A lot of simulation research has been carried out on the production process of driven spiral bevel gear blank and its closed die forging die, which has obtained many theoretical basis for actual production. Due to the limitation of time and conditions, the outlook is as follows:
(1) The whole manufacturing process simulation of a certain size driven spiral bevel gear blank is completed, and the forming behavior of blank and die in the plastic process is systematically analyzed. However, due to the complexity and time of process design and die design, a set of CAPP system of this basin tooth part can be developed in the future research to shorten the design cycle and improve the design efficiency.
(2) The analysis of energy consumption in the ring rolling process is completed, but the residual stress and strain in the ring workpiece after deformation still need to be studied. In addition, this paper only studies the influence of preform on a certain rolling defect, and other rolling defects such as dish defect and flash also need to be studied.
(3) The thermal fatigue and wear of hot forging die are affected by many factors. Due to the time relationship, only some parameters are selected to analyze them respectively. For other factors, further research and exploration are still needed to understand the thermal fatigue behavior and wear behavior of die more comprehensively. In addition, this paper only simulates and calculates the adhesive wear of the die. Due to the diversity of wear and the change of the initial conditions of the die during repeated forming, it obviously can not fully reflect the real working state and real wear of the die. Therefore, the calculation of other wear forms should be considered in the future study of die life.
(4) Die failure includes wear failure, fatigue failure, fracture failure, plastic deformation and so on. Only wear failure and fatigue failure are analyzed, which obviously only reflects the service life of the driven spiral bevel gear blank closed die forging die. In the future research, other failure cases should be analyzed theoretically.
