Description

Technical Field

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

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves across the material, the holes continuously form narrow slits to complete the cutting of the material. Laser cutting replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. Debris will be generated during the cutting process, but the current laser cutting machine does not have a structure to protect the laser cutting head. The debris generated during the cutting process will splash on the laser cutting head and damage the laser cutting head.
