Study About Effects of Oblique Angle of Die Surface to the Product Quality in the Deep Drawing

Abstract

Deep drawing is one of the special methods for the sheet metal forming in the pressure processing field. This method is applied to manufacture the mechanical products with the deep and complex shapes. The influences of oblique angle of die surface to the product quality of the metallic forming are diccussed. This study uses the Abaqus software to simulate for four cases of the oblique angle of the die surface in the sheet metal forming processes. With each the simulation cases, the result shows that the wall thickness, material distribution and forming pressure are different for each various products. Moreover, the simulation results support a useful data table for the research and manufacturing in the deep drawing field.

Investigation of Sheet Thickness and Punch Force in Die Surface Angled Hydro-mechanical Deep Drawing Method

“…The factors affecting the change of punch force are the friction force between the die and the sheet metal material, the blank holder force and the deformation resistance of the sheet metal material. In the angled dies, it was determined that the blank holder force decreases with the angle increasing up to 5 degrees and is constant after this value [34]. With the 486 increase of the die surface angle, the decrease in the blank holder force decreased the punch force.…”
