Abstract
The utility model discloses a kind of ripply steel cord of band, steel cord ontology is twisted by two core wire steel wire volumes, and the orientation of core wire steel wire is S twirl；Core wire steel wire uses tooth form anamorphoser to carry out deformation process in advance, and it is 18~22mm that the volume of steel cord ontology, which twists pitch d1, and core wire steel wire bent wave crest is W/M shape；Core wire steel wire diameter is 0.28~0.32mm, and the gap 0.1~0.3mm is equipped between core wire steel wire, this body section of steel cord is ellipse band corrugated appearance.The utility model can improve the impact property of tire, and steel cord strength grade is got higher, and under equal conditions, can reduce tyre production quality, and steel cord elongation and Fracture Force improve, and can reduce Tire production cost and meet the lightweight requirements of tire.Since the lay pitch is big between steel wire, curved special wave crest is formed, steel cord elongation index is greatly improved, is conducive to the infiltration of rubber, extend the service life of tire.
Description
Technical field
The utility model relates to steel cord technical field, in particular to a kind of ripply steel cords of band.
Background technique
Belt is the main stressed member of radial, periodically bears the deformations such as stretching, bending, shearing and answers
Power.Belt plays an important role to the safety of tire, comfort, high speed performance and endurance quality, although these performances with
Belt severing angle, width and steel cord arranging density are related, but the closest with the property relationship of steel cord.Banding
Layer steel cord only has intensity with higher, higher strike-through, fatigue performance, can just help to improve the property of belt
Can, and then improve tire quality.
Under competitive pressure, cost efficiency is also the requisite measure of tire enterprise seeking development in the market, limited resources
Saving use brought into schedule by manufacturing industry.Therefore, as the steel cord of tyre framework material constantly receive performance, cost with
The challenge of energy conservation, therefore a kind of tire steel cord of intensity lightweight requirements that are high, at low cost and meeting tire is provided.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technological deficiency, provides a kind of ripply steel curtain of band
Line.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of ripply steel cord of band, packet
Steel cord ontology is included, the steel cord ontology is twisted by two core wire steel wire volumes, and the orientation of the core wire steel wire is S
It twists；
The core wire steel wire carries out deformation process using tooth form anamorphoser in advance, and the volume of the steel cord ontology is twisted
Pitch d1 is 18~22mm, and the bending wave crest of the core wire steel wire is W/M shape；
The core wire gauge of wire is 0.28~0.32mm, is equipped with 0.1~0.3mm's between the core wire steel wire
Gap, the section of the steel cord ontology are ellipse band corrugated appearance.
As an improvement, the core wire gauge of wire is 0.3mm.
As an improvement, it is 20mm that the volume of the steel cord ontology, which twists pitch d1,.
As an improvement, the diameter d2 of the steel cord ontology is 0.62mm.
As an improvement, the gap between the core wire steel wire is 0.2mm.
The utility model compared with prior art the advantages of be: the utility model can improve the impact property of tire, steel
Cord strength grade is got higher, and is increased to ST by NT, under equal conditions, can reduce tyre production quality, and steel cord extends
Rate and Fracture Force improve, and can reduce Tire production cost and meet the lightweight requirements of tire.Due to the lay pitch between steel wire
Greatly, curved special wave crest is formed, steel cord elongation index is greatly improved, is conducive to the infiltration of rubber, extend wheel
The service life of tire.
Detailed description of the invention
Fig. 1 is a kind of schematic cross-section of the ripply steel cord of band of the utility model.
Fig. 2 is a kind of side schematic view of the ripply steel cord of band of the utility model.
Cord index contrast table before Fig. 3 is the utility model and improves.
It is as shown in the figure: 1, steel cord ontology；2, core wire steel wire.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
The ripply steel cord of a kind of band combined with Figure 1 and Figure 2, including steel cord ontology 1, the steel cord ontology 1 by
Two volumes of core wire steel wire 2 are twisted, and the orientation of the core wire steel wire 2 is S twirl；The core wire steel wire 2 uses tooth in advance
Deformation device carries out deformation process, and it is 18~22mm, the core wire steel wire 2 that the volume of the steel cord ontology 1, which twists pitch d1,
Bending wave crest be W/M shape；The diameter of the core wire steel wire 2 is 0.28~0.32mm, is set between the core wire steel wire 2
There is the gap of 0.1~0.3mm, the section of the steel cord ontology 1 is ellipse band corrugated appearance, the core wire steel wire 2
Diameter be 0.3mm, it is 20mm that the volume of the steel cord ontology 1, which twists pitch d1, and the diameter d2 of the steel cord ontology 1 is
0.62mm, the gap between the core wire steel wire 2 are 0.2mm.
The utility model in the specific implementation, in conjunction with Fig. 3 (the utility model and improve before cord index contrast table), from table
In can be seen that, the utility model 0230HT (OC) steel cord line density lower than 0230HT can in the case where same volume dosage
Reduce cord thickness and steel cord dosage.Compared with 0230HT, the utility model 0230HT (OC) elongation is high, fatigue durability
Height enhances the shock resistance of belt to the good penetrability of rubber；Equivalent specifications steel cord rugosity is constant and line density not
Become, the lay pitch increases the weight saving of same volume steel wire, reduces Tire production cost and meets the lightweight requirements of tire.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
