Optimizing Die Corner Radius of Deep Drawing Die

Abstract

The process of deep drawing plays a vital role in the production process of different parts in various process environments. Even though there is lot of variations in the production of parts during deep drawing with conventional processes to the latest automations in the manufacturing. There is a need to develop different die designs by varying input processes parameters for the deep drawing process in an optimum manner. The objective of the present study is to determine the influencing of die corner radius in deep drawing process and analyzing the process by varying the die corner radius. As the die corner radius plays a vital role in manufacturing the product in deep drawing process. Lower the die corner radii the part is subjected to tearing effect and higher the die corner radii, wrinkling is observed. The present work deals with the different die corner radii for stainless steel blank. Static analysis and transient analysis is carried out in ANSYS for (4, 5, 6, 7, and 8 mm) corner radii of the die.
