Fig. 3 shows a schematic view of the crank mechanism of a cold pilger mill. The pair of roll dies is installed in the saddle housing. The rotation of the drive motor is transmitted to induce the reciprocating motion of the saddle via the connecting rod by a crank shaft mechanism.The palmer rolling mill has a rolling stand (1) and a flywheel (10) on a drive shaft which is supported around a rotating axis (18) in a rotating manner. A driving rod (6) is provided with two ends (16,17). The former end of the driving rod is fixed in a radial distance (7) from the rotating axis at the flywheel. A drive motor (9) is a torque motor.

A cold pilger rolling tool for producing internally ribbed tubes uses a cold pilger step rolling process in a rolling stand that is movable back and forth in a direction of rolling and has rolls of a tapered design. The rolls of the stand roll along a material with an alternating direction of rotation. The tool includes a cold pilger rolling mandrel which tapers.Journal of Materials Processing Technology, 34 (1992) 325-332 325 Elsevier Mathematical model of tube cold rolling in pilger mill J.Osika and W.Libura University of Mining and Metallurgy, al.Mickiewicza 30, Krakow, Poland Abstract The paper presents computer simulation results of force parameter investigations (rolling pressure, axial force in tube) for cold rolling in pilger mill.

Carbon Steel Tube Cold Rolling Process Mill Machinery. Steel pipe rolling machines are periodical rolling mills, the work frame and mill rolls do reciprocating motion under the drive of crank-link mechanism.
