PPEB Series Press Brakes

Introduction
Equipped with advanced hydraulics and electronics, PPEB series brake press supply multi-axis configurations to satisfy a broad range of bending requirements. All PPEB CNC brake press is characterized by the new intuitive, intelligent and powerful CNC control, which saves time and ensures optimal bending results from the first part.

Components and characteristics

1. Microprocessor Technology for Optimum Precision

These CNC press brakes adopt the latest hydraulics and electronics, which contributes to reliable and accurate control over the bending process. In addition, a closed loop is used to control the synchronization of the ram and bending force so as to achieve proper bending depth and bending angle.

2. Linear encoders

Linear encoders are applied to the bending machine to measure ram position. The encoders are connected to the table of the press brakes in such a way that deformation of the side frames during bending does not influence the accuracy of the upper beam position.

3. Control technology:

Two linear encoders (Y1-Y2) are mounted on two sides of the bending machine. They are used to measure the exact distance between the ram and worktable. The encoders are connected to the press brake table so that the deformation of the side frames does not influence the position. The position data is immediately sent to the control system for calculation and then the output will be turned into control signal and sent to the servo valves (S1-S2). If there is any error, two servo calves will be quickly rectified by CNC system. It always ensures the balance between the ram and worktable.

4. Programmable System V-axis:

The press brakes adopt CNC system, which is designed to maintain a balanced state between the ram and table during the bending operation. After sheet thickness, length, die opening and tensile strength data are delivered into control system, force and related deflection of the bending machine table and ram could be automatically determined. Preloading is optimally obtained for bending each time.

5. Options:

1. backgauge position (X-axis)
2. backgauge vertical adjustment (R-axis)
3. Finger block transverse adjustment (Z-axis)
4. CNC crowning on worktable (V-axis)
5. Each finger block X-way movement (X1-X2 axis) (up to pressing force 2500 KN)
