Abstract
A new forming process, upsetting-burring process is proposed to produce the parts with a flange from a thick plate. The usual burring operation used in the sheet forming was applied to the thick plate forming and the flange shape can not be obtained satisfactorily. The feature of the newly devised upsetting-burring process has been investigated in detail by FEM analysis and verified by a series of experiments with the aluminum plate. In the upsetting-burring process, the plate is upsetted partly and the upsetted material flows into the flange portion. By changing the upsetting height, width and the taper angle of the lower upsetting die, a flange with sufficient height and good shape accuracy can be formed successfully.
