Description

Pull clamping elements 4.2180

Double-acting pull clamping element for clamping dies on a press bed or press ram.
The die must be provided with T-slots for the tie rod. The die must be inserted in the correct position and in parallel with the clamping elements.
Monitoring of the clamping and unclamping position by inductive proximity switches. Tie rod and piston are hardened and ground. The hydraulic system is protected against dirt by wiper rings. 

Applications

  • integrated in press rams
  • integrated in press beds
  • in machine tools and equipment
  • when the available space is limited


Special features

  • high operational safety by position monitoring
  • ideal force transmission with centrally arranged clamping elements
  • compact design
  • clamping force from 60 kN up to 164 kN
  • suitable for large clamping edge tolerances (±1.5 mm)
  • no interfering edges when inserting the dies
  • optimum use of ram and bed surfaces
  • clamping at difficultly accessible points
Pull clamping element 4.2180

Pull clamping elements with T-slot 4.2350 and 4.2351

The pull-clamping element with T-slot facilitates a die standardisation by means of T-slot bars or T-nuts on the die.
The hydraulic oil supply is made either through drilled holes in the bed and the ram or through pipes.
Tie rod and piston are hardened and ground. 
The hydraulic system is protected against dirt by wiper rings.

Applications

  • integrated in press rams
  • integrated in press beds
  • integrated in intermediate plate (4.2351 )
  • in machine tools and equipment
  • when the available space is limited


Special features

  • compact design
  • bed and ram can also be used for manual clamping
  • ideal force transmission with centrally arranged clamping elements
  • optimum use of bed and ram surfaces
  • dies are easily adaptable
  • bed and ram can also be used for manual clamping (4.2351)
