As soon as the actuator output 24 or the two pistons 12 and 22 have reached their starting position, the actuator output 24 opposes the inward movement of the blank with a large force, the blank then being reshaped in the forming die by the press die (FIG. 28).
- the forming device is now a new one
- FIG. 34 illustrates that during a
- Actuator 24 applied shear force and the travel (stroke from starting position) of the Aktuatorabtriebs 24 as a function of the cycle time t.
- the dashed line shows the travel s
- the solid line shows the force F.
- Figures 35 and 36 show a variant of the first and second drive unit, in which instead of servo valves speed-controlled pumps are used.
- the drive unit 10 x includes next to the already
- the pump 118a is connected to the first piston chamber 11 via the line 15a.
- the second drive unit 20 x comprises, in addition to the components already described, a pump 128 a driven in a speed-controlled manner by an electric servomotor 128 b.
- the pump 128 a is connected to the second piston chamber 21 via the lines 25 a and 25 b.
- An additionally existing membrane or bladder accumulator 127 is connected to the two lines 25a and 25b via a check valve 127a and 127b, respectively.
- the two servomotors 118b and 128b are replaced by the controller 50 (instead of the servo valves 18 and 28)
