A press for the direct extrusion (100) of billets comprises a shear (6) for cutting the bottom precisely along a plane orthogonal to the extrusion axis (X) which is carried by the columns (9′, 9″) by means of sliding guides (13′, 13″), so as to allow the shear (6) to slide and to position in different points along the extrusion axis (X) in different steps of the extrusion operation to carry out the cutting operation and to position in quiescent position during which the easy replacement of the container (3) may also be carried out. |
