Abstract
The utility model discloses twenty-seven bundles of steel cords, which comprise inner layers of core cords, intermediate layers of core cords and outer layers of core cords, wherein the inner layers of core cords are formed by weaving and entwisting three inner layers of steel cords (1); the intermediate layers of core cords comprise nine intermediate layers of steel cords (2) which are uniformly configured around the inner layers of core cords for weaving and entwisting at the same direction; the outer layers of core cords comprise fifteen outer layers of steel cords (3) which are uniformly configured around the intermediate layers of core cords for weaving and entwisting at the same direction so as to form the steel cords with circular cross sections. The twenty-seven bundles of steel cords provided by the utility model not only have small diameters, and can increase the integral intensity of a tyre through improving the arrangement density of the steel cords in cord fabrics; and outer wound cords are not provided, also the abrasion to the outer layers of the steel cords by the outer wound cords can be prevented, the service life of the tyre is prolonged, the manufacturing procedures are reduced, and the cost is lowered.
Description
Technical field
The utility model relates to a kind of 27 strands of steel cords.
Background technology
The 7*7+1 shaped steel cord that uses in the all-steel engineering machinery radial is at present compiled in advance by seven steel wires and to be twisted with the fingers into strand, again strand of internal layer and outer six roots of sensation strand is compiled sth. made by twisting alternately, adds the outer silk that twines at last and forms a cord.Owing to be that mutual the volume twisted with the fingers, be a contact between the steel wire, steel wire is prone to produce wearing and tearing.7*7+1 shaped steel cord can't satisfy the strength demand of big specification engineering tyre through the mode that increases steel cord arranging density in the cord because cord diameter is bigger.
Summary of the invention
The utility model provides a kind of 27 strands of steel cords, and not only diameter is little for it, can increase the bulk strength of tire through steel cord arranging density in the raising cord.Nothing is outer not to twine silk, and can avoid outer wearing and tearing that twine silk to cover wire, the service life of improving tire, and the minimizing procedure of processing reduces cost.
The utility model has adopted following technical scheme: a kind of 27 strands of steel cords; It comprises internal layer heart yearn, intermediate layer heart yearn and outer heart yearn; The internal layer heart yearn is compiled to twist with the fingers by three steel wire of internal layer and is formed, and the intermediate layer heart yearn comprises nine wire of intermediate layer, and nine wire of intermediate layer are done to compile in the same way to twist with the fingers around evenly being arranged in the internal layer heart yearn; The skin heart yearn comprises 15 cover wires, and work was compiled the steel cord of sth. made by twisting formation cross section for circle in the same way around 15 cover wires evenly were arranged in the intermediate layer heart yearn.
The sth. made by twisting of described internal layer heart yearn, intermediate layer heart yearn and outer heart yearn is Z and twists with the fingers to identical, and it is 6.3mm that the internal layer heart yearn is compiled the lay pitch of twisting with the fingers, and it is 12.5mm that the intermediate layer heart yearn is compiled the lay pitch of twisting with the fingers, and it is 18.0mm that outer heart yearn is compiled the lay pitch of twisting with the fingers.The diameter of described steel wire of internal layer, wire of intermediate layer and cover wire is 0.245mm.
The utlity model has following beneficial effect: the utility model improves intensity of steel wire, reduces the steel wire radical, increases steel wire diameter; Satisfy under the prerequisite of steel cord strength requirement in assurance; Reduce steel cord line density, reduce the steel cord diameter, and satisfy the strength demand of big specification engineering tyre through the mode that increases steel cord arranging density in the cord; Reduce the tire deadweight, reduce raw materials consumption.Compile in the same way between layer of the utility model and the layer and twist with the fingers, do not add the outer silk that twines, reduce the wearing and tearing between the steel wire; Improve the abrasion resistance properties and the anti-fatigue performance of steel cord; Satisfy engineering machinery radial requirements of one's work under the road conditions rugged environment for a long time, improve the service life of tire, also reduced procedure of processing; Reduce production costs, increase economic efficiency.
Description of drawings
Fig. 1 is a sketch map for the structure of the utility model.
The specific embodiment
In Fig. 1, the utility model provides a kind of 27 strands of steel cords, and it comprises internal layer heart yearn, intermediate layer heart yearn and outer heart yearn; The internal layer heart yearn is twisted with the fingers by three steel wire of internal layer, 1 volume and is formed, and the intermediate layer heart yearn comprises that 2, nine wire of intermediate layer 2 of nine wire of intermediate layer evenly are arranged in the internal layer heart yearn and make to compile in the same way sth. made by twisting on every side; Outer heart yearn comprises 15 cover wires 3; Work was compiled the steel cord of sth. made by twisting formation cross section for circle in the same way around 15 cover wires 3 evenly were arranged in the intermediate layer heart yearn, and the diameter of steel wire of internal layer 1, wire of intermediate layer 2 and cover wire 3 is 0.245mm, and the sth. made by twisting of internal layer heart yearn, intermediate layer heart yearn and outer heart yearn is to identical; Being Z twists with the fingers; It is 6.3mm that the internal layer heart yearn is compiled the lay pitch of twisting with the fingers, and it is 12.5mm that the intermediate layer heart yearn is compiled the lay pitch of twisting with the fingers, and it is 18.0mm that outer heart yearn is compiled the lay pitch of twisting with the fingers.
Claims (3)
