Theoretical investigation of the effect of the taper angle of the deforming roller on the limiting degrees of deformation in the process of flow forming

Abstract

The conditions for the application of taper angles of deforming rollers are considered in the article, which ensure a steady flow of the flow forming. With the help of the developed engineering technique, analytical and graphical dependences of the boundary values of the deformation degrees on the cone angle of the deforming roller are obtained. The results of the theoretical study are in good agreement with the known experimental data. The developed engineering technique can be used in designing the flow forming on the direct and reverse method, as well as for any process of pressure treatment with a local focus of deformation. © The Authors, published by EDP Sciences, 2018.
