Problems solved by technology

The position and distance between the twisted bow and the magnetic ring are fixed, and each magnetic ring is connected into a section of string, so that it does not feel very smooth when running, which will greatly affect the roundness of the twisted copper wire.

Embodiment 1

[0009] A device for improving the roundness of conductor stranding, including a twist bow 1, on which a number of magnetic eyes 2 are arranged; the radial distance between the magnetic eyes at both ends of the twist bow and the twist bow is the largest, and the magnetic eyes in the middle are the largest. The radial distance between the eye and the twisted bow is gradually reduced, and the distance between the magnetic eyes is gradually reduced.

[0010] The above device is mainly used in 500-type stranding machine, suitable for twisting small sections (≤1.25mm 2 )conductor. The whole line will become smoother, and the whole curve will become close to the shape of the "fastest curve", that is, the "cycloid", which will make the whole line run more smoothly, and at the same time, the roundness of the twisted wire can also be in the best state .

Embodiment 2

[0013] A device for improving the roundness of conductor stranding, comprising a twist bow 1, guide wheels 3 are arranged at both ends of the twist bow 1; the radial distance of the guide wheels 3 from the twist bow 1 is greater than the distance from the magnetic eye 2 The radial distance of the twist bow 1; the radial distance between the magnetic eyes at both ends of the twist bow and the twist bow is the largest, and the radial distance between the magnetic eyes and the twist bow gradually decreases toward the middle, and the distance between the magnetic eyes gradually decreases.

[0014] The above device is mainly used in the 630 type stranding machine, which is suitable for stranding large cross-sections (>1.25mm 2 ) conductor to ensure that the large square line reaches a hollow state.

[0015] A method for improving the roundness of conductor stranding. When the speed of the 630-type stranding machine is 800-1000rpm, the entire copper wire a runs through the guide whe...

Abstract

A device for improving the roundness of conductor stranding, including a twist bow, on which several magnetic eyes are arranged; the radial distance between the magnetic eyes at the two ends of the twist bow and the twist bow is the largest, and in the middle, the magnetic eyes and the twist bow The radial distance of the bow is gradually reduced, and the distance between the magnetic eyes is gradually reduced. In the device of the present invention, the hollow state of the copper wire is kept very well, and the quality of the twisted wire is the highest.

Description

technical field [0001] The invention belongs to the field of cable processing, and in particular relates to a device and method for improving the roundness of conductor stranding. Background technique [0002] The conductor stranded wire is realized by the twisted single wire rotating around the axis of the stranded wire at an equal angular velocity and the stranded wire moving forward at a uniform speed. The single copper wire on the pay-off reel passes through the distribution reel through two to three rows of guide wheels, and then passes through Pass the twisted bow to the take-up reel to take up the line. In the processing of small round wire conductor cross-section wires, stranded wires are generally divided into two types: regular stranded and irregular stranded (ie bundle stranded). Regular twisting means that the single wire takes the center line of the twisted wire as the axis, and is layered and orderly twisted around it. The directions of adjacent twisted layers...
