It improves the mechanical properties and surface quality of magnesium-aluminum alloys through high-temperature rolling. The core of the equipment consists of a heating system, a hot rolling mill, a transmission system, a roll gap adjustment system, and a cooling and lubrication system. The heating system precisely controls the billet temperature; the rolls are made of high-temperature resistant alloy material and equipped with a hydraulic servo roll gap adjustment device to ensure uniform sheet thickness; the transmission system provides stable torque to drive the rolls to rotate in reverse, completing the sheet rolling; the cooling and lubrication system uses a special medium to reduce roll temperature and friction, preventing scratches on the sheet surface, ultimately producing magnesium-aluminum alloy sheets that meet precision and performance requirements, widely used in aerospace, automotive lightweighting, and other fields.

[0016] 2. This invention uses a position adjustment mechanism to drive the cleaning mechanism to move up and down. Since the temperature of the hot rolling rolls cannot be too high during the hot rolling of magnesium-aluminum alloy, it is necessary to cool the hot rolling rolls.

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.
[0021] For example Figures 1-9 The hot rolling equipment for magnesium-aluminum alloy plates shown includes a base 1 and a power output device 8. A frame 2 is fixedly connected to the top of the base 1. A power mechanism 3 is provided on the outer wall of the frame 2 for outputting power. A position adjustment mechanism 4 is provided on the top of the base 1. A cleaning mechanism 5 is provided on the outer wall of the frame 2 for adjusting the position of the cleaning mechanism 5. Two hot rolling rolls 6 are rotatably connected inside the frame 2. A universal rod 7 is fixedly connected to one end of the hot rolling rolls 6. The two output ends of the power output device 8 are respectively fixedly connected to the ends of the two universal rods 7 away from the frame 2. The base 1, frame 2, hot rolling rolls 6, universal rods 7 and power output device 8 are combined to form a hot rolling mill.
[0022] The power mechanism 3 includes a pressure stabilizing tank 301, which is used to stabilize the air pressure. The pressure stabilizing tank 301 is fixedly connected to one side of the outer wall of the frame 2. An electromagnetic control valve 302 is fixedly connected to the top of the pressure stabilizing tank 301, which controls the opening and closing of the air passage. An air pump 303 is fixedly connected to one side of the outer wall of the frame 2, which provides gas. A connecting pipe 304 is fixedly connected between the electromagnetic control valve 302 and the output end of the air pump 303. An air pipe connector 305 is fixedly connected to the bottom of the pressure stabilizing tank 301. A ventilation hose 306 is fixedly connected to the top interface of the air pipe connector 305. A connecting pipe 1 307 is fixedly connected to the middle of the outer wall of the air pipe connector 305. A connecting pipe 2 308 is fixedly connected to the bottom of the outer wall of the air pipe connector 305. The air pipe connector 305, the ventilation hose 306, the connecting pipe 1 307, and the connecting pipe 2 308 all have the function of ventilation.
[0023] The position adjustment mechanism 4 includes two fixed cylinders 401. A movable plug 402 is slidably connected inside each fixed cylinder 401. A lifting column 403 is fixedly connected to the top of the movable plug 402. After gas enters the fixed cylinder 401, the lifting column 403 can push the movable plug 402 upwards and also push the lifting column 403 upwards. A connecting pipe 404 is fixedly connected to the bottom of each fixed cylinder 401. The connecting pipe 404 serves to allow airflow and provides an installation position. A fixed plug ring 405 is fixedly connected inside the connecting pipe 404. A sliding frame 407 is slidably connected inside the connecting pipe 404. A connecting rod 408 is fixedly connected to the middle of the sliding frame 407. The connecting rod 408 serves a connecting function. A plug head is fixedly connected to the side of the connecting rod 408 away from the sliding frame 407. 409. The sliding frame 407 can maintain the stability of the movement of the plug 409. After the plug 409 is blocked inside the fixed plug ring 405, it can prevent the connecting pipe 404 from being vented. Thus, it can prevent the gas inside the fixed cylinder 401 from being discharged when no gas enters the inside of the fixed cylinder 401. The connecting pipe 404 is equipped with a return spring 406. When no gas enters the connecting pipe 404, the return spring 406 will drive the sliding frame 407 to return to its original position. This will drive the plug 409 to return to its original position through the connecting rod 408, so that the plug 409 can be blocked inside the fixed plug ring 405. The two connecting pipes 404 are fixedly connected to the splicing pipe 417. The splicing pipe 417 is fixedly connected to the control valve 418, which can control the opening and closing of the air passage.
