Problems solved by technology

The waiting time for such operations as inflation, deflation, and push plate compaction is long, and the compaction of the capsule after inflation and deformation by the push plate is an indirect elastic compaction, so the compaction quality cannot be guaranteed to be uniform, so It will have a certain adverse effect on the internal quality of tire blank molding

Abstract

The present invention relates to an automatic back contact rolling mechanical forming drum, including coupling flange, back contact rolling arm elastic rubber ring, drive back contact rolling piston component and cylinder body sleeve the the front end of which is equipped with sector block cylinder body, drive sector block piston group, sector block connecting bar group, fastening tire body sector block group and sector guide disk. The rear end of the described piston component is symmetrically equipped with back contact rolling arm component, back contact rolling wheel group and free guide bearing group. The rear end of the described cylinder body sleeve is equipped with dished pushing disk, and a slide-fit cylinder body rear end cover is mounted on the cylinder body sleeve, and the rear portion of the described back contact rolling arm component is connected at the rear end cover place of the cylinder body.

Description

(1) Technical field: [0001] The invention relates to a rubber tire machine, in particular to an automatic turn-up and rolling mechanical forming drum used on a single-stage forming machine of special equipment for producing radial truck tires. (two) background technology: [0002] Most of the special carcass building drums used in the existing radial truck tire one-step building machine are inflatable capsule turn-up forming drums. During the carcass forming process, compressed air needs to be filled into the capsule to make the capsule expand. It is also necessary to rely on a separate metal structure push plate to compress the deformation of the capsule to complete the turn-up and compaction of the sidewall of the tire. After this operation is completed, the gas in the capsule needs to be discharged to restore the capsule to its original state. In order to carry out the operation of the next molding operation. The waiting time for such operations as inflation, deflation, ...
