冲模调试和冲裁实验的研究

Teaching Innovation Research for Stamping Experiment and Die Modifying

凸凹模刃口之间的间隙是影响冲裁件断面质量的重要因素 ,对实验冲裁模进行改进后 ,使凸凹模刃口之间的间隙可调 ,在实验时能观察到三种不同的断面质量 ,让学生理论联系实际了解间隙对断面质量的影响 ,拓宽了实验目的。

The clearance between cutting edge of punch and concave mold is an important factor in the sectional quality of stamping products. After improving the experimental die and making the clearance adjustable, three different sectional qualities can be observed in an experiment. This helps undergraduates understand how the clearance actually affects the sectional quality, and puts the experiment to a better purpose.
