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+3) structure
Cord.
Background technology
Along with tire low-rolling-resistance and the growth requirement of long life, this requires its framework material guiding principle cord
Intensity is very high, and its Fracture Force, shock resistance and endurance life can be improved by improving steel cord intensity under normal circumstances.With height
By force, general strong steel cord is compared, and under same intensity, can save the steel cord in Tire production and rubber makes super-high strength steel cord
Dosage, so as to reduce rolling resistance during tire is exercised.Therefore, strike-through performance is good, corrosion resistance ability is strong, puncture-resistant and lighting
Steel cord for tire is just into the development trend of steel cord for tire.
Utility model content
In view of current industry use demand, the purpose of this utility model provides a kind of corrosion-resistant, puncture-resistant superior performance
And the superhigh intensity steel cord of (4+3) structure of tire weight mitigation can be made.
To reach the purpose of this utility model, the superhigh intensity steel cord of (4+3) structure of the present utility model includes internal layer
The cored wire that forms of four extra-high strength wires 10 and compile three of the uneven arrangement twisted with the fingers around four cored wire steel wires of internal layer
Outer layer extra-high strength wire 20, internal layer cored wire assume diamond in shape arrangement, and cover wire compiles that the twist direction twisted with the fingers is twisted with the fingers for S and internal layer cored wire is non-twist
Away from Formation cross-section is the steel cord of irregular shape；The internal layer cored wire steel wire diameter is equal with cover wire diameter；Described
Internal layer cored wire steel wire diameter and a diameter of 0.25mm of cover wire；Described internal layer cored wire compiles the lay pitch twisted with the fingers with cover wire
14.0mm。
The beneficial effects of the utility model are the superhigh intensity steel cords of described (4+3) structure, internal layer cored wire and outer layer
Upper thread all uses same diameter steel wire, and intensity of steel wire is that superelevation is strong, has more excellent impact resistance, puncture-resistant etc. superior
Performance, strike-through performance is good, corrosion resistance ability is strong；The steel cord of this structure is used for tire belt, can mitigate tire weight, section
About sizing material usage amount, the production cost of the energy and tiremaker can be saved, is increased economic efficiency.
Brief description of the drawings
By detailed description below in conjunction with the accompanying drawings, the foregoing and other objects, features and advantages of the utility model will
Become apparent.Wherein：
Fig. 1 show a kind of structural representation of the superhigh intensity steel cord of (4+3) structure of the present utility model；
Fig. 2 show the lay pitch schematic diagram of Fig. 1 steel cord.
Embodiment
Shown in reference picture 1 and Fig. 2, the superhigh intensity steel cord of (4+3) structure of an embodiment of the present utility model includes
The uneven arrangement that cored wire that four extra-high strength wires 10 of internal layer are formed and being compiled around four cored wire steel wires of internal layer is twisted with the fingers
Three outer layer extra-high strength wires 20, internal layer cored wire assume diamond in shape arrangement, cover wire compile the twist direction twisted with the fingers twisted with the fingers for S and internal layer cored wire without
The lay pitch, Formation cross-section are the steel cord of irregular shape；And internal layer cored wire steel wire diameter is equal with cover wire diameter.It is excellent one
In the embodiment of choosing, described internal layer cored wire steel wire diameter and a diameter of 0.25mm of cover wire.
The utility model has used the unimach silk cord of small diameter to carry out twisting, therefore, lay pitch during twisting,
Twist direction of different layers steel cord etc. is required for being redesigned accordingly.The lay pitch is big, and productivity ratio is high, but under fatigue performance
Drop, this be due to when the lay pitch is bigger, the torsional deflection degree of cord monofilament in twisting with regard to smaller, its elastic restoring force compared with
Greatly, it if this elastic restoring force cannot eliminate, can decline the fatigue performance of cord, service life shortens；The lay pitch is small,
The fatigue performance of steel cord improves, and elongation is high, but the spinning loss of intensity is big, and productivity ratio also reduces.So according to difference
It is the important performance in steel cord R＆D process that the all-steel cord of intensity and different steel wire diameters, which carry out rational lay pitch design,
Parameter.In addition, arrangement of the steel cord in twisting is the cross sectional shape of internal layer cord and outer layer cord for its strike-through
Can there are important influence, and important Consideration.In a preferred embodiment, the internal layer cored wire and outer layer
It is 14.0mm that steel wire, which compiles the lay pitch twisted with the fingers,.
The steel cord of (4+3) structure of the present utility model is semi-open type structure, and cored wire steel wire and cover wire use root
According to newest《Radial steel cord》Extra-high strength wire as defined in national standard (GB/T_11181-2016), than phase
Intensity of steel wire with the regular tenacity of diameter improves 20% or so；Steel wire diameter is small, the bend loading of cord, pliability and resistance to tired
Labor performance also accordingly improves；Twist direction is identical between steel wire, is linear contact lay, and contact area is big, and contact is small, can effectively reduce steel
Abrasion between silk.This structure in the case where ensureing carcass intensity, can reduce the thickness of cord, manufactured tire weight
Amount is light, and heat is low, and oil consumption is few, saves the resources of production and production cost.Three cover wires are not exclusively wrapped up the cored wire of centre,
More gaps are left, are easy to the infiltration of rubber, is advantageous to improve the bonding force between rubber and steel cord, avoids adverse circumstances
Middle moisture is penetrated between the steel wire of steel cord, is caused when tire is bent repeatedly, and steel cord institute is issuable to accelerate corruption
Erosion problem.
The utility model is not limited to described embodiment, those skilled in the art do not depart from it is of the present utility model
In the i.e. open scope of spirit, it can still make some amendments or change, therefore rights protection scope of the present utility model is with claims
The scope of restriction is defined.
