【摘要】：邦迪管作为汽车行业大量应用的制动油管,其各项性能指标直接影响车辆驾乘人员的安全。而邦迪管表面防护涂层的好坏直接关系到管材的抗腐蚀、抗冲击性能。随着汽车工业的不断发展,对邦迪管表面涂层生产工艺技术的研究显得更加重要。本文为一条新建的邦迪管PA涂层生产线设计并开发了整套自动化控制系统,通过对整条生产线的组成工艺段进行简要分析介绍,列出被控对象的特点及控制要求,结合作者对类似生产线控制系统的设计集成经验,以经济性和先进性作为指导思想,完成设计和开发任务。该系统选用西门子S120伺服驱动装置作为电机的驱动单元,使用S7-300系列PLC完成整条生产线的集中控制,按照监控层、控制层、设备层的三层结构设计基于Profibus-DP的网络总线结构和驱动控制结构。通过对开卷恒线速度开卷、活套恒张力控制、工艺段温度PID控制及花型盘卷等关键工艺功能的原理介绍和实现过程的阐述,详细论述了本生产线的控制系统中涉及到的与生产工艺有关的实际问题解决方案。生产线的协调控制流程分主令速度控制、入口段驱动控制和出口段驱动控制三部分组成,对基于转矩跟随的矫直机电机同步控制和多管接头跟踪功能在生产线控制系统中的集成应用做了简单说明。系统设计了界面友好的HMI监控系统,在完成主要工艺参数设置和监控的功能之外,通过动画、图形等较直观的形式使界面便于操作和利于维护人员进行故障分析处理。监控系统还包含了完善的安全保护监控及报警提示功能等,对人身设备安全作出稳妥周全的系统保障。
[Abstract]:As a brake oil pipe widely used in automobile industry, Bondi pipe has a direct impact on the safety of vehicle drivers and passengers. The surface protective coating of Bondi tube is directly related to the corrosion resistance and impact resistance of the pipe. With the development of automobile industry, it is more and more important to study the production technology of Bondi tube surface coating. In this paper, a whole set of automatic control system is designed and developed for a newly built Bondi tube PA coating production line. The characteristics and control requirements of the controlled object are listed through a brief analysis of the process section of the whole production line. Combined with the author's experience in the design and integration of similar production line control systems, the design and development tasks are accomplished with the guiding ideology of economy and advanced nature. In this system, Siemens S120 servo drive device is selected as the driving unit of the motor, and S7-300 series PLC is used to complete the centralized control of the whole production line, according to the monitoring layer, the control layer, The design of three-layer structure of equipment layer is based on the network bus structure and drive control structure of Profibus-DP. This paper introduces the principle and realization process of key process functions, such as unwinding constant linear speed, loop constant tension control, temperature PID control of process section and pattern coil, etc. The practical problems related to the production process involved in the control system of the production line are discussed in detail. The coordinated control flow of the production line consists of three parts: the main speed control, the inlet drive control and the outlet drive control. The integrated application of synchronous control of straightener motor based on torque following and tracking function of multi-tube joint in production line control system is briefly described. In addition to the functions of setting and monitoring the main process parameters, the interface is easy to operate and the maintainers can analyze and deal with the faults through animation, graphics and other intuitive forms. The monitoring system also includes perfect function of safety protection, alarm and prompt, and makes a safe and comprehensive system guarantee for the safety of personal equipment.
