Investigation of Extrusion of Lead experimentally from Round section through Equilateral Triangular section Converging dies at different area reductions during Forward Metal Extrusion Process

Abstract

The changes of die angle, area reduction in dies, loading rate on the final extruded products, extrusion pressures of lead of circular cross sections has been investigated experimentally. The proposed method is successfully adapted to the forward extrusion of the equilateral triangular section from round billet through converging dies of different area reductions. Computation of extrusion pressure at various area reductions and calculations of different parameters (stress, strain etc.) in wet condition.
