Description

Technical Field

[0001] The invention relates to the technical field of soft copper conductor processing, in particular to a soft copper conductor pressing die. Background Art

[0002] A soft copper conductor compression die is a die used to process soft copper conductors, usually in the production process of cables, wires or other copper electrical components. The function of the compression die is to press or shape the copper conductor under high pressure to ensure that it has the required mechanical properties, dimensional accuracy and surface quality.

[0003] The compaction of copper conductors is a process that compresses or shapes the copper conductors in a mold under high pressure to achieve the required size, shape and mechanical properties. The compaction process not only affects the physical properties of the conductor, but also has an important impact on its subsequent electrical properties and processing quality.

[0004] The problems existing in the existing soft copper conductor pressing molds mainly include short mold life, severe wear, and difficulty in maintaining stable processing accuracy. Since the soft copper material has high adhesion and low hardness, it is easy to bond or rub with the mold surface during the pressing process, causing the mold surface to gradually wear or deform, thereby affecting the processing quality and product consistency. In addition, the soft copper conductor may produce a large deformation under high-pressure pressing, making it difficult for the mold design to meet the production requirements of products of different specifications, increasing production costs and maintenance difficulties. For this reason, a new type of soft copper conductor pressing mold is provided to solve the above problems. Summary of the invention
