Description

Technical Field

[0001] The invention relates to the technical field of metal plate and strip processing, in particular to a solid copper surface treatment device for continuous casting of copper-aluminum composite strips. Background Art

[0002] Copper-aluminum composite plate and strip material is a bimetallic composite material with aluminum as the matrix and copper as the cladding. Copper and aluminum are both important non-ferrous metals and have been widely used in industrial and civil fields. At present, the production of aluminum and copper composite metal plates and strips mainly adopts solid-solid composite method and liquid-solid composite method. The solid-solid composite method is mainly produced by explosive composite method, cladding welding method, composite ingot hot rolling method, and rolling and pressing method. When producing and processing by the above-mentioned methods, the copper strip needs to be surface treated.

[0003] The application number in the existing public technology is: CN201611256754.9 A method for producing a copper-aluminum composite plate and strip, and a copper-aluminum composite plate and strip. The production method of the copper-aluminum composite plate and strip of the present invention adopts a continuous production line to complete the process including hot-dip aluminum plating and cast rolling on the copper plate and strip to obtain a composite plate and strip blank, and then the aluminum-plated surface of the composite plate and strip blank is oxygen-free hot-rolled with the aluminum alloy plate and strip substrate to obtain; CN202110302931.7 A method for producing a copper-aluminum high-temperature composite, comprising the following steps: step (1), surface treatment of the copper strip; step (2), electroplating and texturing treatment; step (3), preparation of aluminum semi-solid slurry; step (4), heat treatment and annealing; step (5), cold rolling; CN201811511171.5 A surface treatment process of a copper alloy strip, comprising unwinding, corrosion inhibition-passivation treatment, surface cleaning treatment, surface curing treatment, and winding.

[0004] Combining the above patents with the existing copper surface treatment devices, it is not difficult to find that most of the existing treatment devices involve more components, resulting in a larger overall footprint, which is inconvenient for the transportation of the device and the subsequent installation and use, and the larger footprint is not conducive to the use of small sites, and it is impossible to arrange more treatment devices at the same time to perform operations, which limits the production efficiency of the factory. In addition, the processes are highly correlated and the structure is relatively simple. Once a step fails, the entire machine needs to be shut down for maintenance, which is time-consuming and labor-intensive to operate, resulting in the device being unable to continue production operations, reducing the use effect and production efficiency of the device, and the overall use effect is not very ideal.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Embodiment 1, refer to Figure 1-10The solid copper surface treatment device for continuous casting of copper-aluminum composite strips comprises a replacement base 1 and a treatment box 8.

The structure of the replacement box 6 is the same as the box structure inside the corresponding working chamber 11, which is convenient for subsequent replacement and use. In addition, an independent controller and a battery are provided inside each box, and the controller can be connected to an external control terminal via WiFi signals or wireless signals, which is convenient for subsequent centralized control. Since the controllers, batteries, wireless signals and WiFi signal generating equipment are mature in actual production and life, and can be easily obtained on the market, they will not be elaborated on.

[0043] Example 2, refer to Figure 1 , Figure 2 and Figure 3 Several groups of support plates 16 are evenly and symmetrically welded at the top position inside the processing box 8. Several groups of guide rollers 15 are rotatably connected between the support plates 16. The guide rollers 15 are staggered with each other. The guide rollers 15 are set to guide the copper strip, and the guide rollers 15 are grouped in pairs, and the upper and lower unknown guide rollers 15 are staggered. For example, if one group is on the left, the lower one is on the right, so as to bend the copper strip for transportation, expand the moving path, delay the retention time, and facilitate better surface treatment of the copper strip.

[0044] Example 3, refer to Figure 1 and Figure 6A plurality of first ultrasonic generators 30 are disposed on the inner surfaces of the oil removal tank 10 on both sides. The first ultrasonic generator 30 and the second ultrasonic generator 38 are both common ultrasonic generators, and therefore will not be described in detail.

