The invention belongs to the field of a vulcanizing device and a vulcanizing process, and particularly relates to a process and a device for vulcanizing and forming a rubber tire by blowing nitrogen and electrically heating.
Background
At present, the vulcanization molding process of rubber tires at home and abroad mainly utilizes the combination of water vapor and nitrogen to realize vulcanization molding. The preparation steam is mainly generated by a boiler burning a large amount of coal and then is transmitted to vulcanization molding equipment through a pipeline, so that a large amount of waste gas such as CO2 and S02 is discharged to pollute air in the production and transmission process, and the pipeline of the steam has large loss in long-term use; in the tire vulcanization process, steam and nitrogen are mixed, so that nitrogen at high temperature and high pressure is impure, the problem of over-oxidation aging of the bladder and the tire also exists, and the nitrogen contains a large amount of water, so that the repeated utilization rate of the nitrogen is low, and the production cost is relatively increased, so that the vulcanization process and the device are not environment-friendly and have high production cost. There are also some enterprises that use an electrically heated rubber tire vulcanization molding process instead of steam and nitrogen to heat a rubber tire, which results in another disadvantage: the upper heating plate, the lower heating plate and the die sleeve are heated unevenly, the temperature close to the heating coil is high, and the temperature far away from the heating coil is low; the forming inner bag of the upper ring central mechanism is made of a metal sheet with high thermal conductivity, extrusion forming force is applied to the inner wall of a tire blank through a mechanical mechanism, the inner wall of the rubber tire cannot be uniformly stressed, meanwhile, the metal forming inner bag is not universal, and the metal forming inner bag with corresponding specification and shape is required to be matched when rubber tires with different specifications and models are vulcanized, so that the industrial batch production cost is increased; the hot nitrogen vulcanized rubber tire forming process is adopted, and the hot nitrogen cannot meet the requirements of the rubber tire vulcanization forming process because the specific heat capacity of nitrogen is low and a large amount of heat energy is required in unit time of rubber tire vulcanization forming. Therefore, it is necessary for those skilled in the art to invent an environment-friendly and efficient rubber tire vulcanization molding device and process thereof.
The prior patent entitled "method and apparatus for hot nitrogen curing tires" discloses a method for hot nitrogen curing tires, which includes a tire curing process in which heated, pressurized pure nitrogen gas is directly charged into a bladder in a tire mold of a vulcanizer or a vulcanizing tank during tire curing. The invention avoids the damage to the inner structure of the tire caused by sudden rise and drop of pressure and temperature in the tire vulcanization process, thereby improving the quality of the vulcanized tire, having good continuity of the pressure and temperature of the tire vulcanization, prolonging the service life of the bladder, improving the labor productivity, reducing the production cost, being beneficial to environmental protection and having wide application range. However, the method still adopts the process of vulcanizing the inner wall of the rubber tire by using hot nitrogen, and the method is not practical in vulcanization molding of the rubber tire industrially, and has low vulcanization efficiency and poor vulcanization effect.
