Description

Swivel and pull clamp 2.1833

double acting with 2x45° swing angle
The clamping element consists of a hollow-piston cylinder and a swing cylinder. The tie rod held in the hollow-piston cylinder is provided with teeth which engage in the toothed rack of the swing cylinder. The clamping position is pneumatically monitored. Optionally, monitoring is also possible by inductive proximity switches. 

Applications

  • on presses and high-speed punching presses
  • when the available space is limited


Special features

  • suitable for retrofitting
  • ideal force transmission
  • compact design
  • optimum use of ram and bed surfaces
  • clamping at difficultly accessible points

Pivot and pull clamp 2.2185

double acting, with 15° tilting angle
A control mechanism translates the stroke of the double-acting piston into a tilting and lifting movement of the tie rod. For releasing the die, the tie rod pivots by 15°. The clamping force is transmitted to the clamping point in the axial direction of the tie rod. The clamping and unclamping positions are monitored by inductive proximity switches. Temperature range up to 85°C.
Higher temperatures on request 

Applications
Automatic clamping of dies on press rams

Special features

  • clamping stroke 10 mm, which means high adaptability to varying heights of clamping edges
  • high operational safety by position monitoring and automatic motion sequence
  • the tie rod can be pivoted, therefore no collision edges when inserting the die
  • optimum utilisation of the ram area
  • easy installation
  • very suitable for retrofitting

Swing sink clamp for exterior clamping 2.2230

double acting, with 2 x 45° swing angle
The piston is guided by a control bolt so that during the stroke movement a rotation of 45° is effected.
For clamping, the tie rod is rotated by 90° from the unclamping position and pulled against the clamping surface through the existing clamping slots.
Monitoring of the unclamping, change-over and clamping positions by inductive proximity switches. 
The swing mechanism is protected by a spring-loaded overload protection and equipped with emergency stop.

Applications

  • direct fixation on press beds and rams
  • when the available space is limited


Special features:

  • suitable for retrofitting
  • ideal force transmission
  • compact design
  • high operating safety by position monitoring, emergency stop and overload protection
  • suitable for large clamping edge tolerances (±1.5 mm)
  • no protruding parts in the changing area when inserting the dies
  • and thus optimum utilisation of bed and ram surfaces
  • clamping at difficultly accessible points
  • tie rods available up to a length of 2,000 mm

Wedge swing clamp 2.2240

double acting, with 15° tilting angle
with mechanical lock

A wedge converts the stroke of the double-acting piston into a stroke of the tie rod.
In order to release the die, the tie rod pivots by a maximum of 15°.
The swing movement of the tie rod is performed by a separate swing cylinder which is operated by sequence valves.
The clamping force is transmitted to the clamping point in the axial direction of the tie rod. The clamping and unclamping positions are monitored by inductive proximity switches. 
The mechanically-locked wedge prevents unintentional unclamping of the die even if there is a loss of pressure.


Applications:

  • on press beds and rams
  • when the available space is limited


Special features:

  • clamping stroke 9.5 mm, which means high adaptability to varying heights of clamping edges
  • high operational safety by:
    - mechanical lock
    - position monitoring
    - automatic motion sequence
  • only 2 hydraulic connections
  • very suitable for retrofit
