A hydraulic press machine is a press that uses a hydraulic cylinder to generate a compressive force. Instead of a mechanical lever, a hydraulic equivalent is used in a hydraulic press.
How does a Hydraulic Press Machine Work?
The automatic hydraulic press machine is based on Pascal’s Principle, defined as “A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid”. The components of an automatic hydraulic press machine include cylinders, pistons, and hydraulic pipes. The working of the press is quite simple and primitive. The system comprises two cylinders that are filled with fluid. The fluid present inside the two cylinders is usually oil. The fluid (the oil) is filled into the smaller cylinder, which is also known as the slave cylinder.
A piston is inserted into the slave cylinder and pressure is applied. The pressure applied causes the fluid to move through a pipe and into a larger cylinder. The larger cylinder is known as the master cylinder. The pressure exerted on the master cylinder and the piston in the master cylinder pushes the fluid back to the slave cylinder. The force applied to the fluid by the slave cylinder results in a large force, which is experienced by the master cylinder. An industrial automatic hydraulic press machine comes along with what is known as the press plates. With the help of these press plates, the material to be worked on is either punched or crushed into sheets.
