Abstract

When designing the drawing process of sections with a regular polygon profile, it is convenient to use analytical expressions that make it possible to operatively evaluate the effect of different manufacturing factors. A calculation procedure for stress in this process is proposed. The relationships are derived for the calculation of the drawing stress, the optimal angle for the drawing-tool channel, the limiting deformation rate with the use of a standard tool, and the stress-state characteristic in the axial part of the deformation zone. The application of a drawing tool with optimum angles decreases the accumulation rate for defects of the metal structure and makes it possible to decrease the number of intermediate thermal treatments during multiple drawing.
