Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe production, in particular to a metal pipe laser cutting and clamping device. Background Art

[0002] The material to be cut is irradiated with a high-power density laser beam, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves over the material, the holes continuously form a very narrow slit, completing the cutting of the material. Due to the small laser spot, high energy density and fast cutting speed, laser cutting can achieve better cutting quality. The laser cutting incision is narrow, the two sides of the slit are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts is high; the cut surface is smooth and beautiful, and the surface roughness is only tens of microns. Laser cutting can even be used as the last process, without mechanical processing, and the parts can be used directly.

[0003] The following problems often exist in the process of laser cutting of metal pipes: First, existing pipe laser cutting equipment often processes the opening on the outer wall of the pipe tightly and then cuts it off, and only processes one pipe at a time, so that when the pipe only needs to be cut, the efficiency of laser cutting of a single pipe is too low; Second, since the pipe cutting requires the pipe to rotate, the clamping mechanism of the pipe needs to rotate, but it is difficult to solve how to control multiple rotatable clamping mechanisms for opening during multi-station cutting. In view of this, in-depth research was conducted on the above problems, and this case was created. Utility Model Content
