| Abstract: | The technological property of automotive structural part, stamping process, technological scheme and layout design of the part were analyzed in detail. The structure of the die, main design points and manufacture process of the key components of the die were introduced. The large multi-position precision progressive die was designed and manufactured. Starting from optimizing layout, the multi-position progressive die replaced the original single-process dies and increased the work efficiency over by 3.5 tim... |
