Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one of the features.

[0027] An embodiment of the present invention provides a wire polishing processing device, comprising: a machine tool 1; a plurality of inner polishing wheel assemblies 2, which are arranged along the circumferential direction of the machine tool 1; and a plurality of outer polishing wheel assemblies 3, which are arranged along the circumferential direction of the machine tool 1. The plurality of outer polishing wheel assemblies 3 are all located outside the plurality of inner polishing wheel assemblies 2, and the outer polishing wheel assemblies 3 are spaced apart from the inner polishing wheel assemblies 2. The plurality of inner polishing wheel assemblies 2 and the plurality of outer polishing wheel assemblies 3 can rotate synchronously, and the rotation directions of adjacent inner polishing wheel assemblies 2 and outer polishing wheel assemblies 3 are opposite.

[0028] Specifically, Figure 1 and Figure 2 is a schematic diagram of a machine tool 1 viewed from above, and Figure 1 and Figure 2 The arrow next to the metal wire 100 represents the traveling direction of the metal wire 100 , and the arrows in the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 represent the rotation directions of the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 .

In this way, the metal wire 100 can pass through the inner polishing wheel assemblies 2 and the outer polishing wheel assemblies 3 multiple times in sequence, so that one side of the circumference of the metal wire 100 can repeatedly pass through the multiple inner polishing wheel assemblies 2, and the other side of the circumference of the metal wire 100 can repeatedly pass through the multiple outer polishing wheel assemblies 3, realizing the comprehensive and repeated polishing process of the circumference of the metal wire 100, thereby improving the polishing quality.

Figure 1 As shown, the inner polishing wheel assembly 2 rotates counterclockwise, and the outer polishing wheel assembly 3 rotates clockwise. The relative movement directions between the inner polishing wheel assembly 2, the outer polishing wheel assembly 3 and the metal wire 100 are opposite, so that the relative speed between the inner polishing wheel assembly 2, the outer polishing wheel assembly 3 and the metal wire 100 increases, thereby making the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 have a stronger cutting effect on the metal wire 100, which helps to quickly remove thicker oxide layers or rougher surfaces, such as Figure 2 As shown, the inner polishing wheel assembly 2 rotates clockwise and the outer polishing wheel assembly 3 rotates counterclockwise. At this time, the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3 rotate along the direction of travel of the metal wire 100, so that the relative movement between the inner polishing wheel assembly 2, the outer polishing wheel assembly 3 and the metal wire 100 is smoother, and the tiny unevenness on the surface of the metal wire 100 can be removed more evenly, thereby improving the surface smoothness of the metal wire 100. By intermittently changing the rotation direction of the inner polishing wheel assembly 2 and the outer polishing wheel assembly 3, the polishing quality of the surface of the metal wire 100 can be comprehensively improved.

[0030] Furthermore, multiple inner polishing wheel assemblies 2 are evenly distributed on the first annular track, and multiple outer polishing wheel assemblies 3 are evenly distributed on the second annular track.
