Abstract: The forming process and the stamping direction of back door inner panel were introduced, and the advantages and disadvantages of two opposite stamping direction were summarized. By understanding its characteristics, and considering part structure, the optimal process scheme was designed. The reason of the wrinkling on sealing surface and the countermeasures were analyzed, which shortened the debugging time of the die and ensured the forming quality and precision of the parts.
Key words: back door inner panel; process scheme; stamping direction; wrinkling
