SC independent bending follower device for press brake is an auxiliary bending device that is used to intelligently support and follow-up adjust the workpiece during the bending process to prevent the workpiece from losing bending accuracy due to gravity, deformation or operating errors. The device operates independently of the main press brake machine, but can be linked with the CNC control system to achieve precise and synchronous bending support functions.
1. What is an independent bending follower for press brake?
SC independent bending follower is an intelligent auxiliary system for supporting and synchronously moving the plate. It can automatically adjust the support force according to the bending angle, position and speed to reduce the deformation of the workpiece, improve the bending accuracy and reduce the burden on the operator.
The device is independent of the main machine of the CNC press brake and can realize follow-up support according to the bending process requirements. It works synchronously with the movement of the slider to keep the workpiece in a reasonable support state at all times.
2. Main functions and effects of independent sheet follower
1) Plate support function
During the bending process, especially for longer, thinner or heavier plates, the follower device can provide appropriate support to prevent sagging and deformation caused by gravity or deadweight.
2) Automatic follower adjustment
The device is usually driven by a servo motor or hydraulic system, and combined with a numerical control system (CNC), it can adjust the support force, lifting height and angle in real time to match the descending speed and angle of the slider.
3) Correcting bending errors
Since the plate will rebound during bending, the independent follower device can reduce the uneven deformation of the plate due to inertial sagging, and improve the bending accuracy and consistency.
4) Reduce manual labor intensity
In traditional manual bending, the operator is required to provide support under the workpiece, especially for super-long, super-wide or heavy workpieces, which is labor-intensive and difficult to operate. The follower device can automatically support and move, greatly reducing manual operation and improving safety and production efficiency.
3. SC independent bending follower composition and configuration
The press brake independent follower generally consists of the following parts.
Component table:
Component Name | Key Features |
Support platform | Responsible for carrying the workpiece, the surface is usually made of wear-resistant material to reduce friction and improve stability. |
Servo motor | Responsible for driving the follower device to rise and fall, move forward and backward, and achieve automatic synchronous support. |
Sensor system | Monitor the position, bending angle and pressure of the plate to optimize the support strength |
Control system | Control the follower device through an independent PLC to achieve precise synchronous control |
Detailed Configuration of SC independent bending follower device:
- It can be equipped with all brands and models of top-moving press brakemachines (hybrid CNC press brake machines, electro-hydraulic press brake machines, torsion axis bending machines).
- The main body is an independent structure, and there is no need to change the mechanical parts of the bending machine. The base is a Fuma wheel structure that can be moved at any time.
- The support table is equipped with a universal ball to facilitate the movement and rotation direction of the workpiece, conducive to bending the workpiece.
- The height of the support table can be fine-tuned up and down, convenient for installing molds of different heights.
- Independent PLC control system, using magnetic scale to feedback information to the computer. The computer controls the servo motor closed loop to perform follow-up action.
- The follow-up flipping speed can be adjusted according to different plate thicknesses. There is no need to change the bending machine control system, and standard bending does not require programming. The human-machine interface can be programmable or manually operated.
- No need to modify the bending machine. You only need to drill a hole in the slider of the bending machine to install a displacement sensor, and connect it to the incoming line interface of the bending machine to use it. Avoid the risk of failure caused by modifying the bending machine electrical box and taking the bending machine signal. It also avoids industrial accidents such as the bending machine’s blade dropping and pressing the operator’s hand due to interference of the bending machine signal by the bending follwer.
4. Features and advantages of independent bending follow-up device
1) Equipment features
Independent control system:
The device is independent of the bending machine and can be intelligently synchronized according to the movement of the bending machine without directly relying on the hydraulic or mechanical drive of the bending machine.

Intelligent follow-up function:
The servo motor, hydraulic drive or pneumatic system can automatically adjust the support height and angle according to the bending angle, slider position and workpiece deformation.
Keep synchronization with the plate during the bending process to avoid accuracy errors caused by plate sagging.
High-precision sensor:
The photoelectric sensor, laser distance sensor or pressure sensor monitors the plate position in real time and makes dynamic adjustments to improve the bending accuracy.
