Description

one

The invention relates to equipment for rolling shops of steel mills and is used in cold rolling mills for strip winding.

The winders are known for coilers, containing a hollow shaft with a pyramidal shaft driven from a ram and placed on it with segments that are radially reciprocating. The water from the segments has a clamping mechanism for the end of the strip, made in the form of a fixed jaw and a movable jaw with a drive for moving it.

In order to increase reliability and increase winding performance in

the walls of the hollow shaft of the drum are made longitudinal channels connecting the drive of the pyramidal shaft with the drive for moving the movable sponge, while the drive for moving the movable sponge is a double acting power cylinder,

. which is rigidly connected to the mobile.

I FIG. 1 shows the proposed reel drum, longitudinal section; in fig. 2 is a cross-sectional view along A-A in FIG. 1. In the hollow shaft 1 there is a cylindrical part of the pyramidal shaft 2- A power cylinder 3 is mounted on the end of the hollow shaft, with the brush 4 connected to the cylindrical part of niramide; tsznogo shaft 2. Segments 6 are fixed on the faces of the pyramidal shaft 5 the outer surfaces of which form the cylindrical surface of the drum. The pyramid shaft 2 can be moved axially with the help of the power cylinder 3, while the segments are moved apart relative to the hollow shaft 2 in the radial direction, as they are connected to it by a detachable yoke 7. In one of the segments 6, two-way power cylinders 8, rods are mounted in the bores which are rigidly connected to the movable sponge 9 of the mechanism for clamping the end of the strip containing the fixed sponge 1O. The oil is supplied to the piston cavities of the power cylinders: grooves 3 and 8 by means of the G1 channels drilled in the walls of the hollow shaft 1. After the strip is fed into the clamping mechanism, the oil is fed into the piston cavity of the power cylinder 3. As a result, the pyramidal shaft 2, moving in the axis direction, pushes the segments6 in the radial direction. At the same time, the oil enters the piston cavities of the power cylinders 8, due to which, under: the visceral sponge 9 approaches the fixed sponge 1O and clamps the end of the strip. At the end of the strip winding on the reel drum, oil is supplied to the rod end of the cylinders 3 and 8. As a result, the pyramidal shaft 2 returns to its original position, the drum collapses, and the movable sponge 9 moves away from the fixed sponge 10, freeing the end of the strip that was previously clamped. Regulating fluid pressure in power; cylinders, create the required force to clamp the strip, providing technological tension without winding a few turns on the winder drum, as well as reliably unclenching the end of the strip for trouble-free, - The invention of the winder drum containing a hollow shaft with a pyramidal shaft placed in it from the power cylinder , on which are mounted with the possibility of radial reciprocating movement of the segments, while in one of the segments; there is a clamping mechanism for the end of the strip, made in the form of a fixed A sponge and a movable sponge with a drive for its movement, characterized in that, in order to increase reliability and increase productivity, longitudinal channels are provided in the walls of the roller shaft connecting the pi-drive; ramidal shaft with a displacement drive (1 sponge), the moving sponge drive ne-i is made in the form of a double action power cylinder, the rod of which is rigidly connected to the movable sponge.
