Abstract：

In the early stage of process design, there are many kinds of forming process schemes for precision forgings. In order to determine the most suitable process, for automobile flange body part, the thermo-mechanical coupling numerical simulation was carried out by CAE analysis software Deform-3D. Due to the complex structure of part, it could not be formed at one time by analysis, and combined with the plastic forming technology, three forming process schemes were preliminarily determined. Firstly, the forming quality of forgings and the service life of mold were comprehensively analyzed and compared. Then, the stress value, strain value, load value of mold and damage value of part were optimized by established mathematical evaluation model. The results show that scheme 3 has advantages in forgings quality, service life of mold and other aspects. Finally, the production test was carried out by using the forming process of scheme 3, and the flange body parts were fully formed with good shape and without defects. Thus, through the organic combination of finite element technology and mathematical model, the best process could be obtained efficiently, and the cost of die test is greatly reduced.
