Abstract
Description
Technical Field
[0001] This invention relates to the field of copper busbar processing technology, specifically to an integrated copper busbar processing equipment. Background Technology
[0002] With the rapid development of industries such as power equipment, new energy vehicles, and data centers, the demand for copper busbars as key conductive connectors is increasing. Their shape complexity, precision requirements, and production batch diversity are also increasing significantly. Intelligent manufacturing technology provides systematic solutions to these challenges through automation, digitalization, and flexibility.
[0003] As a key conductive connection component in power transmission and distribution systems, the shape and dimensional accuracy of copper busbars directly affect the assembly efficiency, contact reliability, and long-term operational safety and stability of electrical equipment. They often need to be processed into precision components with features such as bends and irregular holes. Among these, copper busbars with "U"-shaped or similar complex bending structures are widely used. Their processing quality, especially the symmetry accuracy of the two sides after bending, is crucial to ensuring accurate matching with interfaces of equipment such as circuit breakers and disconnect switches. However, the following problems still exist: 1. For "U" shaped bends that require symmetrical indentation towards the center from both sides, traditional bending machines cannot ensure that the material at both ends shrinks completely synchronously and equally during the plastic flow process, resulting in inconsistent bending angles and straight segment lengths on both sides, forming asymmetrical skewed workpieces. 2. In the existing technology, the processing of such copper busbars usually adopts the method of drilling holes first and then bending. Since the bending process will cause the material to undergo large plastic deformation and displacement, and complex stress changes will occur with the overall deformation, the pre-processed round holes are often pulled into elliptical, polygonal or irregular shapes, and burrs or micro-cracks will be generated on the edge of the holes, which will affect the smooth insertion of the connecting bolts and further weaken the effective cross-sectional area and mechanical strength of the conductor. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides an integrated processing equipment for copper busbars. The main solution is to address the limitations of traditional bending machines in ensuring that the material at both ends contracts synchronously and equally during plastic flow, leading to inconsistent bending angles and straight section lengths on both sides, resulting in asymmetrical and skewed workpieces. Furthermore, the method of pre-drilling holes before bending causes significant plastic deformation and displacement of the material during the bending process, resulting in complex stress changes along with the overall deformation. This often causes pre-processed circular holes to be pulled into elliptical, polygonal, or irregular shapes, producing burrs or micro-cracks on the hole edges, affecting the smooth insertion of connecting bolts, and further weakening the effective cross-sectional area and mechanical strength of the conductor.
[0005] To achieve the above objectives, the present invention provides the following technical solution: An integrated processing equipment for copper busbars includes a support base, a top bracket mounted on the upper surface of the support base, a central stamping assembly for stamping the middle section of the copper busbar slidably mounted on the top bracket, a central punching assembly for punching the center part of the copper busbar installed inside the central stamping assembly, a hydraulic cylinder mounted on the upper surface of the top bracket for moving the central stamping assembly up and down along the top bracket, an edge pushing assembly for pushing the two vertical edges of the initially stamped copper busbar slanted inside the central stamping assembly, and edge pressing and opening assemblies mounted at both ends of the central stamping assembly for stamping the two edges of the pushed-slanted copper busbar. The upper surface of the support base has a mold groove, in which a sliding support plate for supporting the copper busbar is slidably connected, cooperating with the central stamping assembly to achieve initial shaping. A locking and positioning assembly for locking the initial position of the sliding support plate is provided on one side of the support base.
[0006] Furthermore, the middle stamping assembly includes a sliding table slidably connected between two vertical sections of the top support. The bottom of the sliding table is fixedly connected to a middle section forming mold frame, and there is a gap between the sliding table and the middle section forming mold frame, with reinforcing ribs welded into the gap for support.
