Levers steel plate.
Hinge pins stainless steel.

Lever parts galvanised.
Pneumatic cylinder, double-acting.
With magnetic piston for end position feedback.
Clamp trivalent passivated.
Complete with tempered, trivalent passivated thrust screw with protective cap.

Pneumatic clamps have the following advantages compared to hand clamps:
The operator is relieved of frequent clamping.
Several clamps can be activated at the same time and can be closed in a specific sequence.
Single or multiple clamps can be activated from varying positions by machine control or hand control.
Because of the toggle system:
– the clamp remains closed if the air supply fails.
– the air consumption is low due to the large end ratio.
– pivoting the clamping arm achieves a large opening travel.
– optimum force and movement ratios are achieved.

VL = air consumption per complete cycle in dm³ at 6 bar.

The schematic diagram for the simplest control of one or several pneumatic clamps is shown here. When constructing complete switching systems consult a well known manufacturer of pneumatic valves who can also supply all the required connectors and fittings.

Le forze F1 e F2 riportate nella tabella rappresentano le forze di tenuta; F3 e F4 sono forze di serraggio.

Per scegliere le giuste dimensioni del dispositivo di serraggio, per le ginocchiere pneumatiche viene indicata oltre alla forza di tenuta, anche la possibile forza di serraggio a 6 bar di pressione atmosferica. F3 è la possibile forza di serraggio che il tenditore esercita all'estremità del braccio di spinta, F4 è la forza che esercita sul lato del fulcro.
