Comparison of Common Deep Drawing Steel Sheets in terms of Blank Holder Force and Friction Conditions

Abstract

In this study, it is aimed to make comparison of four different steel sheet materials that are widely used in deep drawing applications by taking blank holder force and friction conditions into account. Comparison is made between a standard steel which is generally used in white goods manufacturing (DC01), an ultralow carbon steel (DC04), a deep drawing steel suitable for cold forming (DD13) and an extra deep drawing steel resistant to ageing (DD14), which are preferred when manufacturing a part by deep drawing, if there is not any special material requirements. The purpose of this study is to make selection between these mentioned materials easier. Simufact.forming, a plastic deformation analysis software based on finite element method, and material database of the software was used in the conducted analyzes. Various blank holder forces were applied and friction conditions were changed for each material. By investigating obtained results, it was seen that there is a significant difference between deep drawing behavior of these materials and DD14 has high deep drawability even under high blank holder forces with low energy. Moreover, it was observed that friction conditions have a significant influence on effectiveness of deep drawing process.
