ABSTRACT:
In a forging press of underfloor construction, the vertically travelling frame has a lower crosshead which fits around and is guided on a hollow guide shaft which projects downwards from the table crosshead or platten of the press. The hollow guide shaft serves also as the working cylinder of the press. A working plunger piston which is slidable in the cylinder is coupled to the lower travelling crosshead of the press frame through spherical jointing to eliminate transverse forces on the piston.
