Description

Technical Field

[0001] The invention relates to the technical field of hot rolling, in particular to a continuous casting unit for producing aluminum-titanium alloy profiles and a casting process thereof. Background Art

[0002] Hot rolling is rolling performed above the recrystallization temperature. Simply put, a piece of steel billet is heated and rolled several times, then trimmed and corrected into a steel plate. This is called hot rolling. It can significantly reduce energy consumption and reduce costs. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the processing performance of metals and alloys, that is, crush the coarse grains in the cast state, significantly heal cracks, reduce or eliminate casting defects, transform the cast structure into a deformed structure, and improve the processing performance of the alloy.

[0003] There are several problems with the existing hot rolling treatment of aluminum-titanium alloy profiles: 1. The existing hot rolling treatment of aluminum-titanium alloy profiles adopts a multi-roller step-type method to gradually compress the thickness of the aluminum-titanium alloy profiles to finally achieve the purpose of hot rolling forming, but the multi-roller step-type method occupies a large space and requires multiple motors or driving forces to complete; 2. Uncleaned oxides will adhere to the aluminum-titanium alloy profiles, and these oxides will not only adhere to their surfaces for a second time, but also adhere to the hot rolling rollers, causing damage or scratches to the hot rolling rollers.

The outer sides of the second extension plate are respectively fixedly connected to the first sliding plate and the double-headed rod.

[0014] A casting process for an aluminum-titanium alloy profile production continuous casting machine group includes the following steps: Step 1: Start the servo motor, causing the first hot rolling roll connected to its output end through a coupling to rotate clockwise. At the same time, the conveyor belt connected to the outside of its output end will transmit this rotational force to the rotating shaft. One end of the rotating shaft is connected to the sun gear inside the planetary gearbox. Additionally, the internal gear ring inside the planetary gearbox is connected to the hollow shaft. Therefore, the hollow shaft will rotate in the opposite direction to the rotating shaft. Immediately afterwards, the friction sleeve connected to the other end of the hollow shaft will, under the action of friction, drive the jackshaft to rotate counterclockwise. The outside of the jackshaft is connected to the first gear, and the bottom of the first gear is connected to the rack. Therefore, the bottom connecting strip fixedly connected to the bottom of the rack will move inward along the fixed rail. The outer end face of the rack is connected to the cleaning blade through a patch plate. Therefore, the cleaning blade will move towards the collection mechanism and be pressed against and adapted to the second hot rolling roll inside it to remove impurities or adhered residual oxides on the surface of the second hot rolling roll; Step 2: Pass the heated aluminum-titanium alloy profiles through between the first hot rolling roll and the second hot rolling roll respectively. Immediately afterwards, the first hot rolling roll driven by the servo motor will convey the aluminum-titanium alloy profiles forward and perform rolling casting treatment on them by the two hot rolling rolls. The second hot rolling roll rotates passively and rotates due to the extrusion friction on the top of the aluminum-titanium alloy profiles. Therefore, the second gear fixedly connected to its outside will rotate in the opposite direction to the first hot rolling roll. The bottom of the second gear is in meshing transmission with the third gear. Therefore, the third gear will rotate and move outward along the surface of the threaded rod. Additionally, the outside of the third gear is connected to the bearing through a fixed ring, and the outside of the bearing is connected to the sleeve plate. Therefore, the sleeve plate will move outward together with the third gear and drive the insertion plate connected to its outside to extend outward from the second sliding plate. An outer plate is fixedly connected to the outside of the insertion plate, and the other end of the outer plate is connected to the first inclined plate. As the first inclined plate moves outward, the second inclined plate originally pressed by it will extend outward under the elastic force of the return spring. Additionally, the other end of the second inclined plate is connected to the impurity receiving frame. Therefore, the impurity receiving frame will move outward along the inner cavities of the limited-slip rod and the compensation frame respectively until it moves to the bottom of both ends of the second hot rolling roll to collect the cleaned impurities and oxides; Step 3: By rotating the first hot rolling roll clockwise, the rotating tube connected to the other end thereof will rotate. A hollow sleeve is arranged on the outer side of the rotating tube, and the two are interconnected. In addition, the hollow sleeve is connected to an external hydraulic injection machine. Therefore, the inside of the rotating tube will be filled with new hydraulic oil. Whenever the perforations opened on the surface of the rotating tube rotate to the bottom and communicate with the hole grooves, the hydraulic oil inside the rotating tube will sequentially enter the fixed tube through the perforations and the hole grooves. The other end of the fixed tube is connected to the bent tube. Therefore, the hydraulic oil will be injected into the inside of the bent tube from the bottom end of the bent tube. As the hydraulic oil fills the bent tube, the hydraulic oil will squeeze the sliding plug upward. The space enclosed by the inside of the bent tube and the top of the sliding plug is filled with gas. Therefore, as the sliding plug moves upward, the gas in the upper half of the inner cavity of the bent tube will be compressed and push the piston head downward. Immediately afterwards, the piston head will push the second extension plate downward, causing the second hot rolling roll rotatably connected to the other end of the second extension plate to move downward, so as to realize the slow downward movement of the second hot rolling roll and the slow rolling and forming treatment of the aluminum-titanium alloy profile.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By moving the cleaning blade towards the collecting mechanism and squeezing and matching with the second hot rolling roll inside it, it can clean the impurities on the surface of the second hot rolling roll or the impurities attached to the surface of the aluminum-titanium alloy profile that are not completely removed, and at the same time prevent the remaining oxides or impurities after adhesion from adhering to the surface of the aluminum-titanium alloy profile again.

