Study On Power Spinning Of Wheel Felloe

Currently aluminum alloy wheel as the highest security requirements for spare parts in a vehicle, its manufacturing technology is also constantly developing. Forged aluminum wheel has the best quality, however, the high cost and low efficiency. In recent years, Europe and the United States gradually replace the traditional production process by spinning and forging aluminum alloy wheels in wheel industry. Spin-forming wheel is developed on the hot forging process, spinning forming before forging billet, and improves the manufacturing precision and mechanical properties.By contrast with many developed countries of the world, our studies have been lagged. Wheel spin-forming mechanism of the deformation in theory is not very mature, and can't find the specific practice which can be used to guide the production practice.According to forging and spinning technology, taking boundary condition, contact ,trajectory and friction into account in according with realistic processing of experiment, ABAQUS software is applied to 3D numerical simulation of power spinning of aluminum alloy wheel process and stress and strain distributions on shaping is considered. Rule of radial direction distortion of metal, variety of stress, strain and spinning force with the certain ratio of thinning and different roller feeding rate were analysis. In the end, associate with result of experiment, all kinds of vices of aluminum wheels'deforming were analysis as well as how to be.Experimental results justifies numerical simulation, which sets up ground for further studying of mechanism and features of general power spinning of forging and spinning aluminum alloy wheels. It also provides experience for the precision forming of the similar complex parts and provides optimizing of process parameters with effective methods and reliable support.
