Description

Technical Field

[0001] The utility model relates to the technical field of oxygen-free copper wire production equipment, in particular to a high-efficiency wire drawing device for oxygen-free copper wire production. Background Art

[0002] Copper has high electrical and thermal conductivity, good weldability, excellent plasticity and ductility, excellent cold workability, and is non-magnetic. Dispersed oxygen-free copper overcomes the shortcomings of low yield strength after annealing and poor creep resistance at high temperatures, boasting high-temperature, high-strength, and high thermal conductivity properties, earning it high attention from electronic materials experts. Copper and its alloys are widely used in the electronics industry. In vacuum electronic devices, oxygen-free copper ranks first among the seven major structural materials used in this field. Oxygen-free copper products are primarily used in the electronics industry and are often made into oxygen-free copper plates, strips, and wires.

[0003] Publication No. CN110947789B discloses a high-efficiency wire drawing device for producing oxygen-free copper wire. This device can effectively clean dust adhering to the surface of the oxygen-free copper wire, namely, it can moisten the oxygen-free copper wire, which acts to fuse the dust on the surface of the oxygen-free copper wire and prevent dust from floating. However, during the wire drawing process, the copper wire is wrapped around a receiving roller after production. During the drawing process, the diameter of the copper wire on the receiving roller surface decreases during processing, resulting in the copper wire being easily damaged during the drawing process. Therefore, we propose a high-efficiency wire drawing device for producing oxygen-free copper wire. Utility Model Content
