Pay-off spool for copper wire stranding process

Abstract

The invention discloses a pay-off spool for copper wire stranding process. The pay-off spool comprises a brush disk and a plurality of resin thin lines. The brush disk is provided with a fixation hole in the center; the plurality of resin thin lines extend out of the brush disk along the radial direction of the brush disk; the upper surface of the brush disk is bonded with a circular press plate concentric with the brush disk; the press plate covers a part of the resin thin lines; the lower surface of the press plate is provided with a circular groove; and bend sections are arranged in the circular groove. The flexibility of the plurality of resin thin lines extending outwards on the brush disk is utilized to enable copper wires to make direct contact with the resin thin lines before separating from a reel, so that operation amplitude of the copper wires is allowed to be enlarged when separating from the reel, the resin thin lines are allowed to return to initial positions due to elastic deformation return function of the resin thin lines after having a certain amplitude upwards with the copper wires, and meanwhile, abrasion loss caused when the copper wires make contact with the resin thin lines can be ignored, that is, the copper wires can be separated from the reel conveniently and quickly, and meanwhile, loss of the copper wires is reduced.

Description

Technical field [0001] The invention relates to the field of copper stranded wire processing, in particular to a pay-off reel used for the copper wire stranding process. Background technique [0002] The stranding principle of copper stranded wire is as follows. When the copper wire passes through the twisting bow on the stranding machine, the twisting bow moves in a circular motion, so that each single copper wire is spirally wound together, and the twisted copper wire is a single copper Where the amount of wire is the largest, copper wires of different specifications and different numbers are twisted together according to a certain arrangement sequence and lay length to become a conductor with a larger diameter. This stranded conductor is better than a single conductor of the same diameter. The copper wire is soft, and the bending performance of the processed wire is better. [0003] In the process of copper stranded wire processing, that is, the twisting process of copper wire,...

AI Technical Summary

Problems solved by technology

[0003] In the process of copper stranded wire processing, that is, in the copper wire stranding process, the turns of copper wire are drawn and twisted together in a certain direction and according to certain rules to form a whole twisted core, but the copper When the wire is removed from the drum, it is easy to collide or rub against the wall of the drum, and even cause the copper wire to break in severe cases, resulting in large economic losses
