Description

Technical Field

[0001] The present invention relates to the technical field of copper busbar bending, and in particular to a copper busbar bending device for new energy vehicles. Background Art

[0002] A soft copper busbar is a special conductive connector made of high-purity copper. Its core characteristics lie in its exceptional flexibility and bendability, which distinguish it from traditional rigid copper busbars. To adapt to the complex and compact interior layout requirements of new energy vehicles, soft copper busbars must undergo precise bending and forming during production, tailored to the electrical design and physical installation space of the specific vehicle model. This carefully bent soft copper busbar acts like a tailor-made flexible bridge, navigating flexibly and precisely within the limited interior space of the vehicle, securely connecting the motor and power supply, and thus carrying the high current required for vehicle operation. Therefore, the soft copper busbar and its precise bending process are key foundational components that ensure the smooth and reliable transmission of electrical energy within the powertrain of new energy vehicles, and can be described as the flexible lifeblood of the vehicle's energy flow.

[0003] At present, in the conventional process of bending soft copper busbars, the commonly used operation method is to use a bending machine. In actual use, the operator first needs to use the clamp equipped with the bending machine to firmly clamp the side of the copper busbar that needs to be kept stable, and then start the equipment to drive the bending die or mechanism to apply bending force to the free end of the other side of the copper busbar that is not clamped, so as to complete the required bending forming. Different soft copper busbars often have different thickness specifications. When these copper busbars of different thicknesses need to be bent in sequence, the operators have to frequently interrupt the continuous operation process. In order to adapt to the specific thickness of each new copper busbar, they must manually adjust the pressure on the bending machine. The fastening bolts on the relevant fixture components, positioning tooling or other limiting devices above, these adjustment actions include loosening the bolts, moving the fixture or tooling position to match the thickness of the copper busbar, and then re-tightening the bolts to fix it. This series of repetitive manual operations for tightening, adjusting the position and re-locking the bolts is essentially to achieve effective clamping and limiting of copper busbars of different thicknesses. However, this inherent method of mechanical adjustment makes the entire bending preparation process multi-step, time-consuming and physically demanding, which invisibly increases the complexity of the operation and the labor intensity of the workers, and ultimately inevitably slows down the overall operation rhythm of the copper busbar bending process and reduces the efficiency of the copper busbar bending. Summary of the Invention

[0004] The object of the present invention is to provide a copper busbar bending device for new energy vehicles to solve the problem proposed in the above background technology that in the process of bending a soft copper busbar, one side of the copper busbar is often fixed by a bending machine, and then the unclamped side of the copper busbar is bent by the bending machine. However, due to the difference in thickness between the copper buses, when bending different copper buses, it is necessary to adjust the bolts of the upper clamps, tooling and other equipment of the bending machine to limit the copper buses of different thicknesses, which makes the operation of bending the copper busbar more complicated and reduces the efficiency of bending the copper busbar.

Sliding grooves are provided on the left and right sides of the front side of the support seat, and two bending rods are slidingly provided inside the sliding groove. The side surfaces of the bending rods are respectively matched with the inside of the oblique groove and the transverse groove.

[0007] Preferably, stretching grooves are provided on the front and back sides of the top surface of the square frame, and L-shaped blocks are slidably provided on the side surfaces of the inner walls of the stretching grooves. Limiting plates are fixedly provided on the tops of the two vertical blocks of the two L-shaped blocks, and three slots are provided on the front sides of the vertical blocks of the front L-shaped blocks. The stretching grooves provide a vertical sliding path for the L-shaped blocks, so that they can drive the limiting plates to rise and fall.

[0008] Preferably, a through slot is provided in the middle of the inner wall of the square frame, a fixed frame is slidably provided inside the through slot, five rectangular slots are provided in a straight line at equal distances on the front side of the fixed frame, and the left side of the inner wall of the fixed frame extends to the outside of the square frame. The through slot allows the fixed frame to slide horizontally so that it can compress or release the copper busbar. The design of multiple rectangular slots facilitates the selection of the locking position according to the thickness of the copper busbar, and the extended part of the fixed frame facilitates the operator to move the fixed frame.

