Design and Optimization of Technology and Structure Parameters for Sheet Metal Drawing by Orthogonal Experiment

Abstract:

The deformability of sheet metal drawing is influenced by many technology and die structure parameters. By orthogonal experiment, the main four factors effected the deformability of sheet metal drawing have been studied in the two-stage drawing respectively. The results have shown the influencing order and optimum parameters of key factors were varied in different multi-stage sheet metal drawing. The influencing order of the four factors in the first drawing was the blank-holder force > dies radius>the lubricants>the punch-nose radius. The second drawing was dies radius>the lubricants>the punch-nose radius >blank-holder force. The optimum technology and structure parameters have been also determined by the experiments in the paper.
