Description

Curing bladder detection device

Technical Field

The utility model relates to a vulcanization capsule detection device.

Background

The tire vulcanizing capsule is a hollow thin-wall rubber product of a tire vulcanizing machine, is filled into an inner cavity of a tire blank to be vulcanized, is filled with a heating medium, and is matched with the vulcanizing machine for shaping and vulcanizing. The curing bladder expands and contracts along with the charging and discharging of the curing medium.

Currently, vulcanization capsule manufacturers only manually check the appearance quality of the uninflated capsule, and the detection method refers to HG _ T4626-2014. The working state of the capsule in actual production is the expansion state, so the appearance quality detection of the expansion state is very necessary. Because the tire curing bladder is an auxiliary material used in the production process of a tire manufacturer, the existing auxiliary material inspection method only confirms the appearance and the size of an uninflated bladder, and the state after inflation cannot be confirmed. The tire quality is affected and lost due to asymmetric (eccentric) inflation of the vulcanization bladder, and the bladder eccentricity is generally caused by uneven bladder thickness and is a quality defect which is not easy to find. The tire manufacturer generally checks whether the tire is eccentric when the tire is installed, and if the tire is eccentric, the tire is prohibited from being used, and the tire needs to be disassembled and replaced by a new bladder, thereby reducing the production efficiency. Therefore, it is necessary to check the expansion uniformity of the curing bladder before loading (before entering the factory).

Patent document 1CN110702603B discloses a uniformity detection apparatus of a tire curing bladder and a detection method thereof, which detects the uniformity of the tire curing bladder by simulating a pressure test under a real use environment for the tire curing bladder; the detection result can predict the use times; the structure of the tire curing bladder is improved. The patent equipment collects the pressure of the capsule through a pressure sensor and evaluates the uniformity of the capsule. However, the detection method disclosed by the patent is relatively complicated in operation, relatively low in efficiency and not beneficial to large-scale commercial use.

Patent document 2CN211824330U discloses a device for measuring uniformity radial runout of a curing capsule, which prevents the capsule from being clamped into a gap when the capsule is not inflated in time by arranging a clamping disc, thereby preventing the capsule from being broken by clamping, and facilitates the capsule to measure radial runout and take out by arranging an air hole for inputting and outputting air to and from the capsule. The measuring device only carries out single-point contact type detection, the detection of the surface of the whole capsule cannot be realized, and the sensor is easy to damage due to impact.
