- Abstract
For the potential defect produced in drawing progress, the response curved surface test was designed based on Box-Benhnken method by choosing the three important process parameters like the gap between punch and die, the equivalent force factor of drawbead and the blank-holder force as the key influencing factors. And the response surface model between the process parameters and the max thinning rate and the max thickening rate of seat support plate was established. Then the optimal parameters were obtained, which are 1mm for the gap between the punch and the die, 0.36 for the equivalent force factor of the drawbead, and 305 kN for the blank holder force. These optimal stamping parameters prove to be less than 3% in error in comparison with the simulation results, indicating a good agreement between physical and numerical data. The results show that it is feasible to optimize the process parameters by using the response surface method, which provides an effective method for the optimization of drawing formability for sheet metal.
