Description

, FIG.

The invention relates to the processing of metals by pressure, in particular to the processing of strips in the cold state.

A device for preventing unraveling of rolls is known, comprising a pivotally mounted swing frame with a rotatable mount mounted on a flexible frame with a drive mechanism, an optional 1V eV cripple arm, mounted on a single arm with a single arm mounted on a pivot arm, the second arm of the two-arm arm pivotally coupled to a pivot drive of the bending roller.

A device is also known that is equipped with an additional pressure roller with a drive for its movement and a bending roller made by a drive and kinematically connected to the support roller.

The disadvantage of these devices is the inability to use them in a wide range of thicknesses of the strips of the processed rolls, because to overcome the forces arising from double bending with increasing strip thickness, it requires the use of a high power drive, which causes an increase in weight, dimensions of the device and design complexity . In addition, unreliable refueling strip in the throat of the winder.

The purpose of the invention is to expand technological capabilities by expanding the range of processed strips in thickness.

This goal is achieved by the fact that in the device for preventing fluffing of rolls of a strip comprising two drive and one non-drive bending rollers, two of which are permanently mounted on the holder, and the third is located on an element movable relative to the holder, the rotation drive of the drive bending rollers and the movement drive a movable element placed on the holder, as well as a pinch roller with a mechanism for moving it, the holder is made in the form of a fixed beam with a through guide hole and sides brackets, the movable element is made in the form of a crawler traverse placed in the guide hole with a cantilever end section, a non-bending bending roller is fixed on the cantilever cantilever section, both drive rollers are mounted on the holder, and the device is equipped with a filling roller mounted on the cradle above the non-driving bending roller with a gap.

Fig. 1 shows a device for preventing fluffing of strip rolls in an initial position for a task in the throat of a drum of a winder;

figure 2 - the same in working position at the time of folding the strip.

A device for preventing fluffing of strip rolls includes a holder 1 made in the form of a fixed crosshead with a through hole and side brackets, two driven bending rollers 2 with a rotation drive mounted on the holder, a spider 3 with a drive for moving it 4, on the cantilever

a portion of which a non-driving bending roller 5 is installed, and a filling roller 6 is above it with a gap. The creeper 3 is located in the through guide hole of the crosshead. In addition, a clamping roller 9 is mounted on the holder and is fixed on a two-arm lever 7 having a displacement drive 8.

The device is mounted directly above the drum of the winding device along its axis.

A device for preventing the swelling of strip rolls works as follows,

The creeper 3 of the actuator 4 is lowered into

the lower position (Fig. 1), in which the bending roller 5 and the refueling roller b are set at a level that ensures the unhindered passage of the strip 11 into the throat of the drum 10 when the task is between the rollers with a certain clearance.

Next, the task of the strip 11 in the throat of the drum 10 of the winding device and the winding of the strip on the drum is performed, and as the diameter of the roll increases during winding and the strip is raised, the crawler 3 rises with it synchronously.

Knowing the length of the strip 11, which must be subjected to deformation, before the end of winding, the moment is determined

beginning to slow down the speed of winding the strip to the filling level. The pressure roller 9 with the drive 8 is lowered onto the roll, and the non-drive bending roller 3 is translated into the working position (figure 2), while

the strip receives the necessary bending deformation and exits the bending rolls 2, 3, has a bending radius less than the radius of the wound roll. This deformation and causes a tight winding of the last turns

roll and keeping it from fluffing.

At the end of the winding, the roll is ready to be removed from the drum and transported, without tying it around the perimeter with tape. After removing the roll from the drum, the spider 3 lowers to the lower position and the cycle repeats.

The absence of double bending with this bending roller operation scheme reduces energy consumption and makes it possible to use the device in a wide range of strip thickness and diameters of processed rolls while maintaining the effect, because the bending radius can be changed by the amount of deformation of the strip. The technical and economic efficiency of the invention is achieved by increasing the productivity of slitting units (time due to the elimination of the binding operation is used for technological purposes), saving the binding tape and expanding the range of processed rolls.
