应用价值工程原理改进模具设计

Use value engineering principle to improve die design

介绍了应用价值工程原理改进设计，提高了模具寿命。重点分析了冲裁间隙的功能及其对模具、工件的影响，说明在普通冲裁工艺中，选用较大冲裁间隙，能提高模具寿命。

Abstract Introduce the method to prolong service life of the die by using value engineering principle to improve die design.Analyse the functions of blanking clearance and its influence to the die and workpiece.Illustrate that only select fairly larged clearance in general blanking,die life would be increased.
