[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Refer to Figure 2 , Figure 3 and Figure 5 , an embodiment provided by the present invention: a temperature control pre-piercing water cooling system for the flying shear outlet section, including a hollow column 1. A cavity 3 is provided inside the hollow column 1. A plurality of holes 11 are equidistantly arranged around the inner bottom of the cavity 3. The left side of the top of the hollow column 1 is communicated with a liquid inlet 4. The bottom end of the liquid inlet 4 penetrates the cavity 3. A micro motor 5 is fixedly connected to the left side of the liquid inlet 4. The output end of the micro motor 5 penetrates the liquid inlet 4 and is fixedly connected to a worm 6. A cross fixing plate 7 is fixedly connected to the inside of the liquid inlet 4. The middle part of the top of the cross fixing plate 7 is rotatably connected to a movable rod 8. A worm gear 9 is fixedly connected to the middle upper part of the outer side of the movable rod 8. The worm gear 9 is meshed with the worm 6. A plurality of sector plates 10 are fixedly connected to the outer side bottom of the movable rod 8. A water pressure sensor 12 is fixedly connected to the front side of the liquid inlet 4. A cleaning mechanism 2 is arranged inside the hollow column 1. The gap sizes on the cross fixing plate 7 respectively match the sizes of the corresponding sector plates 10. The left end of the worm 6 is rotatably connected to the inside right side of the liquid inlet 4;

[0040] Specifically, the water pressure sensor 12 can monitor the pressure of the cooling water entering the hollow column 1. During the cutting process, the stability and uniformity of the cooling water are crucial for ensuring the cutting effect. Therefore, when the water pressure sensor 12 detects fluctuations in the cooling water pressure, it will quickly respond and drive the rotation of the worm 6 through the micro motor 5. The meshing relationship between the worm 6 and the worm wheel 9 causes the worm wheel 9 to rotate accordingly. This rotation is transmitted through the movable rod 8, and the sector plate 10 on the movable rod 8 will rotate accordingly. At this time, the flow rate and pressure of the cooling water can be adjusted by changing the angle between the sector plate 10 and the cross fixing plate 7. This adjustment mechanism ensures the stability of the water pressure, thereby guaranteeing the uniformity of the water flow during the cutting process.

[0041] Refer to Figure 1 and Figure 4 Specifically, the cleaning mechanism 2 includes a hollow cover 201 and an arc-shaped scraper 205. The hollow cover 201 is arranged at the left end of the hollow column 1. The right side inside the hollow cover 201 is rotatably connected with a rotating rod 202. The middle part of the outer side of the rotating rod 202 is fixedly connected with an impeller 203. The left and right sides of the outer wall of the rotating rod 202 are equidistantly and fixedly connected with a plurality of connecting rods 204. One ends of the plurality of connecting rods 204 are respectively fixedly connected with the left and right sides of one end of the corresponding arc-shaped scraper 205. The sizes of the plurality of arc-shaped scrapers 205 are all matched with the internal size of the hollow column 1.

[0042] Specifically, first place the hollow cover 201 at the left end of the hollow column 1, and then limit and fix the hollow cover 201 through the bolt 206 to ensure that it will not loosen or shift during subsequent operations. After completing the above steps, we inject water into the hollow column 1 through the liquid inlet 4. When the water flow enters the hollow column 1, its flow rate just drives the rotation of the impeller 203. This design cleverly utilizes the kinetic energy of the water flow without the need for an additional power source, which is both environmentally friendly and economical. As the impeller 203 rotates, the connecting rod 204 also rotates accordingly. This action further drives the rotation of the arc-shaped scraper 205. The arc-shaped scraper 205 is carefully designed to be able to closely fit the inner wall of the hollow column 1, effectively scraping off the impurities and sediments attached to it. This scraping work not only prevents the inner wall of the hollow column 1 from generating scale, thereby extending the service life of the hollow column 1, but also improves the performance of the entire cooling system.

[0043] Refer to Figure 1 Specifically, a controller 13 is fixedly connected to the middle part of the front side of the hollow column 1. The controller 13 is electrically connected to the micro motor 5 and the water pressure sensor 12 respectively. A protective cover 14 is arranged outside the controller 13, and one side of the protective cover 14 is rotatably connected to the front side of the hollow column 1.

[0044] Specifically, the controller 13 can control the operation of the micro motor 5 and the water pressure sensor 12, and the provided protective cover 14 can protect the controller 13 from being damaged by external factors.

[0045] Referring to Figure 1 , the cleaning mechanism 2 further includes bolts 206. The two bolts 206 are respectively rotatably connected to the front and rear sides of the hollow cover 201, and one end of the bolt 206 sequentially penetrates through the hollow cover 201 and the hollow column 1;

[0046] Specifically, the bolts 206 can limit and fix the hollow cover 201, and can prevent the hollow cover 201 from accidentally falling off during the scraping work.

[0047] Working principle: When using this device, first subject the rolled piece to rough rolling, flying shear of the head and tail, medium rolling, flying shear of the head and tail, pre-splitting and splitting, and then perform pre-water cooling. The rolled piece enters from the left side of the hollow column 1 and then extends out from the right side of the hollow column 1. At this time, connect the external cooling water to the liquid inlet 4, and the cooling water will cool the rolled piece entering the hollow column 1 through the holes 11. At this time, observe the water pressure sensor 12. When the pressure of the cooling water entering the hollow column 1 fluctuates, the micro motor 5 can drive the worm 6 to rotate. Since the worm gear 9 meshes with the worm 6, it will also rotate accordingly, thereby driving the movable rod 8 to rotate. At this time, the sector plate 10 on the movable rod 8 will rotate accordingly, and thus the flow rate and pressure of the cooling water can be adjusted according to the angle change between the sector plate 10 and the cross fixing plate 7, which can ensure the water pressure stability, and thus ensure the uniformity of the water flow during the cutting process, will not affect the cutting effect, can meet the needs of users, and after the cooling work is over, first install the hollow cover 201 at the left end of the hollow column 1, and then the bolts 206 can limit and fix the hollow cover 201. At this time, inject water into the hollow column 1 through the liquid inlet 4, and the impeller 203 will rotate driven by the flow rate of the water flow, and the connecting rod 204 will rotate accordingly, thereby driving the arc-shaped scraper 205 to rotate to scrape the inner wall of the hollow column 1, which can prevent the inner wall of the hollow column 1 from generating scale and reducing the durability of the hollow column 1, thereby improving the practicability of this device.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
