DETAILED DESCRIPTION

[0031] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0032] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0034] like Figure 1-Figure 7 As shown, this embodiment provides a terminal forming module, comprising: a shearing mechanism 1, a first shaping mechanism 2, a beam forming mechanism 3, a head forming mechanism 4, a second shaping mechanism 5, a groove forming mechanism 6 and a flange forming mechanism 7 arranged in sequence according to a processing order, the shearing mechanism 1 is used to cut the material into workpieces of uniform length, the first shaping mechanism 2 flattens the cut workpiece, the beam forming mechanism 3 punches the flattened workpiece to form a beam portion 8 on the workpiece, the head forming mechanism 4 punches at the top of the workpiece to extrude the top of the workpiece into an arc shape, the second shaping mechanism 5 flattens the top of the workpiece, the groove forming mechanism 6 places the horizontally flipped workpiece, and punches the workpiece to form a groove 9, the flange forming mechanism 7 places the workpiece that is horizontally flipped again, and extrude the top of the workpiece so that the workpiece is deformed circumferentially under pressure and forms a flange portion 10, and a conical hole 11 is punched out on the flange portion 10.

[0035] Based on the above scheme, the raw material is first fed into a shearing mechanism 1, which cuts it into multiple workpieces of uniform length according to a preset length. This ensures the consistent dimensions of each terminal in subsequent processing steps. The cut workpieces may be slightly warped or uneven. A first shaping mechanism 2 performs a preliminary flattening treatment on these workpieces through mechanical or thermal treatment, laying a good foundation for the subsequent forming steps. The flattened workpieces are then fed into a tie rod forming mechanism 3, which stamps the tie rod portion 8 onto the workpiece. The tie rod portion 8 is a critical component of a power battery terminal, ensuring a secure connection between the terminal and the battery or other device. Next, the workpiece is fed into a head forming mechanism 4, which stamps the top of the workpiece into an arc shape. This design enhances the terminal's conductivity and mechanical strength. After the head is formed, the workpiece passes through a shaping mechanism again for flattening, ensuring the overall shape and dimensions of the terminal meet the design requirements. The workpiece is then flipped horizontally and fed into a groove forming mechanism 6. This mechanism stamps the workpiece to form a groove 9. The design of groove 9 facilitates a tight connection and positioning of the terminal with the battery. Finally, the workpiece is flipped horizontally again and fed into a flange forming mechanism 7, which squeezes the top of the workpiece, deforming it circumferentially and forming a flange portion 10. A tapered hole 11 is also stamped into flange portion 10, which serves as an interface for connecting to other components. By integrating multiple forming steps into a single module and arranging them sequentially according to the processing sequence, this module optimizes the entire production process. This not only reduces material handling and waiting time during the production process, but also reduces the error rate during the production process, thereby improving overall production efficiency. Because this module utilizes a precise forming mechanism and the entire production process is automated and continuous, it ensures that each terminal produced has highly consistent quality and dimensions, helping to improve the overall performance and reliability of the power battery. By reducing the risk of mold cracking or damage, this module reduces maintenance costs during the production process. Molds are critical equipment in the production process, and their stability and lifespan directly affect production efficiency and costs. The module's design reduces the risk of mold damage, thereby reducing the cost of maintenance and replacement. By optimizing the molding process and reducing unnecessary energy consumption, this module can reduce energy consumption and production costs, complying with the requirements of green manufacturing and sustainable development. Furthermore, because the module can adapt to the production needs of power battery terminals of different specifications and models, it has strong production flexibility. This allows manufacturers to quickly adjust production lines as needed to meet market changes and diverse customer demands, which is of great significance for improving production efficiency and responding to market changes.

