Description

The invention relates to the field of rolling production, in particular, to the construction of reel winders.

The purpose of the invention is to increase reliability.

FIG. 1 shows a drum, a general view; FIG. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one.

The drum contains a pyramid shaft 1, an axial displacement drive of the latter (not shown) mounted on shaft 1, segments 2, mounted on the corresponding segment 2 of jaws 3 and 4 for clamping the end of strip 5, a drive of moving jaw 4 in the direction perpendicular to the longitudinal axis of the pyramidal shaft 1, made in the form installed on the segment 2 of the hollow wedge przushki 6, mounted on the pyramidal shaft 1 of the strap 7 with a groove 8, placed in the slide 6 and the groove 8 of the rod 9 with the head 10, and also covering the rod 9 and installed between the heads oh 10 of the rod 9 and the strap 7 of the elastic element 11. The surface 12 of the sponge 4 from the side of the wedge plate olszushki 6 is made beveled. Segments 2 on the shaft

mounted on guides 13. The lip of the drum 30 does not decrease until mics 3 and 4 are connected to each other by means of the guide 14, the sponge 4 and the wedge slider 6 by means of the guide 15, and the slider 6 and segment 2 by the guide 16 .

The drum works as follows.

Before refueling the front end. the strip 5, by means of a drive, drives the pyramidal shaft 1 in the axial direction, forcing the segments 2 to move in the radial direction, reducing the drum diameter to a minimum.

At the same time, using the bar 7, the rod 9 and the elastic element 11, the pyramidal shaft 1 moves the slider 6 in the axial direction. The slider 6 moves the sponge 4 through the guide 15, which moves in the direction perpendicular to the direction of movement of the slider 6, and the sponge 4 is made along the wedge surface. From the axial movement, the sponge 4 is fixed by means of the guide 14 of the jaw 3. Between the jaws 3, 4 there is a gap into which the front end of the strip 5 is set.

The front end of the strip 5 is clamped as follows.

The pyramid shaft 1 moves axially in the opposite direction to the original. The segments 2 move along the pyramidal shaft 1 in the radial direction, forming the maximum diameter of the drum. At the same time, using the strap 7, the pyramid shaft 1 through the rod 9 and the elastic element 11 presses against the slider 6, and the latter in turn moves the sponge 4 to the sponge 3, clamping the front end of the strip 5 between them. 4 and, consequently, the slider, and the course of the pyramidal shaft 1 remains the same, so the elastic element 11 in the slider 6 compensates for the difference of these movements.

When the roll is removed, the pyramid shaft 1 moves in the axial direction, causing the segments 2 to move in the radial direction, reducing the drum diameter to a minimum. At the same time, the elastic element 11 allows the slider 6 and the sponge 4 to remain stationary until dianim. With the appearance of a gap between the roll and the drum, the elastic element 11 moves the slider 6 and the sponge 4, releasing the front end of the band 35, after which The roll is removed from the reel drum.

The technical and economic effect of the implementation of the invention is provided by an increase in reliability compared with the basic object.
