Description
Technical field
Steel cord for tire technical field is the utility model is related to, more particularly to a kind of unimach of (4+6) structure
Cord.
Background technology
Steel cord is the important component of radial framework material, and tire rolling can be reduced by reducing all-steel cord dosage
Dynamic resistance, and then reduce oil consumption and cost.On the premise of ensureing that cord intensity is constant, the dosage of all-steel cord is reduced, just
All-steel cord intensity must be improved.With the development need of tire, the strength grade of all-steel cord is by past regular tenacity, height
Intensity develops to the direction of superhigh intensity, and with the light-weighted trend of tire, unimach silk cord demand gradually increases.
Therefore, for the market demand and the development trend of tire, wheel can be made again by developing a kind of performance that can either ensure tire
The steel cord of tire lighting is just into an important problem.
Utility model content
In view of current use demand and the development trend of tire, the purpose of this utility model is to provide a kind of (4+6)
The superhigh intensity steel cord of structure, strike-through performance is good, corrosion resistance ability is strong, puncture-resistant and the weight that can mitigate tire.
To reach the purpose of this utility model, the superhigh intensity steel cord of one kind (4+6) structure of the utility model includes
The cored wire that four superhigh intensity cored wire steel wires are formed, six roots of sensation superhigh intensity cover wire are compiled around four cored wire steel wires of internal layer and are twisted
Type, twist direction is twisted with the fingers for S and internal layer cored wire is without the lay pitch, and internal layer cored wire steel wire assumes diamond in shape arrangement, and the section of the steel cord of formation is oval
Shape；Internal layer cored wire steel wire diameter and cover wire diameter are 0.21mm；And the cover wire compiles what is twisted with the fingers around internal layer cored wire
The lay pitch is 12.0mm.
The beneficial effects of the utility model are that the superhigh intensity steel cord of described (4+6) structure is used for tire belt,
Six roots of sensation steel wire not exclusively wraps up middle cored wire, leaves more gaps, easy to the infiltration of rubber, be conducive to improve rubber with
Bonding force between steel cord, so as to avoid causing corrosion because moisture (moisture) enters inside steel cord；Gauge of wire
It is relatively thin, the dosage of steel wire can be reduced, makes the production cost of steel cord and tire significantly reduce, and the weight of tire is reduced, symbol
Close the development trend of tire for vehicles high-performance and green.
Brief description of the drawings
By detailed description below in conjunction with the accompanying drawings, the utility model is foregoing to incite somebody to action with other objects, features and advantages
Become apparent.Wherein：
Fig. 1 is a kind of structure diagram of the superhigh intensity steel cord of (4+6) structure of the utility model.
Embodiment
The structure of the superhigh intensity steel cord of (4+6) structure of one embodiment of the utility model according to figure 1 is shown
It is intended to, the steel cord includes the cored wire that four superhigh intensity cored wire steel wires 10 are formed, six roots of sensation superhigh intensity cover wire 20
The type that is twisted is compiled around described four cored wire steel wires of internal layer, twist direction is twisted with the fingers for S and internal layer cored wire assumes diamond in shape without the lay pitch, internal layer cored wire steel wire
Arrangement, the section of the steel cord of formation is ellipse；Internal layer cored wire steel wire diameter is equal with cover wire diameter.It is preferable one
In embodiment, the cored wire steel wire diameter and cover wire diameter are 0.21mm.
The utility model is used according to newest《Radial steel cord》National standard (GB/T_11181-
2016) extra-high strength wire as defined in, the intensity of steel wire than the regular tenacity of same diameter improve 20% or so；Steel wire diameter
Small, bend loading, pliability and the fatigue performance of cord also accordingly improve；Twist direction is identical between steel wire, is contacted for line, contact
Area is big, and contact is small, can effectively reduce the abrasion between steel wire.This structure can ensure the situation of carcass intensity
Under, the thickness of cord is reduced, manufactured tire weight is light, and heat is low, and oil consumption is few, saves resources of production and production cost.
In addition, when the steel cord of the utility model carries out twisting, due to the use of the extra-high strength wire of small diameter
Cord, therefore, lay pitch during twisting, the twist direction of different layers steel cord etc. are required for being redesigned accordingly.The lay pitch is big, raw
Yield is high, but fatigue performance declines, this is because when the lay pitch is bigger, the torsional deflection degree of cord monofilament in twisting is just
Smaller, its elastic restoring force is larger, if this elastic restoring force cannot eliminate, can decline the fatigue performance of cord,
Service life shortens；The lay pitch is small, and the fatigue performance of steel cord improves, and elongation is high, but the spinning loss of intensity is big, productivity
Also reduce.So it is that steel cord is ground to carry out rational lay pitch design according to the all-steel cord of varying strength and different steel wire diameters
Important performance characteristic during hair.It is in a preferred embodiment, described outer through experimental verification repeatedly based on above-mentioned consideration
It is 12.0mm that layer steel wire, which compiles the lay pitch twisted with the fingers around internal layer cored wire,.
The superhigh intensity steel cord of (4+6) structure of the utility model is used for tire belt, internal layer cored wire steel wire and outer
Aspect line is all incomplete to middle cored wire using the extra-high strength wire of same diameter, steel wire diameter 0.21mm, six roots of sensation steel wire
Parcel, leaves more gaps, easy to the infiltration of rubber, is conducive to improve the bonding force between rubber and steel cord, so as to keep away
Exempt to cause corrosion because moisture (moisture) enters inside steel cord.The steel cord has preferable impact resistance, wears well
The superior functions such as thorn；In addition, gauge of wire is thinner, the dosage of steel wire can be reduced, cord thickness is smaller, reduces tire production
When strike-through amount so that the production cost of steel cord and the production cost of tire significantly reduce, increase economic efficiency and reduce
The weight of tire, meets the development trend of tire for vehicles high-performance and green.
The utility model is not limited to the embodiment described, and those skilled in the art is not departing from the utility model
Spirit is in the open scope, still be may make some modifications or changes, therefore the rights protection scope of the utility model is with claims
Subject to the scope of restriction.
