Description

Steel cord for engineering tire

Technical field

The utility model relates to a kind of engineering tire steel cord.

Background technology

In recent years, the fast development of China's fundamental construction, the engineering machinery radial tyre demand for the adverse circumstances such as mine, building site constantly increases.Mining area overload of vehicle situation is serious, the situations such as pavement behavior is severe, therefore requires all very harsh to the properties of steel cord for engineering tire.Particularly in bearing capacity, puncture-resistant, endurance, decay resistance aspect.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of bearing capacity is strong, strike-through performance is good, puncture-resistant, corrosion resistance and good, security performance are high, and accounts for tire weight than little engineering tire steel cord.

The utility model is achieved by the following technical solution:

Steel cord for engineering tire, compile sth. made by twisting by steel wire to form, comprise core steel wire strand, pars intermedia steel wire strand and twine steel wire outward, pars intermedia steel wire strand is distributed in around core steel wire strand, twine steel wire winding outward outside pars intermedia steel wire strand, the sth. made by twisting of described core steel wire strand is twisted with the fingers to for S/S, and the sth. made by twisting of pars intermedia steel wire strand is twisted with the fingers to for Z/Z, and the sth. made by twisting twining steel wire is outward twisted with the fingers to for S.

Described core steel wire strand is compiled sth. made by twisting with outer 20 steel wires formed by internal layer steel wire, intermediate layer six roots of sensation steel wire.

Described pars intermedia steel wire strand is six strands of steel wire strands being distributed in around core steel wire strand, per share steel wire strand by internal layer be a steel wire, intermediate layer six roots of sensation steel wire compiles sth. made by twisting with outer 20 steel wires and forms.

Described core steel wire strand, pars intermedia steel wire strand and the carbon content twining steel wire steel wire are outward not less than 0.7%.

The utility model steel cord for engineering tire is compiled by core steel wire strand and the six strands of pars intermedia steel wire strands be wrapped in around core steel wire strand and an additional winding steel wire and is twisted type, and be made up of 134 steel wires altogether, intensity is high, and bearing capacity is strong.Be face contact between steel wire strand, between monofilament, transportable space is flexible strong greatly, and fatigue performance is good.Core steel wire strand and pars intermedia steel wire strand and to twine steel wire be outward ordinary lay, be convenient to strike-through between steel wire strand, rubber can fully penetrate in steel cord, and corrosion resistance and good extends the service life of tire.

The utility model compared with prior art has following beneficial effect:

1, the utility model is by improving the mechanical property of silk thread, reduces silk thread consumption, thus reduces tire weight, reduces production cost;

2, the utility model intensity is high, and bearing capacity is strong; Be face contact between steel wire strand, between monofilament, transportable space is flexible strong greatly, and fatigue performance is good, and security performance is good; Core steel wire strand and pars intermedia steel wire strand and to twine steel wire be outward ordinary lay, be convenient to strike-through between steel wire strand, rubber can fully penetrate in steel cord, and puncture-resistant, corrosion resistance and good extend the service life of tire.

Accompanying drawing explanation

Fig. 1 is the section structure schematic diagram of the utility model embodiment.

Sequence number in figure: 1, core steel wire strand, 2, pars intermedia steel wire strand, 3, twine steel wire outward.

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 Figure 1, a kind of steel cord for engineering tire, compile sth. made by twisting by steel wire and form, the carbon content of steel wire is not less than 0.7%, and its cross section is that circle specifically comprises core steel wire strand 1, pars intermedia steel wire strand 2 and twines steel wire 3 outward; Described core steel wire strand 1 is compiled sth. made by twisting with outer 20 diameter 0.225mm steel wires formed by internal layer diameter 0.25mm steel wire, intermediate layer six roots of sensation diameter 0.225mm steel wire, the sth. made by twisting of core steel wire strand 1 is twisted with the fingers to for S/S, it is 8.0mm that wire of intermediate layer compiles the lay pitch of twisting with the fingers, and it is 16.0mm that cover wire compiles the lay pitch of twisting with the fingers; Described pars intermedia steel wire strand is six strands of steel wire strands being distributed in around core steel wire strand 1, per share steel wire strand is compiled sth. made by twisting with outer 20 diameter 0.225mm steel wires formed by internal layer diameter 0.25mm steel wire, intermediate layer six roots of sensation diameter 0.225mm steel wire, the sth. made by twisting of pars intermedia steel wire strand 2 is twisted with the fingers to for Z/Z, it is 8.0mm that wire of intermediate layer compiles the lay pitch of twisting with the fingers, and it is 16.0mm that cover wire compiles the lay pitch of twisting with the fingers; The described outer diameter twining steel wire 3 is 0.225mm, and the lay pitch is 5.0mm, twists with the fingers and twist with the fingers to for S.

Embodiment is just for the ease of understanding the technical solution of the utility model; do not form the restriction to the utility model protection domain; every do not depart from technical solutions of the utility model interior perhaps above scheme is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong within the utility model protection domain.
