Description

Technical Field

[0001] The invention relates to the technical field of copper-aluminum composite plate production, and in particular to a solid-liquid layered copper-aluminum composite plate strip preparation production device and method. Background Art

[0002] At present, in the preparation of copper-aluminum composite plates and strips, continuous casting is mostly used to produce copper-aluminum composite plates and strips, which can effectively improve production efficiency and reduce the generation of oxide slag.

[0003] Patent publication number CN118385539B discloses a device and process for preparing pole raw materials by continuous casting. This prior art realizes the integrated continuous preparation of copper-aluminum composite strips, eliminating the need to separately process the copper strips and aluminum liquid, thereby improving the preparation efficiency.

[0004] However, the above prior art has the following technical defects: 1. In order to prevent aluminum from falling on the copper strip and causing the strip to be out of position during the adding process, this prior art requires that the copper strip adding position be adsorbed on the surface of the supporting inner frame to prevent the copper strip from being out of position during the adding process. However, at this time, the copper strip needs to stop moving forward, and the copper strip is in an intermittent forward mode on this device. This forward mode is slow, which leads to low preparation efficiency of the device.

[0005] Second, the prior art adds aluminum simply by discharging it onto the upper surface of the copper strip through the casting nozzle. Since the aluminum liquid is in a semi-molten and semi-solid state, this method of addition can easily cause the aluminum material to pile up on the copper strip and distribute unevenly, which ultimately leads to different thicknesses of the aluminum layer of the cast-rolled copper-aluminum composite strip, reducing the quality of the finished product.

[0006] In summary, the prior art still has room for improvement in terms of improving the production efficiency of the device and the quality of the finished product. Therefore, technical personnel in this field have proposed a device that can limit and fix the copper strip as it continues to move forward and make the aluminum liquid more evenly distributed.

[0040] The following combination Figure 1 - Fig.13 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a solid-liquid layered copper-aluminum composite plate and strip preparation and production device and method. Through the cooperation of a conveying mechanism and a fixing mechanism, a plurality of suction cups on the fixing mechanism are allowed to move around the rotating trajectory of the conveyor belt, and the fixing mechanism is used in conjunction with a Z-shaped limit rail and a G-shaped limit rail to allow a plurality of movable suction cups on the inner side to adsorb and fix the advancing copper plate and strip, thereby achieving limited fixation of the feeding area of ​​the copper plate and strip during its advancement, and the copper plate and strip is always in an advancing state, replacing the previous intermittent advancing method, thereby increasing the advancing speed of the copper plate and strip and enhancing the production efficiency of the device.

[0042] Embodiment 1: like Figure 1 and Figure 2As shown, it includes a long strip base 1, a conveying roller 8 is rotatably arranged above the base 1, and a discharge mechanism 6 and a rolling mechanism 7 are respectively arranged on one side of the conveying roller 8. The conveying roller 8 is used to support and convey the copper plate strip, the discharge mechanism 6 is used to add semi-solid aluminum liquid to the upper surface of the copper plate, and the rolling mechanism 7 is used to roll the copper plate strip after adding the aluminum liquid to roll it into a copper-aluminum composite plate strip.

[0043] like Figure 3 As shown, the discharge mechanism 6 includes two symmetrically arranged mounting frames 601, a storage tank 602 is installed on the upper side of the mounting frame 601, and an opening is opened on the lower side of the storage tank 602. The high-temperature molten aluminum liquid is put into the storage tank 602 through the input end, and then stands in the storage tank 602 to become a semi-molten plate solid state.

[0044] like Figure 3 As shown, a distribution tube 603 matching with it is installed at the open end, and two discharge electric cylinders 604 are symmetrically installed on the side of the distribution tube 603 near the bottom, and the ends of the two discharge electric cylinders 604 are jointly installed with a baffle 605 for blocking the lower end of the distribution tube 603. The extension of the discharge electric cylinder 604 drives the baffle 605 to move to open the lower end of the distribution tube 603, and then the distribution tube 603 in the storage tank 602 falls on the upper surface of the copper plate strip in a flat shape through the guidance of the distribution tube 603, so as to realize the addition of aluminum material.

