Abstract
The utility model discloses a steel cord forautomobile tires. The steel cord comprises an inner layer and an outer layer, wherein the inner layer consists of four steel wires, and the outer layer consists of six steel wires; the six steel wires of the outer layer are unevenly distributed around the four steel wires of the inner layer and twisted around the four steel wires of the inner layer to form the steel cord, and the cross section of the steel cord is in an irregular polygon shape; the four steel wires of the inner layer are not twisted, and the six steel wires of the outer layer are twisted around the four steel wires of the inner layer in an S direction. The high-strength steel cord has the advantages of high tensile strength, good rubber penetration performance, high adhesive force, high corrosion resistance, shock resistance and the like when being applied to all-steel load-bearing radial tires; and the production cost can also be reduced due to one-step molding.
Description
Technical field
The utility model relates to steel cord, particularly a kind of automobile tire steel cord.
Background technology
In the modern life and production, people are increasing to the demand of automobile, bogie industry, this has just driven developing rapidly of tire industry, also tire enterprise has been proposed to more and more higher requirement, and endurance quality, speed ability, security performance and the refresh rate of tire improve constantly.Under competitive pressure, cost efficiency is also the requisite measure of tire enterprise seeking development in market, and the saving of limited resources is used also manufactured industry to bring into schedule.Therefore, constantly accepting the challenge of performance, cost and energy conservation as the all-steel cord of tyre framework material.Band bundled layer is the critical component of all-steel load-bearing radial tire, has born approximately more than 60% load of tire, and its framework material performance is one of key factor determining tire combination property.Band bundled layer is focused on rubber osmosis performance, rigidity, bond properties, tensile strength, decay resistance, anti-compression properties, shock resistance and DIMENSIONAL STABILITY etc. with all-steel cord.
Traditional high-capacity tyre band bundled layer mostly is regular sandwich construction (such as 3+9+15 Series Steel cord) with steel cord, manufacture route complexity, need multistep moulding, production efficiency is low, and due to tactical rule, steel wire of internal layer is wrapped up completely by skin, has limited the contact area of steel wire and rubber, has reduced bonding force and the strike-through performance of cord.Irregular double-decker design helps all-steel cord to realize better rubber osmosis performance from twisting structure, by ectonexine being selected to suitable radical, be twisted into the space that rope can not form sealing, also can leave space at skin allows rubber infiltrate, by to monofilament, prefabricated distortion has not only increased gap and the specific area between steel wire, sizing material can be infiltrated into completely, and the performance such as the rigidity of the adjustable cord of control to deflection, but this structure is also had higher requirement to cord technique.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile tire steel cord, and it is simple in structure, production efficiency is high, has the advantages such as strike-through performance is good, bonding force is high, decay resistance is strong.
For achieving the above object, the technical solution of the utility model is:
A kind of automobile tire steel cord, it comprises internal layer, skin, and internal layer is made up of four steel wires, and skin is made up of six roots of sensation steel wire; What described outer six roots of sensation steel wire was inhomogeneous is arranged in around four steel wires of internal layer, and forms steel cord around four steel wire twistings of internal layer, and the cross section of described steel cord is irregular polygon; Four steel wires of described internal layer are not twisted, outer six roots of sensation steel wire around the sth. made by twisting of four steel wires of internal layer to twist with the fingers for S to.
Further, every monofilament of four steel wires of described internal layer is at a plane internal deformation, and every monofilament of cover wire is out of shape at cylindrical space inside spin.
Again, described outer field wire pitch is 16～24mm, and the steel wire diameter of inside and outside layer is 0.15～0.42mm.
The utility model compared with prior art tool has the following advantages:
1. structural steel cord cross section of the present utility model is irregular polygon, has greatly increased the contact area of sizing material and steel wire, thereby improves the bonding force of cord, further improves tyre life.
2. the diameter of the utility model steel wire of internal layer used and cover wire is identical, and four steel wires are through distortion in advance, and deflection is adjustable, leaves more gap, is convenient to the infiltration of rubber; Four steel wires adopt plane deformation, reduce the suffered shearing force of steel wire, reduce wire broken rate; Four steel wires of the outer incomplete wrapping inner layer of six roots of sensation steel wire, the contact-making surface of increase rubber and cord, is conducive to improve the bonding force between sizing material and steel cord.
3. the loading characteristic of the utility model based on radial tire undertread and designing, simple in structure, one-shot forming, and between steel cord monofilament, be line contact, alleviating the wearing and tearing between monofilament, fatigue performance obviously improves.Compare with multilayer cord, steel cord diameter reduces, and therefore can strengthen density, makes that individual wire is stressed to be reduced, and reduces the stress difference between steel wire and sizing material, reduces the shear stress between rubber and all-steel cord, improves the fatigue performance of tire.
Brief description of the drawings
Fig. 1 is the cross sectional representation of the utility model steel cord one embodiment.
Fig. 2 is the distortion schematic diagram of the utility model cord steel wire of internal layer.
Detailed description of the invention
Referring to Fig. 1, Fig. 2, a kind of automobile tire steel cord of the present utility model, it comprises internal layer 1, skin 2, and internal layer 1 is made up of four steel wires, and outer 2 are made up of six roots of sensation steel wire; What described outer 2 six roots of sensation steel wires were inhomogeneous is arranged in around 1 four steel wires of internal layer, and forms steel cord around 1 four steel wire twistings of internal layer, and the cross section of described steel cord is irregular polygon.
The every monofilament 11 of 1 four steel wires of described internal layer is at a plane internal deformation, and every monofilament of outer 2 steel wires is out of shape at cylindrical space inside spin.
1 four steel wires of described internal layer are not twisted, outer 2 six roots of sensation steel wires around the sth. made by twisting of 1 four steel wires of internal layer to twist with the fingers for S to, the lay pitch is 16～24mm, the steel wire diameter of inside and outside layer 2 is 0.15～0.42mm.
Embodiment
Monofilament is, and to be 0.82wt%, the diameter wire rod that is 5.5mm by carbon content draw, heat treatment, plating, be wetly drawn into the steel wire that diameter is 0.3mm after the operation such as drawing through overdrying.
1 four steel wires of internal layer adopt outer unwrapping wire form, monofilament applies predeformation through a pair of circular arc type with 32 tooth flow of metal devices in drawing process, obtain the monofilament of wave height 0.39mm, in outer 2 six roots of sensation steel wires adopt, unwrapping wire form is through the prefabricated distortion of 15mm cylinder, then be twisted into steel cord, 1 four steel wires of described internal layer are not twisted, and outer 2 six roots of sensation steel wires are around the sth. made by twisting of 1 two steel wires of internal layer to being that S twists with the fingers, and the lay pitch is 18mm.
