Electro-mechanical clamping elements
No hydraulic, automatic clamping of dies on the ram, blank holders and machines at ambient temperatures up to 70C.
Electro-mechanical clamping elements for maximum operational reliability as a result of mechanical self-locking. Recommended for applications where a hydraulic system cannot be used. All elements are suitable for retrofit and for installation in original equipment. The result is shorter downtimes by minimizing the set-up times, thus more effective machine uptimes.

Wedge clamps 5.2670
Description
The clamping bolt of the wedge clamping elements is operated by a 24 VDC direct current drive via a snail transmission and a spindle stroke transmission.
The self-locking spindle lifting gear stops the actuator in case of power failure and maintains it safely in the reached position. During clamping, the clamping bolt is moved with low inclination onto the straight clamping edge. The clamping bolt is completely retracted in the guide housing in off-position.
The wedge clamp is equipped with an integrated position monitoring. In addition, fault messages can be output. The wedge clamping element is controlled via a control module equipped with different data interfaces.
Wedge Clamps, electro-mechanical 5.2670
5.2610 Angular clamps
Function The angular clamping element driven by an electric motor is automatically moved to the clamping edge of the die by an electrically driven lead screw. The clamping element is guided in the T-slot of the press. Power transmission from the clamping element to the clamping edge of the die is ensured by the rotation of the motor, by a flexspine gear and a wedge system. Advance movement: Driven by an electric motor, the angular clamping element is moved to the clamping point Clamping movement: The clamping force is transmitted to the clamping point in the axial direction of the angular lever The clamping force and the clamping and unclamping positions are monitored by inductive proximity switches. The clamping force is maintained by mechanical selflocking, even in the event of power failure.

5.2620 Tenon-type clamping elements
Function:
The rotation of the motor is converted into a grip and pull movement of the clamping claws by the flexspline gear and the lead screw.
For clamping, the claws grip the tenon of the clamping point and pull it towards the clamping element.
The clamping force and the clamping and unclamping positions are monitored by inductive proximity switches. The clamping force is maintained by self-locking.

5.2640 Swivel and pull clamps
Function:
The rotation of the motor is converted into a swivelling movement and a stroke of the tie rod by the flexspline gear and the lead screw.
For clamping, the tie rod is swivelled by 90°, starting at the unclamping position, and pulled towards the clamping position.
The clamping force and the clamping and unclamping positions are monitored by inductive proximity switches. The clamping force is maintained by self-locking.
Swivel and pull clamp 5.2640
5.2650 Swing clamps
Function:
The rotation of the motor is converted into a swinging movement and a stroke of the tie rod by the flexspline gear, the lead screw and the control pin.
The tie rod swings out by max. 15°. The clamping force is transmitted to the clamping point in the axial direction of the tie rod. The clamping force and the clamping and unclamping positions are monitored by inductive proximity switches. The clamping force is maintained by self-locking.
