Abstract：

The order of drawing is an important factor that influences the success of forming in the forwardreverse drawing. Then, for a special rectangle part with an ‘antidrum’ on its bottom, three different drawing schemes were developed according to its forming characteristics, namely, the two directions of the rectangular part were drawn in different orders. At first, the rectangular part was simulated by software Dynaform in different drawing schemes respectively, and then, the simulation results of three schemes were compared and analyzed to get optimum forming scheme. Finally, a kind of variableprocess composite drawing die was designed and made to verify the correctness of the simulations. The result shows that the correctness of the simulation results and the feasibility of ‘first reverse then forward drawing’ scheme are proved by experiments in the three schemes respectively.
