Abstract

The invention discloses a twisting apparatus for a communication power supply flexible cable. The efficient twisting apparatus comprises two groups of pay-off racks, two groups of tension rods, a front draft gear, a positioning apparatus, a plastic extruding machine, a cooling water bath and a take-up stand, wherein the positioning apparatus comprises a fixed frame, two arc-shaped guide wheel mechanisms, two planar guide wheel mechanisms and a cable collecting base, wherein a cable collecting through hole is formed in the center of the cable collecting base; the fixed frame comprises a supporting frame and a base plate; a first mounting groove and a second mounting groove are formed in one end of the base plate in parallel in a direction perpendicular to a trending direction; the wire collecting base is mounted at the other end of the base plate; the second mounting groove is positioned between the first mounting groove and the wire collecting base; the arc-shaped guide wheel mechanisms comprise arch-shaped circular wheels, wherein the end planes of the arc-shaped circular wheels are arc-shaped planes, and the arc-shaped circular wheels are arranged parallel to the base plate; and the planar guide wheel mechanisms comprises planar circular wheels, wherein the end planes of the planar circular wheels are planar, and the planar circular wheels are arranged parallel to the base plate. The problem that the existing communication power supply flexible cable is not circular and tidy is solved by the twisting apparatus; the phenomenon of line pair turn-over is effectively avoided; and the production efficiency is improved by 30%, and the formation of stress is reduced.

Description

technical field [0001] The invention relates to a cable twisting device, in particular to a twisting device for communication power flexible cables. Background technique [0002] Communication soft cable is a kind of equipment power supply connection line used in communication equipment rooms such as mobile, telecommunications, and Netcom. The product requires properties such as softness and flame retardancy. In order to ensure the roundness of the cable, more fillers need to be added in the cable core, resulting in a larger outer diameter of the finished cable, poor heat dissipation, a large space occupied by the cable laying, and an increase in the manufacturing cost of the cable. In the power cable manufacturing industry, multi-core cables are mainly formed by twisting. In order to ensure the roundness of the wire cores, fillers are added during the cable forming process, resulting in large outer diameters of cables, poor heat dissipation, and high costs. In order to save...
