Numerical Simulation on Drawing Deep of Cylindrical Pieces Based on Dynaform

Abstract:

Abstract: The design and manufacture of mold often rely on the experience of the designers, which led to the fact that the mold needs to be repeatedly debugged and corrected. Numerical simulation technology enables the simulation of the forming process of sheet metal and prediction of defects in design, thus to improve labor efficiency, save time and reduce costs. In this paper, the software Dynaform is used as a platform and a three-dimensional model is built to numerical simulate and analyze the drawing deep of a typical thin-walled cylindrical piece.Orthogonal experimentis adopted to analyze the impact of BHF, punching speed and punch-die gap on forming quality of the drawing pieces. With minimum thickness and wrinkling as indicators, the impact of various factors is analyzed and a set of optimum parameters is found out that is, BHF is 20kN, punching speed is 2000mm / s and punch-die gap is 0.9mm.
