Abstract

Reverse extrusion press comprises a fixed and a displaceable cross beam and a container with a water cooled chamber to receive the workpiece billet. A punch with an axial bore and fitted with a die is attached to the stationary cross beam, a gap being provided between the o. d. of the punch and the interior surface of the chamber walls. The cooling of the chamber walls prevents adhesion between billet and walls facilitating removal of the remainder of the billet by means of a special stripping bush which can be inserted into a gap between the outside of the punch and the chamber walls.
