DESCRIPTION OF THE PREFERRED EMBODIMENTS In a situation where the other blade device (movable type) is at the limit of retreat, the upper side of the tool post of the other blade device and the one of the one tool device (a fixed type or a movable type) are opened. Unnecessary casting is charged into a charging opening (charging port) formed by opening upward. Thereafter, the other blade device moves forward along the circular orbit. At this time, the other blade device moves forward along the circular orbit, and the other half blade device (push blade) and the one blade device half blade device ( And the receiving blade) is in a mating relationship, and the cutting operation is performed. Overall, it has the following effects. The unnecessary casting is reliably broken by the breaking force due to the fitting relationship between the bottom crest on the bottom side of the push blade and the bottom crest on the bottom side of the receiving blade, that is, the vertical bending force. -1 The downward movement of the cutting device can be achieved by the pressing force (pressing stress) of the tip side peak portion on the tip side of the push blade and the tip side peak portion on the tip side of the receiving blade. -2 A breaking force is generated due to the fitting relationship between the tip-side crest of the push blade and the tip-side crest of the receiving blade, so that the cutting is reliably performed. -3 The tip-side peak of the push blade and the tip-side peak of the receiving blade have a shape protruding toward the tip, which helps to prevent scattering and enables safe work. By the above operations of -3, the following advantages can be obtained as a whole. The bottom and top ridges can concentrate unnecessary and broken castings on the cutting force, so they can be cut reliably and at low pressure, or the cylinder, the entire device can be downsized, or the running cost can be reduced. There are benefits to help. Unnecessary castings or broken castings can be broken, moved downward, and prevented from scattering, and efficient and safe processing can be achieved. Thereafter, as the other blade device moves forward, pressing and breaking by the blades (between the blades) (shear between the blades) or pressing and breaking by the tip-side ridge for preventing scattering is performed.

The reclaimed casting falls down the gap between the blades and is successively received by the lower blade, or reaches the next gap between the blades. Thereafter, the pressing, breaking, and dropping are repeated as appropriate, and from the convergent discharge opening (discharge port) formed under the gap between the blades of the one-side and the other-side blade devices or the tool post, the lower accommodating portion. Can be stored. In the structure in which the movable blade device is installed, the movable blade device is moved (moved) at the time of discharge to open the convergent discharge opening.

When the convergent discharge opening is opened (opened) or its size is changed, the other blade device is supported by using a crane, a supporting means or the like (hereinafter, referred to as a crane). The operation of pulling out and / or inserting the support block without the frame hole is sequentially repeated to move the bearing in the frame hole and change the number of both sides of the support block. Using this change, the size of the discharge opening can be changed or the discharge opening can be fully opened. Ideally, the movement of the support bearing is automatically performed by using a cylinder or the like, and a detecting means such as a sensor is provided to secure the accuracy of the movement. After the movement, since the position is determined by setting the support bearing, the support state is released. Further, after the movement, when performing repair or the like after setting the support bearing, it is preferable to work in a supported state with a view to ensuring safety. After the operation, follow the operation described above. When the support bearing is moved, a movable means such as a cylinder is swung to adjust the distance between the pivot of the blade tool and the support bearing, thereby achieving smooth and reliable movement of the support bearing. That is ideal.
