Description

Technical Field

[0001] This utility model relates to the field of bending machines, and in particular to a bending machine for electric vehicle wires. Background Technology

[0002] Electric vehicle (EV) conductors are a crucial component of the EV's high-voltage electrical system, responsible for the safe and efficient transmission of electrical energy. In these systems, aluminum busbars are commonly used for internal battery pack connections, busbars, or high-current transmission applications. Due to actual manufacturing needs, some EV conductors require bending the aluminum busbar section after ultrasonic welding of two sections.

[0003] The existing authorized publication number is CN220278137U, which discloses a wire bending device. The wire bending device includes: a cam, which is rotatable between a first position and a third position, and the cam also has a second position between the first position and the third position; a driving device, which is drivenly connected to the cam; two clamping blocks, at least one of which is drivenly connected to the cam; and a bending member, which is disposed on the cam and offset from the rotation axis of the cam. In the first position, there is a gap between the two clamping blocks suitable for the wire to pass through and the bending member is spaced apart from the wire. In the second position, the two clamping blocks jointly clamp the wire. During the process of the cam rotating from the second position to the third position, the bending member is adapted to bend the wire to a predetermined angle.

[0004] The existing technology can only bend flat conductors laterally. It cannot meet the requirement of bending flat conductors vertically. There is an urgent need to develop a device that can bend flat conductors both laterally and vertically. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric vehicle wire bending machine to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an electric vehicle wire bending machine, comprising:

[0007] The material conveying mechanism is used to carry the wire and transport it to the bending position. It is equipped with a clamping mechanism and guide wheels at the end of its operation.

[0008] A lateral bending mechanism is vertically installed at the discharge end of the material conveying mechanism and is used to laterally bend the wire.

[0009] The vertical bending mechanism is horizontally positioned at the discharge end of the material conveying mechanism, perpendicular to the horizontal bending mechanism. A clamping mechanism is symmetrically positioned opposite the vertical bending mechanism. The vertical bending mechanism, in conjunction with the clamping mechanism, clamps the wire and bends it vertically.

[0010] Preferably, the horizontal bending mechanism and the vertical bending mechanism have the same structure, both including a lead screw moving module, a drive unit, a bending head, and a bending wheel. The free end of the lead screw moving module is equipped with the drive unit, and the output end of the drive unit is connected to the bending wheel. The bending wheel is located on the outer surface of the bending head and achieves the bending process of the wire by rotating along the outer contour of the bending head through the drive unit.

[0011] Preferably, the drive unit includes a servo motor, a first gear, a second gear, an inner fixed shaft, and an outer rotating shaft. The outer rotating shaft is rotatably mounted on the inner fixed shaft via multiple bearings and connected to the second gear. The bending head is mounted on the inner fixed shaft, and the bending wheel is mounted on the side of the outer rotating shaft. The servo motor drives the first gear to rotate, causing the second gear meshing with it to rotate synchronously, thereby realizing the bending process of the wire by rotating the bending wheel along the outer contour of the bending head.

[0012] The clamping mechanism includes a second lead screw moving module, an assembly block, and a pressure block. The pressure block is rotatably mounted on the assembly block via a rod body, and the assembly block is detachably mounted on the free end of the second lead screw moving module.

[0013] Preferably, the free end of the lead screw moving module is connected to a U-shaped plate, which moves synchronously with the drive unit. One side of the U-shaped plate is provided with a material support to support the wire that extends out after bending.

[0014] Preferably, the material support includes a lifting unit, a T-shaped plate, and a bracket. The lifting unit is assembled on the U-shaped plate, the T-shaped plate is assembled on the free end of the lifting unit assembly, and the bracket is assembled on the top of the T-shaped plate.

[0015] Preferably, the material conveying mechanism includes a support plate mounted on a frame, linear guide rails on both sides of the top surface of the support plate, a platform slidably mounted on the linear guide rails, a material tray detachably mounted on the top surface of the platform, a toothed rack on the side of one of the linear guide rails, a motor vertically mounted on one side of the platform, and a gear meshing with the toothed rack at the output end of the motor.

