Abstract：

Adopting active die-trapeziform groove constrained divided flow method,the die of spur gears with big modulus and high boss was specially designed.The formation of the spur gears was simulated by three dimensional rigid plastic finite element method.The technological experiment of the precision forging of spur gears with big modulus and high boss was carried out.The results show that the active die-trapeziform groove constrained divided flow applied in the process of forging is very effective to decrease the forging load.The perfect tooth filling,appearance precision of gears and good flow net pattern were obtained.The numerical simulation results are in good agreement with the experimental results.