[0016] 2. By moving the impurity receiving frame outward along the inner cavities of the anti-slip rod and the compensation frame until it reaches the bottom of both ends of the second hot rolling roll, it can collect the cleaned impurities and oxides, prevent them from floating in the air, or prevent them from adhering to the surface of the aluminum-titanium alloy profile again.

[0017] 3. By the piston head pushing the second extension plate downward, the second hot rolling roll rotatably connected to the other end of the second extension plate will move downward and stretch the hydraulic rod, so as to make the second hot rolling roll move downward slowly and perform slow rolling and forming treatment on the aluminum-titanium alloy profile.

Detailed implementation manners

[0033] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 14 , the present invention provides a technical solution: As shown in Figure 1 、 Figure 2 and Figure 3 , it includes a cleaning mechanism 4, which is used for cleaning the oxides on the surface of the hot rolling roll; a collection mechanism 5, which is used for collecting impurities and oxides; a roll adjustment mechanism 6, which is used for adjusting the position of the hot rolling roll; A support frame 2 is installed at both ends of the collecting mechanism 5, the bottom of the support frame 2 is fixedly connected to a bottom plate 1, a No. 1 hot rolling roller 3 is rotatably installed on the inner side of the support frame 2, a cleaning mechanism 4 is fixedly installed on the top of the support frame 2, and a roller adjustment mechanism 6 is fixedly installed on the outer side of the support frame 2.

[0035] The cleaning mechanism 4 includes a servo motor 41, the output end of the servo motor 41 is connected to the first hot rolling roller 3 through a coupling, the bottom of the servo motor 41 is fixedly connected to a frame 42, the frame 42 is fixedly connected to the outside of the support frame 2, the outer side of the output end of the servo motor 41 is transmission-connected with a conveyor belt 43, the top of the inner cavity of the conveyor belt 43 is transmission-connected with a rotating shaft 44, the end of the rotating shaft 44 away from the conveyor belt 43 is connected to a planetary gear box 45, the outer side of the planetary gear box 45 is fixedly connected to a box sleeve 46, the box sleeve 46 is fixedly connected to the top of the support frame 2, the end of the planetary gear box 45 away from the rotating shaft 44 is connected to a hollow shaft 47, the end of the hollow shaft 47 away from the planetary gear box 45 is fixedly connected to a friction sleeve 48, and the end of the friction sleeve 48 away from the hollow shaft 47 is extruded and adapted with a top shaft 49. Start the servo motor 41, so that the No. 1 hot rolling roller 3 connected to its output end through the coupling will rotate clockwise, and the conveyor belt 43 connected to the outer side of the output end will transmit the rotational force to the rotating shaft 44, wherein the other end of the rotating shaft 44 is connected to the sun gear inside the planetary gear box 45, and the inner ring gear inside the planetary gear box 45 is connected to the hollow shaft 47, so the hollow shaft 47 will rotate in the opposite direction to the rotating shaft 44, wherein the planetary gear box 45 converts the forward rotational force of the rotating shaft 44 into the reverse rotational force for the hollow shaft 47, and then the friction sleeve 48 connected to the other end of the hollow shaft 47 will rotate counterclockwise with the top shaft 49 under the action of friction.

