In this paper, we optimize the parameters of the dies in the upsetting process, which breaks away from the traditional rounding connection between the head and the rod.Using the local cone-shape and rounding for free connection, we get the upsetting pieces which avoid the overlap defects in the performing process.Between the inner edge surface of the mounting panel and the solid bodies of the blade?close to flash line, there are no overlaps at all.Through these experiments, we avoid the common defects, and obtain more qualified forging pieces.
