Description

Technical Field

[0001] This utility model relates to the field of copper wire technology, specifically to a copper wire for high-efficiency copper melting. Background Technology

[0002] The main purpose of using a crystallizer to extract molten copper is to transform liquid copper into solid copper products with a certain shape and size, such as plates or columns.

[0003] Copper products need to be placed in a copper dissolving tank for copper dissolution. This is done by immersing or spraying the copper products with copper sulfate solution. The purpose of dissolving copper is to increase the concentration of copper ions in the copper sulfate solution to a certain value, so as to meet the requirements of the foil production machine. In order to increase the dissolution rate of copper products in copper sulfate solution, the structure of the copper products needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a high-efficiency copper wire for copper melting, so as to solve the problems mentioned in the background section above.

[0005] This utility model is achieved through the following technical solution:

[0006] A high-efficiency copper wire for copper melting includes a copper wire drawn from a crystallizer, wherein the surface of the copper wire is formed with several grooves by stamping.

[0007] Furthermore, the cross-section of the copper wire is circular.

[0008] Furthermore, the cross-section of the groove is semi-circular.

[0009] Furthermore, the distance between two adjacent grooves is 2mm ± 0.2mm, and the diameter of the groove is 1mm ± 0.2mm.

[0010] Furthermore, the ratio of the diameter of the copper wire to the diameter of the groove is greater than or equal to 3:1.

[0011] Furthermore, the grooves are linearly arranged along the length of the copper wire, and the circumferential array of the grooves is formed on the outer circumferential surface of the copper wire.

[0012] Furthermore, the groove includes a semi-circular groove and a V-shaped groove, with several sets of the semi-circular grooves arranged linearly along the length of the copper wire, and the V-shaped grooves disposed between two adjacent sets of the semi-circular grooves.

[0013] Furthermore, the included angle of the V-groove is 70°-100°.

[0014] The beneficial effects of this utility model are as follows: a high-efficiency copper wire for copper melting includes a copper wire drawn from a crystallizer. The surface of the copper wire is formed with several grooves by stamping. When the copper wire just extends out of the crystallizer, it is relatively soft. Stamping the surface of the copper wire to form grooves can increase the surface area of ​​the copper material. By increasing the contact area, the copper melting rate can be accelerated, ensuring that the copper melting rate meets the requirements of the subsequent foil production machine.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Reference Figures 1 to 2 As shown, a high-efficiency copper wire for copper melting includes a copper wire 1 drawn from a crystallizer, and the surface of the copper wire 1 is formed with a plurality of grooves 11 by stamping.

[0021] Performing the stamping operation when the copper wire 1 has just emerged from the crystallizer and is still relatively soft facilitates the shaping of the copper wire 1's surface. At this stage, the copper wire 1 has good plasticity and is prone to plastic deformation, therefore the stamping process requires less force, making the processing relatively easier and more feasible. Furthermore, the stamping process does not require complex equipment and tools; ordinary stamping devices can complete the processing of the grooves 11 on the surface of the copper wire 1. This not only reduces equipment and maintenance costs but also improves the flexibility and adaptability of the production process.

[0022] By increasing the surface area of ​​copper wire 1, the copper dissolution rate can be accelerated, shortening the time required for the entire copper dissolution process. This allows for the processing of more copper material per unit time, thereby improving production efficiency. For large-scale industrial production, this can significantly increase capacity and production efficiency. Simultaneously, a higher dissolution rate and production efficiency mean that more copper foil can be produced per unit time, thus reducing production costs. Furthermore, the simple processing method and relatively low equipment and labor costs further reduce overall production costs.

[0023] The copper wire 1 has a circular cross-section, and the groove 11 has a semi-circular cross-section. According to the surface area formula, the surface area of ​​the circular copper wire 1 increases significantly after the semi-circular groove 11 is formed on its surface. This provides a larger contact area between the copper and the solution, making it easier for copper atoms to react with ions in the solution, thereby accelerating the copper dissolution process and meeting the copper ion concentration requirements of the foil-making machine. Furthermore, the semi-circular groove 11 is relatively smooth to process, without sharp edges, which reduces stress concentration. During the use and processing of the copper wire 1, stress concentration may lead to material fatigue and fracture; therefore, this design helps to improve the mechanical strength and service life of the copper wire 1.

[0024] The distance between two adjacent grooves 11 is 2mm ± 0.2mm, that is... Figure 2 The dimensions are shown in reference numeral B. The diameter of the groove 11 is 1mm ± 0.2mm, i.e. Figure 2 The dimensions are shown in reference numeral A. By satisfying the above parameters, relatively dense and appropriately sized grooves 11 can be formed on the surface of the copper wire 1. This design can maximize the surface area of ​​the copper wire 1 while ensuring the overall structural strength of the copper wire 1, thereby increasing the contact area between the copper and the solution and accelerating the dissolution rate of the copper.

[0025] The grooves 11 are linearly arranged along the length of the copper wire 1, and the circumferential array of the grooves 11 is formed on the outer circumferential surface of the copper wire 1. Through the above design, relatively dense and appropriately sized grooves 11 can be formed on the surface of the copper wire 1.

[0026] The ratio of the diameter of the copper wire 1 to the diameter of the groove 11 is greater than or equal to 3:1, that is... Figure 2 The dimensions of C:A. This is because the copper wire 1 needs to be wound into a coil to facilitate its placement in the copper melting pot. By satisfying the above relationship, the copper wire 1 will not break along the groove 11 during the winding process.

[0027] To facilitate winding the copper wire 1 into a coil, the groove 11 includes a semi-circular groove 111 and a V-shaped groove 112, see reference. Figure 2As shown, several sets of semi-circular grooves 111 are arranged linearly along the length of the copper wire 1, and the V-shaped grooves 112 are set between two adjacent sets of semi-circular grooves 111. This makes it easier to form folds at the V-shaped grooves 112 during the process of winding the copper wire 1 into a coil, thereby reducing the force required for bending and making the winding process smoother.

[0028] Reference Figure 2 As shown in angle D, the included angle of the V-groove 112 is 70°-100°. These angles are relatively easy to achieve during processing and avoid excessive stress concentration during the forming of the copper wire V-groove 112, which could lead to the copper wire 1 breaking.

[0029] In summary, measurements show that the present invention can increase the surface area of ​​copper material by approximately 10% through the setting of groove 11.
