Application Research and Analysis of Bending Springback of Semi-Circular Arc Stamping Parts Based on DYNAFORM

Abstract

Springback in the sheet metal stamping technology is a hot research subject in the sheet metal forming field. This article takes the semi-circular arc stamping parts as the objects of research. It aims at improving precision of the flanging forming parts and decreasing the bending springback. It analyzes the forming technology and deformation characteristics of flanging forming theoretically. Besides, it adopts the numerical simulation method to carry out research on the key factors influencing the forming process of semi-circular arc stamping parts (flanging and then bending) and the springback deformation, in order to find out the optimum production process scheme for semi-circular arc stamping parts.