[0007] Based on the aforementioned scheme, the pushing edge assembly includes two partitions symmetrically connected to the inner cavity of the middle section forming mold frame. Between the inner walls on both sides of the inner cavity of the middle section forming mold frame and near the ends of the two openings, there is a rotating push plate that rotates along the axis of the bearing seat via a bearing seat. The back of the rotating push plate is rotatably connected to the partitions via a mounting seat, and a cylinder is used to rotate and push the rotating push plate to tilt the two vertical edges of the initially formed copper busbar. The opposite sides of the two rotating push plates are provided with multiple strip grooves along the length direction.
[0008] As a further embodiment of the present invention, a bottom support plate with a width greater than that of the sliding support plate is fixedly connected to the lower surface of the sliding support plate, and a plurality of cylinders I are fixedly connected to the lower surface of the bottom support plate. A plurality of cylinders II, corresponding to and cooperating with the cylinders I, are fixedly connected to the bottom inner wall of the support base. A plurality of springs are welded between the lower surface of the bottom support plate and the bottom inner wall of the support base for resetting the sliding support plate.
[0009] Furthermore, the central punching assembly includes a cylinder one fixedly connected to the center position of the top of the middle section forming die frame. The telescopic end of the cylinder one is fixed to the punching head by bolts. The bottom of the middle section forming die frame is provided with a clearance hole one for the punching head to pass through and punch the center part of the copper busbar. The center position of the upper surface of the sliding support plate is provided with a clearance hole two that cooperates with the clearance hole one to avoid the punching head.
[0010] Based on the aforementioned scheme, the edge pressing and opening assembly includes side connecting frames fixedly connected to both sides of the sliding table. A hydraulic cylinder is fixedly connected to the upper surface of the side connecting frame. A square bracket is fixedly connected to the telescopic end of the hydraulic cylinder through the side connecting frame. Guide rails are fixedly connected to both inner walls of the square bracket. A slide is slidably connected between the two guide rails. A fixing frame is fixedly connected to the upper surface of the slide. A drive motor is fixedly connected to the top of the fixing frame. A drill bit is installed at the output end of the drive motor through a coupling. A side pressing block is fixedly connected to the lower surface of the square bracket to flatten the two vertical edges of the copper busbar that has been pushed. A cylinder is fixedly connected between the slide and the top inner wall of the square bracket to move the slide up and down along the guide rail. A through round hole is opened on both the square bracket and the side pressing block for the drill bit to pass through. A round hole is opened on the top outer wall of the support base to avoid the drill bit.
[0011] As a further embodiment of the present invention, sliding connecting seats are fixedly connected to both outer walls of the square bracket, and guide rods are slidably connected through and in each sliding connecting seat. The two ends of the guide rods are respectively fixed to the top outer wall of the support base and the top inner wall of the top bracket.
[0012] Furthermore, the locking and positioning assembly includes two locking holes on one side of the sliding plate, and a U-shaped bracket that mates with the two locking holes is inserted through and slidably connected to one side of the support base. A clearance groove is provided on one side of the support base, and a cylinder four that causes the U-shaped bracket to insert into or disengage from the locking holes is fixedly connected in the clearance groove.
[0013] Based on the aforementioned scheme, the upper surface of the sliding plate is fixedly connected with a plurality of side positioning strips that respectively position the two wide sides of the copper busbar, and the upper surface of the support base is fixedly connected with end positioning strips that define the positions of the two ends of the copper busbar.
[0014] As a further embodiment of the present invention, multiple springs are respectively sleeved on the outer sides of corresponding cylinder one and cylinder two, and the upper surface of the sliding plate when fully reset is flush with the top outer wall of the support base. At this time, the distance between cylinder one and cylinder two is equal to the thickness of the copper busbar.
[0015] Compared with the prior art, the present invention provides an integrated processing equipment for copper busbars, which has the following beneficial effects: 1. The present invention provides a central positioning hole for the copper busbar, and after punching the central hole, the punching head is used as a positioning pin. During subsequent U-shaped stamping, the two ends of the copper busbar are forced to synchronously and symmetrically retract towards the center, ensuring the symmetry accuracy of the formed part.
