The invention relates to a hydraulic press, preferably for punching curved metal products, ζ B. of bottoms for containers, consisting of a lower one connected to a die Traverse, with attached power cylinders, the piston rods of which form the pillars of the press and which are provided with a removable punch at their outer ends by means of threads upper traverse are releasably connected in such a way that the upper traverse is threaded through onto the provided ends of the piston rods screw-on anchor nuts against on the piston rods arranged stop surfaces can be tightened.

Such known presses have the disadvantage that the effects of in the piston rods the possible bending moments occurring in the hydraulic press cannot be prevented, where & i it is difficult to self-center
