Description

Technical Field

[0001] The invention belongs to the technical field of new energy, and in particular relates to a molten aluminum casting device for producing copper-aluminum composite strips. Background Art

[0002] In the manufacturing process of the pole of new energy batteries, it is necessary to first make a copper-aluminum composite strip by casting and rolling, and then obtain the finished product by stamping. The casting and rolling process means: first, the semi-molten aluminum liquid is cast onto the copper strip by the casting process, and then the aluminum and copper are pressed into shape by the rolling process.

[0003] At present, during the casting process of aluminum liquid, the outflow speed of aluminum liquid is usually constant, while the conveying speed of copper strip will be affected by various equipment such as upstream and downstream of the production line, and it is easy to have speed fluctuations, which will undoubtedly affect the casting speed. If the casting speed is too fast, the aluminum liquid may not be able to fully combine with the copper strip, forming an unstable composite layer; if the casting speed is too slow, the aluminum liquid may be unevenly distributed on the surface of the copper strip, resulting in defects such as uneven thickness, pores, and inclusions in the composite strip.

[0004] Therefore, we propose an aluminum liquid casting equipment for producing copper-aluminum composite strips to solve the above problems. Summary of the invention

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] like Figure 1-Figure 11 As shown, an aluminum liquid casting device for copper-aluminum composite strip production includes a base 1, a conveyor 2 for conveying a copper strip 21 is installed on the upper end of the base 1, and is used to continuously convey the pre-treated copper strip 21 forward, and a heat preservation furnace 4 is also fixedly connected to the base 1 to contain semi-molten aluminum liquid. In order to avoid oxidation, when the device is used, an isolation cover can be added to isolate the aluminum liquid, the copper strip 21, etc. from the external environment.

[0044] The lower end of the holding furnace 4 is connected with an output channel 41, the lower end of the output channel 41 is fixedly connected with a diverter trough 5, the diverter trough 5 has a first diverter pipe 51 and a second diverter pipe 52, the upper end of the base 1 is fixedly connected with a recovery furnace 6, the first diverter pipe 51 is used to cast the copper strip 21, and the second diverter pipe 52 is used to output the excess aluminum liquid to the recovery furnace 6. In the present invention, on the basis of the normal setting of the casting pipeline, a spare aluminum liquid recovery pipeline is also provided, when the demand for aluminum liquid casting is reduced, the excess aluminum liquid can be discharged from the recovery pipeline, so as to prevent the aluminum liquid from accumulating in the diverter trough 5 and solidifying, thereby causing blockage.

[0045] An adjusting mechanism is provided between the first shunt pipe 51 and the second shunt pipe 52 to control the shunt speed of the first shunt pipe 51. A control unit 3 is provided on one side of the conveyor 2. The control unit 3 is electrically connected to the conveyor 2 and the adjusting mechanism, respectively, so that the adjusting mechanism can adjust the shunt speed of the first shunt pipe 51 according to the conveying speed of the conveyor 2. Specifically, an angular velocity sensor is provided on the conveyor 2 to obtain the output speed information of the conveyor 2, and the adjusting mechanism is controlled by the control unit 3. When the control unit 3 obtains the conveying speed information of the conveyor 2, the adjusting mechanism can be adjusted accordingly according to the conveying speed of the conveyor 2, so that the size of the first shunt pipe 51 and the second shunt pipe 52 can be changed, so that the aluminum liquid can be output outward at a uniform speed to avoid the aluminum liquid solidifying in the shunt tank 5.

[0046] The present invention can adjust the amount of cast aluminum liquid according to the conveying speed of the copper belt 21, so that the aluminum liquid can be evenly attached to the copper belt 21 to form a uniform composite layer. At the same time, by providing an additional output pipe, the excess aluminum liquid can be discharged into the recovery furnace 6 through the output pipe to avoid the aluminum liquid solidifying in the diverter trough 5 and causing the diverter trough 5 to be blocked.

[0047] In order to adjust the flow rates of the first diversion pipe 51 and the second diversion pipe 52, a transition groove 54 is provided in the diversion groove 5, and a storage chamber 53 is provided in the diversion groove 5. The transition groove 54 is used to connect the output channel 41 and the first diversion pipe 51 and the second diversion pipe 52. That is to say, the upper end of the transition groove 54 is connected to the lower end of the storage chamber 53, and the upper ends of the first diversion pipe 51 and the second diversion pipe 52 are respectively connected to the lower end of the transition groove 54.

