6.2210 Sliding clamp, mechanical
Function
The sliding clamp is manually placed in the T-slots and screwed against the die clamping edge.
Once the high-pressure spindle has been adjusted to suit the height of the clamping edge, the clamping force is built up by turning the hexagon nut in clockwise direction.
The clamping force achieved depends on the set tightening torque of the torque wrench.
Installation note
Before applying the tightening torque, the high-pressure spindle must be screwed against the clamping edge so that there is no play.
If the parts are not rigid, tighten the high-pressure spindle using the hexagon nut until there is no play.

Clamping block with integral high-pressure spindle
Function
The sliding clamp is manually placed in the T-slots and screwed against the die clamping edge. The clamping force is built up by turning the hexagon nut in clockwise direction.
The clamping force achieved depends on the set tightening torque of the torque wrench.
Installation note
The clamping blocks with integral high-pressure spindle can be mounted on spacer bars.

6.2270 High-pressure spindle
Function
Following manual positioning of the high-pressure spindle against the clamping edge, the drive spindle is operated by turning the hexagon nut. Thus, the clamping force is transmitted in axial direction to the clamping point by the wedge system. The required clamping force is achieved by selecting the appropriate torque on the torque wrench (see force-torque diagram on the data sheet). For unclamping, proceed in the reverse order.
High-pressure spindle 6.2270, mechanical
6.2273 Clamping nut, mechanical with clamping force display and through hole
Function
Following manual positioning of the clamping nut against the clamping edge, the integral gear and the Belleville springs will be preloaded by turning the hexagon nut. As a result, a high clamping force is generated with a small
torque. The required clamping force is reliably displayed by clamping force display and the integrated Belleville spring assembly ensures reclamping of the clamping nut in the case of clamping edge changes.
WZ 6.2273 Clamping nut, mechanical with clamping force display
6.2274 Clamping nut, mechanical with through-hole thread, without clamping force display
Function
Following manual positioning of the clamping nut against the clamping edge, the integral gear will be operated by turning the hexagon socket.
As a result of the gear transmission, the tightening torque is multiplied. To reliably ensure the required clamping force, we recommend using a torque wrench.
Clamping nut 6.2274 with through-hole thread, without clamping force display
6.2275 Clamping Nut, Mechanical with blind hole thread, without clamping force Display
Function
Following manual positioning of the clamping nut against the clamping edge, the integral planetary gear will be operated by turning the hexagon nut.
As a result of the gear transmission, the tightening torque is multiplied. To reliably ensure the required clamping force, we recommend using a torque wrench.
Clamping nut with blind hole thread 6.2275
6.2276 Clamping Nut, Hydro-Mechanical with through-hole thread and optional clamping force display
Function
Following manual positioning of the clamping nut against the clamping edge, the integral hydraulic cushion is preloaded by turning the hexagon socket. A low torque is transmitted to a high clamping force.
In the case of versions without clamping force monitoring, use a torque wrench to ensure safe and defined build-up of the clamping force.
In the case of versions with clamping force monitoring, the clamping force indicator pin will project by approx. 2.5 mm when the clamping force is reached.
