Abstract: A bender machine designed to bend and shape sheet metal comprising a blade holder unit (1) which has a “C” shaped section, which is mobile and moves in two directions, both of which are at right angles to a fixed bench, and where the unit is fitted with one or more bending blades, wherein:servomotors and planetary gear reducers are used for moving the blade holder unit (1); the blade holder unit (1) uses a jointed mechanism comprising two mechanical units (20, 20a; 30, 30a) which form a closed kinematic chain of five components connected by five kinematic pairs all of which are revolute; the mechanical unit (20, 20a) for moving the blade holder unit (1) in a substantially vertical direction comprises a pair of servomotors coupled respectively to two gear reducers, which operate respective cranks (9, 9a) on which respective connecting rods (8, 8a) are hinged, and where the other end of each connecting rod is connected by respective pins (7, 7a) to a respective base (10, 10a) fixed to the blade holder unit (1). The mechanical unit (30, 30a) for moving the blade holder unit (1) in a substantially horizontal direction comprises one pair of servomotors (6, 6a) coupled to corresponding planetary gear reducers, each of which operates a respective camshaft (3, 3a), and also characterised in that the camshafts (3, 3a) are hinged on the rear supports (2, 2a) of the blade holder unit (1).
