Technical Field

[0001] The present invention belongs to the field of new energy technologies, and specifically relates to a method for manufacturing a copper-aluminum composite pole plate material.

Background Art

[0002] The plate material of the copper-aluminum composite pole is a composite material that combines the excellent properties of two metals, copper and aluminum. Copper has good electrical conductivity, corrosion resistance, oxidation resistance, and high heat capacity, and aluminum has the characteristics of light specific gravity and low density. Therefore, in the process of manufacturing the plate material of the copper-aluminum composite pole, an important technology is how to achieve an effective composite of copper and aluminum while maintaining their respective excellent properties.

[0003] The Chinese patent application with the publication number CN109616607B discloses a forming method of a copper-aluminum composite pole, which includes supplying copper bar materials and aluminum bar materials respectively to obtain copper bars and aluminum bars, pressing the copper bars and aluminum bars respectively to obtain copper conductive sheets and aluminum conductive sheets respectively, aligning the bottoms of the copper conductive sheet and the aluminum conductive sheet and welding them together integrally to obtain a copper-aluminum composite pole, washing the copper-aluminum composite pole, pressing it, and moving the material.

[0004] In the prior art, when only pressing the copper conductive sheet and the aluminum conductive sheet obtained by re-pressing to move the material, it flows around along the copper positioning holes and the aluminum positioning holes to move the material uniformly and stabilize the structures of the copper conductive sheet and the aluminum conductive sheet. However, the copper conductive sheet and the aluminum conductive sheet have not been specifically analyzed to obtain the influence on the manufacturing of the copper-aluminum composite pole, nor has the performance of the copper-aluminum composite pole been analyzed to determine whether the obtained copper-aluminum composite pole meets the standard.

[0005] Therefore, the present invention provides a method for manufacturing a copper-aluminum composite pole plate material. [Overview of the Initiative]

[0006] To compensate for the shortcomings of conventional technologies, this technology solves at least one technical problem proposed in the background technology.

Step 2 involves roughening and cleaning the copper strip to complete the surface pretreatment of the copper strip, Step 3 involves continuous casting of aluminum strips into the aluminum solution after it has been allowed to stand, Step 4 involves forming the aluminum boss of the pole column using forming rolls to increase the copper-aluminum bonding strength and discharging the aluminum waste to the side. Step 5 involves pressing at room temperature to form the fine features of the roll-rolled boss and shape the larger boss, The process includes step 6, which involves supplying material to the electrode poles and determining whether the battery electrode pole product meets the standards. The standard judgment value Q for aluminum-copper in the forming warm rolling roll poles is compared with a preset standard judgment threshold for aluminum-copper in the forming warm rolling roll poles, and the comparison process is as follows. If the standard judgment value Q for aluminum-copper in the forming warm rolling roll pole is equal to or greater than the preset standard judgment threshold for aluminum-copper in the forming warm rolling roll pole, then the aluminum-copper in the forming warm rolling roll pole meets the standard.

[0022] To facilitate understanding of the technical means, creative features, objectives, and effects realized by the present invention, the present invention will be further described below by combining specific embodiments.

[0023] Example 1 As shown in Figures 1 to 3, the method for manufacturing a copper-aluminum composite pole plate material according to an embodiment of the present invention includes the following steps.

[0024] In step 1, the aluminum ingot is heated to 700°C and melted, and the aluminum ingot liquid at 700°C is allowed to stand for 5 minutes to obtain an aluminum solution.

[0025] In Step 1, the aluminum ingot liquid at 700°C is allowed to stand for 5 minutes to obtain an aluminum solution, and the quality of the aluminum solution is evaluated.

[0026] In A1, the fluidity of the aluminum solution after standing was detected, and a representative value of the aluminum solution's fluidity was obtained. The specific process is as follows:

[0027] In A101, a portion of the aluminum solution is extracted and divided into multiple groups of equal amounts of aluminum solution, and a representative viscosity value is obtained for each of the multiple groups of equal amounts of aluminum solution.

[0028] In A102, the viscosity representative values ​​of equal amounts of aluminum solutions from multiple groups are added together to obtain the average value, and this average value is used as the viscosity determination value for the solution.

[0029] In A103, processing is performed based on the viscosity determination value of a portion of the extracted solution, and a representative flow value E of the aluminum solution is obtained using the formula E = M × α, where M represents the viscosity determination value of the solution and α represents a predetermined ratio coefficient.

[0030] In A2, the gas content of the aluminum solution after standing was detected, and a representative value of the gas content of the aluminum solution was obtained. The specific process is as follows:

[0031] In A201, the density of the aluminum solution after standing is obtained.

[0032] In A202, the difference between the density of the aluminum solution after standing and the standard density of the aluminum solution is determined, and this difference is taken as the density deviation value of the actual aluminum solution.

[0033] In A203, the ratio of the density deviation value of the actual aluminum solution to the standard density of the aluminum solution is used as the representative value of the gas content of the aluminum solution.

[0034] Specifically, the representative value R of the gas content of the aluminum solution is obtained from the following formula, where F represents the standard density of the aluminum solution, U represents the density of the aluminum solution after standing, and β represents a predetermined ratio coefficient.

The specific process is as follows:

[0036] In A301, the quality determination value W of the aluminum solution is obtained using the following formula, based on the representative flow value E of the aluminum solution and the representative gas content value R of the aluminum solution, where ε represents a predetermined ratio coefficient.

number

[0037] In A302, the quality judgment value W of the aluminum solution is compared with a pre-set quality judgment threshold for the aluminum solution, and the specific comparison process is as follows.

