Objective To investigate the flanging- upsetting process of flange. Methods Finite simulation software ABAQUS was adopted to establish the 2D planar symmetrical model to simulate the process. Die was designed for the experiments which were conducted on the 1000 kN servo press. Results A flange with the thickness equal to the initial blank was obtained after one time upsetting when the female die radius was 1. 2 mm and the clearance between the punch and die was in the range of 0. 80 ~ 0. 86. Conclusion The female die radius and the clearance between the punch and die obviously affected the quality of flange,which affected the upsetting process.
