Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy casting and rolling, in particular to a casting and rolling equipment for aluminum alloy casting and rolling. Background Art

[0002] The aluminum alloy casting and rolling process is a process in which aluminum melt is introduced into the gap between two rotating rollers with cooling water flowing inside, and the rollers are directly used as crystallizers to roll while solidifying to produce aluminum strip billets that can be directly rolled.

[0003] At present, aluminum alloy casting and rolling equipment generally includes a casting nozzle mechanism and upper and lower rollers, wherein one end of the casting nozzle mechanism extends between the upper and lower rollers, and the side seal of the casting nozzle mechanism and the upper and lower rollers together form a casting and rolling area. In the prior art, molten aluminum liquid is poured from one end of the casting nozzle mechanism. When the aluminum liquid enters the casting and rolling area, it solidifies rapidly between the roller gaps of the upper and lower rollers and is rolled by the rollers at the same time to form an aluminum strip blank.

[0004] However, after the aluminum alloy billet is formed by rolling by the upper and lower rollers, the left and right sides of the aluminum alloy billet will abut against the side sealing plates of the casting nozzle mechanism, and as the aluminum alloy billet continues to move forward, friction will also occur between the aluminum alloy billet and the side sealing plates. Under the action of friction, cracks will form on the sides of the aluminum alloy billet, thereby affecting the quality of the aluminum alloy billet.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1 - Figure 8 A casting and rolling equipment for aluminum alloy casting and rolling comprises an upper rolling roll 100, a lower rolling roll 200 and a casting nozzle mechanism 300. The upper rolling roll 100 and the lower rolling roll 200 are symmetrically distributed in the upper and lower parts. The casting nozzle mechanism 300 extends between the upper rolling roll 100 and the lower rolling roll 200. The casting nozzle mechanism 300 comprises two side sealing plates 301. An upper sealing plate 302 and a lower sealing plate 303 are arranged between the two side sealing plates 301. The two side sealing plates 301 and the upper sealing plate 302 and the lower sealing plate 303 together form a casting nozzle channel. Support plates 304 are arranged on the left and right sides of the inside of the casting nozzle channel. The two support plates 304 are fixedly connected to the two side sealing plates 301 respectively. The length of the side sealing plate 301 is greater than the length of the upper sealing plate 302 and the lower sealing plate 303, and the side sealing plate 301 is aligned with one end of the upper sealing plate 302 and the lower sealing plate 303.

[0041] The upper roller 100 and the lower roller 200 are in the shape of a stepped shaft which is wide in the middle and narrow at both ends. The middle sections of the upper roller 100 and the lower roller 200 are respectively embedded in the upper and lower surface areas between the two side sealing plates 301, and the width of the middle section of the upper roller 100 and the lower roller 200 is adapted to the spacing between the two side sealing plates 301. The two side sealing plates 301, the upper roller 100 and the lower roller 200 together form a casting and rolling interval.

[0042] Furthermore, the facing surfaces of the two side sealing plates 301 are provided with movable slots 305, and anti-sticking graphite blocks 400 are provided in the movable slots 305. The anti-sticking graphite blocks 400 are shorter than the length of the movable slots 305. Figure 7 Specifically, one end of the movable notch 305 extends to the rear side of the support plate 304. The opposite back sides of the two side sealing plates 301 are provided with drive assemblies 500 distributed along the length direction of the side sealing plates 301, and the output ends of the two drive assemblies 500 are respectively connected to the two anti-sticking graphite blocks 400. The drive assembly 500 in this embodiment adopts a slide cylinder, the cylinder body of the slide cylinder is fixedly connected to the outer surface of the side sealing plate 301, and the movable end of the slide cylinder is connected to the anti-sticking graphite block 400, which is used to control the anti-sticking graphite block 400 to slide along the length direction of the side sealing plate 301.

[0043] In some embodiments of the present application, a mounting plate 401 is further provided in the movable notch 305, and the two mounting plates 401 are respectively located on opposite sides of the two anti-sticking graphite blocks 400, and a slider 402 distributed vertically is provided on the mounting plate 401, and the anti-sticking graphite block 400 is slidably matched with the slider 402. That is, the anti-sticking graphite block 400 can slide vertically relative to the mounting plate 401.

