[0002] With the rapid development of the automobile industry, the automation degree of the tire industry is getting higher and higher. The known relatively advanced vulcanizing machine, such as the patent number: 200920056320.3, the patent name is: high-precision frame hydraulic tire vulcanizing machine, this device realizes Low running noise, few failures, high start-up rate, low energy consumption, long mold life, and high production efficiency. The raw tire is not vulcanized, and some plastic flow will occur, resulting in a change in shape. Under the pressure of its own weight, the lower sidewall is stressed, so the deformation of the lower edge of the raw tire is particularly serious. If such a green tire is put into the vulcanization mold Vulcanization will produce uneven vulcanization, resulting in poor tire quality and burying hidden dangers for tire quality

The lifting mechanism adopts a general linear guide structure, and there is often an offset during the lifting process. The low precision will affect the gripping of the tire and the service life of the device; Stability; there are two main methods for the arm buffer mechanism: one is to install a buffer on the arm of the manipulator, and use a bumper to buffer at the limit position of the swing. Because the stroke of the cylinder is too long, the arm has a little swing. The force is uneven, causing a certain impact. Another way is to install the buffer on the piston rod that is turned in and out of the cylinder, and move with the piston rod. Since the piston rod is relatively thin, the force is small, and it is swinging When the tire gripper reaches the limit position, the mass and inertia are large, which causes a certain swing deformation of the piston rod, resulting in unstable cushioning work and poor cushioning effect, resulting in severe vibration of the manipulator at the stop position

For tires that have just been vulcanized and need to be inflated, cooled and shaped, a two-station four-point post-inflated, cooled and shaped device with a high degree of automation, compact process, high positioning accuracy, and high efficiency is mostly used. Most of these devices use a turning mechanism for turning over , so as to improve labor efficiency. However, most of the current turning mechanisms are driven by motors and driven by sprockets and chains. However, in the process of use, the tension of the chains often varies, resulting in unstable turning and positioning. firm situation arises
