Drawing is a processing technology that plastically deforms metal materials at room temperature and plays an important role in the production process of cold heading steel wire.

[0003] In the prior art, when using the device, one end of the cold-headed steel wire is first fixed to the clamping device. Then, the power transmission component begins to apply tension, causing the steel wire to gradually pass through the drawing die. Since the aperture of the drawing die is smaller than the original diameter of the steel wire, the steel wire is subjected to the dual effects of compression and stretching when passing through the die, resulting in plastic deformation. When the steel wire enters the die for drawing, heat is generated on the surface of the steel wire during the drawing process, causing it to deform during drawing, affecting the drawing effect and failing to achieve the required steel wire diameter. Therefore, it is necessary to improve a drawing tool for cold-headed steel wire processing to solve the above problems. Utility Model Content
