Study on the Rapid Progressive Die Design of Sheet Metal with Free Form Surface
The structure of progress die is generally more complex and need higher precision, so it needs a longer development cycle, especially for the progress die design of sheet metal with free form surface. In this paper, taking a relatively complex part with free form surface for instance, NX PDW which has highly automated design capabilities was applied to finish the mold design, and the key steps and methods of designing such parts with PDW was put forward. In the design process, the stamping simulation software Dynaform was also applied to simulate the key process to predict forming defects and assess the formability of sheet metal. The results show that the application of Dynaform and PDW can improve the design quality and efficiency greatly.
