【摘要】:隨著工業(yè)技術的快速發(fā)展,人們嘗試著用不同的方法來改進、完善各式破碎機,以提升機械設備的經濟性、高效性、耐久性。針對PLM1500I液壓圓錐破碎機中動錐襯板容易產生磨損進而導致壽命不足的問題,本課題以動錐襯板為研究對象,建立了三維立體模型并進行了相關研究與分析,給出了優(yōu)化方案和驗證結果,使得動錐襯板的使用壽命得到了顯著提高。因此,關于動錐襯板的研究具有重要的意義和實際應用價值。本文的研究內容如下:(1)分析了國內外關于圓錐破碎機技術的發(fā)展現(xiàn)狀、方法和相關理論。(2)研究了PLM1500I型圓錐破碎機的結構組成及其工作原理;分析了礦石碎料在破碎機型腔內的三種運動方式;探討了圓錐破碎機破碎型腔形的分層破碎特性;剖析了圓錐破碎機運動學特性與破碎型腔內物料碎塊的運動特性對PLM1500I型圓錐破碎機工作性能的影響。(3)建立了動錐襯板的三維立體模型,采用ANSYS軟件對其進行了靜力學分析、模態(tài)分析和疲勞壽命分析,得到動錐襯板的原始參數(shù);在此基礎上,進一步對三維立體模型進行了優(yōu)化設計,分別是將原有光滑型外表改為波紋型以及增加動錐襯板的厚度,對兩種優(yōu)化方案下的動錐襯板進行靜力學分析和疲勞壽命分析。對比三種設計方案下的分析結果,得到改進后的動錐襯板使用壽命有了顯著的提高,表明兩種優(yōu)化設計均具有可行性。(4)比對了普通高錳鋼、含鉻高錳鋼、CrMoVTiRe高錳鋼和超高錳鋼的組成成分和力學性能,分析得出CrMoVTiRe高錳鋼和超高錳鋼較現(xiàn)有普通高錳鋼和含鉻高錳鋼材質更具有耐磨性,可以被考慮作為動錐襯板的制作材料,為今后襯板材質的改進提供了新的思路。
[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.
