Cutting impact damping with parallel holding for low stress on the press when the punching material breaks through
The service life of the press and cutting tools is significantly
increased by the integrated cutting impact dampers, as the ram is subjected to less stress. As a result, the ram is less worn and damage is avoided. Another advantage is that noise and vibrations during punching are reduced to a minimum.
The cutting shock absorber consists of a cylinder whose pressure chamber is filled with oil. If the press ram initially moves at normal speed, the speed at which the material is processed increases many times over. A high counterpressure is created in the cutting shock damper, which damps the cutting shock. The oil is displaced by the cutting shock and is refilled during the upward movement of the press ram when the piston moves to its initial position.
