Abstract

A proposed die configuration is designed to effect the in-process compensation of the errors in the form of the extrudate which arise from the elasticity of the extrusion dies. The die is in the form of a truncated, conical-shell which is either on a plane or a spherical bearing surface, to enable it to deflect elastically, thereby changing the dimension of the die orifice. FE simulation of the work-material flow and the die deflection was conducted to verify the feasibility of the proposed configuration. The deflection of the die is a function of the extrusion force and the resulting reduction of the die orifice is in proportion to this force. The simulation enabled optimisation of the geometric parameters of the die with respect to component-form errors.
