Недостатком известного устройства вл етс прогиб рабочих валков -в процессепрокатки , привод щий к по влению дефектов геометрии профил проката.A disadvantage of the known device is the deflection of the work rolls in the rolling process, leading to the appearance of defects in the geometry of the rolled stock profile.

Целью изобретени вл етс компенсаци прогиба валков при прокатке.The aim of the invention is to compensate for roll deflection during rolling.

Это достИгаетс тем, что подушки верхнего валка снабжены жестко смонтированньгми на их торцовых поверхност х клинь мй , контактирующими со сферическими выступами планок.This is achieved by the fact that the cushions of the upper roll are fitted with wedges rigidly mounted on their end surfaces that are in contact with the spherical projections of the slats.

/ moves in this direction (screw 7 should be in the lowest position). This is due to the contact of the wedge elements 3 with the spherical protrusions of the plane; to 4, a torque occurs, the moment from the pair of forces PI and P, turning (for this system) counterclockwise. This moment is transmitted through the bearing W to the axis of the work roll.

2. The end of the smallpox of the roll 2 also affects the moment of a pair of forces clockwise, as a result of which the axis is curved downward, creating a bend of the roll 2 in opposite directions. his trough prorkatke. If the resulting bend of the roll 2 is sufficient, the screw 7 is pushed down to Contact with the bottom pad 6, rigidly fixing the entire system. In this way, the position of the work roll pillows can be changed, it is possible to adjust the amount of deflection of the upper valzh, i.e. in this case (when cooked), the depth of the central corrugations. The use of the proposed stand as part of a profile bending mill allows one to eliminate the defect in the undeforming of the central corrugations (due to roll deflection), thereby reducing the setup time of the mill and increasing its productivity. DETAILED DESCRIPTION OF THE INVENTION A two-roller working stand of a rolling mill, mainly molding, contains, and beds, rolls, pillows of work rolls with bearings, fixing strips fixed to the frame and having spherical hubs on their surfaces adjacent to the end surfaces of the pillows. Packs, as well as pressure and adjustment knits, are due to the fact that, in order to compensate for deflections during rolling, the pillows of the upper roll are fitted with wedges rigidly mounted on their cakes, I contact them with spherical projections planak.