[0016] Preferably, the clamping mechanism includes a cylinder mounted on the top surface of the platform and a fixed template detachably mounted on one end of the platform. A movable template is hinged to one side of the fixed template, and the movable template and the fixed template form a scissor-like structure. A spring is provided between the other ends of the movable template and the fixed template. Under the tension of the spring, one end of the movable template in the initial state is separated from the fixed template. The piston of the cylinder is connected to an arc-shaped push block, which is used to push the movable template to rotate along the hinge axis so that one end of the movable template is close to the fixed template to clamp the wire.

[0017] Preferably, the clamping mechanism further includes a guide block disposed at one end of the top surface of the fixed template, and a groove for guiding through is provided on one side of the guide block. The clamping mechanism also includes two limiting blocks disposed at one end of the guide block, and the two limiting blocks are spaced apart by a gap for guiding through.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The horizontal bending mechanism and the vertical bending mechanism of this utility model operate alternately, which can perform horizontal bending of the aluminum busbar of the conductor and vertical bending of the aluminum busbar. This allows the equipment to meet the requirements of both horizontal and vertical bending of the aluminum busbar of the conductor, and the whole process is automated, which greatly improves the efficiency of the guiding bending operation.

[0020] 2. This utility model adds a pressing mechanism to the opposite side of the vertical bending mechanism. During bending, the vertical bending mechanism and the pressing mechanism work together to press the aluminum strip together. When the vertical bending mechanism bends, the pressing mechanism rotates together with the vertical bending mechanism, which effectively avoids wrinkles on the aluminum strip and improves the bending effect of the aluminum strip.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0032] This utility model provides an electric vehicle wire bending machine, such as Figure 1-9 As shown, it includes:

[0033] 1. Frame, 2. Material conveying mechanism, 3. Horizontal bending mechanism, 4. Vertical bending mechanism, 5. Pressing mechanism, 6. Material support, 7. Guide wheel, 8. Clamping mechanism.

[0034] The material conveying mechanism 2 is horizontally mounted on the frame 1 to carry the wire and transport it to the bending position. A clamping mechanism 8 and a guide wheel 7 are provided at the running end of the material conveying mechanism 2. The horizontal bending mechanism 3 is vertically mounted at the discharge end of the material conveying mechanism 2 to bend the wire horizontally. The vertical bending mechanism 4 is horizontally mounted at the discharge end of the material conveying mechanism 2 and is perpendicular to the horizontal bending mechanism 3. A pressing mechanism 5 is provided opposite the vertical bending mechanism 4 and is symmetrical to it. The vertical bending mechanism 4 cooperates with the pressing mechanism 5 to clamp the wire and bend it vertically.

[0035] During operation, the flexible part of the conductor is placed on the material conveying mechanism 2, and the aluminum busbar is passed through the guide wheel 7 and the clamping mechanism 8 for limiting and clamping. The horizontal bending mechanism 3 and the vertical bending mechanism 4 operate alternately, which can perform horizontal bending or vertical bending of the aluminum busbar of the conductor. This allows the equipment to meet the horizontal and vertical bending operations of the aluminum busbar of the conductor, and the whole process is automated, which greatly improves the efficiency of the guiding bending operation.

[0036] Meanwhile, since the aluminum strip is flat, it is prone to wrinkling when bent vertically. Therefore, a pressing mechanism 5 is added opposite to the vertical bending mechanism 4. During bending, the vertical bending mechanism 4 and the pressing mechanism 5 work together to press the aluminum strip together. When the vertical bending mechanism 4 bends, the pressing mechanism 5 rotates with the vertical bending mechanism 4, which effectively avoids wrinkling of the aluminum strip and improves the bending effect of the aluminum strip.

[0037] In this embodiment, the horizontal bending mechanism 3 and the vertical bending mechanism 4 have the same structure, both including a lead screw moving module 31, a drive unit, a bending head 37, and a bending wheel 38. The free end of the lead screw moving module 31 is equipped with the drive unit, and the output end of the drive unit is connected to the bending wheel 38. The bending wheel 38 is located on the outer surface of the bending head 37 and is rotated along the outer contour of the bending head 37 by the drive unit to achieve the bending process of the wire.

