Bending method and bending device for copper bar flexible connection of new energy vehicle

Abstract

This invention discloses a bending method and device for flexible copper busbars used in new energy vehicles, relating to the field of workpiece bending processing technology. It includes a mounting base, with a first side plate fixed to the top of the mounting base. A fixed shaft is fixed to the side of the first side plate away from the mounting base. A bidirectional bending element for bending the flexible copper busbar is provided on the outer side of the fixed shaft. By setting the bidirectional bending element, when the clamping plate fixes one end of the copper busbar under the action of the clamping device, it pushes the end of the extending rod away from the fixed shaft. At this time, the clamping plate will rotate clockwise or counterclockwise along the center of the second side plate as the extending rod rotates. Simultaneously, because the extending rod, fixed shaft, and collar form a force-saving lever structure, the labor intensity of the workers is greatly reduced. The copper busbar can be bent upwards or downwards by rotating the clamping plate, thus achieving the effect of bidirectional bending of the copper busbar and improving the applicability of the equipment.

Description

Technical Field

[0001] This invention relates to the field of workpiece bending technology, specifically a bending method and device for flexible copper busbar connections used in new energy vehicles. Background Technology

[0002] New energy, also known as unconventional energy, refers to various forms of energy other than traditional energy. It refers to energy that has just begun to be developed and utilized or is being actively researched and is yet to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. New energy vehicles are beginning to replace traditional vehicles. New energy vehicles are energy-saving and environmentally friendly, and conform to green travel. With the continuous popularization of new energy vehicles, the motor and power supply device of new energy vehicles will be connected by soft copper busbars to supply power to the vehicle. At this time, the production and processing of soft copper busbars often requires certain bending treatment according to production requirements.

[0003] Generally, when bending soft copper busbars, one end of the soft copper busbar needs to be fixed, and then the unfixed end is folded up. This is not only cumbersome, but also limited by the fact that general bending equipment can only bend copper busbars in one direction. Summary of the Invention

The pull slider is slidably connected to the inner side of the guide groove. A tension spring connected to the transverse connecting block is provided on one side of the pull slider. The tension spring is located on the outer side of the transverse guide block. A U-shaped fixed frame is fixed at the end of the transverse guide block near the second side plate.

[0013] As a further aspect of the present invention: the furthest distance between the U-shaped fixed frame and the center of the second side plate is greater than the distance between the crossbar and the center of the second side plate.

[0014] This invention also discloses a method for bending flexible copper busbars for new energy vehicles, which uses the aforementioned bending device for flexible copper busbars in new energy vehicles and includes the following steps:

[0015] S1: When bending the soft copper busbar, first place the soft copper busbar between two clamping plates and two connecting plates;

[0016] S2: Rotate the worm gear. When the worm gear rotates, the worm wheel drives the rotating shaft and the follower shaft to rotate. When the rotating shaft rotates, it drives the drag-reducing roller to rotate. At this time, the rotation angle of the rotating shaft relative to the extension rod can be observed through the indicator and the measuring ring. After adjusting the included angle between the drag-reducing roller and the extension rod, hold one end of the extension rod and pull the pull slider at the same time.

[0017] S3: When the pull slider moves toward the end of the extension rod away from the second side plate, the U-shaped fixed frame pushes the shifting frame through the first inclined guide rail and the first guide post. At this time, the inner ring drives the outer ring to move toward the pressure plate, so that the second inclined guide rail can squeeze the second guide post. At this time, the clamping plate clamps and fixes one end of the soft copper busbar.

[0018] S4: Push the end of the extending rod away from the fixed shaft. At this time, the locking plate will rotate clockwise or counterclockwise along the center of the second side plate as the extending rod rotates. Since the extending rod, fixed shaft, and collar form a force-saving lever structure, the labor intensity of the workers is greatly reduced. The copper busbar can be folded up or down by rotating the locking plate, thereby achieving the effect of bidirectional folding of the copper busbar and improving the applicability of the equipment.

