Description

Technical Field

[0001] This application relates to the technical field of copper busbar production, and in particular to a copper busbar production process for connectors. Background Technology

[0002] A copper busbar, also known as a copper busbar or copper busbar, is a long conductor made of high-purity copper with a rectangular or rounded rectangular cross-section. Its main function is to transmit current and connect electrical equipment in a circuit.

[0003] The main production process of copper busbars is as follows: First, the copper billet is heated into a hot copper billet; then, the forming mold of the copper busbar is installed in a continuous extruder; next, the hot copper billet is placed in the continuous extruder, and the continuous extruder is started at the same time. The output end of the continuous extruder pushes the hot copper billet through the forming mold, so that the hot copper billet is formed into a copper busbar; finally, as the continuous extruder continues to push, the copper busbar comes out from the outlet of the continuous extruder, so that the copper busbar falls into the water tank at the outlet of the continuous extruder for cooling; after the copper busbar has cooled down, it can be taken out for use.

[0004] Reference Figure 1 and Figure 2 A U-shaped connector copper busbar is currently available. The structural features of this U-shaped copper busbar include: an arc segment diameter of 16.13 mm; a U-shaped opening width of 5.31 mm; a U-shaped body length of 36 mm; and symmetrical dovetail groove structures on both sides of the U-shaped opening's inner wall. Compared to the commonly used T-shaped, rectangular, or L-shaped copper busbar structures in the prior art, this special U-shaped copper busbar configuration presents the following technical challenges:

[0005] Because the forming mold requires a special mold core with a U-shaped opening inside the mold cavity, while the molds for conventional copper busbars in the existing technology do not require such a structure, the mold core is limited by the U-shaped opening width of only 5.31mm. The mold core thickness is forced to be designed to be the same size, resulting in insufficient mechanical strength of the mold core. As a result, when the hot copper billet passes through the mold at high speed during continuous extrusion production, the mold core of the forming mold is subjected to periodic impact loads, which easily leads to fatigue fracture. This results in a significant reduction in the service life of the mold. On average, the mold needs to be replaced every 5-8 batches of U-shaped copper busbars produced, which significantly increases production costs and downtime. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this application is to provide a connector copper busbar manufacturing process that improves mold lifespan and reduces production costs through structural optimization and process innovation.

[0007] The above-mentioned objective of this application is achieved through the following technical solution: a connector copper busbar manufacturing process, comprising the following steps: S1, pushing a hot copper blank into the extruder, so that the hot copper blank passes through a preliminary forming component, thereby forming a preliminary copper part;

[0008] S2. After the initial cooling of the copper parts, cut them to the predetermined length;

[0009] S3. The preliminary copper parts are formed into the target U-shaped copper busbar using a forming device.

[0010] Furthermore, in step S1, a forming mold with a V-shaped through groove is used as a preliminary forming component, so that the hot copper blank is formed into a V-shaped workpiece by passing through the forming mold.

[0011] Furthermore, step S3 also includes a sub-step S31, which includes the following steps:

[0012] S310, By placing a mold core that matches the U-shaped opening of the target U-shaped copper busbar in the V-shaped groove of the V-shaped workpiece;

[0013] S311. A V-shaped workpiece with a die core is stamped and deformed into a U-shaped copper busbar using a stamping machine.

[0014] Furthermore, S4, a pair of symmetrical dovetail grooves are cut on both sides of the U-shaped opening of the U-shaped copper busbar using a wire cutting machine.

[0015] Furthermore, S5, the formed U-shaped copper busbar is plated with a matte silver finish.

[0016] Furthermore, in step S5, the initial copper part is cut using a cutting machine. First, the dimensions are measured on the V-shaped workpiece according to the length of the U-shaped copper busbar. Then, lines are drawn on the V-shaped workpiece according to the measured dimensions. Finally, the cutting machine is used to cut the workpiece according to the drawn lines.

[0017] Furthermore, step S4 also includes a sub-step S41, which includes the following steps:

[0018] S410. Clamp the U-shaped copper busbar onto the wire cutting machine;

[0019] S411. Use measuring tools to align the U-shaped copper busbar;

[0020] S412. Select the electrode wire according to the U-shaped copper busbar and install the electrode wire on the wire cutting machine;

[0021] S413. Use wire EDM programming software to set the cutting process parameters according to the dimensions of the U-shaped copper busbar;

[0022] S414. Start the automatic processing mode of the wire cutting machine to cut the U-shaped copper busbar, so that a pair of symmetrical dovetail groove structures are formed on the inner side of the U-shaped opening of the U-shaped copper busbar.

