一、前言近年来,在锻造加工领域中,从节约材料费的观点出发,人们把注意力转向了全闭式模锻。为了避免因这种方法带来的过大载荷,在复杂形状零件的成形方法上,对闭式模锻寄予了极大希望。但是,在这种场合,为了使材料完全充满雕刻模角部,也需要相当的载荷,而且模具负荷也十分大。目前,有关无飞边锻造技术中有 First, the foreword In recent years, in the field of forging processing, from the point of view of saving material costs, people turn their attention to fully closed forging. In order to avoid the excessive load caused by this method, great attention has been given to the closed die forging in the forming of complex shaped parts. However, in this case, in order to make the material completely fill the corner of the engraving die, a corresponding load is required, and the die load is also very large. At present, there are no flash edge forging technology
