Based on the feedback signal from position sensor 7, controller 8 adjusts the movement of drive motor 4 and Z-axis adjusting screw 33 in real time to ensure the bending head accurately reaches the designated working area. Once the bending head reaches the designated working area, controller 8 controls the compression cylinder 5 to press down, causing the bending head to bend the workpiece. After bending is complete, controller 8 controls the compression cylinder 5 to reset, preparing for the next workpiece bending operation. Position sensor 7 and controller 8 can be set with limit protection to prevent the bending head from exceeding the predetermined working area and avoid accidents. Controller 8 will immediately stop the equipment when it detects an abnormality to ensure operational safety.
