Two-stage four-drum forming machine for all-steel truck radical tires

Abstract

The invention relates to a two-stage four-drum forming machine for all-steel truck radical tires, which is characterized by being composed of a first-section forming machine and a second-section forming unit, wherein the first-section forming machine comprises a truss, a first-section tire-body attaching drum, a feeding rack mechanism, a tire-body transfer ring, a first-section forming drum host and a tire-body tube transfer carriage; and the truss is of an inverted U-shaped structure, the first-section tire-body attaching drum and the tire-body transfer ring are sequentially arranged on a cross beam above the truss, a tire-body attaching drum transmission case and a set of tire-body rolling device are arranged in the first-section tire-body attaching drum, the first-section forming drum host comprises left and right reverse packing devices, left and right forward packing devices, a first-section forming drum and rear compression roller device, and a first-section forming drum tail seat, and the left and right reverse packing devices are arranged below the truss. According to the invention, a two-stage four-drum forming machine for all-steel truck radical tires is specially used for producing loaded all-steel radial tires with large bearing, and can achieve an extremely good effect on solving heavy load and seam allowance problems.

Description

technical field [0001] The invention relates to a tire building machine, in particular to a two-stage four-drum building machine for all-steel radial truck tires. Background technique [0002] As one of the most important equipment for manufacturing all-steel radial truck tires under the continuous development of my country's expressway and transportation industry, the all-steel truck radial tire building machine has been greatly developed. At present, the two-drum molding machine and the three-drum molding machine commonly used in the market are one-shot molding machines, and the production efficiency of the two-drum molding machine is low; while the three-drum molding machine commonly used by domestic tire companies has processing accuracy, installation accuracy, and Repeated positioning accuracy is difficult to guarantee and other issues. Although the three-drum molding machine has made a major breakthrough in production efficiency, it has entered a bottleneck in the qua...

AI Technical Summary

Problems solved by technology

At present, in the all-steel radial tire market, the all-steel one-step three-drum building machine is dominant. Compared with the all-steel one-step two-drum building machine, the forming efficiency is greatly improved, but in the actual use of low speed and heavy load, one-step forming Machine-formed all-steel radial tires have exposed serious problems such as poor tread wear resistance and easy bursting of rims, especially in poor road conditions such as mines, which have been unable to overcome, seriously affecting the service life of tires and driving The safety of passengers, due to the high cost of tire repair or recycling, it causes a huge waste of resources

This problem cannot be completely solved by the current one-step forming process and one-step forming machine. Therefore, major improvements and innovations must be made to the forming process and forming equipment of all-steel radial truck tires.
