Research Of The Main Drive Of CNC Turret Punch Driven By Servo Motor

This paper analyzed many advantages of the servo motor-driven main drive of the CNC turret punch which performs much better than the conventional main driven structures. It studied the servo motor-driven main drive system which conforms to the CNC punch trend of development. By reasonable multi-bar force increasing mechanism adopting and design, it deeply researched the main driven structure kinematics and the motion law of each related component as well as the serve motor type selection. Based on these researches, it used SolidWorks and dynamics analysis software ADAMS to do the entity modeling and the dynamic analysis to the main driven system and optimized the main driven system by minimum the crank torque. By doing this it obtained the main driven system most superior size structure. Finally, it analyzed the punch precision and the performance of the main drive system developed and confirmed that the main drive system we designed has achieved the anticipated research performance aim.
