Abstract
In an indirect extrusion drawing press comprising a fixed crosspiece to which is fixed a tubular ram which is perforated by an axial orifice for the removal of the wire, a fixed bearing member, a movable crosspiece which is moved by a main jack bearing against the bearing member, a container in which is provided the bore of the billet, and which is interposed between the movable crosspiece and the ram, and a container bottom which is placed on the movable crosspiece along the axis of extrusion and which presses against the container during extrusion, the container being driven towards the ram by the movable crosspiece. A mechanism is provided for fixing the container relative to the movable crosspiece during extrusion so that auxiliary jacks, provided for moving the container independently of the crosspiece, can be used during extrusion to assist the main jack.
