Wedge Clamps for Flat Clamping Edge

double acting, operating force 35 up to 120 kN, hydraulic clamping and
unclamping, without and with position monitoring at the side

Double-acting wedge clamps are particularly suitable for safe clamping of dies with flat clamping edge on a press bed or ram or for clamping dies in injection moulding machines.
The wedge clamp consists of a hydraulic block cylinder and a two-piece mechanical clamping bolt.
Clamping cycle: the clamping bolt with thrust pad first performs an idle stroke. When the inner stop is reached, the clamping bolt is lowered onto the clamping edge. The 5° angle of the thrust pad has been determined so as to ensure that despite self-locking the hydraulic pressure required for clamping is not higher than that required for clamping.
Since the clamping force is vertically transmitted to the clamping point, no side loads occur.
The wedge clamp is available with or without position monitoring.

Special features

• the clamping piston does not retract in the case of pressure drop
• sizes of 25 kN, 50 kN and 100 kN
• high operational safety by position monitoring and automatic motion sequence
• very sturdy and compact design
• special versions on request
• well-proven clamping element with high degree of safety and long service life
• retracting clamping bolt ensures unimpeded die and tool change