[0036] The outer side of the jackshaft 49 is rotatably connected to a shaft seat 40. The shaft seat 40 is fixedly connected to the top of the support frame 2. One end of the jackshaft 49 away from the friction sleeve 48 is fixedly connected to a shaft sleeve 408. One end of the shaft sleeve 408 away from the jackshaft 49 is fixedly connected to a spring 409. One end of the spring 409 away from the shaft sleeve 408 is fixedly connected to a vertical plate 400. Among them, the other end of the jackshaft 49 is connected to the shaft sleeve 408, and the other end of the shaft sleeve 408 is connected to the vertical plate 400 through the spring 409. Therefore, when the jackshaft 49 rotates to a certain angle and the rack 402 moves inward to the limit position, the spring 409 will be rotated and compressed to the maximum extent. At the same time, the frictional force between the friction sleeve 48 and the jackshaft 49 will be less than the rotational compression force of the spring 409 at this moment. Therefore, the friction sleeve 48 will always maintain the frictional extrusion of the jackshaft 49 but will no longer drive the jackshaft 49 to rotate, resulting in the frictional force and the rotational compression force of the spring 409 being in a balanced state. The vertical plate 400 is fixedly connected to the top of the support frame 2. A first gear 401 is fixedly connected to the outer side of the jackshaft 49. A rack 402 is meshed and driven at the bottom of the first gear 401. A bottom connecting strip 403 is fixedly connected to the bottom of the rack 402. The bottom of the bottom connecting strip 403 is slidably fitted with a fixed rail 404. The fixed rail 404 is fixedly connected to the top of the support frame 2. A attaching plate 405 is fixedly connected to the outer end face of the rack 402. A cleaning blade 407 is fixedly connected to the bottom of the attaching plate 405. A through strip 406 is fixedly connected to the inner side of the attaching plate 405. The through strip 406 penetrates through the outer side of the support frame 2 and extends to the other side. Among them, the outer side of the jackshaft 49 is connected to the first gear 401, and the bottom of the first gear 401 is connected to the rack 402. Therefore, the bottom connecting strip 403 fixedly connected to the bottom of the rack 402 will move inward along the fixed rail 404. And the outer end face of the rack 402 is connected to the cleaning blade 407 through the attaching plate 405. Therefore, the cleaning blade 407 will move towards the collecting mechanism 5. Among them, on the side of the cleaning blade 407 close to the collecting mechanism 5, the central thickness of this side is greater than the thickness of both sides. Therefore, the impurities removed will move towards both sides of the cleaning blade 407 and be squeezed and fitted with the second hot rolling roll 51 inside it, so as to play a role in cleaning the impurities on the surface of the second hot rolling roll 51 or the impurities attached to the surface of the aluminum-titanium alloy profile that are not completely removed, and at the same time play a role in preventing the residual oxides or impurities after attachment from adhering to the surface of the aluminum-titanium alloy profile again.

