Advantages of cold forging technology in complex shape forging production

With the continuous development of the manufacturing industry, the demand for forgings is also increasing, especially in the automotive, aerospace, energy and other fields, the shape and performance requirements of forgings are also getting higher and higher. Although the traditional hot forging technology is mature, it is often limited in the production of complex forgings. The emergence of cold forging technology provides a new solution for the production of complex forgings. This paper will discuss the advantages of cold forging technology in complex shape forging production from many angles.

Cold forging technology is a plastic deformation process of metal at room temperature, which has the characteristics of high precision, high efficiency and high performance. Compared with hot forging technology, cold forging technology has better dimensional accuracy and surface quality, so it has significant advantages in the production of complex shape forgings.

Cold forging technology can achieve high precision forging by precisely controlling the shape and size of the die. For forgings with complex shapes, cold forging technology can achieve the precise flow and filling of metal in the mold through the design and optimization of the multi-station mold, so as to obtain the required complex shape. In addition, cold forging technology can further optimize the forming effect by adjusting the process parameters such as pressing speed, pressing force and holding time.

Cold forging technology has the characteristics of high efficiency production. Because the cold forging process is carried out at room temperature, it does not require heating and cooling as hot forging does, saving energy and time. In addition, the cold forging process enables automated production, enabling efficient and continuous production processes with robots and automated equipment. This not only improves production efficiency, but also reduces production costs.

Cold forging process can improve the internal structure and mechanical properties of metals. In the process of cold forging, the metal underwent severe plastic deformation, its grain was refined, and the internal structure became more dense. This refined and densified structure enables cold forging forgings to have excellent mechanical properties, such as high strength, high toughness and good wear resistance. These excellent mechanical properties enable cold forging forgings to perform better under complex stresses and harsh environments.

Cold forging technology has been widely used in many fields. In the automotive industry, cold forging technology is used to manufacture core components such as engine connecting rods, crankshafts and drive shafts, which need to withstand high-speed rotation and impact loads, and therefore have extremely high requirements for strength and wear resistance. In the aerospace sector, cold forging technology is used to manufacture aircraft engines, transmission systems, landing gear and other key parts, which need to withstand high temperatures, high pressure and strong corrosion and other harsh environments, so the performance of parts is extremely high. In addition, in energy, petrochemical and other fields, cold forging technology is also widely used in the manufacture of high pressure valves, flanges, pipelines and other key equipment.

Compared to traditional hot forging technology, cold forging technology has a more environmentally sustainable production process. Since heating and cooling are not required, the cold forging process reduces energy consumption and exhaust emissions. In addition, the cold forging process can also realize the recycling of materials, reduce production costs and improve resource utilization. This is in line with the current trend of green development of manufacturing.

In summary, cold forging technology has significant advantages in the production of complex forgings, including high-precision forming, high-efficiency production, excellent mechanical properties, a wide range of applications and environmentally sustainable production processes. With the continuous progress and innovation of science and technology, it is believed that cold forging technology will be applied and developed in more fields in the future.
