4. Functional complexity.

5. Low noise..

6. High energy-saving efficiency.

7. What you see is what you get.

Intelligent hydraulic presses have a wider range of applications than traditional hydraulic presses, with high added value. They can be used in precision forming processes such as metal sheet stamping, isothermal forging, powder pressing, rubber vulcanization, fiberboard hot pressing, straightening, pressing, injection molding, etc.

The main key technologies for the development of intelligent hydraulic presses are as follows:

1. Research and development of main oil pump for hydraulic press directly driven by servo motor.

2.High power AC servo motor and drive control system.

3. Specialized control system. Due to the fact that most existing hydraulic presses are controlled by PLC, while intelligent hydraulic presses use hydraulic and speed closed-loop program control, which requires a large amount of computation, ordinary ones are difficult to meet the needs of process flexibility. Therefore, it is necessary to develop a dedicated control system using industrial PC.

4. Energy recovery and energy management system. In order to minimize energy loss as much as possible, it is necessary to recover and reuse the potential energy generated by the self weight of the slider and the energy generated by the pressure relief of the oil cylinder.

5. Optimization of Forming Process Based on Intelligent Hydraulic Press. The production process of parts varies depending on their materials and shapes. The combination of intelligent hydraulic press and various forming process optimizations, understanding the optimal process path, is necessary to fully demonstrate its superiority.

6. Optimization design of intelligent hydraulic press body. Compared with traditional hydraulic presses, intelligent hydraulic presses have more factors to consider in their body design due to their advantages such as energy saving, noise reduction, and functional complexity. These factors mainly include various possible thermal processing effects, extreme working conditions, operating frequency, and complexity of parts.

7. Software serving the design and manufacturing of intelligent hydraulic presses.
