Stress of drawing solid rectangular profiles

В. Н. Трофимов, Tatyana V. Kuznetsova

Abstract

The process of drawing rectangular sections is conveniently designed with the use of analytical expressions that make it possible to operatively evaluate different manufacturing factors. The application of a drawing tool with optimum angles makes it possible to cut down power inputs and reduce the failure and unsoundness of a blank. A design procedure for the drawing stress of the rectangular section is advanced. Formulas for calculating the drawing stress and determining the optimum angles of a channel of the drawing tool are derived. It is shown that the optimum angles depend on the friction coefficient and the reduction ratio.
