The application belongs to the technical field of plate
processing, and particularly relates to a quota blanking method for a support ring part, which comprises the following steps: reserving an outer ring allowance in a
lofting drawing of the support ring, and not reserving an inner ring allowance and a thickness allowance. Based on actual production and manufacturing of the support ring part, the application can not be limited to a traditional extensive
cutting and blanking mode, can rely on other equipment and process methods, and can efficiently utilize production resources, so that different blanking methods are given according to actual conditions of the support ring part manufactured according to needs and different design conditions, and the purpose of reasonably distributing raw materials and manufacturing resources and effectively reducing production cost is achieved.
