Skew rolling mill for reducing solid and hollow cross-sections

摘要

A skew rolling mill has three taper rolls, inclined at an angle to the axis of the rolled stock and offset relative to each other by 120 DEG . Each taper roll is driven through a bevel gear pair, intermediate shaft, intermediate gear and a planet gear, from a sun gear disposed on a rotatable hollow shaft. The roll and its drive are combined by means of a casing into a roll head. The casings are rockers which can pivot along the end face of the roll support and have pivot axes disposed outside the axes of the intermediate gears, in or near the common plane of the axes of the associated intermediate gear and planet gear. These pivot axes can be adjusted to a small extent in a guide extending perpendicularly to the common plane.
