Finite element analysis of the effects of tapered preforms on the final product in cold upsetting Dogan, O.; Gökler, Mustafa İlhan; Darendeliler, Haluk (null; 2002-12-01) The effects of the tapered preform shapes on the final product in cold upset forging are presented. As such, different preform geometries with different upset ratios are considered for the same final part geometry. In addition, the elastic-plastic finite element method is used to examine die filling and determine the flash volume in the final stage for different preform geometries. It is observed that, well-filled final products are obtained when the preform shapes and die cavities are designed according to...
Finite element analysis of header dies for taper upsetting Ceran, M.; Gökler, Mustafa İlhan; Darendeliler, Haluk (2006-01-01) In upset forging, the part is generally formed by a series of operations. Generally, taper upsetting stages are used as preforms. The geometry of the die cavity for the taper preforms can easily be determined from the dimensions of the hot part at the related stages; however the outer dimensions of the header die are determined by using some empirical formulae. In this paper, a commercial finite element code coupled with thermal analysis has been used to simulate hot upset forging process and to examine eff...
