Abstract
The utility model discloses a kind of 12 strands of high drawing steel cords, compile sth. made by twisting form by steel wire, steel strand is compiled sth. made by twisting by steel wire and is formed, and it is compiled sth. made by twisting by four strand rope stock and forms, and twists with the fingers and twists with the fingers to for S, and the cross section of formation is square; Described steel strand is compiled sth. made by twisting by three steel wires and is formed, and the cross section of formation is triangle.This steel cord percentage elongation is high, can bear larger impact and have higher Fracture Force.
Description
Technical field
The utility model relates to a kind of as the steel cord in pneumatic tire, particularly reduce required steel cord, simultaneously can keep or improve the performances such as the Fracture Force of steel cord and Fracture Force percentage elongation, thus the weight of tire can be reduced, and the steel cord for tire of supply and demand production cost can be reduced.
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 the development of Chinese national economy, the projects such as China's fundamental construction and mining get more and more.Because this type of pavement behavior is comparatively severe, therefore require all very harsh, particularly in the anti-wear performance and impact property of tire to the properties of tire.Tire belt protective layer selects deep drawing quality, high impact-resistant all-steel cord, can contribute to the service life extending tire, improve tyre recapping rate.
Summary of the invention
The purpose of this utility model is to provide a kind of high drawing, high Fracture Force, anti-wear performance are good, accounts for tire weight than little steel cord.
The utility model is achieved by the following technical solution:
A kind of 12 strands of high drawing steel cords, compile sth. made by twisting by steel wire and form, and steel strand is compiled sth. made by twisting by steel wire and formed, and it is compiled sth. made by twisting by four strand rope stock and forms, and twist with the fingers and twist with the fingers to for S, and the cross section of formation is square; Described steel strand is compiled sth. made by twisting by three steel wires and is formed, and the cross section of formation is triangle.
The lay pitch of described steel cord is 9.0mm, and the lay pitch of steel strand is 4.5mm, and the sth. made by twisting of steel strand is twisted with the fingers to for S.
The high-tensile steel wires of described steel wire to be diameter be 0.32mm.
The utility model compared with prior art has following beneficial effect:
1, the utility model steel wire diameter is all consistent, and steel cord material changes into by force high-strength by general, and plying monofilament changes thick specification into by thin specification; Adopt after such scheme, to keep or when improving other performances, line density is lower than general high drawing steel cord, and the reduction of line density is conducive to the lightweight of tire at steel cord; Under equal conditions, the reduction of line density can reduce the manufacturing cost of tire, has price competitiveness.
2, the utility model due to the wire twisting lay pitch little, its percentage elongation is high, therefore it can bear larger impact and have higher fatigue performance.
3, the utility model intensity of steel wire is high, and can keep identical humidification simultaneously, can reduce the weight of cord in tire, reduce tire production cost, increase economic efficiency.
4, in engineering tyre, because high drawing steel cord has good Fracture Force and percentage elongation performance, therefore the utility model can be used for band bundled layer and the protective layer of engineering tyre, can improve the shock resistance of tire.Meanwhile, for production steel cord, high drawing steel cord changes thick specification into by thin specification to be produced, and its production efficiency can get a promotion, board per unit area yield can be improved, simplification of flowsheet, can vertical pulling be realized, reduce process cost, steel cord manufacturing cost is declined, there is market competition advantage.
Accompanying drawing explanation
Fig. 1 is the section structure schematic diagram of the utility model embodiment.
Sequence number in figure: 1, steel wire, 2, steel strand.
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 12 strands of high drawing steel cords, compile sth. made by twisting by the high-tensile steel wires 1 of diameter 0.32mm and form, it is compiled sth. made by twisting by four strand rope stock 2 and forms, and twist with the fingers and twist with the fingers to for S, the lay pitch is 9.0mm, and the cross section of formation is square; Described steel strand 2 is compiled sth. made by twisting by three steel wires 1 and is formed, and twist with the fingers and twist with the fingers to for S, the lay pitch is 4.5mm, and the cross section of formation is triangle.
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.
