摘要： The embodiment relates generally to a stamping or draw die used for forming a workpiece into a part or component using a first die shoe, a second die shoe and a punch wherein the punch draws the material into a cavity located in the second die shoe. The force is generated during the forming operation are often unbalanced which generates an uneven stress distribution on the component of the die assembly. By varying the position and angle of the guide surfaces located on the punch, first die shoe and second die shoe the stress can be distributed across a greater area of the respective die assembly component to reduce stress concentrations in a localized area and correspondingly reduce the potential for die failure.
摘要翻译：该实施方案大体上涉及用于使用第一模具靴，第二模具靴和冲头将工件形成到零件或部件中的冲压模具或冲压模具，其中所述冲头将材料拉入位于所述第二模具模具中的模腔中。在成形操作期间产生的力通常是不平衡的，其在模具组件的部件上产生不均匀的应力分布。通过改变位于冲头上的引导表面的位置和角度，第一模具靴和第二模具靴可以将应力分布在相应模具组件部件的较大面积上，以减少局部区域中的应力集中并相应地降低潜在为了失败。
