Summary:A first eccenter sleeve allocated to the drive of the devices operative for the balancing of masses is drivingly connected to the eccenter shaft by means of a displaceable locking bolt. The first eccenter sleeve is provided with pins and slide rings engaging into slots in the second eccenter sleeves. The second eccenter sleeves are connected via punch connecting rods to the ram of the machine. Slides are supported in the machine frame, which slides can be moved into slots provided in the second eccenter sleeves. Accordingly, all three eccenter sleeves can be held against rotation on the eccenter shaft. The drive connection between eccenter shaft and all eccenter sleeves proceeds accordingly via one single connecting member, namely the locking bolt. And this locking bolt operates together with one eccenter sleeve. Accordingly, no splined shafts which must be machined extremely precisely but are prone to knock out during operation are necessary.
