[0031] Specifically, when the workpiece to be processed is square, rotating the bidirectional screw 6 can drive the movable blocks 7 on both sides to move toward the middle. During this process, the square clamp 13 will move with the movement of the movable block 7, and then accurately limit the clamping of the square workpiece. This clamping method is both stable and reliable, providing a solid foundation for subsequent processing operations. When facing special-shaped workpieces, it can also show its strong adaptability. At this time, you only need to simply loosen the bolt 14 to remove the square clamp 13, and then rotate the threaded rod 10, and the upper clamping block 12 will move downward. The precise fit between the upper clamping block 12 and the lower clamping block 9 enables the device to limit the clamping of special-shaped workpieces. This design not only broadens the scope of use of the device, but also greatly improves production efficiency.

[0032] Reference Figure 1 and Figure 2The circulation mechanism 2 includes a hollow frame 201, which is arranged at the inner bottom of the hollow box 1. A filter screen 202 is fixedly connected to the middle and lower inner part of the fixed frame 3. A water pump 203 is fixedly connected to the right side of the hollow box 1. The input end of the water pump 203 passes through the hollow box 1 and the hollow frame 201 in sequence and is connected to a liquid inlet pipe 204. The output end of the water pump 203 is connected to a liquid outlet pipe 205. The bottom of the fixed frame 3 is connected to a hollow pipe 207. An electric valve 206 is arranged on the outer side of the hollow pipe 207. The bottom of the fixed plate 4 is fixedly connected to the middle of the top of the filter screen 202.

[0033] Specifically, after the cooling water is injected into the fixed frame 3, it will quickly contact the workpiece to be processed and effectively cool it. At this time, the electric valve 206 is opened, and the water source filtered by the filter screen 202 will flow into the hollow frame 201 along the designed channel. This hollow frame 201 plays an important role in the device. It is not only used to store the filtered water source, but also provides conditions for the subsequent water recycling. At this time, starting the water pump 203 can pump out the water source in the hollow frame 201 for recycling. This method can not only reduce the waste of water resources, but also greatly reduce production costs.

A protective cover 20 is arranged on the outside of the controller 19, and one side of the protective cover 20 is rotatably connected to the left side of the hollow box 1;

[0039] Specifically, the operation of the water pump 203, the electric valve 206 and the perforating head 16 can be controlled by the controller 19, and the protective cover 20 can protect the controller 19 from being damaged by external factors.

[0040] Working principle: When using the device, first observe the shape of the workpiece to be processed. When the shape of the workpiece to be processed is a square workpiece, rotating the bidirectional screw 6 can drive the movable blocks 7 on both sides to move toward the middle, and the square clamping plate 13 will move with it to limit the square workpiece. When it is necessary to limit the clamping of special-shaped workpieces, just loosen the bolts 14 to remove the square clamping plate 13, and then rotate the threaded rod 10 to drive the upper clamping block 12 to move downward. At this time, the special-shaped workpiece can be limited and clamped through the cooperation between the upper clamping block 12 and the lower clamping block 9, so that it can be suitable for workpieces of different shapes and sizes, and can meet According to the needs of the user, and after the workpiece is clamped, cooling water is injected into the fixed frame 3, and then the electrode drilling operation can be performed on the workpiece through the punching head 16.