[0016] 2. This invention adopts a process of pressing and shaping the shape before drilling, which avoids the drastic change in internal stress of the copper busbar caused by drilling first and then bending, which can lead to quality defects such as twisting, elongation or misalignment of the processed holes. By completing the plastic deformation of all shapes first, and then drilling precisely in a shaped and stress-stable state, the accuracy of the shape and size of the final holes is ensured.
[0017] 3. In this invention, the workpiece is pressed during the stamping, tilting, and drilling processes, which effectively avoids processing deviations caused by workpiece loosening or displacement, ensures the accuracy and consistency of the processing position in each process, and further improves the overall processing quality of the copper busbar.
[0018] 4. This invention integrates multiple key processes required for copper busbar processing, such as U-shaped stamping, flattening, and drilling, into one machine and completes them sequentially through an automated program. Compared with the step-by-step processing mode of multiple machines, it achieves one-time clamping, fully automatic, and continuous completion, which greatly shortens the turnaround, positioning, and auxiliary time between processes and greatly improves production efficiency.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0024] Please see Figures 1-10 As shown, an integrated processing equipment for copper busbars includes a support base 1. A top bracket 2 is bolted to the upper surface of the support base 1. A middle punching assembly 4 for stamping the middle section of the copper busbar is slidably mounted on the top bracket 2. A center punching assembly 6 for punching the center part of the copper busbar is installed inside the middle punching assembly 4. A hydraulic cylinder 3 for moving the middle punching assembly 4 up and down along the top bracket 2 is bolted to the upper surface of the top bracket 2. A center punching assembly 6 for punching the center part of the copper busbar is installed inside the middle punching assembly 4. The two vertical edges of the initially stamped copper busbar are pushed by the push-edge assembly 7. Both ends of the middle stamping assembly 4 are equipped with edge pressing and opening assemblies 8, which are used to stamp and form the two edges of the pushed copper busbar. The upper surface of the support base 1 is provided with a mold groove 5, which cooperates with the middle stamping assembly 4 to achieve preliminary shaping. A sliding support plate 501 for supporting the copper busbar is slidably connected in the mold groove 5. A locking and positioning assembly 9 for locking the initial position of the sliding support plate 501 is provided on one side of the support base 1.
[0025] First, the copper busbar to be processed is placed on the support base 1. Then, the central punching assembly 4 is activated and pressed down (at this time, the sliding support plate 501 is locked) until it contacts the copper busbar. Then, the center punching assembly 6 punches a hole in the center of the copper busbar. After punching, the center punching assembly 6 does not reset and is used for positioning to ensure that both ends of the copper busbar retract simultaneously during the subsequent preliminary punching process. Then, the locking of the sliding support plate 501 is released, and the central punching assembly 4 moves down to perform preliminary punching of the copper busbar. After the preliminary punching is completed, the central punching assembly 4 remains stationary. The copper busbar is moved (always in a pressed state). The two vertical sections of the copper busbar are pushed at an angle by the pushing edge assembly 7 (to facilitate subsequent edge flattening). After the angle is pushed, the edge is flattened by the edge pressing and hole-making assembly 8 (the pressed state is maintained after flattening without resetting). After flattening, holes are drilled at the two edge positions. After all is completed, the pushing edge assembly 7 is reset, then the middle punching assembly 4 is reset, and the sliding support plate 501 is reset while pushing out the processed copper busbar for easy removal. After the reset is completed, the sliding support plate 501 is locked again, thus completing the processing.
[0026] It should be noted that: hydraulic cylinder 3 is an actuator in the hydraulic system. It achieves the telescopic function by cooperating with the hydraulic system. It can also achieve precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with magnetic switches, proximity switches or photoelectric switches. Those skilled in the art can set it according to actual needs, which will not be elaborated here.
[0027] A center positioning hole is made in the copper busbar, and after the center hole is punched, the punch head 602 is also used as a positioning pin. During the subsequent U-shaped stamping, the two ends of the copper busbar are forced to shrink symmetrically towards the center at the same time, which ensures the symmetry accuracy of the formed part.
