Analysis of Key Technologies for Copper Drawing Machine

Among the many key technologies of copper wire drawing machines, wire drawing mold technology plays a crucial role. Wire drawing molds are generally made of materials such as hard alloys, and the shape and surface smoothness of their internal cavities directly affect the quality of copper wires. A high-precision mold cavity can ensure that the copper wire is subjected to uniform force during the drawing process, thereby obtaining a stable diameter and good surface quality. For example, advanced wire drawing molds can control the error of copper wire diameter within a very small range through precision machining.

Meanwhile, the tension control system is also crucial. The appropriate tension is the key to ensuring the quality and production continuity of copper wire during the drawing process. If the tension is too high, the copper wire is prone to breakage; If the tension is too low, it can cause problems such as looseness and lack of tightness in the copper wire. At present, many copper wire drawing machines adopt advanced sensors and automation control systems, which can monitor and adjust tension in real time to ensure the stability of the production process.

Another key technology is annealing process. During the drawing process, copper wire will undergo work hardening due to plastic deformation, which affects its subsequent processing and usage performance. Annealing process can eliminate this hardening phenomenon and restore the toughness and conductivity of copper wire. Advanced annealing technology adopts precise temperature control and atmosphere protection to ensure the uniformity and stability of the annealing effect.
