摘　　要：作为一种连续局部塑性成形工艺,滚珠旋压被应用于制造铝合金薄壁筒形件。介绍了滚珠旋压的基本原理,以塑性力学为基础,分析力学参数对旋压件成形性的影响。实验中通过采用LF2和LY12两种铝合金筒坯,获得金属材料的塑性和屈服强度对旋压件可旋性影响的一般规律。最后研究咬入角对金属材料稳定流动的影响,并通过实验获得了合理的咬入角值。As a successively and locally plastic deformation process, gall spinning is applied for the purpose of manufacturing thin-walled tubular parts of aluminum alloy. The basic principle with respect to ball spinning is introduced, and based on plastic mechanics, the influence of mechanical parameters on formability of spun parts is analyzed.During experiments, aluminum alloy LF2 and LY12 are used in order to obtain the influence of plasticity and yield strength of metal materials on spinnability of spun parts. In the end, the effect of attack angle on stable flow of metal materials is researched and the appropriate value of attack angle is derived from experiments.
