In order to reduce the cost of stamping production, under the condition of the same material, thickness and similar output, the produced parts were designed by nested blanking. According to the actual situation of washer production, three kinds of washers were selected as nested blanking design. Under the condition that the blanking section and the dimension precision of part were not required highly, the dimension of part was adjusted slightly by making full use of blanking clearance and manufacturing tolerance of part, and the nested blanking parts were changed from two parts into three parts. Furthermore, the traditional three-washer compound die ejector mechanism was improved, and the connecting pin ejector was replaced by ejector rob and washer discharge sleeve driven by spring to reduce the failure rate and increase the service life of die. Thus, the reasonable application of nested blanking technology not only improvs the material utilization rate, but also simplifies the process, reduces the number of die, shortens the production cycle, and reduces the production cost of parts.
