Abstract
The utility model discloses a twenty-eight-strand steel cord provided with an external spiral wire. The steel cord comprises a cord body and an external spiral steel wire winded outside the cord body; the cord body comprises seven entwisted steel wire strands whose section is square; and each steel wire strand comprises four single entwisted wires. The line contact is positioned among the single wires and the steed wire strands; the mutual entwisting is positioned among the steel wire strand, the cord body and the external spiral wire; and the steel cord is provided with high bearing capacity, puncture bearing and good bleed-through and corrosion resisting performance.
Description
Technical field
The utility model relates to a kind of with the outer 20 stereotyped writing steel cords that twine silk.
Background technology
Along with developing rapidly of highway, the performance requirement of tire is also constantly improving, the carcass that require light card, heavily blocks has corresponding bearing capacity and resistance to persistence energy, pneumatic tire is had higher requirement with the steel cord, must improve bearing capacity, strike-through performance and the decay resistance etc. of steel cord.
Summary of the invention
The 20 stereotyped writing steel cords that the utility model provides that a kind of bearing capacity is strong, the band of puncture, strike-through and corrosion resistance and good twines outward thread.
The technical solution of the utility model is as follows: the outer 20 stereotyped writing steel cords that twine silk of band, it is by the cord body and be wrapped in the external outer winding steel wire of cord and form, described cord body is foursquare steel strand volume sth. made by twisting by seven cross sections and forms, and every steel strand is compiled to twist with the fingers by four monofilament and formed.
In the utility model, between the monofilament, be line contact between the steel strand; Steel strand, cord body and outer winding steel wire are ordinary lay, and promptly they are twisted with the fingers to opposite successively.
After adopting as above technical scheme, the cord body is made up of seven steel strands, and every steel strand is made up of four monofilament again, has 28 monofilament, intensity height, the corresponding raising of bearing capacity.Between the monofilament, be line contact between the steel strand, so the abrasion phenomenon is very little, fatigue performance is good.Between steel strand, cord body and the outer winding steel wire is ordinary lay, easy strike-through between the steel strand, and rubber can fully be penetrated in the steel cord, and corrosion resistance is strong, has prolonged the service life of tire.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 twines the schematic cross-section of 20 stereotyped writing steel cords of silk outward for the utility model band.
The specific embodiment
Embodiment: according to shown in Figure 1, the utility model band twines 20 stereotyped writing steel cords of silk outward, by the cord body be wrapped in the external outer winding steel wire of cord and form.The cord body is compiled to twist with the fingers by seven steel strands and is formed, sth. made by twisting to be Z to, the lay pitch is 20mm.Described steel strand is compiled to twist with the fingers by four diameters monofilament that is 0.175mm and is formed, twist with the fingers to be S to, the lay pitch is 10mm, the cross section of steel strand is square.The diameter of described outer winding steel wire is 0.15mm, twist with the fingers to be S to, the lay pitch is 3.5mm.Between the monofilament, be line contact between the steel strand.
Claims (3)
1, a kind of with the outer 20 stereotyped writing steel cords that twine silk, it is by the cord body and be wrapped in the external outer winding steel wire of cord and form, it is characterized in that described cord body is foursquare steel strand volume sth. made by twisting by seven cross sections and forms, every steel strand is compiled to twist with the fingers by four monofilament and is formed.
2, band according to claim 1 twines 20 stereotyped writing steel cords of silk outward, it is characterized in that between the monofilament, is the line contact between the steel strand.
