Hydro-mechanical Clamping Nut

Hydro-mechanical Clamping Nut - HILMA WZ 6.2276

with a tightening bolt:

• max. clamping force: 60 and 100 kN
• max.10 stroke: 2 mm
• exterior diameter 70 and 95 mm

with two tightening screws:

• max. clamping force: 60 to 150 kN
• max.10 stroke: 2 mm
• exterior diameter 70 up to 112 mm

Advantages:

• Temperature resistance up to 120 °C
• Safe clamping with visual clamping force monitoring (as an option)
• High clamping force with low torque
• Easy to retrofit
• Clamping nut with through-hole thread, therefore high adaptability to varying heights of clamping edges and tolerances
• No need for adaptation of the tie rod length
• Easy clamping and unclamping by hand
• Maintenance free
• Maximum force density in the smallest space

Application:

• Clamping and locking of dies on press bed and ram
• When highest clamping force is required in the smallest possible space
• If no hydraulic power unit is available

Description:

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.
Admissible temperature difference ± 20 °C
Temperature resistance up to max. 120 °C.
