At outlet of sleeve revolution number of rolls is increased up to 45 - 50. Tubes are rolled in pilger mill at elongation degree μ = 3.0 - 5.0. Invention provides possibility for making high quality hot deformed tubes of large and mean diameters from corrosion resistant hard-to-form steels and alloys in tube rolling aggregates with pilger mills.
Rolling on the pilger mills is considered as one of the most effective manufacturing process in the case of tube production. ... MECHANISM 3.0 GEOMETRICAL MODEL OF ECCENTRIC SHAFT The eccentric shaft of the pilger mill was modeled using UNI GRAPHICS NX 7.5.
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.
rolling mill into a lab-scale pilger mill, which required designing pilger tooling and rolls that contained multiple pilgering grooves and designing a servo-driven feed mechanism. Upon assembling and checking out the system, initial pilgering runs were completed.

Cold rolling of tubes in pilger mills is a cyclical process that is commonly used in manufacturing of tubes made of hardly deformable alloys. In the classic solution,, the rolling stand is mobile and moves to-and-fro, and the rollers move with the stand, while turning in opposite directions.A circular groove is cut in the roller, so that in the entry plane, the groove …

The conversion of the rolling mill to a pilger mill consisted of removing the mechanical linkages that connected the gear motors to the roll dies. The pilger mill system was designed to use index- able servo motors that are connected to the large drive rolls directly. This design allows for more flexibility in the degree and speed of die rotation.
