The key technology in the manufacture of aircraft forgings

Aircraft forgings are key components in aircraft structure, whose quality and performance directly affect the safety and service life of aircraft. In the manufacturing process of aircraft forgings, there are some key technologies that play a crucial role in the quality and performance of the forgings. This paper will introduce the key technologies in the manufacturing process of aircraft forgings from the following aspects.

First, forging technology

Forging technology is one of the core technologies in the manufacturing process of aircraft forgings. Through forging technology, raw materials can be heated to the appropriate temperature, and then deformed on the forging equipment to obtain the desired shape and size. In the forging process, parameters such as forging temperature, deformation amount and deformation speed need to be reasonably controlled to ensure the quality and performance of the forging. In addition, forging technology also includes a variety of advanced forging methods such as multi-directional forging, isothermal forging, precision die forging, etc., which can be selected according to different material characteristics and product requirements.

Second, heat treatment technology

Heat treatment technology is another key technology in the manufacturing process of aircraft forgings. Through heat treatment technology, the internal structure and performance of the forging can be changed to improve its strength and toughness. In the heat treatment process, it is necessary to reasonably control the parameters of heat treatment temperature, time and cooling speed to ensure the quality and performance of the forging. In addition, heat treatment technology also includes solution treatment, aging treatment, quenching and other methods, you can choose the appropriate heat treatment method according to different material characteristics and product requirements.

Third, machining technology

Machining technology is another important technology in the manufacturing process of aircraft forgings. Through machining technology, forgings can be further processed and improved to meet product requirements and shape and dimension accuracy. In the machining process, it is necessary to reasonably control the cutting speed, feed rate, cutting depth and other parameters to ensure the processing quality and efficiency. In addition, machining technology also includes CNC machining, precision grinding and other advanced processing methods, you can choose the right machining method according to different product requirements and material characteristics.

Fourth, detection technology

Inspection technology is another key technology in the manufacturing process of aircraft forgings. Through inspection technology, it is possible to carry out comprehensive quality inspection and control of forgings to ensure that they meet the relevant standards and requirements. In the testing process, it is necessary to adopt a variety of testing means and methods, including non-destructive testing, chemical composition analysis, mechanical property testing, etc., to ensure the accuracy and reliability of the test results. In addition, the detection technology also includes a variety of advanced detection methods such as automated detection and remote detection, which can improve the detection efficiency and accuracy.

The manufacturing process of aircraft forgings involves many key technologies, including forging technology, heat treatment technology, machining technology and testing technology. These technologies play an important role in different stages and links, and together ensure the quality and performance of aircraft forgings. In actual manufacturing, enterprises need to choose the appropriate process parameters and methods according to product requirements and material characteristics to ensure the quality and performance of forgings. At the same time, strengthening technology research and development and improving production efficiency are also important development directions for aircraft forging manufacturing enterprises. Only in this way can we provide a strong guarantee for the rapid development of the aviation industry.
