Finally, the development prospect of the stretch forming process of aluminum alloy forgings is summarized.
As a lightweight, high-strength structural material, aluminum alloy forgings are widely used in aviation, aerospace, automotive, energy and other fields. The stretch forming process is an important link in the manufacturing process of aluminum alloy forgings, which is of great significance for improving product quality and reducing cost. Therefore, in-depth research on the tensile forming process of aluminum alloy forgings is of great significance to promote the development of related industries.
Stretch forming process is a processing method to obtain the desired shape and size by applying tension on aluminum alloy forgings to cause plastic deformation. During the tensile process, the grain structure of aluminum alloy forgings changes and the mechanical properties are improved. At the same time, the defects such as cracks and deformation can be effectively avoided by reasonably controlling the drawing process parameters.
The process steps of tensile forming of aluminum alloy forgings mainly include: blank preparation, heating, stretching, cooling and follow-up treatment. In these steps, the key technologies include the selection and pretreatment of billet, the control of drawing temperature and speed, and the selection of lubricant. Mastering these key technologies plays an important role in improving product quality and production efficiency.
The process parameters in the process of tensile forming, such as tensile temperature, speed and lubrication conditions, will affect the mechanical properties, microstructure and surface quality of aluminum alloy forgings. By adjusting these parameters reasonably, the performance of aluminum alloy forgings can be optimized. At the same time, it is also necessary to pay attention to avoid product defects caused by some poor process parameters.
In the process of tensile forming of aluminum alloy forgings, the common defects include cracks, rough surface and excessive size difference. The occurrence of these defects is closely related to the selection of process parameters, equipment accuracy, operation skills and other factors. In order to solve these problems, it is necessary to start from the source, optimize the process design, improve the accuracy of equipment, improve the operation skills of employees, and introduce advanced technical means such as non-destructive testing to achieve effective prevention and control of defects.
With the progress of science and technology and the development of manufacturing industry, the tensile forming process of aluminum alloy forgings will usher in a greater space for development. The future development direction includes: first, to further optimize the stretch forming process, improve product quality and production efficiency; The second is to strengthen the research and application of new processes and new technologies to promote the innovative development of aluminum alloy forging manufacturing industry; The third is to strengthen the application of intelligent and automated technology, improve the intelligent level of the tensile forming process of aluminum alloy forgings, and achieve green, efficient and intelligent production.
The stretch forming process of aluminum alloy forgings is of great significance to improve product quality and production efficiency. Through in-depth study of the basic principles of the tensile forming process, master the key technology and process parameters on the performance of the law, identify and solve common defects, combined with the development trend of the industry, we can further improve the technical level of aluminum alloy forgings tensile forming process, to provide strong support for the development of related industries.
