Abstract
An electric powered extrusion press pushes an extrusion stem by extrusion force generated by an electric powered drive device so that pressure is applied to a billet and a predetermined product is extruded through a die, wherein the electric powered drive device is provided with one or more freely rotatable wire drums, an electric powered extrusion-use main motor makes the wire drums rotate wind up wires and thereby give a thrust to movable pulleys in the extrusion direction so that a crosshead and extrusion stem are driven to advance through an extrusion movement part.
