<p>A kinematic system of movement for the clamping/pressing unit of a semifinished piece, that is to say of sheet metal or the like, of panelling machines, the kinematic system comprising a frame (10) on which a presser unit (12) is hinged to a pin (11) and which is free to make angular movements around the pin (11), the presser unit (12) consisting of elements v (13) fixed to a head (14) supporting the upper presser tool (15), the presser unit (12) being moved angularly by at least one connecting rod (16) driven by a first lower crank (17), in which the presser unit (12) is driven by a second upper crank (18), the first (17) and second (18) crank defining an articulated mechanism, for driving the punch-presser unit, with two degrees of freedom in sequence that can be activated independently or simultaneously.</p> |
