本文应用严谨的方法,计算多工位冲压加工时拉深模模口圆角半径,从而提高产品的质量与生产率。应用多工位冲压加工的方法进行金属薄板深拉深时,经验和知识是十分重要的。至今,只有依赖于有经验的模具制造者、模具调整工和模具设计者,甚至还要包括生产工长,才能提高生产率。要成功地加工出产品,成形凹模适当的拉深模口圆角半径起着决定性的作用。拉深模模口圆角半径如果设计得当,会最大限度地减少工件的伸长和扭曲,可以防止侧壁或底部开裂。这种情况说明,工件和
In this paper, a rigorous method is used to calculate the fillet radii of the die-casting die during multi-station stamping to improve the product quality and productivity. Application of multi-station stamping process for deep drawing of sheet metal, the experience and knowledge is very important. To date, productivity has been raised only by relying on experienced mold makers, mold changers and mold designers, and even production supervisors. To successfully process the product, the suitable radius of die cavity fillet forming die plays a decisive role. Drawing Die Radius If properly designed, it minimizes the elongation and distortion of the work piece and prevents cracking of the side walls or bottom. This situation shows that the workpiece and
