The Study and Analysis of the Blanking Force of Fine-blanking with Negative Clearance and Common Blanking with AISI-1045

Fine-blanking with negative clearance is a special kind of metal plastic processing technology.Many experiments in fine-blanking with negative clearance and common blanking with AISI-1045are made.The actual blanking force curves is gotten.Simulation is carried on the blanking processes using Deform software,and theoretic blanking force curves and damage of the cross section.The contrast between experimental study and simulation shows that the fine-blanking with negative clearance force reduces more gently than common blanking and the quality of fine-blanking with negative clearance workpiece is better.
