Abstract

An eccentric press which can be constructed a single connecting rod machine or a twin connecting rod machine is described. The press includes a stroke adjustment means having a support lever which is articulately connected at the joint between the two portions of a lever arrangement. The articulation joint is guided on an adjustable path of movement and the foot point of the support lever is guided variably in its position on a circular arc, the center point of the circular arc coinciding with the position of the articulation point which corresponds to the bottom dead center of the ram. As a result, a change in the ram stroke does not change the bottom dead center of the ram, only one ram stroke being executed per connecting rod revolution.
