The output shaft of the servo motor 2 18 firmly passes through the corresponding support bar 5 and is tightly connected to the connecting block 19 to ensure the precise transmission of force. The two adjacent connecting blocks 19 are fixedly connected with a rotating column 20. The inner side of the splint 12 and the splint 2 17 are fixedly connected with an anti-slip pad 22. These anti-slip pads 22 are made of special materials and have excellent anti-slip properties. They can ensure that the workpiece is stable and non-slip during processing, thereby improving processing accuracy and safety. The bottom of the processing table 1 is fixedly connected to the bottom plate 7. The plate 7 serves as the supporting foundation of the entire device.

The circular plug 26 is usually made of rubber or plastic materials and has good sealing properties. The main function of the controller 8 is to control the movement and operation of the processing table 1 to achieve precise control of the processing process.

[0038] Working principle: When the wire needs to be bent, the wire is first placed on the corresponding clamping plate 2 17. At this time, the servo motor 14 fixed on the elongated block 15 is turned on, thereby driving the rotating plate 13 to cooperate with the connecting plate 11 to rotate along the outer wall of the fixed plate 10. At this time, when the top of the rotating plate 13 rotates to the bottom, it contacts the top of the air cooler 16, and the air cooler 16 is pressed downward, and then the clamping plate 12 is brought into contact with the clamping plate 2 17. Finally, one end of the wire that needs to be bent is fixed. A spring 24 is fixed on the inner side of the hollow column 23 to move the sliding column 21 upward to ensure that the air cooler 16 can be reset again. Therefore, it is possible to effectively prevent loosening during the bending process of the wire and reduce manual intervention to clamp the wire, thereby improving the testing efficiency of the wire:

[0039] After that, the water source is put into the inner side of the ice maker 204 through the water supply pipe 205, and the ice maker 204 cooperates to make crushed ice from the water source, and then transports it to the inside of the cold water tank 202 through the long tube 203, and cooperates to refrigerate the water source inside the cold water tank 202. Then, the water pump 209 is started, and the cold water is transported to the inner side of the T-shaped box 201 through the delivery pipe 208. The cold air automatically generated by the cold water itself is dissipated through the air outlet plate 210 to the surface of the bent wire at the top for cooling. Finally, the air cooler 16 fixed on the long plate 29 is started to blow cold air onto the wire again. In this way, the heat caused by the sharp bending of the wire is avoided when testing the wire, and the service life of the wire is extended, which is convenient for the operator to use later.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
