What is a Hydraulic Press?

A hydraulic press is a mechanical device that uses the static pressure of a liquid, as defined by Pascal‘s principle, to shape, deform, and configure various types of metals, plastics, rubber, and wood. The mechanism of a hydraulic press consists of a mainframe, power system, and controls.

Pascal‘s principle states that when pressure is applied to a confined liquid, a pressure change occurs in the liquid. For a hydraulic press, the pressure in a liquid is applied by a piston that works like a pump to create mechanical force.

Chapter Two: How a Hydraulic Press Machine Works

The process of a hydraulic press begins when a hydraulic fluid is forced into a double acting piston. The compressive force inside the small hydraulic cylinder pushes the fluid into a larger cylinder where more force and pressure are applied. The movement of the larger piston forces the fluid back into the smaller piston cylinder.

Cylinders

The number of cylinders in a single column hydraulic press varies according to its design. The function of the cylinders is to generate the compressive force that drives the anvil and die. In a two cylinder design, the diameter of the cylinder that carries the ram is larger, while the diameter of the second cylinder that carries the plunger is smaller. Cylinders are metal pipes with two ports for the input and output of hydraulic fluid.

The cylinders are connected by a pipe containing hydraulic fluid. When the plunger in the small cylinder applies pressure to the hydraulic fluid through a downward action, the created pressure is applied to the ram. The action in the smaller cylinder by the downward movement of the plunger is that of a mechanical actuator used to produce unidirectional force by a unidirectional stroke.With an H frame (two column) hydraulic press, the frame, press cylinder, pump, and bolster are in the shape of an "H." The uses for H frame hydraulic presses machine include work in repair shops, maintenance buildings, and production assembly lines. They have a hand pump for low volume applications or air and electrical pumps where consistent operation is required. The amount of available force in an H frame depends on the size of its cylinder.

Four Column Hydraulic Press

Four column hydraulic presses can apply substantial force to any size work piece. They can have a single or two cylinder design depending on the requirements of the manufacturing process. Four column presses have a central control system with semi-automatic cycling and adjustable pressure and compression speed. The punching and working pressure are adjusted in accordance with the needs of the stroke range.

Horizontal Hydraulic Press

There are operations where it is difficult to shape a component or part using a conventional vertical press because the part is too long or short to load vertically. Those types of workpieces are shaped by a horizontal press where pressure is applied horizontally.

With a horizontal press, there are two platens with one being fixed while the other is movable. Pressure is applied horizontally between the platens. This type of press has a protective mechanism on the hydraulic system to avoid overload, and it can have different tools attached.

Hydraulic Wheel Press

A horizontal wheel hydraulic press is used for mounting and unmounting wheels, bearings, gears, and sheaves onto and off of shafts, axles, rolls, or armatures. They are used for the correction of shaft parts and pressing of shaft sleeve parts. A wide range of industries use hydraulic horizontal wheel presses as part of their production process. Examples include the automotive, motor, electronics, mining, and home appliance industries where precision press mounting is necessary.

Straightening Hydraulic Press

When large, long shafts from oil rigs, cars, trucks, and aircraft need to be straightened, the ideal method is a hydraulic straightening press that slowly controls the straightening process, resulting in accurate and fully functional parts. Hydraulic straightening presses can be used to straighten shafts, plates, and large weldments.
