Abstract

The utility model discloses a super -strength steel wire cord compiles the sth. Made by twisting by super -strength steel wire and forms, including heart yearn thigh, middle strand and outer strand, it divides twice volume sth. Made by twisting to form by 27 super -strength steel wire, and the elder generation is evenly arranged around three steel wires of heart yearn thigh by nine steel wires of middle strand, compiles to twist with the fingers to form middle thigh, is evenly arranged around middle strand by 15 steel wires of outer strand again, 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, middle strand and outer strand to the same, be Z 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

Unimach silk 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；

All-steel cord is the important component part of radial framework material, reduces all-steel cord consumption and can reduce tire drag, and then reduces oil consumption and cost.Under ensureing the premise that cord intensity is constant, the consumption of all-steel cord to be reduced, be necessary for improving all-steel cord intensity.Along with the development need of tire, the strength grade of all-steel cord is developed to the direction of superhigh intensity by the regular tenacity in past, high intensity, and with the light-weighted trend of tire, unimach silk cord demand is gradually increased.

Summary of the invention

The purpose of this utility model is to provide that a kind of superhigh intensity, strike-through performance be good, the deadweight strong, low of corrosion resistance ability, high fatigue resistance unimach silk cord.

This utility model is achieved by the following technical solution:

Unimach silk cord, compiled sth. made by twisting by extra-high strength wire to form, including heart yearn stock, middle strand and outer layer strand, it is compiled sth. made by twisting at twice by 27 extra-high strength wires and forms, first it is evenly spaced in around three steel wires of heart yearn stock by nine steel wires of middle strand, compiling to twist with the fingers and form intermediate strand, then be evenly spaced in around intermediate strand by 15 steel wires of outer layer strand, volume sth. made by twisting Formation cross-section is circular all-steel cord；Described heart yearn stock, middle strand to identical with the sth. made by twisting of the steel wire of outer layer strand, be Z and twist with the fingers.

It is 5.0mm that heart yearn stock compiles the lay pitch D twisted with the fingers, and middle strand compiles the lay pitch D twisted with the fingers₁For 10.0mm, outer layer strand compiles the lay pitch D twisted with the fingers₂For 16.0mm.

Gauge of wire is 0.20mm.

The steel wire of middle strand is not exclusively wrapped up by the steel wire of this utility model outer layer strand, make to leave between steel wire 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 extra-high strength wire 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.

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.

Shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of unimach silk cord, compiled sth. made by twisting by extra-high strength wire to form, gauge of wire is 0.20mm, including heart yearn stock 1, middle strand 2 and outer layer strand 3, it is compiled sth. made by twisting at twice by 27 extra-high strength wires and forms, first it is evenly spaced in around three steel wires of heart yearn stock 1 by nine steel wires of middle strand 2, compile to twist with the fingers and form intermediate strand, it is evenly spaced in around intermediate strand by 15 steel wires of outer layer strand 3 again, compiles and twist with the fingers the all-steel cord that Formation cross-section is circle；Described heart yearn stock 1, middle strand 2 to identical with the sth. made by twisting of the steel wire of outer layer strand 3, be Z and twist with the fingers, and it is 5.0mm that heart yearn stock 1 compiles the lay pitch D twisted with the fingers, and middle strand 2 compiles the lay pitch D twisted with the fingers₁For 10.0mm, outer layer strand 3 compiles the lay pitch D twisted with the fingers₂For 16.0mm.Product specification 3+9+15 × 0.20ST, rugosity 1.240mm, Fracture Force 2866N, line density 6.780g/m, coating weight 4.55g/kg, Cu64.7%.

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.
