The concept of workshop presses (hydraulic presses) is based on Pascal’s theory. The theory states that when pressure is applied on fluids in an enclosed system, the pressure throughout the system always remains the same. In other words, a hydraulic press uses the pressure impacting on the fluids to its advantage by using it as a crushing mechanism.
Workshop presses can also be known as hydraulic presses, or Bramah presses, after the person who invented it (Joseph Bramah).
How does a Hydraulic Press work exactly?
Based on Pascal’s principle, a hydraulic press is similar in functionality to a hydraulic system.
And just like a hydraulic system, it has a cylinder, pistons, the hydraulic pipes, etc. Its functionality is very simple. A hydraulic press works when pressure is applied to a confined fluid (such as oil). The pressure pushes the fluids from a smaller cylinder (slave cylinder), into the larger cylinder (master cylinder). The force applied on the fluids, by the smaller cylinder, results in a larger force when pushed in the master cylinder.
Metal working machines are mostly used for industrial purposes. Specifically where a large pressure is required for compressing metals into thin sheets (sheet metal). A 60 tonne hydraulic press, for example, will use the metal to be worked upon along with the assistance of the press plates to crush or punch the material into a thin sheet.
What can a Hydraulic Press be used for?
The great thing about workshop presses is that they can be adjusted to suit the needs of each individual project. This prolongs the lifespan of the machine, as it reduces the risk of damage. An industrial hydraulic press will often be used to crush or to press metals such as steel plates, aluminum rolls, metallic ores, etc. and for punching, blanking, moulding, clinching and forging. You will regularly see metalworking machines in the automotive and aerospace industries.
Benefits of Workshop Presses
Workshop presses are particularly beneficial as they can compress any material to its maximum. Also, due to their ability to compress a large pressure in a cylinder having a less diameter, they are great for saving space in the facility. Other benefits include:
- Built-in overload protection
- Safe machine to operate
- Small in size
- Low cost to run and maintain
- Quiet in use
- Versatile applications
As you can see, workshop presses offer a multitude of benefits. They are an extremely versatile piece of equipment. Its simple working mechanism make it a firm favourite for many industries.