[0036] Furthermore, if Figure 1As shown, the shearing mechanism 1 includes a shear core 101 and a pair of scissors 102. The shear core 101 is provided with a discharge cavity 103 for placing materials. The scissors 102 can move relative to the shear core 101 and shear the materials extending from the discharge cavity 103. The shear core 101 is a fixed component, and a discharge cavity 103 is defined within it. The size and shape of this discharge cavity 103 are designed to match the raw materials to be processed, so that the raw materials can be stably placed in the discharge cavity 103. The scissors 102 are a component that can move relative to the shear core 101, and their movement is usually achieved through mechanical or pneumatic drive. When the scissors 102 move, they approach the shear core 101 along a preset cutting line, and eventually cooperate with the shear core 101 to shear the raw materials extending from the discharge cavity 103. Since the discharge chamber 103 matches the size of the raw material, the raw material can remain stable before cutting, ensuring that the scissors 102 can cut according to the preset cutting line, thereby achieving a precise cutting effect. The drive mode of the scissors 102 is usually mechanical or pneumatic, which makes the operation easier and reduces the complexity and error of manual operation. The design of the shearing mechanism 1 can be adjusted according to different raw materials and processing requirements, such as changing the size and shape of the discharge chamber 103, or adjusting the shearing angle and force of the scissors 102 to adapt to the production requirements of power battery terminals of different specifications and models. Through automated cutting, the shearing mechanism 1 can quickly complete the cutting of raw materials, reducing the time and labor required for manual cutting, thereby improving production efficiency, and precise cutting helps to ensure that each workpiece has the same size and shape, thereby improving the quality stability and consistency of the product.

[0037] like Figure 2 As shown, the first shaping mechanism 2 includes a first main mold 201 and a first punch 202. The first main mold 201 is provided with a first shaping cavity 203. The first punch 202 is provided with a first punch 204, which corresponds to the first shaping cavity 203. During the terminal processing process, after the material is cut by the shearing mechanism 1, the cross-section may be cut or broken due to the shear force, resulting in a significant difference between the appearance of the cross-section and the appearance of the original material. This difference not only affects the appearance quality of the terminal but may also have an adverse effect on the terminal's performance. To eliminate this difference, the first shaping mechanism 2 plays a key role. After the workpiece is placed in the first shaping cavity 203, the first punch 202 begins to move downward, driving the first punch 204 into the shaping cavity to punch and shape the workpiece. The precisely designed first shaping cavity 203 and first punch 204 can accurately shape the cross-section of the workpiece, eliminating the appearance differences caused by the shear force, making the terminal's appearance more consistent and beautiful, and improving the terminal's performance stability.

[0038] like Figure 3 As shown, the beam forming mechanism 3 includes a second main mold 301 and a second punch 302. The second main mold 301 is provided with a first beam cavity 303. The second punch 302 is provided with a second punch 304. The second punch 304 corresponds to the position of the first beam cavity 303. After the workpiece is leveled by the first shaping mechanism 2, the surface may still have defects and be uneven, failing to meet the design requirements of the project. Therefore, an additional beam forming process is required to ensure that the surface appearance of the workpiece meets the requirements. When the workpiece is placed in the first beam cavity 303 of the second main mold 301, the second punch 302 begins to move downward, driving the second punch 304 to enter the beam cavity to stamp the workpiece. Through the precisely designed first beam cavity 303 and second punch 304, the workpiece can be accurately beam-formed, while eliminating possible surface defects and making the workpiece surface smoother and flatter. After the beam is formed, it is usually necessary to perform upsetting treatment on the outside of the beam. Upsetting treatment is to apply pressure on the workpiece to cause plastic deformation in a local area, thereby increasing the volume and density of the area. This process is crucial for the subsequent head forming step because it can make the head more uniform and full during forming, avoiding voids or defects.

[0039] In addition, if Figure 4 As shown, the head forming mechanism 4 includes a third main mold 401 and a third punch 402. The third main mold 401 defines a second rod-bearing cavity 403, and the third punch 402 defines a first forming cavity 404. A third punch 405 is positioned above the first forming cavity 404. The first forming cavity 404 corresponds to the second rod-bearing cavity 403, and the first forming cavity 404 is semicircular in shape. When the workpiece is accurately placed in the second rod-bearing cavity 403 of the third main mold 401, the third punch 402 begins to move downward. As the third punch 402 moves, the third punch 405 enters the first forming cavity 404 and punches the workpiece. This punching process forms a semicircular head structure under the combined action of the third punch 405 and the first forming cavity 404. The precise design of the third main mold 401 and the third punch 402, as well as their close fit, ensures accuracy during the head forming process, helping to reduce scrap and improve production efficiency. At the same time, in this step, the lower tie rod portion 8 also needs to be shaped to eliminate the sharp corners generated in the previous step.