[0028] By employing a process of pressing and shaping the shape before drilling, the drastic changes in internal stress of the copper busbar caused by drilling first and then bending can be avoided, which can lead to quality defects such as twisting, elongation, or misalignment of the processed holes. By completing the plastic deformation of all shapes first and then precisely drilling the holes in a shaped and stress-stable state, the accuracy of the final hole shape and size is ensured.
[0029] like Figures 2-3 As shown, in order to perform preliminary stamping of copper busbars, the middle stamping component 4 in this invention includes a sliding table 401 slidably connected between two vertical sections of the top support 2. The bottom of the sliding table 401 is fixedly connected to the middle section forming mold frame 402 by bolts, and there is a gap between the sliding table 401 and the middle section forming mold frame 402, and reinforcing ribs are welded in the gap for support.
[0030] Before processing, the initial position of the sliding tray 501 is locked by the locking and positioning component 9, and the copper busbar to be processed is placed. Then, the hydraulic cylinder 3 is started to drive the sliding table 401 and the middle section forming mold frame 402 to press down as a whole, pressing the copper busbar onto the locked sliding tray 501.
[0031] like Figure 4 As shown, to ensure that both ends retract towards the center synchronously during the punching process of the copper busbar, the present invention employs a center punching assembly 6, which includes a cylinder 601 fixedly connected to the center of the top of the middle forming die frame 402 by bolts. The telescopic end of the cylinder 601 is fixed to the punching head 602 by bolts. The bottom of the middle forming die frame 402 is provided with a first clearance hole 603 for the punching head 602 to pass through and punch the center of the copper busbar. The center of the upper surface of the sliding support plate 501 is provided with a second clearance hole 604, which cooperates with the first clearance hole 603 to avoid the punching head 602.
[0032] After the copper busbar is initially pressed by the middle punching assembly 4, the cylinder 601 is activated to push the punching head 602 downward, passing through the first clearance hole 603 of the middle pressing die frame 402 and the second clearance hole 604 of the sliding support plate 501, punching out the first hole at the center of the copper busbar. After punching is completed, the cylinder 601 does not retract and reset, and the punching head 602 remains in the extended state, staying in the hole that was just punched. At this time, the punching head 602 acts as a center positioning pin to ensure that the two ends of the copper busbar can synchronously and symmetrically retract inward from this center point in subsequent steps.
[0033] like Figures 6-7 As shown, in this invention, a bottom support plate 502 with a width greater than that of the sliding support plate 501 is fixedly connected to the lower surface of the sliding support plate 501 by bolts. A plurality of cylinders 503 are fixedly connected to the lower surface of the bottom support plate 502 by bolts. A plurality of cylinders 504 corresponding to and cooperating with the cylinders 503 are fixedly connected to the bottom inner wall of the support base 1 by bolts. A plurality of springs 505 are welded between the lower surface of the bottom support plate 502 and the bottom inner wall of the support base 1 for resetting the bottom sliding support plate 501.
[0034] Further, multiple springs 505 are respectively sleeved on the outer side of the corresponding cylinder 1 503 and cylinder 2 504, and the upper surface of the sliding plate 501 when fully reset is flush with the top outer wall of the support base 1. At this time, the distance between cylinder 1 503 and cylinder 2 504 is equal to the thickness of the copper busbar.
[0035] Specifically, after the first hole is machined, the locking and positioning assembly 9 releases the lock on the sliding support plate 501. With the punch head 602 in place, the hydraulic cylinder 3 continues to drive the middle punching assembly 4 to press down. During the pressing, the middle forming die frame 402 presses the copper busbar into the die groove 5, forcing both ends of the copper busbar to retract towards the center from the center positioning point, thus initially punching the copper busbar into a U-shape until cylinder one 503 and cylinder two 504 contact. During this process, the sliding support plate 501 moves down synchronously under pressure, and the spring 505 at its bottom is compressed and stores energy. After the initial punching is completed, the hydraulic cylinder 3 maintains pressure, so that the middle forming die frame 402 continues to press the copper busbar, providing stable support for subsequent processes.
