Description

Technical Field

[0001] The invention relates to the technical field of copper strip production and processing, and in particular to a copper strip shape stress release device and a use method thereof. Background Art

[0002] Copper strip has the advantages of high conductivity, high thermal conductivity, good corrosion resistance and processing performance. It is widely used in many fields such as electrical, electronic, construction, decoration, etc. The material is not only beautiful, but also has good corrosion resistance and durability. In the construction field, copper strip is used to make decorative materials such as roofs and walls. It is not only beautiful, but also has good corrosion resistance and durability. With the technological development of electronic information, new energy vehicles, connectors and other fields, higher requirements are put forward on the surface quality, thickness tolerance and other properties of copper strip. Therefore, research on the shape control of copper strip for composite materials is of great significance to improving the application field of copper strip and increasing the added value of products.

[0003] The production and manufacturing process of copper strip involves multiple links. First, high-quality pure copper raw materials are selected, and the initial copper billet is formed through smelting, casting and other processes. Then, the copper billet is gradually pressed into the required thickness of copper strip through multiple rolling processes. During the rolling process, it is necessary to strictly control parameters such as rolling temperature, speed and reduction to ensure the dimensional accuracy and surface quality of the copper strip. Finally, after annealing, pickling and other treatments, the performance and quality of the copper strip are further improved.

[0004] In the current prior art, after the rolling step of copper strip production, it is necessary to pass through a heating furnace for heating, and then slowly cool it after being heated to a certain temperature range, and release the stress of the copper strip through multiple annealing processes. However, using multiple processes for stress release not only makes the labor intensity of the staff greater, but also requires a long time for each annealing, which not only affects the efficiency of copper strip production, but also increases the labor cost of copper strip production. Therefore, a copper strip stress release device and a use method are proposed to solve the above problems. Summary of the invention
