Description

The invention relates to the mechanization of the loading and unloading of heating furnaces and can be used in pipe-rolling shops of metallurgical plants.

The purpose of the invention is to increase productivity by reducing the gap between the diamagnetic sheet and the inductors.

1 shows a device for loading and unloading ring furnaces, general view; figure 2 - section aa in fig „1; on fig.Z - section bb in figure 1.

The device contains a movable, you- 15 working side gaps

The carriage 1, filled in the form of a two-support monobalk, 1, equipped with running wheels 2 and 3, in the upper part of which a conductive sheet 4 of a diamagnetic material, HanpiiMep of aluminum alloy, is vertically fixed. On both sides of the sheet 4, two inductors of a 5 liter cervical engine 6 located on the overpass 7 are installed symmetrically. From below to the carriage 1, a swiveling trunk 9, fitted with a tong clamp 10, is hinged on the hinge 8. in the upper position. On the trunk 9 there is a pneumatic cylinder 12 clamping the workpieces with a tong tong 10, On either side of the carriage 1 behind the running wheel 3 on the opposite side from the tong 10, the trunk 9 is mounted on independently rotating rollers 13 pressure rollers 14. Each lever 13 is kinematically connected to a spring spring 15 , and the spring 15 - with the loading screw 16. Odin of the pinch rollers 14 kinema

Practically, by means of a gear, it is connected with a pulse sensor 17, which provides control over the movement of the carriage 1 (along the way and speed). The rollers 14 are in contact with the lower directions of the usdmi 18 and, thanks to the spring springs 15, press the wheels 3 to the upper guides 19 of the overpass 7 and fix the carriage 1 in a vertical plane.

In this case, due to the fact that, on one side of the carriage, the running wheels 2 and 3 are equipped with double-flange covers covering both the sliding and the upper guides 18 and 19, lateral displacement of the diamagnetic sheet 4 is eliminated. The latter in the monobalk slot is installed vertically and fastened to it through the fastener 20 (for example, bolt-nut) by means of two sheets 21 with rhombic corrugation. One of the sheets is rigidly fastened to the msnobalk (for example, welded), and the second by means of the sleeves 22 secures the diamagnetic sheet to the first rhombic sheet, and the surface with rhombic corrugation of the sheets is installed inwards to the diamagnetic sheet 4.

In the upper part, the diamagnetic sheet 4 is placed in the guides 23, which are attached to the inductors 5 of the engine, and between the diamagnetic sheet 4 and the inductors 5 are provided

To reduce the deformation caused by heating in the process of operation of the MAEM, the diamagnetic sheet is made with through grooves 24 located at the level of the active working zone of the inductors 5 with step t, which is calculated depending on the drive power and the mode of operation of the machine.

The optimal length of the diamagnetic sheet 4 and the carriage are chosen to be equal to the maximum working stroke of the machine 1, uv (1 lrg for the length of the inductor and doubled, the emergency brake stop Ij (right: Q and

The device works as follows.

Trunk 9 after urslade the next billet on the live rolls sews {horizontal position), with the sponge tick-held jaws 10 opened.

With the inclusion of the pneumatic cylinder 1 1 in the forward stroke, trunk 9 ;. rotated relative to the hinge 8, inclined, non-working, position. The linear motor 6 is switched on, its inductors 5 come into operation, which create a magnetic tractive force 5 and, acting on the RD, a magnetic sheet 4, inform the latter and, accordingly, the carriage 1 in the working stroke section, the working speed.

At the end of the working stroke, the engine 0 6 is turned on in opposition to the movement of the carriage I, it brakes until it stops and is held in the final position.

With the activation of the pneumatic cylinder 11 in reverse, the trunk 9 returns 5 to a working horizontal position (the gripping jaws 10 are opened), and with the pneumatic cylinder 12 12 being turned on, the gripping jaws 10 are retracted to capture the heated billet from the bottom of the ring furnace. With the pneumatic cylinder 1I turned off, the trunk 9 with the clamped workpiece, turning relative to the hinge 8, takes the upper inclined non-working position. In this position, the trunk 9, the engine 6 is turned on for the reverse stroke and the carriage 1, having made a working stroke, moves to the position

for unloading the workpiece, where from the pneu-fou inducers installed in the cylinder 11, the trunk 9 returns to the horizontal working position, and from the pneumatic cylinder 12 unclamps the grips 10 and the heated workpiece is placed on the roller table for its further transportation to the pipe-rolling unit Then the cycle repeats.

The length of the working stroke, depending on the layout of the blanks at the hearth of the annular furnace, is a variable value, therefore the path of the machine is programmed according to the number of pulses of the sensor 17 pulses

The proposed device for loading and unloading blanks from an annular furnace, as compared with the known ones, ensures stable machine speed and.
