A horizontal or vertical roll stand for a rod or bar rolling mill comprising a pair of work rolls having a plurality of grooves spaced axially along the surfaces thereof, each work roll being journalled between bearings contained in bearing chocks, with the bearings being adapted to accommodate axial adjustment of the work rolls in relation to the bearing chocks. The bearing chocks are supported in a housing with the work rolls in parallel relationship and with the grooves defining a plurality of roll passes. An axial roll adjustment means is associated with each work roll. Both of the axial adjustment means are driven by a common axial adjustment drive. A clutch is connected between one axial adjustment means and the axial adjustment drive. When engaged, the clutch permits the axial adjustment drive to operate through both axial adjustment means, thus axially adjusting both work rolls simultaneously. When the clutch is disengaged, the axial adjustment drive operates through only one axial adjustment means, with the result that one work roll is adjusted axially in relation to the other work roll. The work rolls are additionally acted upon by roll parting adjustment means driven by a common parting adjustment drive. On vertical roll stands, the axial adjustment drive and the parting adjustment drive are supported on a platform overlying the roll housing. Both drives are connected to their respective adjustment means via couplings which are separated and assembled in response to vertical movement of the platform between a lowered operative position supported on the roll housing and an inoperative position spaced vertically thereabove.

Roll stand for a rod or bar rolling mill

In a rolling mill having a plurality of roll stands aligned along the mill pass line, each roll stand having parallel roll shafts carrying cooperating pairs of work rolls, with the roll shafts of at least some of the roll stands being offset 90.degree. with respect to the roll shafts of the other roll stands in order to eliminate the necessity for twisting the product as it progresses from stand to stand along the mill pass line, an apparatus for driving the roll shafts consisting of intermeshed gears carried by each pair of roll shafts for establishing a drive connection therebetween; a driven sprocket wheel connected to one roll shaft of each pair; a gear unit for each roll stand, each gear unit having an input shaft and an output shaft, the output shaft of each gear unit being parallel to the roll shafts of the roll stand associated therewith and having a driving sprocket wheel thereon; and endless chains for connecting the driving and driven sprocket wheels, the input shafts of the gear units being interconnected along a single drive line parallel to the mill pass line and being driven by a common power source.
