Abstract

The utility model discloses a kind of three strands of all-steel cords of 3 × (1+6) structures, the all-steel cord is twisted by the identical steel strand volume of three bursts of structures, the steel strand is uniformly compiled twirl by six roots of sensation peripheral steel wire and is formed on a core wire steel wire, the peripheral steel wire diameter is less than core wire steel wire, and the orientation of the peripheral steel wire and the orientation of steel strand are identical.The all-steel cord intensity of the utility model is high, and diameter is small, and breaking tensile rate is more than 5%, therefore can replace traditional double-layer crown band using the single layer string of a hat, meets the light-weighted requirement of tire.There are biggish gaps between peripheral steel wire and peripheral steel wire in all-steel cord simultaneously, are conducive to the infiltration of rubber, to slow down the friction between steel wire, reduce heat, extend the service life of tire.

Description

A kind of three strands of all-steel cords of 3 × (1+6) structures

Technical field

The utility model relates to all-steel cord technical fields, and in particular to it is a kind of applied to heavy load radial tire 3 × Three strands of all-steel cords of (1+6) structure.

Background technique

0 ° of belt of heavy load radial tire generallys use " 3 × 7 × 0.20HE " steel cord, such steel cord category at present Small in the gap of Compact cord, cord surface, sizing material hardly enters between steel wire gap.And cord dosage is more, manufactured wheel Tire weight.

Utility model content

The purpose of the utility model is to overcome disadvantages of the existing technology, provide three strands of 3 × (1+6) structures of one kind All-steel cord.

To achieve the goals above, the technical solution of the utility model is：A kind of three strands of steel wire curtains of 3 × (1+6) structures Line, the all-steel cord are twisted by the identical steel strand volume of three bursts of structures, and the steel strand is uniformly compiled by six roots of sensation peripheral steel wire Twirl forms on a core wire steel wire, and the peripheral steel wire diameter is less than core wire steel wire, the orientation and steel wire of the peripheral steel wire The orientation of stock is identical.

Further；The peripheral steel wire and the orientation of steel strand are S to twirl.

Further；The lay pitch of the peripheral steel wire is 4mm, and the lay pitch of the steel strand is 7mm.

Further；The core wire steel wire and peripheral steel wire section are circle, and the core wire gauge of wire is 0.23mm, the diameter of the peripheral steel wire are 0.2mm.

Further；The core wire steel wire and peripheral steel wire are all made of the ST material steel wire of superhigh intensity.

The beneficial effects of the utility model：Three bursts of all-steel cord intensity of the 3 of the utility model × (1+6) structure are high, directly Diameter is small, and breaking tensile rate is more than 5%, therefore can replace traditional double-layer crown band using the single layer string of a hat, to reduce steel The usage amount of silk thread alleviates the weight of tire, reduces costs, and meets the light-weighted requirement of tire.All-steel cord simultaneously There are biggish gaps between middle peripheral steel wire and peripheral steel wire, are conducive to the infiltration of rubber, to slow down between steel wire Friction reduces heat, extends the service life of tire.

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Embodiment：

As shown in Figure 1, a kind of three strands of all-steel cords of 3 × (1+6) structures, the all-steel cord are identical by three bursts of structures The volume of steel strand 1 is twisted, and the steel strand 1 is uniformly compiled to twist and be formed on a core wire steel wire 102 by six roots of sensation peripheral steel wire 101, The core wire steel wire 102 and peripheral steel wire 101 are all made of the ST material steel wire of superhigh intensity, the core wire steel wire 102 and periphery 101 section of steel wire is circle, and the diameter of the core wire steel wire 102 is 0.23mm, and the diameter of the peripheral steel wire 101 is 0.2mm, the diameter of the steel strand 1 are 0.63mm, the orientation of the peripheral steel wire 101 and the orientation of steel strand 1 be S to It twists, the lay pitch of the peripheral steel wire 101 is 4mm, and the lay pitch of the steel strand 1 is 7mm.

Embodiment described above is the preferable scheme of the utility model, is not made in any form to the utility model Limitation, on the premise of not exceeding the technical scheme recorded in the claims there are also other variations and modifications.
