ROLLING MILL FOR SOLID ELONGATED PRODUCTS
A rolling mill for solid elongated products, defining a rolling axis, including first and second rolling stations. Each station includes a load-bearing structure, a removable roll-holder cartridge with three rolling rolls movable radially and rotating around spaced rotational axes, and a roll having a vertical rotational axis. A system synchronizes mechanical adjustment of the rolls. Three actuators mount on the load-bearing structure; three gear motor groups connect to the rolls by single extensions. The second station rolls are rotated 60° from the first stations. The rolls with a vertical axis of the first and second stations are arranged on opposite sides of the rolling axis. All rolling stations allow lateral extraction of roll-holder cartridges from the same side of the rolling mill. The stations on the extraction side have actuators movable relative to the load-bearing structure. The stations with vertical rolls arranged on the opposite side have fixed actuators.

Rolling unit
Rolling unit including at least two adjacent rolling stands, each having a pair of rolling rolls mounted on respective motorized shafts. The rolls of one rolling stand are disposed orthogonal and close to those of the adjacent rolling stand. The shafts are eccentrically supported in respective support elements, which are selectively rotatable around their axis and are each provided with rotation means to cooperate mechanically with an adjustment member suitable to make the support elements selectively rotate to determine an adjustment of the gap between the rolls. The rotation means of one pair of the support elements are directly connected kinematically to each other. The adjustment member is disposed, with respect to the rolling stands, so that the center of its gear lies very close to the line joining the centers of the support elements, so that a substantial part is contained in the bulk defined by the rolling stand.
