Computer Simulation of the Half-Tore Forming Process from a Ring Blank

Abstract:

This paper presents the theoretical foundations and methodology of the modeling process of forming a half ring alloy blank AMg5M in software product Pam-Stamp. At the following technological sizes of a half-tore: the blank radius 516.5 mm; hole’s radius R₀=480.74 mm, distance from the generating circle center to the axis of rotation R₁=714 mm, the generating circle radius R_p=93 mm, curvature radius of die R_d=16 mm, the process is stable. The results of numerical analysis of the drawing half-tore from the ring blank directed to determining the optimal process parameters are revealed. Modeling shows that the size of the holes in the blank has a significant influence on the distribution of strain along the generatrix of the stamped parts. Using the ring blank reduces the probability of wrinkling in the free areas.
