THREEFOLD ROTATIONALLY SYMMETRICAL STAND HAVING AN ADJUSTMENT CONNECTOR

The present application relates to a stand (1) for rolling metal rods, wires or pipes along a rolling axis (19), which stand comprises a stand housing (10), the outside (12) of which, viewed along the rolling axis (19), comprises at least six side surfaces (14.1-14.6) that are arranged so as to be offset about the rolling axis, about a 60 rotation in each case, wherein in each case two side surfaces (14.1, 14.4, 14.2, 14.5, 14.3, 14.6) form a pair of side surfaces (14.1-14.6) that are located in parallel with one another. It further comprises three rollers (20.1-20.3) which are positioned on one roller shaft in each case, surround the rolling axis (19) in a star-shaped manner, and together form a caliber (21), and the radial position of which, based on the rolling axis (19), can be set for setting the caliber (21), and an adjustment connector (30) that is arranged on the outside (12) and is intended for introducing an adjustment torque for setting the caliber (21). In this case, the adjustment connector (30) comprises a gear shaft which is in parallel with a pair of the mutually parallel side surfaces.

THREEFOLD ROTATIONALLY SYMMETRICAL STAND HAVING ROLLERS MOUNTED IN ECCENTRIC BUSHINGS

The present application relates to a stand (1) for rolling metal rods, wires or pipes along a rolling axis (19), said stand comprising a stand housing (10), the outside of which, viewed along the rolling axis (19), comprises at least six side surfaces (14.1-14.6) that are of equal length and are arranged in a rotationally symmetrical manner about the rolling axis, wherein in each case two side surfaces (14.1, 14.4, 14.2, 14.5, 14.3, 14.6) form a pair of side surfaces (14.1-14.6) that are located in parallel with one another, and three rollers (20.1-20.3) which are positioned on one roller shaft in each case, surround the rolling axis (19) in a star-shaped manner, and together form a caliber (21). The three roller shafts are mounted by means of eccentric bushings in bearing holes of the stand housing (10) in such a way that a radial spacing of the rollers (20.1-20.3) from the rolling axis (19) is adjustable.
