ApplicationThe self-limiting clamping system for quick-release taper tools developed by BERG Spanntechnik is used in conjunction with the proven SSK clamping sets. In this solution the wedge drive itself is rigidly connected to the clamping set via a drawbar. The wedge drive can be directly hydraulically or mechanically actuated. The absolute self-limitation of the system guarantees high mechanical overall rigidity of the interface in conjunction with maximum clamping reliability. The direct hydraulic actuation, in particular, permits extremely small installation spaces with low operating pressures for the complete clamping and chucking system.
Design FeaturesA double-acting cylinder leads directly into a clamping cone which has a very low gradient. During clamping this clamping cone presses the pressure elements resting on it into the similarly tapered housing hole. This displaces the wedge piece in the axial direction. As the wedge pieces rest in windows of the main drawbar, they are also axially displaced (clamping stroke). The cone angle and surface properties are designed to guarantee absolutely reliable self-limitation. In addition to the hydraulic actuation the system can also be driven dry by direction connection to a draw/push-bar. All systems are completely maintenance-free due to their respective surface properties!
AccessoriesAdapters, hydraulic units, clamping force measuring device, volume flow measuring device for stroke control.

Automatic Hydro-mechanical Self-locking C-clamping Systems
The C-clamping hydromechanical self-locking (hydrolock) die clamping system is designed for clamping dies of various widths on press slides. The clamping actuator moves automatically in the T-slot of the press slide between the parking position and the respective die. Clamping and unclamping are performed by a hydromechanical self-locking clamping gear. Hydraulic pressure is at a maximum of 90 bar.
Hydraulic Power Stations for Hydraulic Quick Die Clamping Systems
Hydraulic power stations for quick die clamping systems are designed for actuating hydraulic clamping elements in the forming presses. A large number of electro-hydraulic (HA) or air-hydraulic power stations (HAL) are available depending on the use of the clamping elements and/or hydraulics on the press plunger or on the table, as well as the number of clamping elements.
