Aluminum molded wire turnover prevention device

Abstract

The invention discloses an aluminum molded wire turnover prevention device which comprises a wire stranding disc, wherein a hinged shaft hole is formed in the center of the wire stranding disc, a wire passing hole is formed in the wire stranding disc in a penetrating mode, a supporting plate perpendicular to the surface of the wire stranding disc is further installed on the wire stranding disc, a guide wheel and two pressing wheels are installed on the supporting plate in a hinged mode, the two pressing wheels are located on one side of the guide wheel, the circumferential side surfaces of the guide wheel and the pressing wheels right face the wire passing hole, the circumferential side edge of the guide wheel is provided with a wire containing groove with the inverted-trapezoid-shaped section, a trapezoid aluminum molded wire penetrates through the wire passing hole and then is pressed in the inverted-trapezoid-shaped wire containing groove through one guide wheel and the two pressing wheels, it is guaranteed that the trapezoid aluminum molded wire is stable and does not turn over for a long time, the structure is simple, and the turnover prevention effect is good.

Description

technical field [0001] The invention relates to the technical field of electric wire and cable manufacturing, in particular to an aluminum-shaped wire anti-turnover device. Background technique [0002] In the production and use of overhead conductors, most of them are circular single wires. With the development of economy, power grid users put forward higher and higher requirements for the performance indicators of overhead conductors, so people invented a trapezoidal aluminum wire later. like figure 1 As shown, its cross-section is trapezoidal, and multiple trapezoidal aluminum-shaped wires are twisted to make aluminum-shaped wires. Compared with ordinary round aluminum wires, this aluminum-shaped wire has a smaller outer diameter, which can effectively reduce the size of the connecting fittings and reduce the size of the fittings. Low cost, small wind resistance area, can reduce the risk of line galloping and icing, so it is more and more used in line engineering. [00...

AI Technical Summary

Problems solved by technology

[0003] However, in the process of producing aluminum-shaped wire conductors, domestic manufacturers generally encounter the problem of trapezoidal aluminum-shaped wire turning over, which affects production quality and efficiency. In severe cases, it even causes trapezoidal aluminum-shaped wires to break, resulting in product scrapping

[0004] At present, the aluminum-shaped wire conductors produced by most domestic manufacturers still prevent the trapezoidal aluminum-shaped wire from turning over through the mold. If the wire turns over, there is no guarantee that the trapezoidal aluminum wire will not turn over for a long time
