Metal flow is a very inhomogeneous process during backward extrusion of complex box.
针对某复杂盒形件的不规则形状和挤压变形时金属的不均匀流动,提出设计了挤压模的具有方向性的止流槽和凸模变圆角半径,并通过实验验证了止流槽和凸模变圆角半径控制金属合理流动的可行性,为同类型不规则或非对称零件的挤压成形提供了新思路。
Metal flow is a very inhomogeneous process during backward extrusion of complex box body,Relative shape and size of the blank is a key factor which affect metal flow.
复杂盒形零件的反挤压是一个极其不均匀的流动过程 ,坯料的相对形状及尺寸是影响金属流动的关键因素。
