Diagram of a Hydraulic Press
A typical hydraulic press comprises a hydraulic cylinder, a piston, a ram, a worktable, and a control system. The hydraulic cylinder contains hydraulic fluid, which is pressurized by a pump to move the piston. The piston’s movement is transferred to the ram, which applies force to the workpiece placed on the worktable. The control system regulates the pressure and speed of the ram, allowing for precise control over the pressing operation.
Safety features such as emergency stops and pressure relief valves are integrated into the design to enhance safety.
