突起をバリＡ２へ押し込みながら切断してもよい。As shown in FIGS. 3 (a) and 3 (b), the upper blade mold 24 of the present invention has a projection 31 which forms a recess in the burr B3 during the deburring process. By cutting the burr B3 with the blade portion 26 while pushing the projection 31 into the burr B3, the tensile force acting on the burr cut surface 32 in a direction perpendicular to the surface can be reduced. Therefore, the material flow from the forged product body to the burr side is reduced, and the counterweight can be prevented from falling in the axial direction. Note that a projection 31 that forms a recess may be provided on the burr A2, and the burr A2 may be cut while being pressed into the burr A2.

もよい。FIG. 3B shows an example in which a projection is provided on the upper blade type. However, the projection may be provided on at least one of the upper blade type and the lower blade type. However, from the viewpoint of the stability of the burr cutting, it is preferable to provide the protrusion only on the upper blade type. FIG. 3A shows an example in which the projections are provided continuously on the entire circumference of the blade mold, but the projections may be provided intermittently on the entire circumference.

In the projection 31, the height H is 0.2 mm of the burr thickness T.
It is characterized by being provided at a position in a range of not less than twice and not more than 0.7 times and a distance X from the blade portion 26 being not less than 1.0 times the burr thickness T and not more than 25 mm. By setting the projection height and its position in the above range, the tensile force acting on the cut surface of the burr can be effectively reduced. If the projections are too high, a problem occurs such that the burrs are broken at the projections. If the position of the projection is too close to the blade portion, a pulling force acts by pushing the projection, and if too far, the pushing effect is small. In addition,
Usually, the burr thickness T is about 1 to 15 mm.
