摘要：

根据汽车加强板的形状、尺寸和生产要求，分析了其冲压工艺，进行了级进模的排样设计和模具设计。结合Dynaform软件进行工艺分析，确定了产品中心部位可一次冲压成形。针对产品弯曲部位多、成形后回弹量大的问题，采用预压工艺有效保证了弯曲精度；针对产品多边弯曲特征，采用框架式的排样结构提高了料带进给和冲压的稳定性；浮料导料销与导正销相结合，进一步提高了冲裁精度。生产结果表明：分次折弯的成形方案可以提高产品的精度；模具结构合理，可以保证产品的生产效率、良品率，并实现大批量生产，对实际生产具有重要的借鉴意义。

According to the shape, size and production requirements of automobile reinforcement plate, the stamping process was analyzed, and the layout and die design of progressive die were conducted. Then, the process was analysed combined with Dynaform software to determine that the central part of product could be formed at one time stamping. In view of the problems of many bending parts of product and large amount of springback after forming, the bending accuracy was effectively ensured by using the pre-pressing process, and aiming at the multi-sided bending characteristics of product, the stability of strip feeding and stamping was improved by using the frame-type layout structure. Furthermore, the combination of floating guide pin and corrected pin further improved the punching accuracy. The production results show that the forming scheme of bending in several times can improve the accuracy of product, the structure of die is reasonable, which can ensure the production efficiency and yield rate of product, and realize the large-scale production, which has important reference significance for the actual production.
