Description

Technical Field

[0001] The present invention relates to the technical field of rolling rolls, and more specifically, to a rolling roll cooling device. Background Art

[0002] A rolling roll is an indispensable cylindrical tool in the rolling process. It is mainly used to apply pressure to various materials, such as metals, plastics, etc., to change their shapes, dimensions or physical properties. In the steel rolling and other industrial production processes, the rolling roll plays a crucial role, and its functions and roles cannot be replaced.

[0003] According to the patent document: CN111097801A, a circular rolling roll cooling device disclosed includes a fixed seat, an inlet valve seat is arranged on the fixed seat, the inlet valve seat is connected to the lower end of an arc-shaped spray pipe, and a spray head is arranged at the upper end of the arc-shaped spray pipe; a high-pressure pipe is arranged in the arc-shaped spray pipe, and a circular nozzle and a strip-shaped nozzle are arranged on the side of the arc-shaped spray pipe facing the circular rolling roll, and the circular nozzle is communicated with the high-pressure pipe; the strip-shaped nozzle is communicated with the arc-shaped spray pipe; the circular nozzle and the strip-shaped nozzle are arranged at intervals. The advantages of the present invention are: a reasonable cooling scheme is adopted. Firstly, the circular rolling roll is preliminarily cooled by the spray head to avoid too fast cooling speed, then the high-pressure circular nozzle directly acts on the groove of the circular rolling roll with a higher temperature to ensure the cooling speed, and further ensure the hardness of the groove of the circular rolling roll, and then the uniform cooling by the strip-shaped nozzle makes the circular rolling roll be reasonably cooled, ensuring the rolling quality.

[0004] During the long-term use of the rolling roll, especially in a high-temperature and high-pressure working environment, its surface temperature will rise sharply, which will not only affect the service life of the rolling roll, but also may have an adverse impact on the quality of the rolled products. Currently, it is usually necessary to continuously spray water on the surface of the rolling roll for cooling. However, due to the high surface temperature of the rolling roll, if the water flow sprayed by the nozzle is directly used for cooling, it often leads to uneven cooling, over-cooling in some areas, and still overheating in some areas, thus affecting the overall performance of the rolling roll and the quality of the rolled products. Moreover, the cooling water is generally directly sprayed from the nozzle onto the surface of the rolling roll, and the water flow directly sprayed on the surface of the rolling roll may also cause erosion to the surface of the rolling roll, and over time, it will damage the surface structure of the rolling roll, further shortening the service life of the rolling roll. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides a roll cooling device. The technical problem to be solved by the present invention is that due to the high surface temperature of the roll, if the water flow sprayed by the nozzle is directly used to cool it, it often leads to uneven cooling, over-cooling in some areas, while still overheating in some areas, thus affecting the overall performance of the roll and the quality of the rolled products. Moreover, the cooling water is generally directly sprayed from the nozzle onto the roll surface, and the water flow directly sprayed on the roll surface may also cause erosion to the roll surface.

[0036] When the roll needs to be cooled, first, the staff place the roll on the top of the positioning plate 26 on the inner wall of the cooling chamber 1 by means of a forklift or other handling tools. Then, the double-acting hydraulic push rod 29 is started. The double-acting hydraulic push rod 29 pushes the two expanding and contracting blocks 211 to move in opposite directions. The two expanding and contracting blocks 211 drive the left and right groups of rotating rods 212 and the second rotating rod 213 to rotate, so that the four columnar rotating blocks 210 rotate on the inner walls of the four sides of the positioning plate 26. At the same time, the columnar rotating blocks 210 drive the positioning rotating rod 214 and the positioning vertical rod 215 to move, clamping and fixing the left and right sides of the roll. After the fixing is completed, the hydraulic push rod 23 is started. The hydraulic push rod 23 pushes the push plate 24 to move upward. The push plate 24 drives the connecting block 25, the positioning plate 26, and the roll fixed on the positioning plate 26 to move upward, moving the roll to align with the positioning grooves provided on the inner sides of the two lifting positioning plates 3315. Then, the gas control box 31 is started. The gas control box 31 conveys gas to the pneumatic push rod 3314 through the air pipe 32. After receiving the gas, the pneumatic push rod 3314 pushes the V-shaped rotating rod 3313 to rotate. The V-shaped rotating rod 3313 drives the push-pull shaft 3311 to slide on the inner side of the guide cross bar 3310. At the same time, the push-pull shaft 3311 drives the columnar push-pull cross bar 3312 and the inverted U-shaped push-pull plate 338 to move. The inverted U-shaped push-pull plate 338 drives the positioning V-shaped rotating rod 336 to rotate on the front and rear sides of the columnar cross bar connecting vertical rod 334. The rotation of the positioning V-shaped rotating rod 336 drives the bottom of the lifting positioning plate 3315 to slide inward on the outer wall of the columnar cross bar 333, thereby clamping both sides of the roll;

