The invention relates to a device for moving a roll stand into or out of a roll stand receptacle of a rolling line, comprising a carrier element for entraining an entrainment element of a roll stand and a conveying element, wherein the carrier element is moved along a predetermined curved path.

Roll stand changing device

A rolling stand includes at least one roller having a roller journal which is rotatably supported by an eccentric bushing which in turn is rotatably supported by a low-friction bearing unit. An adjusting mechanism exerts an adjusting force on the eccentric bushing for rotating the eccentric bushing with respect to the housing and maintaining the eccentric bushing in a desired position. In order to determine a rolling force in the rolling stand, the eccentric bushing is rotated to a desired position relative to the housing by the adjusting mechanism, and an effective adjusting force in the adjusting mechanism is measured when the eccentric bushing is held in the desired position. The rolling force can then be ascertained on the basis of the measured adjusting force.

Rolling stand, and method for determining the rolling force in a rolling stand

A roll stand for rolling bar-shaped or tubular stock, having a stand housing, having at least one roll which is arranged on a roll shaft rotatably mounted in the stand housing and is connected in a rotationally fixed manner to the roll shaft via a frictional connection, in which roll stand the roll is held in its axial position on the roll shaft in a positive-locking manner by sleeve elements adjoining axially with respect to the roll shaft.

Roll stand for rolling bar-shaped or tubular stock

The roll stand having at least one roll shaft, which carries a rolland is subdivided into sectional shaftsfor the purpose of being able to change the roll, comprises at least one labyrinth-seal arrangement which is arranged in an annular gapformed between the respective sectional shaftand a bearing device for the roll shaft.

Roll stand for rolling bar-shaped or tubular material

A rolling mill for rolling or sizing of metallic pipes, bars and wires has a plurality of rolling units which are arranged on a straight line close to one another and can be exchanged in total, partly or individually, each of the rolling units having at least three rolls which are arranged in a star-like configuration around a rolling mill axis, drive shafts and motors each driving a respective one of the rolls in all the rolling units, a rolling unit housing provided for the rolling units, roll bearings provided for the rolls, and multi-part roll shafts provided for supporting the rolls so that the rolls can be exchanged without dismounting of the rolling unit housing and the roll bearings, the rolling units holding the rolls inside and outside of the rolling mill in their operational positions.

Rolling mill for rolling or sizing metal pipes

A rolling unit for a rolling mill for rolling or sizing metal pipes, bars or wires has at least three rolls arranged in a star arrangement. Each roll has a separate drive mechanism and is rotatably mounted on bearings on both sides of it. The rolls are adjustable radially together with the bearings. The improved rolling unit has smaller outside dimensions but can take a higher load. The number of individual rolling unit parts is also reduced as well as manufacturing and assembly expenses. For this purpose the bearings of the roll shafts are mounted in respective eccentric sleeves, whose rotational position may be adjusted manually and in a stepwise manner between several rotational positions.

A rolling unit for a rolling mill for rolling or sizing metal pipes, bars or wires has at least three rolls arranged in a star arrangement. Each roll has a separate drive mechanism and bearings on both sides of the roll. The rolls are adjustable radially with the bearings. A higher load can be borne with smaller outer dimensions. Furthermore the number of individual parts of the rolling unit is reduced as well as manufacturing and assembly expenses for the rolling unit. For this purpose the bearings of the roll shafts are mounted in respective eccentric sleeves, whose rotational position is continuously changed by means of an adjusting device. A securing device is provided however to fix the rolls in one rotational position.

A roller guide for a roll stand for precise guiding of a rod-shaped or wire-shaped rolling product in a caliber opening formed by rolls which engage the rolling product from an outer side and are distributed on its periphery, the roller guide has angular levers provided with legs on which the rollers are rotatably supported, turning pins on which the angular levers are turnable and which have turning axes extending transversely to a roll axis, an adjusting bushing by which the levers are jointly turnable so as to jointly displace the rollers radially to the roll axis, a coupling rod arranged between the adjusting bushing and each of the levers, the coupling rod being hingedly engaged on a leg of the lever which faces away from the rollers, and an angle between an engaging point between the coupling rod on the lever and a rotary axis of the roller with an apex point on the turning axis of the turning pin amounting to between 80 and 92.degree..
