Abstract

The utility model discloses a high -tensile steel wire cord compiles the sth. Made by twisting by the high strength steel silk and forms, including heart yearn thigh and outer strand, it is once compiled to twist with the fingers by ten high strength steel silks and forms, and eight steel wires of outer strand are evenly arranged around three steel wires of heart yearn thigh, once compiles sth. Made by twisting formation cross -section and is circular shape steel cord, the sth. Made by twisting of steel wire of heart yearn thigh and outer strand to the same, be S and twist with the fingers. This steel cord intensity is high, the glue permeation performance is good, corrosion resisting property reinforce, low dead weight, fatigue resistance can be good.

Description

High tenacity steel cord
Technical field
This utility model relates to all-steel cord.
Background technology
The intensity that the demand driving of lighter amount tire steel steel for tyre cord silk by market improves constantly, its intensity is also developed to superhigh intensity and very high strength direction by regular tenacity, high intensity, by adopting the steel cord of higher intensity, can ensure that tire is when some strength, the consumption of steel cord in cord can not only be reduced, it also is able to reduce the consumption of sizing material simultaneously, achieve the deadweight reducing tire, thus reducing the resistance to rolling of tire, reach to save oil consumption, and reduce the purpose of CO2 emission.The strength grade of steel wire in steel cord, according to the requirement in ISO17832:2009, the intensity of individual wire can be defined (volume unit: MPa by below equation;Steel wire diameter unit: mm).
Regular tenacity: tensile strength of wire value=3275-2000* steel wire diameter value;
High intensity: tensile strength of wire value=3650-2000* steel wire diameter value;
Superhigh intensity: tensile strength of wire value=4000-2000* steel wire diameter value;
Extra High Strength: tensile strength of wire value=4350-2000* steel wire diameter value;
The modern life and producing, people are increasing to the demand of automobile industry, and this has just driven developing rapidly of tire industry, and tire enterprise also proposes increasingly higher requirement, continually develop high-performance, the tire product of low cost is trend of the times.Belt, as the main stressed member of radial, bears the load of tire about 60%.So adopting high strength steel cord at present, alleviating the weight of middle belt, reducing the production cost of tire, meet the light-weighted requirement of tire, reduce production cost.
Summary of the invention
The purpose of this utility model is to provide that a kind of high intensity, strike-through performance be good, the deadweight strong, low of corrosion resistance ability, high fatigue resistance high tenacity steel cord.
This utility model is achieved by the following technical solution:
High tenacity steel cord, being compiled sth. made by twisting by high-tensile steel wires to form, including heart yearn stock and outer layer strand, it is once compiled sth. made by twisting by ten high-tensile steel wires and forms, eight steel wires of outer layer strand are evenly spaced in around three steel wires of heart yearn stock, once compile and twist with the fingers the all-steel cord that Formation cross-section is circle;Described heart yearn stock to identical with the sth. made by twisting of the steel wire of outer layer strand, be S and twist with the fingers.
The lay pitch D twisted with the fingers compiled by three steel wires of heart yearn stock is 5.0mm, and the lay pitch d twisted with the fingers compiled by the steel wire of outer layer strand is 10.0mm.
The steel wire diameter of heart yearn stock and outer layer strand is 0.20mm.
This utility model outer layer strand adopts eight steel wires, because using high tensile steel wire, can improve the mechanical property of all-steel cord, make tire and can meet or exceed corresponding bearing capacity.The steel wire of heart yearn stock is not exclusively wrapped up by the steel wire of outer layer strand, make between steel wire, to leave more gap, it is easy to the infiltration of rubber, be conducive to improving the bonding force between rubber and all-steel cord, thus avoiding causing corrosion because dampness enters into all-steel cord inside, the infiltration of sizing material simultaneously can effectively limit the relative movement between steel wire and reduce abrasion between steel wire.
This utility model compared with prior art has the advantages that
This utility model adopts the high-tensile steel wires volume sth. made by twisting high and low deadweight of intensity, anti-fatigue performance good;The steel wire of middle strand is not exclusively wrapped up by the steel wire of outer layer strand, makes to leave between steel wire gap, it is simple to the infiltration strike-through performance of rubber is good;Being conducive to improving the bonding force between rubber and all-steel cord, thus avoiding causing corrosion because dampness enters into all-steel cord inside, corrosion resistance ability is strong;The infiltration of sizing material simultaneously can effectively limit the relative movement between steel wire and reduce abrasion between steel wire.Save sizing material and make consumption, it is possible to save the production cost of the energy and client.
Accompanying drawing explanation
Fig. 1 is the section structure schematic diagram of this utility model embodiment;
Fig. 2 is the transversary schematic diagram of Fig. 1.
Sequence number in figure: 1, heart yearn stock, 2, outer layer strand.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Referring to shown in Fig. 1 and Fig. 2, a kind of high tenacity steel cord, compiled sth. made by twisting by high-tensile steel wires to form, including heart yearn stock 1 and outer layer strand 2, the steel wire diameter of heart yearn stock 1 and outer layer strand 2 is 0.20mm, it is once compiled sth. made by twisting by ten high-tensile steel wires and forms, and eight steel wires of outer layer strand 2 are evenly spaced in around three steel wires of heart yearn stock 1, once compiles and twists with the fingers the all-steel cord that Formation cross-section is circle;Described heart yearn stock 1 to identical with the sth. made by twisting of the steel wire of outer layer strand 2, be S and twist with the fingers;The lay pitch D twisted with the fingers compiled by three steel wires of heart yearn stock 1 is 5.0mm, and the lay pitch d twisted with the fingers compiled by the steel wire of outer layer strand 2 is 10.0mm.Product specification 3+8 × 0.20HT, rugosity 0.840mm, Fracture Force 1604N, Breaking elongation 2.07%, line density 2.820g/m, coating weight 4.73g/kg, Cu63.4%, bonding force 1034N, rubber coating rate 95%.
Embodiment is only to facilitate understand the technical solution of the utility model; it is not intended that the restriction to this utility model protection domain; every without departing from any simple modification, equivalent variations and the modification perhaps according to technical spirit of the present utility model, above scheme made in technical solutions of the utility model, all still fall within this utility model protection domain.