[0044] In addition, a telescopic connecting rod 501 is fixedly provided at the output end of the driving assembly 500. Figure 7 As shown, the back of the side sealing plate 301 is provided with a strip opening 306 which is communicated with the movable notch 305 and for the telescopic connecting rod 501 to pass through, and one end of the telescopic connecting rod 501 passes through the strip opening 306 and is fixedly connected to the assembly plate 401. The outer sleeve of the telescopic connecting rod 501 is provided with a pulling spring 502, and the two ends of the pulling spring 502 are respectively abutted against the two ends of the telescopic connecting rod 501, and in a natural state, the pulling spring 502 is in a stretched state. The telescopic connecting rod 501 is formed by two round tubes being sleeved with each other, so the length of the telescopic connecting rod 501 can be freely extended and retracted within a certain range. The driving assembly 500 can indirectly drive the anti-sticking graphite block 400 to move forward and backward through the telescopic connecting rod 501 and the assembly plate 401, and the anti-sticking graphite block 400 can also slip in the longitudinal direction.

[0045] The inner surface of the movable notch 305 is provided with a driving groove 307 on both the front and rear sides. The driving groove 307 is a closed groove body shape composed of a first horizontal groove body 3071, a first inclined groove body 3072, a second horizontal groove body 3073 and a second inclined groove body 3074 connected end to end in sequence, and the driving groove 307 is in a parallelogram shape. Two guide posts 403 are provided on one side of the anti-sticking graphite block 400 facing the assembly plate 401. The assembly plate 401 is provided with guide grooves 404 on both the front and rear sides for the guide posts 403 to pass through and distributed vertically. The two guide posts 403 pass through the corresponding guide grooves 404 and are embedded in the two driving grooves 307. Therefore, when the driving assembly 500 drives the assembly plate 401 to slide back and forth, the guide posts 403 can also reciprocate along the driving groove 307. The length of the driving groove 307 does not exceed one third of the length of the movable notch 305 . When the guide post 403 is located at any position inside the driving groove 307 , one end of the anti-sticking graphite block 400 is always located at the rear side of the support plate 304 .

[0046] It should be noted that when the guide column 403 is located inside the first horizontal slot 3071 and the first inclined slot 3072, the driving component 500 controls the translation direction and speed of the assembly plate 401 to be consistent with the translation direction and speed of the aluminum alloy billet; when the guide column 403 is located in the second horizontal slot 3073 and the second inclined slot 3074, the driving component 500 controls the translation direction of the assembly plate 401 to be opposite to the moving direction of the aluminum alloy billet, and at this time the translation speed of the assembly plate 401 is faster than the translation speed of the aluminum alloy billet, which serves to shorten the reset time of the anti-sticking graphite block 400.

[0047] The depth of the second inclined groove body 3074 is greater than the depth of the first horizontal groove body 3071, the first inclined groove body 3072 and the second horizontal groove body 3073, and the inner surfaces of the first and second ends of the second inclined groove body 3074 are connected to the first horizontal groove body 3071 and the second horizontal groove body 3073 through smooth inclined surfaces; in the natural state, due to the pulling force of the pulling spring 502, the end of the guide column 403 abuts against the inner surface of the driving groove 307, and when the guide column 403 abuts against the inner surfaces of the first horizontal groove body 3071, the first inclined groove body 3072 and the second horizontal groove body 3073, the outer surface of the anti-sticking graphite block 400 is flush with the surface of the side sealing plate 301; when the guide column 403 abuts against the inner surface of the second inclined groove body 3074, the outer surface of the anti-sticking graphite block 400 is retracted into the inner side of the movable groove 305.

