ABSTRACT:
A bending machine designed to bend and shape sheet metal comprises a blade-holder unit (10) with a “C” shaped cross-section, mobile along two mutually orthogonal directions with respect to a fixed bed, and on which one or more bending blades are fixed. This machine comprises a kinematic system for driving the operating units, in which servomotors (15, 21, 22) and epicyclical reduction gears are used for the movement of the blade-holder unit (10). Moreover, the blade-holder unit (10) of the bending machine uses an articulated mechanism consisting of two mechanical units (13, 14) which form a closed kinematic chain with five members connected by five kinematic turning pairs.