[0024] A fixed base 410 is fixedly connected to the top of the connecting pipe 3 404. The fixed base 410 provides a channel for gas discharge. Multiple air holes 411 are opened on the outer wall of the fixed base 410, which can discharge gas. A fixed column 412 is fixedly connected to the top of the fixed base 410, which provides an installation position. A sliding plate 413 is slidably connected inside the fixed column 412. The sliding plate 413 can move under the push of gas. A connecting column 414 is fixedly connected to the bottom of the sliding plate 413, which has a connecting function. A push spring 415 is provided inside the fixed column 412. The push spring 415 can drive the sliding plate 413 to reset when no gas enters the interior of the fixed column 412. A blocking ring 416 is fixedly connected to the bottom of the connecting column 414, which blocks the inside of the air hole 411. Then, it can prevent gas from escaping. After the blocking ring 416 moves to the position of the vent 411, the gas inside the fixed cylinder 401 can be discharged. The blocking ring 416 is slidably connected to the inside of the fixed seat 410. The top of the two fixed columns 412 is fixedly connected to the splicing pipe 419. The splicing pipe 419 is fixedly connected to the air valve 420. One end of the return spring 406 abuts against one side of the fixed plug ring 405. The other end of the return spring 406 abuts against one side of the sliding frame 407. One end of the push spring 415 abuts against the inside of the fixed column 412. The other end of the push spring 415 abuts against the bottom of the sliding plate 413. The inside of the control valve 418 is fixedly connected to the end of the connecting pipe 308 away from the air pipe connector 305. The inside of the air valve 420 is fixedly connected to the end of the connecting pipe 307 away from the air pipe connector 305.
[0025] The air pump 303 is started, and the air pump 303 introduces gas into the pressure stabilizing tank 301 through the connecting pipe 304, and then into the splicing pipe 417 through the connecting pipe 308. The gas then enters the connecting pipe 404 through the splicing pipe 417, thereby pushing the plug 409 away from the sliding frame 407, overcoming the elastic force of the return spring 406. Once the plug 409 is no longer blocking the fixed plug ring 405, gas enters the connecting pipe 404 and then into the bottom of the fixed cylinder 401, pushing the movable plug 402 upwards. This, in turn, pushes the cleaning mechanism 5 upwards, closing the control valve 41. 8. When the air valve 420 is opened, the gas will enter the interior of the fixed column 412 through the connecting pipe 307 and the splicing pipe 419, thereby pushing the sliding plate 413 downward. This will overcome the elastic force of the push spring 415 and drive the blocking ring 416 to move downward using the connecting column 414. When the air hole 411 is no longer blocked by the blocking ring 416, the gas in the connecting pipe 404 can be discharged, which in turn can discharge the gas in the fixed cylinder 401. Since the size of the air hole 411 is limited, the air inside the fixed cylinder 401 will not be discharged instantly. This allows the gas in the fixed cylinder 401 to be discharged slowly, which in turn drives the movable plug 402 and the lifting column 403 to move downward slowly.
[0026] The cleaning mechanism 5 includes two liquid-filling cylinders 501, which can hold water-based cleaning fluid containing rust inhibitors and degreasers. This cleaning fluid can clean while simultaneously cooling the system. The core cooling is achieved through convection heat transfer and evaporative cooling, reflecting an integrated cooling operation concept in industry. A pusher plate 502 is slidably connected inside the liquid-filling cylinder 501. The pusher plate 502 can move under the pressure of gas, thereby squeezing out the liquid inside the liquid-filling cylinder 501. The internal design of the liquid-filling cylinder 501 is... A push spring 503 is provided, which can drive the push plate 502 to reset after no gas enters the liquid filling cylinder 501. An installation cylinder 505 is fixedly connected to the side of the liquid filling cylinder 501 near the hot rolling roll 6, providing an installation position. An injection pipe 504 is fixedly connected to the top of the liquid filling cylinder 501, facilitating the injection of liquid into the cylinder. A retaining spring 506 is installed inside the installation cylinder 505, which pushes the limit frame 507 to reset. A limiting frame 507 is slidably connected inside the mounting cylinder 505. An inlet head 508 is fixedly connected to the side of the limiting frame 507 away from the mounting cylinder 501. When the inlet head 508 slides into the mounting cylinder 505, it prevents the liquid in the mounting cylinder 505 from draining out. Conversely, when the inlet head 508 moves away from the mounting cylinder 505, it facilitates the drainage of the liquid. A movable rod 509 is fixedly connected to the side of the inlet head 508 away from the limiting frame 507. A scraper 510 is fixedly connected between the two movable rods 509. The scraper 510 can scrape... To remove impurities from the surface of the lower hot rolling roll 6, a fixing block 511 is fixedly connected to the side of the scraper 510 near the hot rolling roll 6. The side of the fixing block 511 near the hot rolling roll 6 is curved, so when the fixing block 511 contacts the hot rolling roll 6, it can exert a force on the scraper 510 in the direction of the mounting cylinder 505, thereby causing the liquid inlet head 508 to move out of the interior of the mounting cylinder 505. Both ends of the scraper 510 near the hot rolling roll 6 are fixedly connected to absorbent cotton 512, which can apply the cleaning liquid to the outer wall of the hot rolling roll 6. In practice, the preferred method is to cover both the upper and lower ends of the scraper 510 near the hot rolling roll 6 along the direction of rotation of the hot rolling roll 6 with absorbent cotton 512, so that when the hot rolling roll 6 rotates, it will come into contact with the absorbent cotton 512, the scraper 510 and the absorbent cotton 512 in sequence.
