Description

Technical Field

[0001] The utility model relates to the field of flange ring rolling processing, in particular to a water spraying and cooling device for a flange ring rolling machine. Background Art

[0002] After the preliminary forging of the flange steel billet, it is necessary to use a ring rolling machine to perform ring rolling treatment on the steel billet, so that the wall thickness of the ring-shaped steel billet is reduced and the diameter is enlarged, and then the ring-shaped cross-section is gradually formed. During the working process of the ring rolling machine, it is necessary to continuously spray water on the surface of the steel billet. On the one hand, it can cool and shape the steel billet, and on the other hand, it can clean the oxide scale impurities on the surface. This leads to the mixture of the used water and impurities such as oxide scale becoming sewage. These sewage is very easy to splash into the surrounding environment, resulting in a dirty processing environment. At the same time, some sewage is also easy to remain and accumulate inside the ring rolling machine, eroding the components of the ring rolling machine after a long time, reducing the overall service life of the ring rolling machine. Content of the Utility Model

[0003] The purpose of the utility model is to provide a water spraying and cooling device for a flange ring rolling machine, which can solve the technical problems that the sewage formed by cooling is easy to pollute the processing environment and erode the ring rolling machine, realize the unified collection and treatment of sewage, avoid the sewage flowing to the surrounding environment or inside the ring rolling machine, and ensure the cleanliness of the processing environment and the service life of the ring rolling machine.

[0004] In order to achieve the above object, the utility model is realized through the following technical solutions:

[0005] A water spraying and cooling device for a flange ring rolling machine includes a foundation pit. A moving table is slidably connected inside the foundation pit. One end of the moving table is provided with a central shaft. A frame is fixed inside the foundation pit, and the frame is located above the moving table. A rolling roller is rotatably connected to the frame. Connecting rods are symmetrically and rotatably connected to both sides of the frame. A limiting roller is rotatably connected to the connecting rod. A top frame is rotatably connected to the end of the moving table, and one end of the top frame is in contact with the top of the central shaft. A water spraying pipe is provided at a position above the central shaft on the top frame. A plurality of nozzles are communicated and arranged at the bottom of the water spraying pipe. A guardrail is provided on the side of the moving table. Notches are symmetrically provided at positions on both sides of the central shaft on the guardrail. Inclined guide plates are provided at the notches. Through holes are symmetrically provided on both side walls of the foundation pit. The guide plates are slidably connected inside the through holes. Water storage tanks communicated with the through holes are symmetrically provided on both sides of the foundation pit.

[0006] Furthermore, a placing plate is provided on the frame, and a guiding hole is provided on the placing plate. The central shaft is slidably connected inside the guiding hole.

[0007] Furthermore, the water spraying pipe is arc-shaped, and the water spraying pipe is located above the area between the rolling roller and the central shaft.

[0008] Furthermore, a water inlet hole communicating with the through hole is provided on the side wall of the reservoir. A filter rack is provided in the reservoir, and a filter cylinder is provided on the filter rack. The filter cylinder is located below the water inlet hole.

[0009] Furthermore, filter holes are provided at both the bottom and the side of the filter cylinder.

[0010] Furthermore, the top of the filter rack is higher than the top of the reservoir.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the present utility model is in use, the annular billet is sleeved on the central shaft. Then, the lateral sliding of the moving table drives the annular billet to move on the frame until it contacts the rolling rollers on the frame. The connecting rods on both sides are rotated so that the limiting rollers on the connecting rods contact the side surface of the annular billet. During the rotation of the rolling rollers, the moving table drives the central shaft to move towards the rolling rollers, so that the wall thickness of the annular billet gradually decreases and the hole diameter gradually increases during the rotation and rolling process, realizing the rapid forming of the annular billet. At the same time, a top frame is rotatably connected to the end of the moving table, and one end of the top frame contacts the top of the central shaft, thereby restricting the annular billet on the central shaft and avoiding potential safety accidents caused by the annular billet breaking away during the ring rolling process. A water spray pipe is provided at a position above the central shaft on the top frame, and a plurality of nozzles are connected to the bottom of the water spray pipe. Such a structure can use the nozzles to spray water to cool the annular billet between the central shaft and the rolling rollers. Different positions of the annular billet are in contact with the water sprayed by the nozzles during the rotation process of the annular billet, realizing the rapid cooling of each position of the annular billet, effectively removing the oxide scale on the surface, and improving the forming efficiency;

[0013] 2. A guardrail is provided on the side of the moving table to block the flowing of the sewage formed after cooling in all directions. Notches are symmetrically provided on the guardrail at positions on both sides of the central shaft. Inclined guide plates are provided at the notches. Through holes are symmetrically provided on the side wall of the foundation pit. The guide plates are slidably connected in the through holes. Reservoirs communicating with the through holes are symmetrically provided on both sides of the foundation pit. Such a structure enables the sewage to only flow out along the notches, and the sewage flowing out enters the reservoirs on both sides along the guide plates, realizing the unified collection of the sewage, avoiding the sewage flowing into the surrounding environment causing pollution or accumulating inside the ring rolling machine to erode the components, facilitating the centralized treatment of the sewage, ensuring the cleanliness of the processing environment, and ensuring the service life of the ring rolling machine.

