Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable processing, in particular to a stranding mechanism used for processing small-pitch soft aluminum stranded wires. Background Art
[0002] At present, the power distribution and transmission of the power system mainly relies on overhead transmission lines as the main carrier of power transmission. There are many types of overhead transmission lines, among which small-pitch soft aluminum stranded wires (commonly known as soft busbars) are mainly used for soft connections between electrical contacts in UHV substations.
[0003] Small pitch soft aluminum stranded wire has good flexibility due to its extremely small stranded wire pitch. It has a stable structure when bent, and has no deformation or cracks. Therefore, it has good product performance, high corona inception voltage, and low radio interference level, which is not achieved by general aluminum stranded wire. Its stranded wire pitch is small, and the ratio of the outer layer pitch to the diameter is less than 4.5. It allows a small bending radius and is soft. It does not deform or come out of the sleeve when making a small bend. It has a smooth and round surface and a stable structure, which is suitable for elastic soft connection. Therefore, since it was introduced to the power market in 2007, it has been well received by users (such as: Jinzhou, Nanjing, Chengdu, etc.). It is suitable for elastic soft connections between hardware fittings and conductors for high-voltage and ultra-high-voltage power grids, such as jumpers, extension joints, etc. It is especially suitable for elastic soft connections for hardware fittings of ultra-high voltage power grid projects.
[0004] However, the processing technology of fine-pitch soft aluminum stranded wire is difficult, and there is a phenomenon of gap separation during the production process. In addition, after high-temperature aging, the surface of the aluminum monofilament is astringent and has no oil film, which is prone to strand jumping during the production process. In response to the above problems, the present application provides a stranding mechanism for processing fine-pitch soft aluminum stranded wire, which can avoid the occurrence of gap separation and strand jumping during the stranding process. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a stranding mechanism for processing small-pitch soft aluminum stranded wires, which can effectively ensure the uniformity of force during the stranding process, avoid the occurrence of gap separation and strand jumping caused by uneven force on the outer layer of the stranded wire, and thus ensure the appearance quality of the stranded wire is qualified.
[0006] The technical solution adopted by the utility model is: a stranding mechanism for processing small-pitch soft aluminum stranded wires, including a wire-paying unit for paying out the stranded wires, a wire-dividing unit, a wire-stranding unit and a working platform for installing the above-mentioned units, the wire-dividing unit including a wire-dividing disk arranged corresponding to the wire-paying unit, the wire-dividing disk including a wire-dividing disk I, a wire-dividing disk II and a telescopic mechanism arranged therebetween, wire-dividing grooves are provided on the surfaces of the wire-dividing disks I and II at correspondingly equal intervals, and the wires are paid out by the wire-paying unit and then pass through the wire-dividing grooves to enter the wire-stranding unit for stranding.
[0007] Preferably, the wire-paying unit comprises a wire-paying bracket, a plurality of wire-paying rollers mounted on the wire-paying bracket, and a driving motor that drives the wire-paying rollers to pay off the wire.
[0008] Preferably, a slide rail is provided at a position of the working platform corresponding to the stranding unit, and the branching plate I, branching plate II and the stranding unit are slidably arranged on the slide rail to adjust the distance between the stranding unit and the branching unit.
[0009] Preferably, the branching disks I and II are made of nylon, the telescopic mechanism is made of a telescopic cylinder, the fixed end of the telescopic cylinder is mounted on the branching disk I, and the piston end of the telescopic cylinder is mounted on the branching disk II.
[0010] Preferably, the branching plate I and the branching plate II have the same structure, and are both formed by mortise and tenon-jointing two sections of the branching plate.
[0011] Beneficial effects of the utility model: The wire splitting unit of the utility model is composed of a wire splitting disc I, a wire splitting disc II and a telescopic mechanism between the two. By adjusting the distance between the two, the distance between the wire splitting unit and the wire twisting unit can be adjusted to avoid uneven force on the outer layer of the stranded wire due to too long a distance, thereby avoiding the occurrence of gap separation and strand skipping, ensuring the appearance quality is qualified and improving efficiency. Moreover, the extension of the wire splitting disc helps to control the center point of the stranded wire, avoiding a lot of production time wasted in finding the center point in the traditional stranding process, and greatly improving production efficiency.
