Description

[0001] The invention belongs to the technical field of sheet metal bending processing, and in particular relates to equipment and a processing method for follow-up bending of a sheet metal flexible processing robot. Background Art

[0002] A bending machine is a machine that bends thin plates. It is a commonly used processing equipment for sheet metal workpieces, and the quality of the bending machine has a particularly important impact on the quality of sheet metal bending processing.

[0003] Since the bending length of the bending machine is limited each time, when processing thin iron plates whose length far exceeds the bending area of ​​the bending machine, it is necessary to perform segmented bending because the bending process cannot be completed in one go. However, this bending method has certain problems. The thin iron plates in the area that has been bent are prone to large deviations in the bending angle due to their own metal properties and stress rebound. Therefore, the segmented bending method has poor stability. After the overall bending, the bending angles of the segments may be different, which seriously affects the bending quality of such workpieces. To this end, we propose a sheet metal flexible processing robot follow-up bending equipment and processing method to solve the above problems. Summary of the invention
