Abstract
The limiting of the movement of the stroke of the ram is made by at least one fixed abutment. At least one fixed abutment includes a feeler, which determines the elastic deformation of the respective abutment which is generated by the striking force of the ram. The outgoing signals of the respective sensor are led to a control unit for the adjusting of the height position of the ram. This adjusting of the height position of the ram proceeds via an adjusting motor followed by a gear train. By means of the fixed abutments the position of the lower dead point of the ram relative to the punching tool lower part may be adjusted in accordance with the prevailing conditions. Conclusively, it is also possible to exactly set the depth of immersion of the punching tool upper part with its dies in the punching tool lower part, which thus can amount also to 0 or even less. The height position of the ram which is adjusted in dependence from the striking force exerted on the fixed abutments reduces the overall loading of the punching machine, which loading otherwise would considerably increase at an increasing number of strokes.
