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 host to 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
The invention belongs to the cable technology field, particularly relate to a kind of disc type cabler and be used for the stranded stranding method of low pressure multicore cable.
Background technology
At present, the cabling process of traditional low pressure multicore cable is: with each core sabot, pass the doubling mould, as draught line, after the core binding, start host operating system with insulated wire cores or steel wire rope.This manufacturing process that the low-voltage cable core is stranded is during stranding, when the head and the tail head of cable core is crossed the doubling mould, the easy back twist of cable core, just loose strand, also can cause has snakelike phenomenon on take-up reel, need manpower to apply torsion once more, and the head and the tail cephalomere of cable core is apart from inhomogeneous; This traditional manufacturing process, because the cable core direction of lay is opposite with the direction of lay of conductor, and draw drum and doubling mould cause technical problems such as conductor broken lot easily apart from far away.
Summary of the invention
The present invention provides a kind of disc type cabler to be used for the stranded stranding method of low pressure multicore cable for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide that a kind of to have technology simple, easy to operate, economical and practical, time saving and energy saving, simple and easy to do, the machining accuracy height, the production efficiency height, the disc type cabler of characteristics such as quality and outward appearance are good is used for the stranded stranding method of low pressure multicore cable.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of disc type cabler is used for the stranded stranding method of low pressure multicore cable, with each core sabot, passes the doubling mould, and stranded stranding is characterized in that: the stranded stranding of multicore cable comprises following processing step:
Step 5, stranding are near the tail head, and core at the about 5-30cm of distance cable core tail head place, is peeled the cable core insulating barrier off after breaking away from paying out reel;
Step 6, cable core is carried out pretwist, guarantee to have the cable core fan angle or watt groove centring of die mould.
The present invention can also adopt following technical scheme:
Described disc type cabler is used for the stranded stranding method of low pressure multicore cable, is characterized in: at first 10-25cm place of distance cable core, peel the insulating barrier 5-20cm of cable core off.
Described disc type cabler is used for the stranded stranding method of low pressure multicore cable, is characterized in: at distance cable core tail head 10-25cm place, peel the insulating barrier 5-20cm of cable core off.
Advantage and good effect that the present invention has are:
The disc type cabler is used for the stranded stranding method of low pressure multicore cable, owing to adopted brand-new technology scheme of the present invention, compared with prior art, processing technology adopts the method that reduces hauling speed or increase strand cage rotating speed, prevent first back twist of cable core, adopt the method for peeling SI semi-insulation off to prevent first conductor broken lot of cable core then, improved operating efficiency; Avoid the snakelike phenomenon of take-up reel appearance on the cable core simultaneously, guaranteed the presentation quality of product.It is simple, easy to operate, economical and practical, time saving and energy saving that the present invention has technology, simple and easy to do, machining accuracy height, production efficiency height, advantage such as quality and outward appearance are good.

Head is peeled the cable core structure schematic diagram of insulating barrier off headed by Fig. 2;
Fig. 3 peels the cable core structure schematic diagram of insulating barrier off for the tail head.
Among the figure, the 1-conductor; The 2-insulating barrier, the 3-conductor; The 4-insulating barrier.
Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, be described in detail as follows:
A kind of disc type cabler is used for the stranded stranding method of low pressure multicore cable, comprises following machining process:
Step 5, stranding, at the about 20 centimeters places of distance cable core tail head, are peeled the insulating barrier 4 of cable core about 10 centimeters off after core breaks away from paying out reel near the tail head, prevent cable core tail head conductor 3 broken lots;
Step 6, then, device operator reply cable core carries out suitable pretwist, guarantees to have the cable core fan angle or watt groove centring of die mould, in order to avoid the tail head has snakelike phenomenon because cable core has pitch not cause the pine thigh on take-up reel.
Present embodiment disc type cabler is used for the stranded stranding skill of low pressure multicore cable, respectively peels partial insulative layer off at cable core head and the tail head, and is simple and convenient, and this skill provides assurance for the quality of cable and outward appearance etc., and time saving and energy saving, simple.
