Single motor bending device for metal profiles, has motor mounted on endless reductor comprising triangular configuration of fixed outer rollers and displaceable central roller

摘要

The electric motor is mounted on an endless reductor which transmits rotary movement of the motor to three parallel rollers arranged in a triangular configuration on top of the work bench. The two outer rollers rotate in one direction and have fixed positions and the central roller rotates in the opposite direction and can be displaced in its length direction. Rotary movement is transmitted to the rollers via ball and socket joints. The rollers have identical internal diameters but can have different external diameters and dimensions, depending on the desired bending pattern. The central roller is guided by a crank or reductor.
