With the development of modern industry, the demand for complex forgings is increasing day by day. As an important metal forming method, hot forging plays an important role in the production of complex forgings. This paper will introduce the characteristics of hot forging technology, and discuss its application and advantages in complex forging production.
Hot forging technology is a forming method in which the metal is heated to a certain temperature by applying pressure or impact force to produce plastic deformation of the metal, so as to obtain the required shape and performance. Hot forging technology has the following characteristics:
Plasticity enhancement: The plasticity of the metal at high temperature increases, and the deformation ability improves, which is conducive to the forging of complex shapes.
Internal structure improvement: During the hot forging process, the grain structure of the metal is improved, which improves the mechanical properties of the forgings.
Cost effective: Hot forging technology can produce mass forgings, achieve large-scale production and reduce unit costs.
Application of hot forging technology in complex forging production
Aerospace field: The aerospace field has extremely high requirements for material performance, and hot forging technology can produce forgings with complex shapes and high performance, such as engine blades and turbine disks.
Automotive industry: There are many complex shapes of forgings in automotive parts, such as crankshafts, connecting rods, etc. Hot forging technology can meet the high precision, high strength and high durability requirements of these parts.
Energy field: Oil, natural gas and other energy fields require a large number of valves, flanges and other complex forgings. Hot forging technology can produce these forgings efficiently and ensure their ability to withstand harsh conditions such as high pressure and high temperature.
Advantages of hot forging technology in complex forging production
High forming accuracy: Hot forging technology can obtain high precision forging shape and size, to meet the accuracy requirements of complex forging.
High production efficiency: hot forging process can achieve automatic and continuous production, improve production efficiency, shorten product development cycle.
High material utilization rate: Through reasonable design of hot forging process and mold, material waste can be reduced and material utilization can be improved.
With the development of science and technology and industry, hot forging technology will play a greater role in the production of complex forgings. In the future, hot forging technology will pay more attention to the research and application of process optimization, numerical simulation and intelligent manufacturing, so as to further improve the production efficiency and quality level of complex forgings and meet the ever-upgrading market demand. At the same time, with the enhancement of environmental awareness, green and low-carbon hot forging technology will also become an important development direction in the future.