[0023] Furthermore, in step S414, after processing the U-shaped copper busbar, the dimensions, shape, and precision of the processed U-shaped copper busbar are measured using measuring tools, and any cutting defects are checked to determine whether the processing requirements are met. Further, in step S9, the U-shaped copper busbar is clamped onto the wire cutting machine using a fixture, and the support assembly is placed inside the U-shaped opening of the U-shaped copper busbar, so that the two sides of the support assembly press against the inner walls of the two sides of the U-shaped opening.

[0024] Furthermore, the support assembly includes two opposing and spaced-apart support plates. Support screws are fixedly installed on the opposing surfaces of the two support plates. A connecting sleeve is provided at the opposing ends of the two support screws. The two ends of the connecting sleeve are threaded to the two support screws. Multiple fixing rods are evenly spaced on the outer side of the connecting sleeve, and the multiple fixing rods are perpendicular to the outer side wall of the connecting sleeve.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. In step S1, a forming mold with a V-shaped through groove is used to first extrude the hot copper billet into a V-shaped workpiece. At this stage, there is no need to set a mold core inside the mold; the forming of the V-shaped groove relies solely on the geometry of the mold cavity. This avoids the problem in existing U-shaped molds where the mold core is limited by the opening width, resulting in insufficient mechanical strength of the mold core. Simultaneously, in steps S2-S3, after the V-shaped workpiece cools, a mold core adapted to the U-shaped opening is placed inside the V-shaped groove, and pressure is applied to the V-shaped workpiece using a stamping press. At this time, the mold core acts as an external tool embedded in the V-shaped workpiece, and the V-shaped workpiece is subjected to impact pressure. The V-shaped workpiece bends under pressure, and due to the constraint of the mold core, it deforms into a U-shaped copper busbar. This allows the function of the mold core to shift to the stamping stage. Since the copper material has partially cooled and solidified at this point, the impact load during stamping is far lower than the dynamic impact during the extrusion stage. This improves the impact resistance of the forming mold, extends the service life of the forming mold and the mold core, and reduces the production cost of the U-shaped connector copper busbar.

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] Reference Figures 1 to 5 A connector copper busbar manufacturing process includes the following steps:

[0039] S1. The hot copper billet is pushed into the extruder, so that the hot copper billet passes through the preliminary forming components and is formed into a preliminary copper part;

[0040] S2. After the initial cooling of the copper parts, cut them to the predetermined length;

[0041] S3. The preliminary copper parts are formed into the target U-shaped copper busbar 1 using a forming device.

[0042] The hot copper billet is formed by heating it in a furnace. Specifically, workers select a suitable copper billet and place it in the furnace for heating, thus forming a hot copper billet. The preliminary forming component is a forming mold 2 with a V-shaped through groove 20. Cooling of the preliminary copper part is achieved through a water tank at the extruder outlet. The extruder pushes the preliminary copper part out of the outlet, causing it to fall into the water tank for cooling. The predetermined length is the length of the target U-shaped copper busbar 1. Workers cut the preliminary copper part according to the target U-shaped copper busbar 1. The forming device includes a mold core 3 and a stamping machine. The mold core 3 constrains the preliminary copper part, and the stamping machine then stamps it into the target U-shaped copper busbar 1.

[0043] In step S1, a forming mold 2 with a V-shaped through groove 20 is used to first extrude a hot copper billet into a V-shaped workpiece, which is the preliminary copper part. Because the forming mold 2 uses the V-shaped through groove 20 as the cavity for forming the V-shaped workpiece, the mold core of the forming mold 2 can be set larger than the mold core of the U-shaped mold in the prior art. At the same time, in steps S2 and S3, after the V-shaped workpiece cools down, the mold core 3 adapted to the U-shaped opening 10 is placed in the V-shaped groove, and pressure is applied to the V-shaped workpiece by a stamping machine. At this time, the mold core 3 acts as an external tool embedded in the V-shaped workpiece, and the V-shaped workpiece is subjected to impact pressure. The V-shaped workpiece bends after being subjected to pressure, and at the same time, due to the restriction of the mold core 3, the V-shaped workpiece bends and deforms into a U-shaped copper busbar 1.

