Study elastoplastic bending of a sheet blank of different thickness while rolling

Abstract

The work analyzes the process of rolling the sheet blank to obtain a cylindrical shell of large diameter. The analysis is carried out on the basis of strength calculations of elastoplastic bending of the sheet billet taking into account the springing effect. Springing calculation is carried out on the basis of available ratios of energy of plastic and elastic deformations formed in the material of the sheet blank. Conclusions are drawn and practical recommendations are given, which can be used in the process of adjustment of process parameters of rolling machines.
