Description

Technical Field

[0001] This utility model relates to the field of round billet casting and processing technology, and more specifically, it relates to an annular spray manifold for uniform cooling of round billets. Background Technology

[0002] Round billet cooling is a key process for controlling billet quality in round billet casting. It refers to the process in which, after the molten metal initially solidifies in a circular crystallizer to form a billet shell, a directional and uniform cooling medium, such as atomized water or a water-air mixture, is applied in the secondary cooling zone of a continuous cooling system to allow the round billet to gradually solidify from the surface to the core, ultimately obtaining a round billet product with uniform structure, no cracks, and stable dimensions.

[0003] Existing secondary cooling spray devices mostly adopt a circumferentially fixed nozzle structure, and their spray angle cannot be adjusted synchronously along the axial direction of the round billet. Therefore, it is difficult to adapt to the cooling coverage requirements of round billets of different diameters. For example, when producing small-diameter round billets, if the nozzle spray angle is too large and fails to narrow in time, the sprayed cooling medium will be dispersed and wasted, resulting in uneven cooling. When processing large-diameter round billets, if the spray angle is not widened accordingly, it cannot be ensured that the cooling medium can completely cover the surface of the round billet, thus creating cooling dead zones and causing local insufficient cooling.

[0004] Therefore, in order to solve the above problems, we propose an annular spray manifold for uniform cooling of round blanks. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides the following technical solution:

[0006] An annular spray manifold for uniform cooling of round billets includes an annular main pipe, with multiple spray mechanisms spaced apart around the center of the annular main pipe. Each spray mechanism includes a nozzle. A connecting branch pipe is provided on one side of the nozzle on the annular main pipe. The nozzle is rotatably disposed at the water outlet end of the connecting branch pipe. The spray mechanism also includes an adjustment component disposed at one end of the nozzle. The adjustment component can apply force to one end of the nozzle, thereby driving the nozzle to rotate around the water outlet end of the connecting branch pipe to adjust the spray angle.

[0007] Furthermore, the nozzles are arranged radially along the annular main pipe and are evenly distributed.

[0008] Furthermore, a connection hole is provided on the side wall of the nozzle, the end of the connecting branch pipe extends into the connection hole, and limit blocks are respectively provided on both sides of the connection hole. The side wall of the nozzle is rotatably disposed in the annular gap between the two limit blocks, thereby realizing the rotatable connection between the nozzle and the connecting branch pipe.

[0009] Furthermore, the adjustment assembly includes a pressure rod hinged to one end of the nozzle, a first drive block located at the top of the pressure rod, and a second drive block that cooperates with the first drive block to apply pressure to the pressure rod. When the second drive block passes along the top wall of the first drive block, it squeezes the pressure rod located at the bottom of the first drive block to move, causing the pressure rod to push the nozzle to rotate, thereby realizing the adjustment of the nozzle spray angle.

[0010] Furthermore, the second driving block abuts against the first driving block, and the top wall of the first driving block is an inclined surface.

[0011] Furthermore, a connecting seat is provided on the side of the annular main pipe near the pressure rod, a baffle is formed in the middle of the connecting seat, the bottom end of the pressure rod passes through the baffle and the bottom wall of the connecting seat, a limit ring is fixed on the outer wall of the pressure rod, a return spring is sleeved on the outer wall of the pressure rod, the two ends of the return spring are respectively located between the limit ring and the bottom wall of the connecting seat, and linear protrusions are also formed on both sides of the pressure rod to prevent axial deflection.

[0012] Furthermore, a connecting seat is provided on the side of the annular main pipe near the pressure rod, and a movable ring is provided on the side of the annular main pipe near the second driving block. The second driving block is fixedly connected to the movable ring and can rotate around the center of the annular main pipe under the drive of the movable ring.

[0013] Furthermore, a drive mechanism is provided on one side of the movable ring to push it to rotate and change its rotation direction.

[0014] Furthermore, the driving mechanism includes a toothed plate fixed to the surface of the movable ring and extending along the direction of the movable ring, and a driving gear meshing with the toothed plate. A mounting seat is provided between the driving gear and the annular main tube, and the transmission shaft of the driving gear is rotatably connected to the mounting seat.

[0015] Furthermore, when multiple sets of the annular main pipes are provided, each annular main pipe is distributed in parallel along the axial direction, and each annular main pipe can be connected to the others by a connector.

[0016] In summary, this utility model has the following beneficial effects:

[0017] This invention, by setting a rotatable nozzle and a corresponding adjustment component, allows for flexible adjustment of the spray angle of the cooling medium according to the different diameters of the round blank. When processing small-diameter round blanks, the drive mechanism drives the movable ring to rotate, and the second drive block presses the pressure rod at the bottom of the first drive block. The pressure rod begins to move, driving the nozzle to rotate around the water outlet end of the connecting branch pipe, narrowing the spray angle, avoiding the dispersion and waste of cooling medium, and ensuring uniform cooling. When processing large-diameter round blanks, the drive mechanism rotates the movable ring in the opposite direction, and the return spring resets the pressure rod. The nozzle rotates to widen the spray angle, ensuring that the cooling medium can completely cover the surface of the round blank, eliminating cooling dead zones, and improving the quality and efficiency of round blank cooling.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Please see the appendix Figure 1-7 An annular spray manifold for uniform cooling of round blanks includes an annular main pipe 1 with a water inlet port for connecting to an external cooling medium supply pipe. The annular main pipe 1 has a flow channel for the cooling medium to pass through. Multiple spray mechanisms 2 are distributed at intervals around the center of the annular main pipe 1. The size and specifications of the annular main pipe 1 and the number of spray mechanisms 2 can be determined according to actual usage requirements.

