Abstract

This paper studies the design of rotary forging shafts based on the manufacturing process, with a focus on the comparative analysis of the traditional manufacturing process (mandrel-free process) and the improved process (mandrel-included process). By comparing the differences between the traditional and improved products in the manufacturing process, the improvement effects of uniform inner diameter and the mandrel-included process on product performance, manufacturing efficiency and production cost were analyzed. The test results show that the adoption of the mandrel-included process can effectively improve the quality of rotary forging shafts, reduce processing time, expand the range of material selection, and avoid the inner surface defects and low roundness problems that may occur in the traditional mandrel-free process.