[0019] S5: When the soft copper busbar is rotated to the specified angle, the guide lock block will squeeze the drag-reducing roller through the inclined surface at one end. When the locking hole is aligned with the drag-reducing roller, one end of the locking pin will be inserted into the locking hole under the action of the return spring. This can limit the extension rod, thereby improving the accuracy of the equipment in bending the copper busbar.

[0020] S6: Release the pull slider so that the clamping plate loses its clamping and fixing of one end of the soft copper busbar;

[0021] S7: Remove the bent copper busbar.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By setting up a bidirectional folding component, after the clamping plate is fixed to one end of the copper busbar under the action of the clamping device, the end of the extending rod is pushed away from the fixed shaft. At this time, the clamping plate will rotate clockwise or counterclockwise along the center of the second side plate as the extending rod rotates. At the same time, since the extending rod, fixed shaft, and collar form a force-saving lever structure, the labor intensity of the workers is greatly reduced. The copper busbar can be folded up or down by rotating the clamping plate, thereby achieving the effect of bidirectional folding of the copper busbar and improving the applicability of the equipment.

[0024] 2. By setting up a clamping device, after placing the soft copper busbar between two clamping plates and two locking plates, hold one end of the extending rod and pull the pull slider at the same time. When the pull slider moves towards the end of the extending rod away from the second side plate, the U-shaped fixed frame pushes the shifting frame through the first inclined guide rail and the first guide post. At this time, the inner connecting ring drives the outer connecting ring to move towards the pressure plate, so that the second inclined guide rail can squeeze the second guide post. At this time, the clamping plate clamps and fixes one end of the soft copper busbar. When the extending rod rotates relative to the fixed axis, the inner connecting ring rotates relative to the outer connecting ring. The operation is simple and further improves the bending efficiency of the equipment for soft copper busbars.

[0025] 3. By setting an angle adjustment component, the worm gear is rotated before bending the soft copper busbar. The rotation of the worm gear drives the rotating shaft and the follower shaft to rotate. The rotating shaft, in turn, drives the drag-reducing roller. The rotation angle of the rotating shaft relative to the extending rod can be observed through the indicator and measuring ring. After adjusting the angle between the drag-reducing roller and the extending rod, the extending rod is pushed. When the soft copper busbar rotates to the specified angle, the guide locking block presses against the drag-reducing roller through its inclined surface. When the locking hole aligns with the drag-reducing roller, one end of the locking pin inserts into the locking hole under the action of the return spring. This limits the extension rod, improving the accuracy of the equipment's copper busbar bending and preventing subsequent use due to excessively large or small bending angles, thus increasing the yield of bent copper busbars.

The following describes embodiments of the invention based on its overall structure.

[0037] Please see Figures 1 to 8In this embodiment of the invention, a flexible copper busbar bending device for new energy vehicles includes a mounting base 1. A first side plate 2 is fixed to the top of the mounting base 1. A fixed shaft 3 is fixed to the side of the first side plate 2 away from the mounting base 1. A second side plate 4 is fixed to the end of the fixed shaft 3 away from the first side plate 2. A bidirectional bending member for bending the flexible copper busbar is provided on the outer side of the fixed shaft 3. A clamping plate 608 is connected to the fixed shaft 3 through the bidirectional bending member. A crossbar 5 is fixed to one end of the second side plate 4. A pressure plate 629 is slidably connected to the top of the crossbar 5. The bottom of the pressure plate 629 extends to the bottom of the crossbar 5. A clamping plate 607 is fixed to the bottom end of the pressure plate 629. A clamping device connected to the bidirectional bending member is provided on the outer side of the crossbar 5. The clamping device is used to clamp and fix one end of the flexible copper busbar. A connecting frame 601 located on the side of the first side plate 2 away from the fixed shaft 3 is provided on the top of the mounting base 1. An adjusting member connected to the first side plate 2 is provided on the top of the connecting frame 601.

[0038] In this embodiment: when bending the soft copper busbar, the soft copper busbar is first placed between two clamping plates 607 and two connecting plates 608. Then, the clamping device is operated to clamp and fix one end of the soft copper busbar with the clamping plate 607. The angle adjustment device is operated to control the bending angle of the copper busbar. Then, the bidirectional bending device is operated to fold the unfixed end of the copper busbar with the connecting plate 608. The bending angle of the copper busbar is precisely controlled by the cooperation of the bidirectional bending device and the angle adjustment device. Then, the clamping device is operated to make the clamping plate 607 lose its clamping and fixing of one end of the copper busbar. Then, the bent copper busbar is removed.

