The performance of a motorcycle largely depends on the performance of its components, and the performance of the forgings in these components is closely related to the forging process. Therefore, in the field of motorcycle manufacturing, it is very important to study the influence of forging process on the structure and performance of forgings.
First, the impact of forging process on forging performance
Deformation temperature: Different forging temperatures will affect the grain size and shape of the forgings, and then affect the mechanical properties, microstructure and corrosion resistance of the forgings. In general, the right forging temperature is conducive to grain boundary slip during plastic deformation, and too high or too low forging temperature will adversely affect the performance of the forging.
Hammering energy: Hammering energy is directly related to the generation of internal fractures and defects in the forging, which affects its performance. High energy hammering is beneficial to uniform deformation, fine grain and eliminate defects, thus improving the mechanical properties and formability of forgings.
Heat treatment and cooling rate: Different heat treatment processes and cooling rates will produce different organizational structures, which will affect the mechanical properties, microstructure and corrosion resistance of forgings. For example, rapid cooling can obtain finer grains and a more uniform organizational structure, which improves the strength and toughness of forgings.
- Experimental design
When conducting experiments, common motorcycle forging materials, such as 6061 aluminum alloy and 40Cr steel, should be selected. Then, by adjusting the parameters of hammering energy, deformation temperature and heat treatment process, experiments were carried out to record and compare the differences in the structure, mechanical properties and corrosion resistance of the forging under different conditions.
- Experimental results and analysis
According to the above experimental design, the influence of forging process on the structure and performance of motorcycle forgings can be obtained. For example, when the hammering energy is 400J and the deformation temperature is 450℃, the tensile strength, yield strength and elongation of 6061 aluminum alloy forgings reach the optimal value, which may be because the temperature and energy are conducive to the change and formation of the internal organization of the forgings. For example, after water quenching, the hardness and strength of 40Cr steel forgings are significantly increased, but the toughness is slightly decreased.
Iv. Conclusion
Through the experimental study, we can draw the conclusion that the forging process has an important effect on the structure and mechanical properties of motorcycle forgings. Therefore, in the manufacturing and production of motorcycle forgings, it is necessary to scientifically adjust and optimize the forging process to obtain the best forging composition organization, and ultimately obtain better performance and quality.
