Abstract

Considering that the non-uniform distribution of the strength in the thick direction will reduce the forming precision during the thick plate bending process, the multi-pass roll forming is an effective process in the production of thick plate. Based on the rebound theory of thick plates, a four-roll roll forming process model was developed. In addition, the multi-pass roll forming control algorithm was established based on the actual roll bending data. The influence of number of rolling bends on the forming quality of the sheet was analyzed qualitatively by numerical simulation. The results indicate that the plastic strain distribution on the surface of the cylinder after the multi-pass roll forming is more uniform, and the rolling bend data multi-pass roll forming control algorithm has strong adaptability, it can not only improve the plate forming quality after multi-pass roll bending, but also can easily realize three-pass roll forming.
