[0002] In the tire building process, the radial contraction of the belt drum is a key technical link, which involves the precise construction of the tire structure. The belt drum is a key component of the tire building machine, mainly used to support the tension and shaping of the tire belt layer during the building process.
[0003] The tire forming process is generally completed on a tire forming drum, and has a contracted state and an expanded state. When the forming drum is in an expanded state, the shape of the outer surface of the forming drum is a drum-shaped body close to the shape of the tire, and the tire blank attached to the outer surface of the forming drum is formed into a green tire in this state. When the forming drum is in a contracted state, the radial dimension of the forming drum itself shrinks significantly to facilitate the unloading of the formed green tire from the forming drum. Most of the forming drums used on the market use inertia folding drums, but the inertia folding drum has a large impact force and is easy to cause damage to the articulated pin and the connecting rod mechanism. After folding, the telescopic range is small, making it difficult to unload the tire, and the defective rate of the tire is high. Utility Model Content
