Abstract：

Drive system design of new servo crank presses with switched reluctance was introduced.Based on summarizing the latest development of the drive system of crank presses,a new idea that crank presses were driven by switched reluctance driver(SRD) with servo system was put forward.The flywheel energy was replaced with the energy released by drive system rotation inertia by using the SRD full falling speed.Flywheel and clutch were cancelled.The design principle and method of drive and energy systems were set up for servo crank presses with switched reluctance.The formulas of the system energy were inferred.In view of J21-200 servo press,the design calculations were carried on the system rotation inertia,SRD acting energy in the pressure stroke,the useful energy,the rating work energy and the start and stop time.The conclusion is that the crank presses with switched reluctance have the advantage of simple structure,low price,numerical servo control,saving energy and higher reliability.This kind of machine is estimated to be the development direction of mechanical presses.
