The machine adopts a variable center distance and electro-hydraulic control drive structure. The right bearing seat of the upper roller is connected to the main oil cylinder through a pin shaft. Simply remove the connecting bolt to axially withdraw and quickly complete the roller replacement work.

This model has superior performance and easy operation. It has a pre bending function at the end of the sheet metal, which can load the metal sheet metal in one go without turning the head to complete the pre bending of the sheet metal end and the rolling forming of the workpiece. The control mode of this machine isNC control, the upper roller lifting adopts displacement sensor detection, and the LED display can directly observe the working displacement of the upper roller, which has the advantages of simple operation, convenience, and high efficiency.

The electrical system adopts German technologyIntelligent high-speed PLCs and corresponding input/output modules produced by Siemens, Taiwan Advantech industrial computers, and Samsung or Siemens LCD displays. The displacement sensor adopts the German "Baruff" magnetostrictive displacement sensor to detect the position, ensuring the accuracy of the upper roller position and the monitoring of the upper roller position; The pressure sensor adopts the AK-4 product from Beijing "701" Research Institute to set and monitor the upper and lower chamber pressure of the main oil cylinder. This configuration has been proven to have strong anti-interference ability, long service life, earthquake resistance, and stable operation in the long-term process of supporting various users. It is suitable for industrial environments such as humidity, high temperature, vibration, welding, and outdoor environments.

This machine has a digital display function, mainly controlling the synchronization accuracy of the upper rollers, while monitoring the pressure changes of the two main cylinders and the pressure and displacement displayed on various digital displays.
