Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a multi-head laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. As the relative position of the beam and the workpiece moves, a slit is eventually formed on the material, thereby achieving the purpose of cutting. Multiple lasers emitting lasers form a multi-head laser cutting machine. Compared with the traditional single-head laser cutting machine, it has higher efficiency and stronger production capacity. The multi-head laser cutting machine can cut multiple workpieces at the same time, greatly improving production efficiency and is suitable for mass production.

[0003] During the use of the existing multi-head laser cutting machine, the laser emitted by the laser contacts the surface of the workpiece and vaporizes or melts under the action of high temperature, thereby forming a large number of small solid particles at the cutting point of the workpiece. These debris will fly all over the machine body and adhere to the surface of the operating table, making it difficult for subsequent operators to clean them up. In view of this, the present application proposes a multi-head laser cutting machine. Utility Model Content
