Abstract:

Sheet metal forming die technologies show great progress in the industry daily. Sheet metal dies design depends on many parameters such as the product's geometry, the die dimensions to be designed, the number of products, and part operation. The main purpose of the designs is to design the die with optimum parameters and to obtain high-quality products.One of the reasons for these errors is the damage to the die elements during operation. This studyanalyzed the final process of sheet metal forming dies using a progressive two-axis in-die conveying system designed with Catia V5 software. The lifetime analysis of the matrix element used in the hole drilling process was made with Ansys software, in which the finite element method was applied. The analysis compared two materials used in die design, AISI D2, and AISI A2 tool steels. The effects of matrix thickness on fatigue life were analyzed separately for matrices with 8 mm, 10 mm, and 12 mm thicknesses. According to the analysis results, it was concluded that the longest fatigue life is in the dies with a 12 mm thick matrix in which AISI D2 steel material is used.
