Abstract
The utility model discloses a super high -strength steel cord, including heart yearn steel wire and outer layer wire, its characterized in that, the heart yearn steel wire be three, be trefoil formation, and outer layer wire be eight, the equipartition is in the periphery of heart yearn steel wire, just heart yearn steel wire and outer layer wire syntropy compile and twist with the fingers, form the cross -section and be circular shape steel cord. The utility model discloses have that intensity height, strike -through performance are good, corrosion resisting property reinforce, low dead weight, fatigue performance can high advantages, and its rugosity only be 3+9+1 type steel cord's 80 percent, makes covering gluey thickness and can reducing of cord, the quantity of reduction sizing material has improved economic benefits.
Description
Technical field
The utility model relates to a kind of steel cord, especially relates to the steel cord that in a kind of pneumatic tire, band bundled layer uses, belongs to steel wire rod technical field.
Background technology
Current domestic tubeless passenger vehicle tyre many uses 3+9+1 shaped steel wire cord is as carcass, it is by internal layer three heart yearn steel wires and outer nine steel wires, add one and twine silk composition outward, twining silk and cover wire outward twists with the fingers to alternately, in point cantact between steel wire, nine steel wire dense arrangement are around heart yearn steel wire, almost very close to each other between cover wire, make rubber be difficult to penetrate in heart yearn steel wire.Because the attached glue of heart yearn steel wire is insufficient, tire is once impaired, and moisture or salinity will penetrate in all-steel cord, accelerates the corrosion of all-steel cord, reduces the service life of tire.Repeatedly bent due to when tire high speed, long distance travel simultaneously, easily cause the outer silk that twines to loosen, rupture, affect fatigue performance and the security performance of tire.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of superhigh intensity, strike-through performance are good, strong, the low deadweight of corrosion resistance ability, high fatigue property super-high strength steel cord.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of super-high strength steel cord, comprise heart yearn steel wire and cover wire, it is characterized in that, described heart yearn steel wire is three, be triangularly arranged, and described cover wire is eight, is distributed on the periphery of heart yearn steel wire, and described heart yearn steel wire and cover wire compile sth. made by twisting in the same way, Formation cross-section is circular all-steel cord.
Further, described heart yearn steel wire and cover wire compile the direction of twisting with the fingers be S twist with the fingers to.And heart yearn steel wire is identical with the diameter of cover wire, is 0.22mm.
And the lay pitch that sth. made by twisting compiled by described heart yearn steel wire is 6.3mm.It is 12.5mm that cover wire compiles the lay pitch of twisting with the fingers.
Usefulness of the present utility model is: cover wire of the present utility model adopts eight steel wires, because using super-high strength steel silk, the mechanical property of steel cord can be improved, make tire and can meet or exceed corresponding bearing capacity, the heart yearn of eight monofilament to centre not exclusively wraps up, make between steel wire, to leave more gap, be convenient to the infiltration of rubber, be conducive to improving the bonding force between rubber and steel cord, thus avoid because moisture (moisture) enters into steel cord inside and cause corrosion, the infiltration of sizing material simultaneously can limit the relative movement between steel wire effectively, reduce to wear and tear between steel wire, and the utility model is produced by one-step shaping method, significantly can reduce the production cost of all-steel cord, and its rugosity is only 80% of 3+9+1 shaped steel wire cord, the glue thickness that covers of cord is minimized, reduce the consumption of sizing material, improve economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the lay pitch structural representation of steel cord of the present invention.
The implication of Main Reference Numerals in figure:
1, heart yearn steel wire 2, cover wire.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
Fig. 1 is the structural representation of the utility model one embodiment, and Fig. 2 is the lay pitch structural representation of steel cord of the present invention.
Shown in Fig. 1 and Fig. 2: super-high strength steel cord, comprise heart yearn steel wire 1 and cover wire 2, heart yearn steel wire 1 is three, be triangularly arranged, and cover wire 2 is eight, be distributed on the periphery of heart yearn steel wire 1, and heart yearn steel wire 1 and cover wire 2 compile sth. made by twisting in the same way, be S twist with the fingers to, Formation cross-section be circular all-steel cord.
And in the present embodiment, heart yearn steel wire 1 is identical with the diameter of cover wire 2, is 0.22mm, the lay pitch of twisting with the fingers compiled by heart yearn steel wire is 6.3mm, and it is then 12.5mm that cover wire compiles the lay pitch of twisting with the fingers, and steel wire is linear contact lay.
Cover wire 2 of the present utility model adopts eight steel wires, because using super-high strength steel silk, the mechanical property of steel cord can be improved, make tire and can meet or exceed corresponding bearing capacity, the heart yearn of eight monofilament to centre not exclusively wraps up, make between steel wire, to leave more gap, be convenient to the infiltration of rubber, be conducive to improving the bonding force between rubber and steel cord, thus avoid because moisture (moisture) enters into steel cord inside and cause corrosion, the infiltration of sizing material simultaneously can limit the relative movement between steel wire effectively, reduce to wear and tear between steel wire, and the utility model is produced by one-step shaping method, significantly can reduce the production cost of all-steel cord, and its rugosity is only 80% of 3+9+1 shaped steel wire cord, the glue thickness that covers of cord is minimized, reduce the consumption of sizing material, improve economic benefit.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
