The hydraulic press is an equipment that uses hydraulic cylinders to generate a compressive force. It allows the transmission of a multiplied force and displacement, to deform or crush an object for example.
How does a hydraulic press work?
The operation of the hydraulic press is based on Pascal’s Law and is thus similar to the operation of a hydraulic system.
Hydraulic presses are made up of two interconnected cylinders, with one being larger than the other. The larger cylinder is referred to as the Ram, while the smaller one is referred to as the Plunger. Each cylinder is filled with pressurized hydraulic fluid.
The hydraulic press operates by applying a small amount of force onto the Plunger, which pushes the fluid below. This pressure is then spread evenly, raising the Ram. The pressure between the Plunger and the Ram then works to crush the item placed between them.
Unlike mechanical presses, hydraulic presses offer the advantage of precise force control. As they have no wearing parts, they also tend to require much less adjustment over time.
Why use a hydraulic press?
While the hydraulic press is often found in automotive or precision engineering workshops, it is also used for many other industrial applications. From the shaping of machine components to crushing waste and refuse, hydraulic presses are an essential part of modern industrial operations.
Depending on their use, there are different types of hydraulic presses, such as:
-
Straightening and bending presses
-
Compression presses for thermosetting or thermoplastic materials
-
Injection presses for aluminum or plastics
-
Stamping presses
-
Forging presses
-
Calibration presses
-
Die casting presses
-
Cold forming presses
How to choose a hydraulic press?
The tonnage of hydraulic presses typically ranges from 5 to 100 tons. It should be determined according to the nature of the material being processed, its thickness, and the type of operations required.
It is also necessary to know the dimensions of the parts that will be handled on the press. This helps to define the sizing of the work table and the height of the opening.
