Description

Technical Field

[0001] The present application relates to the technical field of metal aluminum bar straightening, and specifically to a high-voltage aluminum bar straightening device for new energy vehicles. Background Art

[0002] High-voltage aluminum bars are generally used as connecting materials in new energy vehicles. They are commonly used as wires in the battery management system and charging system of new energy vehicles. The high-voltage aluminum bars connect the battery pack and the motor of the vehicle. By straightening the high-voltage aluminum bars, good contact between the high-voltage aluminum bars and the connectors can be ensured to avoid increased resistance and potential overheating risks caused by poor contact, and to reduce the occurrence of local overheating caused by current concentration in a certain area.

[0003] Referring to the Chinese patent application document with the patent application publication number CN116475274A, entitled A conductive aluminum bar bending processing equipment for new energy vehicles, the device bends several groups of high-voltage aluminum bars by setting a pressure plate, a receiving plate and a pressure part to achieve the connection of the high-voltage aluminum bars at different parts, and drives several groups of aluminum sheets to move synchronously through a horizontal bar.

[0004] According to the above technical scheme, before the newly produced aluminum bar is made into a high-voltage conductive aluminum bar, a series of processing is required on the produced aluminum bar, including straightening the aluminum bar. A straightening machine is usually used to straighten the aluminum bar. When straightening the aluminum bar, due to the length limitation of the aluminum bar, the aluminum bar that has been extended in front will have a slight rebound. The slight rebound will cause the aluminum bar to warp up or bend down during the forward movement. When the aluminum bar is warped up, the guide roller cannot support the subsequent aluminum bar, resulting in a large load on the straightening roller on the straightening machine, which affects the subsequent straightening quality of the aluminum plate. When the aluminum bar bends down, it is easy to collide with the guide roller, causing damage to both the guide roller and the aluminum bar. Summary of the invention

[0005] In view of this, the present application provides a high-pressure aluminum bar straightening device for new energy vehicles, aiming to solve the problem of the aluminum bar rebounding and bending again due to length limitation after straightening.

On one side of the machine 1, the second clamping mechanism can move synchronously with the movement of the high-pressure aluminum bar, wherein a moving spring 46 is provided in the first clamping mechanism and the second clamping mechanism. In the present embodiment, the second clamping mechanism is arranged as a single group, which can be increased or decreased according to the actual length of the high-pressure aluminum bar in actual use. The supporting mechanism 4 is used to push the first clamping mechanism and the second clamping mechanism to move toward the upper position of the straightening roller 11, and the synchronization mechanism 5 is arranged on the second clamping mechanism, and the synchronization mechanism 5 is used to drive the second clamping mechanism and the high-pressure aluminum bar to move synchronously.

[0035] like Figure 2 As shown, the first clamping mechanism includes a fixed frame 2, a first clamping platform 21, a first clamping roller 22, a second clamping platform 23 and a second clamping roller 24. The fixed frame 2 is slidably connected to the connecting plate 14, the first clamping platform 21 is fixedly connected to the fixed frame 2, the first clamping roller 22 is rotatably connected to the first clamping platform 21, and the initial height of the first clamping roller 22 is located above the high-pressure aluminum row, the second clamping platform 23 is slidably connected to the fixed frame 2, and is arranged on a side close to the connecting plate 14, the second clamping platform 23 is fixedly connected to one end of the movable spring 46, and the movable spring 46 is fixedly connected to the fixed frame 2, the second clamping roller 24 is rotatably connected to the second clamping platform 23, and the second clamping roller 24 is arranged toward one side of the first clamping roller 22. When the high-pressure aluminum bar is straightened by the straightening roller 11 on the straightening machine 1 and then extended, the second clamping roller 24 abuts against the bottom side of the high-pressure aluminum bar, and the first clamping roller 22 abuts against the top side of the high-pressure aluminum bar, and during the movement of the high-pressure aluminum bar, the first clamping roller 22 and the second clamping roller 24 rotate synchronously, and the second clamping roller 24 is always pushed by the moving spring 46 to maintain an upward state during this process, so that the first clamping roller 22 and the second clamping roller 24 always remain in a clamped state during this process.

