Description

Rubber tyre shaping rolling press device Technical Field The utility model relates to the technical field of rubber tire molding, in particular to a rubber tire molding rolling device. Background Tires are ground-engaging rolling annular elastic rubber products mounted on various vehicles or machines, are usually mounted on metal rims, can support the vehicle body, cushion external impacts, realize contact with the road surface and ensure running performance of the vehicle, are often used under complex and severe conditions, and are subjected to various deformation, load, force and high and low temperature effects during running, so that the tires must have high bearing performance, traction performance and cushioning performance, and at the same time must have high wear resistance and flex resistance, and low rolling resistance and heat resistance. In the production process of the tire, the tire blank is required to be sleeved on the forming drum, the rubber pad is paved on the forming drum to roll, the tire forming is realized, the working procedures such as shaping, tread pressing, turn-up and sidewall pressing are required to be carried out in the rolling forming process of the tire, however, the existing tire rolling forming equipment only completes the working procedures on one forming drum, and the processing efficiency of tire forming is lower due to longer forming time of a single group of tires. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides a rubber tire forming rolling device.
