近年来,在锻压生产中已采用楔形模横轧工艺来加工阶梯形元柱毛坯。这种横轧工艺与纵轧不同。纵轧时,毛坯的延伸方向与轧辊的运动方向相同,而楔形模横轧时,毛坯的延伸方向是与轧辊的运动方向垂直的。楔形模横轧时,工作模具一开始便压进坯料里,然后,随着模具斜棱以一定角度扩展,便使金属沿坯料轴向流动。楔形模热轧法可生产带精车留量(个别情况下甚至是磨削留量)或供模锻用(不必另行加热)的高精度产品。
In recent years, the wedge-shaped cross-rolling process has been used in the forging production process to process the ladder-shaped cell blank. This rolling process and vertical rolling different. During longitudinal rolling, the direction of blank extension is the same as that of the roll, while the wedge cross-rolling, the blank extension direction is perpendicular to the direction of movement of the roll. Wedge-shaped cross-rolling, the working mold from the beginning will be pressed into the blank, and then, as the mold beveled at an angle to expand, so that the metal along the billet axial flow. Wedge-die hot rolling produces high-precision products with precision stockpile (in some cases, even grinding stock) or for forging (without additional heating).
