Novelty: It is disclosed a mechanism designed for the configuration of three-dimensional spiral and flat schemes/stirrups made of iron rods advanced to the bending mechanism one by one or by twos or, synchronically, in groups in order to be configurated. Constitution: The central bending plate (4) moving up and down through the pistons (7), the bending pin (15) of said bending plate, and the steady bending accessory (17) adapted to the base (18) which is connected to the up-and-down reciprocating piston (19). The configuration mechanism (2) is composed of the bending accessory (27) and the bending accessory (28) which is liable to inwardly-outwardly move with the assistance of the piston (29). Three-dimensional bending is achieved by rotation of the bending mechanism which, being displaced to the "upper position" via the piston (35), is able to configurate three-dimensional and spiral shapes the configurated side of which is perpendicular to the horizontal sides of the shape and under left or right angle in respect to the perpendicular sides. |