[0045] like Figure 4 As shown, the rolling mechanism 7 includes a C-shaped seat 701 installed on a base 1, and two motors 702 are symmetrically installed on the side of the C-shaped seat 701. The driving end of the motor 702 is installed with a roller 703 that is rotatably connected to the inner side of the C-shaped seat 701. The two motors 702 drive the two rollers 703 to rotate in opposite directions. The copper plate with aluminum material added on the upper surface passes between the two rollers 703 and is cast-rolled to obtain a copper-aluminum composite plate and strip.

[0046] like Figure 5 and Figure 6 As shown, a conveying mechanism 2 is arranged on the upper side of the base 1, and the conveying mechanism 2 includes two symmetrically arranged U-shaped frames 201, and two conveying wheels 202 are rotatably installed on the lower side of the conveying wheel 202, and a conveyor belt 203 is commonly arranged on the two conveying wheels 202. A motor 204 with a driving end fixedly connected to one of the conveying wheels 202 is installed on the upper side of the U-shaped frame 201, and the running motor 204 drives the conveying wheel 202 connected thereto to rotate, and the rotating conveying wheel 202 cooperates with the other conveying wheel 202 to drive the conveyor belt 203 to rotate.

[0047] like Figure 5 , Figure 7 and Figure 8As shown, a fixing mechanism 3 is arranged on the conveyor belt 203, and the fixing mechanism 3 includes a plurality of evenly distributed U-shaped plates 301, each of which is provided with a cylinder 306, and a suction cup 307 is installed on the upper side of the cylinder 306. The rotating conveyor belt 203 drives all the suction cups 307 to move around its track, and at the same time, the moving suction cups 307 are used to support the advancing copper plate belt.

[0048] like Figure 7 and Figure 8 As shown, a piston 308 matching with the cylinder 306 is slidably arranged inside the cylinder 306, a secondary spring 310 is arranged below the piston 308 inside the cylinder 306, and an annular magnet 309 is arranged at the center of the bottom surface of the cylinder 306. When the piston 308 descends, the secondary spring 310 is compressed until the piston 308 and the annular magnet 309 are adsorbed. At the same time, the descending piston 308 draws the air in the suction cup 307 into the cylinder 306, so that negative pressure is generated inside the suction cup 307, thereby fixing the copper strip on the multiple moving suction cups 307 to avoid the copper strip from being dislocated during the process of adding aluminum material.

[0049] like Figure 7 and Figure 8 As shown, the lower end of the piston 308 extends to the outside of the cylinder 306 and is installed with a lower L-shaped plate 311. A Z-shaped limit rail 11 is installed on the upper side of the base 1 on one side of each conveying mechanism 2. A J-shaped limit rail 12 matching it is arranged on one side of the Z-shaped limit rail 11. A slider 312 matching the Z-shaped limit rail 11 and the J-shaped limit rail 12 is installed on the side of the lower L-shaped plate 311. After the moving slider 312 enters the Z-shaped limit rail 11, the slider 312 is guided by the Z-shaped limit rail 11 to descend, thereby driving the piston 308 to descend through the lower L-shaped plate 311. When the slider 312 enters the J-shaped limit rail 12, the slider 312 is guided to descend by the guidance. When it is about to leave, the slider 312 is guided by the J-shaped limit rail 12 to rise, thereby driving the piston 308 to rise and release the adsorption of the suction cup 307 and the copper plate strip.

