Description

The invention relates to metallurgy, and more specifically to continuous casting machines.

A device for cutting gas blanks in a continuous casting plant is known.

The device is a cutting carriage, on the axles of the travel wheels of which the workpiece supporting rollers are mounted. The carriage with the cutter during cutting cuts with the workpiece by means of an upper pressure roller, which is also associated with a rotation drive, in order to return the carriage to its original position for cutting. The guide in this case is directly the workpiece.

The main disadvantage of the device is that, at the cantilever arrangement of the cutter, the structure does not provide reliable support for the end of the cut piece, which limits its possibilities for cutting, for example, slabs with a section that requires an increase in the length of the cutting zone. In addition, the device does not move the gas cutting machine without engaging the workpiece.

The aim of the invention is to expand the assortment of the cut blanks by providing support for the cut ends throughout the cutting area.

The goal is achieved by the fact that gas cutting (MHR) guiding machines are made commensurate with the pitch of the rollers and mounted on the body of the roller table, while the device is equipped with means installed to brake the rollers in the extreme working position of the machine in the gap between the rollers and simultaneously braking of driving wheels of a live roll.

The device for cutting and transporting blanks of the machine for continuous casting of metals consists of a movable roller table 1 moving along guide rails 2 s.

drive 3 and brake 4 with rollers 5 installed on it with drive 6 and brakes 7. Limit switch 8 is installed on the frame of the roll table.

The gas cutting machine 9 is moved along the guides 10, which are mounted either on the frame of the roller table and are made of a length commensurate with the pitch of the rollers (Fig. 1) or of a stationary length, commensurate with the maximum MGR stroke (Fig. 2).

MGR is equipped with a gripping mechanism 11, drive supports 12 with cutters 13 and a limit switch 14. MGR is moved to its initial position to start cutting from the drive 15. Further transportation of the cut piece 16 is performed by the receiving live rolls 17..

The device works as follows.

When a cut is sent to the continuously moving workpiece 1, the gripping mechanism 11 is triggered, the MHR 9 in its initial position to start the cut engages with the workpiece 16 and begins to move along with it,

From the same signal, the drive supports 12c with the cutters 13 are set at the start of the cut to the edge of the workpiece 16 and cut. The movable roller table 1 is kept in its initial position by the brake 4. The supporting rollers 5 are disengaged and freely rotate.

In the case of cutting a small section of the workpiece, when the distance between the rollers is sufficient to produce cutting of the workpiece, MHR, reached the extreme position in the interval between the rollers 5 of the roller table by the signal from the calipers 12, returns to its original position for the production of a new cycle.

In the case of cutting the workpiece 16 of the maximum cross section of MHR 9, reached the extreme position, in the interval between the rollers 5 of the roller table 1 at the signal of the limit switch 14 stops and the movable roller table 1 is released from the brake 4.

At the same time, the supporting rollers 5 are braked by the brake 7, and due to the force of friction between them and the moving workpiece 16, the roller table begins to move along the guides 2 together with the cut workpiece 16 and MHR 9.

At the end of the process of cutting the workpiece 16 from the calipers 12, a signal is sent to

disengagement of the gripping mechanism 11 MGR 9 with the workpiece, rastormazhivaki roller 5 and the inclusion, if necessary, of the drive 3 of the roller table 1.

When the rollers 5 are rotated, the cut billet 16 moves to the transport roller 1 due to the frictional forces between the rotating rollers 5 and it and returns to its original position.

MHR returns to its original position from actuator 15, regardless of the roller table. Thus, the device for cutting and transporting blanks of the machine for continuous casting of metals greatly expands the range of sections of the cut blanks.

by providing support for the cut blanks throughout the entire cutting area.

The use of the proposed device in comparison with a complex of equipment of a similar purpose, for example,

for a 2-strand caster at the Cherepovets Metro Works, it will reduce its weight from 90 tons to 40 tons. In addition, equipment maintenance costs are reduced.
