Description

Retractable's complicated structure tire vulcanizer

Technical Field

The invention relates to the technical field of tire processing, in particular to a retractable complex-structure tire vulcanizing device.

Background

As the safety of tires for automobiles is continuously improved, the design of non-pneumatic tires is an indispensable technology in order to meet the safety requirements thereof. The non-pneumatic tire mainly comprises a tread, a rim and a support body. The existing pneumatic tire vulcanizing device leads a green tire to be subjected to uniform pressure through the expansion of a bladder during vulcanization, and finally forms the tire through uniform extrusion and vulcanization. However, when the non-pneumatic tire is vulcanized, the support body is arranged between the bladder and the tread, the support body is in contact with the bladder in a point-to-surface manner, and the support body is in incomplete contact with the tread, so that the force generated by expansion of the bladder is transmitted to the tread through the support body, and the vulcanization cannot be performed due to uneven stress. The existing non-pneumatic tire cannot realize the vulcanization of embedding the support body into the tire tread due to the limitation of a vulcanization device, but adopts the gluing or riveting of the joint of the support body and the tire tread, and the service life of the non-pneumatic tire is shortened due to the fact that the tire is easy to crack at the bonding position due to the heat generated in the running process.

When the existing vulcanizing device is used for vulcanizing a non-pneumatic tire tread, because a supporting body is arranged between a bladder and the tread, if the bladder directly pushes the supporting body to extrude the vulcanized tread, the inner side of the tread is unevenly pressed due to insufficient contact between part of the bladder and the inner side of the tread under the action of the supporting body.

In view of the above problems, a retractable complex-structure tire vulcanizing device is provided.
