Wedge Clamps for Tapered Clamping Edge with Form-fit Safety Step and Position Monitoring

Wedge Clamps for Tapered Clamping Edge with Form-fit Safety Step and Position Monitoring - HILMA WZ2.2404

• Max. clamping force: 25 .. 630 kN
• Adm. retaining force: 35 .. 820 kN
• Cylinder diameter: 25 .. 125 mm
• Clamping stroke: 20 .. 40 mm
• Max. temperature: 160/100 °C (300 °C on request)

Advantages:

• Safety step for form-fit holding of dies or moulds when the pressure drops
• Safe clamping of moulds/dies with tapered clamping edge
• High operational safety by position monitoring and automatic motion sequence
• Very sturdy design
• High safety standard
• Long service life
• Patented design

Application:

Double-acting wedge clamp with a form-fit safety lug at the clamping bolt for clamping dies on a press bed or ram or for clamping dies in injection moulding machines, machines and installations. Preferably for use on the press ram.

Description:

The wedge clamp consists of a hydraulic block cylinder and a piston guided in a housing. The clamping bolt is provided with 20° bevel to clamp on the tapered clamping surface of the mould/die. Based on the internal design of the wedge clamp and the 20° bevel of the clamping bolt, the system is providing internal friction. This patented design has a form-fit safety step in the form of a lug at the clamping bolt, which has the same shape as the adapter on the mould/die clamping edge. In the case of pressure drop (machine failure or down time) the upper mould/die lowers to the safety step onto the safety lug and is safely held by form fit. The clamping bolt can not be returned to the unclamping position and the upper mould/die is safely held.
