The working principle of the utility model is as follows: the utility model can be used with a wire drawing machine or a current traction machine, the wire 8 is pulled to move by the wire drawing machine or the current traction machine, and when the wire is drawn, the plunger 311 is clamped with the clamping piece 3717 on the first wire brushing unit 371 and the second wire brushing unit 372, so that the wire is conveniently drawn. Referring to fig. 1, the wire rod transmission direction is from left to right, and the metal wire rod 8 straightens the wire rod through the straightening mechanism 1, so that the wire rod entering the wire brushing mechanism 3 keeps a straight state and plays a role in stabilizing the wire rod 8, and meanwhile, the limiting component 8 has a limiting function, so that the wire rod is positioned at the center of the first rotary table 3 and is positioned at the central axis position in the wire brushing cavity. When the wire brushing operation is performed, the plunger 311 is pulled up, the plunger 311 is separated from the clamping piece 3717, the motor drives the two groups of wire brushing mechanisms 3 to rotate at a high speed of 360 degrees to form centrifugal force, the counterweight 3712 also forms pressure in the rotating process, and accordingly the first wire brushing unit 371 and the second wire brushing unit 372 use the shaft hole 3719 as a pivot point to enable the first wire brushing head 3715 to compress the wire 8, the wire 8 at the center of the wire brushing roller is continuously brushed, and meanwhile, the limiting component 38 also performs wire brushing operation to remove surface oxidation layers, rust spots and part of surface pits.

In the above process, the wire head tension needs to be adjusted due to the difference of the material and diameter of the processed wire 8, the first link 33 and the second link 34 are rotated left and right, and the driving spring 312 adjusts the wire pressure of the first wire brushing unit 371 and the second wire brushing unit 372 accordingly. Because the rotation speed of the wire head on the wire brushing barrel is different, the pressure on the surface of the wire 8 is different due to different centrifugal forces, the counterweight 3712 is arranged, and the counterweight 3712 with proper weight can be selected to play a role in centrifugal balance, so that the pressure difference factors caused by different rotation speeds can be eliminated.