[0031] The spraying mechanism 2 includes a nozzle 201, which is a cylindrical structure. One end of the nozzle has a water outlet with multiple small spray holes. The cooling medium is sprayed out in a spray form through the spray holes. The annular main pipe 1 is provided with a connecting branch pipe 5 on one side of the nozzle 201. The connecting branch pipe 5 is L-shaped and one end is connected to the internal flow channel of the annular main pipe 1. The nozzle 201 is rotatably set at the water outlet of the other end of the connecting branch pipe 5. The cooling medium flows from the annular main pipe 1 into the connecting branch pipe 5 and is then sprayed out through the nozzle 201.

[0032] like Figure 4 , 5 As shown, the spraying mechanism 2 also includes an adjustment component disposed at one end of the nozzle 201. The adjustment component can apply force to one end of the nozzle 201, thereby driving the nozzle 201 to rotate around the water outlet end of the connecting branch pipe 5 to adjust the spray angle. When facing a small-diameter round billet, the spray direction of all the nozzles 201 on the annular main pipe 1 is more concentrated towards the center line of the round billet, reducing the fan-shaped range and radiation area of ​​the spray coverage, and avoiding the cooling medium being sprayed to the outside of the round billet and wasting it. When encountering a large-diameter round billet, the spray angle is widened, allowing the spray direction of all the nozzles 201 to appropriately diffuse outward, expanding the spray coverage range, and ensuring that the cooling medium can completely cover the circumferential surface of the round billet without any cooling dead corners.

[0033] Each group of nozzles 201 is arranged radially along the annular main pipe 1, with its spray end pointing towards the center of the annular main pipe 1. Each group of nozzles 201 is distributed at equal intervals around the center of the annular main pipe 1 to ensure uniform cooling of the circumferential surface of the round blank.

[0034] like Figure 7 As shown, a connection hole is provided on the side wall of the nozzle 201. The horizontal branch end of the connecting branch pipe 5 extends into the connection hole, and limit blocks are respectively provided on both sides of the connection hole, so that the side wall of the nozzle 201 is rotatably set in the annular gap between the two limit blocks, thereby realizing the rotational connection between the nozzle 201 and the connecting branch pipe 5, and preventing the nozzle 201 from falling off the connecting branch pipe 5 through the limiting effect of the limit blocks.

[0035] The adjustment assembly includes a pressure rod 207 hinged to one end of the nozzle 201, a first drive block 204 located at the top of the pressure rod 207, and a second drive block 206 cooperating with the first drive block 204 to apply pressure to the pressure rod 207. The pressure rod 207 is connected to the nozzle 201 and can rotate the nozzle 201 around the connection fulcrum with the connecting branch pipe 5 by applying pressure to one end, thereby realizing the directional swing of its spray end and ultimately realizing the adjustment of the spray angle of the cooling medium.

[0036] The bottom end of the second drive block 206 abuts against the top end of the first drive block 204. The top wall of the first drive block 204 is an inclined surface, and protrusions extend vertically upward from both ends of the inclined surface, thereby restricting the range of motion of the second drive block 206 and preventing it from sliding off the top wall of the first drive block 204. When the second drive block 206 passes along the lower side to the higher side of the top wall of the first drive block 204, it can press the pressure rod 207 located at the bottom of the first drive block 204 to move, thereby causing the pressure rod 207 to apply pressure to one end of the nozzle 201, thereby adjusting the spray angle of the nozzle 201.

[0037] A connecting seat 202 is provided on the side of the annular main pipe 1 near the pressure rod 207. The connecting seat 202 has an L-shaped structure, and its top is fixedly connected to the annular main pipe 1. A baffle is formed in the middle of the connecting seat 202. The bottom end of the pressure rod 207 passes through the baffle and the bottom wall of the connecting seat 202. The pressure rod 207 is slidably connected to the connecting seat 202. A limit ring 209 is fixed on the outer wall of the pressure rod 207. A return spring 208 is sleeved on the outer wall of the pressure rod 207. The two ends of the return spring 208 are respectively located between the limit ring 209 and the bottom wall of the connecting seat 202. The two ends of the return spring 208 abut against the limit ring 209 and the bottom wall of the connecting seat 202 respectively. Linear protrusions are also formed on both sides of the pressure rod 207 to prevent axial deflection. The linear protrusions cooperate with the connecting seat 202 to ensure that the pressure rod 207 will not rotate during the up and down movement, thus ensuring the stability of the adjustment.

