3 roller flat plate bending machines have many advantages. They are reliable and tested hydraulic bending machines with three drive rollers with hydraulic clamping to ensure precise and constant resistance of the material.
The equipment is reliable and efficient. The parallelism of the side rollers is controlled by the torsion bar system connecting the two ends of the side rollers, which eliminates the shortcomings of precision and unreliable encoders. The roller is driven by a hydraulic motor and a high-efficiency planetary gear box, and is directly connected to the roller. CHAOLI assembles the roller on a sealed bearing and does not contain secondary parts, which can reduce the dispersion of the force generated by the friction of various parts. It guarantees higher reliability, greater load absorption capacity, and increases the tilting ability of the side rollers, thereby achieving conical bending.
The side rollers move up and down on the planetary rotary guide: the perfect geometry eliminates the shortcomings of linear gears. This allows us to use hydraulic pumps with low-flow motors, thereby increasing energy savings.
Both movement and roller parallelism are electronically driven.
Two proportional solenoid valves, two sensors and a dedicated system provide accuracy, stability and repeatability over time under any temperature and conditions
The side rollers move on the linear inclined channel, reducing the space between the rollers. Due to the narrow center distance, the contact points between the side rollers and the metal plate occur in a shorter space; this allows the use of very small diameters to further reduce the flat edges. In this model, the parallelism of the rollers is electronic; two proportional electronic valves, two sensors with digital readings and a dedicated electronic control device can ensure the accuracy and repeatability of each roller positioning over time. Affected by temperature or any mechanical wear, the maximum accuracy is always achieved.
