System for adjusting sliding blocks of a movable crosspiece of a press

An adjustment system for adjusting a position of at least one sliding block of a movable crosspiece of a press with respect to a respective column of the press on which said sliding block can slide, the adjustment system comprising

• a first wedge, adapted to be integral with said movable crosspiece;
• a second wedge on which said sliding block can be fixed, said second wedge being adapted to slide on said first wedge;
• a pin defining an axis and having a first eccentric end with respect to said axis, said first eccentric end being accommodated in a cavity provided in said second wedge;
• first actuating means for actuating the pin adapted to rotate said pin about the axis, so that by rotating the pin, the first eccentric end causes a sliding of the second wedge on the first wedge along a direction transversal to the axis;
• wherein second actuating means for actuating the pin are provided, adapted to translate the pin along said axis from a first position in which the pin is locked to a second position in which the pin is unlocked and can rotate about the axis,
• and wherein said pin is arranged completely external to the first wedge.
