With the continuous development of the construction machinery industry and the progress of technology, the use of high-quality materials to manufacture parts has become one of the important means to improve product performance and quality. In this process, the performance optimization and design improvement of magnesium forgings of construction machinery are particularly critical. This paper will discuss this problem from the aspects of material selection, forging process design, structural design improvement, surface treatment and mold design optimization.
First of all, material selection is one of the important factors affecting the performance of parts. By choosing magnesium alloy with excellent comprehensive properties as forging material, the specific strength and specific stiffness of parts can be improved, and it has good heat conductivity and corrosion resistance. Magnesium alloy has the characteristics of light weight and high strength, which is suitable for construction machinery and other fields that need to reduce the dead weight load. Therefore, the selection of suitable magnesium alloy is of great significance.
Secondly, reasonable forging process design is also the key to ensure the performance of parts. By controlling the temperature, deformation rate and other parameters in the forging process, the grain can be refined and the uniform distribution of the structure can be achieved, so as to improve the strength and toughness of the parts. In addition, the mechanical properties of the parts can be further adjusted through subsequent heat treatment such as aging treatment and solution treatment.
In terms of structural design, it is necessary to carry out reasonable structural design improvement according to the application environment and working conditions of construction machinery. The impact resistance of the parts can be improved by increasing the local strengthening area of the parts with greater impact force. With proper rounded corner design, stress concentration and crack generation can be avoided. In addition, reasonable geometric shape and dimensional design can improve the overall stiffness and stability of the parts.
Surface treatment also plays a key role in the performance optimization of magnesium forgings in construction machinery. Surface spraying, oxidation treatment and other methods can improve the wear resistance, corrosion resistance and high temperature resistance of parts and extend the service life of parts.
Finally, mold design optimization is also closely related to the performance of the parts. Reasonable mold design and manufacturing ensure the reliability and stability of the forging process. Through advanced numerical simulation technology such as finite element analysis, it can assist the design and optimization of the mold, predict and control the stress and deformation in the forging process, and improve the quality and production efficiency of the parts.
In summary, the performance optimization and design improvement of magnesium forgings of construction machinery include material selection, forging process design, structural design improvement, surface treatment and mold design optimization. Only through the comprehensive application of these improvement measures can the construction machinery magnesium forgings have higher strength, toughness, wear resistance and corrosion resistance during use, so as to improve the performance and reliability of the product. At the same time, we should pay attention to the rational use of resources in the design process, uphold the concept of green environmental protection, and promote the sustainable development of the construction machinery industry.