[0036] like Figure 4 As shown, the second clamping mechanism includes a sliding frame 3, a third clamping platform 31, a third clamping roller 32, a fourth clamping platform 33 and a fourth clamping roller 34. The sliding frame 3 is slidably connected to the sliding plate 16, the third clamping platform 31 is arranged at the top position of the sliding frame 3, the third clamping roller 32 is rotatably connected to the third clamping platform 31, and the initial height of the third clamping roller 32 is located above the high-pressure aluminum row, the fourth clamping platform 33 is fixedly connected to one end of the movable spring 46, and the movable spring 46 is fixedly connected to the sliding frame 3, the fourth clamping platform 33 is slidably connected to the sliding frame 3, and is arranged on the side close to the sliding plate 16, the fourth clamping roller 34 is rotatably connected to the fourth clamping platform 33, and the fourth clamping roller 34 is arranged toward the side of the third clamping roller 32. When the high-pressure aluminum bar moves out from the middle position between the first clamping roller 22 and the second clamping roller 24, the third clamping roller 32 abuts against the top side of the high-pressure aluminum bar, and the fourth clamping roller 34 abuts against the bottom side of the high-pressure aluminum bar, and during the movement of the high-pressure aluminum bar, the sliding plate 16 and the high-pressure aluminum bar are driven to move synchronously through the synchronization mechanism 5.

[0037] like Figure 3As shown, the support mechanism 4 includes a damping shell 41, a support spring 42, a support rod 43 and a damping inner shell 44. The damping shell 41 is fixedly connected to the connecting plate 14 and the sliding plate 16, and multiple damping shells 41 are arranged on the connecting plate 14 and the sliding plate 16. The support spring 42 is fixedly connected to the inside of the damping shell 41, the support rod 43 is fixedly connected to the fixed frame 2 and the sliding frame 3, and the support tube is arranged through the damping shell 41, the damping inner shell 44 is fixedly connected to the support rod 43, and the sliding sleeve is arranged inside the damping shell 41, and the outer wall of the damping inner shell 44 is abutted against the inner wall of the damping shell 41, and the bottom of the damping shell 41 penetrates the connecting plate 14 and the sliding plate 16 and is provided with a damping hole 45. When the high-pressure aluminum bar moves to above the fixed frame 2 or the sliding frame 3, the damping inner shell 44 and the support rod 43 move downward under the action of gravity. Since the outer wall of the damping inner shell 44 abuts against the inner wall of the damping shell 41, the gas inside the damping shell 41 cannot be discharged directly. At this time, the gas inside the damping shell 41 is discharged from the damping hole 45, causing the fixed frame 2 or the sliding frame 3 to move slowly downward. After the high-pressure aluminum bar is taken out, the damping inner shell 44 is reset under the push of the support spring 42, so that the first clamping platform 21 and the third clamping platform 31 move to the position above the straightening roller 11.

[0038] like Figure 5 , Figure 6 and Figure 7As shown, the synchronization mechanism 5 includes a take-up drum 51, a synchronization line 52, a rotating gear 53, a limit rack 54, a reset spring 55, a connecting groove 56, a trigger block 57, a limit pin 58, a limit spring 59, a fixed groove 6, a sliding pin 61 and a sliding spring 62. The take-up drum 51 is fixedly connected to the side wall of the third clamping roller 32, the synchronization line 52 is fixedly connected to the take-up drum 51 and penetrates the fourth clamping platform 33 and extends into the sliding plate 16, the rotating gear 53 is fixedly connected to the side wall of the fourth clamping roller 34, the limit rack 54 is slidably connected to the fourth clamping platform 33 and is arranged at a lower position of the rotating gear 53, the reset spring 55 is fixedly connected to the lower position of the limit rack 54, and one end of the reset spring 55 is fixedly connected to the fourth clamping platform 33, and the connection The connecting groove 56 penetrates the fourth clamping platform 33, the trigger block 57 is fixedly connected to the synchronization line 52 and is arranged at the lower position of the fourth clamping platform 33, the limit pin 58 is slidably connected to the fourth clamping platform 33, the limit spring 59 is fixedly connected to the limit pin 58, and one end of the limit spring 59 is fixedly connected to the fourth clamping platform 33, the limit spring 59 can push the limit pin 58 to move toward the limit rack 54, the fixed groove 6 is opened on the material receiving frame 13, and is arranged on the side wall of the sliding groove 15, the sliding pin 61 is slidably connected to the sliding plate 16, the sliding spring 62 is fixedly connected to the sliding pin 61, one end of the sliding spring 62 is fixedly connected to the sliding plate 16, and the sliding spring 62 is used to push the sliding pin 61 to move toward one side of the fixed groove 6.