[0038] If the quality judgment value W of the aluminum solution is equal to or greater than the preset quality judgment threshold for the aluminum solution, the aluminum solution is judged to be of high quality.

[0039] If the quality judgment value W of the aluminum solution is smaller than the preset quality judgment threshold for the aluminum solution, the aluminum solution is judged to be of low quality.

[0040] In step 2, the copper strip is roughened and cleaned to complete the surface pretreatment of the copper strip.

[0041] In Step 2, the roughened and cleaned copper strips are processed to obtain the surface flatness value of the copper strips. The specific process is as follows:

[0042] In B1, the copper strip surface after roughening and cleaning is detected, and flatness values ​​are obtained at different locations on the copper strip surface.

[0043] In step B2, the copper strips are sorted based on their flatness values ​​at different locations on the surface, and the mode of the flatness values ​​at different locations on the copper strip surface is obtained.

[0044] In B3, based on the mode of the flatness values ​​at different locations on the surface of the copper strip, the difference between the flatness values ​​at different locations on the surface of the copper strip and the mode of the flatness values ​​is calculated, and the value of this difference is taken as the deviation score of the flatness at different locations on the surface of the copper strip.

[0045] In B4, the deviation values ​​of the flatness at different locations on the copper strip surface are added together to obtain the average value, and this average value is used as the deviation coefficient of the flatness at different locations on the copper strip surface.

[0046] In B5, the representative value K of the flatness of the copper strip surface is obtained using the formula K = T × ω, where T represents the mode of the flatness values ​​at different locations on the copper strip surface, and ω represents the flatness deviation coefficient at different locations on the copper strip surface.

[0047] In step 3, continuous casting of aluminum strips is performed on the aluminum solution after it has been allowed to stand.

[0050] In C2, the aluminum strips are sorted based on the flatness values ​​at different locations on their surface, and the flatness values ​​at different locations on the surface of the aluminum strips are obtained.

[0051] In C3, the flatness values ​​at different locations on the surface of the aluminum strip are added together to obtain an average value, and this average value is taken as the representative flatness value L for different locations on the surface of the aluminum strip.

[0052] Specifically, the continuous casting speed is 200 mm / min, the casting width is 10 mm, and the casting thickness is 3 mm.

[0053] The technical proposal for an embodiment of the present invention is as follows: By detecting and sorting the flatness values ​​at different locations on the surface of an aluminum strip after continuous casting, the flatness values ​​at different locations on the surface of the aluminum strip are obtained. Based on the flatness values ​​at different locations on the surface of the aluminum strip, an average value is calculated by adding them together. This average value is used as the representative value L for the flatness at different locations on the surface of the aluminum strip. The flatness of the surface of the aluminum strip is represented using this representative value L. By calculating the average value of the flatness at different locations and using it as the representative value for the flatness at different locations on the surface of the aluminum strip, abnormal fluctuations and errors in the flatness value data at different locations can be avoided by using the average value, and the flatness data of the surface of the aluminum strip can not be excessively affected.

[0054] In step 4, the aluminum boss of the pole column is formed by forming rolls to increase the copper-aluminum bonding strength, and the aluminum waste is discharged to the side.

[0055] Specifically, roll rolling includes cold rolling and warm rolling, and generally the warm rolling temperature is 300°C. Warm rolling also reduces the amount of deformation of the copper.

[0056] As shown in Figure 4, in step 4, stress tolerance detection is performed on the aluminum-copper pole column of the forming warm rolling roll to obtain a representative stress tolerance value.

[0057] In D1, stress tolerance detection is performed on different positions of aluminum-copper in the forming warm rolling roll poles, and stress tolerance values ​​are obtained at these different positions.

[0058] In D2, the squared difference is calculated by adding the allowable stress values ​​of aluminum-copper at different positions on the forming warm rolling roll pole, and this squared difference is taken as the representative allowable stress value of aluminum-copper on the forming warm rolling roll pole.

[0059] In step 5, pressing is performed at room temperature to shape the fine features of the roll-rolled boss and to shape the larger boss.

[0060] In step 6, material is supplied to the electrode poles, and it is determined whether the battery electrode pole products meet the standards.

[0061] In step 6, processing is carried out based on the representative flatness value K of the copper strip surface, the representative flatness value L of different positions on the aluminum strip surface, and the representative allowable aluminum-copper stress of the forming warm rolling roll poles. The specific processing steps are as follows.

[0063] Specifically, the representative resistance value V of the aluminum-copper electrode column of the forming warm rolling mill is obtained by V = lg(K + L) × h, where h represents a predetermined ratio coefficient.

[0064] In S2, the aluminum-copper resistance value V and the aluminum-copper stress tolerance value of the forming warm rolling roll poles are used to obtain a standard judgment value for the aluminum-copper of the forming warm rolling roll poles.

[0065] In S2, the standard judgment value Q for aluminum-copper in the forming warm rolling roll pole is obtained using the following formula, where P represents the representative stress allowable value for aluminum-copper in the forming warm rolling roll pole, and θ represents a predetermined ratio coefficient.

number

[0066] Specifically, the standard judgment value Q for aluminum-copper in the forming warm rolling roll poles is compared with a preset standard judgment threshold for aluminum-copper in the forming warm rolling roll poles, and the comparison process is as follows.

[0067] If the standard judgment value Q for aluminum-copper in the forming warm rolling roll pole is equal to or greater than the preset standard judgment threshold for aluminum-copper in the forming warm rolling roll pole, then the aluminum-copper in the forming warm rolling roll pole meets the standard.
