摘要：

介绍了一种轿车安全带螺母板级进模的应用，通过对安全带螺母板冲压工艺及模具结构的分析，在一套级进模上采用7个工序完成零件的冲制。在第1工序中采用冲制定位孔来实现下一个工序的定位，设计了导料块来进行板件的初定位，导正销用于工件的精确定位，保证零件的精度。通过生产试验验证可知，采用该冲压工艺及模具结构生产的安全带螺母板总精度达到100%，满足了整车对产品精度及品质的要求；采用多工位连续生产可以提高模具的生产效率，降低生产成本。

It was introduced a nut plate progressive die for car seat belt. Based on the analysis of the stamping process and die structure of the nut plate, the part was completed in seven steps on a set of progressive die. In the first process, the positioning hole was punched to realize the positioning of the post process, and the guide block was designed to carry out the initial positioning of the plate parts. Furthermore, the guide pin was used for the accurate positioning of the workpiece so that the precision of the parts was ensured. According to the actual production verification, the total accuracy of the safety belt nut plate of the stamping process and die structure reaches 100%, which can meet the requirements of the whole vehicle for the precision and quality of the products. The production efficiency of the die is improved by multi-station continuous production, and the production cost is reduced.
