摘 要

钢帘线是轮胎的组成方面占重要部分，它的质量直接地影响轮胎的质量。它是以粗细为5.5毫米的高碳钢丝为原材料，拉拔直到变为我们所需要的细钢丝。在其生产工艺中，拉拔到指定直径至关重要，因而研究其直径控制方法，主要表现为对拉丝机系统的控制。

拉丝机将钢丝拉拔到指定直径的流程主要如下：先将未经拉拔的钢丝原料由放线设备传递给拉拔部分，而拉拔部分一般有5-10个电机。原料经过拉丝模和电机的多次传送后，就被拉成了指定的直径。同时，各个拉拔机应该要有冷却装置，以避免由于高温引起的受损。然后，拉拔完成的钢帘线会被传给收线电机，卷筒收线达到指定长度时，系统停止运行。拉丝机系统主要组成有放线部分，拉拔部分以及首先部分，而最为重要的部分就是拉拔部分。

本次课题是钢帘线直径控制的研究，使用的是直进式拉丝机。本文介绍了钢帘线的制造工艺，国内外近况以及直径控制机理。研究对象为8个拉拔机组成的拉拔系统，而收线部分本次研究中不打算深入。拉拔电机均由变频器控制。这里用交流变频调速技术和PLC相结合的控制方案。拉拔系统各级之间依靠各个拉拔电机的速度差。同时，也利用钢帘线张力的调节来实现同步协调。拉拔电机速度由控制机给定。出线速度即为8#拉拔电机的给定速度，根据速度链关系可得到前面7号电机的速度，并由PLC来逐一设定。同时，作为张力传感器的调谐轮会检测到卷筒之间钢丝的张力。再与设定的张力信号通过闭环PID调节，调整对应的变频器的频率来调节另外7号电机的转速，以实现张力恒定。

本文使用软件Autoshop来编写梯形图程序，构建钢帘线的直径控制的硬件系统框架。这是汇川PLC的编程软件。使用HMI对应的Ino Touch Editor软件来编制人机界面；并在实际硬件平台上成功完成了速度链的仿真测试。

Abstract

Steel cord is an important part of the composition of the tire, and its quality directly affects the quality of the tire. It is made of high-carbon steel wire with a diameter of 5.5mm, drawn into a high-carbon steel wire plated with brass and then drawn into a thin wire made of thin wire twisted. In its production process, drawing to the specified diameter is essential, so the study of its diameter control method, mainly for the wire drawing machine system control.

Drawing machine to pull the wire to the specified diameter of the process are as follows: first unplanned steel wire raw materials from the line to the pull part of the drawing, and drawing part of the general 5-10 motor. After the wire material passes through the drawing die and the motor several times, it is drawn into the designated diameter. At the same time, each drawing machine should have a cooling device to avoid damage caused by high temperature. Then, the drawn steel cord will be passed to the take-up motor, the system will stop running when the roll reaches the specified length. The main part of the drawing machine system is the part of the line, the drawing part and the first part, and the most important part is the drawing part.

This topic is the steel cord diameter control system research, select straight into the wire drawing machine. This paper introduces the production technology of steel cord, the status quo at home and abroad and the diameter control mechanism. The research object is a drawing system composed of eight drawing machines, and the take-up part of this study is not intended to go deep. The pull motor is controlled by the inverter. System with AC variable frequency speed control technology and PLC combined with the control program, the entire drawing system at all levels rely on the difference between the speed of each drawing motor and steel cord tension to achieve synchronization and coordination, drawing motor speed by the control machine given. Outlet speed is 8 # drawing motor given speed, according to the speed chain relationship can be obtained in front of the speed of the motor 7, and set by the PLC one by one. At the same time, at the same time, as the tension sensor tuning wheel will be detected between the tension between the wire, and set the tension signal through the closed-loop PID adjustment, adjust the frequency of the corresponding inverter to change the other motor speed 7 to achieve tension Constant.

In this paper, Huichuan PLC programming software Autoshop to design ladder program to build steel wire diameter control hardware system framework; use HMI corresponding Ino Touch Editor software to prepare the man-machine interface; and in the actual hardware platform to verify part of the program, Or for simulation system testing.