[0040] In some embodiments, as Figure 5As shown, the second shaping mechanism 5 includes a fourth main mold 501 and a fourth punch 502. The fourth main mold 501 is provided with a third beam cavity 503, and the second punch 302 is provided with a second shaping cavity 504. A fourth punch 505 is positioned above the second shaping cavity 504. The second shaping cavity 504 corresponds to the position of the third beam cavity 503, and the bottom of the third beam cavity 503 is stepped. The third beam cavity 503 is provided on the fourth main mold 501, and the bottom of the beam cavity 503 is designed to be stepped. This design allows for more precise shaping of specific parts of the workpiece. At the same time, the fourth punch 502 is provided with a second shaping cavity 504, and a fourth punch 505 is positioned above it. When the workpiece is accurately placed in the third beam cavity 503 of the fourth main mold 501 after the head is formed, the fourth punch 502 begins to move downward. As the fourth punch 502 moves, the fourth punch 505 enters the second shaping cavity 504 to further stamp and shape the workpiece. This stamping process, under the combined action of the fourth punch 505 and the second shaping cavity 504, finely shapes the workpiece, ensuring that the shape, size, and appearance of the workpiece meet the design requirements. The stepped design at the bottom of the third beam cavity 503 allows certain parts of the workpiece to be stamped more accurately and forcefully, which helps to resolve some shape or size issues that may arise after the head is formed. Through this fine shaping, the overall quality and performance of the terminal can be further improved.

[0041] Furthermore, if Figure 6 As shown, the groove forming mechanism 6 includes a fifth main mold 601 and a fifth punch 602. The fifth main mold 601 is provided with a second forming cavity 603. The fifth punch 602 is provided with a fifth punch 604 protruding toward the side of the fifth main mold 601. The fifth punch 604 is provided with a fourth beam cavity 605. A sixth punch 606 is provided above the fourth beam cavity 605. Concave portions 607 are provided on both sides of the bottom of the fifth punch 604. The recesses 607 are provided on both sides of the bottom of the fifth punch 604. These recesses 607 are designed to form grooves 9 on specific parts of the terminal during the stamping process. At the same time, due to the presence of the recesses 607, the bottom of the terminal can also be shaped into a concave and convex shape. Such a design facilitates the forming of the elliptical flange in the next step. During the forming process of the elliptical flange, sometimes problems such as the narrow side of the ellipse is folded (i.e., the edge is uneven) and the wide side is not full are encountered. In order to solve this problem, the groove forming mechanism 6 hollows out a part of the material on both sides of the terminal so that the elliptical flange can be formed more evenly in the next process. This is because the hollowing operation reduces the resistance of the material during the stamping process, allowing the material to flow more evenly, thereby avoiding the problem of the narrow side of the ellipse fluttering and the wide side being unfull.

[0042] Furthermore, if Figure 7 As shown, the flange forming mechanism 7 includes a sixth main mold 701 and a sixth punch 702. The sixth main mold 701 is provided with a flange cavity 703. The sixth punch 702 is provided with a seventh punch 704. The seventh punch 704 has a tapered portion 705 protruding from one side of the flange cavity 703. During the stamping process, when the workpiece is accurately placed within the flange cavity 703 of the sixth main mold 701, the sixth punch 702 begins to move downward. As the sixth punch 702 moves, the tapered portion 705 of the seventh punch 704 begins to contact the workpiece and applies gradually increasing pressure. Due to the special shape of the tapered portion 705, it can punch a tapered hole in the workpiece. The shape and size of this hole match the tapered portion 705. The tapered hole 11 is designed to meet specific connection needs or process requirements. For example, in certain applications, the tapered hole 11 can provide better sealing performance or facilitate connection with other components. The entire stamping process is completed by the precise cooperation of the flange cavity 703 and the seventh punch 704, ensuring that the flange and tapered hole 11 formed on the workpiece are of high precision and high quality. This design not only improves the reliability and performance of the product, but also makes the terminal more stable and reliable during subsequent assembly and use.

[0043] It should be noted that the shape of the workpiece after being processed by the first shaping mechanism 2 is as follows: Figure 8 As shown, the shape of the workpiece after being processed by the beam forming mechanism 3 is as follows Figure 9 As shown, the shape of the workpiece after being processed by the head forming mechanism 4 is as follows Figure 10 As shown, the shape of the workpiece after being processed by the second shaping mechanism 5 is as follows Figure 11 As shown, the shape of the workpiece after being processed by the groove forming mechanism 6 is as follows Figure 12 As shown, the terminal shape after being processed by the steel pot flange forming mechanism 7 is as follows Figure 13 shown.

[0044] In addition, in the above processing steps, the material used is aluminum, that is, the aluminum terminal can be obtained by performing a series of processing on aluminum.
