Automatic optimization design method for hat-shaped steel roll pattern

Abstract

The invention discloses an automatic optimization design method for a hat-shaped steel roll pattern, which belongs to the technical field of cold roll forming and comprises the following steps: S1, determining geometric, forming and physical parameters of hat-shaped steel; s2, optimizing and adjusting the number of forming passes; s3, forming angle springback optimization adjustment is carried out; and S4, establishing a cap-shaped steel roll pattern deep learning model database. According to the method, the optimal forming pass number is searched by limiting a strain threshold value and driving iterative feedback of a simulation result; according to the method, the forming angle of the rolled plate shape is measured, and the rebound angle is considered in the roll pattern design pass of the progressive forming type, so that the forming angle of the rolled cap-shaped steel accurately rebounds to become the target forming angle, and the problems of plate shape defects and cost increase caused by the fact that a cold roll forming scheme is designed by depending on a traditional empirical method are solved.