[0050] In summary, the rotating conveyor belt 203 drives each suction cup 307 thereon to move around its track. When the slider 312 contacts the Z-shaped limit rail 11, it is guided down by the Z-shaped limit rail 11, and then the descending slider 312 drives the piston 308 to descend through the lower L-shaped plate 311, compressing the secondary spring 310 until the piston 308 is adsorbed by the annular magnet 309. At the same time, the descending piston 308 draws the air in the suction cup 307 into the cylinder 306, so that negative pressure is generated inside the suction cup 307, thereby fixing the copper plate strip on the multiple moving suction cups 307. , to avoid the copper strip from being out of position during the process of adding aluminum material, the above operation will also be performed when the slider 312 enters the Ji-shaped limit rail 12. When it is about to move out of the Ji-shaped limit rail 12, the slider 312 will rise through the Ji-shaped limit rail 12. The rising slider 312 drives the piston 308 to rise through the lower L-shaped plate 311, pushing the gas back into the suction cup 307, releasing the fixation between the suction cup 307 and the copper strip, and realizing the limited fixation of the copper strip during the forward movement of the copper strip, thereby avoiding the copper strip from being out of position due to vibration during the process of adding aluminum material.

[0051] like Figure 7 and Figure 8 As shown, a slide 303 is slidably provided on the side of the C-shaped plate 301, an upper L-shaped plate 305 connected to a cylinder 306 is installed on the side of the slide 303, a vertical rod 302 penetrating the slide 303 is installed between the inner side surfaces of the C-shaped plate 301, a main spring 304 is connected between the lower side of the slide 303 and the C-shaped plate 301, the descending suction cup 307 drives the slide 303 to descend through the cylinder 306 and the upper L-shaped plate 305, and the descending slide 303 compresses the main spring 304.

[0052] like Figure 7 and Fig. 9 As shown, a driving mechanism 4 is also installed on the fixing mechanism 3, and the driving mechanism 4 includes a driving electric cylinder 405, and a fixing seat 406 is installed on the upper end of the driving electric cylinder 405. A fixed gear 407 is rotatably installed in the fixing seat 406, and two fixed racks 408 meshing with the fixing gear 407 are slidably arranged around the fixing gear 407. The lifting and lowering of the driving electric cylinder 405 can drive the fixing seat 406 to lift and lower. When one fixed rack 408 moves, it will drive the other fixed rack 408 to move in the opposite direction through the fixed gear 407.

[0053] like Figure 5 and Fig. 9As shown, an annular adjustment track 10 is arranged around the transmission mechanism 2, and a limit block 402 is slidably arranged on one side of each driving electric cylinder 405 on the adjustment track 10, and an L-shaped frame 401 is installed at the end of the limit block 402. Two limit rods 403 extending into the upper cylinder 306 are symmetrically installed on the upper side of the L-shaped frame 401. The movable fixing mechanism 3 drives the limit block 402 to slide on the adjustment track 10. When the piston 308 descends until it contacts the limit rod 403, the piston 308 is separated from the annular magnet 309 due to its limit, and the compressed secondary spring 310 rebounds to drive the piston 308 to restore its position.

[0054] like Figure 8-Figure 10 As shown, a slot is provided on the side of the upper L-shaped plate 305, and a trapezoidal block 411 extending to the outside of the driving electric cylinder 405 is installed at one end of each fixed rack 408, and the trapezoidal block 411 on the same side of the slot extends into the slot. A return spring 410 is provided on one side of one of the clamps 409 inside the fixed seat 406, and an extrusion block 412 adapted to the trapezoidal block 411 is installed on the side of the L-shaped frame 401. When the fixed seat 406 descends, the inclined surface of the trapezoidal block 411 will squeeze the extrusion block 412, so that the trapezoidal block 411 enters the fixed seat 406, and the other trapezoidal block 411 is driven to move out of the slot through the cooperation of the fixed gear 407 and the two fixed racks 408, thereby releasing the fixation between the fixed seat 406 and the upper L-shaped plate 305.

