Initial point fixing device of steel wire coil winding machine

Abstract

The invention provides an initial point fixing device of a steel wire coil winding machine. A slip ring comprises an inner ring, an outer ring and a connecting plate, wherein the inner ring is arranged in the outer ring, the inner ring and the outer ring are concentrically arranged, the connecting plate is connected between the inner ring and the outer ring, and an outer ring notch is formed in the outer edge of the outer ring. A sliding block comprises a base plate, a set screw, roller pins and bearings, wherein the roller pins are arranged at the two ends of the base plate, the horizontally-installed bearings are arranged at the lower portions of the roller pins, bearing installing holes perpendicular to the base plate are formed in the plate face of the base plate, and the bearings are arranged in the bearing installing holes. The set screw is arranged on the plate face of the base plate. The inner ring is provided with an inner ring track, and the outer ring is provided with an outer ring track. The inner ring track on the inner ring and the outer ring track on the outer ring are symmetrically arranged. The bearings on the base plate are in rolling connection with the inner ring track and the outer ring track correspondingly. Openings are formed in the same positions of the inner ring and the outer ring. The position, corresponding to the inner ring track and the outer ring track, of the lower portion of the connecting plate is provided with a connecting plate notch.

Description

technical field [0001] The invention relates to a starting point fixing device of a bead ring winding machine, which belongs to the technical field of the starting point fixing device of the winding machine. 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 made 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 special-shaped. The steel wires in the traveler are straight and basically mutually Parallel, rubber is filled between steel wires. Shearing force is easily generated between the steel wires of such bead rings. When the tires made of such bead rings are used under high internal pressure, high load, large deformation and strong impact load, it is easy to break in the bead ring or the steel wire. Dela...

AI Technical Summary

Problems solved by technology

Shearing force is easily generated between the steel wires of such bead rings. When the tires made of such bead rings are used under high internal pressure, high load, large deformation and strong impact load, it is easy to break in the bead ring or the steel wire. Delamination or cord breakage occurs between the filler strip and the ply interface

[0003] The existing traveler is all made by the traveler winding machine, but the starting point cannot be quickly positioned when the existing traveler winding machine makes the traveler, and some preparations are required before making the traveler, which increases the production time of the traveler. The production of the traveler is limited to a certain extent
