φ28锚链横档模锻件如图1所示,该锻件两端R14.5mm圆弧处不允许有拔模斜度。但在整体模锻时不可能没有拔模斜度,而且横档边缘难以充满,锻件出模困难,模具易在模膛水平投影面的四个尖角处开裂。同时,模膛深处的加工和测量也较困难。为了解决上述问题,伐们改用分模模锻的锻模,在315 t单点闭式压 φ28 anchor chain cross-die forgings shown in Figure 1, the forgings at both ends of R14.5mm arc allowed draft. However, the overall die forging can not be without draft, and the edge of the cross-piece is difficult to fill, forging die difficult, the mold is easy in the mold horizontal projection of the four sharp corners crack. At the same time, the depth of the mold processing and measurement is more difficult. In order to solve the above problems, the cutting die to die forging die, 315t single-point closed pressure