[0055] like Figure 5 As shown, two electric push rods 9 connected to the L-shaped frame 201 are symmetrically installed on the adjustment track 10. The height of the adjustment track 10 can be adjusted by raising and lowering the electric push rods 9. At the same time, the raised and lowered adjustment track 10 drives the limit rod 403 and the extrusion block 412 to rise and fall through the L-shaped frame 401 and the limit block 402 to adjust the descending height of the cylinder 306.

[0056] like Figure 2 , Figure 5 and Fig. 9 As shown, an infrared receiver 404 is installed on one side of each driving electric cylinder 405 on the U-shaped plate 301, and two infrared transmitters 13 are symmetrically installed on the upper side of the base 1 between the Z-shaped limit rail 11 and the Y-shaped limit rail 12. A controller is also installed on the base 1. The infrared transmitter 13 emits infrared light upward. When the infrared receiver 404 moves to the top of the infrared receiver 404, it receives the infrared light and sends a signal to the controller. The controller controls the driving electric cylinder 405 corresponding to the infrared receiver 404 to shorten.

[0057] In summary, when the infrared receiver 404 moves to the position directly above the infrared receiver 404, it receives infrared light and sends a signal to the controller. The controller controls the corresponding driving cylinder 405 of the infrared receiver 404 to shorten. The shortening of the driving cylinder 405 drives the fixing seat 406 to descend. The descending fixing seat 406 drives the cylinder 306 and the components thereon to descend through the upper L-shaped plate 305, compressing the infrared receiver 404. At this time, the suction cup 307 is adsorbed on the copper strip, and the descending suction cup 307 drags the adsorption part of the copper strip to descend. When the piston 308 descends until it contacts the limit rod 403, the piston 308 is separated from the annular magnet 309 due to its limit, compressing the infrared receiver 404. The compressed secondary spring 310 rebounds and drives the piston 308 to restore its position, releasing the adsorption between the suction cup 307 and the copper strip. At this time, the corresponding part of the copper strip vibrates due to the release of the pulling, and the aluminum material above the strip is evenly distributed through the vibration. At the same time, the piston 308 is separated from the annular magnet 309, the inclined surface of the trapezoidal block 411 on the fixed seat 406 squeezes the extrusion block 412, allowing the trapezoidal block 411 to enter the fixed seat 406, and the other trapezoidal block 411 is driven to move out of the slot through the cooperation of the fixed gear 407 and the two fixed racks 408, thereby releasing the fixation between the fixed seat 406 and the upper L-shaped plate 305, and the main spring 304 rebounds and drives the cylinder 306 to restore its position.

[0058] When the fixing seat 406 rises, the upper L-shaped plate 305 squeezes the inclined surface of the trapezoidal block 411 on the same side, pressing it into the fixing seat 406, and compressing the return spring 410 at the same time until the trapezoidal block 411 is aligned with the slot, and the return spring 410 rebounds to drive the trapezoidal block 411 to be reinserted into the slot.

[0059] Embodiment 2: Based on the first embodiment, Figure 5 , Fig.11 and Fig.12 As shown, a pushing mechanism 5 is arranged on the U-shaped frame 201, and the pushing mechanism 5 includes two symmetrically arranged mounting plates 501, between which a pinion 503 is rotatably mounted, and a driving rack 504 made of iron which is meshed with the pinion 503 and is slidably arranged on the side of the pinion 503, can drive the pinion 503 to rotate when the driving rack 504 descends.

[0060] like Fig.11 and Fig.12As shown, an L-shaped seat 505 is commonly installed on the sides of the two mounting plates 501, an L-shaped frame 506 penetrating the L-shaped seat 505 is arranged on the side of the driving rack 504, a connecting rail 507 is installed at the lower end of the L-shaped frame 506, an electromagnet that is magnetically attracted to the driving rack 504 is installed at the upper end of the L-shaped frame 506, and a connecting block 508 that is compatible with the connecting rail 507 is installed on the side of the cylinder 306. When the moving cylinder 306 drives the connecting block 508 to enter the connecting rail 507, the descending cylinder 306 will drive the L-shaped frame 506 to descend through the connecting rail 507 and the connecting block 508. When the electromagnet is energized, the descending L-shaped frame 506 will drive the driving rack 504 to descend, and when it is not energized, the descending L-shaped frame 506 will not drive the driving rack 504 to descend.

