为了验证对振动摆动辗压成形所作的理论分析的正确性,在确定摆辗力检测方法的基础上,结合成形工艺参数和振型参数,采用正交试验法设计了实验方案,并分别得到了不同实验参数条件下摆辗件单位面积上的变形抗力及其变形特征;分析了振型参数(频率和振幅)和工艺参数(摆头转速、每转进给量和成形温度)对摆辗件成形时间和变形抗力的影响;同时,还分别将普通摆辗件和振动摆辗件的形状、实际摆辗件和有限元模拟件的变形特征进行了对比。实验分析与比较表明,与普通摆辗相比,振动摆辗的成形力小、成形时间短、成形质量高,且所取得的实验结果与理论分析及其有限元模拟结果一致。
In order to verify the correctness of the theoretical analysis of the vibration swinging forming, based on the determination of the detection method of the swing force, the orthogonal experimental method was used in combination with the forming process parameters and the vibration mode parameters, and the experimental results were obtained respectively The deformation resistance and deformation characteristics per unit area of the pendulum under different experimental parameters were analyzed. The effects of the shape parameters (frequency and amplitude) and process parameters (pendulum rotation speed, feed per rotation and forming temperature) Time and deformation resistance. At the same time, the shapes of the ordinary pendulum and the oscillating pendulum, the actual pendulum and the deformation of the finite element simulation are compared. The experimental analysis and comparison show that compared with the ordinary roller, the oscillating roller has the advantages of small forming force, short forming time and high forming quality. The experimental results obtained are consistent with the theoretical analysis and finite element simulation results.
