Compared with the traditional cutting process, gear swing rolling process is a completely different process method. It adopts forging process, uses the plastic deformation characteristics of metal and the constraints of die cavity surface, so that the blank can be directly formed into gear. Specifically, it refers to the gear manufacturing technology that uses swing rolling technology, the gear teeth are forged directly from the blank, and the tooth surface does not need cutting or only needs a little finishing, that is, it meets the use requirements. Compared with cutting, it has unique advantages. The deformation force required for swing rolling forming is small, and the forming effect is equivalent to the forging equipment with a nominal pressure of 5-20 times that of conventional cold forming.
Due to the reasonable distribution of metal fibers in rotary rolling parts and the processing strengthening in the process of rotary rolling, the mechanical strength of finished parts is greatly improved. When the swing angle increases from 1 at 2, the forming time is roughly reduced by 400%.
- Reduce production cost and save metal materials;
- Improve mechanical performance and gear quality;
- Improve production efficiency;
- Greatly reduce environmental pollution, which is conducive to sustainable development;
