| Popis: | 99 The purpose of this study mainly utilized the forging analysis software DEFORM-3D and the Taguchi experimental design method to simulate the three-dimensional manufacture processes for retaining groove of screw tail point die. The Taguchi experimental design method is applied to focus on the main factor of the simulation analysis, it can respond the difference levels of each factor, then a set of optimum design parameters can be learned for the retaining groove of each factor to increase the extent of the influence of the cavity filling. Analysis of a series of retaining groove forging results shows the filling ratio, the maximum principal stress and the equivalent stress are obviously affected by the retaining groove parameters. Effect of these parameters from high to low are: the retaining groove to the edge line from the cavity, the retaining groove depth, and the retaining groove width. In the mean time, the retaining groove has the best filling ratio when overlapping is staggered. The analysis results also show that after a new design of retaining groove, the product volume is increased, the equivalent stress is reduced, and the length of excess material is significantly reduced. Taguchi analysis result shows that the excess material length can be reduced 41.47%, product volume can be effectively increased, molding stress can be reduced 18.34%, and the equivalent stress can also be reduced 4.83%. The result of study can provide retaining groove designer a reference and reduce the bad products. |
