First, forging processing plan
- The amount and tolerance of the excavator on the forging, the margin and tolerance in the height direction should be larger. When the excavator is forged, the metal inertia is very small or almost zero, and the groove is not easy to fill deep.
- Fillet radius The metal movement of the excavator on the forging is almost inert, so the radius of the fillet should be larger, which is good for metal activities and fills the depth of the full groove.
- Die forging slope Because the ejector is provided on the excavator, the die forging slope can be reduced, generally taking 3° to 7°; some can even be without slope.
