Laying up method for twisting low-voltage multi-core cables by laying up drum twister

Abstract

The invention relates to a laying up method for twisting low-voltage multi-core cables by a laying up drum twister, belonging to the technical field of cables. The laying up method for twisting low-voltage multi-core cables by a laying up drum twister comprises the following steps of: (1) during powering on for the first time, drawing by using an insulating cable core or a steel wire rope, and before the head end of the cable core does not reaches a drawing device, reducing the drawing speed or increasing the rotating speed of a twisting cage and keeping the pitch of a cable; (2) peeling off an insulating layer of the cable from a part 5-30cm from the head end of the cable core; (3) lasting the step (1) until the cable core is twisted onto the drawing device; (4) starting a laying up hostto carry out a laying up operation and carrying out subsequent manufacture processes; (5) after the laying up operation is carried out close to a tail end and the cable core is separated from a paying off shaft, peeling off the insulating layer of the cable core at a part 5-30cm from the tail end of the cable core; and (6) pre-twisting the cable core to guarantee that a profiled cable core fan angle or a furrow is aligned to the center. The invention has the advantages of simple process, convenient operation, time and labor saving, simplicity, easy application, high production efficiency, high quality, attractive appearance, and the like.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a cable forming method for twisting low-voltage multi-core cables by a disc cable forming machine. Background technique [0002] At present, the traditional cabling process of low-voltage multi-core cables is as follows: put each core into a reel, pass through the paralleling mold, use insulated cores or steel wire ropes as traction lines, bind the cores, and start the host operating system. This kind of manufacturing process of twisting the low-voltage cable cores, when the cable core is formed, when the head and tail of the cable core pass through the parallel mold, the cable core is easy to twist back, that is, the strands are loose, and it will also cause a serpentine shape on the take-up reel. Phenomenon, manpower is required to apply torque again, and the pitch of the head and tail of the cable core is uneven; this traditional manufacturing process, because the t...

This kind of manufacturing process of twisting the low-voltage cable cores, when the cable core is formed, when the head and tail of the cable core pass through the parallel mold, the cable core is easy to twist back, that is, the strands are loose, and it will also cause a serpentine shape on the take-up reel. Phenomenon, it needs manpower to apply torque again, and the pitch of the head and tail of the cable core is uneven; this traditional manufacturing process, because the stranding direction of the cable core is opposite to the stranding direction of the conductor, and the distance between the pay-off reel and the paralleling mold is relatively small. Far away, it is easy to cause technical problems such as loose strands of conductors
