摘　　要：T形锻件因形状所致,采用传统的整体凹模结构不能实现无飞边模锻。给出了不考虑摩擦的情况下T形锻件闭式挤压模具结构和依靠4个铰支撑板锁紧的纵向对合凹模结构的受力分析。锻件在两半凹模和冲头形成的封闭模腔中挤压成形,生产的锻件无飞边。The conventional structure of a solid concave die was not applicable for die forging of forgings without any flash,because of the T shape of forgings.A structure of closed extrusion die for T shape forgings and the analysis of forces were presented.The vertical halving concave die was locked by four gemel support-boards.The forging within a closed cavity was formed by a punch and two concave dies.The forgings without flash can be produced with the new type of forging die.
