Abstract

Improvements in rapid clamping devices for fastening without tools and workpieces or similar, in places of attachment in machines, especially of upper tools in press brakes, from a central place, characterized by comprising a central manometer impeller with accumulator of force, as a central unit from which pressure transmitters are arranged that go to clamping devices for the tool, work piece or the like, and because the force accumulator does not receive and accumulate force until after the minimum working pressure is achieved in the fastening devices.
