Abstract
The invention relates to a die for arrangement in a press, wherein the die extends along an axial direction between two end faces and forms an inner peripheral surface between the end faces, wherein the die extends from the inner peripheral surface along a radial direction toward an outer peripheral surface and toward at least one centering surface that is disposed in the radial direction on a first diameter, wherein the die has a pressing zone that is spaced apart from the end faces and, in the vicinity of the pressing zone, the die has a greater maximum first stiffness, at least relative to zones of the die that are arranged on the end faces, compared to a pressing force acting on the inner peripheral surface in a direction of a normal vector, and wherein the maximum first stiffness is at least 10% greater than a minimum second stiffness that is present in at least one zone that is arranged on one of the end faces.
