【摘要】：随着经济的增长，钢铁企业在国民经济中起到的作用越来越大，钢铁冶金设备的研究也逐渐深入，但是我国冶金设备研究起步较晚，与国外存在一定差距。线材打捆机是钢铁企业高速线材生产线特有的重要设备。送线机构作为线材打捆机的重要组成部分，它由送线轮、驱动盘、导向压轮、液压缸以及液压马达等几部分组成。送线性能的好坏决定着打捆机的生产效率，因而对送线机构进行设计分析有着重大的现实意义。目前虽然对打捆机的研究文献较多，但对送线机构的研究较少，本课题专门针对线材打捆机的送线机构进行虚拟设计与性能强度分析，具有一定的应用价值和创新性。基于森德斯全自动打捆机送线机构的工作原理，自行设计开发了一套送线机构，通过理论计算，对送线机构中的液压缸、液压马达和轴承等进行了设计选取。通过Solidworks对送线机构进行三维建模、装配、干涉检查，使用Motion进行运动仿真模拟。通过三维建模，装配使送线机构真实的呈现出来，，通过干涉检测课题看到装配不当或者尺寸设计不合理的地方，以便进行进一步调整。Motion进行运动仿真，可以直观的看到机构各个零部件的动作情况，通过仿真模拟获得整体各个物理量的图像，对整体进行优化设计提供依据。应用ANSYS软件对导向压轮、驱动盘、偏心轴等主要受力零部件进行应力应变分析，根据应力变形区域较大的地方，进行了理论计算，提出相应的避免措施。对设计改进送线机构主要受力零部件具有借鉴意义。送线系统作为送线机构的核心部分，应用ANSYS软件对送线机构的送线线系统进行了进一步分析，并与前面的理论计算结果进行比较，使得到结论更具说服力。最后对驱动盘的磨损及寿命进行了理论计算，并总结了提高驱动盘耐磨强度的相关措施。本课题设计开发了一套线材打捆机的送线机构，并利用Solidworks和ANSYS对其进行了虚拟设计与性能强度分析，通过与理论计算结果比较，确定了可信性。通过对驱动盘进行的理论计算，总结了提高其耐磨强度的相关措施。本课题的研究内容和研究方法，可以为其他线材打捆机的送线机构设计开发提供参考，并对现有打捆机送线机构的研究分析和改进也具有一定的借鉴价值。
[Abstract]:With the economic growth, the iron and steel enterprises play a more and more important role in the national economy, and the research of steel metallurgical equipment is gradually deepened. However, the research of metallurgical equipment in China started relatively late and has a certain gap with the foreign countries. The wire rod bundling machine is a special equipment for the high-speed wire rod production line of steel enterprises. It is an important part of the machine, which consists of a feeder wheel, a driving disc, a steering wheel, a hydraulic cylinder and a hydraulic motor. The performance of the feeder determines the production efficiency of the baling machine. Therefore, it is of great practical significance to the design and analysis of the feeder mechanism. Less research, this topic specifically aims at the virtual design and performance analysis of wire feeding mechanism of wire baler, which has certain application value and innovation.
Based on the working principle of the feeder mechanism of the full automatic baling machine, a set of wire feeding mechanism is designed and developed by ourselves. Through theoretical calculation, the hydraulic cylinder, hydraulic motor and bearing in the feeder are designed and selected.
Through Solidworks, three dimensional modeling, assembly, interference inspection and motion simulation are carried out by Motion. Through 3D modeling, the assembly makes the feeder mechanism truly present, and the improper assembly or unreasonable size of the size design is seen through the interference test in order to further adjust the motion imitation of the.Motion. It is true that the movements of the parts of the mechanism can be seen intuitively, and the images of the whole physical quantities can be obtained through simulation and simulation, and the basis for the optimization of the whole design is provided.
The ANSYS software is used to analyze the stress and strain of the main force parts, such as the steering wheel, the driving disc and the eccentric shaft. According to the larger area of the stress and deformation area, the theoretical calculation is carried out and the corresponding measures are put forward. It is of reference for the design and improvement of the main force parts of the feeder mechanism.
As the core part of the wire feeding mechanism, the transmission line system is used to further analyze the line transmission line system of the feeder mechanism by ANSYS software, and compare with the previous theoretical calculation results, making the conclusion more convincing.
Finally, the wear and life of the driving plate are theoretically calculated, and the relevant measures to improve the wear resistance of the driving plate are summarized.
This subject designs and develops a set of wire feeding mechanism for wire rod bundling machine, and uses Solidworks and ANSYS to carry out the virtual design and performance strength analysis. By comparing with the theoretical calculation results, it determines the credibility. Through the theoretical calculation of the driving disk, the relevant measures to improve the wear resistance are summarized. The capacity and research method can provide reference for the design and development of wire feeding mechanism of other wire rod bundling machines, and also have some reference value for the research analysis and improvement of the existing baling machine transmission mechanism.
