Embodiment Construction

[0024] The invention provides a cutting method for two-dimensional laser cutting pipes. The cutting method adopts a two-dimensional cutting head 100. The two-dimensional cutting head means that the cutting head can only move horizontally in the Y direction and vertically in the Z direction, and is always perpendicular to the pipe. Instead of changing the swing angle with the pipe. Through this cutting method, the two-dimensional cutting head can achieve the effect of three-dimensional pendulum cutting, thereby enhancing its own functions and expanding its processing range, meeting the actual production needs and solving the problem of using the two-dimensional cutting head. The disadvantage of limitations.

[0025] see figure 2 and image 3 As shown, the pipe material 200 of the present invention includes pipe materials such as square pipes, rectangular pipes, and round waist pipes.

[0026] In this embodiment, the pipe 200 refers to a square pipe, one end of the pipe 200 ...

Abstract

The invention provides a cutting method for a two-dimensional laser cutting tubular product. The cutting method comprises the following steps: step 1, setting a to-be-cut path of the tubular product and dividing the to-be-cut path into three sections: a first non-edge-shared contour and an edge-shared contour located at one end and a second non-edge-shared contour located at the other end, wherein the edge-shared contour is connected to the first non-edge-shared contour and the second non-edge-shared contour; step 2, cutting the first non-edge-shared contour by using a two-dimensional cutting head; step 3, cutting the second non-edge-shared contour by using the two-dimensional cutting head; and step 4, cutting the edge-shared contour by using the two-dimensional cutting head in a one-cut ring-cutting manner. The cutting method provided by the invention cuts the tubular product by using the two-dimensional cutting head, so that an effect of three-dimensional swing angle cutting can be realized, the function of the two-dimensional cutting head is enhanced and the machining range of the two-dimensional cutting head is expanded, the actual production demand is satisfied, and the shortcoming of using limitation of the two-dimensional cutting head is overcome.

Description

technical field [0001] The invention belongs to the technical field of laser cutting square pipes, rectangular pipes, round waist pipes and other pipe materials, and in particular relates to a cutting method for two-dimensional laser cutting pipe materials. Background technique [0002] When cutting pipes such as square pipes, rectangular pipes, and round pipes, it is assumed that the square pipe 10 is sampled with a two-dimensional laser for cutting, as in figure 1 As shown, the cutting of the material head 11 and the material tail 12 is respectively carried out on the co-edge part of the square pipe 10. This kind of pipe material co-edge cutting, the end of the cut workpiece is not in a horizontal plane, such as figure 1 Region A and Region B are shown. [0003] If it is a weldment for butt joint, the pipe will not be butt joint due to the thickness. Contents of the invention [0004] The purpose of the present invention is to provide a cutting method for two-dimension...
