(54) DEVICE FOR CENTERING THE ROLL

I

The device for centering the roll relates to the field of metal forming and, in particular, can be used in tape-rolling shops.

A device for centering a roll is known, comprising a lifting table, a rod with a probe, and a mechanism for working out a table lift 1.

The disadvantage of this device is that the mechanism for working out the lifting of the table is made in the form of a series of toothed-rack and pinion gears that regulate the height of the lifting of the table. The complicated design of the table lifting mechanism reduces the installation accuracy and leads to frequent breakdowns.

It is also known to have a device for centering a roll comprising a lifting table, a shanta with a probe, a probe movement mechanism and limit switches 2.

The disadvantage of such a device is the complex kinematic coupling of the probe and limit switches, resulting in a loss of time for maintenance and commissioning. In addition, such a device does not have a molset to work together with a tilter, which significantly sums up its application area.

To improve the accuracy of alignment and expand the technological capabilities of the proposed device is equipped with a swivel stand with a console, and shtanga with probe.

the mechanism for moving the probe and limit switches are installed on the console of the rack, and the mechanism for moving the probe is made in the form of a pneumatic cylinder.

FIG. 1 shows a general view of the device;

in fig. 2 is a view along arrow A in FIG. one; on

FIG. 36 is a section along BB in FIG. one.

The device for centering the roll contains a cradle 1 of the turn-off device with the collider 2, the pin 3 on which the roll 4 is installed.

8 is connected with the hydraulic cylinder 10 of its vertical movement, and through the sleeve 11 and the lever 12 is connected with the hydraulic cylinder 13 of the rotation of the rack. Limit switches 14 and 15 interact with blinders placed on

lever 12. Limit switches 16 and 17 are located on the console 7. Lifting table 18 serves to lift the roll 4.

The device works as follows. The console 7 by the cylinder 13 is rotated to

the anvil, with the probe 5 located above the middle of the roll. After this, the console 10 is lowered by the cylinder 10, and the probe 5, connected to the rod of the cylinder 6, presses the bent outer coil, after which the probe begins

mix up and act on the limit switch 16, which gives an impulse to stop the cylinder 10 and lift the table 18. The roll is lifted by the table until the probe moves further to the limit switch 17, which stops the lifting of the table. In this position, the axis of the roll coincides with the axis of the pin of the turner, which is led out of the roll, and the stand 8 with the console 7 is rotated to its original position, making room for turning the subsequent roll.

The placement of the probe, limit switches, and the pneumatic cylinder for moving the probe on the turntable extends the technological capabilities of the device and provides an increase in the roll installation accuracy.
