Description

BACKGROUND OF THE INVENTION The invention relates to devices for right-handed rolled strip.

An installation for straightening rolled strip is known, which contains an input servo installed in the technological sequence, a brake servo, a roller correct machine, a device: a tension bar for tension, and an output serlomer.

The aim of the invention is to improve the quality of morals.

This is achieved by the fact that the device for tensioning the lolosa is made in the form of pairs located on the axles above each edge of the strip; the upper and lower rolls are made of two parts, one of which is mounted in bearings with the possibility of Brush, axial direction, and the other part rigidly connected with the axle, with the padv: the upper part of the upper roll is located above the fixed part of the lower roll, the fixed part of which is located under the fixed part of the upper roll, and each roll is provided with an individual drive.

FIG. 1 shows the proposed installation, general view; in fig. 2 - the same, in plan; in fig. 3 shows a section A-A in FIG. 2

The installation contains serially located input serlomer /, brake device 2, lravilno-roli1kovsky device

3, the main device 4 and the output serpomer 5.

On the axis 6, there is an upper roll of the driving device 4 (see FIG. 3), worn out

composite, namely: one part 7 of the roll is located on the bearings 8, fixed by gaskets 9 and nuts 10 and, therefore, movable relative to the axis 6; the other part 1} of the roll is rigidly connected to the axle. On

the movable 7 stationary // parts of the roll are open toothed crowns 2 and 13, fixed with pins 14. On the axis 15 there is a lower roll, also worn out composite, and its movable part 16 is located against the fixed part // of the upper roll, and the fixed part 17 is opposite movable 7 parts of the barrel top roll. Toothed rims 18 and 19 are laid on the movable 16 and fixed 17 parts of the roll.

When the axis of the upper roll rotates, the torque component through part 11, which is rigidly connected with the axis, and the gear rims 13 and 18 are transferred to the movable part 16 of the lower roll, while this movement does not damage the movable part 7 of the upper roll and the stationary part / 7 of the lower roll. When the axis of the lower roll rotates, the torque through the fixed part / 7 is transmitted in a similar way to the motive part of the upper roll 7 and is not transferred to the movable

part 16 of the lower roll and the fixed part // upper shaft; ka.

Thus, 1 rolls of a heavy-duty device, concave with composite, while simultaneously applying to the top / it and the same roll: M different torque values, especially особ 1 Ы when interacting with the strip, create polos on each edge, force, causing a non-uniform width deformation of the strip.

During the movement of the poloyu through the set: the input serpomer 1 measures the initial crescent of the strip both in magnitude and in sign. The required level of tension on the strip is the statute of A.vl, which is topped by the torus-force yst | poystvovovM 2. When the plot with the measured; gray, uvnostnost reaches the rollers of the correct-roller facility 3, then the shaft increases in proportion to the measured seriavidnosti of those parts, K01 in the driving device 4, which pull the short edge of the strip, and reduce by that amount the bearing of the other parts of the rollers that pull the long edge.

As a result of a combination of the reverse bending of a strip that occurs in a roller-roller device, with a variable width of the strip (Tension is large at the short edge, it is real (it is: offered by pulling devices, strip lengths of strip edges, t. its direction of seroovidnosti. The quality of the control of crescent forms controls the output serpomer 5.

In the case of construction of the band with a sickle-shaped, close to zero, both pairs of interacting parts of the rolls of the driving device develop a decisive force (effort).

In this way, the proposed installation allows the crescent of the strip to be corrected by combining the bending of the strip in the vertical plane with an uneven application of pulling forces along its width.

Subject invention

An installation for continuous straightening of a rolled strip containing an input serpamer installed in a technological sequence, a braking device, a roller correct machine, a device for tensioning the strip, and an output serpomer, characterized in that, in order to improve the quality of the straightening, the device for tensioning the strip made in the form of pairs of axes located above each edge of the strip of the upper and lower rolls, made of two parts, one of which is mounted in bearings for rotation relative to the axis and the other part is rigidly connected with the axis, wherein the movable part of the upper roll is located above the fixed part of the lower roll, the movable part of which is located under the fixed part of the upper roll, and each pair of rolls is provided with an individual drive.
