| 摘 要： | 折弯机在钣金制造加工中具有十分重要的地位。针对液压折弯机生产效率低、折弯精度不够高的现状,提出了一种基于伺服电机直接驱动的全电动折弯机数控系统。以PLC作为系统的下位机,触摸屏作为上位机,采用并行结构方式作为折弯机的同步控制方案。该系统结构简单,人机交互方便,可维护性和可移植性好;实验验证Y轴上的定位精度达到了±0.01 mm,重复定位精度达到了±0.001 mm,能够很好地满足折弯机对同步控制的要求。

| Abstract: | Press brake is vital in the manufacturing process of sheet metal.According to the disadvantages of hydraulic press brake in productivity and positioning accuracy,a new system of press brake driven directly by servo motor was presented.In the system,PLC was used as slave unit,and touch panel as master unit and the parallel structure mode was adopted as the synchronous control method.This system has simple structure,excellent performances on HMI,maintainability and portability.Experiment results show that the... |
