Abstract
The invention discloses a process for manufacturing a spliced conductor type cable. The process includes the steps that metal blanks are utilized to draw conductors, the conductors comprise the inner conductors and the outer conductors, wherein the cross sections of the inner conductors are circular, the inner conductors are formed by a plurality of core wires of which the cross sections are semicircular or of a sector shape, the cross sections of the outer conductors are of a circular ring shape, the outer conductors and the inner conductors are spliced to form circular cross sections, and the outer conductors are formed by splicing a plurality of core wires of which the cross sections are of a tile shape; the core wires of the inner conductors and the core wires of the outer conductors are spliced into wires of which the cross sections are circular, and then the wires are twisted around a center shaft by a wire twisting machine, wherein the cross sections of the core wires are semicircular or of the sector shape or of the tile shape; inner insulating layers wrap the wires in an extrusion molding mode, the plurality of sets of wires wrapped by the inner insulating layers are circular, and outer sheathes wrap the plurality of sets of twisted wires. According to the process, the core wires are machined into the semicircular shape or the sector shape or the tile shape which can be spliced to the circular shape, then, the core wires are twisted to produce the wires, and therefore gaps among the core wires are reduced, the compaction degree of the wires is increased, and the geometric dimensions of the wires are reduced.
Description
Technical field
The present invention relates to the cable technology field, relate in particular to a kind of splicing conductor type cable manufacture craft.
Background technology
Cable completes by drawing, twist system and coating three kinds of techniques.Cable normally forms by multiple conducting wires is stranded, and every wire is provided with inner insulating layer outward, and is twisted into round the Yi Gen center, and whole outside is surrounded by the cover layer of high-insulation.And every wire is by many stranded the forming of heart yearn.In prior art, every core section is circular, when many heart yearns are stranded, between heart yearn and heart yearn, can produce gap, causes the compression degree inadequate, makes the wire physical dimension larger, takies larger use area, urgently improves.
Summary of the invention
The problem existed for prior art, the object of the invention is to propose a kind of splicing conductor type cable manufacture craft, to improve the compression degree of wire, reduces the wire physical dimension.
A kind of splicing conductor type cable manufacture craft comprises the following steps:
Draw conductor with metal stock, described conductor comprises inner wire and outer conductor, described inner wire cross section is circular, by a plurality of cross sections, be that semicircle or fan-shaped heart yearn form, described outer conductor cross section is annular, and with form circular cross-section after the splicing of described inner wire, by the heart yearn of a plurality of watts of tee sections, be spliced;
To there is the inner wire heart yearn of above-mentioned cross sectional shape and outer conductor heart yearn and be spliced into cross section and be circular wire, stranded round central shaft by stranding machine;
Coat inner insulating layer by the extrusion molding mode in described wire outside;
The wire stranding that described many groups are coated to inner insulating layer is circular;
At stranded described many group wire outer cladding oversheaths.
Preferably, also comprise: wire armoring in stranded multiple conducting wires outer cladding.
Preferably, describedly with metal stock, draw conductor, specifically comprise: the traction metal stock, by mould, makes described metal stock cross-sectional area compressed, forms and meets the wire that the cross-sectional area shape and size require.
Preferably, described mould is pinch roller.
In the present invention, heart yearn is processed into and can splices conglobate semicircle, fan-shaped or watt shape, then twist together and make wire, reduced can produce gap between heart yearn and heart yearn, improve the compression degree of wire, reduce the wire physical dimension.
The accompanying drawing explanation
Fig. 1 is a kind of splicing conductor type cable fabrication processing figure in the embodiment of the present invention.
Embodiment
Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment:
The embodiment of the present invention provides a kind of splicing conductor type cable manufacture craft, as shown in Figure 1, comprises the following steps:
The embodiment of the present invention provides the above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
Claims (4)
