1、摘要摘要板簧卷耳机是用于钢板弹簧端部切边（角）和耳部成型的专用设备。该设备采用模块化结构，由PC机与PLC两级计算机进行控制。其中，PLC可编程序控制器作为核心的控制部分，顺序控制完成切边角、卷耳等动作。本设计主要阐述了研究板簧卷耳机的背景，国内外汽车板簧的研究现状以及板簧卷耳机的工作过程。同时简要介绍了PLC实现的功能，及其与继电器控制系统的比较，并根据板簧卷耳机的工作流程，设计其电气控制程序，包括主程序、切边角子程序、卷圆耳子程序、卷包耳子程序、卷1/4耳子程序、压弯子程序，以及定位计算程序等各个部分的流程图绘制、PLC程序的编写。本设计改变了以往使用继电器接触器的现状，具有稳定可靠、
