preSSeS wiTh ServodireCT TeChnology
automatic forming systems are created for a broad range of parts. The presses are driven directly by torque motors which permit highly dynamic forming processes thanks to their high torque. The lack of a flywheel and clutch / brake combination makes the presses flexible, energy efficient and cuts down the maintenance required.
proGrAmmAble Slide moTion curveS The use of highly dynamic torque motors permits straightforward and rapid programming of different movement profiles in one press cycle. This means the slide kinematics can be quickly and easily adapted to the process parameters of the die and the automation system, and optimized for a high stroke rate.
oScillATinG STroke mode
oscillating stroke mode permits user-programmable slide stroke heights. The reversing movement of the torque motor means that the eccentric drive of the slide has an oscillating motion and alternates between forward in one stroke and backward in the next stroke. This significantly improves cycle count and energy efficiency.
individual programming of the slide motion reduces the cycle time while keeping the forming speed constant.
Servodirect technology allows the slide motion to be programmed individually.

Significant increase in productivity compared to conventionally driven mechanical presses maximum production flexibility due to
user-programmable stroke heights and motion sequences increased parts quality and die lives due to motion
sequences optimally adapted to the particular forming requirements
Greatest availability for production mode Best suited for processing high-strength steels
Short delivery times and optimized spare part management due to standardized modules Shorter die tryout times because of setup and
tryout functions with hand wheel
lower energy costs due to efficient drive solution Easier maintenance compared to conventionally driven mechanical presses, because there are fewer mechanical components.

enerGy mAnAGemenT
Energy accumulators can be used as an option in order to reduce the connected load. This means energy is returned to the energy accumulator during the press cycle in the
generative braking phase. This stored energy is available during the
subsequent motor acceleration phase, without imposing any additional load on the electrical system.
reliAble componenTS The monoblock press body is implemented as a stress-free annealed welded structure. The eccentric gears have a double herringbone profile to provide axial guidance and to reduce noise. The slide roller guide is preloaded to eliminate play. This results in components that guarantee high availability of the machine.
TryouT
Starting up new dies demands the greatest flexibility. The setup speed can be varied by a hand wheel. The slide can be stopped in any position and the direction of movement can be reversed if required. The quick-lift function makes it possible to move the slide to the maximum top reversing point at any moment during the setup procedure.