[0048] The regulating mechanism includes a diverter block 7 and a driving assembly 8. The driving assembly 8 is used to drive the diverter block 7 to move. Both ends of the diverter block 7 are fixedly connected with a sliding shaft 71. A horizontally arranged sliding groove opening 543 is opened on the side wall of the transition groove 54. The sliding shaft 71 is slidably arranged in the sliding groove opening 543. The first flow channel 541 and the second flow channel 542 are formed between the two sides of the diverter block 7 and the side walls of the transition groove 54 respectively. The first flow channel 541 is connected to the first diverter pipe 51, and the second flow channel 542 is connected to the second diverter pipe 52. Therefore, when the diverter block 7 moves left and right, the width of the first flow channel 541 and the second flow channel 542 will change, thereby realizing the adjustment of the flow of the first diverter pipe 51 and the second diverter pipe 52, such as Figure 3 shown.

[0049] like Figure 4 , Figure 5 , Figure 6 As shown, a baffle 74 is fixedly connected between the diverter block 7 and the sliding shaft 71. The baffle 74 is slidably and sealedly connected to the inner wall of the transition groove 54. The width of the baffle 74 is not less than twice the length of the slide groove opening 543, so that when the sliding shaft 71 moves, the baffle 74 can always cover the slide groove opening 543, so that when the diverter block 7 moves left and right, the interior of the transition groove 54 can always remain in a closed state, so as to keep the aluminum liquid warm and prevent the aluminum liquid from leaking.

[0050] The driving assembly 8 is electrically connected to the control unit 3. When the conveying speed of the conveyor 2 increases, the driving assembly 8 moves the diverter block 7 toward the second flow channel 542 to increase the flow rate of the first diverter pipe 51. When the conveying speed of the conveyor 2 decreases, the driving assembly 8 moves the diverter block 7 toward the first flow channel 541 to reduce the flow rate of the first diverter pipe 51.

[0051] Specifically, the drive assembly 8 includes an electric cylinder 81, which is fixedly mounted on the outer wall of the transition groove 54. The output end of the electric cylinder 81 is horizontally arranged and consistent with the moving direction of the diverter block 7. The output end of the electric cylinder 81 is fixedly connected to a connecting frame 82. A connecting rod 83 is provided on the side wall of the connecting frame 82. The connecting rod 83 is connected to the sliding shaft 71. When the output end of the electric cylinder 81 is extended, the diverter block 7 is driven to move to the left. When the output end of the electric cylinder 81 is retracted, the diverter block 7 is driven to move to the right. The extension and extension amount of the electric cylinder 81 are controlled by the control unit 3. For example, when the angular velocity sensor detects that the conveying speed of the conveyor 2 slows down, the control unit 3 controls the output end of the electric cylinder 81 to retract, and the amount of retraction is proportional to the change in the angular velocity sensor. Therefore, when the moving speed of the copper belt 21 slows down, the output amount of the aluminum liquid can be reduced synchronously, so that the aluminum liquid can be evenly attached to the copper belt 21.

[0052] like Fig. 9 As shown, in order to prevent aluminum liquid from accumulating on the upper end of the diverter block 7, the diverter block 7 is a horizontally arranged semi-cylinder, the diverter block 7 has a straight surface 73 and an outer arc surface 72, the baffle 74 is a circular plate, and the diverter block 7 is coaxially connected with the baffle 74. A rotating sleeve 831 is fixedly connected to the connecting rod 83, and a damping connection is formed between the rotating sleeve 831 and the sliding shaft 71, so that the diverter block 7 keeps the outer arc surface 72 on the top and the straight surface 73 on the bottom. When the aluminum liquid falls on the outer arc surface 72, it will slide down along the arc-shaped side wall to avoid accumulation.

[0053] like Figure 4 As shown, in order to improve the airtightness between the diverter block 7 and the transition groove 54, the first sealing block 56 and the second sealing block 57 are fixedly connected at the upper notch of the transition groove 54, respectively. The side wall of the first sealing block 56 is provided with a first inner arc surface 561, and the side wall of the second sealing block 57 is provided with a second inner arc surface 571. The first inner arc surface 561 and the second inner arc surface 571 have the same diameter as the diverter block 7, and the centers of the first inner arc surface 561 and the second inner arc surface 571 are located on the moving trajectory of the center of the diverter block, so that the first inner arc surface 561 and the second inner arc surface 571 can both fit on the outer arc surface 72, so that when the diverter block 7 moves to the outermost position, the diverter block 7 can fit tightly with the first sealing block 56 or the second sealing block 57. Specifically, when the copper strip 21 moves at the fastest speed, the control unit 3 controls the electric cylinder 81 to extend, so that the diverter block 7 and the second sealing block 57 fit closely together, so that the upper end of the second flow channel 542 is completely closed, and the first flow channel 541 is opened to the maximum, so that the casting amount of the aluminum liquid is correspondingly increased. When the copper strip 21 stops moving, the control unit 3 retracts the electric cylinder 81, so that the diverter block 7 and the first sealing block 56 fit closely together, so that the upper end of the first flow channel 541 is completely closed, and the aluminum liquid stops casting the copper strip 21.

