Cold pilger rolling mill for forming a hollow shell into a tube, with a pair of rolls (2, 3) which are rotatably attached to a roll stand, and with a rolling mandrel as tool, with a feeding clamping carriage for receiving the hollow shell, wherein, during the operation of the mill, the feeding clamping carriage moves between a first (E 1) and a second extreme position (E 2) in such a manner that the hollow shell moves stepwise in the direction toward the tool (2, 3, 4), with a crank drive on a driveshaft, which is rotatably mounted around a rotation axis, with a counterweight attached at a radial distance from the rotation axis to the crank drive, and with a push rod with a first and a second end, wherein the first end of the push rod is rotatably attached on the crank drive around a crank pin at a radial distance from the rotation axis, and wherein the second end of the push rod is attached to the roll stand, so that, 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 reversal point (U 1) and a second reversal position (U 2), wherein 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 (U 1, U 2) of the translation movement of the roll stand is adjustable, characterized in that the crank drive comprises a through hole having a cross section which is at least in some sections radially symmetric but not rotationally symmetric for receiving the crank pin, wherein the crank pin is designed so that it comprises a base body with a front side and a back side, with a pin section arranged on the front side and with a securing section arranged on the back side, wherein the base body has a cross section which is designed at least in some sections to be complementary to the cross section of the through hole, so that the base body is received in a twist-proof manner and with positive lock in the through hole, wherein the pin section is arranged eccentrically on the base body, so that the pin section can be arranged, by rotating the base body before the introduction into the through hole, at different radial distances from the rotation axis of the crank drive, wherein, on the pin section, the first end of the push rod is attached so that the push rod can be rotated around the longitudinal axis of the pin section,and wherein, on the securing section, a securing element is arranged, so that the crank pin is secured against being pulled out of the through hole. with a feeding clamping carriage for receiving the hollow shell, wherein, during the operation of the mill, the feeding clamping carriage moves between a first (E 1) and a second extreme position (E 2) in such a manner that the hollow shell moves stepwise in the direction toward the tool (2, 3, 4), with a crank drive on a driveshaft, which is rotatably mounted around a rotation axis, with a counterweight attached at a radial distance from the rotation axis to the crank drive, and with a push rod with a first and a second end, wherein the first end of the push rod is rotatably attached on the crank drive around a crank pin at a radial distance from the rotation axis, and wherein the second end of the push rod is attached to the roll stand, so that, 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 reversal point (U 1) and a second reversal position (U 2), wherein 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 (U 1, U 2) of the translation movement of the roll stand is adjustable,
