E-AHP Series
BASIC
The entry point for autarkic hydraulic axes
Autarkic hydraulic axes are compact units consisting of hydraulic cylinder and motor-pump unit. They can be controlled like electromechanical spindle units. The servo motor is controlled by means of a commercially available frequency converter.
Our units support all well-known manufacturers such as Siemens, Beckhoff, KEB, SEW, Schneider,...
Compared to electromechanical axes, the E-AHP units are characterized by very high forces and very low wear. Even if always the same positions are approached, this is no problem with these units.
E-AHP basic units are characterized by their simple design. The retraction and extension speeds and forces are the same due to the so-called synchronous cylinder.
• For punching, bending, cutting, pressing, etc.
• Highly precise positioning (< 5 µm)
• Highly precise pressure and force control
• Full 4-quadrant operation (bi-directional push/pull)
PROVE
Synchronized with additional options
Both units, the E-AHP basic and the E-AHP prove, are based on a synchronous cylinder.
While the basic unit only has a high-quality servo motor, the prove unit has additional valves integrated for load holding or other control tasks.
Shut-off valves and the like can also be integrated in the prove axis and thus a performance level of D/E can be achieved.
• For punching, bending, cutting, pressing, etc.
• Press safety
• Performance Level D/E possible
• Highly precise positioning (< 5 µm)
• Highly precise pressure and force control
• Full 4-quadrant operation (bi-directional push/pull)
PERFORMANCE
Highest precision - maximum energy efficiency
These units differ from our E-AHP basic and E-AHP prove units in two features:
1.The E-AHP performance is based on a differential cylinder, this allows and a so-called regeneration mode (rapid traverse) and the entry and exit forces are different. This unit can be built the most compact.
2.The E-AHP performance unit is equipped with a valve block as standard, which offers many possibilities. One of these possibilities is to maintain pressures for a very long time without using energy here.
As with the prove unit, various control tasks can be performed here with the integrated valves. A performance level PL D/E is possible.
• For punching, bending, cutting, pressing, etc.
• Press safety
• Performance Level D/E possible
• Highly precise positioning (< 5 µm)
• Highly precise pressure and force control
• Full 4-quadrant operation (bi-directional push/pull)