[0061] like Fig.11 As shown, a pressure plate 509 is installed on the L-shaped frame 506 above the L-shaped seat 505, and a push spring 510 is connected between the pressure plate 509 and the L-shaped seat 505. The descending L-shaped frame 506 will press the push spring 510 down through the pressure plate 509, and when the push spring 510 rebounds, it will drive the L-shaped frame 506 to restore its position.

[0062] like Fig.12 and Fig.13 As shown, a large gear 502 is installed on the side of the small gear 503, and a lower gear 514 meshing with the large gear 502 is rotatably installed on the side of the mounting plate 501. The rotating small gear 503 drives the large gear 502 to rotate, and the rotating large gear 502 drives the lower gear 514 to rotate. Since the large gear 502 has more teeth than the lower gear 514, one rotation of the large gear 502 can drive the lower gear 514 to rotate multiple times.

[0063] like Fig.11 As shown, a push plate 513 is provided on one side of each U-shaped frame 201, and a cross bar 511 is installed on the side of each mounting plate 501. A moving block 512 fixedly connected to the push plate 513 on the same side is slidably provided on the cross bar 511, and the sliding push plate 513 can drive the moving block 512 to slide on the cross bar 511.

[0064] like Fig.13 As shown, a circular plate 515 is installed on the side of the lower gear 514, and a connecting rod 516 is rotatably installed on the side edge of the circular plate 515. An L-shaped rod 517 connected to the circular plate 515 is rotatably installed on the end of the connecting rod 516. The rotating lower gear 514 drives the circular plate 515 to rotate, and the rotating circular plate 515 drives the push plate 513 to shake left and right through the connecting rod 516 and the L-shaped rod 517, so that the two push plates 513 are used to push the aluminum liquid on the copper plate toward the center to avoid dispersion. This is suitable for operations where the upper surface of the copper plate strip is not fully covered with aluminum liquid.

[0065] In summary, when the upper surface of the copper strip is fully covered with molten aluminum, the electromagnet is powered off, and then the L-shaped frame 506 is disconnected from the driving rack 504, and when the cylinder 306 descends, the pushing mechanism 5 does not work.

[0066] When the upper surface of the copper strip is not full of molten aluminum, the electromagnet is energized, and the L-shaped frame 506 is connected to the driving rack 504. Then, when the moving cylinder 306 allows the connecting block 508 to enter the connecting rail 507, the driving cylinder 405 is shortened to drive the cylinder 306 to descend, pulling the copper strip and driving the driving rack 504 to descend. Then, when the cylinder 306 rises, it also drives the driving rack 504 to rise. The rising driving rack 504 drives the small gear 503 to rotate, and the rotating small gear 503 drives the large gear 502 to rotate. The rotating large gear 502 drives the lower gear 514 to rotate, and the rotating lower gear 514 drives the circular plate 515 to rotate. The rotating circular plate 515 drives the push plate 513 to shake left and right through the connecting rod 516 and the L-shaped rod 517, so that the two push plates 513 are used to push the molten aluminum on the copper plate toward the center to avoid dispersion.

