在地图绘制冲压模具的试模(中文8100字,英文6400字)
美国专利7130708
摘要
金属板材成形是一种金属平板进入模腔形成产品的成型方法。吸收量是一个最重要的指标,控制所有冲压成形特点(应力),成形失败(劈叉、皱纹)和表面质量(扭曲)面板上的。一个新的模具冲压钣金零件重复一部分设计规范适应通过使用基于数学的冲压操作模拟特定的工程冲压条件下的特定部分的简化。冲压模拟是用来创建一个工程画地图的对比上选定位置加盖部分的外周边缘与原有的金属片的边缘对应的位置。生成的地图绘制在金属板的尺寸反映在所有模具的冲压件的冲压操作执行这样的位置对压边圈和凹模件压料面之间的金属片合适的位移。工程画尺寸模拟部分确定具体地点为适应集生产零件的模具压边圈胶表面系统的调整。

Title:
Draw-in map for stamping die tryout
    United States Patent 7130708
Abstract:
  Sheet metal forming is a manufacturing process in which flat sheet metal is drawn into a die cavity to form a product shape. Draw-in amount is the single most important stamping index that controls all forming characteristics (strains and stresses), formability failures (splits, wrinkles) and surface quality (distortions) on a panel. Adaptation of a new die set for repetitively stamping sheet metal parts to a part design specification is simplified by using a math-based simulation of the stamping operation under specified engineering stamping conditions for the specified part. The stamping simulations are used to create an engineered draw-in map comparing selected locations on the peripheral edge of the stamped part with corresponding locations on the peripheral edge of its original sheet metal blank. The resulting map of sheet metal draw-in dimensions reflect suitable displacements of the metal sheet between the binder ring and binder surface of the female die member at all such locations as the punch member of the die set executes its stamping operation. The engineered draw-in dimensions for a simulated part identify specific locations for adjustment of the binder ring/binder surface system in adapting the die set for production of parts.
