Tire curing bladder leakage detection method

Abstract

The invention relates to a tire curing bladder leakage detection method, and belongs to the technical field of tire production and processing, a pressure difference value is calculated for each time of pressure maintaining detection, and if the pressure difference value exceeds a preset first pressure threshold value, pressure alarm is carried out to realize detection of bladder rupture leakage, therefore, the phenomenon of continuous waste caused by capsule breakage is avoided, economic losses are reduced, meanwhile, second-time pressure maintaining detection is conducted at intervals, the pressure difference value of the first-time pressure maintaining detection and the pressure difference value of the third-time pressure maintaining detection are taken to calculate the pressure maintaining pressure difference value, if the pressure maintaining pressure difference value exceeds a preset second pressure threshold value, pressure alarming is conducted, and when the capsule leaks slightly, the phenomenon that whether the capsule leaks or not cannot be judged through the pressure difference value of each time of pressure maintaining detection is avoided, and the detection precision is improved.

Description

Technical field [0001] The present invention belongs to the field of tire production and processing, and in particular, to a leak detection method for tire vulcanization capsules. Background technique [0002] Tire sulfurized capsules (referred to as capsules) is a hollow thin-walled rubber article, during the vulcanization molding process of tires, mounted inside the tire vulcanizing machine as a tire stereotype. Inside the capsules, the capsule is filled into fluid media such as overheating water or compressed air, so that the capsule is extended to the tire embryo, which is combined with the tire fetal, using the flow heat transfer characteristics of the internal fluid medium in the capsule, and maintains the temperature in the tire vulcanization. Balanced, achieving a uniform effect of tires, and improves the balance of tires. However, the capsule is prone to damage during the actual use. Once the capsule leaks, the internal medium fluid will leak between the capsule and the ...

AI Technical Summary

Problems solved by technology

However, the capsule is prone to damage during actual use. Once the capsule leaks, the internal medium fluid will leak between the capsule and the embryo, which is difficult to be found, resulting in continuous waste products in subsequent production, causing serious economic losses.