[0067] The present invention also discloses a method for preparing a solid-liquid layered copper-aluminum composite strip, the method comprising the following steps: S1. Fix the copper plate. Use the conveying mechanism 2 to cooperate with the fixing mechanism 3 to limit and fix the copper plate strip during its advancement. Specifically, the rotating conveyor belt 203 drives the suction cups 307 thereon to move around its trajectory. The cleaned and heated copper plate strip is placed on the device and advanced. Its lower surface will contact the inner suction cup 307. When the slider 312 contacts the Z-shaped limiting rail 11, it is guided down by the Z-shaped limiting rail 11, and then the descending slider 312 drives the piston 308 to descend through the lower L-shaped plate 311, compressing the secondary spring 310 until the piston 308 is adsorbed by the annular magnet 309. At the same time, the descending piston 308 draws the air in the suction cup 307 into the cylinder 306, so that negative pressure is generated inside the suction cup 307, thereby fixing the copper plate strip on multiple moving suction cups 307 to prevent the copper plate strip from being dislocated during the addition of aluminum.

[0068] S2, adding aluminum material, adding semi-molten aluminum liquid to the limited and fixed position of the copper strip. Specifically, the high-temperature molten aluminum liquid is first put into the storage tank 602 through the input end, and then it is allowed to stand in the storage tank 602 to become a semi-molten solid state. Then the discharge cylinder 604 is extended to drive the baffle 605 to move to open the lower end of the distribution pipe 603. Then the distribution pipe 603 in the storage tank 602 is guided by the distribution pipe 603 and falls on the upper surface of the copper strip in a flat shape, thereby achieving the addition of aluminum material.

[0069] S3, copper plate pulling, through the cooperation of the fixing mechanism 3 and the driving mechanism 4, the copper plate strip with aluminum material added is pulled to make the corresponding part vibrate. Specifically, when the infrared receiver 404 moves to the top of the infrared receiver 404, it receives infrared light and sends a signal to the controller. The controller controls the driving electric cylinder 405 corresponding to the infrared receiver 404 to shorten. The driving electric cylinder 405 shortens and drives the fixed seat 406 to descend. The descending fixed seat 406 drives the cylinder 306 and the components thereon to descend through the upper L-shaped plate 305, compressing the infrared receiver 404. At this time, the suction cup 307 is adsorbed on the copper plate strip, and then the descending suction cup 307 pulls the adsorption part of the copper plate strip down. The piston 308 descends until it contacts the limit rod 403. Due to its limit, the piston 308 is separated from the annular magnet 309, and the compressed secondary spring 310 rebounds to drive the piston 308 to restore its position, releasing the adsorption between the suction cup 307 and the copper strip. At this time, due to the release of the pulling, the corresponding part of the copper strip vibrates, and the aluminum material above the strip is evenly distributed through vibration. At the same time, the piston 308 is separated from the annular magnet 309, the inclined surface of the trapezoidal block 411 on the fixed seat 406 squeezes the extrusion block 412, allowing the trapezoidal block 411 to enter the fixed seat 406, and through the cooperation of the fixed gear 407 and the two fixed racks 408, the other trapezoidal block 411 is driven to move out of the slot, and the fixation between the fixed seat 406 and the upper L-shaped plate 305 is released. The main spring 304 rebounds and drives the cylinder 306 to restore its position.

[0070] S4, re-adsorption, the copper strip is re-adsorbed and fixed through the J-shaped limit rail 12 and the fixing mechanism 3 until it moves out of the fixed range. Specifically, when the slider 312 enters the J-shaped limit rail 12, the slider 312 is lowered through the guidance of the J-shaped limit rail 12, and the copper strip is adsorbed by the suction cup 307. When it is about to move out of the J-shaped limit rail 12, the slider 312 is raised through the guidance of the J-shaped limit rail 12. The rising slider 312 drives the piston 308 to rise through the lower L-shaped plate 311, pushing the gas back into the suction cup 307, and releasing the fixation between the suction cup 307 and the copper strip.

[0071] S5, plate and strip casting and rolling, using the rolling mechanism 7 to cast and roll the copper plate and strip with aluminum material added on the upper surface. Specifically, two motors 702 drive two rollers 703 to rotate in opposite directions. The copper plate with aluminum material added on the upper surface passes between the two rollers 703 and is cast and rolled to obtain a copper-aluminum composite plate and strip.

[0072] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.
