Study on a New Technological Scheme for Cold Press Forging Forming of Step Holes in Thick Sheet Metal
An new technological scheme for a two-step cold press forging of step holes in a thick metal sheet was proposed . Finite element analysis on the two-step process is carried out by using DEFORM-3D. Velocity shade contours are obtained. The study shows that the technique can form step holes in thick sheet metal and increase their strength, According to the numerical simulation’s process parameter, an experimental die is designed, the FEA results are in good agreement with the experimental data.
