The Solution to Loss of Load of Two-Column Hydraulic Press

The principle of the loss of load of the two-column hydraulic press is that due to the excessive energy stored in the hydraulic cylinder, the loss of load will occur once it is released. The following introduces the reasons and solutions for the loss of load of the two-column hydraulic press:

1. Releasing energy from the excess doorway: When the two-column hydraulic press suddenly starts to lose the load, it bypasses the local low-pressure liquid in the cylinder and releases it to increase the released energy.

2. Discharge energy for shock absorption: set a buffer pad at the lower part of the two-column hydraulic press. When the energy is almost used up, the buffer pad that is partially contacted when cut off is stopped, and the local energy is eliminated on the buffer pad.

3. Increase the storage of liquid elastic energy: the pad can be thickened between the task table and the lower part to make the task stroke of the static beam move upward, thereby increasing the height of the liquid column of the two-column hydraulic machine cylinder.

4. A movable pad is added between the cylinder piston and the static beam, that is, when the idle stroke of the two-column hydraulic press descends, the piston and the beam descend together. After contacting the workpiece, the piston returns to restore before pressurizing, and the auxiliary hydraulic pressure is at this time. The measure of the cylinder presses the movable pad between the piston and the stationary beam.
