Description

Technical Field

[0001] This application relates to the field of rolling mill production equipment, and in particular to a spray quenching machine. Background Technology

[0002] Support rolls are important components in rolling mills. They provide support during rolling and prevent the work rolls from bending and deforming, which would affect the output and quality of plates and strips.

[0003] The support roll essentially supports the work roll. By having the work roll contact the workpiece, the diameter of the work roll can be reduced and its rigidity increased. However, due to the stress conditions on the support roll, it is prone to roll breakage, chipping off of the roll edges, and spalling, which greatly affects the normal operation of the rolling mill. Utility Model Content

[0004] In order to reduce the likelihood of damage to the support rollers during use, this application provides a spray quenching machine.

[0005] The spray quenching machine provided in this application adopts the following technical solution:

[0006] A spray quenching machine includes a frame, with two parallel rotating rollers at the bottom of the frame. The two rotating rollers are connected to a rotating motor for driving the two rotating rollers to rotate. Multiple nozzles for spraying water onto the rotating rollers are provided on the upper side of the two rotating rollers. Two opposing baffles are provided on the lower side of the nozzles for shielding the ends of the rolls placed on the rotating rollers.

[0007] By adopting the above technical solution, when the roll needs to be quenched by spraying, the roll is placed between two rotating rolls, and then the rotating motor is started to drive the rotating roll and the roll to rotate. Then, two baffles are used to block the two ends of the roll, and then water is sprayed onto the roll through the nozzle. This makes it difficult for the ends of the roll to come into direct contact with water for quenching, thereby reducing the phenomenon that the hardness of the roll ends increases due to quenching, which may lead to damage to the ends of the roll during subsequent use and affect the use of the roll.

[0008] Optionally, each of the baffles is connected to a moving component, which is used to move the baffle.

[0009] By adopting the above technical solution, when the required quenching roll size changes, the baffle is moved by the moving component, so that the baffle can block the ends of rolls of different sizes, reducing the phenomenon that the baffle cannot block the ends of the rolls when the roll size changes.

[0010] Optionally, the moving component includes a transverse lead screw fixedly connected to one side of the baffle, the transverse lead screw being threadedly connected to a moving block, and the moving block being connected to an adjacent frame.

[0011] By adopting the above technical solution, when it is necessary to move the baffle, the transverse lead screw is rotated, and the transverse lead screw drives the baffle to move, thereby realizing the process of moving the baffle.

[0012] Optionally, the movable block is slidably connected to the adjacent frame in the vertical direction, and the movable block is penetrated and threadedly connected to a vertically arranged longitudinal sliding screw.

[0013] By adopting the above technical solution, when it is necessary to move the baffle, the longitudinal lead screw is rotated, and the longitudinal lead screw drives the moving block to move during the rotation, and the moving block drives the baffle to move during the movement.

[0014] Optionally, each of the nozzles is connected to a hose, and multiple hoses are connected to the same water tank. The multiple nozzles are connected to the same drive assembly, which is used to move the multiple nozzles.

[0015] By adopting the above technical solution, when water needs to be sprayed onto the rolls, the drive assembly is activated to move the nozzle. The movement of the nozzle ensures that the water sprayed from the nozzle can be evenly sprayed onto the upper side of the rolls, reducing the occurrence of insufficient quenching of the rolls due to uneven water spraying onto the upper side of the rolls.

[0016] Optionally, the drive assembly includes a drive motor, which drives a reciprocating lead screw. The reciprocating lead screw is threaded with multiple drive blocks, which are configured one-to-one with multiple nozzles, and each drive block is connected to the corresponding nozzle.

[0017] By adopting the above technical solution, when it is necessary to move the nozzle, the drive motor is turned on, the drive motor drives the reciprocating screw to rotate, the reciprocating screw drives multiple drive blocks to move during the rotation, and the multiple drive blocks drive the connected nozzle to move during the movement, thereby realizing the process of driving multiple nozzles to move through the drive assembly.

[0018] Optionally, a top material assembly is provided on the lower side of the middle position of the two rotating rollers, the top material assembly being used to drive the roller between the two rotating rollers to move.

[0019] By adopting the above technical solution, after the roll quenching is completed, the roll is moved by the top material assembly, thereby reducing the process of workers moving the rolls onto the rotating rolls.