[0009] Preferably, the adjustment assembly includes two C-shaped bars, and the two C-shaped bars are respectively slidably arranged inside the vertical grooves of the two L-shaped grooves, and a square plate is fixedly provided at the bottom of the lower horizontal bar of the C-shaped bar, and the side surface of the square plate slides with the inside of the horizontal groove of the L-shaped groove, and the side surface of the square plate is fixed with a compression spring, one end of the compression spring is fixedly connected to the inside of the horizontal groove of the L-shaped groove, and the side surface of the upper horizontal bar of the L-shaped groove slides with the inside of one of the five rectangular grooves, and the slot and the rectangular slot are on the same parallel plane, and the C-shaped bar slides in the L-shaped groove to realize the unlocking or locking function, and the compression spring provides automatic reset locking force, and the upper horizontal bar of the C-shaped bar cooperates with the rectangular groove to lock the fixed frame position to clamp copper bars of different thicknesses, and the slot and the rectangular groove are on the same plane to ensure that the L-shaped rod can participate in height locking at the same time.

[0010] Preferably, a 45° bevel angle is provided on both sides of the lower horizontal bar of the C-shaped bar, a long groove is provided on the rear side of the inner wall of the movable groove, and a rack is fixedly provided on the side of the inner wall of the long groove. The side of the lower horizontal bar of the C-shaped bar slides with the side of the rack, and the bevel angle of the lower horizontal bar increases the contact area with the side of the rack, which is convenient for sliding with the side of the rack and pressing when resetting, and can generate strong friction to effectively lock the horizontal position of the square frame on the support seat.

[0011] Preferably, an L-shaped rod is fixedly provided on the side of the upper horizontal bar of the C-shaped bar, and the horizontal bar of the L-shaped rod passes through the interior of the square frame and slides with the interior of one of the three slots. The L-shaped rod can move synchronously with the C-shaped bar, and its horizontal rod can be inserted into different slots to cooperatively lock the height of the limit plate to ensure the accuracy of the bending position.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, by moving the two C-shaped bars forward, the two square plates are driven forward, the two compression springs are compressed, so that the lower horizontal bar of the C-shaped bar is released from contact with the rack, and the upper horizontal bar of the C-shaped bar is moved out of the rectangular groove. Then, the two copper bars are placed on the opposite sides of the two square frames, and the two fixed frames are moved to the left and right sides respectively to fix the copper bars. Then, the square frames are adjusted to move to an area where the bending rod is convenient for bending the copper bars.

At this time, the lower horizontal bar of the C-shaped bar moves to contact the side of the rack, and the upper horizontal bar of the C-shaped bar moves to a suitable rectangular groove. The position of the square frame on the upper side of the support seat can be adjusted, and copper bars of different thicknesses can be quickly bent, thereby increasing the efficiency of bending the copper bars.

[0014] In the present invention, after the two copper bars are fixed, the telescopic rod of the hydraulic cylinder drives the L-shaped plate to move up through the connecting block, and the two transverse grooves and the sliding groove limit the bending rod, so that when the L-shaped plate drives the inclined groove on its side to move upward, the two bending rods move to the left and right sides at the same time, thereby quickly squeezing the copper bar, squeezing the vertical copper bar into a bent state, and then being able to squeeze the two copper bars at the same time.

[0015] In the present invention, by moving the C-shaped bar forward to release the fixation of the square frame and the fixed frame, the C-shaped bar drives the L-shaped rod forward, so that the cross bar of the L-shaped rod moves out of the slot, thereby releasing the fixation between the square frame and the L-shaped block. Then, according to the position where the copper busbar needs to be bent, the limit plate is driven upward to a suitable height by the L-shaped block. Then, the C-shaped bar is relaxed, so that the C-shaped bar and the square plate drive the L-shaped block backward to a suitable slot through the second compression spring. The height of the limit plate can be quickly moved and fixed, thereby facilitating the bending of the copper busbar side at different heights. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by ordinary technical personnel in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10The present invention provides a technical solution: a copper busbar bending device for new energy vehicles, comprising a support base 1, a support frame 2 is fixedly provided on the top of the support base 1, a hydraulic cylinder 3 is fixedly provided on the top of the support base 1, a connecting block 10 is fixedly provided on the top of the hydraulic cylinder 3, a moving component 4 for bending the copper busbar is slidingly provided inside the support frame 2, square frames 5 are slidingly provided on the left and right sides of the top of the support base 1, an L-shaped bar 6 is fixedly provided on the bottom of the square frame 5, and moving grooves 7 are provided on the left and right sides of the front side of the support base 1, the interior of the moving groove 7 is slidably matched with the side surface of the horizontal plate of the L-shaped bar 6, the interior of the horizontal plate of the L-shaped bar 6 is provided with an L-shaped groove 8, and an adjustment component 9 is slidingly provided inside the L-shaped groove 8.

