The hydraulic vulcanizer overcomes the inherent weakness of the mechanical vulcanizer and more satisfies the needs of the radial tire, especially the high-grade radial tire vulcanization process.
The hydraulic vulcanizer has a compact frame and a uniform force. Each vulcanization chamber is subjected to a clamping force by a separate frame, and the rigid upper and lower beams ensure that the deformation of the frame is small. At the same time, the frame is symmetrical to the centerline of the mold, and this slight deformation does not cause defects on the vulcanized tire.

1. The linear motion of the upper part of the hydraulic vulcanizer ensures the repeatability and life of the mold. The guide sleeve of the upper mold movement is not affected by the mold clamping force, so the design adopts a small gap to ensure high repeatability.
2. Due to the lack of clamping force, the guide sleeve is made of wear-resistant self-lubricating bushing, which greatly reduces the maintenance workload. Since there is only a linear motion up and down, there is no flipping of the upper mold, which is advantageous for maintaining the accuracy of the active mold and prolonging its service life.
3. The hydraulic vulcanizer adopts the C-type central mechanism. The center rod of the capsule is fixed with the chuck of the manipulator, and the core sleeve is matched to ensure good centering and stability during the setting. The internal pressure medium does not enter the capsule, which saves the medium compared with the A-type vulcanizer. No vacuum system is required.
4. The hydraulic vulcanizing machine adopts a lighter and more flexible tire-loading mechanism, all driven by the cylinder, and the weight is light. The CAD design of the tire-trapper structure is light and flexible, and is suitable for the gripping of the 12′′-18′′ steel ring tire. A positioning sleeve is matched with the center rod of the center mechanism to ensure the concentricity and stability of the setting.
5. The hydraulic system uses hydraulic components, the valve block uses integrated blocks, and the use of superimposed valves and threaded widths reduces the size of the hydraulic station. At the same time, the proportional reversing valve is used as the opening and closing mode control element, which simplifies the system, improves reliability and reduces maintenance.
6. The electric control system uses Siemens S7-300 for vulcanization process control, action process control, pressure PE adjustment, and Siemens' TP-27 touch screen, which can easily realize man-machine dialogue, operation monitoring and fault display.

• The hydraulic system of the vulcanizer consists of two parts: signal control and hydraulic power. The signal control part is used to drive the control valve in the hydraulic power part. The hydraulic power section is represented by a loop diagram to indicate the interrelationship between the different functional components. The hydraulic source contains hydraulic pump, electric motor and hydraulic auxiliary components; the hydraulic control part contains various control valves for controlling the flow, pressure and direction of the working oil; the execution part contains hydraulic cylinders or hydraulic motors, which can be used according to actual requirements. select.
• When analyzing and designing actual tasks, a block diagram is generally used to show the actual operating conditions in the device. The open arrows indicate the signal flow and the solid arrows indicate the energy flow. The sequence of actions in the basic hydraulic circuit—reversal and spring return of the control element (2/2-way reversing valve), extension and retraction of the actuator (double-acting hydraulic cylinder), and opening and closing of the relief valve. For actuators and control elements, the presentation is based on the corresponding loop diagram symbol, which is also prepared for the introduction of the loop diagram symbol.
• All circuits can be numbered sequentially, depending on how the system works. If the first actuator number is 0, the control element identifier associated with it is 1. If the component identifier corresponding to the actuator extension is an even number, the component identifier corresponding to the actuator retraction is an odd number. Not only should the hydraulic circuits be numbered, but the actual equipment should also be numbered in order to detect system failures.
• In practice, another numbering method is to serially number all the components in the hydraulic system. In this case, the component number should be consistent with the number in the component list. This method is particularly suitable for complex hydraulic control systems, each of which corresponds to its system number.
