【Abstract】 In order to solve the problems of high energy consumption and low control precision of conventional friction screw presses,and by using the servo motors of switched reluctance driver(SRD) to reduce the speed and drive the screw pairs to change direction,the precision force-energy control principle of SRD servo screw presses was put forward.The structures of electric servo screw presses for forging,bending and brick-making were introduced.The vertical and horizontal axis type servo elbow screw presses were designed.The characteristic comparison was carried out,and he test and analysis results show that the new servo screw presses have the advantages of exact process parameter numerical control,and the electric servo screw press driven by SRD for making brick achieves 70% energy saving in experiment contrasting the friction screw press.The SRD screw presses can satisfy the different process demands in various industries and realize the targets of automatic and intellectual production.更多还原
