摘要
针对连杆的形状结构特点以及2A12高强度铝合金的成形加工特性,讨论了铝合金连杆预制件的形状尺寸确定方法和楔形横轧成形加工工艺过程;并对楔形横轧模具的布置以及楔形横轧模具的楔入段、展开段和精整段的设计计算过程作了介绍。
In view of the structural feature of a connecting rod and the processing characteristic of high strength aluminum alloy 2A12, a method to determine the shape dimensions of the aluminum alloy connecting rod pretreated blank was discussed, and the wedge rolling process was analyzed. The arrangement of the wedge rolling die was described, and the design and calculating procedure for the wedging zone, spreading zone and finishing zone were stated.
