Abstract

A plane plate for a pressing tool of a press in which the plane plate activate a punch of the press by way of at least one lifting cylinder that can be displaced along an axial direction. The plane plate has an upper side that points in a first axial direction and a lower side that points in a second axial direction counter to the first axial direction, a link to the at least one lifting cylinder, a centrally disposed receptacle for contacting the punch or a punch holder of the press, as well as at least a first at least partially cylindrical guiding face which for contacting a first guide column is parallel with the axial direction, and a second at least partially cylindrical guiding face which for contacting a second guide column is parallel with the axial direction; wherein on the lower side of the plane plate the first guiding face has a first lower end and the second guiding face has a second lower end, wherein the first lower end and the second lower end in relation to the axial direction are disposed at mutually dissimilar heights and thus are disposed so as to be mutually spaced apart in the axial direction.
