Description

带主法兰阀体锻件的多向模锻成形模具及成形方法Multi-direction die forging forming die and forming method for valve body forging with main flange

技术领域 technical field

背景技术 Background technique

目前，阀体锻件多采用两种成形方式，即普通模锻和水平分模的多向模锻。普通模锻时，分模面上存在飞边，同时无法锻出水平孔和垂直孔，锻件重量大，材料浪费较多。水平分模方式的多向模锻虽然可以锻出水平孔和垂直孔，但无法锻出主法兰，造成锻件机加工后零件重量大，安装较为困难。 At present, two forming methods are used for valve body forgings, namely ordinary die forging and multi-directional die forging with horizontal split die. During ordinary die forging, there are flashes on the parting surface, and horizontal holes and vertical holes cannot be forged at the same time. The weight of the forging is large and there is a lot of material waste. Although the multi-directional die forging of the horizontal die forging method can forge horizontal holes and vertical holes, it cannot forge the main flange, resulting in heavy weight of the forged parts after machining and difficult installation.