[0037] Such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the collecting mechanism 5 includes a second hot rolling roll 51. By passing the heated aluminum-titanium alloy profile through between the first hot rolling roll 3 and the second hot rolling roll 51 respectively, then the first hot rolling roll 3 driven by the servo motor 41 will convey the aluminum-titanium alloy profile forward and it will be subjected to roll casting treatment by the two hot rolling rolls. The two ends of the second hot rolling roll 51 are respectively rotatably connected to a first sliding plate 52 and a second sliding plate 53. Both the first sliding plate 52 and the second sliding plate 53 are slidably adapted to the two ends of the support frame 2. One end of the second sliding plate 53 away from the second hot rolling roll 51 is fixedly connected to a first extension plate 54. The inner side of the first extension plate 54 is fixedly connected to a double-headed rod 55. The inside of the second sliding plate 53 is fixedly connected to a hydraulic rod 56. The hydraulic rod 56 is fixedly connected to the top of the inner cavity of the support frame 2. The outside of the hydraulic rod 56 is fixedly connected to a buffer spring 57. The outside of the second hot rolling roll 51 is fixedly connected to a second gear 58. A third gear 59 is meshed and driven at the bottom of the second gear 58. A threaded rod 50 is threadedly connected to the central part of the third gear 59. The threaded rod 50 is fixedly connected to the inside of the second sliding plate 53. One end of the threaded rod 50 away from the second sliding plate 53 is fixedly connected to a limit disc 501. The outer end face of the third gear 59 is fixedly connected to a fixing ring 502. The outside of the fixing ring 502 is press-fitted with a bearing 503. The outside of the bearing 503 is press-fitted with a sleeve plate 504.

[0038] A bottom of the second slide plate 53 is fixedly connected with a bottom embedded frame 505. An inside of the bottom embedded frame 505 is fixedly connected with a short shaft 506. An outside of the short shaft 506 is rotatably connected with an adjusting handle 507. An outside of the adjusting handle 507 is fixedly connected with a spring strip 508. One end of the spring strip 508 away from the adjusting handle 507 is fixedly connected to an inside of the bottom embedded frame 505. A side of the sleeve plate 504 away from the third gear 59 is fixedly connected with an inserting plate 509. The inserting plate 509 is inserted into the second slide plate 53 and extends to its outside. An outside of the inserting plate 509 is fixedly connected with an outer plate 500. One end of the outer plate 500 away from the inserting plate 509 is fixedly connected with a first inclined surface plate 5001. A sloped portion of the first inclined surface plate 5001 is press-fitted with a second inclined surface plate 5002. One end of the second inclined surface plate 5002 away from the first inclined surface plate 5001 is fixedly connected with a debris connecting frame 5003. A bottom of the debris connecting frame 5003 is slidably fitted with a compensation frame 5004. Wherein, a thickness of the third gear 59 is less than a thickness of the second gear 58. Therefore, when the third gear 59 moves outward along the threaded rod 50 to a position inside the limit disk 501, the third gear 59 will be disengaged from the second gear 58, causing the debris connecting frame 5003 to always maintain a state of protruding outward. Additionally, when it is necessary to make the third gear 59 re-engage with the second gear 58 and make the debris connecting frame 5003 retract into the compensation frame 5004 again, manually rotate the adjusting handle 507 clockwise, so that its bottom end will squeeze the third gear 59 and make it reverse and re-engage with the second gear 58. Additionally, during the above-mentioned repositioning operation process, the servo motor 41 is in a closed state. When the third gear 59 and the second gear 58 re-engage, rotate the second hot rolling roller 51 in the reverse direction. The outside of the compensation frame 5004 is fixedly connected with the second slide plate 53. An inside of the second slide plate 53 is fixedly connected with a partition plate 5006. One side of the partition plate 5006 away from the second slide plate 53 is fixedly connected with a limiting slide rod 5005. The outside of the limiting slide rod 5005 is inserted into the debris connecting frame 5003. Both ends of the debris connecting frame 5003 are symmetrically connected with end plates 5007. An inside of the end plates 5007 is fixedly connected with a return spring 5008. One end of the return spring 5008 away from the end plates 5007 is fixedly connected with the partition plate 5006.Among them, the second hot rolling roll 51 rotates passively. It rotates due to the extrusion friction on the top of the aluminum-titanium alloy profile. Therefore, the second gear 58 fixedly connected to its outer side will rotate in the opposite direction to the first hot rolling roll 3. The bottom of the second gear 58 meshes and drives with the third gear 59. Therefore, the third gear 59 will rotate and move outward along the surface of the threaded rod 50. In addition, the outer side of the third gear 59 is connected to the bearing 503 through the fixed ring 502, and the outer side of the bearing 503 is connected to the sleeve plate 504. Therefore, the sleeve plate 504 will move outward together with the third gear 59, and drive the insertion plate 509 connected to its outer side to extend outward from the second sliding plate 53. The outer part of the insertion plate 509 is fixedly connected with the outer plate 500, and the other end of the outer plate 500 is connected to the first inclined panel 5001. As the first inclined panel 5001 moves outward, the second inclined panel 5002 originally pressed by it will extend outward under the elastic force of the return spring 5008. The return spring 5008 plays a role in resetting the impurity receiving frame 5003 and the second inclined panel 5002. In addition, the other end of the second inclined panel 5002 is connected to the impurity receiving frame 5003. Therefore, the impurity receiving frame 5003 will move outward along the inner cavities of the limited-slip rod 5005 and the compensation frame 5004 respectively until it reaches the bottom of both ends of the second hot rolling roll 51, so as to collect and process the impurities and oxides cleaned by the cleaning blade 407, avoid floating in the air, or re-adhering to the surface of the aluminum-titanium alloy profile.

