Abstract：

In order to study the wear laws of the sharp edge forming die for aluminum alloy, for the aluminum alloy fender of a certain vehicle model with sharp edge design, the three-dimensional geometry model of drawing die for fender was constructed by using software CATIA, and the drawing process of fender was numerically simulated by the finite element simulation platform Autoform. Then, based on the numerical simulation results and Archard wear model, the secondary development was conducted by Python, and a simulation method and process for die wear analysis were established on the finite element simulation platform Autoform to quickly obtain the wear simulation results for the forming die of fender with sharp edge. Furthermore, according to the wear simulation results, the targeted surface strengthening treatment for the forming die of fender with sharp edge improves the wear resistance of the forming die for fender with sharp edge, and through mass production verification, the forming die of fender with sharp edge has no excessive wear, which could meet the continuous production requirements. The results show that applying the secondary development of Python to the finite element simulation platform Autoform can efficiently and accurately obtain the wear laws of the sharp edge forming die.
