The bearing roller 2 does not rotate actively with the bearing plate 0, but rotates along with the plate 0 in the moving process, so that the function of changing sliding friction into rolling friction is achieved. In order to improve the conveying stability, it is preferable that a driven conveying roller 35 is arranged above the driving conveying roller 1, and the driven conveying roller 35 is driven by the plate 0 instead of being driven by the same bearing roller 2, and mainly plays a role in vertically limiting the plate 0. The plate material 0 is clamped between the driving conveying roller 1 and the driven conveying roller 35, and the driven conveying roller 35 is installed on a side frame.

The two ends of the roller 36 close to the end disc 37 are provided with a thread section 39 with external threads on the circumferential surface. The threaded section 39 is externally sleeved with a cylindrical adjusting cap 40, and the adjusting cap 40 and the threaded section 39 form threaded fit. The circumferential surface of one end of the adjusting cap 40 facing the center of the roller body 36 is provided with a circular limiting brim 41. The distance between the limiting edges 41 of the two adjusting caps 40 actually corresponds to the width of the plate 0.

Under the conventional condition, the industrial personal computer coordinately controls the driving conveying roller 1 to convey the plate 0 and the driving mechanism to drive the upper sliding block 5. The forging device and the conveying device are coordinated mainly by logic software implanted into an industrial personal computer. In addition, however, it is also possible to better practice the invention to connect the active conveyor roller 1 to the lower slider 7 by means of a clutch assembly, i.e. since the movement of the lower slider 7 is influenced by the upper slider 5, the movement of the upper slider 5 is influenced by the movement of the reduction motor 19. By adopting the mode, namely, the clutch assembly is utilized to realize the linkage control between the conveying and the forging. The clutch assembly has the effects that the driving conveying roller 1 does not convey the plate 0 any more when the upper and lower molds are closed, and the driving conveying roller 1 continues to convey the plate 0 when the upper and lower molds are opened.

As long as it is ensured that the relative position of the conveying motor 33 and the active conveying roller 1 is constant during the swinging of the swing frame 24.
The working process of the clutch assembly is as follows, when the clutch assembly is in the mold opening state, the pin rod 34 is positioned in the long pin hole 30, the driving conveying roller 1 is in contact with the plate 0, and at the moment, the conveying device is in the working state and drives the plate 0 to continue conveying. During the transition from the mold-open position to the mold-closed position, i.e., during the upward movement of the lower slide 7, the pin 34 is also constantly moving upward, and its movement in the elongated pin hole 30 in the vertical section 28 does not cause the swing frame 24 to swing. Until the upper and lower molds approach the clamped condition, the pin rods 34 move into the short pin holes 31 of the inclined sections 29. The swing frame 24 starts to swing, the active conveying roller 1 is separated from the plate 0, and the conveying of the plate 0 is stopped. Until the mold is opened again, the swing frame 24 swings back again to make the driving feed roller 1 contact the sheet material 0.
