<p>The present invention relates to a driving device for pipe rolling rollers capable of transferring metal strips passing between rolling rollers by simultaneously rotating the rolling rollers positioned on an upper front, a lower part, an upper rear, and a lower part of a worktable to press a metal strip which is linearly transferred at a constant speed. According to the present invention, the driving device for rolling rollers comprises: a holder body fixated while being separated from one side of a worktable; a driving motor fixated outside of the holder body to generate a rotational force; a first power transfer part positioned on a front side of the holder body to transfer the rotational force of the driving motor to the rolling rollers positioned on the front side of the worktable to press the metal strips first; a first connection part to connect the driving motor and the first power transfer part such that the first power transfer part receives the rotational force of the driving motor; a second power transfer part positioned on the rear side of the holder body to transfer the rotational force of the first power transfer part to the rolling rollers positioned on the rear side of the worktable to press the metal strips afterwards; and a second connection part to connect the first power transfer part and the second power transfer part such that the second power transfer part receives the rotational force of the first power transfer part on a center of the holder body.</p> |
