All-steel radial tire bead core double-drum forming machine and bead core manufacturing method

Abstract

The invention discloses an all-steel radial tire bead core double-drum forming machine, comprising a nipple cloth feeding device, an apex rubber feeding device, a steel ring transfer device and a forming device. A base is installed on one side of the forming device, and the sub-mouth wrapping device is connected with the forming device; the apex feeding device and the steel ring transfer device are respectively installed on the other side of the forming device through the second base and the third base. On one side, the triangular feeding device and the steel ring transmission device are both connected with the forming device. At the same time, the present invention also provides a method for manufacturing the bead core of the all-steel radial tire bead core double-drum forming machine. The invention can integrate the sub-mouth wrapping wrapping process, the apex wrapping process and the reverse wrapping forming process into one, reduce manual assistance between each process, improve the automation level of production, and also improve the production efficiency.

Description

technical field [0001] The invention relates to tire bead core manufacturing technology, in particular to an all-steel radial tire bead core double-drum forming machine and a bead core manufacturing method. Background technique [0002] In the tire, the bead core is to firmly fix the tire on the rim, prevent deformation due to inflation pressure and external force, prevent the car from shaking when driving, and ensure the normal driving of the car, so it is a very important part. According to the structure of the tire, the bead core is generally composed of a steel traveler, apex rubber, and a flipper. Flipper, also known as slit wrap, is a fiber or steel ply layer attached to the bead core as a reinforcing layer to strengthen the function of the bead core. It is an essential component of all-steel radial tires . [0003] In the production process of all-steel radial tires, the order of bead core combination is to first attach the apex rubber to the steel traveler wrapped ...

AI Technical Summary

Problems solved by technology

[0003] In the production process of all-steel radial tires, the order of bead core combination is to first attach the apex rubber to the steel traveler wrapped with fiber cord strips, and then attach the reinforcing layer (spigot cloth) to the triangle One side of the rubber and traveler composite part. At present, these two processes need to be completed on different equipment, and the transfer between the two processes is completed by manual assistance, resulting in low production efficiency and large equipment footprint, which is not conducive to Miniaturization and automation of tire production equipment
