Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and in particular relates to a U-shaped tube laser cutting device. Background Art

[0002] The optical cutting machine is a laser cutting machine. During the cutting process, the light beam is focused into a very small focus by the lens of the cutting head, so that the focus reaches a high power density. The heat input by the light beam far exceeds the heat reflected, conducted or diffused by the material. The material is quickly heated to the melting and vaporization temperature. At the same time, a high-speed airflow blows out the melted and vaporized material from the coaxial or non-coaxial side to form a hole for cutting the material, so that the hole forms a continuous narrow slit, completing the cutting of the material. The square tube is cut into a triangular notch and then bent, which is faster than direct bending.

However, the tube needs to be taken out manually and bent by a machine, which is troublesome, and the cut waste is not convenient to clean.
