The manufacturing process of aviation forgings is a complex process involving many links and technologies. The following is the general process flow and technical innovation of aviation forgings manufacturing. Material selection: Aviation forgings usually use alloy materials with high strength, high temperature resistance and corrosion resistance, such as titanium alloy, nickel-based alloy and aluminum alloy. With the development of material science and technology, new alloy materials continue to emerge, with better performance and adaptability, and can meet the requirements of strength, weight and durability of aviation forgings. Forging process: Aviation forgings are usually achieved by hot forging. Hot forging is the process of heating a metal material to a certain temperature, and then applying pressure to make it plastic deformation, and finally obtain the desired shape. In the manufacturing of aviation forgings, axial, circumferential and complex geometry forging processes are used to ensure high strength and accuracy of parts. Precision machining and heat treatment: Aviation forgings need to be precision machined after forging to achieve the precision and surface quality required by the design. This includes turning, milling, drilling, grinding and other processes. At the same time, aviation forgings also need to be heat treated to improve the mechanical properties and corrosion resistance of the material. Inspection and quality control: In the manufacturing process of aviation forgings, strict inspection and quality control are essential. Various non-destructive testing techniques such as ultrasonic testing, X-ray testing, magnetic particle testing, etc. are applied to the surface and internal defect detection of forgings. In addition, there are dimensional measurements, chemical composition analysis and other methods to ensure the quality and compliance of aviation forgings. Technological innovation: With the continuous development of science and technology, aviation forging manufacturing is also constantly innovating. Some of the key technological innovations include: advanced forging die design and manufacturing techniques that enable the production of more complex shapes and higher precision aviation forgings. Virtual forging technology based on computer simulation and modeling can predict the deformation and crack of forgings and guide the optimization of forging process. Progress in the field of material engineering, including the design and development of alloy materials and the improvement of surface engineering technology, has provided new possibilities for the performance improvement of aviation forgings. Advanced non-destructive testing technologies, such as laser ultrasonic testing and infrared thermal imaging, help to improve the efficiency and accuracy of the detection of internal and surface defects in forgings. To sum up, the manufacturing process and technological innovation of aviation forgings is a constantly developing field. Through continuous research and innovation, aviation forgings manufacturing will achieve higher accuracy, better performance and more reliable quality, providing support and promotion for the development of the aviation industry.