[0029] Example 1:

[0030] See also Figure 1 、 Figure 2 、 Figure 3 、 Figures 4 and 5 , this embodiment provides a technical solution:

[0031] The moving assembly 4 includes an L-shaped plate 401, which is slidably arranged inside the support frame 2. Two oblique grooves 402 are provided on the front side of the L-shaped plate 401. A rectangular plate 403 is fixedly provided in the middle of the top surface of the support base 1. Two transverse grooves 404 are provided on the front side of the rectangular plate 403. The two oblique grooves 402 are equal in length to the interior of the two transverse grooves 404. Sliding grooves 405 are provided on both the left and right sides of the front side of the support base 1. Two bending rods 406 are slidably provided inside the sliding grooves 405. The side surfaces of the bending rods 406 are respectively slidably engaged with the interior of the oblique grooves 402 and the transverse grooves 404.

[0032] A T-shaped stop block 407 is fixedly provided at the rear end of the bending rod 406, and a stop slot 408 is provided on the rear side of the inner wall of the sliding groove 405 to cooperate with the T-shaped stop block 407. Rectangular blocks 409 are fixedly provided on the left and right sides of the L-shaped plate 401, and guide grooves 4010 are provided on the left and right sides of the inner wall of the support frame 2 to cooperate with the rectangular blocks 409. The side surfaces of the horizontal plate of the L-shaped plate 401 are fixedly matched with the side surfaces of the connecting block 10.

[0033] The L-shaped plate 401 is rigidly connected to the L-shaped plate 401 and is moved upwards smoothly. The force of moving the two bending rods 406 along the guide of the sliding groove 405 and moving them horizontally to the left and right sides simultaneously and symmetrically enables the two bending rods 406 to expand outward quickly and synchronously from the center position. The direct action point of the outward expansion of the bending rods 406 is the copper bar to be processed on one side of the square frame 5. The outward movement of the bending rods 406 will apply a lateral bending force to the copper bar it contacts, thereby quickly and effectively bending the copper bar along the edge of the square frame 5 to perform the required bending forming. During this entire movement process, the specially designed T-shaped limit block 407 and the limit groove 408 that cooperate with it play a crucial stabilizing role. The T-shaped limit block 407 is embedded in the limit groove 408 and slides. This cooperation method effectively prevents any unnecessary up and down jumping, tilting or twisting of the bending rod 406 when moving in the sliding groove 405, ensuring that the movement trajectory of the bending rod 406 always remains strictly horizontal and straight when it is subjected to bending force, thereby ensuring the accuracy and operational stability of the copper bar bending process;

[0034] Example 2:

[0035] See also Figure 1 、 Figure 7 、 Figure 8 、 Figures 9 and 10 , this embodiment provides a technical solution:

[0036] The front and rear sides of the top surface of the square frame 5 are provided with stretching grooves 501. L-shaped blocks 502 are slidably provided on the side of the inner wall of the stretching groove 501. Limiting plates 505 are fixed on the tops of the two vertical blocks of the two L-shaped blocks 502. Three slots 504 are provided on the front side of the vertical block of the front L-shaped block 502.

[0037] A through slot 507 is provided in the middle of the inner wall of the square frame 5. A fixed frame 503 is slidably provided inside the through slot 507. Five rectangular slots 506 are provided in a straight line at equal distances on the front side of the fixed frame 503. The left side of the inner wall of the fixed frame 503 extends to the outside of the square frame 5.

[0038] The L-shaped block 502 is moved vertically, and the movement of the L-shaped block 502 directly drives the limit plate 505 fixed thereto to rise and fall synchronously. This lifting movement is highly adjustable, allowing the operator to accurately lift the limit plate 505 to a plurality of preset different height positions. In order to reliably lock the limit plate 505 at the selected height, when the cross bar of the L-shaped rod 904 is fully inserted into the slot 504 of the target height, the limit plate 505 can be fixed, effectively preventing the L-shaped block 502 and the limit plate 505 from accidentally moving in the vertical direction, thereby firmly fixing the limit plate 505 at the currently required height. The core function of this flexible hierarchical positioning mechanism is to enable the limit plate 505 to adaptively cover different target areas on the side of the copper busbar to be processed, thereby providing the necessary positioning basis for the subsequent precise bending operation of the copper busbar at a specified position. The clamping process of the copper busbar is the prerequisite for the bending operation. The operator first needs to place the copper busbar to be bent flatly so that The fixing frame 503 is then moved to move it toward the other side of the copper bar until the inner working surface of the fixing frame 503 is tightly pressed against the side surface of the copper bar. The clamping force applied simultaneously from both sides of the copper bar by the working side of the square frame 5 and the working side of the fixing frame 503 together forms an effective two-way constraint and positioning for the copper bar, ensuring that the copper bar remains in a stable position during the subsequent bending process under force and does not deviate or slide. After the fixing frame 503 is moved into position in a direction perpendicular to the surface of the copper bar according to the actual thickness of the current copper bar, the upper horizontal bar of the C-shaped bar 901 is inserted into the rectangular grooves 506 at different positions, so that the fixing frame 503 can be firmly locked in the final position where the clamping force is applied according to the thickness of the current copper bar. This locking effectively prevents the fixing frame 503 from loosening or retreating under the action of the external bending force, thereby reliably achieving stable clamping and fixation of copper bars of different thicknesses, providing a solid clamping guarantee for the subsequent bending process.

