There are many factors affecting the precision forging of driven spiral bevel gear, large forming load, complex metal filling process, poor material fluidity, and difficult to guarantee the die life and product quality. These problems seriously affect the practical process. The precision forging process of spiral bevel gear is analyzed and studied by experimental method. Due to the influence of die material, high cost of precision machining after forging, large workload and equipment processing capacity requirements, it is impossible to carry out series experimental work. However, it is difficult to correctly analyze this kind of complex precision forging process by using mechanical analysis method.
With the rapid development of computer technology, it is very necessary to use modern computer technology and finite element technology to simulate the precision forging process of spiral bevel gear. The combination of the two makes it possible to analyze and predict the defects in the precision forging process of spiral bevel gear. The combination of finite element numerical simulation and physical simulation is one of the important methods to solve the complex problems in various metal forming processes. This method is currently used by many researchers. With the expansion of application field and the deepening of research, it also tends to mature gradually.
Through experimental research, the metal flow law in the precision forging process of driven spiral bevel gear is verified, the precision forging grid forming test of lead blank is successfully completed, and the metal flow of each part of the blank in the forming process of driven spiral bevel gear is obtained. It is proved that through experimental research, the physical test grid section is obtained, which is consistent with the results of numerical simulation analysis, and the metal flow law tends to be consistent, The two match very well. Therefore, the correctness and rationality of the numerical simulation results are also verified.
