Abstract：

According to the structural features and process analysis of multi-anger motor bracket, the layout of strip was optimized by the second-developed CAD software to obtain the layout methods with less scraps in the width direction and no scraps along the feeding direction, and the stamping process scheme with fifteen-station progressive die was determined to form the part. Then, the π-type floating mechanism of strip was designed, that is, a round rod was set up between two floating support blocks, and the depth of avoidance groove for the round rod on the lower die was slightly larger than the diameter of the round rod, so there was no need to process a deep avoidance groove, which improved the strength of the lower die. Furthermore, the self-locking slider mechanism was presented, which consisted of a movable slider and a static slider. After forming, the movable slider slid obliquely upward for a certain distance and then completed the self-lock, and the horizontal distance of sliding was greater than the height of convex hull under the moveable slider, which realized the upward movement of strip freely. Finally, the lateral forming mechanism was discussed, and the slider of the mechanism had a long stroke to avoid the forming defects caused by the short sliding distance of other mechanisms. The test results show that the multi-station progressive die for the multi-anger motor bracket has a compact structure and reasonable process design to meet the requirements of dimensional accuracy of parts and batch production.