[0048] It should be noted that the anti-sticking graphite block 400 is an L-shaped plate structure. Figure 4 , 5As shown, a wider section of the anti-sticking graphite block 400 extends into the rear side of the support plate 304, and when the guide column 403 is located at any position in the driving groove 307, the narrowest distance between the upper roller 100 and the lower roller 200 is always located at the wider section facing the anti-sticking graphite block 400, that is, the edge of the aluminum alloy billet after being rolled by the upper roller 100 and the lower roller 200 can abut against the anti-sticking graphite block 400.

[0049] It is worth mentioning that the front end width of the anti-sticking graphite block 400 is shorter than half of the front end width inside the movable slot 305, the spacing between the first horizontal slot body 3071 and the second horizontal slot body 3073 is consistent with the front end width of the anti-sticking graphite block 400, and when the guide column 403 is located inside the second horizontal slot body 3073, there is a gap between the bottom end of the anti-sticking graphite block 400 and the inner bottom surface of the movable slot 305.

[0050] In this embodiment, when the driving assembly 500 controls the assembly plate 401 to reciprocate back and forth, the guide post 403 can cyclically move in the driving slot 307 along the first horizontal slot 3071, the first inclined slot 3072, the second horizontal slot 3073 and the second inclined slot 3074. In order to ensure that the guide post 403 can smoothly transition from the first inclined slot 3072 to the second horizontal slot 3073, and to ensure that the guide post 403 can smoothly transition from the second inclined slot 3074 to the first horizontal slot 3071, the first inclined slot 3072, the second horizontal slot 3073 and the second inclined slot 3074 71, the inner surface of the movable slot 305 and the junction of the first inclined slot body 3072 and the second horizontal slot body 3073, as well as the junction of the second inclined slot body 3074 and the first horizontal slot body 3071 are provided with installation notches, in which an anti-overflow block 308 is rotatably provided, and a torsion spring (not shown in the figure) is mounted on the rotating shaft of the anti-overflow block 308. Under the action of the torsion spring, when the anti-overflow block 308 is not subjected to external force, the outer surface of the anti-overflow block 308 is always flush with the inner surface of the driving slot 307, as shown in FIG. Figure 8 As shown, when the guide post 403 transitions from the first inclined slot 3072 to the second horizontal slot 3073, and transitions from the second inclined slot 3074 to the first horizontal slot 3071, the guide post 403 can overcome the torsion force of the torsion spring and knock open the anti-overflow block 308. When the guide post 403 is located at the junction of the first inclined slot 3072 and the second horizontal slot 3073, and at the junction of the second inclined slot 3074 and the first horizontal slot 3071, the anti-overflow block 308 can be reset under the action of the torsion spring, thereby ensuring that the guide post 403 can always circulate and move in the driving slot 307.

[0051] In addition, it should be noted that when the guide column 403 moves inside the first horizontal groove body 3071, the left and right ends of the aluminum alloy billet rolled by the upper roller 100 and the lower roller 200 can abut against the anti-sticking graphite block 400. Since the movement direction and speed of the anti-sticking graphite block 400 at this time are consistent with the direction and speed of the aluminum alloy billet, the aluminum alloy billet and the anti-sticking graphite block 400 will not generate relative friction, thereby avoiding cracks on the edges of the aluminum alloy billet.

[0052] When the guide post 403 enters the first inclined slot 3072 from the first horizontal slot 3071, the anti-sticking graphite block 400 still has the same speed as the aluminum alloy billet in the horizontal direction, but in the vertical direction, the anti-sticking graphite block 400 will move downward and thus separate from the aluminum alloy billet. When the guide post 403 moves inside the second horizontal groove body 3073, the front section of the anti-sticking graphite block 400 is no longer in contact with the aluminum alloy billet, and the rear section of the anti-sticking graphite block 400 is still in contact with the aluminum alloy billet. However, since the aluminum alloy billet has not yet been fully cooled and solidified, even if there is a relative displacement between it and the anti-sticking graphite block 400, the friction between the two is small, so no obvious cracks will appear; when the guide post 403 moves to the inside of the second inclined groove body 3074, the anti-sticking graphite block 400 moves upward in the vertical direction, and at this time the outer surface of the anti-sticking graphite block 400 is retracted into the movable slot 305, so as to prevent the front section of the anti-sticking graphite block 400 from rubbing against the edge of the aluminum alloy billet when the anti-sticking graphite block 400 moves upward.

