Electromechanical Slide
Lock System

OSV

  • For medium and larger presses
  • For locking the slide during works in the die room or on the press
  • For mechanical and hydraulic presses
  • Requires contour plates which are externally welded to the slide or recesses in the surface
  • Stationary installation suspended under the press crown

Mode of operation

  • An electric motor with gearbox produces the axial movement.
  • The tie rod head performs a 90° rotation at the beginning of the locking procedure and towards the end of the unlocking procedure.
  • The press slide may be locked in any position.
  • The slide lock system supports the mass of the slide and its attached parts.

Description

An electric motor operating via a gearbox causes a spindle nut to rotate. Through this the spindle is moved up and down. The tie rod which is completely extended in its park position first performs a 90° rotation and then moves directly to the slide respectively the contour plate. Thereby, the mass of the slide and its attached parts are secured against lowering. A hydraulic cushion guarantees unlocking of the tie rod even under load (within the possible release stroke). Sticking of the tie rod is impossible. Unlocking of the slide is effected by reversing the sequence.

  • Locking the tie rod in any position
  • Unlocking the tie rod even under load is possible.
  • All important functions electrically monitored
  • Compact dimensions
  • One-motor operation
  • Approval as per safety category 4 on request

  • Plug connectors
