All-steel tyre multi-zone temperature-control vulcanization device

Abstract

The invention relates to a tyre vulcanization device and especially relates to an all-steel tyre multi-zone temperature-control vulcanization device. The all-steel tyre multi-zone temperature-control vulcanization device comprises a vulcanization steam chamber. The vulcanization steam chamber is divided into a seam allowance part annular steam chamber, a tyre side annular steam chamber and a tyre shoulder annular steam chamber from an inner ring to an outer ring. The width of the tyre side annular steam chamber is corresponding to the width of a tyre side of a tyre. The widths of the seam allowance part annular steam chamber and the tyre shoulder annular steam chamber are respectively greater than the widths of a seam allowance part and a tyre shoulder. The seam allowance part annular steam chamber, the tyre side annular steam chamber and the tyre shoulder annular steam chamber are respectively separated by division plates. Two sides of each one of the division plates are provided respectively with a gas inlet and a gas outlet. The all-steel tyre multi-zone temperature-control vulcanization device solves the problem that in order to improve a vulcanization degree of a thick tyre part to a required degree, vulcanization time needs to be prolonged so that a vulcanization degree of a thin tyre part is improved, and thus the all-steel tyre multi-zone temperature-control vulcanization device improves a tyre vulcanization homogenization degree, shortens the total vulcanization time and improves production efficiency.

Description

technical field [0001] The invention relates to a tire curing device. Background technique [0002] The heating method of the hot plate of the vulcanizing machine in the existing vulcanization process is a single steam chamber, and the temperature of the hot plate can only be a single value; due to the large difference in the thickness of the tire shoulder, sidewall and rim, a single heating temperature will result in the same heating time When the inner tire is vulcanized, there is a large difference in the vulcanization degree of these three parts, that is, the heat accumulation amount. When the vulcanization of the thicker parts (shoulder, rim) is guaranteed to be in the optimal range, the vulcanization degree of the thinner parts (sidewall) will be higher, which will reduce the performance of the sidewall and cause adverse effects during tire retreading. The refurbished market has had adverse reactions. Contents of the invention [0003] In order to solve the uneven ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the uneven vulcanization degree of the tire side and improve the overall performance of the tire, the purpose of this invention is to provide a multi-zone temperature-controlled vulcanization device for all-steel tires, which uses three independent steam chambers for heating, so as to facilitate adjustment Heating temperature of tire shoulder, sidewall and bezel
