法兰是水压机锻造较常见的一类锻件,由于受设备结构尺寸的限制,要在1600t水压机上锻制出外径2400mm、厚340mm的大法兰,是一项困难的工作。 1600t水压机的最大净空距只有2550mm,下限程套之间的距离仅1850mm,其允许的最大扩孔外径≤1800mm。由于实际生产任务的需要,我们在1600t水压机上大胆革新,成功地锻制出5个外径2400mm的釜端法兰(见图1)使水压机的扩孔能力增长了33％,充分发挥了设备潜力。
Flange is a common type of hydraulic forgings forgings, due to the size of the equipment structure constraints, in the 1600t hydraulic press forging a large diameter of 2400mm, 340mm thick flange, is a difficult task. 1600t hydraulic press maximum clearance is only 2550mm, the distance between the lower limit of the sleeve is only 1850mm, the maximum allowable expansion hole diameter ≤ 1800mm. Due to the actual production tasks, we made bold innovations on the 1600t hydraulic press. Successfully forging five end-capped flanges with an outer diameter of 2400mm (see Figure 1) increased the hole-expanding capability of the hydraulic press by 33% and gave full play to the equipment potential.
