【摘要】：随着工业技术的快速发展,人们尝试着用不同的方法来改进、完善各式破碎机,以提升机械设备的经济性、高效性、耐久性。针对PLM1500I液压圆锥破碎机中动锥衬板容易产生磨损进而导致寿命不足的问题,本课题以动锥衬板为研究对象,建立了三维立体模型并进行了相关研究与分析,给出了优化方案和验证结果,使得动锥衬板的使用寿命得到了显著提高。因此,关于动锥衬板的研究具有重要的意义和实际应用价值。本文的研究内容如下:(1)分析了国内外关于圆锥破碎机技术的发展现状、方法和相关理论。(2)研究了PLM1500I型圆锥破碎机的结构组成及其工作原理;分析了矿石碎料在破碎机型腔内的三种运动方式;探讨了圆锥破碎机破碎型腔形的分层破碎特性;剖析了圆锥破碎机运动学特性与破碎型腔内物料碎块的运动特性对PLM1500I型圆锥破碎机工作性能的影响。(3)建立了动锥衬板的三维立体模型,采用ANSYS软件对其进行了静力学分析、模态分析和疲劳寿命分析,得到动锥衬板的原始参数;在此基础上,进一步对三维立体模型进行了优化设计,分别是将原有光滑型外表改为波纹型以及增加动锥衬板的厚度,对两种优化方案下的动锥衬板进行静力学分析和疲劳寿命分析。对比三种设计方案下的分析结果,得到改进后的动锥衬板使用寿命有了显著的提高,表明两种优化设计均具有可行性。(4)比对了普通高锰钢、含铬高锰钢、CrMoVTiRe高锰钢和超高锰钢的组成成分和力学性能,分析得出CrMoVTiRe高锰钢和超高锰钢较现有普通高锰钢和含铬高锰钢材质更具有耐磨性,可以被考虑作为动锥衬板的制作材料,为今后衬板材质的改进提供了新的思路。
[Abstract]:With the rapid development of industrial technology, people try to use different methods to improve the various crusher, in order to improve the economy, efficiency and durability of mechanical equipment. In view of the problem that the moving cone lining in PLM1500I hydraulic cone crusher is easy to wear and lead to insufficient life, this paper takes the moving cone liner as the research object, establishes the three-dimensional model and carries on the related research and analysis. The optimization scheme and the verification result are given, and the service life of the moving cone liner is greatly improved. Therefore, the research of moving cone lining plate has important significance and practical application value. The research contents of this paper are as follows: (1) the development status, methods and related theories of cone crusher at home and abroad are analyzed. (2) the structure composition and working principle of PLM1500I cone crusher are studied. This paper analyzes three kinds of moving modes of ore particles in the crusher cavity, and discusses the stratified crushing characteristics of the conical crusher cavity shape. The effect of kinematics characteristics of cone crusher and the movement characteristics of material in crushing cavity on the working performance of PLM1500I type cone crusher is analyzed. The three-dimensional model of moving cone lining plate is established, and the statics analysis is carried out by using ANSYS software. On the basis of modal analysis and fatigue life analysis, the original parameters of moving cone liner are obtained, and the three-dimensional model is further optimized, which is to change the original smooth surface into corrugated shape and to increase the thickness of moving cone liner. The static analysis and fatigue life analysis of the dynamic cone liner under two optimization schemes are carried out. Compared with the analysis results of the three design schemes, the service life of the improved dynamic cone lining plate has been significantly improved, which shows that the two optimized designs are feasible and compared with the common high manganese steel. The composition and mechanical properties of CrMoVTiRe high manganese steel and ultra high manganese steel are analyzed. The results show that CrMoVTiRe high manganese steel and super high manganese steel have better wear resistance than common high manganese steel and high manganese steel containing chromium. It can be considered as the manufacturing material of the moving cone liner, which provides a new idea for the improvement of the material quality of the liner in the future.