[0039] Please refer to this carefully. Figure 1 , Figure 2 , Figure 6 The bidirectional folding component includes a collar 606 rotatably connected to the outside of the fixed shaft 3 via a bearing. An extending rod 611 is fixed to the outside of the collar 606. A connecting plate 620 is fixed to one side of the first side plate 2. The connecting plate 620 is located on the side of the fixed shaft 3 away from the extending rod 611. A transverse connecting block 609 is fixed to the side of the extending rod 611 away from the first side plate 2. A snap-fit ​​plate 608 is disposed at one end of the transverse connecting block 609. An arc-shaped fixed rod 619 is fixed to the outside of the connecting plate 620. The extending rod 611 is slidably connected to the outside of the arc-shaped fixed rod 619. The center of the arc-shaped fixed rod 619 is coaxial with the center of the fixed shaft 3. An arc-shaped spring 621 connected to the extending rod 611 is disposed on the outside of the connecting plate 620. The arc-shaped spring 621 is sleeved on the outside of the arc-shaped fixed rod 619.

[0040] In this embodiment: after the clamping plate 607 fixes one end of the copper busbar under the action of the clamping device, the extension rod 611 is pushed away from the fixed shaft 3. At this time, the locking plate 608 will rotate clockwise or counterclockwise along the center of the second side plate 4 as the extension rod 611 rotates. At the same time, since the extension rod 611, the fixed shaft 3, and the collar 606 form a force-saving lever structure, the labor intensity of the workers is greatly reduced. The copper busbar can be folded up or down by the rotation of the locking plate 608, so as to achieve the effect of bidirectional folding of the copper busbar, which improves the applicability of the equipment. After the bent copper busbar is removed, the extension rod 611 will be restored under the elastic restoring force of the arc spring 621, so that the transverse central axis of the extension rod 611 is coaxial with the transverse central axis of the arc fixed rod 619, which provides convenience for the subsequent use of the equipment.

[0041] Please refer to this carefully. Figure 1 , Figure 2 The extension rod 611 is sleeved on the outside of the arc-shaped fixed rod 619. The distance from the locking plate 608 to the center of the fixed axis 3 is less than the distance from one end of the extension rod 611 to the center of the fixed axis 3.

[0042] In this embodiment, by setting this structure, a force-saving lever effect is formed between the extension rod 611, the connecting plate 608, and the fixed shaft 3, thereby reducing the labor intensity of the workers.

[0043] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 7 The clamping device includes a second guide post 628 rotatably connected to the top of the pressure plate 629 via a bearing. A transverse connecting block 631 is slidably connected to the inner side of the pressure plate 629. A second inclined guide rail 630 is provided on the inner side of the transverse connecting block 631. The second guide post 628 is located inside the second inclined guide rail 630. An outer connecting ring 622 is fixed to the end of the transverse connecting block 631 away from the pressure plate 629. An inner connecting ring 624 is rotatably connected to the inner side of the outer connecting ring 622 via a bearing. A shifting frame 626 is fixed to the end of the inner connecting ring 624 away from the pressure plate 629. A first guide post 625 is rotatably connected to the bottom of the shifting frame 626 via a shaft. A transverse connecting block 609 is provided on one side. A horizontal guide block 618 extends through to the other side of the horizontal connecting block 609. A pull slider 610 is fixed at the end of the horizontal guide block 618 away from the second side plate 4. A guide groove 612 is provided on the outer side of the extension rod 611. The pull slider 610 is slidably connected to the inner side of the guide groove 612. A tension spring 613 connected to the horizontal connecting block 609 is provided on one side of the pull slider 610. The tension spring 613 is located on the outer side of the horizontal guide block 618. A U-shaped fixed frame 623 is fixed at the end of the horizontal guide block 618 near the second side plate 4. A first inclined guide rail 627 is provided at one end of the U-shaped fixed frame 623. A first guide post 625 is slidably connected to the inner side of the first inclined guide rail 627.

