Sheet Follower - A Good Helper For Press Brakes

The Press Brake Follow-up Device

When bending workpieces, press brakes often process workpieces with longer lengths and larger weights. When the bending machine is made, the workpiece will be closed with the mold, and the sheet metal on both sides of the bending line will turn upward. In order to avoid the bending accuracy of the workpiece due to bending and gravity of the overly long or heavy sheet, we recommend equipping the press brake follow-up device. 

Novel Design of Follow-up Device

Press brake follow-up device, using novel design, servo motor drive, wider table and larger load force, according to the movement trajectory of the workpiece when bending, the pallet can always follow the movement of the workpiece sheet, while ensuring the bending accuracy of the workpiece, it greatly saves the difficulty of manpower auxiliary feeding. Through the cooperation of linear motion and rotary motion of the pallet, the trajectory and speed of the turning can be accurately matched with the reversal and speed of the plate when bending, and this follow-up device is a fully automatic CNC independent motion axis.

Applicable Occasions of Follow-up Device

Follow-up device dragging assists bending. Multi-variety, large and small batch production can use this way, large workpiece, thick plate bending advantages are obvious, reduce bending auxiliary personnel, reduce labor intensity, strong flexibility, a follow-up drag material can be used with multiple bending machines, the investment cost is relatively low. 

Special Advantages of Follow-up Device

1. Save labor

2. Improve the processing efficiency of machine tools

3. The follower device and the plate bending action are fully synchronized

4. It can be matched with various brands and models of bending machines

5. Independent control system, no need to modify the bending machine, no need to take any signal from the electrical box of the bending machine, avoid unnecessary trouble

6. It can be moved at any time to match the bending machine for use

Composition Structure of Follow-up Device

The follow-up device bracket is usually connected to the press brake, and it includes a bracket, a bracket mechanism, a guide mechanism, a drive mechanism and a transmission mechanism, mainly connected to the bending machine through the bracket part, and the rest of the guide mechanism, drive mechanism and transmission mechanism are connected to the bracket , and then the carrier mechanism is connected to the guide mechanism, and finally the drive mechanism drives the carrier mechanism to move along the guide mechanism through the transmission mechanism. The follow-up device as a whole has the characteristics of stable structure, good use effect and long service life. 

Structure Diagram of Follow-up Device

The figure below is the structural diagram of the follow-up bracket of the press brake, including the frame [1], located above the frame [1] and relative to the frame [ 1] Sliding upper mold slider [2], used to lift the workpiece to be machined [3] relative to the frame [1]. A support table [4] set in phase, a drive mechanism that drives a support table [4] to rotate, and a support table [ 4] Cooperate with the upper mold slider [2] to synchronize the action, and bend the workpiece [3] to be processed, and the upper mold slider [ 2] and the workpiece to be machined [3] close to the formation of a bending centerline, which is characterized in that: the drive mechanism includes: the drive rod [5],  One end of the drive lever [5] and one end of the support table [4] pass through the first hinge [6]. Connected by phase rotation; The first bushing [7], the other end of the first bushing [7] and the drive rod [5] pass through the second shaft [8] Phase rotation setting; The upper end of the first screw [9] and the support table [4] pass through the third hinge [10] is connected in phase rotation, the first screw [9] and the first bushing [7]. ] to match; The upper end of the second bushing [11], the second bushing [11] and the drive rod [5]. ] Connected fixedly; The length of the second screw [12], the second screw [12] extends in the direction of up and down, and the second screw [12]. In conjunction with the second bushing [11], the drive mechanism also includes a drive for the second screw [12]. The rotating drive motor, the drive motor is a servo motor, and the servo motor controls the rotation of the second screw [12] through programming, and then controls the support table [4] relative to the frame [1] rotation angle.
