Gland for all-steel radial tire nitrogen vulcanizing machine central mechanism

Abstract

The invention discloses a gland for an all-steel radial tire nitrogen vulcanizing machine central mechanism. An installation fixing hole is formed in the side wall of a gland main body around a through hole, the installation fixing hole is arranged along the height direction of the gland main body, a gland air cavity is formed in the side wall of the gland main body, and is arranged along the circumference of the gland main body, an inlet and an outlet of the gland air cavity are formed in the bottom wall of the gland main body, and are respectively corresponding to a steam nitrogen inlet channel and a steam nitrogen return channel, exhaust holes are formed in the side wall of the gland main body and are arranged along the thickness direction of the side wall of the gland main body, ejection holes are formed in the side wall of the gland main body and are arranged along the thickness direction of the side wall of the gland main body outside the gland air cavity; an inner opening of the ejection hole is communicated with the gland cover air cavity, and an outer opening of the ejection hole is formed in the outer surface of the side wall of the gland main body, and the ejection direction of the ejection hole is formed by rotating the horizontal direction for 30 DEG to 45 DEG, and the axle downward angle is between 10 DEG to 20 DEG.

Description

technical field [0001] The invention relates to a new accessory for the central mechanism of an all-steel radial tire nitrogen vulcanizer, in particular to a gland for the central mechanism of an all-steel radial tire nitrogen vulcanizer. Background technique [0002] In the past ten years, in order to improve production efficiency, reduce energy consumption, and increase the recycling rate of energy, many tire manufacturers at home and abroad have switched to steam / nitrogen vulcanization process. , and then fill the capsule with 20-26 kg of high-purity nitrogen pressurization method to achieve high temperature and high pressure vulcanization conditions, which not only shortens the vulcanization cycle and reduces energy consumption, but also eliminates the phenomenon of pipeline erosion, saving equipment operation and Maintenance costs and reduced downtime costs. However, most tire manufacturers use the glands uniformly configured by the vulcanizing machine manufacturers fo...

AI Technical Summary

Problems solved by technology

However, most tire manufacturers use the glands uniformly configured by the vulcanizing machine manufacturers for production. This type of gland is mainly used for tire vulcanization in the superheated water process. In order to reduce the cost of the vulcanizer, the height of these glands should be compressed as much as possible. , its design height is only between 20mm and 40mm, and its injection hole has no angle and no direction. When it is used in the nitrogen vulcanization process, the high-pressure saturated steam cools down during the vulcanization process to form condensed water, which accumulates on the lower side of the capsule , due to the low design height, no angle, and no direction of this gland, it cannot drive the condensed water on the lower side of the bladder to enter the circulation system for removal, resulting in uneven temperature of the upper and lower molds and uneven vulcanization. The produced tires cannot fully utilize the tires during use Due to the comprehensive performance of each component, tires are prone to early damage, and most of them are concentrated in the lower mold
