Novel process for calendering copper wire

Abstract

The invention relates to a novel process for calendering a copper wire. The novel process comprises the following steps of: preliminarily pressing the copper wire into flat copper, and then heating the flat copper to be at recrystallization temperature; pressing the flat copper again to obtain finally-shaped flat copper; and pressing and grinding the flat copper coated with a grinding paste by using a pressure mechanism. After the copper wire deforms to form the flat copper, the flat copper is heated to be at the recrystallization temperature of the flat copper so as to improve the plasticity of the flat copper, and the pressure mechanism presses and grinds the flat copper coated with the grinding paste to facilitate the improvement of the degree of finish of the outer surface of finally-processed flat copper; and the novel process is simple and feasible and is low in cost.

Description

technical field

[0001] The invention relates to a copper wire flattening process flow. Background technique

[0002] At present, the copper wire is generally flattened by a cold rolling mill, and then the flattened copper wire is coiled onto a take-up reel. However, the flat copper processed by the cold rolling mill is generally uneven, twisted and prone to broken wires, which is not conducive to the application of flat copper. Contents of the invention

[0003] In order to overcome the disadvantages of the existing copper wire flattening process that the processed flat copper is uneven, twisted and easy to break, the present invention provides a new copper wire rolling process, which can produce The flat copper can overcome the above shortcomings, and the process flow is simple.

[0004] The technical solution adopted by the present invention to solve its technical problems is: the new copper wire rolling process comprises the following steps:
