[0002] In a three-phase system, there are usually three main conductors or busbars, called phase A, phase B and phase C, which are used to transmit three sinusoidal currents that are staggered by 120 degrees in time. The phase A busbar is a part of the power system used to transmit and distribute electrical energy, especially one of the components in a three-phase AC power system.

[0003] A-phase busbar needs to be A-phase busbar during the production process. Figure 8 The figure shows the state of the A-phase busbar before bending. Fig. 9 This is the state of the A-phase busbar after bending. Due to the complex bending structure of the A-phase busbar, it is currently often bent in single steps in sequence through multiple bending devices. Each bending requires reinstallation to the bending device, so the accuracy is low and the product quality is difficult to guarantee. At the same time, the bending efficiency is low, and there is a lot of room for improvement. Summary of the invention

[0022] 3. The contact block is used to limit the moving position of the positioning seat and to position it, to prevent the positioning seat from not moving to the specified position, resulting in incorrect bending position, resulting in low product quality or even waste.

[0023] 4. The clamping block contacts the workpiece faster than the first bending block. When the first bending block moves to contact the workpiece, the clamping block is located above the positioning seat, so that the workpiece is restricted to the positioning seat when being bent by the first bending block to prevent it from tipping over or twisting.
