Abstract

A plane plate for a pressing tool of a press in which the plane plate for activating a punch of the press by way of at least one lifting cylinder is displaceable along an axial direction. The plane plate has a link to the at least one lifting cylinder, a centrally disposed receptacle 9 for contacting the punch or a punch holder of the press and at least one at least partially cylindrical guiding face, which for contacting a first guide column is parallel with the axial direction. The plane plate has, in at least a first cross section which runs through the link and the receptacle parallel with the axial direction and along a radial direction that runs so as to be perpendicular to the axial direction, at least a first region between the link and the receptacle, having a wall thickness, wherein the wall thickness in the first region and so as to be spaced apart from the receptacle as well as from the link has at least a minimum.
