Abstract (en)
A method for the automatic angular timing of a mandrel (7) of an extrusion press (1) with respect to an extrusion die (4) placed in a container (3) containing a billet to be extruded, the mandrel (7) being carried by a support member (15) and being subject to the thrust of a drilling piston (9), said mandrel (7) rotating about its longitudinal axis through the rotation about a same axis of such support member (15) placed within a fixed body (6), the mandrel (7) having a free end or head (8) adapted to cooperate with the billet during the extrusion. A first slow rotation of the mandrel (7) is carried out to make a first timing with respect to the extrusion die (4), a sample extrusion is carried out and the resulting piece is checked, at least a one further controlled rotation at low mandrel speeds being carried out before implementing a subsequent extrusion. The device for carrying out such method is also claimed.
