Abstract：

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.
