Abstract
The utility model discloses a rear retaining device of a bending machine. The rear retaining device comprises a speed reducing motor and two retaining units. Each retaining unit comprises two fixing plates, a screw rod and a guide rail. The screw rods and the guide rails are arranged between the fixing plates. Lifting mechanisms horizontally sliding along the guide rails are arranged on the guide rails and are in thread connection with the screw rods. Retaining pieces are arranged on the lifting mechanisms. The screw rods are connected with the speed reducing motor through a transmission mechanism. Sliding of the lifting mechanisms on the guide rails is effectively realized, so that limiting adjustment of plates is realized. The lifting mechanisms and the screw rods are in thread connection, so that accurate positioning of the plates before bending is effectively realized. Displacement caused by the fact that the plates are stressed during bending is avoided, and performance of the bending machine is greatly improved. The screw rods are connected with the speed reducing motor through the transmission mechanism, and the speed reducing motor controls the retaining pieces to realize limiting and accurate positioning, so that the rear retaining device is simple and convenient to operate, time saving, labor saving and high in efficiency.
