活扳手锻造自动线的研制与试验已经完成。整个自动线,包括予成形时的楔形模横轧在内,只需一火加热。楔形模横轧工艺,适用于对称形锻件精锻前的予成形,因为楔形模横轧后的产品具有圆形截面;然而对于不对称形的锻件,应用楔形模横轧予成形也是可能的。楔形模横轧机容易配备在生产率和材料利用率都较高而工序简单的自动线上。整个自动线予计可以减少人力,其至只有一人操作即可,并且改善了工作环境,如降低 Wrench forging automatic line of research and testing has been completed. The entire automatic line, including the wedge-shaped roll to be formed, includes only one fire. Wedge-shaped cross-rolling process, suitable for symmetrical forging pre-forging pre-forging, because the wedge-shaped cross-rolled products with circular cross-section; However, for asymmetric forgings, the application of wedge-shaped cross-rolling to shape it is possible. Wedge cross-type cross-rolling mills are easy to equip with automatic lines that have high productivity and material utilization and simple processes. The entire automatic line is designed to reduce manpower, to only one person can operate, and to improve the working environment, such as reducing
