During the bending process, the sheet metal is subjected to a local impact force. If there is no support frame for the lower part of the sheet metal, the impact force on the sheet metal during bending will diverge outward, causing significant deformation and affecting the bending quality of the sheet metal. So the complexity of this mechanism lies in the fact that the motion trajectory of its support plate must be completely consistent with the motion trajectory of the workpiece flipping during the bending process, and the motion speed also needs to be kept consistent to ensure that the plate is always subjected to a supporting force and does not deform. In addition to the fact that the motion trajectory and speed of the two must be consistent, the height of the mold and the width of the mold opening are different when bending different thicknesses of sheet metal, which causes changes in the starting position and rotation bending fulcrum of the sheet metal when flipping up. All these uncertain factors pose higher requirements for the motion trajectory, speed control, and position adjustment of the follow-up feeding mechanism.

At present, most factories manually support materials, and ordinary small materials only require one person to operate a bending machine. However, when it comes to large sheet metal, it often requires 4-6 people to operate a bending machine. Extremely labor-intensive, and the instability of manual palletizing can easily cause product quality problems, which is also not conducive to production control.

Some press brake machine manufacturers also come with their own material support frames, but they often cannot synchronize their operation with the sheet metal. During the bending process, there is often a period of time when the sheet metal and the support frame cannot fit tightly, resulting in shaking of the sheet metal during the bending process, poor stability, and easy damage; Secondly, when bending different sheet materials, it is often necessary to adjust the position of the pallets appropriately in order to ensure a tight fit between the pallets and the sheet materials. However, the current pallets are driven by oil cylinder chains, and the adjustment distance cannot be determined, resulting in a decrease in adjustment accuracy. The entire adjustment structure is complex and has poor practicality.

SC press brake sheet follower can always hold and follow up with the sheet plate during the bending process. The magnetic grating ruler of SC SHENCHONG bending follower roughly indicates the position of the upper mold pressing down, and calculates the real-time flipping angle of the plate based on the size of the groove and the thickness of the plate. The servo motor controls the rotation angle of the active rod to be consistent with the calculated value, ensuring that the surface of the following trolley is always in contact with the sheet metal during the bending process, preventing displacement of the sheet metal and improving the bending accuracy.