[0036] To facilitate locking the position of the sliding plate 501 after reset, the present invention employs a locking and positioning assembly 9, which includes two locking holes 901 on one side of the sliding plate 501. A U-shaped insert 902 that mates with the two locking holes 901 is inserted through and slidably connected to one side of the support base 1. A clearance groove 903 is provided on one side of the support base 1. A cylinder 904 that causes the U-shaped insert 902 to insert into or disengage from the locking holes 901 is fixedly connected to the clearance groove 903 by bolts. By retracting or extending the cylinder 904, the U-shaped insert 902 is pulled or pushed into or disengaged from the locking holes 901 on the side of the sliding plate 501, thereby locking or releasing the sliding plate 501.
[0037] like Figure 4 As shown, after the initial stamping of the copper busbar, the copper busbar is U-shaped, which does not meet the requirements of subsequent processing. In this invention, the pushing edge assembly 7 includes two partition plates 701 that are symmetrically connected to the inner cavity of the middle section forming mold frame 402 by bolts. Between the inner walls on both sides of the inner cavity of the middle section forming mold frame 402 and near the ends of the two openings, there is a rotating push plate 702 that rotates along the axis of the bearing seat through a bearing seat. The back of the rotating push plate 702 and the partition plate 701 are rotatably connected to a cylinder 703 through a mounting seat, which is used to rotate the rotating push plate 702 to push the two vertical edges of the initially stamped copper busbar. The opposite sides of the two rotating push plates 702 are provided with multiple strip grooves 704 along the length direction.
[0038] Specifically, after the initial stamping of the copper busbar, the pushing assembly 7 starts to work. The cylinder 703 extends and pushes the rotating push plate 702 to rotate inward around the bearing seat axis. The rotating push plate 702 contacts and pushes the two vertical edges of the U-shaped copper busbar, causing the upper part of the copper busbar to be pushed outward at an angle greater than 45°, creating space and conditions for the next edge flattening process. After the pushing is completed, the rotating push plate 702 is reset and fully retracted into the middle section forming mold frame 402.
[0039] After the two sides of the copper busbar are tilted, the edge pressing and opening components 8 on both sides simultaneously flatten and open the tilted edges, such as... Figure 5 As shown, the edge pressing and opening assembly 8 in this invention includes side connecting frames 801 that are fixedly connected to both sides of the sliding table 401 by bolts. A hydraulic cylinder 814 is fixedly connected to the upper surface of the side connecting frame 801 by bolts. A square bracket 802 is fixedly connected to the telescopic end of the hydraulic cylinder 814 through the side connecting frame 801 by bolts. A side pressing block 813 is fixedly connected to the lower surface of the square bracket 802 by bolts to flatten the two vertical edges of the copper busbar that has been pushed. Specifically, when the hydraulic cylinder 814 is activated, it drives the square bracket 802 and the side pressing block 813 at its bottom to move steadily downward along the guide rod 811. The side pressing block 813 flattens the edges of the copper busbar that have been pushed.
[0040] It should be noted that the hydraulic cylinder 814 is an actuator in the hydraulic system. It achieves the telescopic function by cooperating with the hydraulic system. Furthermore, by cooperating with a magnetic switch, proximity switch, or photoelectric switch, it achieves precise control of the telescopic displacement of the hydraulic cylinder piston rod. Those skilled in the art can set it according to actual needs, which will not be elaborated here.
[0041] The inner walls of both sides of the square bracket 802 are fixedly connected to guide rails 803 by bolts. A slide table 804 is slidably connected between the two guide rails 803. A fixing frame 806 is fixedly connected to the upper surface of the slide table 804 by bolts. A drive motor 807 is fixedly connected to the top of the fixing frame 806 by bolts. A drill bit 808 is installed at the output end of the drive motor 807 through a coupling. A cylinder 805 is fixedly connected between the slide table 804 and the top inner wall of the square bracket 802 by bolts, which is used to move the slide table 804 up and down along the guide rails 803. A through round hole 809 is opened on both the square bracket 802 and the side pressure block 813 for the drill bit 808 to pass through. A round hole 810 is opened on the top outer wall of the support base 1 to avoid the drill bit 808.
