- The research situation of gear forging at home and abroad and the application of numerical simulation technology in gear forging are introduced.
- The relevant theoretical knowledge of numerical simulation of forging forming is introduced.
- A multi-step analysis method for numerical simulation of spiral bevel gear forging process is proposed, and the upsetting process and die forging process of driven spiral bevel gear blank are analyzed in multiple steps.
- The method of extrusion forming bar drawing is put forward, which solves the problem of easy bending of forgings caused by free forging and drawing of driving spiral bevel gear and spiral bevel gear blank. The extrusion process and die forging process of driving spiral bevel gear blank are analyzed in multiple steps. However, extrusion has brought new problems: high energy consumption and low production efficiency.
- The drawing method of spinning forming bar is put forward, which solves the problems of large energy consumption and low production efficiency. A new spinning device is designed, and the spinning process is numerically simulated.
