軸継手９を介して連結されている。[Prior Art] A conventional example of a roller table device for a horizontally opposed forging press will be explained with reference to FIG. A plurality of stepped rollers 3 are arranged at required intervals in the press line direction, and the shaft portions 4 at both ends of the stepped rollers 3 are supported horizontally by a pair of bearings 6 fixed to a fixed frame 5 at intervals, and one of the shafts The portion 4 protrudes laterally outward from the bearing 6,
It is connected via a shaft joint 9 to a drive shaft 8 of a motor 7 fixed to the fixed frame 5 .

いう問題が生ずる。[Problem to be solved by the invention] However, the forged material l supported on the central large diameter portion 1
As both sides of O are pressed by the die 11, the width of the forged material 10 decreases and the vertical thickness increases, as shown in FIG. Since the height of the material lO support part remains constant, the material 10 to be forged extends upward, and its upper part protrudes above the upper part of the pressing surface of the die 11, and the projecting part is pressed. becomes impossible. Therefore, the problem arises that the material to be forged 10 cannot be forged into a predetermined shape, and the effect of forging the protruding portions cannot be sufficiently obtained.

。Furthermore, as a result of the decrease in the width of the forged material 10, the forged material 10 may fall from the large diameter portion 1 to the small diameter portion 2 when the mold 11 is separated, as shown in FIG. When the die 11 is approached in this fallen state, the material to be forged 10 will be pressed between one die 11 and the stepped portion 12 of the stepped roller 3; 3 is a fixed bearing 6
Since the bearing 6 is supported by the bearing 6, there is a problem that the bearing 6 is damaged by the impact force and the stepped portion 12 is worn out.
