Technical Field

The invention relates to a push-pull cable steel wire rope capable of being lubricated by itself.

Background

The common galvanized steel wire rope for the automobile door locking inhaul cable has the structure of 1.2(1+12) or 1.2(1+ 14). Most of the central wires of the product are oil quenching wires, the galvanized wires on the outer layer are arranged closely, no gap exists basically, and little grease is remained on the surface of the steel wire rope. The advantages are that the oil quenching wire has good straightness and better elasticity, the steel wire rope twisted by the oil quenching wire has good straightness and is not easy to bend, but the defects are that the central wire is non-galvanized wire, no coating protects the surface of the steel wire, and the oxidation resistance of the steel wire is not good. Meanwhile, the outer layer wires of the inhaul cable are arranged closely, basically, no gap exists, oil content is low, the steel wire rope can be oxidized, and the steel wire rope can be corroded to be generated when the steel wire rope is serious, particularly, the steel wire rope is exposed to the outside. The operation when being unfavorable for locking the door is accompanied by big noise simultaneously, has reduced the life of car door cable.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide a push-pull cable steel wire rope capable of being lubricated by itself, which can carry lubricating grease, so that the steel wire rope has good lubricity and corrosion resistance.

In order to achieve the purpose, the invention is realized by the following technical scheme:

a self-lubricating push-pull cable steel wire rope comprises a central wire and an outer layer wire, wherein the outer layer wire is spirally wound outside the central wire in the same twisting direction, the outer layer wire is composed of a plurality of steel wires, a gap is reserved between the head and the tail of the steel wires, and the rest steel wires are tightly attached together.

The width of the gap is 0.5-1.5 times of the diameter of one steel wire.

The central wire and the steel wire are both galvanized steel wires.

The outer layer yarn lay length is 4.0-18 mm.

The push-pull cable steel wire rope is treated by greasing.

The steel wire rope of the push-pull cable is twisted by adopting a conical pre-deformer to pre-deform the steel wire, the wheel diameter of the pre-deformer is 1.2-3.0 times of the rope diameter of the steel wire rope, and the wheel end distance of the pre-deformer is 0.8-1.2 times of the twisting distance.

Compared with the prior art, the invention has the beneficial effects that:

the self-lubricating push-pull cable steel wire rope is suitable for the stay cable for the automobile door. The central wire and the outer wire are made of galvanized steel wires with coatings, so that the steel wires are protected, the central wire is not easy to oxidize or rust, and the oxidation resistance of the whole push-pull cable steel wire rope is improved. In addition, a gap is reserved in the outer layer wire, lubricating grease is easy to carry at the gap, and can be retained on the push-pull cable steel wire rope, so that the push-pull cable steel wire rope has good lubricity and corrosion resistance, the friction between the surface of the push-pull cable steel wire rope and the inner wall of the inhaul cable assembly is further reduced, the noise during operation is reduced, and the service life of the push-pull cable steel wire rope is prolonged; meanwhile, the repeated pushing and pulling times of the push-pull cable steel wire rope are improved, and the service life of the automobile door stay cable is prolonged.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

Examples

Referring to fig. 1 and 2, the self-lubricating push-pull cable steel wire rope comprises a central wire 2 and an outer layer wire 1, wherein the central wire 2 is a hard galvanized steel wire, the ring diameter is larger than 450mm, and the rise is smaller than 40 mm. The same spiral winding of outer silk 1 twist to 3 is outside at central silk 2, twist to 3 for levogyration or dextrorotation, and outer silk 1 comprises 13 the same zinc-plated steel wires of diameter, leaves the gap between the head and the tail steel wire, guarantees to have the gap that is equivalent to 1 outer silk 1 diameter in two lay lengths 4, black part in figure 1, 2, and will be even, and the inseparable subsides between the other steel wires are in the same place, and outer silk 1 pastes with central silk 2 and is in the same place.

The width of the gap is 0.5-1.5 times of the diameter of one steel wire, and the gap is used for carrying lubricating grease. The central wire 2 is a galvanized hard steel wire, and the outer layer wire 1 is a galvanized steel wire. The galvanized layer has a protection effect on the steel wire, the galvanized hard steel wire has good straightness and elasticity, and the push-pull cable steel wire rope twisted by the galvanized hard steel wire has good straightness and is not easy to bend.

The lay length 4 of the outer layer wire 1 is 4.0-18 mm, and the surface of the steel rope has uniform and oil-containing gaps in a twisted finished product in the range. Before the push-pull cable steel wire rope is installed in the cable assembly, the surface of the push-pull cable steel wire rope needs to be subjected to primary greasing treatment, and grease at the moment can remain in gaps on the surface of the steel wire rope.

The steel wire rope twisting of the push-pull cable adopts a conical pre-deformer to pre-deform the steel wire, the wheel diameter of the pre-deformer is 1.2-3.0 times of the rope diameter of the steel wire rope, and the wheel end distance of the pre-deformer is 0.8-1.2 times of the twisting distance 4. The effect that the steel wire can not be scattered after being cut off is achieved, and the subsequent processing is facilitated.
