It is difficult to ensure the size of the gearbox hanger blank drawing by free forging, which is inefficient, costly, and requires many inspection processes. In addition, the blank forged by free forging has a heavy feed and a large amount of cutting. The characteristics of railway products are large batches and complex shapes. The forging processing cycle of this forging solution is long, which affects the processing efficiency and is not suitable for use in batch products. The original forging solution for the gearbox hanger product is based on the maximum outer contour inclusion body of the part, with a processing allowance of 10mm extended outward, a large process excess filling, and a heavy feed.
