网络控制冲孔加工系统的设计与研究

摘要

针对冲孔加工系统的特点和广大中小型冲孔加工企业车间布局不统一的问题,开发了一种基于PLC的网络控制冲孔加工系统,把各个分散的生产车间进行重新整合组建DCS分布式控制系统,形成管理系统和控制系统网络一体化.通过S7-300可编程控制器控制回转工作台的旋转,实现了自动上料、冲孔和下料.采用组态软件WinCC6.0设计动态人机界面,提供与操作人员交互的接口,对冲孔系统的现场工艺操作流程进行全数字化监控.经实际运行表明,系统运行稳定、可靠,取得了较好的经济效益和技术效益.%According to the characteristics of punching system,a PLC network control system of piercing is developed,since the workshop layout is not unified in the majority of small and medium-sized piercing enterprises.The network integration of the management system and the control system is formed by constructing DCS distributed control system with rebuilding dispersed production workshops.In control unit,utilizing S7-300 programmable controller to control the rotation of the workbench implements the automatic feeding,punching and blanking.Moreover,using configuration software WinCC6.0 to design dynamic man-machine interface,providing a man-machine interface to operators,monitor the process of punching operation in digital mode fully.The practical running shows that the system is stable and reliable,obtain good technical and economic benefits.
