Double-drum forming machine for bead core of all-steel radial tire and manufacturing method of bead core

Abstract

The invention discloses a double-drum forming machine for a bead core of an all-steel radial tire. The double-drum forming machine comprises a bead fabric feeding device, a bead filler feeding device, a steel ring transferring device and a forming device, wherein the bead fabric feeding device is mounted on one side of the forming device through a first base and connected with the forming device; the bead filler feeding device and the steel ring transferring device are respectively mounted on the other side of the forming device through a second base and a third base, and both the bead filler feeding device and the steel ring transferring device are connected with the forming device. Meanwhile, the invention further provides a manufacturing method of the bead core adopting the double-drum forming machine for the bead core of the all-steel radial tire. According to the manufacturing method, a bead fabric winding process, a bead filler winding process and a turn-up forming process are integrated, human assistance among the processes is reduced, the automation level of production is improved, and meanwhile the production efficiency is improved.

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