[0044] Compared to the mold core of the U-shaped mold in the prior art, the mold core of the molding mold 2 in this embodiment has stronger impact resistance, which makes the service life of the molding mold 2 in this embodiment longer than that of the U-shaped mold in the prior art, thereby reducing the production cost of the copper busbar of the U-shaped connector.

[0045] In this embodiment, in step S1, the forming mold 2 with a V-shaped through groove 20 is used as a preliminary forming component, so that the hot copper blank passes through the forming mold 2 and is formed into a V-shaped workpiece.

[0046] Specifically, the forming mold 2 is a circular block with a V-shaped through groove in the center. The operator installs the forming mold 2 inside the extruder, aligning the hot copper billet with the V-shaped through groove 20. The hot copper billet is pushed through the V-shaped through groove 20 by the extruder to form a V-shaped workpiece. Because the forming mold 2 uses the V-shaped through groove 20 as the cavity for forming the V-shaped workpiece, the mold core of the forming mold 2 can be set larger than the mold core of the U-shaped mold in the prior art, resulting in a longer service life for the mold core of the forming mold 2 compared to the mold core of the U-shaped mold in the prior art.

[0047] In this embodiment, step S3 further includes sub-step S31, which includes the following steps:

[0048] S310, By placing a mold core 3 that matches the U-shaped opening 10 of the target U-shaped copper busbar 1 in the V-shaped groove of the V-shaped workpiece;

[0049] S311. The V-shaped workpiece with the die core 3 is stamped and deformed into a U-shaped copper busbar 1 by a stamping machine.

[0050] Specifically, the forming device includes a mold core 3 and a stamping machine. The mold core 3 is elongated and its dimensions are the same as those of the U-shaped opening 10. The stamping machine is existing technology and will not be described in detail here.

[0051] The operator places the mold core 3, which is adapted to the U-shaped opening 10, into the V-shaped groove of the V-shaped workpiece. Then, the V-shaped workpiece with the mold core 3 is placed on the stamping machine, with one side of the V-shaped workpiece facing the output end of the stamping machine. The stamping machine is then started to apply pressure to the V-shaped workpiece. At this time, the mold core 3 acts as an external tool embedded in the V-shaped workpiece. The V-shaped workpiece is subjected to impact pressure and bends under pressure. Simultaneously, due to the constraint of the mold core 3, the bending deformation forms a U-shaped copper busbar 1.

[0052] In this embodiment, step S4 is also included: using a wire cutting machine to cut a pair of symmetrically arranged dovetail grooves 11 on both sides inside the U-shaped opening 10 of the U-shaped copper busbar 1.

[0053] The wire cutting machine is existing technology and will not be discussed in detail here.

[0054] Step S4 creates a pair of symmetrically arranged dovetail grooves 11 inside the U-shaped opening 10 of the U-shaped copper busbar 1, enabling the U-shaped copper busbar 1 to cooperate with the connector, ensuring tight contact after insertion, reducing contact resistance, and enhancing conductivity.

[0055] Specifically, after the existing connector is inserted into the U-shaped copper busbar 1, both sides extend into the dovetail groove 11 and engage with the U-shaped copper busbar 1, thereby achieving tight contact, reducing contact resistance, and enhancing conductivity. Moreover, the connectors in the existing technology are all elastic, and the connector can be easily detached from the U-shaped copper busbar 1 by simply pressing.

[0056] In this embodiment, in step S2, the initial copper part is cut by a cutting machine. First, the dimensions are measured on the V-shaped workpiece according to the length of the U-shaped copper busbar 1. Then, lines are drawn on the V-shaped workpiece according to the measured dimensions. Finally, the cutting machine is used to cut the workpiece according to the drawn lines.

[0057] By measuring and marking, we ensure that the length of each U-shaped copper busbar 1 meets the design requirements, thus avoiding product defects caused by length deviations.

[0058] In this embodiment, step S4 further includes sub-step S41, which includes the following steps:

[0059] S410. Clamp the U-shaped copper busbar 1 onto the wire cutting machine;

[0060] S411. Use measuring tools to align the U-shaped copper busbar 1;

[0061] S412. Select an electrode wire according to the U-shaped copper busbar 1 and install the electrode wire on the wire cutting machine;

[0062] S413. Use wire EDM programming software to set the cutting process parameters according to the dimensions of the U-shaped copper busbar 1;

[0063] S414. Start the automatic processing mode of the wire cutting machine to cut the U-shaped copper busbar 1, so that a pair of symmetrical dovetail grooves 11 are formed on the inner side of the U-shaped opening 10 of the U-shaped copper busbar 1.