[0038] During lateral bending, the lead screw moving module 31 of the lateral bending mechanism 3 drives the driving unit to move up to the guide wheel 7, so that the bending head 37 is aligned with the guide wheel 7. The aluminum busbar is continuously fed by the material conveying mechanism 2 to move to the bending head 37. Then the driving unit can drive the bending wheel 38 along the outer contour of the bending head 37, that is, the bending wheel 38 rotates around the center of the bending head 37 to realize the lateral bending of the aluminum busbar.

[0039] During vertical bending, the lead screw moving module 31 drives the horizontal bending mechanism 3 to move downward, causing the bending head 37 to exit in front of the guide wheel 7. At this time, the lead screw moving module 31 of the vertical bending mechanism 4 drives the water tank of the drive unit to move towards the guide wheel 7. At the same time, the clamping mechanism 5 also moves towards the guide wheel 7 until the bending head 37 cooperates with the clamping mechanism 5 to clamp the aluminum busbar. Then, the drive unit can drive the bending wheel 38 along the outer contour of the bending head 37, that is, the bending wheel 38 rotates around the center of the bending head 37 to realize the vertical bending of the aluminum busbar.

[0040] In this embodiment, the drive unit includes a servo motor 32, a first gear 33, a second gear 34, an inner fixed shaft 35, and an outer rotating shaft 36. The outer rotating shaft 36 is rotatably mounted on the inner fixed shaft 35 via multiple bearings and is connected to the second gear 34. The bending head 37 is mounted on the inner fixed shaft 35, and the bending wheel 38 is mounted on the side of the outer rotating shaft 36. The servo motor 32 drives the first gear 33 to rotate, causing the second gear 34 meshing with it to rotate synchronously, thereby realizing the bending process of the wire by the bending wheel 38 rotating along the outer contour of the bending head 37.

[0041] The driving principle is as follows: the servo motor 32 drives the gear 33 to rotate. Since the gear 33 meshes with the gear 34, it synchronously drives the gear 34 to rotate. The gear 34 is connected to the outer rotating shaft 36 and rotates with the gear 34 under the action of the bearing. This causes the bending wheel 38 connected to its outer side to move along the periphery of the bending head 37, thereby bending the aluminum strip inside the bending head 37.

[0042] In this embodiment, the clamping mechanism 5 includes a second lead screw moving module 51, an assembly block 52, and a pressure block 53. The pressure block 53 is rotatably mounted on the assembly block 52 via a rod body, and the assembly block 52 is detachably mounted on the free end of the second lead screw moving module 51.

[0043] It can be noted that the second lead screw moving module 51 and the first lead screw moving module 31 adopt the same structure. Its main components include a motor, lead screw, guide mechanism, nut, support base and bearing. It mainly utilizes the fact that when the motor drives the lead screw to rotate, the nut cannot rotate due to the constraint of the guide mechanism and is forced to move along the lead screw axis. The lead screw moving module is existing technology and will not be described in detail again.

[0044] When the clamping mechanism 5 works in conjunction with the vertical bending mechanism 4 to perform vertical bending, both use the lead screw moving module to move synchronously to the guide wheel 7 position, so that the clamped aluminum strip is always located between the two guide wheels 7. When clamped, the pressure block 53 and the bending head 37 are tightly fitted to prevent the aluminum strip from moving or wrinkling during bending.

[0045] In this embodiment, a U-shaped plate is connected to the free end of the lead screw moving module 31. The U-shaped plate moves synchronously with the drive unit. A material support 6 is provided on one side of the U-shaped plate to support the wire that extends out after bending.

[0046] Specifically, the material support 6 includes a lifting unit 61, a T-shaped plate 62, and a bracket 63. The lifting unit 61 is assembled on the U-shaped plate, the T-shaped plate 62 is assembled on the free end of the lifting unit 61, and the bracket 63 is assembled on the top of the T-shaped plate 62.

[0047] When the aluminum busbar is bent, the lifting unit 61 lifts the T-shaped plate 62 upward until the bracket 63 contacts the supporting aluminum busbar, effectively supporting the wire and preventing the wire from bending due to its weight.

[0048] It should be noted that the lifting unit 61 is a linear module, which is vertically assembled and used to drive the T-shaped plate 62 to move up and down.

