In sheet metal forming process, as sandwiched between the punch and die as the processing of sheet metal to become increasingly thin, resulting in sheet metal to the die cavity of the flow resistance increases, thereby Au Cavity impede the flow of material, so the use of conventional sheet metal forming process can not be processed on convex sets with a high of stamping parts. This paper studies the area of ultra-high physical convex sets of parts and, based on numerical simulation and experimental results of a series of processes, development a set of continuous mode, won the ultra-high-convex sets stamping parts. studies have shown that the use of bending, upsetting-extrusion complex new process method to achieve the processing of sheet metal stamping parts with ultra-high-convex sets, but also with the components relative to the other processing methods The new process has many advantages over