[0045] Embodiment 4, referring to Figure 1 and Figure 7 A plurality of adjusting grooves 31 are symmetrically provided on the surfaces of both sides of the interior of the pickling box 18. A connecting shaft 33 is rotatably connected to the interior of the adjusting groove 31. One end of the connecting shaft 33 passes through one side of the pickling box 18 and is connected to a motor 34. A blade 32 is fixedly installed on the surface of the connecting shaft 33. Both the blade 32 and the connecting shaft 33 are made of materials that do not react with the HCl aqueous solution, such as plastic, to ensure that they can be used smoothly. The internal aqueous solution is stirred by the fluctuation of the blade 32 to ensure that the concentration of the aqueous solution is relatively balanced.

[0046] Example 5, refer to Figure 1 and Figure 8 Several groups of metal brushes 35 are evenly installed around the inner surface of the polishing box 19. The metal brushes 35 are provided to remove impurities and oxide scale on the surface of the copper strip to facilitate subsequent contact with aluminum materials and realize the processing of the copper-aluminum composite strip.

[0047] Example 6, refer to Figure 1 and Figure 6 Several groups of second ultrasonic generators 38 are evenly installed on the inner surface of the water washing box 20, and several groups of mounting plates 36 are evenly installed between the second ultrasonic generators 38 on the inner surface of the water washing box 20. Several groups of flushing nozzles 37 are evenly installed on the surface of the mounting plates 36. Water pumps 40 are symmetrically installed at the bottom of the two sides of the water washing box 20. Both ends of the water pump 40 are flange-connected to the bottom of the surface of the water washing box 20 and to the mounting plate 36 through a circulation pipe 39. A filter is provided at the contact position between the circulation pipe 39 and the water washing box 20. The filter is provided to filter solid impurities in the liquid to prevent the circulating liquid from damaging the water pump 40 and the copper belt, thereby ensuring the cleaning effect.

[0048] Embodiment 7, reference Figure 1 and Fig.10 Several groups of jet plates 41 are evenly installed on the surfaces of both sides of the drying box 21, and several groups of gas nozzles 42 are evenly installed on the surfaces of the jet plates 41. Blowers 43 are symmetrically installed at the bottom of both sides of the drying box 21. The blowers 43 are connected to the jet plates 41 through pipelines. External air can be introduced through the blowers 43 and sprayed out through the gas nozzles 42 to achieve the drying operation of the copper strip, which is convenient for subsequent use.

[0049] Embodiment 8, refer to Figure 1 , Fig. 9 and Fig.10 A cavity is provided inside the mounting plate 36 and inside the jet plate 41. The cavity is provided to facilitate the flow of liquid and gas, thereby achieving flushing and drying operations on the copper strip.

[0050] Embodiment 9, refer to Figure 1 The copper strip 24 to be processed is transported between the guide rollers 15. The copper strip 24 to be processed can be moved back and forth through the staggered guide rollers 15, thereby increasing the moving path and delaying the retention time, so as to better contact with the processing medium and improve the overall processing effect.

[0051] Embodiment 10, reference Figure 1 , legs 23 are symmetrically installed on both sides of the bottom of the replacement base 1, and a feed port 13 and a discharge port 22 are respectively opened at the top positions of the two side surfaces of the processing box 8. Feed rollers 14 are symmetrically connected to the inside of the feed port 13 and the inside of the discharge port 22 for rotation. The feeding rollers 14 are provided to guide and convey the copper strip 24 to be processed, which serves an auxiliary purpose, and the copper strip passing through the discharge port 22 is connected to the external traction equipment, which provides traction power through the external traction equipment, facilitates the movement of the copper strip, and enables the copper strip to undergo different processing operations.

