Problems solved by technology

The inflation, deflation, push plate compaction and other operations need to wait for a long time, and the compaction of the capsule after inflation is pressed and deformed by the push plate is an indirect elastic compaction, so the compaction quality cannot be guaranteed to be uniform. The inherent quality of embryo forming will bring certain adverse effects

Abstract

A mechanical shaping drum including a carcass fastening mechanism features that the said mechanism has a cylinder-piston driven connecting rod unit which is composed of cylinder, piston, connecting rod of piston, sectorial block, guide spline and sealing plate. Its advantages are firmly fixing the type blank to the mechanical shaping drum, high antiwear performance and durability of the mechanical shaping drumo and low cost of production.

Description

(1) Technical field: [0001] The invention relates to a rubber tire machine, in particular to a mechanical forming drum used for a special component for carcass forming in a one-shot forming machine of a special equipment for producing radial truck tires. (two) background technology: [0002] The existing radial truck tire one-step building machine is equipped with a special carcass building drum that is an inflatable capsule building drum. During the final forming process of the carcass, it needs to fill the capsule with compressed air to expand the capsule. Relying on a single metal push plate to compress the bladder to deform, to complete the compaction of the sidewall and shoulder of the tire for final molding. Proceed to the operation of the next molding operation. The inflation, deflation, push plate compaction and other operations need to wait for a long time, and the compaction of the capsule after inflation is pressed and deformed by the push plate is an indirect el...
