Based on the analysis of the number, structure and process characteristic of stop plate part, it was determined that the parts were produced by a progressive die. The layout drawing of progressive die was designed which indues nine steps such as blanking, bending and deep drawing etc.,and the technological properties of blanking, deep drawing and bending were described. At the same time, the key points of design for the multi-station progressive die structure were introduced such as the reasonable step design, the accurate location of part, the stable feeding for strip, and the guide design that met the accuracy requirements. Furthermore, the guide plate was adopted to guide the strip, the side edge was used for rough positioning, and the guide pin was used for precise positioning to ensure the accuracy of positioning, the spring stripper plate with the small guide pin and small guide sleeve was selected to press and remove the strip to improve guiding accuracy, the limit column was set to prevent the stripper plate from moving excessive distance and causing damage to the die, the bending process was designed as bending downward, the ejectors were arranged on both sides of the strip to ensure that the strip was fed smoothly, and the formed parts were obtained by blanking. Finally, the die components required for the progressive die of stop plate were designed by computer-aided design tool CATIA and assembled to obtain the three-dimensional digital modeling of die assembly.
