These sensors may include position sensors to determine the position of the bending arm or die, pressure sensors to monitor the pneumatic pressure, and limit switches to detect the limits of movement. The data from these sensors is used by the control system to ensure accurate and controlled bending operations.
  4. Bending Parameters: The control system allows operators to set and adjust bending parameters such as bending angle, speed, and force. These parameters can be input through the control panel and are used by the control system to regulate the movement of the bending arm and the application of pneumatic force.
  5. Speed Control: The control system enables operators to control the speed of the bending operation. This feature allows for flexibility in achieving the desired bending speed, depending on the material, pipe size, and specific bending requirements.
  6. Force Control: The control system allows for precise control of the bending force applied to the pipe. Operators can adjust the force parameters to ensure proper bending without causing damage to the pipe or the machine. This feature is particularly important when working with different pipe materials and thicknesses.
