Abstract：

The interference problem of traditional steel die roller stamping device has been solved by the soft and hard die roller stamping die, but there are still many defects in practice, such as the difficulty in adjusting upper and lower rollers and the large deformation in blanking of the sheet metal. Therefore, combined with the actual application of stamping die, the structure of the soft and hard die roller stamping die was improved, and the design of punch was optimized. Then, the wedge mechanism of lower roller height was optimized and adjusted to ensure the amount of overlap and achieve the levelness of the upper and lower rollers easily. Furthermore, the cylindrical punch of the flat edge in the roller press was changed into a hollow inner inclined blade punch to reduce the collapse depth after stamping and improve the flatness of sheet metal. The simulation and experimental results show that the proposed optimization scheme is feasible and can effectively improve the quality of stamping.
