[0027] This embodiment describes a rubber support anti-steel plate deflection device. In use, according to the size requirements of the steel plate and rubber, the required number of positioning frames are installed on the corresponding mounting holes, ensuring that the narrow contact surface of each positioning frame corresponds to the outer edge of the rubber support. Then, the steel plate and rubber are inserted, and the upper pressure plate is rotated above the positioning frames. Next, the crossbar is rotated until it is between the upper pressure plate and the limiting surface of the U-shaped limiting bracket. After confirming that all components are without deviation, the hydraulic station is activated. The hydraulic station can adjust the output pressure according to different needs. The hydraulic station drives the hydraulic cylinder, and the working end of the hydraulic cylinder extends upwards, acting on the steel plate and rubber. The steel plate and rubber move upwards until they contact the upper pressure plate, which in turn contacts the crossbar, which in turn contacts the limiting surface. Then, the working end of the hydraulic cylinder pre-presses the steel plate and rubber, causing them to adhere together. The positioning frame ensures that the steel plate and rubber move upwards along the narrow contact surface, preventing any deviation of the steel plate during the process. After holding the pressure for the set time, the hydraulic cylinder moves downwards to its initial position, rotates the crossbar to disengage from the U-shaped limiting bracket, removes the upper pressure plate, and then removes the rubber support with the steel plate and rubber adhered together. The process then awaits the next pre-pressing process. The removed rubber support can then be transferred to the vulcanization process for vulcanization.
