Abstract：

According to the structure of nut side plate, the stamping process of the product was analyzed, and it was pointed out that tapping the nut side plate on the die was the difficulty for this set of die. Then, after modeling the product with 3D modeling software, the flattened drawing of this product was obtained, and the accurate blanking die sizes of the product were obtained. Furthermore, the strip layout of progressive die for nut side plate was introduced in detail, and the flanging hole process of the die was mainly analyzed. In addition, the nut-screw mechanism, gear mechanism, tap and other structures were installed on the die, the nut-screw mechanism converted the linear motion of the upper die into rotary motion by using the up and down movement of the upper die as the power source, and the tap was rotated by the gear mechanism. Thus, the tapping process in the progressive die was inserted, and in the production process of the progressive die, the tapping of the product was realized to substitute manual tapping and realize automatic production.
