切管机设计毕业论文

一般是看传动比，也就是切割的扭矩要求，这样来配合就可以了，一般切割这个的电机，应该3KW就够力量了。

对切管机控制系统的设计进行了研究。总体控制方案为：利用开关元件、编码器等装置采集控制信号和现场数据，用工控机和可编程逻辑控制器CPU进行数据处理，再通过可编程逻辑控制器和扩展模块的输出信号作用于继电器或变频器，进而实现对切管机工作过程的控制。Have carried on research in cutting the design of the control system of the in charge ofing machine. Overall to control the scheme: Utilize devices such as the component of the switch, encoder,etc. to gather the control signal and on-the-spot data, recruitment accusing of machine and programmable logic controller CPU carry on data processing, and then act on the relay or frequency converter through the programmable logic controller and output signal of expanding the module, and then realize to the control cutting the working course of in charge ofing machine.全文分为四个部分：The full text is divided into four parts:第一部分概述了所要研究的问题及研究的目的意义，并提出了主要研究思路和方法。Part one Have sum up the purpose and meaning of problems and research studied, has proposed thinking and method of main research.第二部分对控制任务进行分析评估，根据PLC与单片机和微机的对比，选定用PLC进行控制，并选定了控制系统的电器元件。Part two Analyze the assessment to the task of controlling, according to PLC comparison with one-chip computer and computer, select and control with PLC, select the electric apparatus component of the control system.第三部分选定拖动方案为液压传动，对液压传动系统的特点进行了分析，介绍了本题所用的液压系统的组成，给出了液压原理图。Part three Select the scheme of pulling to analyze the characteristic of the hydraulic transmission as hydraulic transmission, introduce the hydraulic and systematic composition that the subject under discussion uses, provide the hydraulic principle picture.第四部分设计控制系统。根据工艺流程和控制要求，选定控制方案，编写I/O地址表和控制程序，画出了系统的主电路图和可编程逻辑控制器的端子接线图。Part four Design the control system. According to the technological process and control request, select the scheme of controlling, write I/O address form and control procedure, draw the sub wiring diagram of end of main circuit diagram and programmable logic controller of the system.
