Description

one

BACKGROUND OF THE INVENTION The invention relates to a device for straightening rolled products.

A hyperboloid roller of a straightening machine is known, which is placed in supports and consists of three drive and feed parts of the same length.

The main disadvantage of the famous roll nakoy quality edits.

In the proposed roll, its extreme components are installed with the possibility of rotation on the pins fixed on the middle part of the roll and are made in the form of eccentric washers and support rings arranged on them. In this case, each eccentric washer is pivotally connected to the support ring by means of a bolt, and each supporting ring is made driven by a gear stage located in the eccentric washer with an intermediate wheel and a gear wheel rigidly connected with a pin fixed on the middle part of the roll .

FIG. 1 shows two opposite straightening shafts, front view;

in fig. 2 - roll in section; in fig. 3 is the same as in FIG. 1, side view; in fig. 4 - roll, section A-A of FIG. 3; in fig. 5yrivots, support rolls.

The longitudinal axes of the protruding hyperbol oid rolls 1 and 2 are opposite to each other and at an angle to the path of the processed product 3

In the machine in question, the lower roll 2 is divided into three parts of approximately equal length 4, 5, 6, with both end parts 4 and 6 rotatably mounted on the trunnions 7 attached to the roll part 5. The drive parts 4 and 6 of the roll consist essentially of rotatably mounted eccentric washers 8, 9 of the support plates 10 and 11 rotating on rolling bearings 12-15 around the centers of the drive parts of the roll. Each eccentric washer 8 and 9 are rigidly bolted to the disks 16 and 17, in which the fingers 18 and 19 are rigidly mounted.

On the supplied with the fingers of the fingers 18 and 19 are installed rotating bolts 2 O

and 21 pivotally connected to the roll supports 22. In this way, it is possible to turn the eccentric washers 8 and 9 and fix them in the installed position, as well as the ability to accurately install the support rings 10, 11, providing the desired direction of the workpiece 3 with different diameters.

In order to reliably exclude friction of the products being processed on the support rings 10, 11, the latter are made driving for this purpose. Each eccentric washer is made of two parts 23 and 24 connected with. using spacer bolts in such a way that between parts of eccentric washers it was possible to install 25 gears 26 and 27 on the shaft.

In part 23, an axis 28 is provided on which the intermediate wheel 29 can rotate. With this gear, the gear wheel 27 and the gear wheel 30, which do not rotate on the trunnion 7 of the middle part 5 of the roll, are meshed; the rotation of the latter in the direction of the arrow A.

The cogwheels of the support rings 10 and 11 also rotate in the direction of the left arrow A. The drive of the straightening roller 1 ensures that it rotates in the direction of arrow B, whereby the workpiece moves in the direction of arrow B.

Claims (3)

1. A hyperboloid roller of correct masin, placed in supports and consisting of three drive and non-drive parts of the same length, which is also so that, in order to improve the quality of editing and improve performance ,. roll, the extreme components of the roll are mounted rotatably on the pins fixed to the middle part of the roll, in the form of eccentric shields and support rings arranged on them. 2. Roller according to claim 1, characterized in that each eccentric washer is connected to the support ring by means of a bolt. 3. Roll on PP. 1 and 2, differing from that, with the NTO, each support ring is driven by means of a gear stage in an eccentric plate with a precision wheel and a gear wheel rigidly connected to a pin fixed on the middle part of the roll .
