Compared with mechanical presses, what are the advantages of hydraulic presses?

Working principle of hydraulic presses: hydraulic system is used as power source, and the pressure of liquid is used to drive the piston movement to realize the processing process. Mechanical presses realize processing through mechanical transmission, and their power source comes from motors or engines. The working principle of hydraulic presses is simpler, the noise is low during processing, and it is more energy-saving and environmentally friendly.

 

The working speed and efficiency of hydraulic presses are relatively slow, but their processing accuracy and efficiency are higher. Hydraulic presses can be adjusted according to processing needs to make the processing more refined. Mechanical presses work faster, but their efficiency and processing accuracy are relatively low.

 

The hydraulic system of hydraulic presses can automatically adjust the movement speed and strength of hydraulic cylinders, making the processing process smoother and the processing quality more stable. Mechanical presses are limited by mechanical structure, and vibration and noise are prone to occur during processing, and the processing quality cannot be guaranteed.

 

Hydraulic presses are suitable for processing workpieces with high requirements for precision and stability, such as automotive parts, aerospace parts, etc. Mechanical presses are suitable for processing workpieces with high requirements for speed and efficiency, such as metal sheets, pipes, etc.

 

Compared with mechanical transmission and electrical transmission, hydraulic transmission has the following advantages:

1. Various components of hydraulic transmission can be arranged conveniently and flexibly according to needs.

2. Light weight, small size, small motion inertia and fast response speed.

3. Convenient operation and control, and can achieve a wide range of stepless speed regulation (speed regulation range up to 2000:1).

4. Overload protection can be automatically realized.

5. Mineral oil is generally used as the working medium, the relative motion surface can be self-lubricated, and the service life is long.

6. It is easy to achieve linear motion.

7. It is easy to realize the automation of the machine. When electro-hydraulic combined control is adopted, not only a higher degree of automatic control process can be achieved, but also remote control can be achieved.

8. Under the condition of outputting the same power, the volume and weight can be reduced a lot, the layout and installation have great flexibility, and can form a complex system that is difficult to form by other methods.

9. The transmission movement is uniform and stable, and it is easy to achieve rapid start, braking and frequent reversing, and a wide range of stepless speed change can be achieved during operation.

10. The operation control is convenient and labor-saving, and it is easy to achieve automatic control and overload protection. Hydraulic components are easy to achieve serialization, standardization, and generalization.

 

In summary, hydraulic presses have more advantages than mechanical presses. The working principle of hydraulic presses is simpler, the efficiency is higher, the stability is better, and the application range is wider. When choosing processing equipment, it should be selected according to specific needs.
