Electromechanical Turn
Clamp Unit
ED
- For medium and larger presses
- For clamping upper dies
- For dies or adapter plate with identical dimensions or U-recesses
- Stationary installation on the slide edge
Mode of operation
- An electric motor with gear drive provides the clamping force.
- During the clamping and unclamping movement the tie rod is turned through 90°
Description
By means of a gear drive an electric motor causes a spindle to rotate. Through this a nut and the tie rod connected to it move up and down.
The rotation movement of the tie rod is effected by a friction element. Energy is only required during the processes of clamping and unclamping. The clamp unit is mechanically self-locking. The clamping force is continuously monitored.
- Mechanically self-locking
- Electric monitoring of all functions
- Fully automated operation
- Large clamping dimension tolerance
- Continuous clamping force monitoring
- Limit switches / cables
- Plug connectors