[0020] Optionally, the top material assembly includes a top material cylinder vertically arranged below the middle position of the two rotating rollers. The top material cylinder is vertically arranged and a top material block is fixedly connected to its upper end. The upper surface of the top material block is inclined.

[0021] By adopting the above technical solution, when it is necessary to move the roll, the top material cylinder is activated to drive the top material block to move. During the movement of the top material block, the roll rotates, thereby realizing the process of moving the roll through the top material assembly.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By using baffles to block the ends of the rolls, the hardness of the roll ends can be reduced during the quenching process, thus minimizing the impact on subsequent use.

[0024] 2. By setting up a movable component, the phenomenon that the baffle is difficult to move according to different roll sizes and that blocks the ends of the rolls is reduced due to changes in the size of the rolls;

[0025] 3. By setting up a drive component, multiple nozzles are moved during the spray quenching process, so that the nozzles can spray water evenly onto the rolls, and the rolls can be quenched evenly. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0031] This application discloses a spray quenching machine, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a frame 1, which comprises two vertically arranged and parallel uprights 11. The upper ends of the two uprights 11 are connected to the same horizontal plate 12. The horizontal plate 12 is horizontally positioned, and a rotating shaft 13 is fixedly connected through and to one side of the horizontal plate 12. The rotating shaft 13 is horizontally positioned, and each end of the rotating shaft 13 is fixedly connected to the adjacent upright 11. A pad is provided on the bottom side of the horizontal plate 12 away from the rotatable connection point with the upright 11 to fix the horizontal position of the horizontal plate 12. Two horizontally arranged rotating rollers 2 are provided on the lower side of the middle position of the two uprights 11, and the end of each rotating roller 2 is rotatably connected to the side wall of the adjacent upright 11.

[0032] Both rollers 2 have connecting gears 21 fixedly connected to their ends facing the same vertical plate 11, and a median wheel 22 is provided between the two connecting gears 21, with the two connecting gears 21 meshing with each other through the median wheel 22. A rotating motor 23 is fixedly connected to one end of one of the rollers 2, passing through the connecting gear 21.

[0033] One of the vertical plates 11 has a water storage tank 3 on one side, and a water pump 33 is connected to one side of the water storage tank 3. Multiple hoses 31 are connected to one side of the water pump 33, and the water pressure guided by the water pump 33 to the hoses 31 is set to 0.4 kPa. Each hose 31 passes through the horizontal plate 12 and is fixedly connected to the horizontal plate 12. Each hose 31 has a nozzle 32 connected to the end away from the water storage tank 3. The multiple nozzles 32 are located on the upper side of the middle position of the two rotating rollers 2, and the multiple nozzles 32 are evenly arranged along the length of the rotating rollers 2.

[0034] Two opposing baffles 4 are provided between the rotating roller 2 and the nozzle 32. Each baffle 4 is C-shaped, and the C-shaped opening of each baffle 4 is downward and faces the middle position of the two rotating rollers 2. The two baffles 4 can block the two ends of the rollers placed on the rotating roller 2.

[0035] When the heated roll needs to be water-quenched, the horizontal plate 12 is rotated to hoist the roll between the two rotating rolls 2, and then the horizontal plate 12 is rotated to a position perpendicular to the vertical plate 11. The end of the roll is then shielded by the baffle 4. The rotating motor 23 is then turned on, driving the connected rotating roll 2 to rotate. During rotation, the rotating roll 2 drives the other rotating roll 2 to rotate via the connecting gear 21 and the intermediate wheel 22. The two rotating rolls 2 drive the roll to rotate, and during this rotation, the roll is water-quenched through the nozzle 32, making it difficult for the roll end to come into contact with water. This allows the roll end to retain a certain degree of ductility after quenching, increasing the roll's service life.

[0036] Each baffle 4 is connected to a moving component 5, which is used to move the baffle 4.

[0037] By setting the moving component 5, when the size of the roll changes, the moving component 5 can drive the baffle 4 to move, blocking the ends of rolls of different sizes, thereby making the device applicable to rolls of more sizes.

[0038] The moving assembly 5 includes a moving screw fixedly connected to the side of each baffle 4 away from the other baffle 4, and each transverse moving screw 51 is horizontally arranged. Each transverse moving screw 51 is externally threaded with a moving block 52, and each moving block 52 is slidably connected to the adjacent vertical plate 11 in the vertical direction.

