Abstract

The invention provides a workpiece bending method, which comprises the steps that: machining information of a workpiece is obtained, the machining information comprises a target angle, and the target angle is the sum of a first angle and a second angle; the workpiece is bent by the first angle in the first direction; and the workpiece bent by the first angle is bent by the second angle so as to obtain a target workpiece, and the angle of the target workpiece is the target angle. Thus, the workpiece is bent twice, so that the second angle of the second-time bending counteracts the allowance of the first angle of the first-time bending; and therefore, the target workpiece with the target angle is obtained. In the process of bending the workpiece twice, stress generated by bending in the workpiece is counteracted; and therefore, the quality of the workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of metal structure processing, in particular to a workpiece bending method. Background technique [0002] High-strength steel is widely used in all walks of life, especially in the design and manufacture of automobiles. In order to strengthen the stability of the car body structure, ultra-high-strength workpieces are usually required. However, because of its high strength, the internal stress after bending is also large, which causes abnormal bending deformation of the workpiece after bending, which affects the quality of the workpiece. It can be seen that the workpiece after the current bending process has abnormal bending deformation, which leads to poor quality of the workpiece. Contents of the invention [0003] An embodiment of the present invention provides a workpiece bending method to solve the problem of poor quality of the workpiece after bending in the prior art. [0004] An embodiment of the ...
