fig. 2 is a schematic view of the 1+6 structural steel cord of the present invention passing through a stress relieving device.
Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Please refer to fig. 1 and fig. 2 in combination, wherein 1 is a schematic cross-sectional view of a 1+6 structural steel cord of the present invention; fig. 2 is a schematic view of the 1+6 structural steel cord of the present invention passing through a stress relieving device. The utility model relates to a 1+6 structure steel cord, including a heart yearn monofilament 1 and six root facial line monofilaments 2, the intensity level of heart yearn monofilament 1 is greater than the intensity level of six root facial line monofilaments 2, and six root facial line monofilaments 2 once compile into the strand of twisting 3 around heart yearn monofilament 1, and six root facial line monofilaments 2 center on 1 align to grid of heart yearn monofilament, and there is the clearance between six root facial line monofilaments 2 each other, the infiltration of the rubber of being convenient for. Preferably, the cross section of the steel cord is a regular hexagon. The twisted strands 3 form a steel cord after passing through the stress relief means 4. The steel cord has stable structure, good performance and higher glue permeability.
Because the strength grade of the core wire monofilament 1 is greater than that of the six face wire monofilaments 2, if the strength grade of the core wire monofilament 1 is ST and the strength grade of the six face wire monofilaments 2 is HT, the internal stress of the steel cord is reduced by 0.5-1t/m compared with the internal stress of the steel cord in which the core wire monofilament and the six face wire monofilaments are all in the same strength grade after the six face wire monofilaments 2 are twisted around the core wire monofilament 1 for one time. At this time, the stress of the twisted steel cord is relieved by the stress relieving device 4, and the internal stress of the steel cord is reduced by 0.5-1 t/m. Thereby the utility model discloses a steel cord compares in prior art's steel cord not only stable in structure, the functional, and the internal stress is little moreover, can solve the curtain cloth of tire factory production and cut out the hunch limit, guarantees the automatic concatenation of tire factory curtain cloth, improves the lumber recovery of tire factory, reduces tire factory manufacturing cost.
Preferably, the steel cord is an open type steel cord, and a part or all of the core wire filaments 1 and the face wire filaments 2 are deformed into a spiral shape or a wave shape by a deformer. The open type steel cord has good glue permeation performance, and the deformed monofilament braided and twisted steel cord can still ensure certain openness when being subjected to tension applied from the outside, so that the influence of external force on the permeability of the steel cord is reduced.
