[0031] Working principle: In the process of producing and processing hexagonal wrenches, steel is cut according to size and needs to be processed using a turning device to ensure that it can meet the use requirements. However, when the existing hexagonal wrench processing and bending device is in operation, the staff needs to assist in feeding, which makes the preparation work of the bending process time-consuming. The present application works through the feeding device, inserting the steel to be bent into the first clamping cavity 410 on the feeding base 409, opening the No. 1 telescopic cylinder 412, and under the cooperation of the No. 1 slider 415 and the first slide groove 411, the No. 1 telescopic rod 413 drives the No. 1 telescopic rod 413 to move ...

The fixing function of the bent steel realizes the function of automatic feeding and improves the efficiency of the preliminary preparation work. In addition, when the hexagonal wrench steels of different sizes are bent in different positions during the bending process, the staff needs to repeatedly adjust the position of the bending point, and there is a size error during the adjustment process, resulting in poor accuracy of the bending operation and affecting the quality of the product. The present application uses the positioning device for auxiliary function. According to the size of the steel to be bent, a force is applied to the rotating button 504, and the screw rod 503 rotates. Under the action of the sliding rod 502 and the scale, the support block 505 drives the positioning plate 506 along the structural groove 50 1 moves to the specified position. When the end of the steel moves to the end surface of the action plate 509, the action plate 509 is stressed, the spring 508 is compressed, and the action plate 509 applies a force to the pressure sensor 510. The model of the pressure sensor 510 is PT124G-210. The pressure sensor 510 acts to stop the motor 404, and the hydraulic cylinder 7 acts.
