Description

Technical Field

[0001] This utility model relates to the field of vibration crystallization technology, and in particular to a vibration table for a billet continuous casting machine crystallizer. Background Technology

[0002] The crystallizer vibration table is one of the key components in a continuous casting machine. Its main function is to improve the lubrication between the billet and the crystallizer interface through vibration, thereby preventing the billet shell from sticking to the crystallizer, improving the surface quality of the billet, and reducing the risk of sticking and leakage.

[0003] A search revealed Chinese patent publication number CN218361965U, which discloses a crystallizer vibration table for a billet continuous casting machine. This patent uses a motor to drive a rotating shaft, and an impact component slides inside the mounting housing. When the impact component moves upward, it strikes the first limiting ring on the limiting sleeve, thereby preventing adhesion to the inner wall of the crystallizer. However, this device has certain problems: the amplitude of the crystallizer vibration directly affects the quality and internal structure of the billet. If the amplitude cannot be adjusted, it can lead to poor lubrication or cracks. Utility Model Content

[0004] The purpose of this utility model is to provide a vibrating table for a billet continuous casting machine crystallizer in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A vibrating table for a billet continuous casting machine includes a table body with symmetrical fixed frames on both sides of the table body. The fixed frames are fixedly connected to the bottom wall of the table body. A transmission mechanism is provided inside the fixed frames. A movable column is provided above the transmission mechanism. The movable column is inverted T-shaped. A fixed plate is fixedly connected to the upper end of the movable column. A limit frame is fixedly installed on the top of the fixed plate. The transmission mechanism drives the limit frame to move up and down through the movable column.

[0007] An adjustment mechanism is provided at the upper end of the fixed frame. The adjustment mechanism changes the amplitude of the limiting frame by adjusting the highest point of the movable column during its movement. The adjustment mechanism includes a fixed cylinder, which is fixedly connected to the top of the fixed frame. A connecting frame is slidably connected to the inner wall of the fixed cylinder. A limiting plate is fixedly connected to the top of the connecting frame. The inner wall of the connecting frame is slidably connected to the movable column. Multiple equally spaced threaded holes are opened on one side of the fixed cylinder, and bolts are threadedly connected to the threaded holes. A limiting hole is opened on the side of the connecting frame near the bolts, and the limiting hole is threadedly connected to the bolt.

[0008] Preferably, an auxiliary spring is fixedly connected inside the movable column, a connecting column is slidably connected to the lower end of the movable column, the connecting column is fixedly connected to the auxiliary spring, and a connecting plate is fixedly connected to the bottom of the connecting column.

[0009] Preferably, the transmission mechanism includes a rotating shaft, which is rotatably mounted at both ends of a fixed frame. A cam assembly is fixedly mounted on the rotating shaft, and a movable rod is rotatably sleeved on the side of the cam assembly away from the rotating shaft.

[0012] Preferably, the lower end of the limiting frame is fixedly connected to the top of the reset spring.

[0013] The beneficial effects are as follows: rotating the bolt disengages it from the threaded hole, then adjusting the distance between the limiting plate and the fixed cylinder causes the connecting frame to slide against the inner wall of the fixed cylinder, so that the limiting hole on the connecting frame corresponds to the appropriate threaded hole. Then, the bolt is screwed into the corresponding threaded hole, so that when the movable column rises to a certain position, it abuts against the limiting plate, thereby adjusting the vibration amplitude of the limiting frame through the movable column.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-4 As shown, a crystallizer vibration table for a billet continuous casting machine includes a table body 101. Symmetrical fixed frames 102 are provided on both sides inside the table body 101. The fixed frames 102 are fixedly connected to the bottom wall inside the table body 101. A transmission mechanism is provided inside the fixed frames 102. A movable column 401 is provided above the transmission mechanism. The movable column 401 is inverted T-shaped. A fixed plate 402 is fixedly connected to the upper end of the movable column 401. A limit frame 7 is fixedly installed on the top of the fixed plate 402. The transmission mechanism drives the limit frame 7 to move up and down through the movable column 401.

