Punching Machine Driver Research Based on Pulse Electromagnetic Force Actuator

Abstract

Punch variety of drives, hydraulic, motor type is also commonly used. Conventional press drives both in terms of simplicity of the structure also in terms of effectiveness of control are present many problems. As is a background on the background of press drive innovative design, research on pulsed electric-magnetic field driven punch. Thanks to electro-magnetic direct drive, the system structure is simple, convenient control flexible, changing the timing and amplitude of excitation pulse, can change the speed and direction of movement of permanent magnet ring and have the output force of significant features. From the design on the effect of pulse electromagnetic drive punch, its index relative to the mechanical structure has improved, such as stamping frequencies up to 300 times/min, noise less than 80dB, volume reduction of cent, reduce the weight of 60%. This structure can greatly improve the working speed of the punch, while simplifying punch drive mechanical structure.