Detailed implementation manners

[0020] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0021] Refer to Figure 1 and Figure 2, the present utility model relates to a water spraying and cooling device for a flange ring rolling machine. The main structure includes a foundation pit 1, which is generally dug below the ground. The main components of the ring rolling machine are all arranged in the foundation pit 1. A moving table 2 is slidably connected in the foundation pit 1. The moving table 2 is driven to slide by any existing power structure such as a lead screw slider. One end of the moving table 2 is welded or bolted with a central shaft 3. The preliminarily forged flange billet is sleeved on the central shaft 3 by means of a hoisting structure. By sliding the moving table 2, the flange billet on the central shaft 3 can be moved. A frame 4 is welded or bolted in the foundation pit 1. The frame 4 is located above the moving table 2 and is used to support the flange billet. After the flange billet is sleeved on the central shaft 3, its bottom is located on the frame 4. A rolling roller 5 is rotatably connected to the frame 4 through bearings. The rolling roller 5 is driven to rotate by a motor and is used to drive the rotation of the flange billet after contacting its side surface. The moving table 2 drives the flange billet on the central shaft 3 to move towards the rolling roller 5 until the outer side of the flange billet contacts the rolling roller 5. On both sides of the frame 4, connecting rods 6 are symmetrically rotatably connected through pins or hinges. A limiting roller 7 is rotatably connected to the connecting rod 6 through bearings. The connecting rod 6 is driven to rotate by a cylinder or an electric cylinder. When the rolling roller 5 drives the flange billet to rotate, the moving table 2 drives the central shaft 3 towards the rolling roller 5, thereby expanding the flange billet between the central shaft 3 and the rolling roller 5, reducing its inner wall thickness and enlarging its inner hole diameter, so that the flange billet is quickly formed. During this process, the connecting rods 6 on both sides rotate, so that the limiting rollers 7 at the ends of the connecting rods 6 contact both sides of the flange billet, restricting the rotation position of the flange billet and preventing it from tilting, thus ensuring the accuracy and stability of the flange billet expansion processing. One end of the moving table 2 is rotatably connected to a top frame 8 through a pin or a hinge. One end of the top frame 8 far from the hinge position with the moving table 2 contacts the top of the central shaft 3. The top frame 8 is driven to rotate by a cylinder or an oil cylinder. Such a structure rotates the top frame 8 to open and separate from the central shaft 3 when the flange billet is placed. After the flange billet is placed, the top frame 8 rotates in the opposite direction and contacts the top of the central shaft 3, locking the top of the central shaft 3, thereby preventing the flange billet on the central shaft 3 from detaching during the forging process and ensuring the safety of the expansion processing. A water spraying pipe 9 is arranged at the position of the top frame 8 above the central shaft 3. The water spraying pipe 9 is communicated with an external water supply system. A plurality of nozzles 10 are connected to the bottom of the water spraying pipe 9. During the rotation of the flange billet, the cooling water sprayed by the nozzles 10 is sprayed onto the surface of the flange billet to cool and shape it and remove the oxide scale on the surface. Through the continuous rotation of the flange billet, effective cooling and cleaning operations can be achieved for each position. A guardrail 11 is welded or bolted to the side surface of the moving table 2. The moving table 2 is located below the frame 4. Therefore, the sewage formed by cooling the flange billet on the frame 4 will flow into the lower moving table 2. The side surface is protected by the guardrail 11 to prevent the sewage from flowing everywhere.On the guardrail 11, symmetrically arranged at positions on both sides of the central axis 3 are notches 12, which are the only channels for sewage to flow out. At the notches 12, inclined diversion plates 13 are welded or bolted. On both side walls of the foundation pit 1, symmetrically arranged are through holes 14, and the diversion plates 13 are slidably connected in the through holes 14. Such a structure enables sewage to be discharged from the diversion plates 13 at the notches 12, and the diversion plates 13 are always slidably connected in the through holes 14. Therefore, during the movement of the moving platform 2, it is ensured that the sewage can accurately flow out from the through holes 14. On both sides of the foundation pit 1, symmetrically arranged are water storage tanks 15 communicated with the through holes 14. The setting of the water storage tanks 15 can be used to collect the sewage flowing out from the through holes 14, thereby realizing the unified collection of the sewage formed by cooling, preventing it from flowing into the surrounding environment to cause pollution or accumulating inside the foundation pit 1 to erode the components of the ring rolling mill, improving the convenience of sewage cleaning, and ensuring the cleanliness of the processing environment and the service life of the ring rolling mill.

