(54) MECHANIZED LINE FOR CUTTING SHEET ROCKS

one

The invention relates to gas cutting, in particular to the design of a mechanized line for cutting sheet metal.

The known mechanized line for cutting sheet metal, containing the gas cutting machines mounted on the base and moving along the guides, cutting tables for placing the tables, feed and returning roller tables arranged parallel to the guide, lifting devices for cutting tables installed on the base under the gas cutting machines, self-propelled carts with support rollers mounted on them, moved along rail tracks mounted perpendicular to the roller tables 11.

The disadvantage of the line is that self-propelled carriages, located on rail tracks, are installed outside the working areas of gas cutting machines. This increases the distance and time of transportation of spreading tables with sheets between technological positions, which reduces the performance of the line.

The purpose of the invention is to increase productivity by reducing

inter-operation time, i.e. reducing the distance to transport the cutting tables.

This goal is achieved by the fact that in a mechanized line for cutting sheet metal, containing gas cutting machines mounted on the base and transported along guides, cutting tables for

10 placement of sheets, feed and return roller conveyors arranged parallel to the guides, lifting: devices for cutting tables installed on the base under the gas cutting machines, self-propelled carriages with supporting rollers mounted on them moving along relays mounted on perpendicular rolls, reaches those ,

20 that the base is equipped with racks on which guides for gas cutting machines are mounted and whose height exceeds the height of self-propelled carts with support rollers, while in self-propelled carts

25 two slots are made for passage in them (the rollers of the feeding roller table.

Fig. 1 shows a schematic of the line, front view, (the container for the cut out L11 items is not shown); in fig. 2 - then

30, top view; on fig.Z - section

A-L in Fig.1; figure 4 - view B in figure 2.

The mechanized line for cutting sheet metal contains guides 1 mounted on racks 2, and gas-cutting machines 3-5 are mounted on the guides 1. Cutting tables 6 are designed to be placed on them (sheets to be processed (two cutting tables are shown CONDITIONALLY in the drawings.) Under each of the gas-cutting machines 3-5, lifting devices, respectively, 7–9, are mounted on the base, and a feeding roller is installed between the guides 1 10 for cutting tables B. The return roller conveyor 11 is installed outside the rails 1 also parallel to them. In the working areas of the last gas cutting machines 3-5, rail tracks 12 and 13 are located perpendicular to roller tables 10 and 11, self-propelled trolleys 14 and 15 with supporting rollers 16 mounted on them are installed, while self-propelled trolleys 14 and 15 are located along one common axis 17 and 18, respectively, with lifting devices 7 and 8. Table height 2 exceeds the height of self-propelled trolleys with support rollers 16 .

In the self-propelled carts 14 and 15, slots 19 are made coaxially with the rollers 20 of the conveyor roller 10 located at the tracks 12 and 13. The lines also include. Load-lifting device 21 (for example, semi-gantry electromagnetic crane) for sorting and unloading the cut parts from the self-propelled carriage 15 into the container 22. The rollers 20 of the feeding roller table 10 are made lifting, for which they are mounted on power cylinders 2D.

Lini works as follows. The rolling sheet to be cut into parts is loaded onto the cutting table 6 located on the rollers 16 of the self-propelled trolley 14. Thereafter, the self-propelled trolley 14 is fed along the track 12 under the gas-cutting machine 3, while the rollers 20 of the conveyor roller 10 are lowered to the lowest position by means of power cylinders 23, ensuring unimpeded passage over them of the storage table. The cart 14 is stopped in such a way that the cutting table 6 is positioned above the rollers 20, the role of: Ganges;

If the cutting table 6 with the sheet is to be supplied to the gas-cutting machine 3, the lifting device 7 is activated, by which the cutting table b is removed from the trolley 14 and lifted to the working body of the machine 3. In case the cutting table 6 is to be supplied to; machines 4 or 5, rollers

20 are lifted to the uppermost position so that they take on the cutting table 6 with carts 14 and move the cutting table under the corresponding machine 4 or 5 along the roller table 10, and then lift it to the working position with the lifting device 8 or 9. At the same time roller table 10 is released for the next cutting line. The self-propelled trolley 14, which is freed from the spreading: cutting table 6, is returned along the rail track 12 to the load.

Cutting sheet metal into parts is carried out using gas cutting machines 3-5, moving along guide rails 1 mounted on racks 2. After the operation of cutting the sheet is cut, the cutting table 6 is lowered by means of a lifting device 7-9 onto the feed roller table 10, and then the roller table is moved under the gas cutting machine 5 to the rollers 20, which are in a neutral position. The self-propelled carriage 15 is moved along the rail track 13 under the gas-cutting machine 5 and introduced under the cutting table 6, for which the pre-rollers 20 with the table Ivl located on them are raised to the extreme upper position. When this lifting rollers 20 are included in the slots 19 of the trolley 15.

After that, the rollers 20 are lowered on the power cylinders 23 to the lowest position, as a result of which the cutting table is placed on the rollers 16 of the trolley 15. The self-propelled trolley 15 with the cutting table on it is moved along the rail track 13 and stopped in that position, with which the transverse axes of the rollers 16 coincide with the axis of the return roll table 11. With the help of a lifting device 21, the cut-out parts from the cutting table 6 are sorted and unloaded into the container 22.

After finishing the sorting of parts, the releasing cutting table 6 is moved along the return roller table 11 from the trolley 15 to the trolley 14 for loading with a new sheet.

This invention makes it possible to reduce the labor intensity of manufacturing parts by reducing the labor intensity of transport operations, reducing the number of maintenance personnel and reducing the loading and unloading positions and the possibility of servicing them by the same performers, simplifying line management.
