Description

Technical Field

[0001] This utility model relates to the field of vibration technology for continuous casting machines, and in particular to a vibration device for metallurgical continuous casting machines. Background Technology

[0002] The function of the vibration device is to facilitate the penetration of protective slag through the reciprocating motion of the vibration device and the crystallizer during the billet formation process, forming a lubricating film between the copper tube and the billet, reducing the frictional resistance during billet pulling, and preventing the billet from sticking to the inner wall of the copper tube of the crystallizer during the solidification process, thus preventing sticking, tearing and leakage accidents, and ensuring the smooth demolding of the billet.

[0003] A search revealed that Chinese Patent Publication No. CN210937042U provides a vibration device for a continuous casting machine, comprising a fixed frame, a lower connecting rod, an upper connecting rod, a vibration frame, and a transmission mechanism. One end of the upper connecting rod is hinged to the upper end of the fixed frame, and the other end is hinged to one side of the vibration frame. One end of the lower connecting rod is hinged to the lower end of the fixed frame, and the other end is hinged to the transmission mechanism. The middle section of the lower connecting rod is hinged to the lower end of the vibration frame. This device has a simple structure, small vibration sway, high vibration frequency, and more reasonable force distribution on each mechanism, extending equipment life, ensuring billet quality, and reducing maintenance costs.

[0004] However, in the existing technology, the vibration device of the continuous casting machine is usually equipped with a vibrating arm. The crystallizer is placed on the vibrating arm and then hydraulic vibration is used for vibration. After long-term use, the metal fatigue of the vibrating arm is high, which makes the vibrating arm easy to be damaged and is not conducive to subsequent normal use. A solution is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibration device for a metallurgical continuous casting machine, which aims to improve the problem that the vibration device of a continuous casting machine is usually equipped with a vibration arm. By placing the crystallizer on the vibration arm and then using hydraulic vibration to perform vibration work, the vibration arm has high metal fatigue after long-term use, which makes the vibration arm easy to be damaged and is not conducive to subsequent normal use.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a mounting base and a vibration table. A mounting bracket is fixedly connected to one side of the vibration table. A second sliding cylinder is fixedly connected to the lower end of the mounting bracket. Sliding grooves are formed around the upper end of the mounting base. A slider is slidably engaged with the inner surface of each of the four sliding grooves. A buffer rod is rotatably connected to the upper end of each of the four sliders. The upper ends of the four buffer rods are rotatably connected to the four corners of the lower end of the vibration table. A first buffer spring is fixedly connected to one side of each of the four sliders. Sliding rods are provided on both sides of the upper end of the mounting base. A first buffer spring is fixedly connected to both ends of each of the two sliding rods. The mounting bracket has two fixing blocks, one side of which is fixedly connected to the other end of two buffer springs. The two sides of the outer surfaces of the two slide rods are slidably connected to the lower part of the four sliders. The middle of the outer surfaces of the two slide rods is fixedly connected to a second fixing block. One side of the two second fixing blocks is fixedly connected to one side of the other two buffer springs. The lower ends of the four first fixing blocks are fixedly connected to the four corners of the upper end of the mounting base. The lower ends of the two second fixing blocks are fixedly connected to the two sides of the upper end of the mounting base. Reinforcing ribs are fixedly connected to both sides of the outer surface of the mounting bracket.

[0007] As a further description of the above technical solution: In this utility model, when the device vibrates the crystallizer, its vibration table moves up and down with the amplitude of the vibration. When the vibration table moves downward due to vibration, the four buffer rods at the lower end of the vibration table will rotate and push the slider at the other end to slide to one side. When the slider slides, it will compress the first buffer spring on the side. The compressed first buffer spring can buffer and cancel the vibration force. After buffering is completed, the first buffer spring will push the slider back and prepare to cancel the next vibration. In this way, the force on the vibration rod can be minimized when the device vibrates the crystallizer, thereby maximizing the relief of metal fatigue of the device and extending the service life of the device.

