Plate Bending Machine

1. Plate Bending Machine Preface

The mechanical and hydraulic systems on this plate bending machine are designed by our experienced engineers. These engineers design the machines utilizing parametric 3D engineering technology as well as implementation of mechanical and static analysis. All mechanical, hydraulic, and electronic systems are designed and tested by electrical and mechanical engineers. Only following lengthy tests and evaluations are the machines authorized to be manufactured in serial production.

2. High Torque Drive System of Plate Bending Machine

Because of its high torque drive, this machine bends the part with fewer steps. Rolls are powered by independent high torque hydraulic motors and planetary gear boxes.
The activation system is positioned on the same axis as the roll, so high torque is transferred to the sheet without any power loss. Especially during the pre-bending, the hydraulic breaks does not allow the plate to slip back which may create safety problems.

3. Hydraulic and Electrical System of Plate Bending Machine

Machine movements are provided by hydraulic components. The precision on the all axes are acquired by world leader Parker valves’ high speed response ability. And pressure safety valves used against peak pressures and overload provides protection for motors and other components. Electrical system designed compatible with CE safety regulations. The system is protected by current overloading for its components’, power supplies, electronics and motors.

4. Plate Bending Machine Advantages

(1) The bottom roll moves up to hold the plate edge securely against the top roll while the side roll is raised to form an accurate pre-bend, minimizing the flat zone on the plate edge. Pre-bending on a three roll machine requires that plates be tilted down as they are being fed. In contrast, plates are loaded horizontally at the feed level for pre-bending on a four roll machine, which allows the ake place on either side of a four roll machine. If fed from only one side, they can even be placed up against a wall to save floor space.

(2) The side rolls are positioned to the right and left of the bottom roll and are on their own axes. The independent axis of each roll helps make a perfect bend. The “back” side roll (at the far side of the feeding point) also functions as a back gauge to square the plate for proper alignment. This eliminates the need for someone to assist the operator.

(3) The fastest and most accurate bends are made by four roll machines. The plate is held securely in place between the top and bottom rolls while the side rolls move vertically to create the bend.
