In the 21st century, the key to whether the automobile industry can win the first opportunity in the fierce competition is how to develop high-quality products with low cost and short cycle. The product development cycle of all walks of life is gradually shortened, and the speed of product renewal is gradually accelerated. Improving product quality and shortening the development cycle have become the key to competition in all industries.
The processing technology of automobile rear axle spiral bevel gear is cold finishing after open die forging. The research method is to analyze the precision forging process of automobile rear axle driven spiral bevel gear by using DEFORM-3D finite element simulation software, and comprehensively analyze the metal flow, equivalent stress and strain, load and temperature distribution in the forming process, so as to optimize the forming process, Find the optimal forming scheme. With the increasingly wide application of finite element numerical simulation technology in the field of metal plastic forming, this method has become an important research method to solve the problem of plastic forming. Compared with the traditional physical experiment, this method simulates the processing process through finite element numerical simulation software, which has the advantages of low experimental cost and short time. It can effectively obtain the optimal processing scheme, guide the practical production and shorten the R & D cycle.
