【摘要】：目前我國社會現(xiàn)代化和工業(yè)化進程還尚未完成，大量的鐵路、隧道、公路、水利等基本設施正在建設,還有大量的礦山正在開采，這就給液壓破碎錘提供了十分強勁的市場需求。由于液壓破碎錘是在作業(yè)環(huán)境非常惡劣的條件下進行的，因此對其各零部件的結構的設計、材料的選取以及生產加工的水平要求都非常高。通過對液壓破碎錘進行更深入的研究，搞明白液壓破碎錘的工作原理及釬桿的疲勞壽命等問題，為設計出作業(yè)安全、制造工藝簡便易行以及節(jié)省能源的液壓破碎錘提供理論依據(jù)，對提高國產液壓破碎錘的整體技術實力以及提高在全球知名品牌中的核心競爭力是非常必要的。正因如此，對液壓破碎錘的工作原理和主要零部件的研究，努力縮小國產液壓破碎錘與其他國家的核心技術差距，提升國產破碎錘的科技含量，，提高液壓破碎錘的使用性能和外部造型美觀等方面，為企業(yè)創(chuàng)造出更多的經(jīng)濟效益具有十分重要的意義。 文章闡述了國內外在液壓破碎錘理論研究方面的差異、液壓破碎錘的應用范圍、液壓破碎錘的優(yōu)缺點、目前需要改進的不足之處以及未來發(fā)展的主要趨勢。文中選用國產某型號的液壓破碎錘作為研究對象，重點做了以下三個方面的研究： 第一，對液壓破碎錘基本結構以及沖擊破碎的工作原理進行研究，詳細闡述了液壓破碎錘選型和主要零部件的作用以及失效形式等相關問題。 第二，運用Solidworks軟件對液壓破碎錘釬桿進行應力分析、疲勞分析，計算釬桿的疲勞壽命。 第三，對疲勞累積損傷的基本原理進行闡述，并基于疲勞累積損傷理論對釬桿的疲勞壽命進行估算。對以上兩個結果進行對比，驗證了Solidworks軟件對疲勞壽命估算的精確性。最后對釬桿的尺寸進行優(yōu)化設計，實現(xiàn)減輕釬桿重量的目的。該文研究方法注重理論與實際相結合，為進一步的研究提高液壓破碎錘性能打下良好的基礎。
[Abstract]:At present, the process of social modernization and industrialization in our country has not yet been completed. A large number of basic facilities such as railways, tunnels, highways and water conservancy are being built, and a large number of mines are being mined. This provides a very strong market demand for hydraulic breakers. Because the hydraulic hammer is carried out under very bad conditions of the operating environment, the hydraulic crushing hammer is carried out. The design of the structure of each component, the selection of the material and the level of production and processing are very high. Through a more thorough study of the hydraulic crushing hammer, the working principle of the hydraulic crushing hammer and the fatigue life of the rod are understood, so as to design the safety of the work, the manufacturing process is simple and easy, and the hydraulic breaking of the energy saving is saved. The broken hammer provides a theoretical basis for improving the overall technical strength of the domestic hydraulic hammer and improving the core competitiveness of the world famous brands. Because of this, the research on the working principle and main parts of the hydraulic crushing hammer is made hard to reduce the core technical gap between the domestic hydraulic crushing hammer and other countries and improve the core technology. It is of great significance to create more economic benefits for enterprises to improve the scientific and technological content of the domestic broken hammer and to improve the performance of the hydraulic hammer and the appearance of the external shape.
The paper expounds the differences between the theoretical research on hydraulic crushing hammer at home and abroad, the application range of the hydraulic crushing hammer, the advantages and disadvantages of the hydraulic crushing hammer, the deficiency and the main trend of the future development. In this paper, a hydraulic crushing hammer made in China is selected as the research object, and the following three aspects are mainly studied. :
First, the basic structure of the hydraulic crushing hammer and the working principle of the impact crushing are studied. The selection of the hydraulic crushing hammer, the function of the main parts and the failure forms are expounded in detail.
Second, stress analysis, fatigue analysis and calculation of fatigue life of drill rod are carried out by Solidworks software.
Third, the basic principle of fatigue cumulative damage is expounded, and the fatigue life of the drill rod is estimated based on the fatigue cumulative damage theory. The above two results are compared to verify the accuracy of Solidworks software for fatigue life estimation. Finally, the size of the brazing rod is optimized to reduce the weight of the drill rod. The research method of this paper focuses on the combination of theory and practice, laying a good foundation for further research to improve the performance of hydraulic breaking hammer.
