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 a
