ん断機まで送り込んでせん断している。The shearing machine of such billet manufacturing apparatus inserts and supports a metal material between the fixed grip and the slide grip, and moves the slide grip with respect to the fixed grip. Due to the structure of shearing the metal material, the sheared end portion of the metal material may be burred or deformed, and the metal material may adhere to the fixed grip portion due to high stress during shearing. On the other hand, the metal material is long and is good for continuous shearing to produce a billet, but if it is interrupted and sheared again, the remaining sheared metal material is returned to the heating furnace and heated. Then, it is sent to the shearing machine again for shearing.

して良好なせん断ができないことがある。However, as described above, the metal material comes into close contact with the fixed gripping portion and is difficult to separate from the fixed gripping portion, and the flash or deformation generated at the sheared end of the metal material interferes with the fixed gripping portion. It cannot be smoothly returned to the furnace, and when it is sent again from the heating furnace to the fixed gripping part, the burrs may interfere and it may not be possible to smoothly send it to the shearing machine. In particular, when the metal material is forcibly pushed by the pusher with the flash caught on the fixed grip portion, the metal material may be scraped at the flash portion, and the scraped material may adhere to the shearing machine to prevent good shearing.

できる。As shown in FIG. 6, the pusher 18 is returned to its original position to move the slide grip 17 upward,
The cylinder 26 is extended and the frame 21 is swung upward so that the tongue piece 24 is projected upward from the cutout recess 27 of the lower die 12. As a result, the metal material A is prevented from coming into close contact with the recess 12a of the lower die 12 and the shear end portion A 1 of the metal material A is located above the recess 12a of the lower die 12, so that the shear end Even if the portion A 1 is burred or deformed, the metal material A can be smoothly returned into the heating furnace 1 by rotating the feed rollers 10 and 22 in the reverse direction. Therefore, it is not necessary to provide a pusher for pushing out the metal material into the heating furnace and the maintenance can be improved. Further, since the tongue piece 24 extends close to the shearing surface of the lower die 12, it is possible to cope with the case where the metal material A and the lower die 12 are firmly adhered to each other or the remaining metal material A is short.
