What is the difference between a pneumatic punching machine and a hydraulic machine?

We all know that punching machines can be divided into several types of punching machines according to different classifications. Today, we will talk about the difference between pneumatic punching machine and hydraulic punching machine.

First, from the action product distinction

1.pneumatic punch press action product is the cylinder, the cylinder uses compressed gas as a power source, so it can also be called pneumatic pressurizer or pneumatic press. Pneumatic punch press uses the high pressure gas produced by the compressor, the compressed gas is delivered to the solenoid valve through the pipeline, and the foot switch is used to control the action of the solenoid valve to control the work and return of the cylinder, so as to realize the tasks of punching and dropping materials. Because the pneumatic system is characterized by controllability and fast response speed, the pneumatic punch press is very suitable for small and medium-sized punching tasks.

2. hydraulic press action products are hydraulic cylinders (hydraulic cylinders), hydraulic cylinders use hydraulic oil as a power source, through the hydraulic system to transfer and control the punching pressure. Hydraulic press is usually called hydraulic press or hydraulic press. Hydraulic cylinders can provide greater pressure than cylinders, suitable for operations requiring higher punching pressure.

Second, from the size of the force to distinguish

1.pneumatic punch press force is smaller, mainly suitable for light or small stamping parts processing. Although the cylinder of the pneumatic press can adjust the pressure, but because of its power source is gas, the force is relatively low, suitable for dealing with thinner materials or punching pressure requirements of lower work.

2. In contrast, the hydraulic press has a much higher output. Hydraulic press cylinders can provide a strong pressure output, suitable for high-power stamping tasks, can handle thicker metal materials, especially suitable for workpieces suitable for high-intensity, high-precision stamping operations.

Third, from the action speed to distinguish

1.pneumatic punch press action speed is faster. The cylinder of the pneumatic press is driven by compressed air, and the flow speed of the gas is faster than that of the liquid, so the pneumatic press can complete the stamping operation in a shorter period of time. This makes the pneumatic press perform well in high-frequency and high-speed production lines and can meet the demand for higher output.

2.Hydraulic presses are relatively slow. Hydraulic presses use hydraulic fluid, and the fluid flows relatively slowly. Hydraulic systems usually require longer acceleration and deceleration processes in order to provide greater force, so hydraulic presses are suitable for operations that require finer control and high-precision control, and are usually used for low-speed but high-load stamping tasks.

Fourth, from the stability of the distinction

1.pneumatic presses are less stable, because the unstable pressure of the air source may lead to fluctuations in the output punching force. The pneumatic system is affected by the supply of compressed air and air pressure, when the air source pressure is unstable, there may be large fluctuations, which in turn affects the stamping quality and stability.

2.in contrast, the hydraulic press is more stable. The pressure of hydraulic oil is very stable, so the hydraulic system can provide uniform punching pressure, thus ensuring the stability and precision of the whole punching process. Hydraulic press is suitable for applications requiring high precision.

Fifth, from the price distinction

1.pneumatic press is relatively cheaper, because its structure is relatively simple, the use of compressed gas, low operating costs, and maintenance is very simple.

2.hydraulic press is more expensive, mainly because of the complexity of the hydraulic system, involving hydraulic oil, pumps, tanks, valves and other components. These components require regular maintenance, and the maintenance of the hydraulic system is more complex, especially in the event of hydraulic oil leakage or pump failure, the repair is more difficult and maintenance costs are higher.
