A hydraulic press is an important piece of machinery that finds numerous application in industries. It makes use of the hydraulic cylinder to generate compressive force to perform the operation. The machine consists of a plate where the workpiece is placed for sample preparation. It also has a piston that functions as a pump to impart the mechanical force of moderate magnitude to the small area of the sample. For larger force magnitude applications, it is recommended to use pistons of greater diameter. The press operates on the principle of pascal’s law that states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid. The major application of hydraulic press includes molding, blanking, punching, forging, deep drawing, and metal forming operations.
The hydraulic presses are categorized into two types as per the direction of force, vertical and horizontal hydraulic presses. Usually, the presses have a vertical structure except for the few like the one used in extrusion that has a horizontal structure.
A hydraulic press structure can include two/four/eight columns, welding frame, and multi layered steel strip winding frame types. C-frame is mostly observed in medium and small vertical hydraulic presses. It is open on the three sides and is pretty convenient to handle.
