The effect of the length of the drawing die sizing portion on the energy and force parameters of the medium-carbon steel wire drawing process

Abstract

The paper discusses a theoretical and an experimental analyses of steel wire drawing in conical drawing dies with a varying length of the die sizing portion. The theoretical analysis was performed in the Drawing 2D, where the wire temperature and drawing stress were determined. The theoretical study was verified by the measurement of drawing force under laboratory conditions and by industrial multi-stage drawing tests carried out under commercial conditions. A relationship has been shown to exist between die sizing portion length and wire temperature and drawing stress.
