Abstract：

The structure and stamping process of flange cover were analyzed, and a progressive die was proposed to produce the sheet metal parts of flange cover. Then, a tapping device was installed on the progressive die to tap the threaded holes on the flange cover. First, the strip layout of the progressive die for flange cover was introduced, and it was pointed out that the key processes for this set of flange cover progressive die were blanking, flanging, tapping and stripping, and the difficulty was to determine the step distance of the progressive die. Next, the method to determine the sizes of blanking die was described, and the calculation method of bottom hole diameter for flanging hole of part was mainly analyzed. Finally, the tapping device was introduced, which was installed on the die, and the tapping process for product was realized by using the up and down movement of upper die as the power source during the stamping process of die. In addition, because the distance between adjacent threaded holes on the part was too close, four threaded holes were tapped in two positions.
