Abstract
The utility model discloses a kind of engineering tyre height and extend steel cord, it comprises the strand of four mutual twistings, every root strand comprises a core wire and is stranded in five peripheral steel wire on this core wire, strand twisting direction is identical with the twisting direction of cord, steel wire filament diameter is 0.20-0.30mm, the strand lay pitch is 0.5-0.7 times of the cord lay pitch, is 20-25 times of filament diameter.The utility model height extends steel cord and is used for engineering tyre band bundled layer, has protection carcass, improves the effect of tire impact resistance.
Description
Technical field
The utility model relates to steel cord, and particularly a kind of engineering tyre height extends steel cord.
Background technology
Along with developing rapidly of mining industry, the requirement of mine car to the performance of engineering giant embryo is more and more higher, engineering tyre is frequently used on road conditions mine complicated and changeable, not only lifting capacity and resistance to endurance have a great impact the service life to tire, shock resistance quality is also the key factor of engineering tire length in service life, therefore engineering ride generally has multilayer band bundled layer steel cord, 7 × (3+9+15) series engineering steel cord for tires generally play the effect of load-carrying in band bundled layer, and the high cord that extends can significantly play shock proof effect in band bundled layer.
The steel cord of 3 × 7 traditional series need increase the requirement that filament diameter could meet engineering tire intensity, but corresponding what bring is the reduction of extension, and regular shape, and rubber contact area is little; 4 × 7 Series Steel cords are tight because strand monofilament arranges, and strike-through performance is bad, can not meet engineering tyre performance requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of engineering tyre height to extend steel cord, its have strike-through good, extend high advantage.
For achieving the above object, the technical solution of the utility model is:
A kind of engineering tyre extends steel cord with high, and it comprises the strand of four mutual twistings, and every root strand comprises a core wire and is stranded in five peripheral steel wire on this core wire, and five peripheral steel wire not exclusively wrap core wire.
Further, in described steel cord, 24 steel wire diameter are all identical, and filament diameter is 0.20-0.30mm.
Preferably, described steel cord four strand lay pitch are 0.5-0.7 times of the lay pitch of cord own, are 20-25 times of filament diameter.
Again, the twisting direction of described strand is identical with the twisting direction of steel cord.
In addition, be linear contact lay between strand described in the utility model, combine for linear contact lay and point cantact between steel wire.
The utility model compared with prior art tool has the following advantages:
1. the utility model extension of obtaining wanting by controlling the strand lay pitch, extension control range is 3%-9%, and itself and filament diameter ratio are less, and extension is larger, meets the requirement of different kinds of tyre extension.
2. the utility model strand is made up of a core wire and five peripheral steel wire, and five peripheral steel wire can not wrap core wire completely, are convenient to the infiltration of sizing material, improves bonding force; Simultaneously owing to wrapping up completely, when being in rope between strand, movement can be produced because there being gap between monofilament, present the imagination that linear contact lay and point cantact occur simultaneously, cord surface is coarse, and surface area increases, and improves the contact area with rubber, when ensureing high extension, further increase bonding force.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the utility model embodiment.
Detailed description of the invention
See Fig. 1, a kind of engineering tyre height of the present utility model extends steel cord, it comprises the strand 1 of four mutual twistings, every root strand comprises a core wire 11 and five peripheral steel wire 12 be stranded on this core wire 11 form, twisting direction is identical with the twisting direction of cord, cord 24 filament diameters are all identical, and filament diameter is 0.20-0.30mm.Described steel cord four strand lay pitch are 0.5-0.7 times of the lay pitch of cord own, are 20-25 times of filament diameter.Be linear contact lay between steel cord strand, combine for linear contact lay and point cantact between monofilament.
Embodiment
Monofilament be drawn through overdrying by the wire rod of carbon content to be 0.72wt% diameter be 5.5mm, heat treatment, plating, wet the operation such as to draw after be drawn into the steel wire that diameter is 0.25mm.
Strand 1 internal layer core wire 11 filament diameter 0.25mm, five filament diameter 0.25mm peripheral steel wire 12 are twisted with the fingers with S respectively with lay pitch 14.3mm and are twisted into strand 1 around core wire 11, four strands 1 are twisted into rope with S each other with the lay pitch of 9.5mm, and the Cheng Shenghou strand lay pitch is 5.7.
The steel cord obtained has good extension property, and extension is 5.9%, and this structure cord has higher fracture elongation, and shock resistance is good and rubber adhesion is high, can be applicable to large-scale load-carrying engineering tyre band bundled layer etc.
