The dimension of high speed train mounting plate two is 275.3 mm×112.5 mm×29.5 mm with an irregular Z-shaped bending part, and the Z-shaped structure is composed of two square holes, a round hole and a waist shaped hole with a drawbead in the centre. According to the complex structure of the forming workpiece, it were analyzed the stamping forming process, and three kinds of stamping schemes were confirmed. By comparison, the nine-position progressive die forming part was adopted in the end, and the strip nesting scheme was determined as pressed rib, pre-forming and shaping. Furthermore, the integral structure design of the mounting plate die, structure design of the pre-forming die and the die forming process were introduced in turn. The test shows that the multi-position progressive die design of the mounting plate is reasonable, and it can overcome the springback and meet the needs of the parts in mass production.
