Optimizing the Geometry of Piercing Stub Mandrels for Tube Extrusion

Results of Deform 2D simulation of and experiments on the extrusion of aluminum-alloy tubes with piercing stub mandrels are discussed. The effect of the cone angle and the mandrel position relative to the parallel land of the die on the compressive force and strain intensity is evaluated using an ex...

Summary:Results of Deform 2D simulation of and experiments on the extrusion of aluminum-alloy tubes with piercing stub mandrels are discussed. The effect of the cone angle and the mandrel position relative to the parallel land of the die on the compressive force and strain intensity is evaluated using an experimental design and a coordinate grid. A method for optimizing the geometry of piercing stub mandrels is proposed.
