基于PLC的真空压力铸造智能控制

Intelligent Control of Vacuum Pressure Casting Based on PLC

针对原始真空压铸手工操作高温高危的工作环境,手工测试困难或不可能测试及各种复杂参数控制与监控要求等问题,对真空压铸基本原理及工艺进行了分析,运用PLC设计真空压铸智能控制系统。通过关键参数的实时监控,对真空压铸过程中的温度、压力、速度进行了实施调整,实现了铸件连续生产的智能控制。设计的系统可检测和测量各参数,智能识别故障并报警提示,操作简单,缩短了异常处理时间。

Aiming at the problems of high temperature and high risk working environment manual operation of original vacuum pressure casting,difficult or impossible testing by hand and various complicated parameter control and monitoring requirements,the basic principle and technology of vacuum pressure casting were analyzed.The intelligent control system of vacuum pressure casting was designed by using PLC.The temperature,pressure and speed of the vacuum pressure casting were adjusted by monitoring the key parameters in real time,and the intelligent control of the continuous production of the castings was realized.The designed system can detect and measure the parameters,intelligently identify faults and give alarm warning,easy to operate and shorten the time of exception handling.