[0042] It should be noted that the drive motor 807 is a servo motor with an encoder. The number of rotations and the rotation angle of the motor output shaft are controllable and highly accurate. Those skilled in the art can set it according to actual needs, which will not be elaborated here.
[0043] Specifically, after the edge is flattened, the hydraulic cylinder 814 remains stationary, and the starting cylinder 805 drives the slide table 804 and the drive motor 807 and drill bit 808 to move down along the guide rail 803. The drive motor 807 starts and drives the drill bit 808 to rotate at high speed. The drill bit 808 passes through the square bracket 802 and the first round hole 809 on the side pressing block 813 in sequence, drilling the required hole on the edge of the copper busbar that has been flattened. The depth of the hole is avoided by the second round hole 810 on the support base 1. After the hole is drilled, the cylinder 805 drives the drill bit 808 to retract, but the hydraulic cylinder 814 maintains pressure, and the side pressing block 813 continues to press the edge of the workpiece for shaping.
[0044] Since the square bracket 802 is only connected by the oil cylinder 814, it is prone to tilting during the up and down movement. In this invention, the outer walls of both sides of the square bracket 802 are fixedly connected to the sliding connecting seats 812 by bolts. Guide rods 811 are inserted and slidably connected in the sliding connecting seats 812. The two ends of the guide rods 811 are fixed to the top outer wall of the support base 1 and the top inner wall of the top bracket 2, respectively.
[0045] like Figure 6As shown, in order to facilitate the initial positioning of the copper busbar, the upper surface of the sliding support plate 501 is fixedly connected with multiple side positioning strips 11 that respectively position the two wide sides of the copper busbar, and the upper surface of the support base 1 is fixedly connected with end positioning strips 10 that define the positions of the two ends of the copper busbar, by bolts.
[0046] Before processing, the copper busbar to be processed is placed on the upper surface of the sliding tray 501. The two wide sides of the copper busbar are limited by the side positioning strips 11, and its ends abut against the end positioning strips 10 to achieve fast and accurate initial positioning.
[0047] After all processing steps are completed, the hydraulic cylinder 814 retracts, causing the entire flattening and punching component to move upward and reset. Subsequently, the pneumatic cylinder 601 retracts, and the punch head 602 is pulled out of the workpiece. The hydraulic cylinder 3 retracts and drives the central punching assembly 4 to move upward and reset. During the reset process of the central punching assembly 4, the compressed spring 505 under the sliding support plate 501 releases its stored energy, pushing the sliding support plate 501 upward and restoring it to be flush with the top surface of the support base 1. At the same time, the processed copper busbar is pushed out of the mold groove 5 for easy removal by the operator. The pneumatic cylinder 904 retracts, pulling the U-shaped insert 902 into the locking hole 901 of the sliding support plate 501, preparing for the next processing cycle.
[0048] It should be noted that the cylinders used are all power actuators that convert the pressure energy of compressed air into mechanical energy. By controlling the gas in and out, the piston is driven to perform linear reciprocating motion. The cylinder piston rod extension and retraction displacement can be precisely controlled by cooperating with magnetic switches, proximity switches or photoelectric switches. Those skilled in the art can set it according to actual needs, which will not be elaborated here.
