The upper roller of the machine is the main driving roller, and the main transmission is composed of hydraulic motors, planetary reducers, etc. The motor rotates forward and backward to achieve the forward and backward movement of the sheet metal, mainly providing torque for the rolled sheet metal. The equipment has measures to prevent steel plates from slipping. Each motor is equipped with an instant brake, which enables the roller to accurately stop rotating during bending work, ensuring precise positioning of the plate end, preventing the steel plate from slipping off the machine, and minimizing the remaining straight edges.

The lower and side lifting are driven by hydraulic cylinders, which can quickly lift and lower when unloaded and slowly lift and lower when loaded, making it more energy-efficient.

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 the machine is numerical control, and the lifting of the lower and side rollers is detected by encoders,CRT display can directly observe the working displacement of the lower and side rollers, and has the advantages of simple operation, instant noodles, and high efficiency.

The electrical system adopts Japanese technologyThe intelligent high-speed PLC produced by "OMRON" company, along with corresponding input and output modules and "Weilun" touch screens. The encoder uses Korean "Autonex" to detect the position, ensuring the accuracy of the position of the lower and side rollers and monitoring the position of the lower roller; 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 CNC function, mainly controlling the synchronization accuracy of the lower and side rollers, while monitoring the pressure and displacement displayed on the various CNC tables of the two main cylinders.
