Hydropneumatic presses are initially driven by compressed air only, and then they activate the hydraulic power stroke automatically. These presses combine the benefits of pneumatic systems and pneumatic hydraulic presses, taking the pneumatically driven fast stroke, which approaches the workpiece with low force, and combining it with the automatically-activated hydraulic power stroke that engages when it encounters resistance.
As a result of this combination, the applied energy is used to the most economic effect. Hydropneumatic presses do not need a hydraulic power pack, and they can also be used where space is at a premium.
Advantages of Hydropneumatic Presses
There are many benefits of using hydropneumatic presses, including:
These presses use compressed air as their primary source of power, and it results in the inexpensive and reliable implementation of piping systems and components. This completely eliminates the need for expensive hydraulic components such as hydraulic oil.
The use of compressed air leads to a quicker approach and retraction which results in a faster response.
Hydropneumatic presses are lightweight and compact, which makes it easy to mount them on a table. Additionally, there is no need to install a hydraulic power pack, which can save you a lot of floor space.
These presses are serious energy savers. They can save up to 50% in energy inputs over fully hydraulic and pneumatic systems, and they can save more than 70% in terms of cost compared to traditional hydraulic systems.
Hydraulic presses are relatively easy to use. This is because of their simple sealing components and pneumatic elements.
Many people prefer to use hydropneumatic presses over hydraulic presses for a variety of applications, like bending, riveting, forming, marking, clamping, punching, and straightening. And that's because the presses have several advantages over different types of equivalent hydraulic systems.
Machine tool production is concentrated in roughly 10 countries around the world, and it's no secret why hydropneumatic presses are an important part of that industry. If you have more questions about these phenomenal pieces of equipment, don't hesitate to contact our experts at AIM Joraco today.
