Working Principle of Hydraulic Forging Press

Hydraulic forging press is a kind of forging equipment that uses hydraulic system as the core power source. Its working principle and process are as follows:

When starting the equipment, the motor starts working and drives the oil pump to draw liquid medium (usually oil) from the oil tank. These oils are then pumped into high-pressure oil pipes, creating powerful hydraulic power. The high-pressure oil pipe is closely connected with the carefully designed quick switching valve and hydraulic cylinder to ensure that the oil can be delivered accurately.

When forging is required, the control system will accurately adjust the quick-switch valve so that high-pressure oil quickly enters the hydraulic cylinder. Under the influence of oil, the piston in the hydraulic cylinder will push forward, thereby exerting the required forging pressure on the forging. When the hydraulic cylinder is filled with oil and reaches a predetermined pressure, the quick switch valve will quickly close to keep the pressure in the hydraulic cylinder stable.

After completing the forging process, the control system opens the oil drain valve of the hydraulic cylinder. At this time, the oil will flow back from the hydraulic cylinder to the tank, causing the pressure in the hydraulic cylinder to decrease. As the pressure is released, the hydraulic cylinder retracts rearward, allowing the forging to be easily removed from the die. After this process is completed, the hydraulic forging press is ready for the next forging task.

In this way, the hydraulic forging press achieves efficient and precise forging operations, providing strong power support for industrial production.
