Abstract：

For the complexity of detailed features for auto external door panel, which needs the applications of multiple fixture to ensure the size accuracy of sample, a flexible stamping trial technique was proposed. First, necessary forming steps of auto external door panel were analyzed. Combined with the characteristics of each step, the drawing, flanging and crimping steps about the auto external door panel were integrated into a set of fixture. Therefore, the drawing die was designed as an insert structure, and the flexible stamping of one die with multiple-position was realized by the inversion of insert and the reposition of trimming and parting line. Secondly, the application conditions of the flexible stamping trial technique were given. Finally, for the door assembly of a military vehicle, the process scheme and die of the flexible stamping trial technique were verified. The results show that the flexible stamping scheme can reduce two sets of fixture, save 45% cost and shorten the production cycle by 40% compared to the traditional one.
