摘要

针对铸造成型的减压阀壳质量低而机加工的减压阀壳体加工效率低且成本高的弊端,本文采用多向模锻工艺成形了减压阀壳体。研究了多向模锻工艺中的坯料位置、左冲头进给速率、右冲头进给速率三个工艺参数对减压阀壳体锻件质量的影响。结果表明,坯料中心相对于模具中心左偏移5mm,左冲头进给速率8.5mm/s,右冲头进给速率7.5mm/s为最佳的工艺参数。此时,左冲头和右冲头之间的载荷差值最小。
        Aiming at the defects of low quality of pressure relief valve shell made by casting and machining pressure relief valve shell with low efficiency and high cost, the pressure relief valve shells were formed by using multi-direction die forging process. The influences of three technological parameters (the position of the blank, the feed rate of the left punch and the feed rate of the right punch) in multi-direction die forging process on the quality of pressure relief valve shell forgings were studied. The results show that 5 mm left deviation of the center of the blank from the center of the die, the feed rate of the left punch of 8.5 mm/s and the feed rate of the right punch of 7.5 mm/s are the best process parameters. Under this condition, the load difference between the left punch and the right punch is minimal.