[0049] The present invention is used in the following steps: S1: First, place the copper busbar to be processed on the upper surface of the sliding tray 501. The two wide sides of the busbar are limited by the side positioning strip 11, and its end abuts against the end positioning strip 10 to achieve fast and accurate initial positioning. The cylinder 904 in the locking positioning assembly 9 retracts and pulls the U-shaped bracket 902 into the locking hole 901 on the side of the sliding tray 501, so as to firmly lock the sliding tray at the initial height position. S2: After the copper busbar is installed, the hydraulic cylinder 3 is activated to drive the sliding table 401 and the middle section forming mold frame 402 to press down as a whole, pressing the copper busbar onto the locked sliding support plate 501. Then, the cylinder 601 is activated to push the punch head 602 downward, passing through the first clearance hole 603 of the middle section forming mold frame 402 and the second clearance hole 604 of the sliding support plate 501, punching out the first hole at the center of the copper busbar. After punching, the cylinder 601 does not retract and reset, and the punch head 602 remains in the extended state, remaining in the hole that was just punched. At this time, the punch head 602 acts as a center positioning pin to ensure that the two ends of the copper busbar can synchronously and symmetrically retract inward from this center point in subsequent steps. S3: After the first hole is processed, the lock on the sliding support plate 501 is released, and the cylinder 4 904 is activated to extend, pushing the U-shaped insert 902 out of the locking hole 901, thereby releasing the lock on the sliding support plate 501. With the punch head 602 in place, the hydraulic cylinder 3 continues to drive the middle punching component 4 to press down. When pressing down, the middle pressing mold frame 402 presses the copper busbar into the mold groove 5, forcing both ends of the copper busbar to retract towards the center at the center positioning point, thereby initially punching the copper busbar into a U-shape until cylinder 1 503 and cylinder 2 504 contact. During this process, the sliding support plate 501 moves down synchronously under pressure, and the spring 505 at its bottom is compressed and stores energy. After the initial punching is completed, the hydraulic cylinder 3 maintains the pressure, so that the middle pressing mold frame 402 continues to press the copper busbar, providing stable support for subsequent processes. S4: After the initial stamping of the copper busbar, the pusher assembly 7 starts to work. The cylinder 2 703 extends and pushes the rotating pusher plate 702 to rotate inward around the bearing seat axis. The rotating pusher plate 702 contacts and pushes the two vertical edges of the U-shaped copper busbar, so that the upper part of the copper busbar is pushed outward at an angle greater than 45°, creating space and conditions for the next edge flattening process. After the pushing is completed, the rotating pusher plate 702 is reset and fully retracted into the middle section forming mold frame 402. S5: After the two sides of the copper busbar are tilted, the edge pressing and hole-opening components 8 on both sides simultaneously act to flatten and open the tilted edges. First, the hydraulic cylinder 814 starts to drive the square bracket 802 and the side pressing block 813 at its bottom to move steadily down along the guide rod 811. The side pressing block 813 flattens the previously tilted edges of the copper busbar. After the edges are flattened, the hydraulic cylinder 814 remains stationary, and the pneumatic cylinder 805 starts to drive the slide table 804 and the drive motor 807 and drill bit 808 on it. Moving down along the guide rail 803, the drive motor 807 starts and drives the drill bit 808 to rotate at high speed. The drill bit 808 passes through the first round hole 809 on the square bracket 802 and the side pressure block 813 in sequence, drilling the required hole on the edge of the copper busbar that has been flattened. The depth of the drilling is avoided by the second round hole 810 on the support base 1. After the drilling is completed, the cylinder 805 drives the drill bit 808 to retract, but the oil cylinder 814 maintains pressure, and the side pressure block 813 continues to press the edge of the workpiece for shaping. S6: After all processing steps are completed, the hydraulic cylinder 814 retracts to move the entire flattening and opening component upwards and resets. Then, the pneumatic cylinder 601 retracts and the punch head 602 is pulled out of the workpiece. The hydraulic cylinder 3 retracts and drives the central punching assembly 4 to move upwards and reset. During the reset process of the central punching assembly 4, the compressed spring 505 under the sliding support plate 501 releases its stored energy, pushing the sliding support plate 501 upwards to restore it to the same level as the top surface of the support base 1. At the same time, the processed copper busbar is pushed out of the mold groove 5 for easy removal by the operator. The pneumatic cylinder 904 retracts and pulls the U-shaped insert 902 into the locking hole 901 of the sliding support plate 501, preparing for the next processing cycle.
