The application trend of hydraulic press in automobile production includes the following aspects:

-* * Servo Digitization and Intelligentization * *: AC servo motor is more widely used in forging equipment, which speeds up the servo digitalization process of hydraulic press and promotes its further development towards intelligence. For example, the hydraulic press with servo control system can realize more accurate pressure and stroke control.

-* * High-performance and precision * *: In order to meet the requirements of lightweight automobiles and the use of lightweight, high-strength and difficult-to-deform materials with high specific strength, high temperature resistance and high specific modulus, higher requirements are put forward for the internal microstructure and mechanical properties of the workpiece after plastic deformation of the oil press, and accordingly, high performance of the oil press is required to produce parts with extremely high shape and dimensional accuracy.

-* * Customization and individuation * *: With the transformation of manufacturing industry from general type to diversification, individuation and customization, hydraulic press also needs to develop from general type to non-standard equipment suitable for new materials, new processes and products with special shapes and structures with light weight, high strength, corrosion resistance and low plasticity, so as to meet the manufacturing needs of different parts in automobile production.

-* * Networking * *: With the help of global broadband, cloud computer, cloud storage and other technologies, the hydraulic press will realize the functions of local area network production management, automatic control, remote fault diagnosis and maintenance service, and integrate into the environment of network intelligent manufacturing.

-* * Adapting to the manufacturing demand of new energy vehicles * *: With the rapid development of new energy vehicle industry, the application of hydraulic press in this field is increasing. For example, in the metal stamping, forming and assembly of new energy vehicles, servo hydraulic press can manufacture complex parts that meet the design requirements, such as body frame and battery pack shell, with its high precision, high efficiency and stability and reliability. At the same time, the continuous progress of new energy vehicle technology also requires the continuous improvement and optimization of hydraulic press in technical update, high-precision control and production efficiency.

-* * Combination with other processes * *: such as the combination of hydroforming technology and thermoforming technology. Hot forming hydraulic press can be used to produce ultra-high strength automobile parts, meeting the requirements of lightweight and safety of automobiles. Hydroforming technology can be used to manufacture aluminum alloy parts with complex shapes.

-* * High-speed * *: With the rapid development of industry, the demand for high-speed mechanical hydraulic devices and fast forging hydraulic presses is increasing, which requires the moving parts of the hydraulic press to be more reasonable in structure, lighter in weight, and better in frame rigidity. At the same time, it is necessary to achieve the best balance of moving parts and solve the problems such as inertia of high-speed stamping movement, influence of temperature change on accuracy and vibration. However, at present, some technical problems still need to be solved in the application of large and medium-sized fast forging hydraulic press in automobile and aerospace fields, such as large-scale servo motor, high-pressure large-displacement pump, valve and its hydraulic transmission mode and control system.
