Effects of the semi die/plug angles on cold tube drawing with a fixed plug by FEM for AISI 1010 steel tube

Abstract

In this present paper, finite element method (FEM) is used to simulate cold tube drawing process with a fixed plug for AISI 1010 steel tube. The effects of semi die/plug angles on drawing stress for different friction coefficients at 23% reduction of area are studied. The finite element model is successfully validated with the experimental data. Results indicate that a good agreement between the experimental and the finite element method is found. Consequently, the effect of semi die angle on plastic deformation is larger than the semi plug angle because of the bigger size of the semi die angle. Semi die angle of 12 gives minimum drawing stress for all coefficient of frictions. A semi plug angle between 2 and 4 should be used in tube drawing process with a conical fixed plug when semi die angle is equal to 7o.
