Compact two-line rod-rolling stand

摘要

A two-line roll stand has a frame, an upper shaft on the frame, and two lower shafts on the frame spaced horizontally from each other below the upper shaft and forming with the upper shaft an isosceles triangle. Identical drive units each have a pair of rolls and gearing connected to the respective rolls. The lower shafts each carry three drive units and the upper shaft carries at least four of the drive units. The drive units of the lower shafts define a pair of roll lines spaced below and symmetrically flanking the upper shaft. The upper-shaft drive units are aligned on the lines with the rolls of the respective lower-shaft drive units. A single motor has an output directly connected to drive gears on the shafts for synchronously rotating all the shafts and thereby rotating all the rolls via the respective bevel gears and the respective drive units.
