Abstract：

The design of multi-station progressive die layout was carried out by the actual production demand of locking arm, and the single layout structure was adopted based on the structural characteristics of locking arm parts. Then, the whole die adopted the sequential structure, and the part and scrap were separated automatically during each punching process. The concave die adopted the insert structure, which was more convenient to process and easier to maintain the die and replace the wearing parts. The double side edges were arranged on both sides of guide slot, and the material edge entering the die formed a positioning notch, which was fed along the guide slot close to the concave die. Therefore, the continuous stamping was possible, so that the utilization of stroke times for press reached 100%, the production efficiency was high and safe, and it was also convenient for the mechanization and automation of the stamping process. In order to ensure the accuracy of stamping and parts, the guide pin was designed in the blanking station, and the bending process one by one was adopted to reduce the springback in the bending process. As a result, through the actual production verification, the designed multi-station progressive die of locking arm could meet the actual production requirements.