[0027] The movable rod 509 has a liquid passage groove 513 inside, which serves to allow liquid to pass through. A liquid passage pipe 514 is fixedly connected inside the movable rod 509, also serving to allow liquid to pass through. One end of the liquid passage pipe 514, away from the limiting frame 507, is located inside the upper absorbent cotton 512, and the other end is located inside the lower absorbent cotton 512. A liquid distribution pipe 515 is fixedly connected between the two liquid-filling cylinders 501. A solenoid valve 516 is connected to the frame 2. Slide grooves 519 are provided inside both sides of the frame 2. Limiting sliding blocks 517 are slidably connected inside the slide grooves 519. The limiting sliding blocks 517 provide the installation position and, in cooperation with the slide grooves 519, achieve the function of sliding limit. An installation frame 518 is fixedly connected between the two limiting sliding blocks 517. When the cleaning mechanism 5 slowly moves downwards following the lifting column 403, the fixed block 511 will first contact the outer wall of the hot rolling roll 6, causing the fixed block 511 to be subjected to lateral compressive force. At this time, the fixed block 511... The liquid will then move towards the liquid-filling cylinder 501, thereby driving the movable rod 509, the limit bracket 507, and the liquid inlet head 508 to move into the mounting cylinder 505. At this time, the liquid inlet head 508 moves out of the mounting cylinder 505 on the side away from the liquid-filling cylinder 501. Therefore, the liquid inlet head 508 is not obstructed, and the liquid in the mounting cylinder 505 will enter the interior of the water-absorbing and oil-absorbing cotton 512 through the liquid inlet head 508, the liquid passage groove 513, and the liquid passage pipe 514. When the cleaning mechanism 5 moves downward, the solenoid valve 516 needs to be opened to allow the air to pass through. The liquid enters the liquid-filling cylinder 501 through the liquid-dispensing pipe 515, thereby pushing the liquid-pushing plate 502 to move towards the mounting cylinder 505. This allows the liquid inside the liquid-filling cylinder 501 to be squeezed into the mounting cylinder 505 and the liquid-passing groove 513. When the water-absorbing and oil-absorbing cotton 512 comes into contact with the outer wall of the hot rolling roller 6, the rotation of the hot rolling roller 6 allows the cleaning liquid to be applied to the outer wall of the hot rolling roller 6. And because the scraper 510 is in close contact with the outer wall of the hot rolling roller 6, the impurities on the hot rolling roller 6 are scraped off, thus achieving automatic cleaning.
[0028] The outer walls of the two liquid filling cylinders 501 are fixedly connected to the inside of the mounting frame 518. One end of the push spring 503 abuts against the inside of the liquid filling cylinder 501, and the other end of the push spring 503 abuts against one end of the push plate 502. One end of the clamping spring 506 abuts against the inside of the mounting cylinder 505, and the other end of the clamping spring 506 abuts against the side of the limit frame 507 away from the movable rod 509. The inside of the solenoid valve 516 is fixedly connected to the end of the ventilation hose 306 away from the air pipe connector 305. The end of the scraper 510 away from the mounting cylinder 505 is adjacent to the hot rolling roller 6. In practice, the preferred method is that the scraper 510 is in contact with the hot rolling roller 6.
