Abstract：

The stamping process of corrugated plate and its springback control method were studied. Firstly, the process analysis of corrugated plate was carried out and its finite element model was established, and then the die structure was designed according to the simulation results. Finally, taking the springback angle as the evaluation index, based on orthogonal test, the influences of process parameters such as stamping speed, friction factor and punch fillet radius on the springback of corrugated plate were studied. The range analysis finds that the influencing order of various factors to the springback is as follows: punch fillet radius>stamping speed>friction factor. The best combination of process parameters is the punch fillet radius of 1.8 mm, the stamping speed of 4 mm·s-1 and the friction factor of 0.13. Through servo stamping test, it is found that the springback angle of corrugated plate is reduced from 2.64° to 1.53°. The results show that the used forming process analysis of corrugated plate is correct, the die structure design is reasonable, and the springback of corrugated plate is effectively reduced by optimizing the process parameters.
