Research on forging simulation of spiral bevel gear blank

  1. The hot forging process of spiral bevel gear blank is completed at high temperature, and the metallographic structure of metal will change at high temperature. At the same time, heat treatment is also required for the blank after forging. It can be further studied in combination with the change of metallographic structure during forging and the heat treatment after forging.
  2. The metal flow law in the blank forging process was studied, and the influence of die structure, different initial forging temperature and friction coefficient on the forming effect was studied. However, due to many factors not considered, such as the change of metallographic structure in the forging process mentioned above, the specific optimization design of the die structure has not been carried out, nor has the optimal initial forging temperature and friction coefficient been determined, but only the qualitative study of the die structure The influence of initial forging temperature and friction coefficient on the forming effect verifies that the numerical simulation method can be used to optimize the die structure. It can also be further studied on the optimization design of the die structure, the determination of the optimal initial forging temperature and friction coefficient.
  3. Spinning device is designed to replace the original free forging process, the geometric modeling of the spinning device is carried out, and the spinning process is analyzed by numerical simulation. However, the spinning device has not been mapped, the physical spinning device has not been manufactured, the physical simulation has not been carried out, and the optimal roller rotation speed and blank feed speed have not been determined. In terms of spinning device design and numerical simulation, I have only done preliminary research, and there is still a lot of work to be further studied.
