Method for Pocket Die Design on the Basis of Numerical Investigation of Aluminium Extrusion Process

Abstract

The paper considers dependencies of metal forming characteristics on dimensionless geometrical parameters of flat pocket die design at direct extrusion of aluminium thin-walled solid profiles. The theoretical analysis of plastic metal flow is carried out by means of the 2 -D FEM model. The new method for flat pocket die design is proposed in the paper. The die design example is given for non -symmetrical U-shape profile.
