ABSTRACT:
A mechanical, vibration-preventing means to be used on mechanical and hydraulic presses, bar cutters, shearing machines and the like preferably cyclicly working machine tools with a pulse-like pressing process is adapted to absorb the stroke at punching and cutting in plates, bars, and the like articles of metal, plastics or another material by the resilient energy deriving from the deflection of the machine frame instead of being converted into vibrations and noise immediately after break through of the material being converted directly into rotational energy in a flywheel through a roller screw connection. This roller screw connection transforms the translatory movement of the machine tools into rotation. A free engine clutch ensures that the flywheel--accelerated as a consequence of the above procedure--does not start to pull at the structure of the machine during the reverse movement of the machine tool by a force almost as great as the process force immediately before the energy is received by the flywheel, because only very few machine tools of the above type can bear such tensile forces. The energy supplied to the flywheel is subsequently dissipated before the next cycle of the machine.