[0044] In this embodiment: After placing the soft copper busbar between two clamping plates 607 and two connecting plates 608, hold one end of the extending rod 611 and simultaneously pull the pull slider 610. When the pull slider 610 moves towards the end of the extending rod 611 away from the second side plate 4, the U-shaped fixed frame 623 pushes the shifting frame 626 through the first inclined guide rail 627 and the first guide post 625. At this time, the inner connecting ring 624 drives the outer connecting ring 622 to move towards the pressure plate 629, so that the second inclined guide rail 630 can squeeze the second guide post 628. At this time, the clamping plate 607 clamps and fixes one end of the soft copper busbar. When the extending rod 611 rotates relative to the fixed axis 3, the inner connecting ring 624 rotates relative to the outer connecting ring 622. The operation is simple and further improves the bending efficiency of the soft copper busbar.

[0045] Please refer to this carefully. Figure 7 The inner side of the pressure plate 629 is provided with a guide groove that matches the transverse connecting block 631. The second guide post 628 matches the second inclined guide rail 630, and the first inclined guide rail 627 matches the first guide post 625.

[0046] In this embodiment: by setting this structure, when the first inclined guide rail 627 presses the first guide post 625, the transverse connecting block 631 presses the second guide post 628 through the second inclined guide rail 630, thus ensuring the stability of the movement of the clamping plate 607.

[0047] Please refer to this carefully. Figure 1 , Figure 2 , Figure 4 , Figure 8 The adjusting component includes a rotating shaft 605 rotatably connected to the side of the first side plate 2 away from the fixed axis 3 via a bearing. A locking pin 634, extending through to the bottom of the rotating shaft 605, is inserted into the top of the first guide post 625. A return spring 635, connected to the rotating shaft 605, is located at the bottom of the locking pin 634. A drag-reducing roller 632 is located at the top of the locking pin 634. A worm gear 604 is fixed to the end of the rotating shaft 605 away from the first side plate 2. A follower shaft 633 is fixed to one end of the worm gear 604. The follower shaft 633 extends to the side of the connecting frame 601 away from the first side plate 2 and rotates... A measuring ring 603 is installed on one side of the coupling 633. An indicator 602 is fixed to one end of the rotating coupling 633. A worm gear 617 is installed on the side of the connecting frame 601 away from the measuring ring 603. The worm gear 617 is located below the worm wheel 604 and meshes with the worm wheel 604. A T-shaped plug 615 is inserted into the side of the extension rod 611 away from the transverse connecting block 609. Locking springs 614 connected to the extension rod 611 are provided on both sides of the T-shaped plug 615. A guide lock block 616 is fixed to one end of the T-shaped plug 615. A locking hole 636 is opened at one end of the guide lock block 616.

[0048] In this embodiment: before bending the soft copper busbar, the worm gear 617 is rotated. The rotation of the worm gear 617 causes the worm wheel 604 to drive the rotating shaft 605 and the follower shaft 633 to rotate. When the rotating shaft 605 rotates, it drives the drag-reducing roller 632 to rotate. At this time, the rotation angle of the rotating shaft 605 relative to the extension rod 611 can be observed through the indicator 602 and the measuring ring 603. After adjusting the included angle between the drag-reducing roller 632 and the extension rod 611, the extension rod 611 is pushed. When the soft copper busbar rotates to the specified angle, the guide lock block 616 will enter the drag-reducing roller 632 through the inclined surface at one end. When the clamping pin 634 is aligned with the drag-reducing roller 632 during the pressing process, one end of the clamping pin 634 will be inserted into the clamping pin 636 under the action of the return spring 635. This limits the position of the extension rod 611, thereby improving the accuracy of the equipment in bending the copper busbar and preventing subsequent use from being affected by the large or small bending angle. This also improves the yield of the bent copper busbar. After the soft copper busbar is bent, the drag-reducing roller 632 can be separated from the clamping pin 636 by pulling the guide locking block 616. When the extension rod 611 returns to its original position, the guide locking block 616 will also return to its original position, which provides convenience for the subsequent use of the equipment.