[0037] After the roll is fixed, start the second hydraulic push rod 419. When the second hydraulic push rod 419 starts, it pulls the push block 418 to move downward. As the push block 418 moves downward, it drives the two V-shaped rotating rods 417 to rotate around the V-shaped rotating rod hinge block 415 as the axis. As a result, the sides of the two V-shaped rotating rods 417 that are away from each other pull the two columnar push rods 4110 to move upward. When the two columnar push rods 4110 move upward, they drive the two groups of columnar lifting vertical rods 4114, the L-shaped lifting rods 4115, the lifting vertical rod connecting rods 4116, and the lifting vertical rods 4117 at their bottoms to pull the two lifting and positioning mechanisms 33 and the rolls fixed inside them to move upward until the rolls are close to the bottom of the top plate 411, so that the rolls are close to the four atomizing water spray plates 423, which is convenient for the atomizing water spray plates 423 to spray onto the roll surface faster to cool the roll. When the whole roll rises, the columnar push rod 4110 moves upward and drives the push and pull vertical rod 4111 at the bottom to pull the double hinge block 4112 to rotate. As a result, the two double hinge blocks 4112 pull the two atomizing water spray plate pulling blocks 424, so that the left and right groups of atomizing water spray plates 423 rotate on the inner wall of the hinge block 413, and the left and right groups of atomizing water spray plates 423 form a downward inclined angle. The water spray nozzles provided at the bottoms of the two groups of atomizing water spray plates 423 are relatively inclined. At this time, the water storage tank 421 conveys water to the inner walls of the atomizing water spray plates 423 through the water pipe 422. The atomizing water spray plates 423 atomize the water source and spray it out from the water spray nozzles to form misty water droplets. And because the water spray nozzles of the two groups of atomizing water spray plates 423 are relatively inclined, the sprayed water mist forms an intersecting state, thereby increasing the contact area between the water mist and the roll surface and improving the cooling efficiency. At the same time, the atomizing water spray method can reduce the waste of water resources compared with direct water spraying and avoid water droplets accumulating on the roll surface and affecting the cooling effect. The whole cooling device is ingeniously designed, easy to operate, and has a high degree of automation, and can realize the rapid, efficient, and uniform cooling of the roll, greatly improving the production efficiency and product quality.

[0038] Working principle of the present invention: When the roll needs to be cooled, first, the staff place the roll on the top of the positioning plate 26 on the inner wall of the cooling chamber 1 with the help of a forklift or other handling tools. Then, the bidirectional hydraulic push rod 29 is started. The bidirectional hydraulic push rod 29 pushes the two expansion and contraction blocks 211 to move in opposite directions. The two expansion and contraction blocks 211 drive the left and right groups of rotating rods 212 and the second rotating rod 213 to rotate, so that the four columnar rotating blocks 210 rotate on the inner walls of the four sides of the positioning plate 26. At the same time, the columnar rotating blocks 210 drive the positioning rotating rod 214 and the positioning vertical rod 215 to move, clamping and fixing the left and right sides of the roll. After the fixing is completed, the hydraulic push rod 23 is started. The hydraulic push rod 23 pushes the push plate 24 to move upward. The push plate 24 drives the connecting block 25, the positioning plate 26 and the roll fixed on the positioning plate 26 to move upward, moving the roll to align with the positioning grooves opened on the inner sides of the two lifting positioning plates 3315. Then, the gas control box 31 is started. The gas control box 31 conveys gas to the pneumatic push rod 3314 through the air pipe 32. After receiving the gas, the pneumatic push rod 3314 pushes the V-shaped rotating rod 3313 to rotate. The V-shaped rotating rod 3313 drives the push-pull shaft 3311 to slide inside the guiding cross bar 3310. At the same time, the push-pull shaft 3311 drives the columnar push-pull cross bar 3312 and the inverted U-shaped push-pull plate 338 to move. The inverted U-shaped push-pull plate 338 drives the positioning V-shaped rotating rod 336 to rotate on the front and rear sides of the columnar cross bar connecting vertical rod 334. The rotation of the positioning V-shaped rotating rod 336 drives the bottom to drive the lifting positioning plate 3315 to slide inward on the outer wall of the columnar cross bar 333, thereby clamping both sides of the roll. After the roll is fixed, the second hydraulic push rod 419 is started. The second hydraulic push rod 419 is started to pull the push block 418 to move downward. The downward movement of the push block 418 drives the two V-shaped rotating rods 417 to rotate around the V-shaped rotating rod hinge block 415 as the axis, so that the mutually separated sides of the two V-shaped rotating rods 417 pull the two columnar push-pull rods 4110 to move upward. When the two columnar push-pull rods 4110 move upward, they drive the two groups of columnar lifting vertical rods 4114 and the L-shaped lifting rods 4115, the lifting vertical rod connecting rod 4116, and the lifting vertical rod 4117 at their bottoms to pull the two lifting positioning mechanisms 33 and the roll fixed inside them to move upward until the roll is close to the bottom of the top plate 411, so that the roll is close to the four atomizing water spraying plates 423, facilitating the atomizing water spraying plates 423 to spray onto the surface of the roll faster to cool the roll. When the whole roll rises, the columnar push-pull rod 4110 moves upward and at the same time drives the push-pull vertical rod 4111 at the bottom to pull the bidirectional hinge block 4112 to rotate, so that the two bidirectional hinge blocks 4112 pull the two atomizing water spraying plate pulling blocks 424, causing the left and right groups of atomizing water spraying plates 423 to rotate inside the hinge block 413, so that the left and right groups of atomizing water spraying plates 423 form a downward inclined angle, and the water spraying ports provided at the bottoms of the two groups of atomizing water spraying plates 423 are inclined relatively.At this time, the water storage tank 421 conveys water source to the inner wall of the atomizing water spraying plate 423 through the water pipe 422. The atomizing water spraying plate 423 atomizes the water source and sprays it out from the water spraying ports, forming mist-like water droplets. Since the water spraying ports of the two groups of atomizing water spraying plates 423 are inclined relatively, the water mist sprayed out forms a crossed state, thereby increasing the contact area between the water mist and the surface of the rolling mill roll.
