Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a cutting device with high safety in use. Background Art

[0002] Laser cutting is the process of focusing the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Laser cutting replaces the traditional mechanical knife with an invisible beam, and has the advantages of high precision and fast cutting. It will gradually improve or replace traditional metal cutting process equipment.

[0003] However, the prior art still has shortcomings. During operation, the laser cutting in the prior art may sometimes accidentally injure workers, thereby reducing the safety of the laser cutting equipment. In addition, the existing loading plate cannot be moved, and it is inconvenient for workers to take the processed items.