[0064] First, the U-shaped copper busbar 1 is clamped onto the wire EDM machine using a fixture. Then, a dial indicator is used to check if the U-shaped copper busbar 1 is aligned. Next, based on the cutting accuracy requirements of the U-shaped copper busbar 1, an electrode wire of matching diameter is selected and installed on the wire EDM machine. Then, using the wire EDM programming software, the part drawing is created according to the dimensions of the U-shaped copper busbar 1. The cutting process parameters are then set, and the wire EDM machine is operated for tool setting. Finally, the pre-programmed machining program is called, and the automatic machining mode of the wire EDM machine is started to cut the U-shaped copper busbar 1, so that a pair of symmetrical dovetail grooves 11 are formed on the inner side of the U-shaped opening 10 of the U-shaped copper busbar 1. After the cutting is completed, the machine is stopped and the processed U-shaped copper busbar 1 is removed.

[0065] Specifically, in existing technologies, if a dovetail groove 11 needs to be formed on a U-shaped copper busbar 1, a protruding structure adapted to the dovetail groove 11 needs to be set on the mold core 3. However, due to the small size of the dovetail groove 11, the mechanical strength of the mold core 3 with the protruding structure adapted to the dovetail groove 11 is extremely low, and it is prone to fatigue fracture during continuous extrusion. In this embodiment, the dovetail groove 11 is directly processed by wire cutting, eliminating the need for a complex mold structure and fundamentally eliminating the risk of mold core 3 fracture. Furthermore, the trapezoidal structure of the dovetail groove 11 (upper width 15.82mm, lower width 17.86mm, depth 0.76mm) requires extremely high dimensional accuracy. Wire cutting, through programming control of the electrode wire path, can achieve a processing accuracy of ±0.01mm, ensuring the symmetry and dimensional consistency of the dovetail groove 11 and avoiding errors caused by deformation or wear during mold extrusion.

[0066] In this embodiment, after the U-shaped copper busbar 1 is processed in step S414, the size, shape and accuracy of the processed U-shaped copper busbar 1 are measured with a measuring tool, and any cutting defects are checked to determine whether the processing requirements are met, so as to ensure that the size of the processed U-shaped copper busbar 1 meets the processing requirements.

[0067] Although the wire EDM machine in step S4 can ensure the symmetry and dimensional consistency of the dovetail groove 11 and avoid errors caused by deformation or wear during mold extrusion molding, the following situation may occur when using the clamps on the wire EDM machine to hold the U-shaped copper busbar 1: that is, when the operator clamps the two sides of the U-shaped copper busbar 1 with the clamps, the force is not well controlled, resulting in excessive force on the clamps, causing the two ends of the U-shaped copper busbar 1 to be concave inward toward the U-shaped opening 10, resulting in dimensional errors in the U-shaped opening 10. To solve this technical problem, in step S4 of this embodiment, before clamping the U-shaped copper busbar 1 onto the wire EDM machine with the clamps, the support component 6 is placed inside the U-shaped opening 10 of the U-shaped copper busbar 1, so that the two sides of the support component 6 respectively press against the inner walls of the two sides of the U-shaped opening 10, referring to... Figure 6 The support assembly 6 includes two opposing and spaced-apart support plates 60. Support screws 61 are fixedly installed on the opposing surfaces of the two support plates 60. A connecting sleeve 62 is provided at the opposing ends of the two support screws 61. The two ends of the connecting sleeve 62 are threaded to the two support screws 61. Multiple fixing rods 63 are evenly spaced on the outer side of the connecting sleeve 62. The multiple fixing rods 63 are all perpendicular to the outer side wall of the connecting sleeve 62.

