Electromechanical Swing
Clamp Unit

ESS

  • For medium and larger presses
  • For clamping upper dies
  • For dies or adapter plates with identical dimensions and U-recesses
  • Stationary installation on the slide edge

Mode of operation

  • An electric motor with gear drive provides the clamping force.
  • The swing movement is carried out by means of a mechanical guide.

Description

By means of a gear drive an electric motor causes a nut to rotate. Through this a tie bolt and a tie rod attached to it are moved up and down. The swing movement is effected by restricted guidance. When the unit is unclamped and the tie rod swung out the clamping area is completely free. Energy is only required during the process of clamping and unclamping. The clamp unit is mechanically self-locking. The clamping force is monitoring continuously.

  • Mechanically self-locking
  • Electric monitoring of all functions
  • Fully automated operation
  • Large clamping dimension tolerance
  • Continuous clamping force monitoring

  • Limit switches / cables
  • Plug connectors
