Description

t

The invention relates to pressure treatment of metals, in particular, equipment for cutting and can be used in industry in the lines of rolling mills.

A device for cutting rolled products containing volatile drum shears and movable rolling guide wiring is known. The drum knives include two synchronously rotating drums, each with one knife mounted on the basis of the drums. The movable guide wiring is an articulated tube, by changing the position of which it is possible to change the direction of movement of the rolled metal. With this design, you can trim the ends of the strip and cut it into lengths

In the practice of rolling mills, there are instances when, in connection with boring, there is a need for cutting the rolled metal leaving the roughing group of the mill. In this case, the scabbard, working continuously, completely cuts the cut for the drum's turn.

The pieces of rental are randomly located on the cleaning conveyor around

cutting, which leads to forced shutdowns of the latter and loss of productivity, on the other hand, such a cut-off, being overall scrap metal, can be used in steel-smelting workshops only after packaging in the pile-driving workshop, i.e. with additional technical and economic costs.

A device for cutting rolled products containing two drums associated with a rotating drive and carrying knives and streams interacting with one another is known (moving 15 rolled products, the knives on each drum form two groups, and kx the length is part of the length of the drum forming part as well as the rotary Submission wiring.

However, this device also does not provide for cutting the car with the broom in pieces having a drum circumference.

In order to expand technological capabilities, the creek of each drum is located between groups that have a different number of knives.

Figure 1 shows the device, a general view; figure 2 - section aa on 30 figure 1.

The device contains two drums 1 and 2, associated with a rotating drive and supporting knives 3 and 4, 5 and 6, which interact with each other, and a brook 7 for moving the rolling stock and turning feed wires 8. The knives 3-6 have a length of the lengths of the drum and forms two groups 3, 5 and 4, 6. 7 is located between the goat groups 3 and 5, 4 and 6, the number of knives in groups 3, 4 is not equal to the number of knives in groups 5 and 6. In the case of cutting the front end Groups 3, 4 will have one knife each. For cutting into small pieces in the case of a latch and can be set depending on the required length, for example, four knives, knife 4 can be located both in the same plane as knife b, and in different ones. By setting a different number of knives in groups, a device for cutting to measured lengths can be used.

The device works as follows.

The wire coming out of the rough group of the wire and small-section mill (not shown in the drawing) gets into wiring 8. For trimming the front end of the drill, it is set to position 1. For transmission to the next group of stands, the wiring is turned relative to the hinge 9 to position II. In the cases of pike wiring, the wiring is turned to position III for cutting into small pieces.

The device makes it possible to increase the versatility of the cutting device from the point of view of using it both for trimming the ends of the rolling stock and grinding it.

In addition, short pieces of roll are easily removed by the trimming conveyor, which ensures reliable operation. Further, as scrap metal for steel making, this trimming does not require processing for baling

presses, i.e. is used. without additional costs.
