Research on Precision Die Forging Utilizing Divided Flow : 5th Report, Application to actual machine parts

The process utilizing the divided flow is applied newly to some machine parts such as a spline, a regular polygon and a spur gear with the purpose to clarify this useful process more universally. On the basis of the experimental data, its applicable range to these parts of various shapes and sizes is examined as compared with the respective expectations based on the upper bound theory. Through these examinations, it is concluded that the process utilizing the divided flow enables the precision die forging of the adopted parts under a lower working pressure and also enables the forging of the parts of various shapes and sizes within the range of similar working pressures. The process utilizing the divided flow, therefore, has wide applications to the cold precision die forging.
