Abstract
The die profile plays a significant role in smooth flow of material and evolution of uniform microstructure. It is observed that the quality of extruded product is better in converging die in comparison to flat-faced square die in general. The non-linear converging dies have some advantages over linear converging dies in terms of reduction in extrusion load, improvement in flow characteristics and evolution of uniform microstructure. The cosine die profile is observed to be the most ideal die profile with zero velocity discontinuity at the exit and entry plane. In the present investigation a die profile is designed for extrusion of square section from round billet with a cosine die profile. It is proposed to carry out FEM modeling using DEFORM-3D software for lead and aluminum.
