Description

technical field [0001] The invention relates to a copper alloy flat wire processing equipment, in particular to a composite processing equipment with high precision. Background technique [0002] Copper alloy flat wire is mainly used in the production of electrical connector components and luggage zipper wires. The processing technology of the traditional copper alloy flat wire is that the round wire billet passes through the wire drawing machine, annealing furnace, cooling device, pickling, wire drawing machine, flattening machine, annealing furnace, cooling device and pickling in turn, and finally through the finished product drawing machine. . The specific process is as follows: first, the copper alloy round wire blank is drawn into a thick wire by a wire drawing machine. During the rough drawing process, the wire rod is greatly deformed and difficult to process later due to work hardening. Therefore, the thick wire needs to be placed in an annealing furnace for It unde...

AI Technical Summary

Problems solved by technology

[0003] In the whole processing process, because the flat wire is formed from rough rolling, rough drawing, and then fine drawing to the finished product, the process is too long and complicated, the production cost is high, and the labor intensity is high.

In addition, manual operation during the production process will easily cause defects on the surface of the copper wire, making the surface of the finished copper alloy flat wire blurred and scratched to form grooves, which will affect the later electroplating and surface quality

In addition, there is a pickling process, which seriously pollutes the environment.
