摘　　要：在分析折弯机成形特点基础上,本文提出了数控折弯机的必备功能,设计出分布式的计算机控制系统,由一台工业控制机和两台PLC组成,实现了对折弯机的智能控制。文中介绍了控制系统硬件配置和软件设计,着重分析了编程软件和通信程序。控制系统具有操作方便,可扩展性好,模块化强,可移植性好,网络通信可靠以及性价比较高等特点。On the basis of the bender forming characteristic analysis, this article gives necessary function of NC bender and designs distributed computer control system, which controlled the bender intellectively with one industrial computer and two PLC. The article introduces the control system hardware configuration and software design, emphatically analyzes the programming software and communications procedures. The control system has characteristics such as operation conveniency, good expandability, modularization strong, good probability and high network communication reliability price superiority.
