AI Technical Summary
Existing titanium and titanium alloy fiber drawing dies cannot simultaneously achieve high strength, high wear resistance, and high thermal conductivity under high temperature and high pressure, resulting in severe adhesive wear and difficulty in dissipating frictional heat, which affects production efficiency and cost.
The wire drawing die is made of copper-steel composite material, with a high-strength steel layer providing support and a copper-based working layer that has high thermal conductivity and low friction. It is combined with hard wear-resistant particles and solid lubricant and is prepared by processes such as powder metallurgy or hot isostatic pressing to form an embedded or integral composite structure.
It significantly reduces the temperature of the mold working area, reduces the adhesive wear of titanium wire, extends the mold life, improves the surface finish and dimensional accuracy of the fiber, and reduces energy consumption and manufacturing costs.
