[0002] A wire drawing die refers to a tool that, during the metal pressure processing process, forces metal to pass through the die under the action of external force. The cross-sectional area of the metal is compressed, and the required cross-sectional area shape and size are obtained. As the aperture of wire drawing decreases, friction and wear occur faster, and a diamond coating with high hardness, high wear resistance, low friction coefficient, and high surface finish is required.

[0003] During the use of existing dies, when products of different models, shapes, and sizes need to be produced, both the die sleeve and the inner die need to be replaced together, resulting in high costs and reduced practicality. Moreover, the heat generated during wire drawing is not easily discharged and cooled, affecting the service life and the wire drawing quality of the material.
