通过有限(FEM)元速度场研究了冷轧铜铝双层板的复合过程,将该过程中金属的变形特征进行了分析,同时,将有限元计算结果与某工厂数据相结合,分析了轧制速度、压下率、异径同步、异径异步对铜铝双层板复合的影响。结果表明,速度场模型能够更有效地说明铜铝板的复合过程;轧制速度越大,变形区出口处复合面金属流动的同步性越差,复合强度越低;异径同步轧制铜铝复合板时,辊径比取1.4~1.6,变形区出口处复合面金属流动的同步性越好,复合强度较高;异径异步轧制铜铝复合板时,轧制速比取1.2,变形区出口处复合面金属流动的同步性越好,复合强度较高。
The finite element (FEM) velocity field was used to study the composite process of cold-rolled Cu-Al bilayer plates. The deformation characteristics of the metal in the process were analyzed. At the same time, the finite element calculation results were combined with the data from a factory. Effect of Producing Speed, Reduction Ratio, Reducing Diameter, Asynchronous Asynchronous on the Complexation of Cu - Al Double Layer Sheet. The results show that the velocity field model can explain the compounding process of copper and aluminum plate more effectively. The greater the rolling speed is, the worse the synchrony of metal flow at the exit of the deformation zone is and the lower the composite strength is. Plate, the roll diameter ratio of 1.4 to 1.6, the deformation zone exit composite metal flow at the synchronization of the better, higher composite strength; different-diameter asynchronous rolling of copper-aluminum composite plate, the rolling speed ratio of 1.2, the deformation zone The exit surface of the composite metal flow synchronization better, higher composite strength.
