Forming method and winding equipment for improving bearing capacity of all-wire radial tire ring part

Abstract

The invention belongs to the technical field of tire forming and manufacturing, and particularly relates to a forming method and winding equipment for improving the bearing capacity of an all-wire radial tire ring part. The forming method comprises tire body drum side operation, belted layer drum side operation and forming drum side operation, wherein the forming drum side operation comprises ring locking, shaping, tire crown pressing, tire bead pressing, zero-degree reinforcing ring winding, tire side turn-up, tire side pressing and tire unloading. The zero-degree reinforcing ring winding comprises the steps of monofilament unwinding, material storage, glue coating, air drying, monofilament winding and cutting. The winding equipment comprises an unwinding mechanism, a storage mechanism, a glue coating device, an air drying device and a winding machine head. According to the technical scheme, the rigidity of the product ring part can be effectively improved, the shear strain of the ring part during tire use is reduced, and therefore the bearing capacity of the ring part is reinforced and improved.

Description

technical field [0001] The invention belongs to the technical field of tire molding and manufacturing, and in particular relates to a molding method and winding equipment for improving the bearing capacity of an all-steel radial tire bead. Background technique [0002] According to the tire sales market feedback, the current market complaints of all-steel radial tires for heavy trucks are mainly reflected in ring cracks, ring voids, and ring bursts. Similar complaints have appeared in many models and specifications in the heavy-duty tire market. After analysis, there are ring cracks, rings, etc. The empty space and lap burst are mainly related to the service conditions and tire structure of the tire. In order to meet the market demand, it is necessary to improve the load-carrying performance of the heavy-duty tire product ring, improve the durability of the tire ring, and ensure driving safety. [0003] In the current tire manufacturing process, the steel wire reinforcement ...

AI Technical Summary

Problems solved by technology

[0003] In the current tire manufacturing process, the steel wire reinforcement layer and the nylon reinforcement layer are laminated layer by layer to increase the strength of the ring part of the heavy-duty product. However, the strength of the ring part increased by this method is very limited, and it cannot effectively improve the heavy-duty tire. There are problems such as ring voids and ring cracks in the market all the year round, and this method will greatly increase the complexity of the production process, increase the difficulty of production process control, waste molding efficiency, and increase risks such as air bubbles in the finished ring
