HYDROPNEUMATIC CYLINDERS

As fast as a pneumatic cylinder and as strong as a hydraulic one

How they Work

Pneumo-hydraulic cylinders integrate two components in a single actuator: a pneumatic cylinder and an air/oil pressure intensifier.
The pneumatic cylinder is located in the lower part of the unit and allows for rapid approach to the workpiece.
The air/oil intensifier is located in the upper part of the unit and allows the pressing of the piece with high force (up to ten times greater than the force that would be obtained with an air cylinder of the same bore).
Pneumo-hydraulic cylinders can replace hydraulic cylinders, eliminating the need for a dedicated hydraulic power unit.

High Flexibility of Applications

Bending
Drawing
Keying
Assembly
Clinching
Trimming
Chamfering
Marking
Straightening
Riveting
Pressing
Cutting
Compressing


With 2 models and 9 sizes (thrust force from 50 kN to 419 kN) the pneumohydraulic power units of the AP and AX series offer high productivity at low costs.

They use compressed air as the only power source.
The closing of the mold is completely pneumatic, fast, efficient and inexpensive.
Once in contact with the piece, the ingenious air-oil multiplier system develops the force necessary for the actual pressing.

Pressings, fittings, deformations, assemblies.
Operations that the cylinder performs easily, efficiently, combining the best of pneumatic and hydraulic technologies.

 

The Advantages

RELIABLE
High resistance steel structure, high quality hydraulic and mechanical seals.
These cylinders are built to last.

PRODUCTIVE
With pneumatically controlled approach and return and hydraulic pressing stroke, they guarantee reduced cycle times for unrivaled yield.

REDUCED CONSUMPTION
The pneumatic/hydraulic separation limits consumption to the pressing phase only, only when needed.

VERSATILE
With 2 models and 9 sizes (with thrust force from 5 kN to 419 kN) it is easy to find a cylinder to fit your application.

The AP Series


The hydropneumatic cylinders of the AP series have an linear structure.

The pneumatic part for approaching the piece and the hydraulic part for executing the pressing stroke are in fact placed on the same axis.

Simple and economical, it is the right choice when there are no particular problems of space.

The AX Series


The hydropneumatic cylinders of the AX series present the same technical and functional concept as the AP series.
Thanks to their compact size, they can be used when small dimensions are needed.

Their peculiar shape allows longer approach and working strokes, compared to the AP series.

The AX version can also be equipped with the BDC and TDC mechanical adjustment device (code XR).

The UP Series


The UP power units only carry out the working stroke, when the approach stroke is not necessary. They consist of a hydraulic multiplier that allows immediate use of force.

The characteristics of use are:

  • Short work stroke
  • Speed of execution
  • Simplicity of installation
  • Economical operation
  • Alternative for hydraulic cylinders

X

Headers

Made of high resistance phosphated steel.

The open groove housing of all the gaskets extends the life of the seals and facilitates maintenance operations.

X

High Pressure Chamber Connection

By connecting a pressure transducer it is possible to detect the pressure / force of the working stroke.

X

Loading Duct

It allows you to top up any oil by simply unscrewing the filling cap, without the aid of pumps for easy maintenance.

X

Level Indicators

Minimum/maximum indicator lights for displaying the amount of oil circulating in the unit.

X

Return Stroke Decelerator

Integrated pneumatic shock absorber for slowing down the rod stroke in the last 10 mm of the cylinder return stroke.
It protects the integrity of the cylinder and of the structure on which it is installed, especially in the presence of high return speeds and high work cycles.

X

Anterior Stem

Front piston rod in C40 steel, thick chromed.

Accessories and Options

End Stroke Mechanical Regulation

The device limits, with centesimal precision, the excursion of the front piston rod.

Limiter of the Power Stroke Lenght

This device, with manual adjustment, allows to preset the lenght of power stroke.

Fixing Flange

It allows the unit to be fixed to the structure.

Die Holder Pad

Allows easy fixing of the mold to the cylinder rod.

Rod End

It converts female (standard) thread to male.

Die Holder Pad with Radial Clutch

Radial coupling device for fixing the mold.

Rod Extension

To interface with the stem of the press, it increases its length.

External Tank

For units in horizontal and vertical working position with rod upwards.

Anti-rotation Rod Group

Complete with bracket, anti-rotation rod, guide bushing and bushing cap.
