An Upper-Bound Analysis of Closed Multi-Ram Forging of Rod
The shape of rod-shaped parts is complex, and the relative size changes more, so it is difficult to be deformed. Naturally the production of rod by closed multi-ram forging has many advantages. This paper introduces the analysis and calculation of the deformation load in auto rod pieces by closed multi-ram forging and the solve process of formula calculating deformation load of multi-ram forging, and then verified it by experiment. It has been shown that upper-bound analysis method is accurate in calculating the deformation load of multi-ram forging, and it can be used as the basis of the selection of presses and calculating the deformation load.
