[0023] Furthermore, the lubricating powder box 9 is provided with an inlet 12 and an outlet 13 on both sides, and a limit block 14 is fixed on the inlet 12 and the outlet 13. The inside of the lubricating powder box 9 is filled with lubricating powder.

[0024] In this embodiment, the design of the lubricating powder box 9 allows the lubricating powder to be evenly applied to the steel wire body 8, thereby reducing the frictional resistance of the steel wire during the cold drawing process and improving the cold drawing efficiency.

[0025] Furthermore, the wire drawing die 10 is fixed to one side of the lubricating powder box 9, and the center of the wire drawing die 10 is provided with a wire drawing hole 15.

[0026] Furthermore, the cleaning mechanism includes a movable rotating block 16, which has a circular structure and a ring of brushes 17 on its inner wall. The movable rotating block 16 is mounted on one side of the output port of the wire drawing die 10 via a bearing.

[0027] Furthermore, a belt 18 is installed on the movable rotating block 16, and a drive wheel 19 is connected above the belt 18. A cleaning motor 20 is fixedly installed on one side of the drive wheel 19.

[0028] In this embodiment, the movable rotating block 16 is driven by the cleaning motor 20 and rotated by the belt 18. The brush 17 on the inner wall of the movable rotating block 16 cleans the steel wire body 8 and removes impurities and residues from the surface of the steel wire body 8.

[0029] Furthermore, a turntable 21 is installed at the bottom of the rotating drum 11, the turntable 21 is rotatably connected to the rotating drum 11, a rotating shaft 22 is fixedly installed at the bottom of the rotating drum 11, a small gear 23 is fixedly installed at the bottom of the rotating shaft 22, the traction motor 25 is located at the bottom of the processing table 3, a large gear 24 is connected to the traction motor 25, and the large gear 24 meshes with the small gear 23.

[0030] Furthermore, the cooling mechanism includes a fan 26 and a heat sink 27. The fan 26 is fixedly installed above the rotating cylinder 11, and the heat sink 27 is fixedly installed inside the rotating cylinder 11. A heat-conducting part 28 is fixedly provided on the inner wall of the rotating cylinder 11, and the heat sink 27 is connected to the heat-conducting part 28.

[0031] In this embodiment, the steel wire body 8 generates heat after being drawn by the wire drawing die 10 inside the rotating drum 11. To effectively dissipate heat, the cooling mechanism starts working. The fan 26 starts, generating a strong airflow that blows air onto the outer wall of the rotating drum 11, accelerating heat dissipation. The heat sink 27 increases the contact area with the air, further improving heat dissipation efficiency. In this way, the cooling mechanism ensures that the temperature of the steel wire body 8 remains stable during processing, avoiding quality problems caused by overheating.

[0032] Furthermore, the bottom of the rotating drum 11 is provided with an air outlet 29.

[0033] Working Principle: The steel wire body 8 enters the cold drawing mechanism 6 under the action of the conveying guide wheel 4. After being lubricated by the lubricating powder box 9, it enters the drawing die 10 for wire drawing. During the drawing process, the steel wire body 8 passes through the drawing hole 15. Due to the strong pulling force exerted by the drawing die 10 on the steel wire body 8, the steel wire body 8 will undergo plastic deformation, thereby changing its physical and mechanical properties. After the wire drawing is completed, the steel wire body 8 enters the cleaning mechanism. The movable rotating block 16 rotates under the drive of the cleaning motor 20 via the belt 18. The brush 17 on the inner wall of the movable rotating block 16 cleans the steel wire body 8, removing impurities and residues from its surface. Subsequently, the steel wire body 8 enters the traction mechanism 7. The rotating drum 11 rotates under the drive of the traction motor 25. Through the meshing transmission of the large gear 24 and the small gear 23, the traction operation of the steel wire body 8 is realized. During the traction process, the cooling mechanism cools the steel wire body 8. The fan 26 generates airflow, which carries away the heat generated by the steel wire body 8 through the heat sink 27 and the heat conduction part 28, and discharges it through the air outlet 29, thereby achieving effective cooling of the steel wire body 8. Finally, the steel wire body 8 is output through the output guide wheel 5, completing the entire cold drawing process.
