一、引言楔横轧在国外是六十年代初开始用于生产的一项新技术,目前已在许多国家得到了广泛的应用。楔横轧适用于生产轴对称变截面的工件。楔横轧生产的工件,可以作为机器零件的毛坯,或作为模锻生产线上的“中间坯料”,即用楔横轧代替辊锻或其他工艺完成模锻前的“制坯工序”。二辊楔横轧过程如图1所示。坯料的变形是靠一对安装在轧辊上同方向旋
I. INTRODUCTION Cross-wedge rolling is a new technology used abroad for production in the early 1960s and has been widely used in many countries at present. Cross wedge rolling for the production of axisymmetric variable cross-section of the workpiece. Cross-wedge production of the workpiece, can be used as the rough parts of machinery, or die forging production line of the “intermediate material”, that is, using wedge cross-rolling instead of roll forging or other processes before the completion of the “preform process.” Two-roll cross wedge rolling process shown in Figure 1. Blank deformation is by a pair of rollers mounted on the same direction of rotation
