摘要
设计了高强钢筋切断机的整体结构,对其定长系统和切断系统的设计方案进行了详细介绍,包括各部分的功能及工作原理,确定了切断机构液压系统的工作参数。从技术需求出发,设计了切断机的控制系统,规划了控制流程,完成了电路元器件的选型和PLC程序的编制。实现了钢筋自动定长切断,可设定实时牵引速度显示,故障报警、自动换刀等多种功能,自动化程度高。在理论和设计计算的基础上,进行了样机的试制,该样机实现了机电液一体化,改善了传统牵引速度慢、定尺精度误差大等缺点。
In this paper, the overall structure of high-strength steel bar is designed, the design scheme of its fixed-length system and cutting system is introduced in detail, including function and working principle of each part, and then the working parameters of the hydraulic system are determined. From the technical requirement, the control system is designed, the control flow is programmed, the selection of the circuit components and the programming of PLC are completed. Automatic fixed-length and cutting can be realized, real-time traction speed display, fault alarm, automatic knife changing and other functions can be set up, and automatic level is high. On the basis of theory analysis and design calculation, a prototype is made, it realizes the integration of electromechanical fluid, the shortcomings of the conventional traction speed and the error of the fixed ruler precision are improved.