[0054] Meanwhile, in this embodiment, the diameter of the diverter block 7 is the same as the diameter of the baffle plate 74 , so that the side wall of the baffle plate 74 can also fit together with the first sealing block 56 and the second sealing block 57 .

[0055] In order to prevent the formation of a dead angle between the outer arc surface 72 and the first sealing block 56 and the second sealing block 57, which causes the aluminum liquid to gather at some positions and cause the aluminum liquid to be discharged poorly, as shown in FIG. Figure 6 , Figure 7 As shown, the sliding shaft 71 is coaxially connected with the baffle 74, and a gear 84 is fixedly connected to the outside of the sliding shaft 71. A rack 85 parallel to the slot opening 543 is provided on the outer wall of the transition groove 54, and a section of teeth is provided on both sides of the rack 85. When the sliding shaft 71 moves to the edge of the slot opening 543, the gear 84 meshes with the teeth to drive the sliding shaft 71 to rotate, and drives the straight surface 73 to rotate to a state inclined toward the middle. When the diverter block 7 moves to the right and fits tightly with the first sealing block 56, the gear 84 will act on the teeth on the right side, so that when the diverter block 7 moves forward, it will also rotate around the sliding shaft 71, so that the straight surface 73 rotates to the side close to the second flow channel 542, and accelerates the outflow speed of the aluminum liquid. When the diverter block 7 moves to the left, the gear 84 will act on the teeth on the other side, so that the straight surface 73 rotates to the side close to the first flow channel 541. The aluminum liquid is quickly discharged downward along the inclined straight surface 73 to avoid accumulation. It should be noted that when the diverter block 7 moves to the middle position, the gear 84 will interact with the teeth again to restore the diverter block 7 to the initial state, and the diverter block 7 maintains the state of the outer arc surface 72 on the top and the straight surface 73 on the bottom by relying on the damping connection between the rotating sleeve 831 and the sliding shaft 71. It should be noted that the straight surface 73 is in a horizontal state when the diverter block 7 is in the initial state, so that the outer arc surface 72 is symmetrical about the axis of the sliding shaft 71, thereby improving the guiding effect on the aluminum liquid.

[0056] In addition, the sliding shaft 71 is coaxially connected to the baffle 74 and the diverter block 7, and the diameter of the baffle 74 is equal to the diameter of the diverter block 7. It should be noted that the length of the slide groove mouth 543 is smaller than the radius of the baffle 74, so that when the sliding shaft 71 moves to the extreme position of the slide groove mouth 543, the baffle 74 can still seal the slide groove mouth 543.

[0057] In order to further prevent a small amount of aluminum liquid from dripping down along the diverter block 7 and causing solidification and agglomeration, Figure 8 As shown, a sealing strip 55 is fixedly connected to the bottom of the transition groove 54, and the sealing strip 55 is arranged between the first diversion pipe 51 and the second diversion pipe 52. A third inner arc surface 551 and a fourth inner arc surface 552 are respectively provided on both sides of the sealing strip 55. The third inner arc surface 551 is concentric with the first inner arc surface 561 and has the same radius, and the fourth inner arc surface 552 is concentric with the second inner arc surface 571 and has the same radius.

[0058] When the sliding shaft 71 moves to the left extreme position of the slide groove mouth 543, the diverter block 7 rotates so that the outer arc surface 72 is simultaneously attached to the first inner arc surface 561 and the third inner arc surface 551, so that the straight surface 73 is inclined toward the second diverter pipe 52. When the sliding shaft 71 moves to the right extreme position of the slide groove mouth 543, the diverter block 7 rotates in the opposite direction so that the outer arc surface 72 is simultaneously attached to the second inner arc surface 571 and the fourth inner arc surface 552, so that the straight surface 73 is inclined toward the first diverter pipe 51.

