Continuous extrusion production process and production equipment of copper-coated aluminum busbar

Abstract

The invention provides a continuous extrusion production process of a copper-coated aluminum busbar. The process comprises the following steps in sequence: (1) an aluminum raw material is fed into a continuous extruder; and an aluminum material is continuously extruded out in a discharge port of the continuous extruder; (2) the aluminum material is coated by a copper strip, and is welded with the copper strip to obtain a copper-coated aluminum blank; and (3) the copper-coated aluminum blank is rolled to obtain a copper-coated aluminum profile. The production process can continuously produce the copper-coated aluminum profile through a long flow, destroys a traditional short-flow preparation concept of a copper-coated aluminum composite material, and largely simplifies the steps to reduce the investment quantity and repeated investment quantity of production equipment so as to effectively reduce the production cost.

Description

technical field [0001] The invention relates to the field of manufacturing copper-clad aluminum bars, in particular to a copper-clad aluminum bar continuous extrusion production process and production equipment. Background technique [0002] my country's "863 Program" included "Study on the subject of short-process and efficient preparation and processing of high-performance copper-clad aluminum composite conductor materials" as a goal-oriented key subject. Copper-clad aluminum busbar is a bimetal with aluminum as the matrix and copper-coated outer layer. It combines the high-quality electrical conductivity of aluminum, low-cost energy, and the high chemical stability and low contact resistance of copper. A new type of conductor material, which clads copper with excellent electrical properties on low-density aluminum to form a copper-clad aluminum composite material, which effectively reduces costs while maintaining excellent performance.

Therefore, the above process will inevitably lead to the need for two-part manufacturing equipment, and its investment cost is obviously high, and in the two-stage manufacturing process, it is inevitable to invest in auxiliary equipment (for removing oil stains, oxide layers, cleaning, etc.), repeated Use of energy (i.e. reheating), process energy loss (removal of oil, oxide layers, cleaning, etc.), and generation of process waste (broken ends and stretching process laps, etc.)
