Problems solved by technology

In the existing patents, in addition to adopting a fully open structure, the surface modification of the steel wire is used to increase the adhesion between the central steel wire and the rubber to eliminate this disadvantage. The process control needs to be very precise, which will increase the process steps and Cost of production

Embodiment 1

[0029] Figure 4 Shown is a schematic diagram of a transverse cross-sectional structure of a specific application case of the steel wire rope with high structural stability of the present invention. Composed of wound steel wires 7, wherein the diameter of the central steel wire 6 is 0.30 mm, and the diameter of the outer wound steel wire 7 is 0.185 mm; all steel wires are galvanized steel wires, and the deformation height of the central steel wire is measured by a precision profile projector to be 0.345 mm.

[0030] Choose the steel wire rope 18185NT of the same specification under the prior art to compare the adhesion performance with the steel wire rope of the present invention. The rubber material selected for the vulcanization experiment is provided by Shandong Yihe Conveyor Belt Co., Ltd. The test data are shown in Table 1 below.

Abstract

The invention provides a steel wire rope with high structural stability. The steel wire rope comprises a central steel wire and a plurality of winding steel wires distributed around the central steelwire; the diameter of the central steel wire is d, the central steel wire is periodically deformed by a deformation straightener in the weaving and twisting process, the deformation height of the central steel wire is h, and one deformation length is L2, wherein h is equal to 1-1.3d, and L2 is smaller than the twisting distance between the winding steel wires of the steel wire rope and the centralsteel wire during weaving and twisting; the distance between every two adjacent winding steel wires of the winding steel wires evenly distributed around the central steel wire is L1, wherein L1 is smaller than 0.1d. The invention further provides a preparation process of the steel wire rope with the high structural stability. The steel wire rope has the advantages that the glue permeation rate ofthe steel wire rope can be increased to a great degree; the resistance for the central steel wire to pierce a tire is increased, the structure of a framework material is more stable, the safety of the tire is improved, and the service life of the tire is prolonged.

Description

technical field [0001] The invention relates to the technical field of steel wire rope production, in particular to a steel wire rope with high structural stability used as reinforcing materials for rubber and plastic products and a preparation process thereof. Background technique [0002] The fine-gauge steel wire is wound by twisting equipment and then applied to rubber or plastic products, so that rubber and plastic products can obtain excellent performance and long service life. The technical means have been adopted and put into use by many manufacturers. And the products also have a high market share. The most typical examples are radial tires, synchronous belts, and conveyor belts for automobiles. [0003] Taking the use of tires as an example, when the steel cords made of steel monofilaments are used, they will first be arranged into a cord and then vulcanized and bonded with the tire rubber, so that the steel cords can be fixed in the tire. Although the research a...
