The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and can process workpieces with side walls, and the operation is also very simple.

[0003] The positioning mechanism of the existing electro-hydraulic bending machine adopts an overall independent structure, and its positioning effect on the plate is relatively simple, and it cannot be well controlled according to the bending size. It is often necessary to perform self-regulation on the operating table. This method is likely to cause a high error rate of the bent parts and waste of materials. For this reason, the utility model provides a multi-axis automatic positioning electro-hydraulic bending machine. Utility Model Content

The other end of the shaft rod is connected to the outer side surface of another group of positioning blocks. A pressure plate is installed on the front side of the frontmost positioning block through the shaft rod.

[0007] Preferably, the front side of the sliding machine plate is fixedly connected to the bending knife assembly via a fixing structure.
