Description

Drum cable

Technical Field

The utility model relates to a barrel-plating field, in particular to cylinder cable.

Background

Barrel plating, also known as barrel electroplating, is an electroplating process in which a certain number of small parts are placed in a special barrel, and various metal or alloy coatings are deposited on the surfaces of the parts in an indirect conduction manner in a rolling state, so as to achieve the purposes of surface protection and decoration and various functionalities.

The barrel plating is suitable for electroplating small parts which cannot be or are not suitable to be hung due to the influence of factors such as shape, size and the like, and compared with the method of plating the small parts in a hanging mode or a basket mode in the early stage, the barrel plating saves labor force and improves labor production efficiency.

On the cylinder of barrel-plating, the cable plays the effect of leading low-voltage high current, and present traditional cylinder cable receives the cylinder to last work, twists reverse under the effect of buckling, and its life is short, and the life that causes the cylinder is limited greatly, and enterprise's manufacturing cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned problem, provide a cylinder cable, whole tensile strength can be strong with anti buckling performance, heart yearn conductor individual layer or multilayer transposition simultaneously, and the transmission is stable, has improved the life of wire rod and the stability of electroplating greatly.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a roller cable comprises a core wire layer, an insulating layer, a tensile layer and a sheath from inside to outside, wherein the tensile layer is a Kevlar fiber layer which is independently arranged or Kevlar fiber yarns which are compounded with the insulating layer and/or the sheath, and the Kevlar fiber yarns are bundled in the core wire layer.

Further, the insulating layer is a PVC layer.

Further, the core wire layer is a conductor single-layer stranded core wire or a conductor multi-layer stranded core wire.

Further, the sheath is a wear layer sheath.

Further, the core wire layer 1 has a stranding pitch ratio of 15, and the outermost layer is stranded to the right.

To sum up, the utility model discloses possess following advantage:

the utility model provides a cylinder cable, whole tensile strength can be strong with anti buckling performance, and heart yearn conductor individual layer or multilayer transposition simultaneously transmit stably, have improved the life of wire rod and the stability of electroplating greatly.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

a drum cable, as shown in fig. 1, comprises a core wire layer 1, an insulating layer 2, a tensile layer 3 and a sheath 4 from inside to outside.

The core wire layer is a conductor single-layer stranded core wire or a conductor multi-layer stranded core wire, and has a better transmission effect.

Kevlar fiber yarns are bound in the core wire layer, specifically, when the core wires are twisted, the pitch ratio is 15, objects with tensile effect, such as hemp ropes, are filled, specifically, the twisting direction is rightward, and a tensile wrapping belt is adopted.

On the cross-section setting, core wire cross-section 35mm when corresponding cable diameter 8 mm.

When heart yearn cross-section 50mm, corresponding cable diameter 9.5 mm.

When core wire cross-section 70mm, corresponding cable diameter 11.5 mm.

When core wire cross-section 95mm had been formed, the corresponding cable diameter 13.5 mm.

When the core wire cross section is 120mm, the corresponding cable diameter is 15.5 mm.

And the insulating layer 2 is a PVC layer.

The sheath is the wearing layer sheath, has guaranteed the wire rod and has continued frictional wear resistance in the electroplating process, has improved life.

Furthermore, the tensile layer is the Kevlar fiber layer that sets up alone, and Kevlar fiber possesses better tensile and resistant bending property, the life of this cylinder cable in lasting electroplating process of assurance that can be better.

Meanwhile, the Kevlar fiber layer forms an independent coating layer and is matched with the wear-resistant layer, so that the service life of the cable is greatly prolonged, and the effect of the cable is superior to that of the existing roller cable.

Example 2:

the drum cable of the embodiment comprises a core wire layer 1, an insulating layer 2, a tensile layer 3 and a sheath 4 from inside to outside.

On the section setting, when the core wire section is 35mm, the diameter of the corresponding cable is 8 mm;

when heart yearn cross-section 50mm, corresponding cable diameter 9.5 mm.

When core wire cross-section 70mm, corresponding cable diameter 11.5 mm.

And the insulating layer 2 is a PVC layer.

Furthermore, the tensile layer is formed by compounding Kevlar fiber yarns in the insulating layer 2, or in the wear-resistant sheath, or both.

This combined type's structural design promotes the whole tensile and resistant performance of buckling of cable through the Kevlar cellosilk, improves the cable and continuously buckles torsional life in the cylinder.

To sum up, the whole tensile property of this scheme and anti buckling performance are strong, and heart yearn conductor individual layer or multilayer transposition simultaneously, the transmission is stable, has improved the life of wire rod and the stability of electroplating greatly.