[0038] like Figure 2 , 3As shown, a movable ring 203 is provided on the side of the annular main pipe 1 near the second drive block 206. The movable ring 203 coincides with the center of the annular main pipe 1 and is connected to the outer wall of the annular main pipe 1 through a limiting seat. The movable ring 203 is slidably connected to the limiting seat. In addition, to ensure the smooth rotation of the movable ring 203, a guide wheel can be added to the contact end face between the limiting seat and the movable ring 203. The second drive block 206 is fixedly connected to the movable ring 203 and can rotate around the center of the annular main pipe 1 under the drive of the movable ring 203.

[0039] like Figure 6 As shown, a drive mechanism 3 is also provided on one side of the movable ring 203, which can push it to rotate and change its rotation direction. The drive mechanism 3 realizes the forward and reverse rotation of the movable ring 203, thereby controlling the movement direction of the second drive block 206 on the top wall of the first drive block 204. In the initial state, when the movable ring 203 is driven to rotate clockwise relative to the annular main pipe 1, the second drive block 206 moves from the lower side to the higher side of the top wall of the first drive block 204, and the pressure rod 207 moves downward, thereby changing the spray angle of the nozzle 201. When the movable ring 203 is driven to rotate counterclockwise relative to the annular main pipe 1, the second drive block 206 moves from the higher side to the lower side of the top wall of the first drive block 204, and the pressure rod 207 begins to reset under the action of the return spring 208, thereby driving the nozzle 201 to rotate and gradually return to the original spray angle.

[0040] The drive mechanism 3 includes a toothed plate 302 fixed to the surface of the movable ring 203 and extending along the direction of the movable ring 203, and a drive gear 301 meshing with the toothed plate 302. A mounting base 304 is provided between the drive gear 301 and the annular main tube 1. The drive shaft of the drive gear 301 is rotatably connected to the mounting base 304. One end of the drive shaft passes through the mounting base 304 and is fixed with a rotating handle. Pins are provided on both sides of the rotating handle. Multiple sets of through holes for the pins to be inserted and fixed are distributed around the center of the rotating handle on the mounting base 304. The rotation of the rotating handle can drive the drive gear 301 to rotate. The drive gear 301 meshes with the toothed plate 302, thereby driving the movable ring 203 to rotate. By rotating the drive gear 301 in both directions, the rotation direction of the toothed plate 302 and the movable ring 203 is changed. When the rotating handle is properly adjusted, the pins on both sides can be inserted into the corresponding through holes to prevent it from rotating randomly, ensuring the stability of the position of the movable ring 203, and thus ensuring the accuracy of the spray angle adjustment of the nozzle 201.

[0041] In addition, a drive motor can be installed at one end of the transmission shaft of the drive gear 301, and the rotation of the transmission shaft can be controlled through the output end of the drive motor, thereby realizing the automated control of the drive gear 301 and further improving the adjustment efficiency and accuracy of the equipment.

[0042] like Figure 1As shown, multiple sets of annular main pipes 1 can be set according to actual processing and production needs. When multiple sets of annular main pipes 1 are set, each annular main pipe 1 is distributed in parallel along the axial direction, and each annular main pipe 1 can be connected to each other through connectors 4. Connectors 4 can use various existing mechanical connection structures, and the spacing between two adjacent sets of annular main pipes 1 can be adjusted appropriately according to actual usage needs.

[0043] Working principle: First, connect the water inlet port of the annular main pipe 1 to the external cooling medium supply pipe, allowing the cooling medium to flow into the internal flow channel of the annular main pipe 1. When the round blank passes through the center of the annular main pipe 1 under the traction device, the cooling medium flows from the annular main pipe 1 into the connecting branch pipe 5, and then sprays out in a spray form through the nozzle 201 to cool the round blank. According to the diameter of the round blank to be processed, when it is necessary to adjust the spray angle of the nozzle 201, the operator can make relevant adjustments in advance. Simply turn the rotating handle to drive the drive gear 301 to rotate. The drive gear 301 drives the toothed plate 302 and the movable ring 203 to start rotating clockwise relative to the annular main pipe 1. At this time, the second drive block 206 starts from the first The lower side of the top wall of the drive block 204 moves to the higher side, and the pressure rod 207 applies pressure to one end of the nozzle 201, causing the nozzle 201 to rotate around the connection fulcrum with the connecting branch pipe 5. This makes the spray direction of all the nozzles 201 on the annular main pipe 1 more concentrated and pointing towards the center line of the blank. The rotating handle can also be rotated in the opposite direction, the drive gear 301 reverses, and the movable ring 203 rotates counterclockwise relative to the annular main pipe 1. The second drive block 206 moves from the higher side of the top wall of the first drive block 204 to the lower side, and the pressure rod 207 is reset under the action of the return spring 208, driving the nozzle 201 to rotate, widening the spray angle, and allowing the spray direction of all the nozzles 201 to spread outward appropriately, thus expanding the spray coverage area.
