Toggle joint clamp, hydraulic
max. operating pressure 250 bar.
* at p max. or pD max.
** pD = pressure during differential switching
Hardened steel, burnished, with hydraulic cylinder mounted ready for connection to standard double circuit (see circuit Fig. 1) or differential circuit (see circuit Fig. 2). Oil supply via threaded port.
The clamp is particularly suitable for use in transfer and special-purpose machines. Any thrust pieces can be attached to the sturdy holding arm. With the differential circuit (see Fig. 2 below) the differential piston area A2 of the cylinder is directly connected to P of the pressure generator, while the full piston area is connected by a 3/2-way seat valve.
The clamp, of machine quality, is maintenance-free thanks to its tempered and ground shafts which run in Teflon bearings. As a result of the hydraulic cylinder operation the possible clamping force is the same as the permissible holding force. The large aperture enables unhindered workpiece handling.
Please urgently observe the maximum pressure values in the table above.
