ROLLER CENTERING UNIT Russian patent published in 2017 - IPC B21B25/02 

FIELD: metallurgy.

SUBSTANCE: roller centering unit contains a stand 1, in which there are four rollers 2 at an angle of 2π/N relative to each other in the plane perpendicular to the centering axis. The rollers 2 are connected to power cylinders 4 through the axes of their rotation 3. Increasing the service life of the centering rollers and improving the quality of the products by avoiding slippage thereof is ensured by the fact that the power cylinders 4 are installed in the stand 1, the working surface of the rollers 2 is made with a spherical radius R, the center of the sphere O of the working surface of the rollers 2 is located on the axis 3 of their rotation, of the axis 3 of the rotation of the rollers 2 in a plane perpendicular to the centering axis, are offset from this axis by a value of c, and the axis 3 of rotation of the rollers 2 in the plane of the centering axis is deviated from the perpendicular to this axis by an angle α.

EFFECT: expansion of technological capabilities.
