摘要：

分析了某座椅加强板的冲压工艺，确定了排样方案，介绍了座椅加强板多工位级进模的整体结构和主要零部件设计, 为保证条料的同步移动和送料顺畅，模具采用浮动顶料机构。确定了级进模模具设计方案，该模具充分利用工件本身的结构特点,采用了自动卸料、出料、少废料冲裁，有效提高了材料利用率。试冲结果表明，提出的排样方案和设计的9工位级进模是合理可行的，能够满足座椅加强板零件的大批量生产需要。

Through a stamping process analysis on the structure of the seat reinforcement plate, a layout scheme of a progressive die for the part was determined. The overall structure and design of the main parts of the die with multi-position punching and bending were presented. To assure the bar strip moving synchronously and running smoothly，lifting guide devices were used. Design scheme of the progressive die was determined. The full advantage of the structural characteristics of the workpiece itself was taken by the mold and less waste material blanking, automaticaly material unloading and discharging process were adopted, which can effectively improve the material utilization. The results show that the layout scheme and nine position progressive die are reasonable and feasible, and they are suitable for large-scale production of the automotive part.
