Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting equipment, in particular to laser cutting equipment for metal plates. Background Art

[0002] During the production and processing of parts, some special-shaped metal parts often need to be cut from metal plates. Since traditional saw cutting and grinding wheel cutting can no longer meet the requirements, laser cutting machines are needed at this time. Due to the high mobility of laser cutting machines and their ability to perform three-axis motion, they can cut and blank parts of various shapes on metal plates. Laser cutting uses a high-power density laser beam to irradiate the material to be cut, causing it to quickly heat to the vaporization temperature and evaporate to form holes. As the beam moves across the material, the holes continuously form very narrow slits, completing the cutting of the material.

[0003] However, current metal plate laser cutting machines still require manual work to lift the metal plate onto the operating table when performing laser cutting of metal plates. Due to the heavy weight of the metal plate and the high table top of the laser cutting machine, frequent manual loading will cause a heavy loading burden on the workers, reduce the loading efficiency, and pose a safety hazard. In addition, without the assistance of a crane, when manually lifting the metal plate to the edge of the operating table, the metal plate must be pushed to the cutting position, and the metal plate will rub against the tooth plate of the cutting machine, causing damage to both the metal plate and the laser cutting equipment.

[0004] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content
