Technical Field
The invention belongs to the technical field of tire vulcanization, and particularly relates to a method and equipment for directly pressing and vulcanizing an open-type magnetic circuit induction heating tire.
Background
Vulcanization, as the final step in the tire manufacturing process, has a very important impact on tire performance. In the traditional vulcanization process of the tire, the green tire is heated by introducing superheated water into the bladder. Because of its low efficiency, the method is improved to introduce high temperature steam and high pressure nitrogen gas into the capsule to heat the green tire, but the method still has the following disadvantages: 1. the required vulcanization time is different due to different thicknesses of all parts of the tire, and the phenomenon of uneven vulcanization degree often occurs in the traditional vulcanization process, namely, the thicker tire shoulder part is not completely vulcanized, and the thinner tire tread part is already in an over-vulcanization state; 2. the curing bladder is made of a rubber material, cannot obtain a stable shape due to its elasticity after being expanded and compressed, and is also cured along with the green tire, thereby deteriorating the quality of tire curing. In the subsequent use process of the tire, in order to meet the dynamic balance condition, a balancing weight needs to be added, so that the energy loss is increased; 3. during the vulcanization process, the bladder needs to be frequently inflated and deflated, so that the service life of the bladder is uncertain and the bladder may need to be frequently replaced; 4. the temperature and the pressure are coupled in the vulcanization process, and the temperature or the pressure cannot be independently adjusted, so that the vulcanization process condition is difficult to control; 5. high-temperature steam is condensed into liquid water above the capsule and accumulated below the capsule due to small density of the high-temperature steam, so that temperature difference exists between the top and the bottom of the capsule, the capsule cannot uniformly transfer heat in the axial direction, and the quality of a final product is influenced; 6. the heat transfer medium has a low thermal conductivity and loses much energy during the heat transfer from the heat transfer medium to the tire, resulting in increased production costs. In the subsequently produced tire electromagnetic induction heating technology, an independent electromagnetic induction heating module needs to be arranged on each tile block, and the inner mold driving mechanism enables the axial distance of the central mechanism to be too large, so that the structure and the control are complex.
