The warping of copper bars after stamping is caused by internal stress imbalance, which can affect the quality and effectiveness of the copper bars. To solve this problem, leveling processing can be carried out, which involves mechanical or heat treatment to restore the copper strip to a balanced state, eliminate internal stress, and achieve a flat effect.
The specific leveling processing methods include mechanical leveling and heat treatment leveling. Mechanical leveling is processed through rolling, stretching, and bending, which can make the surface of the copper strip flat, but the effect is not significant for large areas of warping. Heat treatment leveling is achieved by heating the copper strip to a certain temperature and then rapidly cooling to adjust internal stress, which can effectively eliminate the warping problem of the copper strip.
Leveling processing is an effective solution to the problem of warping of copper bars after stamping, which can improve the quality and effectiveness of copper bars.
