Description

Technical Field

[0001] The utility model relates to the technical field of copper-aluminum composite bar production, in particular to copper-aluminum composite bar production equipment. Background Art

[0002] In the metalworking field, copper-aluminum composite bars, a material that combines the excellent conductivity of copper with the lightweight and high strength of aluminum, have been widely used in the power industry in recent years. However, existing copper-aluminum composite bar production equipment faces a series of technical challenges during the production process, particularly during the cooling process where the aluminum castings discharge molten aluminum and the copper castings discharge molten copper, wrapping the molten copper around the aluminum to form the composite bar. In particular, the precise control of the solidification process of the molten aluminum and copper has become a bottleneck limiting product quality and production efficiency.

[0003] In the manufacturing process of copper-aluminum composite busbars, the solidification process of the molten aluminum and copper directly impacts the quality and performance of the final product. Traditional equipment often utilizes a fixed-mode cooling system, which makes it difficult to precisely control the cooling rates of the molten aluminum and copper. This results in poor timing of the solidification of the molten copper and aluminum during the cooling process, triggering a series of chain reactions. On the one hand, insufficient cooling prevents the molten copper from fully encapsulating the molten aluminum, compromising the mechanical strength and electrical conductivity of the composite busbar. On the other hand, excessive cooling can cause the molten aluminum and copper to solidify prematurely, even leading to blockages in the flow channels, seriously impacting production continuity and yield.

[0004] Of particular note, improper control of the solidification of the molten aluminum and copper during the cooling process can easily lead to the serious problem of flow channel blockage. When the cooling rate is too high, the molten aluminum and copper solidify before reaching the desired position. This not only hinders the subsequent flow of the liquid but also forms air holes or areas of insufficient fusion within the composite row, significantly reducing product quality. More seriously, frequent flow channel blockages force frequent production line shutdowns for cleaning, significantly reducing production efficiency and increasing maintenance costs, directly impacting the company's economic benefits.

[0005] Inaccurate cooling control also creates a conflict between production efficiency and product quality. To ensure product quality, manufacturers are forced to sacrifice some production speed by slowing the cooling rate to prevent flow channel blockage. However, this approach not only reduces production efficiency but also increases energy consumption due to extended cooling time, further increasing production costs. Conversely, if high-speed production is pursued while neglecting cooling control accuracy, product quality cannot be guaranteed, ultimately affecting market competitiveness.

[0006] Therefore, how to provide a copper-aluminum composite bar production equipment is a problem that those skilled in the art urgently need to solve. Utility Model Content
