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

Abstract

The invention relates to the technical field of cable processing, in particular to a cable stranding process and a stranding device. The stranding device includes a driving assembly and a stranding assembly. According to the moving direction of the cable, the driving assembly is located at the The moving head end of the cable; the drive assembly includes a support plate, a main drive motor, and a main shaft. It includes a front winch, a back-twist unit, a rear winch and a winch. The middle part of the front winch has a through first connecting hole, and the middle part of the rear winch has a through second connecting hole. The main shaft, the front winch and the rear winch are synchronously driven. The connecting and untwisting unit is arranged between the front winch and the rear winch. The invention is used to solve the problems in the prior art that it is not suitable for the manufacture of cable bundles with many winding wires and that if the tension of a single wire changes during the twisting process, the quality of the twisted cables will be affected.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a twisting device. 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 material becomes smaller, so that the resist...
