Mini hinge clamp 70 bar

Application
The mini hinge clamp is a low-cost hydraulic clamping element for thinwalled workpieces and reduced space. The special kinematics allow clamping nearly without side loads of workpieces which are very sensitive against deformation. A clamping recess in the workpiece a little bit wider than the clamping lever is sufficient as clamping surface.
This line is designed for the direct connection to the machine hydraulics with a max. operating pressure of 70 bar.

Description
When pressurising the element, the piston moves upwards and swivels the clamping lever over the hinges forwards and at the same time downwards onto the workpiece. The piston force is deviated by 180° and is available as clamping force with virtually no loss of efficiency. During unclamping the clamping lever with swivel contact bolt will be swivelled behind the front edge of the flange, thereby unimpeded loading and unloading of the workpiece is possible. Workpieces which are very sensitive against deformation are clamped nearly without cross loads, if the clamping surface is at the height of the bearing pins of the clamping lever (34  mm above the flange surface). 
The optionally available long clamping lever is provided for customer-specific adaptations.