[0039] Such as Figure 12 , Figure 13 and Figure 14As shown in the figure, the roll adjusting mechanism 6 includes a rotating tube 61, which is fixedly connected to the end face of the first hot rolling roll 3. A hollow sleeve 62 is arranged outside the rotating tube 61, and the hollow sleeve 62 is fixedly connected to the outside of the support frame 2. A perforation 63 is formed on the surface of the rotating tube 61. One end of the rotating tube 61 away from the hollow sleeve 62 is rotatably connected to a fixed tube 64. A hole groove 65 is formed at the bottom of the inner cavity of the fixed tube 64. One end of the fixed tube 64 away from the rotating tube 61 is fixedly connected to a bent tube 66. A first limiting block 67 and a second limiting block 68 are respectively fixedly connected inside the bent tube 66. A sliding plug 69 is slidably fitted inside the bent tube 66, and the sliding plug 69 is arranged between the first limiting block 67 and the second limiting block 68. A tube seat 60 is fixedly connected to the outside of the bent tube 66, and the tube seat 60 is fixedly connected to the outside of the support frame 2. One end of the bent tube 66 away from the fixed tube 64 is inserted with a piston head 601. The bottom of the piston head 601 is press-fitted with a second extension plate 602. The outside of the second extension plate 602 is respectively fixedly connected to the first sliding plate 52 and the double-headed rod 55. By the clockwise rotation of the first hot rolling roll 3, the rotating tube 61 connected to the other end thereof will rotate. A hollow sleeve 62 is arranged outside the rotating tube 61, and the two are interconnected. In addition, the hollow sleeve 62 is connected to an external hydraulic injection machine. Therefore, the inside of the rotating tube 61 will be filled with new hydraulic oil. Whenever the perforation 63 formed on the surface of the rotating tube 61 rotates to the bottom and communicates with the hole groove 65, the hydraulic oil inside the rotating tube 61 will sequentially enter the fixed tube 64 through the perforation 63 and the hole groove 65. The other end of the fixed tube 64 is connected to the bent tube 66. Therefore, the hydraulic oil will be injected into the inside of the bent tube 66 from the bottom end of the bent tube 66. As the hydraulic oil fills the bent tube 66, the hydraulic oil will squeeze the sliding plug 69 upward. The space enclosed by the inside of the bent tube 66 and the top of the sliding plug 69 is filled with gas. Therefore, as the sliding plug 69 moves upward, the gas in the upper half of the inner cavity of the bent tube 66 will be compressed and push the piston head 601 downward. Immediately, the piston head 601 will push the second extension plate 602 downward, causing the second hot rolling roll 51 rotatably connected to the other end of the second extension plate 602 to move downward and stretch the hydraulic rod 56, thereby playing a role in slowly moving the second hot rolling roll 51 downward and slowly roll-forming the aluminum-titanium alloy profile. In addition, the above reset can be achieved by simply pumping out the injected hydraulic oil.