[0022] Preferably, referring to Figure 4 , fixedly welded or integrally formed on the frame 4 is a placement plate 16. On the placement plate 16, there is a through guiding hole 17, and the central axis 3 is slidably connected in the guiding hole 17. Such a setting enables the bottom of the flange billet to be supported by the placement plate 16 when it is sleeved on the central axis 3. When the central axis 3 moves, it slides in the guiding hole 17, enabling the flange billet on the central axis 3 to move on the placement plate 16, improving the supporting effect on the flange billet, and ensuring the accuracy and stability of the moving ring rolling process.

[0023] Preferably, the water spray pipe 9 is arc-shaped and is located above the area between the rolling roller 5 and the central axis 3. The arc-shaped structure can better adapt to the gradually formed ring billet, enabling the water for cooling to be evenly sprayed onto the flange billet between the central axis 3 and the rolling roller 5, improving the uniformity and efficiency of cooling.

[0024] Preferably, referring to Figure 3 , on the side wall of the water storage tank 15, there is a water inlet hole 18 communicated with the through hole 14. The sewage passes through the through hole 14 and enters the water storage tank 15 from the water inlet hole 18. Inside the water storage tank 15, there is a filter rack 19. The size and shape of the filter rack 19 are adapted to the water storage tank 15. After it is placed inside the water storage tank 15, it contacts the inner wall of the water storage tank 15. On the filter rack 19, there is a filter cylinder 20, and the filter cylinder 20 is located below the water inlet hole 18. Such a structure enables the sewage to flow into the filter cylinder 20 first after flowing in from the water inlet hole 18, and only enters the water storage tank 15 after being filtered by the filter cylinder 20, thereby blocking impurities such as scale in the filter cylinder 20, reducing the difficulty of subsequent sewage treatment, and improving the convenience of subsequent sewage treatment.

[0025] Preferably, filter holes 21 are provided at both the bottom and the side of the filter cartridge 20. Such a setting increases the filtering area, making it difficult for the positions of the filter holes 21 to be blocked, and ensuring the filtering effect under long-term use.

[0026] Preferably, the top of the filter rack 19 is higher than the top of the reservoir 15. After long-term use, such a structure allows operations such as hoisting the filter rack 19 from the outside, so as to take out the filter rack 19 and the filter cartridge 20 from the reservoir 15, and quickly clean impurities such as scale on the filter, improving the convenience of cleaning the filter cartridge 20.

[0027] Working principle: When the present utility model is in use, the ring billet is sleeved on the central shaft 3, and then the transverse sliding of the moving table 2 is used to drive the ring billet to move on the frame 4 until it contacts the rolling rollers 5 on the frame 4. Then, the connecting rods 6 on both sides are rotated so that the limiting rollers 7 on the connecting rods 6 contact the side surface of the ring billet. During the rotation of the rolling rollers 5, the moving table 2 drives the central shaft 3 to move towards the rolling rollers 5, so that the wall thickness of the ring billet gradually decreases and the aperture gradually increases during the rotational rolling process, realizing the rapid forming of the ring billet. At the same time, a top frame 8 is rotatably connected to the end of the moving table 2, and one end of the top frame 8 contacts the top of the central shaft 3, thereby restricting the ring billet on the central shaft 3 and avoiding potential safety accidents caused by the ring billet coming off during the ring rolling process. A water spray pipe 9 is provided at a position above the central shaft 3 on the top frame 8, and a plurality of nozzles 10 are connected to the bottom of the water spray pipe 9 in a communicating manner. Such a structure can use the nozzles 10 to spray water to cool the ring billet between the central shaft 3 and the rolling rollers 5. During the rotation of the ring billet, different positions thereof are in contact with the water sprayed by the nozzles 10, realizing the rapid cooling of various positions of the ring billet, effectively removing the scale on the surface, and improving the forming efficiency; a guardrail 11 is provided on the side of the moving table 2 to block the flowing of the sewage formed after cooling in all directions. At positions on both sides of the central shaft 3 on the guardrail 11, notches 12 are symmetrically provided, and inclined guide plates 13 are provided at the notches 12. Through holes 14 are symmetrically provided on the side walls of the foundation pit 1, and the guide plates 13 are slidably connected in the through holes 14. Reservoirs 15 communicated with the through holes 14 are symmetrically provided on both sides of the foundation pit 1. Such a structure enables the sewage to only flow out along the notches 12, and the sewage flowing out then enters the reservoirs 15 on both sides along the guide plates 13, realizing the unified collection of the sewage, avoiding the sewage flowing into the surrounding environment to cause pollution or accumulating inside the ring rolling machine to erode the components, facilitating the centralized treatment of the sewage, ensuring the cleanliness of the processing environment, and ensuring the service life of the ring rolling machine.
