Abstract：

For the turbine shell used in hydraulic torque converter, the finite element model of turbine shell forming was established by software Simufact Forming, and two different turbine shell forming schemes were simulated. The simulation results show that the stamping force can be reduced by 27.1% by the blank holder, and 630 t machine tool can meet the stamping requirement of part. Furthermore, the springback of turbine shell was analyzed by software Simufact Forming, and the influence of stamping process parameters on the springback of turbine shell forming was studied. Then, it is found that the springback amount of turbine shell increases with the increase of die clearance, while it decreases with the increase of stamping speed. In addition, the stamping die of turbine shell was designed based on the results of finite element simulation, and it was verified by tests. The maximum springback of turbine shell is 0.442 mm by measurement, and the maximum simulation value of springback is 0.37 mm. Thus, the relative error between them is 16.3% which meets the requirements of sample manufacturing. Therefore, it provides an important guidance for the design of turbine shell forming die.
