Bead ring positioning, clamping and turning device of bead ring winding machine

Abstract

The invention discloses a bead ring positioning, clamping and turning device of a bead ring winding machine and belongs to the technical field of rotating devices. Three or four pairs of helper rolls are arranged on a rear machine plate, an arc-shaped steel plate is fixed on the lower side of the front part of the rear machine plate, a driving roller is respectively mounted at the two ends of the arc-shaped steel plate, a lifting screw is arranged at the rear part of the rear machine plate, a driving roller driving motor is fixed at the rear part of the rear machine plate, the output shaft of the driving roller driving motor is in drive connection with one driving roller, a tooth-shaped belt is in drive connection with two driving rollers, a pressure roller rack is arranged on the lower side of the arc-shaped steel plate, a pressure roller is arranged on the pressure roller rack, and the lower end of the pressure roller rack is connected with a hydraulic cylinder. The bead ring positioning, clamping and turning device provided by the invention has a simple structure, and is easier to produce and manufacture. The rotating directions of the wires in the inner and the outer layers of the wound bead ring are opposite, the wire on one layer rotates left and the wire on the other layer rotates right, rubber is not required to be filled between the wires, shearing force is not be produced, and the device can be directly used in tire manufacture.

Description

technical field [0001] The invention relates to a bead ring positioning, clamping and rotating device of a bead ring winding machine, which belongs to the technical field of rotating devices. Background technique [0002] In the field of tire production, in order to enhance the overall support rigidity and reliability of the tire, it is necessary to have a steel traveler inside the tire. The traveler produced by the existing traveler winding machine is formed by winding a steel wire in the forward direction, and its cross-section is usually hexagonal or polygonal or irregular. The steel wires are straight and basically parallel to each other. Rubber is filled between the steel wires. Shearing force is easily generated between the steel wires of such bead rings, and when tires made of such bead rings are used under high internal pressure, high load, large deformation and extremely strong impact load, it is easy to be in the bead ring or filling Delamination or cord breakage...
