Abstract
The utility model discloses a steel cord used for an engineering mechanical radial tyre. The steel core comprises a cord body and an externally-winding steel wire wound outside the cord body, wherein the cord body is composed of an inner layer core wire group and six outer layer core wire groups coated and twisted outside the inner layer core wire; and each of the inner layer core wire group and the outer layer core wire groups is formed by twisting three inner layer steel wires and nine outer layer steel wires. The steel cord has the advantages of strong bearing capability, corrosion resistance, penetration resistance, excellent strike-through performance and excellent safety performance.
Description
Technical field
The utility model relates to the steel cord, relates in particular to the steel cord that uses in a kind of all-steel engineering machinery radial.
Background technology
The 7*7+1 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 strand, again strand of internal layer and outer six roots of sensation strand is compiled sth. made by twisting alternately, adds at last the outer silk that twines and forms a cord.Owing to be that mutual the volume twisted with the fingers, be a contact between the steel wire, steel wire easily produces wearing and tearing.The 7*7+1 steel cord can't satisfy by the mode that increases steel cord arranging density in the cord strength demand of large scale engineering tire because cord diameter is larger.Chinese patent CN201120441186.6 discloses a kind of 27 strands of steel cords, it is compiled to twist with the fingers by steel wire and forms, it comprises cover wire layer, wire of intermediate layer layer and steel wire of internal layer layer its feature, the steel wire of internal layer layer is compiled to twist with the fingers by three steel wire floors and is formed, the wire of intermediate layer layer comprises nine steel wires, nine steel wires are done to compile in the same way to twist with the fingers around evenly being arranged in the steel wire of internal layer layer, the cover wire layer comprises 15 steel wires, and 15 steel wires evenly are arranged in to do to compile in the same way around the wire of intermediate layer layer and twist with the fingers Formation cross-section and be circular steel cord.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of bearing capacity is strong, corrosion-resistant, puncture-resistant, strike-through and the good engineering machinery radial steel cord of security performance.
The utility model is achieved by the following technical solution:
Engineering machinery radial steel cord, comprise the cord body and be wrapped in the external outer winding steel wire of cord, six bursts of outer heart yearn groups that described cord body is being twisted with the fingers by internal layer heart yearn group and the outsourcing of internal layer heart yearn group consist of, and described internal layer heart yearn group and outer heart yearn group all are to be compiled to twist with the fingers by three steel wire of internal layer and nine cover wires to form.
The sth. made by twisting of described three steel wire of internal layer and nine cover wires is ordinary lay to identical between described internal layer heart yearn group, outer heart yearn group, cord body and the outer winding steel wire.
The lay pitch of described internal layer heart yearn group and outer heart yearn group is 12.5-18.0mm, and the lay pitch of described cord body is 32.0mm, and the lay pitch of described outer winding steel wire is 5.0mm.
The diameter of described three steel wire of internal layer and nine cover wires is 0.30mm, and the diameter of described outer winding steel wire is 0.20mm.
Be the some contact between the described outer heart yearn group.
The utility model compared with prior art has following beneficial effect:
Six bursts of outer heart yearn groups and a winding steel wire volume that the utility model is being twisted with the fingers by internal layer heart yearn group, the outsourcing of internal layer heart yearn group are twisted type, are comprised of 85 steel wires altogether, and intensity is high, and bearing capacity is large.Be the some contact between the outer heart yearn group, transportable space is large and flexible strong between the steel wire, and fatigue performance is good; Internal layer heart yearn group and outer heart yearn group are ordinary lay, and outer heart yearn group and cord body are ordinary lay, are convenient to strike-through between the outer heart yearn group, and rubber can fully be penetrated in the steel cord, and corrosion-resistant, security performance is good, has prolonged the service life of tire.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
Sequence number among the figure: 1, outer winding steel wire, 2, internal layer heart yearn group, 3, outer heart yearn group, 4, steel wire of internal layer, 5, cover wire.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
According to shown in Figure 1, a kind of engineering machinery radial steel cord of the utility model, comprise the cord body and be wrapped in the external outer winding steel wire 1 of cord, six bursts of outer heart yearn groups 3 that described cord body is being twisted with the fingers by internal layer heart yearn group 2 and 2 outsourcings of internal layer heart yearn group consist of, and described internal layer heart yearn group 2 and outer heart yearn group 3 all are to be compiled to twist with the fingers by three steel wire of internal layer 4 and nine cover wires 5 to form; Be some contact between the described outer heart yearn group 3, the sth. made by twisting of described three steel wire of internal layer 4 and nine cover wires 5 is ordinary lay to identical between described internal layer heart yearn group 2, outer heart yearn group 3, cord body and the outer winding steel wire 1; The lay pitch of described internal layer heart yearn group 2 and outer heart yearn group 3 is 15.0mm, and the lay pitch of described cord body is 32.0mm, and the lay pitch of described outer winding steel wire 1 is 5.0mm; The diameter of described three steel wire of internal layer 4 and nine cover wires 5 is 0.30mm, and the diameter of described outer winding steel wire 1 is 0.20mm.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not consist of the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model above scheme being done that does not break away from technical solutions of the utility model all still belongs within the utility model protection domain.
