Warm forging technology is an important metal forming process, which is widely used in the manufacture of various forgings. However, in the actual production process, the toughness of warm forging is often affected by a variety of factors, resulting in unstable product quality. Therefore, this paper aims to explore the main factors affecting the toughness of warm forging parts, and put forward corresponding improvement measures to improve the quality and performance of products.
The main factors affecting the toughness of warm forging parts
Material properties: The chemical composition, crystal structure and mechanical properties of the material will affect the toughness of the warm forging. For example, if there are a lot of inclusions, pores and other defects in the material, it will reduce the toughness of the forging.
Forging temperature: Forging temperature is an important factor affecting the toughness of warm forging forgings. If the forging temperature is too high, the grain growth and mechanical properties of the material will decrease. The forging temperature is too low, it will make the material deformation difficult, easy to crack.
Deformation speed: Deformation speed will also affect the toughness of warm forging. If the deformation speed is too fast, the stress distribution inside the material will be uneven, and it is easy to crack; If the deformation rate is too slow, the grain size of the material will grow and the toughness will be reduced.
Mold design: The design of the mold will also affect the toughness of the warm forging. If the mold design is not reasonable, it will lead to uneven stress distribution in the forging process, and it is easy to produce cracks.
Cooling method: Cooling method will also affect the toughness of warm forging forging. If the cooling speed is too fast, residual stress will occur inside the material, reducing toughness; If the cooling rate is too slow, the material will be coarse and the mechanical properties will be reduced.
Improving measures to improve toughness of warm forging parts
Optimize material selection: Select high-quality materials and carry out strict chemical composition and mechanical properties testing to ensure that the material meets the production requirements.
Forging temperature control: According to the nature of the material and forging requirements, develop a reasonable forging temperature range, and strict temperature control.
Adjust the deformation speed: according to the nature of the material and forging requirements, adjust the deformation speed to ensure that the material is subjected to uniform stress distribution during the forming process.
Optimization of mold design: The use of advanced mold design technology and simulation analysis means to optimize the design of the mold to ensure that the forging is subjected to uniform stress distribution during the forming process.
Improve the cooling method: adopt the appropriate cooling method and cooling speed to ensure that the material will not produce residual stress and coarse structure during the cooling process.
Introduction of heat treatment process: Through the introduction of appropriate heat treatment process, such as quenching, tempering, etc., can improve the structure and mechanical properties of the material, improve the toughness of warm forging forgings.
Strengthen quality inspection: Establish a sound quality inspection system, and carry out comprehensive quality inspection and control on the output of warm forging forgings to ensure that the product quality meets the requirements.
This paper probes into the main factors affecting the toughness of warm forging parts, and puts forward the corresponding improvement measures. By optimizing the selection of materials, controlling the forging temperature, adjusting the deformation speed, optimizing the mold design, improving the cooling method, introducing the heat treatment process and strengthening the quality inspection, the toughness of the warm forging forging can be effectively improved, and the quality and performance of the product can be improved. However, with the continuous progress of science and technology and the constant change of market demand, the quality and performance requirements of warm forging forging will continue to improve. Therefore, we need to continue to deeply study the factors affecting the toughness of warm forging forgings and their improvement measures to meet the constant changes in the market and the continuous improvement of customer demand.
