Abstract
Devices are provided for detecting a mutual reference position of tool parts of a pressing tool, e.g., a punch and die. The device include (a) first and second reference elements that are moveable, by the pressing device, into a relative position that corresponds to a predetermined relative position of the first tool part and the second tool part as mounted in the mountings; (b) a control pressure generator that generates a control pressure when the first and second reference elements are moved into the relative position; (c) a switch that is activated by the control pressure; and (d) a detection unit that is activated by activation of the switch to detect the relative position of the first and second reference elements.