[0025] An adjustment mechanism is provided at the upper end of the fixed frame 102. The adjustment mechanism changes the amplitude of the limiting frame 7 by adjusting the highest point of the movable column 401 during movement. The adjustment mechanism includes a fixed cylinder 301, which is fixedly connected to the top of the fixed frame 102. A connecting frame 302 is slidably connected to the inner wall of the fixed cylinder 301. A limiting plate 303 is fixedly connected to the top of the connecting frame 302. The inner wall of the connecting frame 302 is slidably connected to the movable column 401. Multiple equally spaced threaded holes 304 are opened on one side of the fixed cylinder 301. Bolts 305 are threadedly connected to the threaded holes 304. The connecting frame 302... A limiting hole is provided on the side near the bolt 305. The limiting hole is threadedly connected to the bolt 305. The bolt 305 is rotated to disengage from the threaded hole 304. Then, the distance between the limiting plate 303 and the fixed cylinder 301 is adjusted so that the connecting frame 302 slides against the inner wall of the fixed cylinder 301, so that the limiting hole on the connecting frame 302 corresponds to the appropriate threaded hole 304. Then, the bolt 305 is screwed into the corresponding threaded hole 304, so that when the movable column 401 rises to a certain position, it abuts against the limiting plate 303, thereby adjusting the vibration amplitude of the limiting frame 7 through the movable column 401.

[0026] An auxiliary spring is fixedly connected inside the movable column 401. A connecting column 403 is slidably connected to the lower end of the movable column 401. The connecting column 403 is fixedly connected to the auxiliary spring. A connecting plate 404 is fixedly connected to the bottom of the connecting column 403. The connecting plate 404 pushes the connecting column 403 to drive the movable column 401 to move upward. When the lower end of the movable column 401 abuts against the limiting plate 303, the connecting column 403 and the movable column 401 slide, causing the auxiliary spring to compress and deform.

[0027] The transmission mechanism includes a rotating shaft 501, which is rotatably mounted at both ends of the fixed frame 102. A cam assembly 502 is fixedly mounted on the rotating shaft 501. A movable rod 503 is rotatably sleeved on the side of the cam assembly 502 away from the rotating shaft 501. The upper end of the movable rod 503 is rotatably connected to the lower end of the connecting plate 404. The rotating shaft 501 drives the cam assembly 502 to rotate, so that the cam assembly 502 drives the movable rod 503 to move. The upper end of the movable rod 503 drives the connecting plate 404 to move up and down.

[0028] Symmetrical mounting seats 201 are provided between the two fixed frames 102. The mounting seats 201 are fixed to the top of the platform 101. The upper end of the mounting seat 201 is fixedly connected to the mounting shell 202. The bottom wall of the mounting shell 202 is fixedly connected to the return spring 203. When the limit frame 7 vibrates up and down, it causes the return spring 203 to deform.

[0029] The front end of the platform 101 is fixedly equipped with two symmetrical motors 601. The output shaft of the motor 601 is fixedly connected to the front rotating shaft 501 on the same side. A transmission rod 602 is fixedly connected between the front and rear symmetrical rotating shafts 501. The motor 601 drives the front and rear symmetrical rotating shafts 501 on the same side to move synchronously through the transmission rod 602.

[0030] The lower end of the limit frame 7 is fixedly connected to the top of the reset spring 203.

[0031] Working principle: During use, the crystallizer is installed on the limiting frame 7. When it is necessary to change the amplitude of the limiting frame 7, the bolt 305 is rotated to disengage from the threaded hole 304. Then, the distance between the limiting plate 303 and the fixed cylinder 301 is adjusted so that the connecting frame 302 slides against the inner wall of the fixed cylinder 301, so that the limiting hole on the connecting frame 302 corresponds to the appropriate threaded hole 304. Then, the bolt 305 is screwed into the corresponding threaded hole 304, so that when the movable column 401 rises to a certain position, it abuts against the limiting plate 303. Thus, the vibration amplitude of the limiting frame 7 is adjusted through the movable column 401. The motor 601 drives the symmetrical rotating shafts 501 on the same side to move synchronously through the transmission rod 602. The rotating shafts 501 drive the cam group 502 to rotate, which in turn drives the movable rod 503 to move. The upper end of the movable rod 503 drives the connecting plate 404 to move up and down. The connecting plate 404 pushes the connecting column 403 to drive the movable column 401 to move upward. When the lower end of the movable column 401 abuts against the limiting plate 303, the connecting column 403 and the movable column 401 slide, causing the auxiliary spring to compress and deform. This causes the return spring 203 to deform when the limiting frame 7 vibrates up and down.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