[0008] Preferably, a fixed base is fixedly connected to the upper end of the mounting base, and a motor is fixedly connected to the upper end of the fixed base.

[0009] As a further description of the above technical solution: the fixed base can be used to fix the motor, which can provide power for the vibration of the device.

[0010] Preferably, the output end of the motor is fixedly connected to a connector, and a connecting rod is rotatably connected to one side inside the connector.

[0011] As a further description of the above technical solution: the connector is a pear-shaped part, which can make up-down reciprocating motion when rotated.

[0012] Preferably, a support rod is rotatably connected to the other side of the connector, and a connecting block is rotatably connected to the upper end of the connecting rod.

[0013] As a further description of the above technical solution: the support rod can support and fix the other side of the connector, and the connecting block can be used to fix the first slide cylinder.

[0014] Preferably, a first sliding cylinder is fixedly connected to the upper end of the connecting block, and the outer surface of the first sliding cylinder is slidably connected to the inner surface of the second sliding cylinder.

[0015] As a further description of the above technical solution: the first slide can slide inside the second slide.

[0016] Preferably, the first slide cylinder has a groove inside, and a buffer rod is slidably connected inside the groove.

[0017] As a further description of the above technical solution: the buffer rod can slide up and down in the slot.

[0018] Preferably, buffer pads are fixedly connected to both ends of the buffer rod.

[0019] As a further description of the above technical solution: the buffer pad can replace the buffer rod in contact with the inside of the first slide when it contacts the buffer rod. The buffer pad is made of relatively soft rubber, which can effectively prevent the buffer rod from being damaged after long-term use.

[0020] Preferably, a second buffer spring is fixedly connected to the upper end of one of the buffer pads.

[0021] As a further description of the above technical solution: the second buffer spring can be compressed when the buffer rod moves, and push the buffer rod back after compression, so that the first slide cylinder is more stable when sliding up and down.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. In this utility model, when the device vibrates the crystallizer, its vibration table moves up and down with the amplitude of the vibration. When the vibration table moves downward due to vibration, the four buffer rods at the lower end of the vibration table will rotate and push the slider at the other end to slide to one side. When the slider slides, it will compress the first buffer spring on the side. The compressed first buffer spring can buffer and cancel the vibration force. After buffering is completed, the first buffer spring will push the slider back and prepare to cancel the next vibration. In this way, the force on the vibration rod can be minimized when the device vibrates the crystallizer, thereby maximizing the relief of metal fatigue of the device and extending the service life of the device.

[0024] 2. In this utility model, when the crystallizer needs to be vibrated, it is only necessary to turn on the motor. The rotation of the motor drives the connecting part to rotate, and the rotating connecting part will drive the connecting rod to move up and down reciprocatingly. When the connecting rod moves, the connecting block and the first slide cylinder connected to it will also move up and down reciprocatingly, causing the first slide cylinder to slide upward into the second slide cylinder. The second slide cylinder will be lifted up by the contact buffer rod, so that it can also move up and down reciprocatingly. This method can make the vibration frequency more stable and the vibration direction more accurate when the device is vibrating. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, one embodiment of this utility model includes a mounting base 1 and a vibration table 19. A mounting bracket 17 is fixedly connected to one side of the vibration table 19, and a second slide cylinder 16 is fixedly connected to the lower end of the mounting bracket 17. Slide grooves 6 are formed around the upper end of the mounting base 1, and sliders 5 are slidably engaged on the inner surfaces of the four slide grooves 6. Buffer rods 9 are rotatably connected to the upper ends of the four sliders 5, and the upper ends of the four buffer rods 9 are rotatably connected to the four corners of the lower end of the vibration table 19. A buffer spring 4 is fixedly connected to one side of each of the four sliders 5. Slide rods 3 are provided on both sides of the upper end of the mounting base 1, and both ends of the two slide rods 3 are fixedly connected to... There is a first fixing block 2, one side of two first fixing blocks 2 are respectively fixedly connected to the other end of two first buffer springs 4, the two sides of the outer surface of two slide rods 3 are respectively slidably connected to the bottom of four sliders 5, the middle of the outer surface of two slide rods 3 are fixedly connected to the second fixing block 7, one side of two second fixing blocks 7 are respectively fixedly connected to one side of another two first buffer springs 4, the lower ends of four first fixing blocks 2 are respectively fixedly connected to the four corners of the upper end of the mounting base 1, the lower ends of two second fixing blocks 7 are respectively fixedly connected to the two sides of the upper end of the mounting base 1, and the two sides of the outer surface of the mounting bracket 17 are fixedly connected to the reinforcing ribs 18.