[0039] Example 3:

[0040] See also Figure 1 、、 Figure 2 、 Figure 7 、 Figure 8 、 Figures 9 and 10 , this embodiment provides a technical solution:

[0041] The adjustment assembly 9 includes two C-shaped bars 901, which are respectively slidably arranged inside the vertical grooves of the two L-shaped grooves 8. A square plate 902 is fixedly arranged on the bottom of the lower horizontal bar of the C-shaped bar 901. The side surface of the square plate 902 slides with the inside of the horizontal groove of the L-shaped groove 8. A compression spring 903 is fixedly arranged on the side surface of the square plate 902. One end of the compression spring 903 is fixedly connected to the inside of the horizontal groove of the L-shaped groove 8. The side surface of the upper horizontal bar of the L-shaped groove 8 slides with the inside of one of the five rectangular grooves 506. The slot 504 and the rectangular groove 506 are on the same parallel plane.

[0042] The left and right sides of the lower horizontal bar of the C-shaped bar 901 are both provided with a 45° bevel angle. The rear side of the inner wall of the movable groove 7 is provided with a long groove 701. The side of the inner wall of the long groove 701 is fixedly provided with a rack 702. The side of the lower horizontal bar of the C-shaped bar 901 is slidably engaged with the side of the rack 702.

[0043] An L-shaped rod 904 is fixedly provided on the side of the upper horizontal bar of the C-shaped bar 901. The horizontal bar of the L-shaped rod 904 passes through the interior of the square frame 5 and slides into the interior of one of the three slots 504.

[0044] In this embodiment, when the operator needs to adjust the equipment layout according to specific processing requirements or copper bars with large size differences, the operator can stretch the C-shaped bar 901 forward to release the lower horizontal bar of the C-shaped bar 901 from contact with the tooth surface of the rack 702, and then the specific position of the square frame 5 can be adjusted to adapt to those copper bars with large size and shape differences, which provides the basic conditions for subsequent reliable clamping and fixation. After the square frame 5 is accurately moved and positioned to the new target position on the upper side of the support base 1, it needs to be firmly locked again. At this time, the previous forward pulling force on the C-shaped bar 901 is released, thereby causing the lower horizontal bar of the C-shaped bar 901 to re-approach and finally align with the rack 70 2, the lower horizontal bar of the C-shaped bar 901 is beveled at both ends to increase the effective contact area between the lower horizontal bar and the side of the rack 702. When the beveled lower horizontal bar fits against the side wall of the rack 702, a relatively wide and stable contact area is formed between them. This large contact area, combined with the friction force on the tooth surface or side of the rack 702 and the possible self-locking effect, can generate a strong locking force after the C-shaped bar 901 moves backward into position. It is this force that effectively prevents any accidental sliding or displacement of the square frame 5 on its supporting surface, thereby stably and reliably fixing the square frame 5 in the new position after adjustment.

[0045] The use method and advantages of the present invention: When the copper busbar bending device for new energy vehicles is in operation and use, the working process is as follows:

[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown in the figure, by applying a pulling force to the two C-shaped bars 901, the C-shaped bar 901 and the square plate 902 are driven to move forward. The forward movement of the square plate 902 will compress the compression spring 903, causing it to produce elastic compression deformation. The lower horizontal bar of the C-shaped bar 901 moves forward as the whole moves forward, releasing the contact with the tooth surface of the rack 702, thereby releasing the locking constraint there. At the same time, the upper horizontal bar of the C-shaped bar 901 also synchronously slides out from the inside of the rectangular groove 506 processed on the side of the fixed frame 503. Then, according to the actual thickness of the two copper bars to be processed, one side of the copper bar is made to be close to the specified working surface of a square frame 5. By moving the two fixed frames 503 to the left and right respectively, each fixed frame 503 moves to the other side of its corresponding copper bar until its inner working surface is tightly pressed against the surface of the copper bar. The working surface of the fixed frame 503 applies a clamping force from both sides of the copper bar, and the two copper bars are firmly fixed on their respective work stations. Then, the square frame 5 and the copper bars on its sides are moved to the ideal area where the bending rod 406 is most convenient for applying the bending force to the target area of the copper bar. Finally, the forward thrust on the two C-shaped bars 901 is released at the same time. At this time, the two previously compressed compression springs 903 immediately release their stored elastic potential energy, generating a rebound force, so that the square plate 902 and the C-shaped bar 901 connected thereto are pushed backward as a whole to reset. At this time, the lower horizontal bar of the C-shaped bar 901 moves backward and fits with the side of the rack 702. At the same time, the upper horizontal bar of the C-shaped bar 901 moves backward and aligns with the appropriate rectangular groove 506, so that copper bars of different thicknesses can be quickly bent, which significantly improves the efficiency of the entire copper bar bending process.

