The invention deals with the field of bending presses, and, more precisely, deals with a device for handling the upper table moving along guiding pillars and carrying the punch. For every table guiding pillar, the device provides for a main lever (10) hinged in a point that is substantially axial with its related guiding pillar and whose driving arm (10a) is hinged to means (9) sliding along a rod (8) hinged to the upper table. The lever resisting arm (10b), whose length is approximately 8-10 times shorter that the driving arm length, rotates a crank (12) connected through an eccentric (13) or a connection rod to a connecting rod (14) that transmits the translating motion to the upper table. <IMAGE> |