[0034] In this embodiment, when the device vibrates the crystallizer, its vibration table 19 moves up and down with the amplitude of the vibration. When the vibration table 19 is vibrated and moves downward, the four buffer rods 9 at the lower end of the vibration table 19 will rotate and push the slider 5 at the other end to slide to one side. When the slider 5 slides, it will compress the first buffer spring 4 on the side. The compressed first buffer spring 4 can buffer and cancel the vibration force. After buffering is completed, the first buffer spring 4 will push the slider 5 back and prepare to cancel the next vibration. In this way, the force on the vibration rod can be minimized when the device vibrates the crystallizer, which can alleviate the metal fatigue of the device to the greatest extent and extend the service life of the device.

[0035] Example 2, as Figure 1 - Figure 3As shown, a fixed base 26 is fixedly connected to the upper end of the mounting base 1, a motor 10 is fixedly connected to the upper end of the fixed base 26, a connector 12 is fixedly connected to the output end of the motor 10, a connecting rod 13 is rotatably connected to one side of the connector 12, a support rod 11 is rotatably connected to the other side of the connector 12, a connecting block 14 is rotatably connected to the upper end of the connecting rod 13, a first slide cylinder 15 is fixedly connected to the upper end of the connecting block 14, the outer surface of the first slide cylinder 15 is slidably connected to the inner surface of the second slide cylinder 16, a groove 24 is opened inside the first slide cylinder 15, a buffer rod 22 is slidably connected inside the groove 24, buffer pads 20 are fixedly connected to both ends of the buffer rod 22, and a second buffer spring 21 is fixedly connected to the upper end of one of the buffer pads 20.

[0036] In this embodiment, when the crystallizer needs to be vibrated, it is only necessary to turn on the motor 10. The rotation of the motor 10 drives the connecting member 12 to rotate, and the rotating connecting member 12 drives the connecting rod 13 to move up and down reciprocally. When the connecting rod 13 moves, the connecting block 14 and the first slide cylinder 15 connected to it will also move up and down reciprocally, causing the first slide cylinder 15 to slide upward into the second slide cylinder 16. The second slide cylinder 16 will be lifted by the contact buffer rod 22, so that it can also move up and down reciprocally. This method makes the vibration frequency more stable and the vibration direction more accurate when the device is vibrating.

[0037] Working principle: When the crystallizer needs to be vibrated, simply turn on the motor 10. The rotation of the motor 10 drives the connecting part 12 to rotate, which in turn drives the connecting rod 13 to move up and down. When the connecting rod 13 moves, the connecting block 14 and the first slide cylinder 15 connected to it will also move up and down, causing the first slide cylinder 15 to slide upward into the second slide cylinder 16. The second slide cylinder 16 will be lifted by the contact buffer rod 22, allowing it to also move up and down. At the same time, the vibration table 19 will move up and down with the amplitude of the vibration. When the vibration table 19 is vibrated and moves downward, the four buffer rods 9 at the lower end of the vibration table 19 will rotate and push the slider 5 at the other end to slide to one side. When the slider 5 slides, it will compress the first buffer spring 4 on the side. The compressed first buffer spring 4 can buffer and cancel the vibration force. After buffering, the first buffer spring 4 will push the slider 5 back and prepare to cancel the next vibration.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
