For the overlap defect in the drawing process of middle section for a certain brand automobile front hub package, the die structure was improved, and a new method of adding suction ribs was proposed. Then, the overlap defect was solved by adding suction ribs to absorb surplus materials, and the drawing process was simulated by software Autoform. Furthermore, the FLD and the wrinkle parameters were analyzed, and the correctness of the improved die structure was verified to determine the parameter of blank holder force. Through the production verification, the original overlap defect of products was eliminated, and the quality was qualified. The practice results show that it is feasible to eliminate the overlap defect by adding suction ribs. At the same time, the drawing effect was simulated and predicted in advance by the computer finite element simulation technology and software Autoform, and the real drawing quality displays to a certain extent. Thus, the better process parameters and die structure are obtained, and the die development time and the economic cost are reduced.
