Extend Die Life, and Save Time and Power
The precision and capability in slide motion not only adds flexibility for metal formers, but pays dividends on the tooling side. Significantly reduced vibration of the slide and its precision movement, again, courtesy of servo drives, dramatically extends die life. Another die-life-friendly attribute: Because the flexibility of servomechan-
Significantly reduced vibration of the slide and its precision movement, courtesy of servomechanical press drives, dramatically extends die life.
ical technology enables multiple processes and process steps in a single press, metal formers do not need to stretch tooling across multiple machines, where differences in slide and other machine tolerances can cause excessive die wear. Save produc- tion time by performing more work in a single press, and reduce press idle time by eliminating the need to transfer tooling and parts.
This leads to another servomechan- ical-press advantage: power savings. This technology only uses power when the press is working. Traditional
mechanical presses rely on kinetic energy stored in a flywheel to perform work, so more tonnage requires a big- ger, heavier flywheel turning faster than before. Thus, according to Seyi officials, servomechanical presses, without fly- wheel assemblies, occupy smaller foot- prints and consume less energy.
Pendulum motion—available in ser- vomechanical presses—assists in reducing power consumption. Tradi- tional mechanical presses must com- plete a full turn for each stroke, with most of the energy wasted as these presses only perform work at the very bottom of the stroke where they can deliver full force. Pendulum motion enables full pressing force higher in the stroke, meaning increased hit rates and less power utilization.
Noise reduction represents a less- considered benefit of servomechanical presses. Flywheels are ear-aching fea- tures of mechanical presses. Elimina- tion of the flywheel can cut machine noise by as much as 20 db. MF
