【摘要】：钢卷的打捆包装是热连轧钢板产品生产中非常重要的一道工序,良好的打捆包装对于确保钢卷的包装质量、安全运输以及储存等具有重要的实用价值。但热轧板卷打包机种类繁多、机构复杂,机构及结构的复杂性造成了国内钢铁企业使用的钢卷打包机多为国外进口,同时暴露出国内钢卷打包机的理论研究、材料、设计、制造等方面的不足,导致钢卷打包机的寿命及可靠性普遍低于国外。因此,课题针对热轧板卷打包机机头中的主要部件进行理论研究具有较高的实用价值和理论价值。本文首先用三维建模软件SolidWorks建立热轧板卷打包机机头中主要部件(咬扣机构、连杆机构、钢带驱动机构、导带门机构等)的模型,并对其进行结构及功能的分析。利用SolidWorks Motion对热轧板卷打包机机头的咬扣及驱动连杆机构进行运动仿真分析,进行了速度及加速度分析,分析了机构的惯性特性。通过将咬扣机构和连杆机构简化成平面图形,运用理论力学的经典理论计算了咬扣机构的最大剪切力,为有限元的载荷确定提供了可靠的数据。文中以SolidWorks Simulation软件为研究工具,以有限元法为研究手段,对热轧板卷打包机机头中的咬爪及连杆装配体进行仿真模拟研究,计算了在最大载荷下咬爪及连杆装配体中各个部件的应力及变形情况,最后利用疲劳强度理论对销轴进行安全系数及疲劳寿命的计算,并对其结构进行改进,提高了易损件销轴的使用周期。本文所做工作对热轧板卷打包机国外技术的消化吸收提供了理论帮助,为此类钢卷打包机设计及研发提供了理论参考。
[Abstract]:The packing of steel coils is a very important process in the production of hot rolled steel sheet. Good packing can ensure the packing quality of steel coils. Safe transportation and storage are of great practical value. However, there are many kinds of hot rolled coil baling machines, such as complicated mechanism, complicated structure and so on. As a result of the complexity of the mechanism and structure, the domestic iron and steel enterprises mostly import the packing machines used by domestic iron and steel enterprises. At the same time, the shortage of theoretical research, material, design and manufacture of the domestic steel coil baling machine is exposed, which leads to the lower life and reliability of the steel coil baler than that of the foreign countries. It is of high practical and theoretical value to study the main components of hot rolled sheet coiling baling machine. Firstly, the main components (bite mechanism) in the head of hot rolled sheet coiling packing machine are established by using 3D modeling software SolidWorks. The model of connecting rod mechanism, steel belt driving mechanism, guide band door mechanism and so on) is analyzed, and its structure and function are analyzed. The kinematic simulation analysis of the head bite and driving linkage mechanism of hot-rolled sheet winding machine is carried out by using SolidWorks Motion. The velocity and acceleration are analyzed, and the inertia characteristics of the mechanism are analyzed. By simplifying the bite mechanism and the linkage mechanism into plane figure, the maximum shear force of the bite mechanism is calculated by using the classical theory of theoretical mechanics. In this paper, the SolidWorks Simulation software is used as the research tool, the finite element method is used as the research means, the claw bite and the connecting rod assembly in the head of the hot rolled sheet winding machine are simulated and studied. In this paper, the stress and deformation of various parts in the jaw and connecting rod assembly body under the maximum load are calculated. Finally, the safety factor and fatigue life of the pin shaft are calculated by using the fatigue strength theory, and the structure of the pin shaft is improved. The work done in this paper has provided theoretical help for the digestion and absorption of foreign technology of hot rolled sheet coil baler and provided a theoretical reference for the design and development of this kind of steel packing machine.
