Abstract (en)
An extrusion press comprises a device (15) for automatically checking the eccentricity of a mandrel (7) of such press (1), said mandrel (7) being movable with respect to a container (3) of a billet to be extruded and to an extrusion die (4) integral with said container, said mandrel (7) being movable along a longitudinal axis (W) thereof and being rotatable about it, such mandrel (7) being insertable within the extrusion die (4) and the container (3) with said movement along the axis (W) thereof in order to carry out the extrusion of the billet. Detecting means (20) are provided adapted to detect the eccentricity of the mandrel (7) outside the container (3) of the billet, said means (20) being placed in the vicinity of the mandrel and detecting the eccentricity of such mandrel during a movement towards or away from the container (3) of the billet, such detection intervening during the rotation of said mandrel.
