基于PLC的旋耕机刀片热轧自动转向控制系统设计

摘要

In the production of rotary blades for hot-rolled,there are problems of low degree of automation,high labor intensity and poor working environment.To solve these problems,this paper designs a PLC control sys-tem for rotary tiller blade hot rolling.Based on the existing production line,the paper analyzes the automatic steer-ing control requirements,proposes the PLC automatic steering control blade,and gives the PLC I/O wiring dia-grams,ladder diagrams and the statement table to achieve blade automatic steering.The controlling system,with fast and dynamic response,is simple and effective.%为解决旋耕机刀片热轧生产自动化程度低、工人劳动强度大以及生产作业环境差等问题,本文设计了旋耕机刀片热轧的自动送料PLC控制系统.该系统在现有旋耕机刀片生产线的基础上,分析了自动转向控制要求,设计了旋耕机刀片热轧自动转向装置,提出PLC控制刀片的自动转向,给出了PLC的I/O接线图、梯形图和语句表等,实现了旋耕机刀片自动送料机构的自动转向.经验证,该系统简单易行、动态响应快、系统控制效果好.
