting device that cuts and penetrates the steel, thereby preventing the cutting table surface composed of the workbench and the top column from being damaged by the laser beam of the laser cutting device, thereby effectively extending the service life of the cutting table surface of the device.

[0004] However, during the laser cutting process, the laser cutting device will generate a lot of heat at the cutting site, which makes the steel easily deformed, and will also produce steel debris at the cutting site. The steel debris will cause splashing and cause harm to the workers. At the same time, the laser cutting device is not convenient for fixing the steel. During the cutting process, the steel may shift in position, affecting the cutting effect. For this reason, we propose a steel laser cutting device. Utility Model Content
