Study on Multi-Factor Blanking Parameters for Fine-Blanking with Negative Clearance through Simulation Optimization

Abstract:

The plastic analysis software DEFORM was used to simulate the blanking process of metal plastic without burr. Based on theory of the rigid FEM, the geometry model used for blanking with a negative clearance was established. The facts of influence the quality of the blanking work pieces were analyzed and concluded, at the same time, the parameters were indicated to improve the quality of the blanking work pieces. Through the experiment, the blanking load was measured with different clearance, thickness and material in group. The reciprocity between these facts was analyzed and the clearance was optimized. After the blanking load was regress analysis, the coefficient of the load and these facts were researched. Using quality analysis of the work pieces in the experiment, the thickness and the material were obtained which were suitable for blanking of metal plastic without burr. The reactions which were used to separate the metal were studied, which offered thereunder for proper remaining based on the better quality and smaller blanking load.
