Process of forming mirror-shaped relief plates of folded structure

Abstract

We present a process flow sheet that allows dividing the process of shaping of folded structures into several stages. The formation of the relief is achieved by inverting individual sections of the trapezoidal corrugation to give them a mirror-reflected shape. The process is characterized by narrow zones of bending deformations along the lines of the structure marking and by warping of faces without drawing. The field shaper layout and the relationships for calculating geometric and process parameters are presented.
