Wire drawing and paying-off structure

Abstract

The invention discloses a wire-drawing and unwinding structure, including a brush plate and a plurality of thin resin wires, a fixing hole is opened in the middle of the brush plate, and a plurality of thin resin wires extend outwards of the brush plate along the radial direction of the brush plate. The upper surface of the brush disc is bonded with a concentric and ring-shaped lower pressing plate, the lower pressing plate partially covers the thin resin lines, the lower surface of the lower pressing plate is provided with an annular groove, and the curved section is placed in the annular groove. The present invention utilizes the flexibility of a plurality of resin thin wires extending outward on the brush disc to make the copper wires directly contact with the resin thin wires before detaching from the reel, so that the running range of the copper wires when detached from the reel increases, The thin resin wire will return to its original position due to its own elastic deformation recovery after a certain swing upward with the copper wire. At the same time, the amount of wear caused by the contact between the copper wire and the thin resin wire is negligible, which is convenient for the copper wire. While quickly detaching from the drum, the wear of the copper wire is reduced.

Description

technical field [0001] The invention relates to the field of copper stranded wire processing, in particular to a wire drawing and unwinding structure. Background technique [0002] The twisting principle of the copper stranded wire is as follows. When the copper wire passes through the twisting bow on the twisting machine, the twisting bow passes through the circular motion, so that the individual copper wires are helically wound together, and the twisted copper wire is a single copper wire. Where the maximum amount of wire is used, copper wires of different specifications and different numbers are twisted together in a certain order and lay length to become a conductor with a larger diameter. The copper wire is soft, and the wires processed by it have better bending performance. [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 accordi...

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