[0039] When the high-pressure aluminum row moves out from the middle position of the first clamping roller 22 and the second clamping roller 24, the third clamping roller 32 abuts against the top side wall of the high-pressure aluminum row. At this time, the sliding frame 3 is in a fixed state under the restriction of the sliding pin 61, and the third clamping roller 32 rotates. At this time, the fourth clamping roller 34 abuts against the bottom side wall of the high-pressure aluminum row, and the fourth clamping roller 34 rotates. The rotation of the third clamping roller 32 drives the take-up drum 51 to rotate, and the rotation of the take-up drum 51 causes the synchronous line 52 to move upward. When the synchronous line 52 moves up to the limit pin 58, the trigger block 57 pushes the limit pin 58 to move The limit pin 58 moves toward the side away from the limit rack 54, so that the limit pin 58 releases the restriction on the limit rack 54. The limit rack 54 moves upward under the push of the reset spring 55, so that the limit rack 54 and the rotating gear 53 are engaged. After the limit rack 54 and the rotating gear 53 are engaged, the fourth clamping roller 34 stops rotating and drives the sliding pin 61 to move during the upward movement of the synchronization line 52, so that the sliding pin 61 moves out of the fixed groove 6. Since the high-pressure aluminum bar is in a moving state at this time, the sliding plate 16 drives the sliding frame 3 to move synchronously with the high-pressure aluminum bar.

[0040] When the present application is in use, the aluminum bar raw material is first transported to the straightening machine 1 through the feeding platform 12, and after being straightened by the straightening roller 11, it is moved toward the receiving rack 13. When the high-pressure aluminum bar is straightened by the straightening roller 11 on the straightening machine 1 and extended, the second clamping roller 24 abuts against the bottom side of the high-pressure aluminum bar, and the first clamping roller 22 abuts against the top side of the high-pressure aluminum bar. During the movement of the high-pressure aluminum bar, the first clamping roller 22 and the second clamping roller 24 rotate synchronously. During this process, the second clamping roller 24 is always pushed by the moving spring 46 to maintain an upward state, so that the first clamping roller 22 and the second clamping roller 24 always remain in a clamped state during this process.

[0041] When the high-pressure aluminum bar moves out from the middle position between the first clamping roller 22 and the second clamping roller 24, the third clamping roller 32 abuts against the top side of the high-pressure aluminum bar, and the fourth clamping roller 34 is always pushed by the moving spring 46 to maintain an upward state during this process, so that the third clamping roller 32 and the fourth clamping roller 34 always remain in a clamped state during this process.

[0042] When the high-pressure aluminum bar moves to above the fixed frame 2 or the sliding frame 3, the damping inner shell 44 and the support rod 43 move downward under the action of gravity. Since the outer wall of the damping inner shell 44 abuts against the inner wall of the damping shell 41, the gas inside the damping shell 41 cannot be discharged directly. At this time, the gas inside the damping shell 41 is discharged from the damping hole 45, causing the fixed frame 2 or the sliding frame 3 to move slowly downward. After the high-pressure aluminum bar is taken out, the damping inner shell 44 is reset under the push of the support spring 42, so that the first clamping platform 21 and the third clamping platform 31 move to the position above the straightening roller 11.

[0043] When the high-pressure aluminum row moves out from the middle position of the first clamping roller 22 and the second clamping roller 24, the third clamping roller 32 abuts against the top side wall of the high-pressure aluminum row. At this time, the sliding frame 3 is in a fixed state under the restriction of the sliding pin 61, and the third clamping roller 32 rotates. At this time, the fourth clamping roller 34 abuts against the bottom side wall of the high-pressure aluminum row, and the fourth clamping roller 34 rotates. The rotation of the third clamping roller 32 drives the take-up drum 51 to rotate, and the rotation of the take-up drum 51 causes the synchronous line 52 to move upward. When the synchronous line 52 moves up to the limit pin 58, the trigger block 57 pushes the limit pin 58 to move The limit pin 58 moves toward the side away from the limit rack 54, so that the limit pin 58 releases the restriction on the limit rack 54. The limit rack 54 moves upward under the push of the reset spring 55, so that the limit rack 54 and the rotating gear 53 are engaged. After the limit rack 54 and the rotating gear 53 are engaged, the fourth clamping roller 34 stops rotating and drives the sliding pin 61 to move during the upward movement of the synchronization line 52, so that the sliding pin 61 moves out of the fixed groove 6. Since the high-pressure aluminum bar is in a moving state at this time, the sliding plate 16 drives the sliding frame 3 to move synchronously with the high-pressure aluminum bar.

[0044] In this embodiment, by supporting the movable spring 46, the first clamping mechanism and the second clamping mechanism can provide certain support to the straightened aluminum bar. When the straightened aluminum bar is extended longer, the load of the aluminum bar on the straightening roller 11 can be reduced, thereby improving the straightening quality.

