Once-forming technology and once-forming device of belt wound type five-drum all-steel radial ply tire

Abstract

The invention discloses a once-forming technology of a belt wound type five-drum all-steel radial ply tire. Parts which need to be bonded are bonded into a tire cylinder A on a tire bonding drum, the tire cylinder A is rotated on a forming drum II to wait, a belt layer composite part B is manufactured on a station I of the belt bonding drum, the belt of the belt layer composite part B is wounded by steel wires to obtain a belt layer composite part C, the belt layer composite part C is bonded with a tire surface to form a tire surface and belt layer composite part D, the tire surface and belt layer composite part D is combined with the tire cylinder A to form a tire blank E, and the tire blank E is formed to obtain a finished product. The invention adopts a wound type to manufacture the belt layer, avoids a lapping phenomenon of a joint, can satisfy the high-performance requirements of dynamic balance, uniformity, and the like of the all-steel radial ply tire, and the five-drum forming device is used for satisfying the technical requirements of the technology and increases forming production efficiency.

Description

technical field [0001] The invention relates to a tire processing method and device, in particular to a belt-wound five-drum all-steel radial tire one-shot molding process and device. Background technique [0002] The current one-shot forming process of all-steel radial tires generally involves laminating sidewall inner liner composites, slit reinforcing layers, slit coverings, carcass cords, steel rings and other components on the carcass laminating drum, and The carcass transfer ring transfers the carcass compound to the building drum, and then pastes the shoulder pad glue on the building drum, and performs 1# belt layer, 2# belt layer, and 3# belt layer on the belt bonding drum. Lamination of plies, zero degrees, treads and other components, use the tread transfer ring to transfer the tread and belt layer composites from the belt layer lamination drum to the forming drum and combine with the carcass cylinder to form a blank, which is passed through the inflation , shapin...

AI Technical Summary

Problems solved by technology

Today, the requirements for dynamic balance and uniformity of tires are getting higher and higher, and the lapping of traditional zero-degree belt layers is bound to seriously affect the dynamic balance and uniformity of tires. Therefore, it is necessary to create a new tire suitable for high-performance tires. Forming machine technology and matching forming machines to meet the production of tires