[0053] Furthermore, since the junction between the second inclined trough body 3074 and the first horizontal trough body 3071 is transitioned through an inclined surface, when the guide column 403 enters the first horizontal trough body 3071 from the second inclined trough body 3074, under the action of the inclined surface, the anti-sticking graphite block 400 can pop outward and be flush with the outer surface of the side sealing plate 301, so that the anti-sticking graphite block 400 can re-contact the edge of the aluminum alloy billet.

[0054] Example 2: Please refer to Fig. 9 - Fig.14 The embodiment of the present application also proposes a casting and rolling equipment for aluminum alloy casting and rolling. The difference between this embodiment and the first embodiment is that: a seat plate 600 is also provided between the two side sealing plates 301, and a flip plate 601 is provided on the top surface of the seat plate 600. The flip plate 601 is rotatably matched with the seat plate 600 on the side close to the casting nozzle passage, and the width of the flip plate 601 is equivalent to the spacing between the two side sealing plates 301; when the flip plate 601 is in contact with the seat plate 600, the upper surface of the flip plate 601 is in a horizontal posture. A rotating shaft 602 is rotatably provided on the top surface of the seat plate 600 and on the upper surface on the side close to the casting nozzle passage, and an assembly groove 603 is provided at the end of the flip plate 601. The rotating shaft 602 is located in the assembly groove 603 and is fixedly connected to the flip plate 601.

[0055] Furthermore, an embedded groove 604 is provided on the top surface of the seat plate 600 and below the rotating shaft 602. A main shaft 605 is rotatably provided in the embedded groove 604. A driving gear 607 is fixedly sleeved on the upper part of the main shaft 605. A driven gear 606 is fixedly sleeved on the outer part of the rotating shaft 602. The driving gear 607 and the driven gear 606 are meshed. A rack 608 is also provided on one side of the inner part of the embedded groove 604, which is connected in a vertical sliding manner. The rack 608 is meshed with the driving gear 607. The left and right ends of the rack 608 are A driving rod 609 is provided, and the front and rear side walls of the seat plate 600 are provided with a through hole 610 connected to the embedded groove 604, and one end of the driving rod 609 passes through the through hole 610 and extends into the movable groove 305; when the guide column 403 is located inside the first horizontal groove body 3071, the anti-sticking graphite block 400 is not in contact with the driving rod 609; when the guide column 403 is located inside the second horizontal groove body 3073, the anti-sticking graphite block 400 is in contact with the driving rod 609, and the flip plate 601 is in an inclined posture.

[0056] In the natural state, that is, when the driving rod 609 is not subjected to external force, due to the effect of gravity, the flip plate 601 can fit the seat plate 600 and remain horizontal. At this time, the rack 608 is located at a relatively upper position, such as Fig.14 When the anti-stick graphite block 400 presses the drive rod 609 downward, the rack 608 moves downward, thereby driving the driving gear 607 and the driven gear 606 to rotate, so that the flip plate 601 flips upward to an inclined posture.

[0057] It should be noted that when the guide column 403 moves in the first inclined slot 3072, the anti-sticking graphite block 400 moves downward and separates from the aluminum alloy billet, and when the anti-sticking graphite block 400 moves downward, the flip plate 601 will flip and tilt upward, thereby pushing the aluminum alloy billet to move upward, that is, increasing the separation speed of the anti-sticking graphite block 400 and the aluminum alloy billet in the vertical direction. Compared with separation at a low speed, the separation speed of the anti-sticking graphite block 400 and the aluminum alloy billet in this embodiment is faster. Since there is a certain viscosity between the anti-sticking graphite block 400 and the aluminum alloy billet, if the separation is slow, the adhesive force may cause damage to the edge of the aluminum alloy billet; however, in the case of rapid separation, due to the effect of inertia, it can help to make the edge of the aluminum alloy billet smoother and reduce the probability of edge cracks as much as possible.

[0058] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
