1、华北电力大学科技学院本科毕业设计(论文)金属锯屑挤压机液压控制系统的设计摘要随着现在社会的发展,机械、液压、电气等科学技术的进步,挤压机的应用越来越广泛,渐渐成为机械行业不可或缺的加工机械。本文根据金属锯屑挤压机(又名金属锯屑压块机)的具体结构,进行液压系统的设计。首先,根据金属挤压机的具体工作原理,深入研究液压传动技术,分析其在实际应用中的功能。然后利用不同液压元件的作用,进行合理的连接来实现其所能完成的任务。同时,对PLC技术进行研究,了解各元件的作用。根据设计好的液压传动原理图,画出控制流程图;并根据设计确定I/O点数,选用了合适
2、的可编程控制器,并给出了I/O分配表和I/O接线图,以及编写了PLC控制系统的程序。最后利用FESTO仿真软件对所设计的金属锯屑挤压机液压系统进行了控制系统的仿真,进一步证明了本次设计的控制系统能按挤压机的工作过程进行工作。关键词:PLC;液压传动;挤压机;FESTO仿真Opinionsandsuggestionsontheparty'smasslineeducationalpracticeAccordingtothecentralandprovincial,municipalunifieddeployment,accordingtom
