• Tolerance of clamping edge height ± 0.15 mm
• The pressure of the machine hydraulics of 160 bar is sufficient for unclamping
• Very sturdy and compact design
• Housing with stainless coating
• Flexible connecting possibilities by 4 hydraulic connections

Application:

The single-acting wedge clamps are suitable for safe clamping of moulds and dies with flat clamping edge in injection moulding machines, punches and presses.

Description:

The wedge clamps consist of a guide housing with one-piece clamping bolt. Clamping cycle: the clamping bolt which is inclined by 6° performs an idle stroke and simultaneously a clamping stroke. The clamping bolt is lowered axially onto the clamping edge. The 6° angle, the spring force in the clamping bolt and the frictional engagement at the clamping point create a self-locking connection. The wedge clamp should preferably be used with position monitoring.