[0045] In this embodiment, when the aluminum bar is being conveyed, the second clamping roller 24 and the fourth clamping roller 34 are pressed down by using the weight of the aluminum bar itself, and under the push of the movable spring 46, the first clamping roller 22, the second clamping roller 24, the third clamping roller 32 and the fourth clamping roller 34 can exert a certain supporting force on the aluminum bar, thereby reducing the deformation of the aluminum bar caused by its own gravity when the aluminum bar is extended too long, thereby improving the straightening quality.

[0046] In this embodiment, due to the setting of the sliding frame 3, in the process of straightening aluminum bars of different lengths, the movement degree of the sliding frame 3 can be adjusted according to the length of the aluminum bars, thereby improving the adaptability of the straightening machine 1. In addition, since there is no need to set up a separate straightening machine 1 for each length of aluminum bars, the time for adjusting the equipment is reduced and the probability of downtime is reduced.

[0047] In this embodiment, by supporting both ends of the aluminum bar, the secondary deformation of the aluminum bar can be reduced. At the same time, due to the setting of the synchronization mechanism 5, the bending or shaking caused by the gravity of the aluminum bar itself can be reduced during the extension process, and the straightening direction and position of the aluminum bar can be maintained, thereby improving the straightening accuracy. In this process, the staff only needs to observe the height limits of the first clamping platform 21 and the third clamping platform 31 to determine whether the aluminum bar is straightened.

[0048] The implementation principle of a high-voltage aluminum bar straightening device for new energy vehicles in the embodiment of the present application is:

[0049] First, the aluminum bar raw material is transported to the straightening machine 1 through the feeding platform 12, and after being straightened by the straightening roller 11, it moves toward the receiving rack 13. When the high-pressure aluminum bar is straightened by the straightening roller 11 on the straightening machine 1 and then extended, the second clamping roller 24 abuts against the bottom side of the high-pressure aluminum bar, and the first clamping roller 22 abuts against the top side of the high-pressure aluminum bar. During the movement of the high-pressure aluminum bar, the first clamping roller 22 and the second clamping roller 24 rotate synchronously. During this process, the second clamping roller 24 is always pushed by the moving spring 46 to maintain an upward state, so that the first clamping roller 22 and the second clamping roller 24 always remain in a clamped state during this process.

[0050] When the high-pressure aluminum bar moves out from the middle position between the first clamping roller 22 and the second clamping roller 24, the third clamping roller 32 abuts against the top side of the high-pressure aluminum bar, and the fourth clamping roller 34 is always pushed by the moving spring 46 to maintain an upward state during this process, so that the third clamping roller 32 and the fourth clamping roller 34 always remain in a clamped state during this process.

[0051] When the high-pressure aluminum bar moves to above the fixed frame 2 or the sliding frame 3, the damping inner shell 44 and the support rod 43 move downward under the action of gravity. Since the outer wall of the damping inner shell 44 abuts against the inner wall of the damping shell 41, the gas inside the damping shell 41 cannot be discharged directly. At this time, the gas inside the damping shell 41 is discharged from the damping hole 45, causing the fixed frame 2 or the sliding frame 3 to move slowly downward. After the high-pressure aluminum bar is taken out, the damping inner shell 44 is reset under the push of the support spring 42, so that the first clamping platform 21 and the third clamping platform 31 move to the position above the straightening roller 11.

[0052] When the high-pressure aluminum row moves out from the middle position of the first clamping roller 22 and the second clamping roller 24, the third clamping roller 32 abuts against the top side wall of the high-pressure aluminum row. At this time, the sliding frame 3 is in a fixed state under the restriction of the sliding pin 61, and the third clamping roller 32 rotates. At this time, the fourth clamping roller 34 abuts against the bottom side wall of the high-pressure aluminum row, and the fourth clamping roller 34 rotates. The rotation of the third clamping roller 32 drives the take-up drum 51 to rotate, and the rotation of the take-up drum 51 causes the synchronous line 52 to move upward. When the synchronous line 52 moves up to the limit pin 58, the trigger block 57 pushes the limit pin 58 to move The limit pin 58 moves toward the side away from the limit rack 54, so that the limit pin 58 releases the restriction on the limit rack 54. The limit rack 54 moves upward under the push of the reset spring 55, so that the limit rack 54 and the rotating gear 53 are engaged. After the limit rack 54 and the rotating gear 53 are engaged, the fourth clamping roller 34 stops rotating and drives the sliding pin 61 to move during the upward movement of the synchronization line 52, so that the sliding pin 61 moves out of the fixed groove 6. Since the high-pressure aluminum bar is in a moving state at this time, the sliding plate 16 drives the sliding frame 3 to move synchronously with the high-pressure aluminum bar.

[0053] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0054] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
