Abstract
A cold pilger rolling mill which has a roll stand that can be moved back and forth, a pair of cranks each having a crankpin, a pair of thrust rods that connect the roll stand to the crankpins, and centrifugal counterweights connected to the cranks so as to be eccentric to the rotational axis of the crank to at least partially balance inertial mass. The centrifugal weights are staggered by 180 degrees to the connection point of the respective thrust rod and crank and each crank and its associated counterweights forms a submechanism. The submechanisms are arranged in a mirror image around a vertical plane which intersects a roll axis. A common drive is provided for driving the roll stand. The drive includes a drive shaft that connects the submechanisms to one another and is located beneath a rolling plane. The submechanisms have rotational axes that run horizontally parallel to one another, and the drive turns the cranks in opposite directions.
