Embodiment 1

[0021] The copper braided wire manufacturing method is as follows:

[0022] Step 1. Pull the polished and cleaned red copper into an oxygen-free copper rod with a diameter of 6mm;

[0023] Step 2. Pull the oxygen-free copper rod with a diameter of 6mm into an inner wire with a diameter of 2.6mm;

[0024] Step 3. The inner withdrawing wire with a diameter of 2.6mm is first drawn into thick copper wire with a diameter of 1.0mm through the first wire drawing machine; then the thick copper wire with a diameter of 1.0mm is drawn into a diameter of 0.2 mm fine copper wire; and then through the third wire drawing machine, the thin copper wire with a diameter of 0.2mm is drawn into an ultra-fine copper wire with a diameter of 0.05mm;

[0025] Step 4. Twist several (such as 200) ultra-fine copper wire bundles with a diameter of 0.05mm into a strand according to customer requirements, and then compound and twist several strands (such as 10) into a composite blank wire;

Abstract

The invention relates to a copper braided wire manufacturing method, including the following steps: drawing polished and cleaned red copper into an oxygen-free copper rod, drawing the oxygen-free copper rod into an internal annealing wire, drawing the internal annealing wire into superfine copper wires through multiple wire drawing machines, twisting the superfine copper wires into a stranded wire, and then combining and twisting the stranded wire into a composite blank wire; and annealing the composite blank wire to obtain a composite wire, braiding the composite wire on a braiding machine toform a semi-finished wire, and removing the oil stain on the surface of the semi-finished wire by using a centrifugal dryer to manufacture a copper braided wire. Through the optimization design of anexisting copper braided wire manufacturing process, a finished product manufactured by using the copper braided wire manufacturing method disclosed by the invention has a strong anti-oxidation ability, and the finished product is not easy to blacken, is good in tensile strength and high in product quality, and has high application values.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a method for manufacturing copper braided wires. Background technique [0002] Copper braided wire is made of oxygen-free copper or low-oxygen copper wire. The diameter of copper wire is divided into 0.05mm / 0.06mm / 0.08mm / 0.10mm / 0.12mm / 0.15mm / 0.20mm. The more flexible the product, the more resistant to bending. During the processing, it is toughened to make the product soft, bright and neat in appearance. [0003] Copper braided wires can be used for transformer installation, high and low voltage switchgear cabinets, vacuum appliances, closed busbars, generators and busbars, rectifier equipment, connections between rectifier cabinets and isolating switches, and connections between busbars. It can improve the conductivity, adjust the installation error of the equipment, and at the same time play the role of (shock absorption) work compensation, and facilitate the t...
