Cold forging technology is an important metal forming process, which is widely used in manufacturing various mechanical parts and structural parts. With the rapid development of the manufacturing industry, the requirements for cold forging forging are becoming higher and higher, which not only needs to meet the basic mechanical properties requirements, but also needs to have specific functional properties. Therefore, the design and manufacture of functional cold forging has become an important research direction in the field of manufacturing. This paper will discuss the manufacturing process and technical key points of functional cold forging from two aspects of design and manufacturing.
Design of functional cold forging forgings
Material selection: According to the use environment and functional requirements of the part, it is very important to choose the right material. Different materials have different mechanical properties, corrosion resistance and cost characteristics, so it needs to be considered comprehensively according to the actual situation. For example, for parts that need to withstand high loads and impacts, high-strength, high-toughness alloy steel or titanium alloys can be selected as materials.
Structure design: Structure design is an important part of cold forging forging manufacturing process. Through reasonable structural design, the functional performance requirements of parts can be realized, and the forming efficiency and forming quality of parts can be improved. For example, for parts that need to achieve a specific motion trajectory, it can be achieved by designing a suitable boss, groove and other structures.
Precision control: Precision control is the key in the manufacturing process of functional cold forging forgings. By controlling the dimensional accuracy, shape accuracy and position accuracy of the parts, it can be ensured that the parts can accurately achieve the predetermined functions during use. Therefore, in the design process, it is necessary to fully consider the accuracy requirements of the parts, and develop the corresponding manufacturing process and control measures.

Manufacturing process development: According to the design requirements of the parts, it is very important to develop the corresponding manufacturing process. The manufacturing process includes mold design, billet preparation, forming process, heat treatment process, etc. In the development of the manufacturing process, it is necessary to fully consider the characteristics of the material, the structural characteristics of the parts and the accuracy requirements and other factors to ensure that the manufactured parts can meet the design requirements.
Forming process optimization: Forming process is the core link in cold forging forging manufacturing process. By optimizing the forming process parameters, such as forming pressure, speed, lubrication, etc., the flow and deformation behavior of metal can be controlled, and the forming quality and efficiency of parts can be improved. In addition, advanced forming technology can also be used, such as multi-station forming, composite forming, etc., to further improve the forming accuracy and efficiency of parts.
Quality inspection and control: Quality inspection and control is an important part of the manufacturing process of functional cold forging forging. By using advanced quality testing technology and equipment, such as ultrasonic testing, magnetic particle testing, etc., the internal quality and surface quality of parts can be comprehensively tested and evaluated. At the same time, it can also establish a perfect quality control system and quality traceability system to ensure the quality of parts is stable and reliable.
The design and manufacture of functional cold forging is a complex and important task. Through reasonable material selection, structural design and precision control, as well as optimized manufacturing process and forming process, cold forging forging can be produced to meet the specific functional performance requirements. However, with the rapid development of the manufacturing industry and the continuous innovation of technology, the manufacturing of functional cold forging forgings has also put forward higher requirements and challenges. Therefore, in the future, we need to continue to study new materials, new processes and new technologies, promote the continuous improvement of the manufacturing level and technical content of functional cold forging forgings, and make greater contributions to the high-quality development of the manufacturing industry.
