First, loosen the fixed clamp. When asked, the movable clamp clamps the processed aluminum tube and moves forward along the guide rail; after moving forward, the limit switch sends a signal to prompt the fixed clamp to clamp the aluminum tube, and the movable clamp follows Release and move back to reset; then the left bending machine starts to work, and the rotating table moves to the left. The left corner is in place to send a signal, prompting the right corner machine to start working, and the workbench turns right. When the right bending is in place, it is determined whether to continue processing or finish processing according to the bending times counter. If the processing is finished, cut the aluminum tube, and then perform the second cycle.
