Single shaft eccentric punch press with slide connected at four points

摘要

The pressure columns (16, 17) are connected to the slide (3) via ball-and-socket joints (42-45). The sockets (44, 45) are situated inside the pressure columns (16, 17) and the balls (42, 43) are arranged above the slide (3), to which they are connected. This means that when the slide (3) is loaded in an excentric fashion, no bending moments are transferred to the pressure columns (16, 17). The entire underside of the slide (3) is available for accommodating connecting elements for a tool.