[0039] Each moving block 52 is penetrated and threaded with a longitudinal sliding screw 53, which is vertically arranged and its end is rotatably connected to the adjacent vertical plate 11.

[0040] In actual use, when it is necessary to move the baffle 4, the transverse lead screw 51 is rotated by a screw, and the transverse lead screw 51 moves the baffle 4 during the movement. By rotating the longitudinal lead screw 53, the longitudinal lead screw 53 moves the moving block 52 during the rotation, and the moving block 52 moves the baffle 4 during the movement, so that the baffle 4 can block the ends of rolls of different sizes by moving.

[0041] Multiple nozzles 32 are connected to a drive assembly 6, which is used to drive the multiple nozzles 32 to swing simultaneously.

[0042] By setting the drive component 6, the drive component 6 can drive multiple nozzles 32 to swing, so that the multiple nozzles 32 can spray water on the roll, so that the part of the roll exposed outside the baffle 4 can fully contact the water for quenching.

[0043] The drive assembly 6 includes a drive motor 61 fixedly connected to the horizontal plate 12. The drive motor 61 is vertically arranged, and its output shaft passes through the horizontal plate 12 and is rotatably connected to it. A drive bevel gear 62 is fixedly connected to the lower end of the output shaft of the drive motor 61. A driven bevel gear 63 meshes with one side of the drive bevel gear 62. A reciprocating screw 64 is fixedly connected to the driven bevel gear 63 and is horizontally arranged. Multiple drive blocks 65 are threaded onto the reciprocating screw 64. Each drive block 65 slides against the adjacent horizontal plate 12, and the reciprocating screw 64 can simultaneously drive multiple drive blocks 65 to reciprocate. The multiple drive blocks 65 are arranged one-to-one with multiple nozzles 32, and each drive block 65 is fixedly connected to the corresponding nozzle 32.

[0044] When the roll is placed on the upper side between the two rotating rolls 2, the drive motor 61 is turned on while the rotating roll 2 drives the roll to rotate. The drive motor 61 drives the drive bevel gear 62 to rotate. During the rotation of the drive bevel gear 62, the driven bevel gear 63 is driven to rotate. During the rotation of the driven bevel gear 63, the reciprocating screw 64 is driven to rotate. During the rotation of the reciprocating screw 64, multiple drive blocks 65 are driven to move back and forth. During the movement of each drive block 65, the connected nozzle 32 is driven to swing, so that the water in the water tank 3 can be evenly sprayed onto the lower roll.

[0045] A top material assembly 7 is provided on the lower side of the middle position of the two rotating rollers 2. The top material assembly 7 is used to drive the upper rollers of the two rotating rollers 2 to move to one side of the frame 1.

[0046] By setting up the top material assembly 7, the process of workers moving the rollers on the upper side of the rotating roller 2 is reduced.

[0047] The top material assembly 7 includes a top material cylinder 71 located below the middle position of the two rotating rollers 2. The top material cylinder 71 is vertically arranged with its piston rod pointing upward. A top material block 72 is fixedly connected to the upper end of the piston rod of the top material cylinder 71. The upper surface of the top material block 72 is gradually inclined downward from one side of the rotating roller 2 toward the other side of the rotating roller 2.

[0048] When it is necessary to move the rotating roller 2 to one side of the frame 1, the top material cylinder 71 is activated. The top material cylinder 71 drives the top material block 72 to move upward. After the top material block 72 moves upward, it drives the rotating roller 2 to move. During the upward movement of the top material block 72, it drives the rotating roller 2 to move, so that the rotating roller 2 can move to one side of the frame 1.

[0049] The implementation principle of a spray quenching machine according to an embodiment of this application is as follows: When it is necessary to spray quench the roll, the roll is placed between two rotating rolls 2, and then the rotating motor 23 is turned on to drive the rotating rolls 2 and the roll to rotate. Then, the transverse lead screw 51 and the longitudinal lead screw 53 are rotated to drive the baffles 4 to move, so that the two baffles 4 can block the two ends of the roll.

[0050] Then, multiple nozzles 32 are turned on and the drive motor 61 is turned on to make the multiple nozzles 32 swing, so that water can be evenly sprayed onto the outside of the roll. After quenching is completed, the top material cylinder 71 is turned on to move the roll to one side of the frame 1, thereby realizing the full spray quenching operation of the roll.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
