With the development of construction machinery, the requirements for construction machinery parts are also getting higher and higher, especially in terms of improving strength and lightweight. Magnesium forgings, as an important form of construction machinery parts, have the characteristics of light weight and high strength, and can be further improved by the following methods to achieve lightweight:
- Material selection: The selection of high-strength magnesium alloy materials is the basis for improving the strength of magnesium forgings. Commonly used high strength magnesium alloys include AZ series and ZK series. These alloys can obtain higher strength and mechanical properties through reasonable element allocation and heat treatment process.
- Accurate design: In the design of magnesium forgings, it is necessary to use accurate design methods according to the actual stress distribution and working conditions. The strength and stiffness of the parts can be improved by optimizing the structural form, reducing the stress concentration and increasing the stress area.
- Process improvement: In the forging and subsequent heat treatment process, appropriate process parameters and technical measures should be taken to improve the mechanical properties of magnesium forgings. For example, through a moderate amount of deformation and forging temperature, finer grains and uniform organizational structure can be obtained to improve the strength of the material.
- Surface treatment: Surface treatment of magnesium forgings, such as anodizing, electroplating or spraying, can further improve its corrosion resistance and surface hardness. At the same time, the surface treatment can also improve the appearance quality of the parts, improve the overall strength and lightweight effect.
- Structural optimization: By optimizing the structure of magnesium forgings, the weight of parts can be reduced and their strength improved. For example, the design ideas such as hollow structure, thin-wall structure or laminated structure can achieve light quality and ensure sufficient strength.
In SUMMARY:
To improve the strength and lightweight of magnesium forgings of construction machinery is a problem that considers many factors such as material, design and process. Through reasonable material selection, accurate design, optimized process and structural optimization, the strength of magnesium forgings can be continuously improved and better lightweight results can be achieved. This not only helps to improve the overall performance and efficiency of construction machinery, but also reduces the load and fuel consumption of equipment, contributing to the sustainable development of the construction machinery industry.
