楔横轧是利用装有楔形模具转向相同的轧辊或作直线相向运动的两个平板来横轧毛坯。轧制时楔形模具楔入毛坯并使之旋转,利用楔形模的倾斜侧面来压缩和碾压金属,使毛坯的直径减少,长度增加,以得到所要求的轧件(图1)。 楔横轧适用于生产各种变截面轴类工件,如图2所示。该工艺既可直接 Cross wedge rolling is the use of wedge-shaped mold with the same roll or for the linear movement of the two flat plate to cross-billet blank. During rolling, the wedge dies are wedged into the blank and rotated, and the slanting sides of the wedge dies are used to compress and roll the metal to reduce the blank diameter and increase the length to obtain the desired rolling stock (Figure 1). Cross wedge rolling for the production of a variety of cross-section axis of the workpiece, shown in Figure 2. The process can be direct
