Abstract
Description
Technical Field
[0001] This application relates to the technical field of bar rolling, and specifically, to a conversion guide groove structure at the outlet of the finishing stand for multi-split bars. Background Art
[0002] During the multi-split rolling of bars, in the outlet position of the finishing stand rolling mill, rolling accidents such as top outlet are likely to occur. Since the outlet of the finishing stand and the water-through chute are round pipes, they cannot accommodate a large amount of scrap steel, resulting in the scrap steel winding around the outlet of the finishing stand and the water-through chute or running into the rolling mill to cause roll winding, which is not easy to clean and seriously affects production efficiency.
[0003] In view of this, this application aims to provide a conversion guide groove structure at the outlet of the finishing stand for multi-split bars to better solve the above technical problems. Summary of the Invention
[0004] The purpose of the embodiment of this application is to provide a conversion guide groove structure at the outlet of the finishing stand for multi-split bars, which can solve the technical problem of difficult handling of rolling accidents at the finished product outlet during multi-split rolling.
[0005] The embodiment of this application provides a conversion guide groove structure at the outlet of the finishing stand for multi-split bars, including a fixed support, a plurality of round orifices guide grooves, and a plurality of square orifices guide grooves. The plurality of round orifices guide grooves and the plurality of square orifices guide grooves are arranged on the fixed support in a one-to-one correspondence. The upper part of the square orifice guide groove is open, and the square orifice guide groove is in the shape of a flared mouth with a narrow front and a wide rear.
[0006] Furthermore, the square orifice guide groove is composed of a bottom plate, vertical plates located on both sides of the length direction of the bottom plate, and a pressing plate located at the front upper end of the vertical plates.
[0007] Furthermore, the tail of the bottom plate is bent downward.
[0008] Furthermore, a movable cover plate for preventing steel collision is provided below the pressing plate.
[0009] Furthermore, the pressing plate is trapezoidal, and the pressing plate is welded to the vertical plate.
[0010] Furthermore, the welding angle at the welding position of the pressing plate and the vertical plate is 10°.
[0011] Advantages of the Utility Model
[0012] The export conversion guide groove structure of the multi-split bar finished product rack provided by the utility model includes a fixed bracket, a plurality of round orifices guide grooves and a plurality of square orifices guide grooves. The plurality of round orifices guide grooves and the plurality of square orifices guide grooves are arranged on the fixed bracket in one-to-one correspondence. The upper part of the square orifices guide groove is open, and the square orifices guide groove is in the shape of a flared mouth with a narrow front and a wide rear. The structure of the utility model is simple and reasonable in design. By replacing the original group of round orifices guide grooves with the cooperation of round orifices guide grooves and square orifices guide grooves, after a rolling accident, the scrap steel can be smoothly exported from the open upper part of the square orifices guide groove. And because the square orifices guide groove is in the shape of a flared mouth with a narrow front and a wide rear and the inner cavity is enlarged, it is not easy to be blocked and wound due to the large space of the square orifices guide groove after the scrap steel is exported, thus solving the difficult problems such as the accumulation and winding of scrap steel at the round orifices bridge inlet.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0024] See Figure 1 As shown, the outlet conversion guide groove structure of the multi-split bar finished product rack described in this embodiment includes a fixed bracket 1, a plurality of round mouth guide grooves 2 and a plurality of square mouth guide grooves 3. The plurality of round mouth guide grooves 2 and the plurality of square mouth guide grooves 3 are arranged in one-to-one correspondence on the fixed bracket 1. The upper part of the square mouth guide groove 3 is open, and the square mouth guide groove 3 is in the shape of a flared trumpet with a narrow front and a wide rear.
[0025] The structure of this embodiment is simple and reasonably designed. By replacing the original group of round mouth guide grooves 2 with the cooperation of round mouth guide grooves 2 and square mouth guide grooves 3, after a rolling accident, the scrap steel can be smoothly exported from the open upper part of the square mouth guide groove 3. And because the square mouth guide groove 3 is in the shape of a flared trumpet with a narrow front and a wide rear, the inner cavity is enlarged, and it is not easy to be blocked and wound after the scrap steel is exported due to the large space of the square mouth guide groove 3, thus solving the problem that it is difficult to handle the accumulation and winding of scrap steel at the round mouth bridge inlet.
[0026] In this embodiment, the fixed bracket 1 serves to position the round orifice guide groove 2 and the square orifice guide groove 3. The outlet hole shape of the round orifice guide groove 2 needs to be set to be smaller than the inlet of the water-piercing device to ensure that the rolled piece can enter the water-piercing equipment.
[0027] In some embodiments, the square orifice guide groove 3 is composed of a bottom plate 31, vertical plates 32 located on both sides of the bottom plate 31 in the length direction, and a pressing plate 33 located at the front end of the vertical plates 32.
[0028] Specifically, the tail of the bottom plate 31 is bent downward.
[0029] Specifically, a movable cover plate for preventing steel impact is provided below the pressing plate 33.
[0030] In this embodiment, the structural setting of the square orifice guide groove 3 is specifically shown. The bottom plate 31, the vertical plates 32, and the pressing plate 33 are all made of steel plates. The movable cover plate is arranged below the pressing plate 33 to prevent steel impact. When a rolling accident occurs at the outlet of the finishing stand, the scrap steel can push open the pressed movable cover plate above and be smoothly exported. In this embodiment, by adopting a square orifice cross bridge, after a rolling accident, only the scrap steel needs to be cut to smoothly take out the scrap steel, greatly shortening the accident handling difficulty and time.
[0031] In some specific examples, referring to Figure 2 As shown, taking four-split as an example, the bottom plate 31 of the square orifice guide groove 3 is made of 30mm 16Mn steel plate, 775*560mm, with the tail bent; the vertical plates 32 are made of 20mm 45# steel plate, 60*100*776mm, with a straight section of 575mm; the trapezoidal pressing plate 33 is made of 20mm steel plate, 40*60*100mm, and the welding angle with the horizontal line is 10°. The distance between each small cross bridge at the outlet is 135mm, the inlet is 136mm, the inlet opening is 115mm, and the outlet opening is 40mm. By passing through the round-square conversion guide groove, the defect that the traditional round orifice guide groove 2 is prone to scrap steel accumulation is solved, the accident handling time is shortened, and the labor intensity of employees is reduced.
[0032] In some embodiments, the pressing plate 33 is trapezoidal, and the pressing plate 33 is welded to the vertical plate 32.
[0033] Specifically, the welding angle at the welding position of the pressing plate 33 and the vertical plate 32 is 10°.
[0034] In this embodiment, the structural setting and connection method of the pressing plate 33 are specifically shown. Its structure is simple, the structural stability is good, and at the same time, its welding angle is set to be 10° with the horizontal line, which has a certain guiding property when the rolled piece crosses the bridge, and has strong practicability.
[0035] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