[0059] Through the cooperation of the first sealing block 56, the diverter block 7 and the sealing strip 55, the upper end of the first diverter pipe 51 can be completely blocked, and through the cooperation of the second sealing block 57, the diverter block 7 and the sealing strip 55, the upper end of the second diverter pipe 52 can be completely blocked.

[0060] In addition, when the diverter block 7 is fitted with the first sealing block 56 and rotated into place, the upper end of the straight surface 73 is fitted with the edge of the first inner arc surface 561, and the lower end of the straight surface 73 is fitted with the edge of the third inner arc surface 551, thereby reducing the dead angle. Similarly, when the diverter block 7 is fitted with the second sealing block 57 and rotated into place, the upper end of the straight surface 73 is fitted with the edge of the second inner arc surface 571, and the lower end of the straight surface 73 is fitted with the edge of the fourth inner arc surface 552.

[0061] In order to prevent the baffle 74 from interfering with the sealing strip 55 during movement, the front and rear ends of the sealing strip 55 are fixedly connected to the front and rear side walls of the transition groove 54 respectively, and the upper side walls of the front and rear ends of the sealing strip 55 are provided with a clearance groove 553 matching the baffle 74.

[0062] Finally, it should be noted that the recovery furnace 6 is connected to the holding furnace 4 through the recovery pipe 61. The holding furnace 4 and the recovery furnace 6 form a circulation channel, specifically: holding furnace 4-output channel 41-diverter trough 5-second diverter pipe 52-recovery furnace 6-recovery pipe 61-holding furnace 4. Thus, the unused aluminum liquid can be recycled into the holding furnace 4 and reused.

[0063] The working principle is as follows: in normal use, the copper belt 21 is continuously conveyed forward by the conveyor 2, and the aluminum liquid falls through the holding furnace 4, the output channel 41, the diverter trough 5, and the first diverter pipe 51, and adheres to the surface of the copper belt 21, so as to realize the casting of the copper belt 21. When the conveying speed of the copper belt 21 is reduced, in order to avoid excessive discharge of aluminum liquid and also to prevent the aluminum liquid from being solidified in the diverter trough 5 due to slow discharge speed, the control unit 3 is used to control the electric cylinder 81, so that the electric cylinder 81 shrinks back a certain length, the diverter block 7 moves to the right, the upper opening of the first flow channel 541 becomes narrower, and the discharge amount of the first diverter pipe 51 is reduced. When the conveying speed of the copper belt 21 increases, in order to match the corresponding casting amount, the electric cylinder 81 will extend forward a certain length, the diverter block 7 moves to the left, the upper opening of the first flow channel 541 becomes wider, and the discharge amount of the first diverter pipe 51 is increased.

[0064] Since the extension and contraction amount of the electric cylinder 81 is positively correlated with the speed change of the conveyor 2, that is to say, the device can dynamically adjust the amount of cast aluminum liquid according to the conveying speed of the copper belt 21, so that the aluminum liquid can be evenly attached to the copper belt 21.

[0065] When the diverter block 7 moves, the second flow channel 542 can complement the first flow channel 541 , so that the flow rate of the aluminum liquid in the diverter trough 5 remains unchanged, thereby preventing the semi-molten aluminum liquid from solidifying in the diverter trough 5 .

[0066] When the conveying speed of the copper strip 21 reaches the maximum value, the electric cylinder 81 moves the diverter block 7 to the leftmost position. Under the action of the rack 85, the gear 84 rotates and overcomes the resistance between the sliding shaft 71 and the rotating sleeve 831, so that the diverter block 7 rotates to an inclined state, so that the upper and lower ends of the straight surface 73 are respectively connected to the second inner arc surface 571 and the fourth inner arc surface 552, so that the aluminum liquid smoothly enters the first diverter pipe 51 from the first flow channel 541 and is discharged downward.

[0067] When the conveying speed of the copper belt 21 decreases, the diverter block 7 rotates back to the initial state, so that the straight surface 73 is horizontally downward, and the outer arc surface 72 is used to guide the aluminum liquid into the first flow channel 541 and the second flow channel 542 on both sides.

[0068] When the copper belt 21 stops moving, the diverter block 7 moves to the rightmost position, allowing the aluminum liquid to flow into the recovery furnace 6 along the second flow channel 542 and the second diverter pipe 52, so that the aluminum liquid can be discharged smoothly, avoiding the aluminum liquid from solidifying in the diverter tank 5.

[0069] The filtrate in the recovery furnace 6 can be returned to the insulation furnace 4 through the recovery pipe 61 to achieve recycling.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
