Die Design of a Back Panel for a PDP TV Using 3-D Elasto-plastic Finite Element Analysis
The objective of this paper is the optimum design of dies for the back panel of a PDP TV with a large size. In order to design the geometry of these dies and an the initial size of the blank, three-dimensional elasto-plastic finite element analysis has been carried out using AUTOFORM V4.2. The corner radius of the upper trimming area of the die and the distance from the outer line of the blank holder to the outer line of the blank have been selected as design parameters to remove wrinkling associated with a stamping part in a trimming area. From the results of the analyses, it has been shown that a feasible product without wrinkles and skid lines can be obtained when the corner radius lies within the range of 6 mm to 8 mm and the distance from the outer line of the blank holder to that of the blank is 60 mm. Several stamping tests have been performed using the manufactured die set and the blank sheet according to the proposed optimum design. The results of the stamping tests have been shown that a back panel part for a PDP TV can be successfully manufactured using the proposed design condition.
