Background

Drawing is a plastic forming process in which a metal blank is pulled through a die opening to obtain an article having the same size and shape as the die opening. The drawing is one of the main production methods of pipes, bars, profiles and wires, the copper bar is a large-current conductive product, is suitable for electrical engineering of high and low voltage electrical appliances, power distribution equipment and the like, and is also widely used for super-large current electrolytic smelting engineering of metal smelting, electrochemical plating, chemical caustic soda and the like. The copper bar can be divided into a common copper bar and a special-shaped copper bar according to the difference of the cross-sectional shapes of the copper bar: the section of the common copper bar is rectangular or square, while the section of the special-shaped copper bar is irregular in shape such as L-shaped, T-shaped, trapezoid and the like. Due to the requirement of industrial production, the demand of the special-shaped copper bars is more and more large.
