Abstract
The invention relates to forging machines which are provided with in particular four rams which are arranged offset at 90.degree. to one another in a cruciform manner in one plane, act radially upon the workpiece, guided longitudinally in the system axis, and are equipped with tools. Piston-cylinder units provided for driving the rams are dimensioned for the entire stroke of the rams. The object of the invention is a simple, secure setting of the stroke-end position of the rams corresponding to the current tool setting or width. This object is attained in that the stroke of each ram (2) or the cylinder (4) connected to it can be limited in the inner stroke-end position by displaceable stops (17, 18, 19) arranged between the machine frame (1) and a projection (14b) on the ram (2) or cylinder (4). It is particularly advantageous to use as the stops spacer members (18, 19) in the form of plates pivotable about an axis parallel to the ram axis and having eccentric extensions (24, 25) pivoting into and out of the path of the projection (14b).
