Dynamic Control with 3D Guide Rollers

A defining feature of the PBH series is the integration of 3D guide rollers, enabling precise control over the rolling process. Through PCL control, these rollers facilitate three key movements: vertical adjustment, arc motion synchronization with the lower roller, and rotational motion. This dynamic control mechanism, complemented by digital motion state displays, ensures superior forming quality and dimensional accuracy.

The 3D guide roller can realize three movements through PCL control:

  • Up and down movement. It can cooperate with the lower roller to make arc rising and falling movements at the same time;
  • It can perform rotating motion at the same time, and the digital display of the motion state is eye-catching and intuitive, and the forming quality of the profile during the rolling process can be observed at any time;
  • By adjusting two more powerful horizontal hydraulic 3D guide rollers, they can be adjusted in the six directions of up and down, left and right movement, and push/pull, respectively, and can support and accompany curved profiles to ensure optimal control of the rolling level Straightness and correct the deformation of the profile rolling process.

Enhanced Flexibility with Independent Mobile Operation Table

The inclusion of an independent mobile operation table enhances operator safety and ease of use. This feature allows operators to maneuver and control the machine with utmost convenience, optimizing workflow efficiency.

The independent mobile operation table plays a crucial role in ensuring operator safety and facilitating ease of use.
