Production technology for hollow abnormal-shape electric anaerobic copper plate

2012 
The invention provides a production technology for a hollow abnormal-shape electric anaerobic copper plate, comprising the following technologies of: upwards leading a continuous anaerobic copper strip blank, carrying out cold rolling, annealing, brushing in an acid washing way, carrying out primary cold-rolling forming (a cold rolling method), straightening, testing, and packing. Compared with the prior art, the production technology has the following advantages that 1) the production technology is high in production efficiency, and the cold rolling technology primarily and coldly rolls double rows of continuous electric convex hulls through a specific abnormal-shape hole pattern, so that the primary forming can be carried out; 2) the product is regular in appearance shape, the electric convex hulls which are primarily formed by the cold rolling method and the cross-section shapes are regular in shapes, and are stable and even in size, and the defect problem such as the 'bamboo joints' shape caused by the repeated press forming in the conventional technology can be avoided; 3) the production technology is short in technological process, is low in cost, and is directly and coldly rolled into stripe materials as required by upwards leading the continuously-cast anaerobic copper strip blank, the primary cold-rolling forming can be carried out after the thermal treatment, the higher-cost procedures such as the heating and the hot-rolling cogging can be eliminated, the technology can be optimized, and the production cost can be reduced; and 4) the product is good in product quality, and has the characteristics of being high in purity, low in oxygen content, high in electric conductivity, and good in surface quality.
