Abstract
A cold pilger rolling mill includes a pair of rolls rotatably attached to a roll stand, a crank drive on a driveshaft, which is rotatably mounted around a rotation axis, with a counterweight attached to the crank drive at a radial distance from the rotation axis, and a push rod with a first and a second end. The first end of the push rod is rotatably attached on the crank drive wherein, during the operation of the mill, a rotation of the crank drive is converted into a translation movement of the roll stand between a first and a second reversal position. The radial distance of the first end of the push rod from the rotation axis is adjustable, so that the distance between the two reversal positions of the translation movement of the roll stand is adjustable.
