    • In some hydraulic pipe benders, a mandrel is used to support the inner wall of the pipe during bending, preventing collapse or distortion.
    • The mandrel is inserted into the pipe before bending and is typically withdrawn afterward using a mandrel extraction system.
  5. Pressure Die:
    • The pressure die provides additional support to the outer wall of the pipe, ensuring uniform bending and preventing deformation.
    • It applies pressure against the pipe surface opposite the bending die, helping to maintain the pipe’s shape and integrity during bending.
  6. Control Panel:
    • The control panel houses the controls and interface for operating the hydraulic pipe bender.
    • It may include buttons, switches, and digital displays for adjusting bending parameters such as angle, radius, and speed.
  7. Hydraulic Power Unit:
    • The hydraulic power unit supplies pressurized hydraulic fluid to the hydraulic cylinder, enabling it to generate bending force.
    • It typically includes a reservoir, pump, motor, valves, and hoses for hydraulic fluid distribution.
  8. Frame and Base:
    • The frame and base provide structural support and stability to the hydraulic pipe bender.
    • They are often made of heavy-duty materials such as steel or cast iron to withstand the bending forces and vibrations generated during operation.
  9. Foot Pedal or Remote Control:
    • Some hydraulic pipe benders are equipped with a foot pedal or remote control device for hands-free operation.
    • These controls allow the operator to activate the bending process while maintaining a safe distance from the machine.
  10. Safety Features:
    • Various safety features may be incorporated into hydraulic pipe benders to protect operators and prevent accidents.
    • These may include emergency stop buttons, safety interlocks, protective guards, and warning lights.
