[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.
