Abstract
The utility model discloses a kind of semi-open structural steel cord, compile sth. made by twisting by steel wire to form, it is arranged in around four internal layer heart yearns by three cover wires are uneven, compile sth. made by twisting around internal layer heart yearn to form, described cover wire not exclusively wraps up internal layer heart yearn, Formation cross-section is erose all-steel cord, and described internal layer heart yearn is that four steel wires assume diamond in shape arrangement.This steel cord cover wire not exclusively wraps up internal layer heart yearn, leaves more gap, is convenient to the infiltration of rubber, is conducive to improving the bonding force between rubber and steel cord, thus avoids because moisture enters into steel cord inside and cause corrosion; It is compiled sth. made by twisting by half-shadow high tensile steel wire and forms, and also has the superior functions such as good impact resistance, puncture-resistant; Outer adopt three, monofilament, internal layer heart yearn is that four steel wires assume diamond in shape arrangement, and this structure can alleviate tire weight, and saving sizing material use amount, economize energy, significantly can reduce production cost, increase economic efficiency.
Description
Technical field
The utility model relates to the steel cord that in pneumatic tire, band bundled layer uses.
Background technology
The intensity that the demand driving of market to more lightweight tire steel steel for tyre cord silk improves constantly, its intensity also by regular tenacity, high strength to superhigh intensity and very high strength future development, by adopting the steel cord of more high strength, can guarantee that tire is when some strength, the consumption of steel cord in cord can not only be reduced, also can reduce the consumption of sizing material simultaneously, achieve the deadweight reducing tire, thus reduce the resistance to rolling of tire, reach saving oil consumption, and reduce the object 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 define (volume unit: MPa by following formula; Steel wire diameter unit: mm).
Regular tenacity: tensile strength of wire value=3275-2000* steel wire diameter value;
High strength: 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;
Along with tire low-rolling-resistance and the growth requirement of long life, this just requires that its framework material guiding principle cord strength is high, improves steel cord strength under normal circumstances and can improve its Fracture Force, shock resistance and endurance life.Compared with strong with superelevation, high-strength, general strong steel cord, half-shadow high-strength steel cord, under same intensity, can save the steel cord in Tire production and rubber use amount, thus reduces resistance to rolling in tire enforcement.Half-shadow high tensile steel wire noun uses comparatively partially general in Korea S, still extra-high strength wire is claimed in China or American-European countries, but the intensity of half-shadow high tensile steel wire is relatively also comparatively not good enough relative to the intensity of extra-high strength wire, both the steel wire wire rod of phosphorus content 92% controls its intensity by different heat treatment, wet drawing.
Summary of the invention
The utility model provides that a kind of strike-through performance is good, corrosion resistance ability is strong, the semi-open structural steel cord of puncture-resistant
The utility model is achieved by the following technical solution:
Semi-open structural steel cord, compile sth. made by twisting by steel wire to form, it is arranged in around four internal layer heart yearns by three cover wires are uneven, compile sth. made by twisting around internal layer heart yearn to form, described cover wire not exclusively wraps up internal layer heart yearn, Formation cross-section is erose all-steel cord, and described internal layer heart yearn is that four steel wires assume diamond in shape arrangement.
Described cover wire is twisted with the fingers around the sth. made by twisting of internal layer heart yearn to for S, non-twist distance between described internal layer heart yearn steel wire.
It is 18.0mm that described cover wire compiles the lay pitch of twisting with the fingers around internal layer heart yearn.
Described cover wire and internal layer heart yearn are half-shadow high tensile steel wire, and diameter is all 0.35mm.
The utility model compared with prior art has following beneficial effect:
The utility model cover wire not exclusively wraps up internal layer heart yearn, leaves more gap, is convenient to the infiltration of rubber, is conducive to improving the bonding force between rubber and steel cord, thus avoids because moisture enters into steel cord inside and cause corrosion; It is compiled sth. made by twisting by half-shadow high tensile steel wire and forms, and also has the superior functions such as good impact resistance, puncture-resistant; Outer adopt three, monofilament, internal layer heart yearn is that four steel wires assume diamond in shape arrangement, and this structure can alleviate tire weight, and saving sizing material use amount, economize energy, significantly can reduce production cost, increase economic efficiency.
Accompanying drawing explanation
Fig. 1 is the section structure schematic diagram of the utility model embodiment.
Sequence number in figure: 1, cover wire, 2, internal layer heart yearn.
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 semi-open structural steel cord, compile sth. made by twisting by steel wire to form, it is arranged in around four internal layer heart yearns 2 by three cover wires 1 are uneven, compile sth. made by twisting around internal layer heart yearn 2 to form, described cover wire 1 pair of internal layer heart yearn 2 not exclusively wraps up, and Formation cross-section is erose all-steel cord, and described internal layer heart yearn 2 is that four steel wires assume diamond in shape arrangement; Described cover wire 1 is twisted with the fingers around the sth. made by twisting of internal layer heart yearn 2 to for S, non-twist distance between described internal layer heart yearn 2 steel wire, and it is 18.0mm that described cover wire 1 compiles the lay pitch of twisting with the fingers around internal layer heart yearn 2; Described cover wire 1 and internal layer heart yearn 2 are half-shadow high tensile steel wire, and diameter is all 0.35mm.
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.