[0047] After the operator firmly installs and fixes the two copper bars to be processed on the preset workstation, the bending action of the equipment starts immediately. At this time, the hydraulic cylinder 3, which serves as the core driving source, starts to work. Its telescopic rod extends smoothly under the action of hydraulic pressure. The end of the telescopic rod realizes force transmission and direction conversion through the connecting block 10. The connecting block 10 is directly connected to the L-shaped plate 401. Therefore, the linear motion of the telescopic rod of the hydraulic cylinder 3 is effectively converted into the upward movement of the L-shaped plate 401 as a whole in the vertical direction. The rise of the L-shaped plate 401 is not isolated. The movement of the bending rod 406 is controlled by a key bending rod 406 on each side. The movement trajectory of each bending rod 406 is subject to double constraints. One end of the bending rod 406 is precisely limited to slide in the transverse groove 404. At the same time, the rod body is guided to move in the sliding groove 405 opened on the L-shaped plate 401. The cooperation between the transverse groove 404 and the sliding groove 405 constitutes a precise restriction on the freedom of movement of the bending rod 406, ensuring that it can only move in the set left and right horizontal directions. As the L-shaped plate 401 is continuously driven upward by the hydraulic cylinder 3, the fixed The inclined groove 402 with a specific inclination angle on the side of the L-shaped plate 401 also rises synchronously, and the contact point on the bending rod 406 that cooperates with it is always in contact with the inclined surface of the inclined groove 402. Since the bending rod 406 is strictly restricted by the horizontal groove 404 and the sliding groove 405 to only move horizontally, when the inclined groove 402 moves upward, its inclined groove wall will force the part of the bending rod 406 in contact with it to produce a lateral displacement along the inclined surface, causing the two bending rods 406 to move horizontally to the left and right sides at the same time. The bending rod 406 exerts a strong, outward lateral extrusion force on the copper bar. This force quickly and effectively overcomes the elasticity of the copper bar material, forcing the central area of the copper bar, which was originally in a vertical state, to undergo plastic deformation and gradually be squeezed into the designed curved state. Since the two bending rods 406 move synchronously and symmetrically, this mechanism can efficiently and simultaneously apply bending force to the two copper bars fixed on the workstation, completing the bending process.

[0048] When the bending height needs to be adjusted, the C-shaped bar 901 is first moved forward, thereby driving the L-shaped rod 904 to move forward synchronously as a whole. The forward movement of the L-shaped rod 904 causes the horizontally extending crossbar portion to be completely removed from the inside of the slot 504. Once the crossbar of the L-shaped rod 904 is out of the slot 504, the mechanical interlock formed by the L-shaped rod 904, the slot 504 and the L-shaped block 502 is released. At this time, the operator can drive the L-shaped block 502 and the limit plate 505 on its upper side to move upward according to the specific position requirements of the current copper busbar to be bent. The limit plate 505 is lifted until it reaches a suitable position that matches the target bending height of the copper busbar side. After completing the height adjustment, the forward force on the C-shaped bar 901 is released. At this time, the second compression spring 90 installed in the mechanism 3 Immediately releases its stored elastic potential energy, generates a rebound force, and resets the square plate 902 and the C-shaped bar 901 connected thereto backward, while driving the L-shaped rod 904 to move backward synchronously. The L-shaped rod 904 moves backward, so that its crossbar portion automatically aligns with the slot 504 corresponding to the height of the current L-shaped block 502 and the limit plate 505 on the reset path, and accurately re-inserts itself into the interior of the slot 504. When the crossbar of the L-shaped rod 904 is completely and reliably inserted into the selected slot 504, a stable mechanical lock is formed, which firmly maintains the L-shaped block 502 and the limit plate 505 thereon at the newly adjusted new height, thereby enabling the working height of the limit plate 505 to be moved and fixed quickly and conveniently, thereby facilitating the bending of the copper busbar side at different heights.
