With the advancement of agricultural modernization, agricultural machinery and equipment are playing an increasingly important role in farmland operations. As the key parts of agricultural machinery, the research of wear resistance and wear mechanism of copper forgings is of great significance to improve the reliability and production efficiency of agricultural machinery. The application background, wear resistance evaluation, wear mechanism analysis and improvement methods are discussed in this paper.
I. Introduction
As an indispensable part of agricultural machinery, copper forgings bear great mechanical load and friction. Therefore, it is particularly important to study its wear resistance and wear mechanism. Only by fully understanding its wear-resistant characteristics and optimizing the design and improving the manufacturing process, can the long-term stable operation of agricultural machinery and equipment be achieved.
Second, the application background and importance of agricultural machinery copper forgings
Agricultural machinery copper forgings are widely used in tractors, harvesters, farming machinery and other agricultural machinery equipment. As a connection and support component, agricultural copper forgings directly withstand the force from the ground, working tools and other parts, so its wear characteristics determine the reliability and life of the entire agricultural equipment.
- Evaluation method of wear resistance
In order to evaluate the wear resistance of agricultural copper forgings, it is necessary to adopt a series of test methods and evaluation indexes. It includes friction coefficient test, wear amount test, surface hardness test and so on. These test methods can simulate the wear conditions under different working conditions, so as to fully understand the wear resistance of agricultural copper forgings. - Wear mechanism analysis
The main wear mechanisms to which agricultural copper forgings may be subjected include surface wear and stripping. Surface wear refers to the wear phenomenon caused by direct friction between copper forgings of agricultural machinery and other components, such as surface wear particles, wear marks and scratches. Stripping refers to the separation of the surface particles or layers of agricultural copper forgings from the substrate.
In field operations, agricultural machinery copper forgings often encounter severe working conditions, such as dust, sand and wet fields. These environmental factors will accelerate the wear of copper forgings of agricultural machinery, resulting in shortened equipment life. Therefore, the key to improve the wear resistance of agricultural copper forgings is to study the wear mechanism and improve the wear mechanism.
- Improvement methods and suggestions
In order to improve the wear resistance of agricultural copper forgings, we should start from the aspects of material selection, surface treatment, structural design and lubrication maintenance: - Material selection: According to the actual working conditions and requirements, choose copper alloy materials with good wear resistance, such as hardened copper alloy. Reasonable material selection can effectively extend the service life of copper forgings of agricultural machinery.
- Surface treatment: Through surface coating, gas carburizing and other ways to improve the surface hardness and wear resistance of agricultural copper forgings. Choosing suitable surface treatment can effectively reduce the wear of copper forgings of agricultural machinery.
- Structural design: Reasonable design of the shape, size and structure of agricultural machinery copper forgings to reduce contact stress and reduce the risk of wear and fatigue damage. The wear resistance of copper forgings of agricultural machinery can be improved by optimizing the structure design.
- Lubrication maintenance: Regular lubrication and maintenance of agricultural copper forgings to reduce friction and wear. Appropriate lubricants and maintenance methods can reduce the wear and tear of agricultural copper forgings and extend their service life.
Vi. Conclusion
The wear resistance characteristics and wear mechanism of agricultural copper forgings are of great significance to improve the reliability and efficiency of agricultural machinery. Through in-depth analysis of its wear mechanism, and through reasonable material selection, surface treatment, structural design and lubrication maintenance measures, the wear resistance of agricultural machinery copper forgings can be effectively improved, and its service life can be extended.
In the process of agricultural modernization, the stable operation of agricultural machinery and equipment is the basis of farm operations, and the wear resistance of copper forgings of agricultural machinery is a crucial part. Therefore, further research on the wear-resistant characteristics and wear mechanism of agricultural copper forgings and corresponding improvement measures are of positive significance for improving the efficiency and reliability of agricultural machinery and equipment and promoting agricultural modernization.
