Background
Currently, in the field of tire manufacturing, a tire bead includes three parts, a ply, a rim, a chafer, and the like. The tire bead has the function of firmly fixing the outer tire on the rim, so that the outer tire is prevented from being separated from the rim when a vehicle runs, and the outer tire is ensured to be firmly attached to the rim. The bead main body is a steel ring and consists of a steel wire aperture, a filler strip (namely a triangular rubber strip) and a steel wire ring wrapping cloth, wherein the steel wire ring is an aperture made of flat adhesive-coated belts with a plurality of steel wires arranged, the filler strip is attached to the outer ring of the steel wire aperture, and finally the steel wire aperture and the filler strip are tightly wrapped into an integral process by the steel wire ring wrapping cloth. The number of steel wires and the number of layers of the steel wire ring are the total number of steel wire rings required by calculation according to the air pressure standard and specification size required by the structural design of the tire. During production, if the number of the steel wire rings is less than the specified number, the safety strength of the steel wire ring is reduced, and the steel wire is broken; or the number of the steel wires is large, the waste materials can influence the structure of the tire bead, the toe-out phenomenon of the finished product can be generated, and the quality of the outer tire is directly influenced, so that in the manufacturing process of the tire, before the new variety forming tire blank is replaced, the first steel wire is firstly checked, the wrapping cloth wrapped on the outer layer of the steel wire ring is peeled off, the steel wire can be used after the steel wire number is checked and confirmed to meet the technical standard, and otherwise, the hidden trouble of uncertainty exists.
