Definitions
- the object of the invention is to improve the drive system known from DE-C2 38 03 632 for use on high-speed forging presses. To achieve this object, a reduction in the axial length of the drive system while reducing its mass is desired and is achieved by the characterizing features of claim 1.
- Figure 1 is an overall view of a forging press, partly in section, the
- the forging press consists of a fixed lower cross member 1, a likewise fixed upper cross member 2 and columns 3 connecting these.
- the cross member 1 carries a lower saddle 4 which is opposed by a movable upper saddle 5.
- the upper saddle 5 is moved by a piston 6, which is connected to an upper plate 7, to which the upper saddle 5 is attached.
- a cylinder 8 guiding the piston 6 is firmly inserted into the upper cross member 2 and provided with a bush 9 for guiding the piston 6.
- the piston 6 in the cylinder 8 can be acted upon via a pressure medium supply line 10 in the cylinder cover 11.
- the cylinder 8 and the cylinder cover 11 are connected to the upper cross member 2 by tie rods 27.
- guide rods 54 which are connected at their free ends to the yokes 55 and are guided by bushes 56 in the associated cross member 42.