[0068] By setting the support component 6, the U-shaped copper busbar 1 is clamped onto the wire cutting machine using a clamp. First, the connecting sleeve 62 is rotated clockwise, causing the two support screws 61 to drive the support plates 60 towards the connecting sleeve 62, so that the distance between the two support plates 60 is less than the U-shaped opening 10 of the U-shaped copper busbar 1. At this time, the support component 6 can be placed inside the U-shaped opening 10, with the two support plates 60 facing the two sides of the U-shaped opening 10 respectively. Then, the connecting sleeve 62 is rotated counterclockwise, causing the two support screws 61 to drive the support plates 60 towards the two sides of the U-shaped opening 10. The support plate 60 moves away from the connecting sleeve 62, so that the two support plates 60 abut against the two sides of the U-shaped opening 10, providing support for the two sides of the U-shaped opening 10. In this way, when the operator clamps the two sides of the U-shaped copper busbar 1 with the clamp, if the force is not controlled properly, the U-shaped copper busbar 1 will not be concave because of the support of the support plate 60, thus ensuring the dimensional accuracy of the U-shaped copper busbar 1 during processing. In addition, the fixing rod 63 perpendicular to the outer wall of the connecting sleeve 62 makes it more convenient for the operator to rotate the connecting sleeve 62.

[0069] Example 2

[0070] The difference between this embodiment and Embodiment 1 is that in step S1, the molding mold 4 with a large U-shaped through groove 40 (refer to...) Figure 7 As a preliminary forming component, the hot copper billet is formed into a U-shaped workpiece by the forming mold 4. The overall size of the U-shaped workpiece is larger than the size of the target U-shaped copper busbar 1.

[0071] Specifically, the molding mold 4 is composed of a circular block with a large U-shaped through groove 40. The overall size of the large U-shaped through groove 40 is larger than the size of the target U-shaped copper busbar 1. In other words, the thickness of the mold core inside the large U-shaped through groove 40 of the molding mold 4 is greater than the width of the U-shaped opening 10 of the target U-shaped copper busbar 1.

[0072] A forming mold 4 with a large U-shaped through groove 40 is used, and this forming mold 4 is installed in a first extruder. The hot copper billet is pushed by the first extruder through the large U-shaped through groove 40 and then through the forming mold 4 to form a U-shaped workpiece, which is the preliminary copper part. Because the core thickness of the forming mold 4 is significantly greater than the width of the target U-shaped opening 10 (e.g., designed to be 8-10 mm), by reserving a larger opening width (e.g., 6-7 mm), the core of the forming mold 4 is larger than the core of existing U-shaped molds, resulting in a mechanical strength 3-5 times greater and a lower risk of fracture under impact loads compared to existing U-shaped molds.

[0073] The difference between this embodiment and Embodiment 1 is that step S3 further includes a sub-step S31, which includes the following steps:

[0074] S310. Heating the U-shaped workpiece transforms it into a plastic, hot U-shaped workpiece.

[0075] S311. Push the U-shaped workpiece into the second extruder, so that the U-shaped workpiece passes through the production mold 5 with a forming U-groove 50 of the same size as the target U-shaped copper busbar 1 (refer to...). Figure 8 ), and formed into the target U-shaped copper busbar 1.

[0076] After reheating the rough-formed U-shaped workpiece (opening width > 5.31 mm), the opening width is precisely adjusted to the size of the target U-shaped copper busbar 1 through the forming U-groove 50 of the production mold 5.

[0077] Specifically, the U-shaped workpiece is heated in a furnace, at which point it is in a hot, plastic state with low deformation resistance and significantly reduced extrusion pressure. The extruder then pushes the hot U-shaped workpiece through the forming U-groove 50 and into the production mold 5. The production mold 5 only needs to complete dimensional corrections and does not need to bear the high load of rough forming. Therefore, the core thickness of the production mold 5 can remain consistent with the target opening width (5.31mm), but the actual stress is significantly reduced compared to the core of existing U-shaped molds, eliminating the risk of fatigue fracture. This results in a longer service life for the forming mold 4 and the production mold 5 compared to existing U-shaped molds, thereby reducing the production cost of the U-shaped connector copper busbar.

[0078] However, compared to Embodiment 1, this embodiment requires two extruders and a heating furnace (to facilitate the transfer of heated workpieces, extruders and heating furnaces are usually set up together, with the heating furnace located on one side of the extruder's feed inlet; after heating, the heated workpiece can be directly transferred to the matching extruder), resulting in a larger equipment investment. Embodiment 1 only requires one extruder and one stamping press, requiring less equipment investment. However, in this embodiment, the plastic mold 4 and the production mold 5 have a clear division of labor, resulting in less downtime and higher overall production efficiency compared to Embodiment 1.

[0079] Therefore, Example 1 is suitable for production scenarios with small production scale and limited budget, while this example is suitable for production scenarios with large production scale and sufficient equipment investment.

[0080] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
