Abstract:

PURPOSE: To stabilize the rotation of an inclined rolling roll by transmitting driving force through a gear from, a rotary housing to a rolling roll.

CONSTITUTION: A rolling device for a metallic long columnar body such as a tube or bar consists of 3 rolling rolls 1 whose rotating shafts are twisted in the same way and arranged obliquely, a rotary housing 2 supporting those rotary roll barrels with a cylyndical inside face, a fixed housing 3 supporting the rotary housing, a roll holding device 5 fixing a roll position and a driving device 4 for driving the rotary housing 2. In the barrel part of the rolling roll, a part 10 to be rolled and a contact part 11 with the inside face of the rotary housing 2 are made up in the shape of a gear and transmission of driving force from the rotary housing 2 to each rolling roll 1 is performed by its gear. Consequently, the number of rotation of each rolling roll does not change before and during rolling and the rolling rolls can rotate stably.
