Method for eliminating texture structure of large-draw-ratio copper wire

Abstract

The invention provides a method for eliminating a texture structure of a large-draw-ratio copper wire, and relates to the technical field of copper wire processing. The method for eliminating the texture structure of the large-draw-ratio copper wire comprises the following specific steps that: step 1, a material is put into large drawing equipment; step 2, in a wire drawing process, the surface of the material is coated with a lubricating agent; step 3, during wire drawing, different powers are used for machining by observing changes of the material, high power is adopted for machining the material before the material is obviously processed and hardened, and low power is adopted for machining the material when the material is obviously processed and hardened; and step 4, after wire drawing is completed, the copper wire is subjected to a multi-section annealing process. High power is adopted before the material is obviously processed and hardened, and low power is adopted when the material is obviously processed and hardened, so that the error caused by material springback is improved under the condition that the material meets the processing requirement, and the drawing size of the copper wire is more accurate.

Description

technical field [0001] The invention relates to the technical field of copper wire processing, in particular to a method for eliminating the texture structure of a copper wire with a large draw ratio. Background technique [0002] In recent years, electronics and communication equipment have been developing towards precision and miniaturization, and equipment in the music field such as audio and earphones has also been continuously changing to be intelligent. Network technology and communication information industries are also developing in the direction of no delay. Real copper wire has more excellent performance, not only must have excellent machining performance, strength, toughness and fatigue strength, but also ensure that the copper wire has excellent electrical conductivity, weak signal interference, etc., to meet the current high electrical conductivity and signal The need for fidelity copper wires is imminent. [0003] At present, my country's copper wire processin...