[0052] Working principle: In actual use, the copper strip that needs to be surface treated can be added through the feed port 13, and finally discharged through the discharge port 22 on the other side. In the middle of passing through the feed port 13 and the discharge port 22, the copper strip will pass through a plurality of staggered guide rollers 15 in sequence, so as to guide the copper strip to bend back and forth for multiple times, so that the moving path of the copper strip in multiple groups of different boxes is increased, the retention time is prolonged, and the treatment is better carried out. The volume of the equipment can also be reduced, thereby compressing the overall floor space, facilitating better transportation and use of the device, so that the device can better adapt to the use of small areas, and multiple groups of devices can be set up at one time to improve the production efficiency of the factory, and then after the copper strip is adjusted After completion, it will first pass through the degreasing tank 10, and the degreasing agent inside the degreasing tank 10 can degrease the surface of the copper strip. At the same time, the first ultrasonic generator 30 inside can generate ultrasonic agitation, so that the degreasing agent can more fully contact the surface of the copper strip, thereby improving the overall degreasing effect. Then, the degreased copper strip will be transported to the inside of the pickling tank 18, and the 10% HCl aqueous solution inside can be used to pickle the surface of the copper strip. During pickling, the multiple motors 34 on the side of the pickling tank 18 can drive the connecting shaft 33 to rotate, thereby driving the blades 32 connected to the connecting shaft 33 to rotate up and down, so as to flip the internal HCl aqueous solution up and down, so that the concentration of HCl at different positions It can be relatively balanced to ensure that the pickling effect at different positions on the surface of the copper strip is relatively consistent, and prevent the upper HCl aqueous solution from coming into contact with the copper strip first, while the oxidation degree of the copper strip surface is more serious at this time, which will cause the aqueous solution to be used in large quantities, and then there will be a difference in solubility with the HCl aqueous solution below. Then, after the pickling of the copper strip is completed, the copper strip will enter the polishing box 19, and the metal brushes 35 densely distributed on both sides of the interior can remove impurities on the surface of the copper strip and remove the oxide skin that has not been removed cleanly, so as to facilitate the subsequent processing with aluminum materials to realize the production operation of the copper-aluminum composite strip. Next, after the polishing is completed, the copper strip will enter the water washing box 20, and the cleaning water can be excited by the second ultrasonic generator 38 inside. The copper strip is swung to better remove the debris remaining on the surface of the copper strip, thereby improving the cleanliness of the surface of the copper strip. The installed water pump 40 and the circulation pipe 39 can continuously extract the internal water source and spray it through the flushing nozzle 37, so that the internal liquid flows, so that the cleaning water can better contact with the copper strip, thereby improving the treatment effect of the copper strip. Then the cleaned copper strip can enter the drying box 21, and the gas sprayed by the gas nozzles 42 on both sides of the inside can air-dry the copper strip, which is convenient for subsequent use. Moreover, the multiple boxes used for surface cleaning are all detachable independent structures. Therefore, when damage or failure occurs and maintenance is required, the motor 28 at the corresponding position can drive the screw 27 to rotate.Then, the downward movement operation of the carrying plate 7 is realized. At this time, the boxes on the top of the carrying plate 7, such as the oil removal box 10, the pickling box 18, etc., can fall down accordingly. Since the copper belt 24 to be processed is transported along multiple guide rollers 15 before the operation, the copper belt 24 to be processed will be in a suspended state. At this time, the copper belt can be moved slowly by controlling the running speed of the equipment that pulls the copper belt 24 to be processed from the outside. At this time, when the carrying plate 7 falls to the bottom end of the replacement chamber 3, the box that needs maintenance can be ejected by the ejection of the second hydraulic rod 25 on the side of the carrying base 4, and then the intact replacement box 6 can be pushed out by the push of the first hydraulic rod 5 on the other side. The copper strip is sent to the carrier plate 7, and the structure of the replacement box 6 is the same as the structure of the box body it faces, so it can be used directly after replacement. After the replacement box 6 moves to the carrier plate 7, the carrier plate 7 can be moved up by reversing the motor 28, and then the replacement box 6 is moved to the inside of the processing box 8. At this time, the copper strip will be wrapped inside the replacement box 6 again, and then the surface treatment operation of the copper strip will continue. The whole replacement process does not require shutdown, which can effectively ensure the continuity and efficiency of the operation. At the same time, less personnel are involved, which can reduce the labor intensity of personnel and ensure the safety of personnel. The overall device has the advantages of compact structure, small footprint, convenient fault replacement, replacement during operation, and good cleaning effect.

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.
