| Abstract: | The feasible method of solving the bulging problem which always appears in the open die cold extrusion for spline shaft is put forward as follows:to add a guiding length at the die entrance to limit expanding of the bulging.On the basis of photoplastic experiment results, theoretical analysis of and calculating method of the guiding length relevant to the solution is also submitted. The solution and calculating method are successfully applied to experiment and practical process of forming spline shaft of 125cc motocycle. |