[0049] In this embodiment, the material conveying mechanism 2 includes a support plate 21 mounted on the frame 1. Linear guide rails 22 are provided on both sides of the top surface of the support plate 21. A platform 23 is slidably mounted on the linear guide rails 22. A material tray 26 is detachably mounted on the top surface of the platform 23. A toothed rack 24 is provided on the side of one of the linear guide rails 22. A motor 25 is vertically mounted on one side of the platform 23. The output end of the motor 25 is connected to a gear that meshes with the toothed rack 24.

[0050] Specifically, the flexible part of the wire is placed on the material tray 26. When the material is moved, the motor 25 drives the gear to rotate. Under the action of the sliding assembly between the linear guide rail 22 and the platform 23, the motor 25 drives the gear to move linearly along the toothed rack 24, so that the platform 23 moves horizontally on the linear guide rail 22, thereby driving the material tray 26 to move closer to the bending position.

[0051] In this embodiment, the clamping mechanism 8 includes a cylinder 81 mounted on the top surface of the platform 23 and a fixed template 82 detachably mounted on one end of the platform 23. A movable template 83 is hinged to one side of the fixed template 82. The movable template 83 and the fixed template 82 form a scissor-like structure. A spring 85 is provided between the other ends of the movable template 83 and the fixed template 82. Under the tension of the spring 85, one end of the movable template 83 in the initial state is separated from the fixed template 82. The piston of the cylinder 81 is connected to an arc-shaped push block 84, which is used to push the movable template 83 to rotate along the hinge axis so that one end of the movable template 83 is close to the fixed template 82 to clamp the wire.

[0052] Specifically, during clamping, cylinder 81 pushes arc-shaped push block 84 to move towards the hinge position of fixed template 82 and moving template 83. Arc-shaped push block 84 continuously feeds and pushes moving template 83, so that one end of moving template 83 gradually approaches one end of fixed template 82, thereby clamping the aluminum strip. After bending, cylinder 81 resets, and under the pulling force of spring 85, the other end of moving template 83 moves towards the other end of fixed template 82, so that the wire can be removed.

[0053] In this embodiment, the clamping mechanism 8 further includes a guide block 86 disposed at one end of the top surface of the fixed template 82. A groove for guiding passage is provided on one side of the guide block 86. The clamping mechanism 8 also includes two limiting blocks 87 disposed at one end of the guide block 86. The two limiting blocks 87 are spaced apart by a gap for guiding passage.

[0054] Specifically, before clamping, the aluminum strip needs to be limited by the groove of the guide block 86 and the two limiting blocks 87, so that the clamped aluminum strip always maintains its original position, that is, the center of the bending position, so as to align with the horizontal bending mechanism 3 and the vertical bending mechanism 4.

[0055] The working principle of this utility model is as follows: the soft wire part of the conductor is placed on the material tray 26, and the aluminum strip part is passed through the guide wheel 7. When bending, the aluminum strip is first clamped by the clamping mechanism 8.

[0056] During lateral bending, the lead screw moving module 31 of the lateral bending mechanism 3 drives the drive unit to move up to the guide wheel 7, so that the bending head 37 is aligned with the guide wheel 7. Then, the servo motor 32 drives the gear 33 to rotate. Since the gear 33 meshes with the gear 34, it synchronously drives the gear 34 to rotate. The gear 34 is connected to the outer rotating shaft 36 and rotates with the gear 34 under the action of the bearing, so that the bending wheel 38 connected to its outer side moves along the periphery of the bending head 37, thereby performing lateral bending on the aluminum strip inside the bending head 37.

[0057] During vertical bending, the lead screw moving module 31 drives the horizontal bending mechanism 3 to move downward, causing the bending head 37 to exit in front of the guide wheel 7. At this time, the lead screw moving module 31 of the vertical bending mechanism 4 drives the water tank of the drive unit to move towards the guide wheel 7. At the same time, the clamping mechanism 5 also moves towards the guide wheel 7 until the bending head 37 cooperates with the clamping mechanism 5 to clamp the aluminum busbar. Then, the drive unit drives the bending wheel 38 to move along the periphery of the bending head 37 to realize the vertical bending of the aluminum busbar.

[0058] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.

[0059] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
