Abstract：

The importance of generator claw pole in a generator and the influence of claw pole precision on the whole generator were briefly described. By analyzing the forging process of fourstation forging die, it is found that the fourstation forging die makes excess material flow into the lower die easily because of the larger lower die clearance in the process of forging and trimming, and makes the claw pole produce larger burr ultimately. At the same time, part of claw teeth open outward, the height of teeth is shortened, and the claw teeth deform. Then, based on forging analysis software Deform, the forging model was simplified, and the effective solution was proposed to reduce the lower die clearance and prevent the above problems effectively. However, the preprocessing parameters of software were determined according to the actual production situation of workshop, and the movement direction of material in the middle of claw pole in the preforging process and the final forging load of claw pole tip were analyzed. The results show that during the preforging simulation process, when the simulation reaches the 930th step, the preforging distance is completed, and the middle part of blank material shows horizontal movement. In the simulation process, the maximum forming load of claw pole tip can reach 672 kN which is consistent with the test results.
