SU325059A1 - DEVICE FOR TRANSFER OF ROLLERS - Google Patents

Description

In the structures of rolling mills in the transshipped set there are rolls with cushions located only at the service side. During transshipment, the neck 1 of the rolls enters or leaves the inner rings of the support bearings installed in the cushions fixed in the beds, located on the side of the drive of the rolls. This places new demands on the device for handling rolls: installation accuracy and alignment of the rolls with respect to the fixed onore during the transfer.

The proposed device is characterized in that the pivoting arm is made with openings for the transshipment necks of the rolls, in which the stirring wedge and the split sleeves are installed, and is connected to the pivoting mechanism by means of earrings and a hinge.

This allows precisely and quickly installing and turning the rolls in the process of transshipment and simplifying the design of the device.

Wah FIG. 1 shows the device, front view; in fig. 2 - the same general view; in fig. 3 - version of the pivot arm.

The device consists of a carriage 1 mounted on it by a movement actuator 2, for example a hydraulic cylinder, and an installation mechanism 3 and alignment of the rolls during transshipment.

The installation mechanism and alignment contains hand-held lever 4 and the drive 5 of the rotation of the lever. The pivot arm with the axle of the ramp 6 is installed in sub-ports 7 that are attached to the carriage.

The lever is made with holes 8 for transfer necks of 9 rolls 10. The distance between the axes of the holes is equal to the distance meiad by the longitudinal axes of the rolls in the position of the transshipment.

Non-moving wedges //, springs} 2 wedges return and split sleeves L (see Fig. 3) are installed in the holes of the pivot arm.

In another embodiment (see Fig. 1) of the pivot arm in the apertures, sleeve 14 with an internal diameter under the transferring neck 9 of the roll is mounted.

To fix the transfer roll in the pivot arm, a latch 15 is installed, made in the form of a pin, which is included in the ring groove 16 of the roll shake. To prevent the upper roll cushion 17 from turning, the transshipment lever 4 is equipped with a spindle 18, which enters the cushion groove 19.

The actuator 5 for turning the lever is located on the rack 20 and consists of a gearbox 21, on the high-speed shaft of which a wheel is mounted. For adjusting the rolls, a 23 m boom dial 24 is installed. with an earring 26 with articulated gank 27 and axle 28.

The transfer of the rolls is carried out as follows. The device for transferring by means of transfer 2 is brought to the rollers 10 of the rolling mill which are set to the non-reeling position. At the same time, transshipment necks .9 enter into the holes of the rotary lever 4 and the rollers are fixed relative to the lever (see Fig. 3) with a wedge 11, non-moving shaft at the end A, split sleeve 13 and pin 15 or (see Fig. 1) sleeve and pin 15. Then, by turning the actuator 5, the lever 4 with the rollers installed in it is displayed in the direction of the greatest freedom of movement of the rolls, fixed by the arrow 24 and dial 23. The carts, alternating with the rolling line, outputting the rolls from the rolling mill.

When the rolls are filled, the operation is performed in the reverse order.

The proposed device allows transfer rolls both alternately and simultaneously.

A different execution of the rotary lever 4 n. Bleaching it with a number of holes equal to the number of rolls of the rolling mill, discards the transshipment of rolls of any type of rolling mill.

Subject invention

A device for reloading rolls, consisting of a trolley with a non-displacement drive, a mechanism for installing rolls, comprising a rotary lever with a drive and a turn, characterized in that in order to simplify the roll repair and improve the accuracy of the alignment of the rolls in which a moving wedge and split sleeves are installed, and is associated with a novorot mechanism through earrings and sariir.
