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.

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.

The upper dies 13 and 16 are moved downward to form the recesses 13a and 16a and the recesses 1 of the lower dies 12 and 15, respectively.
The metal material A is gripped by 2a and 15a, and the slide grip portion 17 is moved downward with respect to the fixed grip portion 14 to shear the metal material A into a billet B having a predetermined length as shown in FIG. After this, the upper die 16 of the slide grip 17 is moved upward, and the pusher 18 is moved as shown by the phantom line in FIG.
Then, the billet B is pushed out to the billet holder 19. The lower die 15 may be moved up and down when the billet B is clamped. Further, the step of returning the metal material A to the heating furnace 1 by swinging the guide means 20 and the driving of the feed rollers 10 and 22 and the step of pushing the billet B to the billet holder 19 by the pusher 18 may be performed at the same time. Furthermore, when returning the metal material A to the heating furnace 1, a pusher 30 may be used together.

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.
