Abstract

The invention relates to rolling production and can be used for rolling high-grade varietal profiles. The purpose of the invention is to improve the accuracy of rolling by eliminating the misalignment of additional bearing supports with rolling rollers. The radial loads caused by the imbalance of the spindles are transferred to the additional self-aligning bearing supports 7. The supports 7 receive only the radial load. The supports 7 are freely mounted on the drive ends of the rolls. Then they are fixed in this position on the fixed housing 8 with bolts 10. The pressure mechanisms 3 and the adjustment devices 9 operate synchronously. 2 Il.

The invention relates to rolling production and can be used for rolling high-grade varietal profiles. The purpose of the invention is to increase the accuracy of rolling by eliminating the misalignment of the additional bearing supports with the rolls.

FIG. 1 shows a rolling mill, general view; in fig. 2 - rolling stand from the drive side, general view.

The rolling mill contains a rolling stand with two mutually perpendicular pairs of rolls 1 and 2 with pressure mechanisms 3 and axial adjustment mechanisms 4, with the pairs of rolls arranged along the rolling axis at a small distance one relative to the other in detachable bed 5. Drive ends 6 rolls are equipped with additional bearings 7 with cushions installed in a stationary housing 8 with adjusting devices 9, fixed on the stand of the cage with bolts 10, and connected to the drive 11 of the rolling mill. The additional bearings 7 with cushions are fixed to the housing 8 by bolts 12.

Rolling mill works as follows.

During the rolling process, the work steps from the spindles of the mill drive are transmitted to the drive ends of the 6 rolls. The radial loads caused by the imbalance of the spindles are transferred to additional self-aligning bearing supports 7, which take only the radial load and which, in order to maintain alignment, are freely mounted on the drive ends of the rolls and then fixed in this position on the fixed housing 8 by bolts 10. The housing 8 is mounted on detachable frame 5 stands and fastened to it with bolts 12. The coaxiality of the additional supports 7 and work rolls 2 during the radial adjustment of the latter is achieved by agreement The movement of the screws of the pressure mechanism 3 and adjusting devices 9.

Claims (1)

Invention Formula A rolling mill containing a working stand with two mutually perpendicular pairs of rolls with a small distance between the pairs of rolls and pressure devices placed in the frame, additional bearings in the pillows placed in a separate housing with an adjusting device and drive, characterized in that higher accuracy 1 and 2 are perceived as radial, rolled by eliminating misalignment and the axial load from the metal being rolled. The radial movement of the rolls during adjustment of the gauges is carried out by the pressing mechanisms 3, and about the axial movement of the rolls by the mechanisms 4 of the axial adjustment. Twisting rolls with additional bearings in the pillows, additional bearings with pillows mounted on the drive ends of the rolled rollers, and their separate housing with an adjusting device mounted on the cage bed. rolls with additional bearings in the pillows, additional bearings with pillows mounted on the drive ends of the rolled rollers, and their separate housing with an adjusting device mounted on the cage bed.
