Abstract
The utility model discloses a high-elongation steel cord which is twisted by steel wire strands; the steel wire strands are twisted by steel wires; the utility model is twisted by four steel wire strands with orthohexagonal sections; the steel wire strand is twisted by seven steel wires; the steel strand and the steel cord have the same direction of twist. The length of twist of steel cord is smaller; line-contacts are between steel wires and between steel strands; the single wire of the steel wire strand tightly winds and can not produce structure damage and has a big effective sectional area, thereby being big in interceptive load; the breaking force is more than or equal to 6610 N and the breaking elongation is between 6.5 percent and 7.5 percent; the utility model uses a belted layer of the meridian tyre as the protective layer of the tyre and can improve anti-impact load capacity and prevent the tyre body of the tyre from being damaged.
Description
Technical field
The utility model relates to a kind of high elongation steel cord, and height used in the outermost casing ply of especially a kind of Reinforced Rubber tire extends the steel cord.
Background technology
In the prior art, the high elongation of 3 * 7*0.22,7 * 7*0.22 steel cord and still has been widely used in and has strengthened tyre protecting belt or band bundled layer, but the high elongation of 3 * 7*0.22 all-steel cord elongation at break is lower, about about 4.5%; The high elongation of 7 * 7*0.22 all-steel cord is formed by seven bursts of steel strand twistings, and to having relatively high expectations of strander, common strander can't be finished, the manufacturing cost costliness.
Summary of the invention
The utility model provides a kind of low cost of manufacture, percentage elongation height, decay resistance and security good, and height used in the outermost casing ply of Reinforced Rubber tire extends the steel cord.
The utility model has adopted following technical scheme: a kind of high elongation steel cord, compiling sth. made by twisting by steel strand forms, steel strand is compiled to twist with the fingers by steel wire and is formed, it is that orthohexagonal steel strand volume sth. made by twisting forms by four cross sections, described steel strand is compiled to twist with the fingers by seven steel wires and is formed, and the sth. made by twisting of steel strand and steel cord is to identical.
In the utility model, the lay pitch of steel cord is 14.0～16.0mm, and the lay pitch of steel strand is 5.0～8.5mm; Described gauge of wire is all identical, and diameter is 0.25
-0.35mm; The Fracture Force of described steel cord is more than or equal to 6610N; The Breaking elongation of described steel cord is 6.5～7.5%; Be the line contact between the described steel wire, between the steel strand.
After adopting as above technical scheme, the lay pitch of steel cord is less, be the line contact between the steel wire, between the steel strand, the monofilament in the steel strand closely twines, and does not produce structural deterioration, effective cross sectional area is big, so it is big to block loading, Fracture Force is more than or equal to 6610N, and Breaking elongation is between 6.5～7.5%, easy strike-through between the steel strand, corrosion resistance is strong.It is formed by four steel strand twistings, can finish low cost of manufacture on common strander.The band bundled layer that the steel cord of this structure is used for radial; protective layer as tire; can improve the capacity of resisting impact load of tire; the carcass that prevents tire is impaired; can prevent again that simultaneously band bundled layer steel cord from causing steel cord corrosion and damage because of puncture and incised wound cause moisture and moisture content to infiltrate; improve the security performance that tire uses, prolonged service life.
Description of drawings
Fig. 1 is the schematic cross-section of a kind of high elongation steel cord of the utility model
The specific embodiment
According to shown in Figure 1, a kind of high elongation steel cord of the utility model, it is formed by 28 steel wire twistings, and used steel wire diameter is all identical, is 0.2 5～0.35mm.At first seven steel wires being compiled and being twisted with the fingers into the cross section is orthohexagonal steel strand, twists with the fingers to being S, and the lay pitch is 5.0～8.5mm; Again four steel strands are compiled sth. made by twisting in the same way, twist with the fingers to being S, the lay pitch is 14.0～16.0mm.Be the line contact between steel wire, the steel strand.The Breaking elongation of the steel cord of Sheng Chaning is 6.5～7.5% thus, and Fracture Force is more than or equal to 6610N.
Claims (6)
1. one kind high elongation steel cord, formed by steel strand volume sth. made by twisting, steel strand is compiled to twist with the fingers by steel wire and is formed, and it is characterized in that it is that orthohexagonal steel strand volume sth. made by twisting forms by four cross sections, described steel strand is compiled to twist with the fingers by seven steel wires and is formed, and the sth. made by twisting of steel strand and steel cord is to identical.
2. a kind of high elongation steel cord according to claim 1, the lay pitch that it is characterized in that the steel cord is 14.0～16.0mm, the lay pitch of steel strand is 5.0～8.5mm.
