Pressing method and pressing device

A pressing method, comprising:

• providing an object to be pressed;
• providing a lower pressing die, wherein the lower pressing die is provided with a support seat for holding the object to be pressed;
• providing an upper pressing die, wherein the upper pressing die can be driven to move up and down relative to the lower pressing die, the upper pressing die is provided with a driving mechanism and a pressing block mechanism that can be driven by the driving mechanism, and the driving mechanism comprises a main body having a chamber that can accommodate a fluid, a piston that can change a pressure of the fluid in the chamber via displacement, and a plurality of plungers that can be simultaneously driven by the pressure of the fluid in the chamber to move up and down;
• and
• when the object to be pressed is pressed, the pressing block mechanism of the upper pressing die presses an upper surface of the object to be pressed, such that the pressing block mechanism applies an upward pressure to the plungers, and the driving mechanism then uses the piston to act on the fluid in the chamber to indirectly apply a reverse downward pressure to the plungers through the fluid to make the plungers press the object to be pressed.
