Description

Filling the strip into the slot between the rollers 6 and the ring 9. By moving the ring 9 in the direction of the set of boiler rollers, due to the opposite taper, the gap between them is reduced. When moving in the opposite direction, the clearance increases. Shaft 3 rotates continuously. Each rolling cycle is continuous. By reducing the duration of the pauses between the rolling of individual sections of the strip and their complete absence during the rolling of each individual section, the productivity increases. 1 il.

I

The invention relates to rolling production and can be used for the transverse rolling of thin strips.

The aim of the invention is to increase productivity by continuously carrying out each rolling cycle.

The drawing shows a working stand for transverse rolling of metal strips.

The working stand consists of a bed 1, where the drive shaft 3 is mounted on the bearing supports 2, on which the guide sleeve 5 fixed to rotation with the aid of the hub 4 is seated, the set of conical rollers b mounted on the latter in the separator 7 rests on the latter.

The rolled strip And is filled between a set of tapered rollers 6 and a deforming wedge made in the form of (ring 9 with an internal taper opposite to the taper of the set of rollers 6). The ring 9 is installed in a cylindrical holder 10 made of antifriction material that has the ability to axially move in 1, using a screw-screw drive 11.

The cage works as follows. When filling the strip into the working stand, the strip is fed from the left winder to the slot formed between the set of the tapered roller 6 and the ring 9 (the yoke 10 with the ring 9 mounted on it takes the far right position), and is loaded on the right winder. In the drawing, both winders are conventionally not shown. Then, the rotational drive of the drive shaft 3 with the guide sleeve 5 mounted on it is turned on, which rotates and rotates, due to the frictional forces between the rollers 6 and the holder 5, a set of tapered rollers 6. Moving the mechanisms 10 with the mechanisms 11 to ring 9 is used to reduce the strip 8, filled between the set of tapered rollers 6 and the tapered ring 9. The compression of the strip is controlled by axial movement using mechanisms 11, ring 9 and the yoke 10, due to the opposite taper of the set Ikov rings 6 and 9, there is a change of the gap between the latter. In order to reduce wear on the surfaces ot, the sleeve 10 is made of an anti-friction material. After rolling the strip 8 to the desired size, the clip 1-0 and the ring 9 are retracted from the set of tapered rollers 6, until the gap between the latter is formed sufficiently to allow the strip to move freely through the cage so that the non-deformed section of the strip leaves the deformation zone. At the same time, the drive shaft 3, the support collar 5 and the set of tapered rollers 6 continuously rotate, thereby reducing the dynamic loads on the drive associated with acceleration and braking of the latter, as well as the pause time is reduced. After performing the above, all operations are repeated for the refilled portion of the strip until the entire roll is rolled.
