【摘要】：珍珠岩吸音板作为一种新型建材,具有吸声、防火、保温等多种功能,具有日益广阔的市场空间。但目前吸音板的生产方式多为半自动化生产,生产效率低下、成本高、产品质量难以保证,为了满足日益增长的珍珠岩吸音板市场需求,在国内现有珍珠岩吸音板加工设备的基础上进行自动化生产线的设计与改进,提供一条能够稳定运行、生产效率较高的珍珠岩吸音板自动化生产线具有重大的意义。为此,本论文设计研究了一种吸音板带式自动化生产线,其具有生产效率高、设备稳定性强、成品质量高的特点。本论文首先依据企业对珍珠岩吸音板生产线的生产要求,分析了现有的平推上下循环式吸音板生产线、圆盘回转式吸音板生产线以及无模具生产线的工作方式,着重针对无模具生产线方案的优势与不足,结合对珍珠岩物料冲压理论分析,拟定了吸音板带式生产线的总体设计方案,确定了主线的基本结构形式。其次,论文分别针对带式生产线主线中的上层输送链、下层输送带、液压冲压机等主体结构及其配套装置进行了理论分析与结构设计,完成了相关参数的计算,并借助SolidWorks三维设计软件完成了主线各零部件的三维建模以及主线整机的三维装配,验证结构设计和各部分之间的配合关系是否合理,也为后面的仿真分析提供了模型支持。最后,结合前面所建立的主线机构的三维模型,运用ANSYS Workbench软件对吸音板带式生产线主线的下层输送带驱动滚筒进行动力学仿真,对上层输送链做了接触分析。通过对驱动滚筒的模态分析得出了其前6阶固有频率和相应的振型等,并以驱动滚筒两个参数为变量对其进行了动力学优化设计,有效改进了驱动滚筒的动力学特性,使其在工况下的抗振性显著增强;对上层输送链的接触分析也验证了上层输送链设计的可靠性,为吸音板生产线的设计和方案的实际应用提供了有力的理论依据。
[Abstract]:As a new type of building materials, perlite sound-absorbing board has many functions, such as sound absorption, fire prevention, heat preservation and so on.However, at present, most of the production methods of sound-absorbing boards are semi-automatic. The production efficiency is low, the cost is high, and the quality of the products is difficult to guarantee. In order to meet the increasing market demand of perlite sound-absorbing boards,It is of great significance to design and improve the automatic production line on the basis of the existing perlite sound-absorbing plate processing equipment in China, and to provide an automatic production line of perlite sound-absorbing plate with stable operation and high production efficiency.Therefore, this paper designs and researches a kind of automatic production line of sound-absorbing plate and belt, which has the characteristics of high production efficiency, strong stability of equipment and high quality of finished product.Firstly, according to the production requirements of perlite sound-absorbing plate production line, this paper analyzes the working methods of the existing horizontal push up-and-down circulatory sound-absorbing plate production line, the disc rotary sound-absorbing plate production line and the no-mould production line.In view of the advantages and disadvantages of the production line without mould, combined with the theoretical analysis of perlite material stamping, the overall design scheme of the sound-absorbing plate and belt production line is drawn up, and the basic structural form of the main line is determined.Secondly, the paper carries on the theoretical analysis and structural design for the main structure of the upper conveying chain, the lower conveyor belt, the hydraulic punching machine and its supporting devices in the main line of the belt production line, and completes the calculation of the related parameters.With the help of SolidWorks 3D design software, the 3D modeling of each part of the main line and the 3D assembly of the mainline machine are completed, which verifies whether the structural design and the coordination relationship between the parts are reasonable or not, and also provides the model support for the simulation analysis in the future.Finally, combined with the 3D model of the main line mechanism, the dynamic simulation of the lower conveyor belt driving drum in the main line of the sound-absorbing plate and belt production line is carried out by using ANSYS Workbench software, and the contact analysis of the upper conveying chain is made.Based on the modal analysis of the driving drum, the first 6 natural frequencies and the corresponding vibration modes are obtained, and the dynamic optimization design of the driving drum is carried out with two parameters as variables, which effectively improves the dynamic characteristics of the driving drum.The contact analysis of the upper transport chain also verifies the reliability of the design of the upper transport chain, which provides a powerful theoretical basis for the design and practical application of the sound-absorbing plate production line.