[0029] As the cleaning mechanism 5 slowly moves downwards following the lifting column 403, the fixing block 511 will first contact the outer wall of the hot rolling roll 6, causing the fixing block 511 to be subjected to lateral extrusion force. At this time, the fixing block 511 will move towards the liquid filling cylinder 501, thereby driving the movable rod 509, the limit frame 507, and the liquid inlet head 508 to move into the interior of the mounting cylinder 505. At this time, the liquid inlet head 508 moves out of the mounting cylinder 505 on the side away from the liquid filling cylinder 501. Therefore, the liquid inlet head 508 is not obstructed, and the liquid in the mounting cylinder 505 will enter the water and oil suction through the liquid inlet head 508, the liquid passage groove 513, and the liquid passage pipe 514. Inside the cotton 512, when the cleaning mechanism 5 moves downward, the solenoid valve 516 needs to be opened, so that gas enters the liquid filling cylinder 501 through the liquid distribution pipe 515, thereby pushing the liquid pusher plate 502 to move towards the mounting cylinder 505, thereby squeezing the liquid inside the liquid filling cylinder 501 into the mounting cylinder 505 and the liquid passage 513. When the water-absorbing and oil-absorbing cotton 512 comes into contact with the outer wall of the hot roller 6, due to the rotation of the hot roller 6, the cleaning liquid can be applied to the outer wall of the hot roller 6, and because the scraper 510 is in close contact with the outer wall of the hot roller 6, the impurities on the hot roller 6 are scraped off, thus achieving automatic cleaning.
[0030] Working principle: When the air pump 303 is started, it introduces gas into the pressure stabilizing tank 301 through the connecting pipe 304, and then into the splicing pipe 417 through the connecting pipe 308. The gas then enters the connecting pipe 404 through the splicing pipe 417, thereby pushing the plug 409 away from the sliding frame 407, overcoming the spring force of the return spring 406. Once the plug 409 is no longer blocking the fixed plug ring 405, gas enters the connecting pipe 404 and reaches the bottom of the fixed cylinder 401, pushing the movable plug 402 upwards. This, in turn, pushes the cleaning mechanism 5 upwards, and the control is then closed. When valve 418 is opened, gas will enter the interior of fixed column 412 through connecting pipe 307 and splicing pipe 419, thereby pushing sliding plate 413 downward. This will overcome the elastic force of push spring 415 and drive blocking ring 416 downward using connecting column 414. When the vent 411 is no longer blocked by blocking ring 416, the gas in connecting pipe 3 404 can be discharged, which in turn can discharge the gas in fixed cylinder 401. Since the size of vent 411 is limited, the air inside fixed cylinder 401 will not be discharged instantly, so the gas in fixed cylinder 401 can be discharged slowly, which will drive movable plug 402 and lifting column 403 to move slowly downward.
[0031] As the cleaning mechanism 5 slowly moves downwards following the lifting column 403, the fixing block 511 will first contact the outer wall of the hot rolling roll 6, causing the fixing block 511 to be subjected to lateral extrusion force. At this time, the fixing block 511 will move towards the liquid filling cylinder 501, thereby driving the movable rod 509, the limit frame 507, and the liquid inlet head 508 to move into the interior of the mounting cylinder 505. At this time, the liquid inlet head 508 moves out of the mounting cylinder 505 on the side away from the liquid filling cylinder 501. Therefore, the liquid inlet head 508 is not obstructed, and the liquid in the mounting cylinder 505 will enter the suction tube through the liquid inlet head 508, the liquid passage groove 513, and the liquid passage pipe 514. Inside the oil-absorbing cotton 512, when the cleaning mechanism 5 moves downward, the solenoid valve 516 needs to be opened, so that gas enters the liquid-filling cylinder 501 through the liquid-distributing pipe 515, thereby pushing the liquid-pushing plate 502 to move towards the mounting cylinder 505, thereby squeezing the liquid inside the liquid-filling cylinder 501 into the mounting cylinder 505 and the liquid-passing groove 513. When the water-absorbing and oil-absorbing cotton 512 comes into contact with the outer wall of the hot roller 6, due to the rotation of the hot roller 6, the cleaning liquid can be applied to the outer wall of the hot roller 6, and because the scraper 510 is in close contact with the outer wall of the hot roller 6, the impurities on the hot roller 6 are scraped off, realizing automatic cleaning.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
