Forging is one of the main ways of manufacturing spiral bevel gears. The forging of spiral bevel gear can be roughly divided into two types: hot forging of spiral bevel gear blank (to prepare for subsequent machining) and precision forging of gear. Due to the importance of spiral bevel gear in mechanical equipment industry, it is necessary to study the forging forming of spiral bevel gear.
In recent years, with the development of computer technology and metal plastic forming theory, finite element numerical simulation technology has been more and more applied in metal plastic forming. Using the finite element numerical simulation technology, the plastic deformation process of metal in the forging process of spiral bevel gear can be simulated, and the flow law of metal and the distribution of stress, strain, displacement, velocity and temperature in the deformation process can be obtained; It can be observed whether the material folds, cracks and filling defects occur in the forging process; It can be observed whether the final shape of the forging is consistent with the actual forging. In addition, the stress of the die in the forging process can also be obtained, so that the strength and stiffness of the die can be checked. The obtained information can provide technical guidance for the design of forging die and the research of forging process. Using finite element simulation technology can greatly shorten the product development cycle, reduce the development cost, improve the product quality, and then improve the competitiveness of enterprises.
