The invention provides a stacking blank making device and processing method for large-scale ring forgings, belonging to the technical field of bearing ring forging equipment. An upsetting module is installed on one side of the transmission module, and a cutting core module is installed on one side of the stacked blind hole module. There is a rolling module on one side of the material core module. The invention is improved for the hydraulic blanking process of a large bearing ring forging production line and is applied to the hydraulic blanking process. During normal blanking, only one blank can be produced at a time. After the improvement, the two products are heated separately and then stacked together. After upsetting, punching blind holes and cutting flat end faces, the production of the upper and lower blanks is completed. Due to the presence of oxide scale during heating, the two products will not stick together and can be separated naturally after separation. The two blanks are returned to the furnace for heat preservation and rolled and expanded separately. The advantage of this stacked blank making process is that it can complete the production of two products in one blank making, which greatly improves the blank making efficiency of large ring forgings, facilitates processing, and reduces manufacturing costs.
