The blank Investigation of Square parts in Deep drawing

Deep drawing is an important and useful method to form different configurations like bath tub, shell box and etc from sheet metal. Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. In this process, the dimension and the blank of initial sheet metal must be obtained to reduce the material waste. The aim of this paper is to obtain the blank curve of rectangular plates. First, the actual simulation of deep drawing process is done by ABAQUS software. Then, by removing the non-deformed elements of the plate and exporting the remained sheet to the Solid Work software, the blank curve is determined. In order to check the method, the experimental deep drawing process was done on two sheet metals, one with rectangular configuration and the other with the obtained blank. The comparison shows the reduction of material waste (about 18.75%) for the sheet with the suggested blank.
