Hydraulic Swing
Clamp Unit

HSS

  • For medium and large presses
  • For clamping upper dies
  • For dies or adapter plates with identical measurements and U-recesses
  • Fixed installation on the edge of the slide

Mode of operation

  • A double-acting hydraulic cylinder provides the clamping force.
  • The swinging movement is effected with mechanical guidance.

Description

The hydraulically driven clamping cylinder of the clamp unit generates the required clamping force directly. In order to secure the clamping force, hydraulic pressure must be maintained (e.g. with pilot-controlled check valves). Pressure sensing by the pressure switch on the hydraulic power pack is required. When unclamping, the tie rod is unloaded and then swings back into its park position due to restricted guidance.

  • Fully automatic operation
  • Large clamping dimension tolerance
  • Continuous clamping force monitoring by pressure sensing
  • Minimal installation investment
  • Pratically maintenance free
  • Simple functional monitoring by proximity switches
  • Low operating pressure

  • Pilot-controlled check valves
  • Flow control valves
  • Fittings
  • Hydraulic hoses / Hydraulic accessories
  • Hydraulic power packs
  • Limit switches / cable
