Abstract

A plane plate for a pressing tool of a press in which the plane plate for activating a punch of the press is 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 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 guide column is parallel with the axial direction. The plane plate in at least a first cross section which between the receptacle and the guiding face runs parallel with the axial direction and along a radial direction that runs so as to be perpendicular to the axial direction has at least a first region with a wall thickness and a first centerline, wherein the first centerline runs at least partially at a first angle of at least 10 angular degrees and of at most 80 angular degrees in relation to the radial direction.
