Applications
- preferably on press beds
- for clamping and locking dies and shuttle tables
Clamping
First, the cylinder piston pushes the clamping lever into the clamping position to the die clamping edge. Released by the hydraulic sequence control, pressure is then applied to the clamping and locking mechanism. Once the clamping force is built up, the clamping element is self-locking. This mechanical lock prevents unintentional unclamping of the die even if there is a pressure loss.
Unclamping
For unclamping, the clamping and locking mechanism is hydraulically unlocked.
Released by the hydraulic sequence control, pressure is applied to the cylinder piston which pushes the clamping lever into the unclamping position. Unclamping and clamping positions are monitored by inductive proximity switches.