[0049] Please refer to this carefully. Figure 4 The locking hole 636 extends from one end of the guide locking block 616 to the other end of the guide locking block 616, and the drag-reducing roller 632 is on the same plane as the locking hole 636.

[0050] In this embodiment, the drag-reducing roller 632 and the locking hole 636 can be misaligned by pulling the guide locking block 616, thereby causing the drag-reducing roller 632 to lose its limiting effect on the distance-increasing rod 611. This allows the guide locking block 616 to be restored, providing convenience for the subsequent use of the equipment.

[0051] Please refer to this carefully. Figure 4 , Figure 8 The pointed end of the indicator 602 points in the same direction as the drag-reducing roller 632 at the top of the locking pin 634, and a through hole larger than the rotating coupling 633 is provided on one side of the connecting frame 601.

[0052] In this embodiment, this structure is set up to prevent the connecting frame 601 from obstructing the rotation of the rotating shaft 633. At the same time, the rotation angle of the drag-reducing roller 632 relative to the distance-increasing rod 611 can be clearly known by the direction of the sharp corner of the indicator 602.

[0053] Please refer to this carefully. Figure 3 The furthest distance between the U-shaped fixed frame 623 and the center of the second side plate 4 is greater than the distance between the crossbar 5 and the center of the second side plate 4.

[0054] In this embodiment, this structure is designed to prevent the U-shaped fixed frame 623 from contacting the crossbar 5 when it rotates relative to the second side plate 4, thereby improving the smoothness of the rotation of the distance extender 611.

[0055] The following describes a method for bending copper busbars for new energy vehicles, based on the aforementioned bending device. The method includes the following steps:

[0056] S1: When bending the soft copper busbar, first place the soft copper busbar between the two clamping plates 607 and the two connecting plates 608.

[0057] S2: Rotate the worm gear 617. The rotation of the worm gear 617 causes the worm wheel 604 to drive the rotating shaft 605 and the follower shaft 633 to rotate. When the rotating shaft 605 rotates, it can drive the drag-reducing roller 632 to rotate. At this time, the rotation angle of the rotating shaft 605 relative to the distance increasing rod 611 can be observed through the indicator 602 and the measuring ring 603. After adjusting the included angle between the drag-reducing roller 632 and the distance increasing rod 611, hold one end of the distance increasing rod 611 and pull the pull slider 610 at the same time.

[0058] S3: When the pull slider 610 moves toward the end of the extension rod 611 away from the second side plate 4, the U-shaped fixed frame 623 pushes the shift frame 626 through the first inclined guide rail 627 and the first guide post 625. At this time, the inner connecting ring 624 drives the outer connecting ring 622 to move toward the pressure plate 629, so that the second inclined guide rail 630 can squeeze the second guide post 628. At this time, the clamping plate 607 clamps and fixes one end of the soft copper busbar.

[0059] S4: Push the end of the extending rod 611 away from the fixed shaft 3. At this time, the locking plate 608 will rotate clockwise or counterclockwise along the center of the second side plate 4 as the extending rod 611 rotates. Since the extending rod 611, the fixed shaft 3, and the collar 606 form a force-saving lever structure, the labor intensity of the workers is greatly reduced. The copper busbar can be folded up or down by rotating the locking plate 608, so as to achieve the effect of bidirectional folding of the copper busbar and improve the applicability of the equipment.

[0060] S5: When the soft copper busbar is rotated to the specified angle, the guide lock block 616 will press the drag-reducing roller 632 through the inclined surface at one end. When the locking hole 636 is aligned with the drag-reducing roller 632, one end of the locking pin 634 will be inserted into the locking hole 636 under the action of the return spring 635. In this way, the extension rod 611 can be limited, thereby improving the accuracy of the equipment for bending the copper busbar.

[0061] S6: Release the pull slider 610 so that the clamping plate 607 loses its clamping and fixing of one end of the soft copper busbar;

[0062] S7: Remove the bent copper busbar.

[0063] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
