Description

Technical Field

[0001] The utility model relates to the technical field of cable twisting machines, in particular to a cable twisting device for producing fire-resistant insulated wires and cables. Background Art

[0002] Wire twisting machine is a kind of mechanical equipment that can be widely used in twisting various soft / hard conductor wires, so that multiple single conductors are twisted into one strand to meet the process requirements of wire materials, such as twisting various soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper clad steel, copper clad aluminum, etc.) and electronic wires. Wire twisting machines can be generally divided into single twisting machines, pair twisting machines, high-speed twisting machines, back-twisting machines, cage twisting machines, frame twisting machines, tubular twisting machines and disc twisting machines according to the twisting method. Among them, cage twisting machines are large-scale twisting equipment, which are widely used in the twisting of various composite cables (such as fire-resistant insulated wires, high-voltage wires, etc.).

[0003] When existing cage-type twisting machines twist cables, they generally use their cable bundle reels to release the cable bundles of multiple strands, and then tighten the bundles along the terminal twisting reels, and use their rotating state to twist the multiple strands of cables. However, most existing cable bundle reels are of a single fixed form, and the cable bundle tightening ability is relatively single, resulting in a large friction resistance between the cable and the cable bundle reel when the cable is released, which is not conducive to cable twisting and is very likely to cause cable wear. To this end, those skilled in the art provide a cable twisting device for the production of fire-resistant insulated wires and cables to solve the problems raised in the above background technology.
