Embodiment Construction

[0011] A method for continuously manufacturing copper-clad aluminum busbars by cladding welding and rolling, in which the process of copper strips cladding aluminum rods is continuously completed under gas protection, and the specific manufacturing method of the copper-clad aluminum rectangular busbars includes the following steps:

[0012] A. Cleaning: Use mechanical methods to degrease and brush the surfaces of copper strips and aluminum rods;

[0013] B. Production of busbar blanks: According to the size of the finished product, the size of the copper-clad aluminum blanks is designed and calculated, and the copper strips are wrapped along the long axis of the aluminum rods with special tape-winding equipment. Under the protection of argon gas, the argon arc welding machine The butt joint surface of the copper strip is welded to make a copper-clad aluminum blank;

[0014] C. Cold drawing diameter reduction: remove the oxide skin of the copper strip after welding, and use con...

Abstract

The invention relates to a method for manufacturing copper clad aluminum bus bar through clad welding and rolling, which is characterized in that a process of copper strips cladding copper bar is continuously performed under gas shielding, the specific method comprises the following steps: cleaning; bus bar blank manufacturing; diameter reducing by cold drawing; stretching by heating and roll compacting and annealing. The invention has the advantages that conductors for securing metallurgical combined entirety are formed on the two metal interfaces through diffusing heat treatment of two materials and one or two elongating rolling. By adopting clad welding, diameter reducing, heating and roll compacting continuous finishing process, the production rate is improved greatly, the process time is shortened; and the quality is ensured. Because preprocessing mechanical scrubbing is finished during clad welding, the brush graining process is simplified, thereby facilitating dust treatment. By adopting the continuous production, the requirements of users for long line can be met.

Description

technical field [0001] The invention belongs to a bus bar of an electric power system, in particular to a method for continuously manufacturing a copper-clad aluminum bus bar by cladding welding and rolling. Background technique [0002] Copper bus bars are widely used in power supply systems such as low, medium and high voltage distributors, switch cabinets, control panels, bus ducts, vacuum switchgear and generator sets, rectifiers, transformers, motor windings, bimetal joints, and crane rails. It has the advantages of good electrical conductivity, large carrying capacity, small resistivity, high mechanical strength, and good corrosion resistance. But at the same time, there are also disadvantages such as high cost, large unit weight, and lack of resources, so the application is greatly limited; although the cost of pure aluminum busbars is low, it has a small carrying capacity, is easy to close corrosion, and is easy to hydrogenate at the joints. The performance is satisf...
