The stamping process of CD top shell for automobile was analyzed deeply, and the process scheme and the nesting were determined. With the size of automobile CD top shell is 176 mm×159 mm×50 mm, and the height of bending in three edges is 50 mm, it is not suitable for bending in progressive die. Therefore, it was conducted by an automatic line which was composed of a set of precision progressive die, a forming die and a manipulator. The structure of the die and main design points of the key components of the die were introduced in detail. The design of precision multi-position progressive die and automatic manufacture for the top shell were realized. Practice shows that comparing with five sets of single stamping used previously, the progressive die not only ensures the product quality, but also reduces the labor intensity, as well as improves the production efficiency significantly.
