摘要： The present invention relates to a press (1) for the direct extrusion of metallic material. The press comprises a supporting structure (10), a container (5) receiving the metallic material to be extruded, a container holder element (6) and a plurality of adjustment devices (15A,15B) to adjust the position of the container holder (6) with respect to the supporting structure (10). The container holder element is movable along an extrusion direction (500) by means of a plurality of pads (11A, 11B) slidable along corresponding guides (12A, 12B) integral with the supporting structure. The press comprises at least one motorized member (16A,16B) operationally connected to at least one of the adjustment devices (15A,15B) to determine a variation of the position of the container holder with respect to the supporting structure.

摘要： The present invention relates to a press (1) for the direct extrusion of metallic material, wherein the press (1) comprises a supporting structure (10) which defines an extrusion axis (500) and a transverse direction orthogonal to said extrusion axis. The press further comprises an extrusion die (2) and a die-holder drawer (20), in which said die is placed. Moving means (4) are provided for moving said drawer along a transverse direction between a first position (P1), in which said die is aligned with said extrusion axis (500), and a second position in which, when reached, said die can be replaced. The press according to the invention further comprises a fixed supporting element (30) which supports the drawer at least when it occupies the first position. The press further comprises at least a movable supporting element (40) for supporting said drawer during the movement along said transverse direction; lifting means are provided for vertically lifting the movable supporting element between a first vertical position, in which the drawer is supported by the fixed supporting element, and a second vertical position, in which the drawer is lifted with respect to the fixed supporting element and supported by said at least one movable supporting element.
