Abstract
The deep drawing process is a major sheet metal process used in various industrial fields, such as automobile, aerospace, computer and electronics, household utensils, and medical equipment industries. The earring defect is the main barrier to decreasing the formability, production cost, and time requirements. In this research, the so-called vertex bar tool (VBT), comprising a vertex bar (VB) die and vertex bar blankholder (VB blankholder), was proposed to decrease earring defects. The finite element method (FEM) was used to predict material flow direction within the designed tool to illustrate the principle of VB. The results demonstrate that the VB die and VB blankholder could reduce the flat top die's non-axisymmetric material flow characteristic and asymmetry during the deep drawing process. Furthermore, the workpiece thickness measured during the deep drawing process using the VB die and VB blankholder in a direction along the plane at 0°,45°, and 90° to the rolling direction were more uniform than those obtained by conventional die application implemented at the same angles in a direction along the plane. The VB die, and VB blankholder design proposed in this study fulfilled the hypothesized purpose. Therefore, using proper VB die and VB blankholder application, the earring defect could be decreased to 1.6 mm, denoting a decrease of approximately 55.55%.
