SC DLSD25 Bending Follower Support Device is an intelligent auxiliary device specifically designed for use with CNC press brake bending machines. It is primarily used for automatic support, synchronous following, and dynamic lifting of workpieces during sheet metal bending.

Its core function is to replace manual material handling when bending large, long, thin, or heavy sheet metal, achieving synchronized movement between the workpiece and the bending machine's slide block. This improves bending accuracy, reduces labor intensity, and increases production efficiency.

The DLSD25 typically employs a servo drive system, high-precision sensors, and an independent control system. It automatically adjusts the position and angle of the support platform according to the bending angle, achieving intelligent follower support.

1. Working Principle of the DLSD25 Bending Follower Support Device

In traditional bending processes:

- Large sheet metal is prone to sagging due to its own weight.

- The workpiece will generate a large cantilever moment.

- Even with multiple people working together to support the material, stability is difficult to guarantee.

- Bending angle errors and workpiece scratches are very likely to occur.

During bending follower operation:

- The CNC press brake machine begins to press down.

- The displacement sensor collects the slider position in real time.

- The control system calculates the movement trajectory of the sheet metal.

- The servo motor drives the material support platform to lift synchronously.

- The material support platform maintains the same angle of movement as the workpiece.

- It automatically resets until the bending is complete.

Throughout the entire process, the material support device always supports the weight of the workpiece, ensuring even stress on the sheet metal and preventing sagging deformation.
