Abstract

The invention relates to the technical field of cable processing, in particular to a cable twisting process and a twisting device thereof. The twisting device comprises a driving assembly and a wire twisting assembly, and according to the movement direction of a cable, the driving assembly is located at the movement head end of the cable; the driving assembly comprises a supporting plate, a main driving motor and a main shaft, the main driving motor is fixedly installed at the front end of the supporting plate and connected with the front end of the main shaft, and the tail end of the main shaft is connected with the wire twisting assembly; the wire twisting assembly comprises a front winch, an untwisting unit, a rear winch and a twisting device, a first through connecting hole is formed in the middle of the front winch, a second through connecting hole is formed in the middle of the rear winch, the main shaft, the front winch and the rear winch are in synchronous transmission connection, and an untwisting unit is arranged between the front winch and the rear winch. The process and the device are used for solving the problems that in the prior art, a device is not suitable for themanufacturing of cable bundles with many winding wires, and the quality of stranded cables can be affected if the tension of a single wire is changed in the stranding process.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable twisting process and a twisting device thereof. Background technique [0002] With the advancement of wire and cable processing technology, the conductors of power cables have begun to develop into a shaped wire stranded structure. The shaped wire stranded conductor has the characteristics of a small outer diameter layer and a smooth surface. And the application of shaped wire stranded conductors in power cables also has the advantages of reducing cable breakdown rate, smaller conductor outer diameter under the same cross-section, reducing the use of insulating materials and sheath materials, and improving conductor compression coefficient (0.98). [0003] Comparing the copper stranded conductor with shaped wire to the round compact conductor, under the same resistance, the plastic variation of copper is small, and the molecular structure distribution in the copper materia...

AI Technical Summary

Problems solved by technology

[0008] (1) The synchronous motor of the wire harness machine only drives one end of the stranding drum to rotate, and cannot drive the stranding drum to rotate synchronously everywhere. If the stranding drum grows due to the need to wind multiple wires, it is easy to cause stress to concentrate on the strands. The connection between the wire drum and the drum shaft makes the wire drum deform after long-term use, which affects the service life of the wire harness, so this solution is not suitable for the manufacture of cable bundles with more winding wires;

[0009] (2) When twisting a single wire, if the tension of the single wire changes, it will affect the quality of the twisted cable and reduce the production quality of the wire binding machine
