Abstract

A semi-continuous metal casting machine, containing a mechanism for pulling ingots in the vertical direction, a self-propelled trolley moving along gear racks located on the edging frame, a receiving device for dispensing blanks, and a device for repairing trolleys. The device for repairing trolleys is located at the end of the edge of the frame opposite from the direction of delivery of the blanks. The tilting frame and the device for repairing trolleys are made with guides for moving self-propelled trolleys in an amount equal to the number of streams of the machine. In the same amount, the device for repairing trolleys is equipped with retractable segments consisting of additional gear racks that are moved and abutting when extended, like the guides of this device, in gear racks and guides of the edging frame. The utility model allows to simplify the operation of removing self-propelled carts for their repair and maintenance.

Description

The utility model relates to metallurgy, in particular, to the field of semi-continuous casting of steel.

A known machine for semi-continuous casting of metals with the pulling of the ingots in the vertical direction along.with. USSR No. 197877 (publ. 09.06.67). The machine contains a self-propelled carriage, which moves along the guides due to the gear running on a fixed rail by a gear fixed to the carriage drive. The rail and guides are mounted on a canting frame. Seeds are fixed on the trolley, the number of which is equal to the number of streams of the machine. The canting frame, after casting is completed, is rotated 90 ° to dispense blanks from the machine into a receiving device located in a horizontal plane.

The disadvantage of this known machine is the presence of a single drive for pulling workpieces on several streams. Such a drive makes it difficult to service the machine during repairs, since it is necessary to replace the seeds or parts of the drive and the trolley directly on the machine or to replace a large bulky trolley with all the seeds.

From this drawback is free machine for semi-continuous casting of metals according to the patent of the Russian Federation No. 1790469 (publ. 23.01.93). This semi-continuous metal casting machine contains a mechanism for pulling ingots in the vertical direction, consisting of a self-propelled cart moving along gear racks located on the edging frame, a receiving device for dispensing blanks and a device for repairing carts located at the end of the edging frame opposite to the direction of issuing blanks. The tilting frame and the device for repairing trolleys are made with guides for moving several self-propelled trolleys, the number of which is equal to the number of streams.

With this method of repair and maintenance, special mounting devices are used to replace the self-propelled carts, which complicates these operations.

The proposed utility model solves the problem of simplifying the operation of extracting self-propelled carts for their repair and maintenance.

To achieve this technical result in a semi-continuous metal casting machine containing a mechanism for pulling ingots in the vertical direction, a self-propelled trolley moving along gear racks located on the tilting frame, a receiving device for dispensing billets, a device for repairing bogies located in the opposite direction from the issuing of billets the end of the tilting frame, and the tilting frame and the device for repairing trolleys are made with guides for moving self-propelled trolleys in an amount equal to Mr. the number of streams of the machine. In the same amount, the device for repairing trolleys is equipped with retractable segments consisting of additional gear racks that are moved and abutting when extended, like the guides of this device, in gear racks and guides of the edging frame.

Distinctive features of the proposed machine for semi-continuous casting of metals is the supply of the device for repairing trolleys with extendable segments, consisting of additional gear racks, movable and abutting when extended, as well as the guides of this device, in gear racks and guides of the edging frame.

The presence of these signs makes it possible to improve the service conditions of the machine, since bulky mounting devices are not required to send a self-propelled cart to a special repair site. The cart rolls away by itself, moving from the guides of the canting frame to the guides of the sliding segments.

Below is an embodiment of a utility model that does not exclude other options within the formula, with reference to the drawings shown in FIGS. 1-2.

Figure 1 shows a General view of the machine semi-continuous casting of metals;

figure 2 is the same in the vertical direction;

figure 3 is the same, a section along aa;

figure 4 is the same, a section along BB.

The continuous metal casting machine comprises a tilting frame 1, a self-propelled trolley 2 and a device for repairing trolleys 3. The tilting frame can be rotated in the supports 4. The guides 5 are mounted on the frame and gear racks are mounted 6. A seed 7, a pinion gear 8 with a drive are mounted on the self-propelled trolley 9 and support wheels 10. The device for repairing trolleys is equipped with extendable segments 11, consisting of additional gear racks 12, movable and abutting when extended, like the guides 13 of this device, in gear racks 6 and guides 5 canting frames. A drive 14 is provided for tilting the frame. Liquid metal is formed into blanks 15 in the mold 16. The machine also has a device for disengaging the seed from the blank 17 and a receiving device for dispensing the blanks 18.

The machine operates as follows. The metal is poured into molds 16, from where the workpiece 15 is pulled by the seed 7 when the trolley 2 moves along the guides 5. The trolley moves due to the rotation of the gear 8, which is engaged with the rail 6. The gear rotates from the drive 9. After casting, the canting frame 1 by the drive 14 is rotated 90 ° and is installed in a horizontal position. After that, the workpiece 15 moves to the receiving device 18, and the release device 17 separates the seed 7 from the workpiece 15. After that, the workpiece is removed outside the machine with a receiving device (for example, a roller table) 18.

If it is necessary to replace the seed or any part of the drive or trolley, the trolley is replaced. This is achieved as follows. The tilting frame 1 must be installed in a horizontal position. The seed 7 is freed from the workpiece 15. After that, the hydraulic cylinders 19 move the sliding segments 11 all the way into the canting frame 1. There is a docking of additional rails 12 of the sliding segments 11 and the rails 6 of the canting frame 1. The trolley 2 rolls out into the sliding segment 11. In this case, the support wheels 10 trolleys exit from the closed guides 5 of the canting frame 1 into the guides 13 of the extension segment open from above. This allows you to dismantle the trolley 2 up, disengaging its gears. Instead of a faulty trolley, a new trolley is installed, which in reverse order is supplied to the canting frame 1, and the extension segment 11 is rolled back to its original position. As a result, there is the possibility of a gap between the sliding segment 11 and the canting frame 1, which is necessary for installing the canting frame in a vertical position.
