摘要： Pilger rolling mill for working a hollow into a tube has a first roll stand mounted linearly moveable in a direction of motion. Translational motion of the roll stand causes rotational motion of the drive gear due to the cogging of the drive gear with the gear rack and, hence, also rotational motion of the roller arranged on the shaft of the drive gear and rotational motion of the other one of the two rollers in the opposite direction. Roll stand is connected with a crank drive and rotational motion of a motor drive is transformed into an oscillating translational motion of the roll stand by a connecting rod. Gear rack holder allows adjustment of the pilger rolling mill with respect to tube diameters of finished rolled tubes by arranging the first roll stand exchangeable by a second roll stand with a second dimension being different from the first dimension.

摘要： A cold pilger rolling mill for forming a tube shell to a tube includes a feed clamping carriage for receiving the tube shell and with a drive that is arranged to move the feed clamping carriage such that during the operation of the cold pilger rolling mill the tube shell moves step-by-step in the direction of the tool. A control and a sensor detect a measure of a force exerted during the operation of the cold pilger rolling mill by the tool onto the tube shell, and wherein the control is connected to the drive and the sensor. The control is arranged to regulate, during the operation of the cold pilger rolling mill, the step length per advance step with which the drive moves the feed clamping carriage to the tool as a function of the measure for the force, which measure is detected by the sensor.

摘要： A pilger rolling mill with a roll stand moves linearly back and forth along a movement direction and includes a crank mechanism having a rotatably supported crankshaft with a crank pin and push rod. A first end of the push rod is pivotably fastened to the crank pin and a second end is pivotably fastened to the roll stand, so that during operation of the pilger rolling mill a rotary movement of the crankshaft is converted into an oscillating movement of the roll stand along the movement direction. A compensation shaft is rotatably supported about an axis of rotation and includes a distribution of mass that is not rotationally symmetrical relative to its axis of rotation and a counter-mass. The crankshaft and the compensation shaft are connected to one another by a transmission so that a rotation of the crankshaft leads to a rotation of the compensation shaft.
