直径达几英寸和长度达两英尺的多直径轴可在自动回转楔形辗压系统上,以每小时360-1200件连续成形,直径可保持在±0.003～0.010英寸(0.076～0.2540mm)内,长度保持在±0.003～0.006英寸(0.076～0.15mm)内。材料利用率约达90％,而且基本上可生产任何可锻金属或合金,工件温度分别为:钢2000°F,铝600℃,黄铜300°F～1200°F。该系统包括:压力机、成形装置,感应加热器、棒料或钢坯进给装置、棒料自动堆放台或钢坯输送机构等。该工艺流程为将直径在4英寸内的热棒料或钢坯
Multi-diameter shafts up to several inches in diameter and up to two feet in length can be continuously formed on an automatic swivel wedge rolling system at 360-1200 hours per hour with a diameter of ± 0.003 to 0.010 inches (0.076 to 0.2540 mm) The length remains within ± 0.003 to 0.006 inches (0.076 to 0.15 mm). The material utilization is about 90%, and basically any forged metal or alloy can be produced. Workpiece temperatures are 2000 ° F for steel, 600 ° C for aluminum and 300 ° F to 1200 ° F for brass. The system includes: presses, forming devices, induction heaters, bar or billet feeder, bar stock stacking platform or billet conveyor and so on. The process is a hot bar or billet with a diameter of 4 inches
