Abstract

The invention relates to the technical field of tube cutting, in particular to a tube curvature compensation method. A curved tube is clamped before compensation and rotated around a rotating shaft, the rotating shaft is a horizontal shaft passing through the center of a clamping position, and the curved tube comprises four detection surfaces. The method includes the first step of conducting curvature detection on the curved tube, the second step of calculating the curvature of the curved tube according to the height obtained through detection, and the third step of conducting curvature compensation according to the curvature obtained through calculation. The curvature of the curved tube is detected and the position relation of the cutting surface and a cutting head of the curved tube is adjusted according to a detection result, so that the demands for processing production are met, it is guaranteed that cut contour position precision is within a reasonable error range, and the percent of pass of processing production is increased; laser cutting universality is higher, and cost and conditions for selective purchasing, carrying and storing of tubes are reduced.

Description

technical field [0001] The invention relates to the technical field of pipe cutting, in particular to a pipe curvature compensation method and a laser cutting device. Background technique [0002] When cutting and processing curved pipes, especially curved pipes such as square pipes, rectangular pipes and waist round pipes, it is generally necessary to perform curvature compensation operations (that is, to adjust the positional relationship between the cutting surface of the curved pipe and the cutting head so that the two are in the same shape. preset angle). If the compensation operation is not performed in time, it is easy to cause the cut contour to deviate from the pre-programmed position, resulting in the deviation of the center position of the cutting contour, reducing the pass rate of processing and production, and even damaging the cutting head. [0003] In order to solve the above problems, manual and mechanical auxiliary methods are generally used to perform the ...
