Numerical Simulation of Eccentric Extrusion Form Bending Pipe Parts

Abstract:

Eccentric extrusion method is used in this paper，through this method achieved bending aluminum-alloy tube extrusion forming process. Used finite element method，achieved three-dimensional numerical simulation of bending aluminum-alloy tube in eccentric extrusion by DEFORM-3D finite element commercial software，analyzed velocity field distribution，material flow，squeezing pressure，stress and strain field distribution of the process；Introduce the mechanism of one step direct extrusion forming tube bending process，it will be of great guiding significance the actual die design.
