Investigation on Hole Punching Process with Combined Punch to Improve Surface Quality during the Materials Forming Process

Abstract:

The present work shows the viability of a combined punch that makes possible to perform a hole punching followed by a hole burnishing in only one operation. The advantage of this combined punch is forming processes in only one process on medium thickness plate. In this work were tested two different configurations of punches which one of them is the conventional punch and another is a new structure of combined punch. The new structure of combined punch is added the step and inclined edge at the cutting edge on the basis of conventional punch. They are made of the same materials that are Cr12MoV. The new structure of combined punch and the conventional punch are studied by using numerical simulation and experimental research in this paper. During the materials forming process of hole punching, the simulation software ANSYS is used to simulate. The YZ32-100 Hydraulic press with nominal and the self-made die sets and the thick of 16mm Q235 sheet metal is selected in this experiment. The analysis of the obtained results showed that the hole surface quality of combined punch is superior to the conventional punch. It is prove that the new structure of combined punch can improve quality of punching.
