Abstract
The utility model discloses a superhigh-strength steel cord for a belted layer. The superhigh-strength steel cord comprises two inner layer steel wires and four outer layer steel wires, the four outer layer steel wires are unevenly distributed around the two inner layer steel wires to be twisted into the steel cord, and the cross section of the steel cord is in an irregular hexagon shape. The tensile strength of the superhigh-strength steel cord is larger than 3900Mpa, the steel cord has the advantages of being good in rubber seepage performance, high in adhesive force and high in corrosion resistance, the weight of tires can be greatly reduced, and production cost is lowered.
Description
Technical field
The utility model relates to the extra-high tensile steel cord that a kind of band bundled layer is used
Background technology
The modern life and produce, people are increasing to the demand of automobile industry, and this has just driven developing rapidly of tire industry, also tire enterprise has been proposed to more and more higher requirement, continually develops out high-performance, tire product is trend of the times cheaply.Band bundled layer, as the main stressed member of radial, has born approximately more than 60% load of tire, so mostly manufacture band bundled layer with the thicker cord of structure in early stage tire, makes the weight of tire very large, and cost is higher.
Existing steel cord mostly is regular texture (such as 3 * 1 series are that equilateral triangle, 1+6 series are regular hexagon), limited the contact area of steel wire and rubber, for double-decker, steel wire of internal layer is owing to being wrapped up completely by cover wire, even cannot directly contact with rubber, reduce bonding force and the strike-through performance of cord.By prefabricated distortion has increased gap and the specific area between steel wire to monofilament, sizing material can be infiltrated into completely; And for irregular cord, can increase the contact area of sizing material and steel wire, improve the bonding force of cord.
Summary of the invention
The extra-high tensile steel cord that provides a kind of band bundled layer to use is provided the purpose of this utility model, there is the advantages such as strike-through performance is good, bonding force is high, decay resistance is strong, and its tensile strength is greater than 3900MPa, to alleviate the weight of band bundled layer in tire, reduce the production cost of tire, meet the light-weighted requirement of tire, reduce production costs.
For achieving the above object, the technical solution of the utility model is:
The extra-high tensile steel cord that a kind of band bundled layer is used, comprise two steel wire of internal layer and four cover wires, inhomogeneous being arranged in around two steel wire of internal layer and around two steel wire of internal layer twistings of described four cover wires forms steel cords, and the cross section of described steel cord is irregular hexagon.
Further, described two steel wire of internal layer are not twisted, four cover wires around the sth. made by twisting of two steel wire of internal layer to for S, twist with the fingers to, the lay pitch of cover wire is 8～20mm.
Again, the diameter of described steel wire of internal layer and cover wire is 0.15～0.38mm.
The monofilament of extra-high tensile steel cord described in the utility model be by carbon content be 0.92wt%, the diameter wire rod that is 5.5mm through overdrying draw, heat treatment, plating, wet to be drawn into diameter after the operation such as drawing be the steel wire that 0.15～0.38mm, tensile strength are greater than 3900MPa.Two steel wire of internal layer are identical with the diameter of four cover wires, wherein, two steel wire of internal layer adopt outer unwrapping wire form to roll prefabricated distortion through 12～15mm circle, in four cover wires adopt, unwrapping wire forms are rolled prefabricated distortion through 3～5mm circle, and then to form cross section be irregular hexagonal extra-high tensile steel cord to twisting.
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 hexagon, 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 cover wires not exclusively wrap up two steel wire of internal layer, leave more gap, are convenient to the infiltration of sizing material, are 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, the tensile strength of steel cord is greater than 3900MPa, belonging to extra-high tensile steel cord, because its intensity height has been realized the lightweight of steel cord, and is line contact between steel cord monofilament, close structure, steel cord diameter reduces, so the use of extra-high tensile steel cord in tire not only alleviated the weight of steel cord, also reduced the consumption of sizing material, thereby reduced the resistance to rolling of tire simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model extra-high tensile steel cord.
The specific embodiment
Referring to Fig. 1, the extra-high tensile steel cord that band bundled layer of the present utility model is used, comprise two steel wire of internal layer 1 and four cover wires 2, inhomogeneous two steel wire of internal layer 1 that are arranged in of described four cover wires 2 form steel cord around and around two steel wire of internal layer, 1 twisting, and the cross section of described steel cord is irregular hexagon.
In the present embodiment, monofilament be by carbon content be 0.92wt%, the diameter wire rod that is 5.5mm through overdrying draw, heat treatment, plating, wet to be drawn into diameter after the operation such as drawing be the steel wire that 0.17mm, tensile strength are greater than 3900MPa.
Two steel wire of internal layer 1 adopt outer unwrapping wire form to roll prefabricated distortion through 15mm circle, in four cover wires 2 adopt, unwrapping wire form is rolled prefabricated distortion through 3mm circle, then be twisted into steel cord, described two steel wire of internal layer 1 are not twisted, four cover wires 2 are around the sth. made by twisting of two steel wire of internal layer 1 to being that S twists with the fingers, and the lay pitch is 10mm.Becoming rope cord winding mode is false twist device after first straightener, prevents from producing fracture of wire because crossing to twist with the fingers, and finally obtains 2+4 * 0.17UT steel cord, and cross section is irregular hexagon, and average tensile strength is 3937MPa.
