Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a bevel swing head laser cutting device. Background Technique

[0002] A laser cutting machine emits laser from a laser, and through an optical path system, it is focused into a laser beam with a high power density; the laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the melted or vaporized metal; as the relative position of the beam and the workpiece moves, finally a cut is formed in the material, thus achieving the purpose of cutting.

[0003] When the existing laser cutting machine is in use, there is a lack of a structure for collecting the smoke generated during the cutting of the laser head. When cutting metal parts with a laser, due to high-temperature ablation, a large amount of metal dust and smoke will be generated. These dust and smoke contain tiny metal particles and harmful substances. If exposed to these environments for a long time, it will cause damage to the respiratory system, eyes, etc. of the operator. Therefore, we need to propose a bevel swing head laser cutting device. Content of the Utility Model
