Description

In continuous mills for rolling strips and wide sheets, vertical drive shafts, the so-called edgers, are placed. Edgers are self-sufficient machines that are very bulky, complex and therefore expensive both in manufacturing and in manufacturing.

The present invention aims at eliminating the use of these complex machines with the simplest device in the form of two vertical idle rolls installed on the output path of the car, but performed by us, their same functions as the drive edgers. The fact is that during the rolling process, the average gripping angle is about half the initial gripping angle and therefore rolling, when leaving the shafts, can develop the same pressure force that is required to pull it into rolls during rolling. This excess head is used to idle for idle rolls. Most of the rolling coming out of the horizontal drive rolls will rotate the vertical shafts with its excess head and, thus, will be crimped from the sides. Theoretically, the magnitude of this reduction can be with the same angle of capture as on the horizontal drive rolls. By itself

It is understood that, in order to eliminate possible slippage of rolled metal in the throat of the drive rolls, it should be given a stretch in the idle rolls, somewhat less than in the drive rolls.

In FIG. 1 shows schematically the proposed mill as viewed from above; FIG. 2-section ABCD of FIG. one; FIG. 3 is a view along arrow B of FIG. 2

Two rolling beams 7- / with longitudinal grooves are attached to the rolling beds into which the tailings of the housing 2-2 of roller bearings 3-3 are laid. In the bearings, id single vertical rolls 4-4. Beams 7-7 are fixed to the rolling beds with bolts 5-5. Roller bearing housings 2-4 are bolted together between bolts 6-6. The distance between the beams is regulated by shims 7-7, and the distance between the liners and therefore between the vertical rolls is adjusted by shims 8-8. The position of the beams 7-7 and together with the bearings with vertical rollers 4-4 is adjusted in the vertical direction with wedges 9-9. The bearing housings 2-2 with their dovetail tails are freely in the slots of the beams 7-7,

therefore, they can be moved together with the vertical rollers at any time and placed against any caliber of horizontal drive shafts. Their movement is made by rotating the screws 10-10 through the nuts set in the tails of the bodies 2-2. For the correct direction of rolling from the driven horizontal rolls to the idle vertical shafts, the // - 11 wiring and lines 12-12 are inserted. The upper wiring 77 is suspended by the counter-load 13 and rests on the upper shaft and the upper beam 7, and the lower wiring // rests freely on the lower shaft and on the lower beam /; lines 12-12 are laid into the grooves of the beams 1- / and pressed against the bearing housings 2-2. When you move the vertical rolls to a position opposite to another gauge, they are rearranged,

of course, the wiring // - // and the ruler 72-12 to the intended caliber.

The advantage of the proposed design is the elimination of the drive ejector — a separately complex, cumbersome and expensive machine by attaching the idle vertical rolls to the beds of the working drive shafts.
