The "torsion shaft" (also known as the "torsion bar") is the key to the machine, and it determines the core working mode and characteristics of the machine.

1. The cylinders on both sides are driven by hydraulic oil to push the slider up (for downward movement) or down (for upward movement).

2. Because the torsion shaft is rigidly connected, it forces the cylinders on both sides to move synchronously, like a hard lever, to ensure that the left and right ends of the slider are always at the same height.

3. This synchronization is purely mechanical and coercive, avoiding slider tilting (commonly known as "head scratching") due to a lack of synchronization in the hydraulic system.

4 Core features: High stability and resistance to eccentric loads Function: Due to the forced synchronization of the mechanical torsion shaft, the slider can maintain extremely high parallelism without severe tilting even when processing asymmetrical workpieces or performing eccentric bending on sheet metal, thus ensuring the bending quality of the workpiece and protecting the die. Advantage: This inherent mechanical synchronization structure makes it excellent in terms of stability and reliability, with a relatively low failure rate.

5 Application of the numerical control system Function: While the slider synchronization is mechanical, it can still be equipped with a numerical control system. The "numerical control" here mainly controls: Rear stopper: The front and back positions of the rear stopper can be precisely controlled to ensure the bending dimensions.

Bending depth: The deflection point of the hydraulic system is controlled by the numerical control system to indirectly control the bottom dead center of the slider, thereby controlling the bending Angle.

Working cycle: The automatic cycle of "down - bend - hold - return" can be programmed.
