Abstract

Abstract

In die drawing,the energy consumption of compress deformation and friction is analyzed,as well as that of velocity change at the diameter transition zone in the process of wire drawing.The upper bound theorem is applied to derive the formula of the above three energy consumption in drawing process,then the formula of the total energy consumption in drawing process is derived,and the best reduction angle of polycrystalline diamond drawing die for drawing ϕ0.12 mm steel wire is calculated out.The results show that the best reduction angle and the minimum drawing force of polycrystalline diamond drawing die are α=3.675° and F=2.49 Nseparately.when drawing ϕ0.12 mm steel wire
