Device for confirming bending angle of tire steel wire

The utility model relates to a device for confirming the bending angle of a tire steel wire, which comprises an X-ray inspection machine and a sample plate body, the sample plate body is positioned on the sidewall of a tire, the length direction of the sample plate body is perpendicular to a tire bead of the tire, the X-ray inspection machine emits X-rays to the sample plate body, the middle of the sample plate body is a measuring area, and the measuring area is positioned in the measuring area. The sample plate body is provided with a measuring area, the measuring area is provided with a plurality of parallel and spaced measuring grooves, included angles exist between the measuring grooves and the length direction of the sample plate body, and the area between the measuring area and the periphery of the sample plate body is a fixed area. The detection precision and the inspection capability of the turn-up angle of the finished tire are improved, and the probability of quality problems of tires flowing into t
