2.1400 Spring clamping cylinders
Applications
Unpressurised long-term clamping of moveable machine parts, dies, fixtures, pallets and workpieces
Function:
The force of the spring clamping cylinder is mechanically transmitted to the tie rod or the clamping spindle by a pre loaded Belleville spring assembly. The hydraulic connection is only required for unclamping the clamping cylinder.
Special features
- large choice of clamping forces
- long service life by low-friction Belleville springs placed between hardened and ground thrust washers
- piston secured against rotation
- oil ports radial and axial
- easy installation
Spring clamping cylinder 2.1400
Hollow-piston cylinders 3.1403 , spring clamping
Manual positioning of the element on the die clamping edge.
Unclamping by the application of hydraulic pressure to the piston and clamping by spring force. By means of the T-bolt the die is clamped against the clamping surface of the press ram or bed.
Applications
- unpressurised long-term clamping of dies or fixtures on press beds and rams
- when the available space is limited
Special features
- hydraulic supply is only required for unclamping, i.e. for a short time
- ideal force transmission
- convenient and compact design with gripping surface
- no interfering edges when inserting the dies
- easy retrofit
