Copper cladding aluminium wire, copper cladding aluminium pipe production process and its equipment

Abstract

This invention involves a copper coated aluminium wire, copper coated aluminum tubes production technology and equipment. It is the preferred production technology and equipment for Copper aluminium wire producing. This invention address the problems of existing technologies, provide a copper coated aluminium wire, copper coated aluminum tubes production technology and equipment, manufacturing process simple and reasonable, copper savings, reduce production processes significantly shorten product time to ensure that the copper coated aluminium wire the copper layer uniformity, and better meet both metallurgical combination of stable quality, high production efficiency, significantly reduce production costs of copper coated aluminium wire(tube) production technology. Drawing not only help reduce the number of metallurgical combine to achieve rapid product quality and help the stability at the same time in the past to resolve the metallurgical combine before tensile quality and difficult to control, simplify the process to improve the efficiency of production and the need to save burr edge copper, in particular when processing large diameter, the more obvious improve material utilization, significantly lower manufacturing costs, in addition to wide application of the different diameter sizes processing, but also processing copper coated aluminum tubes, and many other advantages and positive results, and it also has been proved by testing.

Description

technical field [0001] The invention relates to a composite material production technology, in particular to a copper-clad aluminum wire, copper-clad aluminum tube production process and equipment thereof. It is the preferred production process and equipment for the production of copper-clad aluminum wire and copper-clad aluminum tube. Background technique [0002] As we all know, copper-clad aluminum wire and copper-clad aluminum tube are copper-aluminum composite materials. The above-mentioned products have the advantages of light weight of aluminum, electrical conductivity of copper, and good anti-corrosion performance. They are widely used in radio frequency cables, electromagnetic wires, and braided wires. Aluminum shielded wires, power cords and other products. Reduce costs and save resources. Copper-clad aluminum tubes can be used for the suspension of radio frequency cables, and can also be used as condenser tubes for air conditioners and other products. Copper-cla...

AI Technical Summary

Problems solved by technology

However, there are also problems such as multiple stretches after welding to achieve metallurgical bonding, which not only takes time and labor, but also increases production costs.

And because of the unsatisfactory defects such as many times of stretch molding and easy damage of the surface

In particular, the total deformation must reach more than 87% to meet the requirements of metallurgical bonding. Therefore, it is difficult to control the stretching quality before metallurgical bonding, which increases the difficulty of the stretching process.

If it cannot be solved as soon as possible, it will affect the quality and stability of the copper-clad aluminum wire. This has aroused serious concern from relevant people in the industry, and invested scientific and technological personnel and financial resources. However, no relevant reports on successful solutions have been seen so far.
