Energy Saving Drive for Forming Equipments

Abstract:

Energy saving in manufacturing is the key to reduce energy consumption of unit GDP. Forming equipments are one of the biggest energy consumers. The basic reason of high energy consumption and low efficiency for current forming equipments is the mismatch between uncontrollable driving characteristics and the variable loads in forming processes. Complex transmission and control mechanisms are needed, wasting a lot of energy. The basic principles of driving were put forward to realize energy saving for forming equipments: faster in virtual strokes, slower in working strokes, stop when idling and recycling excessive energy. The servo driving based on large AC servo motors can make the driving and forming loads match each other well, realizing not only high automation and intelligence, but energy saving greatly as well. Theoretical analysis and experiments showed that by adopting AC servo driving the crank presses, hydraulic presses and screw presses could get the energy saving results of 25-70%.
