CA 2533347

A bending device for bending machine comprises a matrix (2), a countermatrix (6), and a die (7) able to prevent wrinkles. A countermatrix- holder support element (8) is fixed on an upper slide (10), which is slidable transversally to a workpiece T to be bent on a lower slide (11) movable in turn in the same direction of the upper slide (10), on a table (12). A first double-acting cylinder (19), being fixed on said lower slide (11), moves the countermatrix (6) toward and away from the workpiece (T); and a second double-acting cylinder (24) is slidable on the upper slide (10) and connected to a slider (25) on a counteracting rod (26) which is pivoted about an end of an arm-turning spindle (3), so that a force is exerted on the countermatrix-holder support element (8) in a projecting portion (23) thereof.
