Description

Technical Field

[0001] This invention relates to the field of heat dissipation pipe bending device technology, and in particular to a deformation-resistant bending device and method for heat dissipation pipes in new energy vehicles. Background Technology

[0002] The cooling pipes of new energy vehicles are usually made of aluminum alloy or engineering plastics. During bending, they mainly face the problem of deformation. When the pipes are subjected to external bending forces, because the inside is hollow and the pipe walls lack support, the cross-section is prone to collapse (from a circle to an ellipse) or wrinkling on the inside. Therefore, the core requirement of the anti-deformation bending device is to provide effective and uniform support for the pipes during the bending process, prevent any unacceptable deformation of its cross-section, and ensure that the inner wall is smooth and fluid after bending, with optimal hydraulic characteristics.

[0003] Existing bending devices use fixed clamps to bend rectangular heat dissipation pipes based on their dimensions. This requires changing the clamps when bending heat dissipation pipes of different sizes, increasing both the cost and efficiency of bending the pipes. Summary of the Invention

[0014] A method for using a deformation-resistant bending device for a heat dissipation pipe in a new energy vehicle, based on the aforementioned deformation-resistant bending device for a heat dissipation pipe in a new energy vehicle, specifically includes the following steps:

[0015] S1: Place the heat dissipation pipe between the first and second shielding plates. The control of the squeezing block by the squeezing push rod moves so that the squeezing block squeezes the second heat dissipation pipe from bottom to top. Then the third push rod controls the movement of the barrier plate so that the barrier plate separates from the bottom heat dissipation pipe and the bottom heat dissipation pipe falls onto the fixed transfer plate.

[0016] S2: The transfer frame compresses the spring, the transfer frame moves downward, and then the fourth push rod controls the sliding transfer plate to move and catch the heat dissipation pipe. Then the above process is repeated so that the heat dissipation pipe falls on the sliding transfer plate.

[0017] S3: The increased weight on the transfer frame causes the limit bar to move downward. The limit bar is deformed by the compression of the fixed bracket and is blocked by the blocking block to maintain the deformed state. The slide table of the third electric slide rail drives the transfer frame to move. The limit bar separates from the blocking block and returns to its original state. The fixed transfer plate and the sliding transfer plate drive the heat dissipation pipe to move between the corresponding third clamping part and the fourth clamping part.

[0018] S4: The second push rod controls the second clamping component to clamp the heat dissipation pipe. Then, the slide table of the third electric slide rail drives the fixed transfer plate and the sliding transfer plate to move. The lower part of the limit bar hooks onto the fixed bracket. During the movement, the limit bar is blocked by the blocking block, thereby releasing the limit on the fixed bracket. Then, the transfer frame moves upward under the action of the spring and returns to its original position.

[0019] S5: The second electric slide rail drives the heat dissipation pipe to move between the first clamping part and the second clamping part. Then the first push rod controls the first clamping member to clamp the pipe. After that, the heat dissipation pipe is bent under the combined action of the clamping assembly and the auxiliary assembly.

[0020] S6: When changing direction, the clamping component and auxiliary component move away from the heat dissipation pipe. Then, the position of the heat dissipation pipe is adjusted by the first electric slide rail and the second electric slide rail. After that, the motor drives the sliding component to rotate 180°, and then the heat dissipation pipe returns to the space between the first clamping part and the second clamping part, thereby bending the heat dissipation pipe in another direction. The above process is repeated several times until the bending of the heat dissipation pipe is completed.

[0021] The present invention has the following advantages: The present invention controls the first clamping member and the second clamping member respectively by the first push rod and the second push rod, so that the relative positions of the first clamping member and the bending member, as well as the second clamping member and the fixing member, can be changed as needed, thereby adapting to heat dissipation pipes of different sizes, so as to perform bending processing on heat dissipation pipes of different sizes.

[0022] The heat dissipation pipes are transferred by a transfer frame and its fixed and sliding transfer plates, thereby realizing automatic feeding of the heat dissipation pipes and improving the efficiency of the device in bending the heat dissipation pipes.

[0023] By simultaneously extending the telescopic ends of the fifth and sixth push rods, the inclined heat dissipation pipes are laid flat, making it easier to bend them. Attached Figure Description

Detailed Implementation

[0030] The technical solution will be further explained below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to the components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning.

[0031] Example 1

[0032] When bending heat dissipation pipes, existing devices use clamps of fixed sizes. This means that the clamps need to be replaced when bending heat dissipation pipes of different sizes, which not only increases the cost of bending heat dissipation pipes, but also affects the efficiency of bending heat dissipation pipes.

[0033] A device for preventing deformation and bending of heat dissipation pipes in new energy vehicles, such as Figures 1-4 As shown, the device includes a frame 1, a bending assembly 2 on the front side of the frame 1, a bending component 201 fixedly connected to the bending assembly 2, and the bending assembly 2 being an existing device capable of rotating the bending component 201 to bend the heat dissipation pipe. A first clamping component 3 is slidably connected to the bending component 201. A first push rod 4 is fixedly connected to the bending assembly 2, and the telescopic end of the first push rod 4 is fixedly connected to the first clamping component 3. The bending assembly 2 is also equipped with a clamping assembly 5, which is an existing device used to hold the heat dissipation pipe in place, causing it to bend with the bending component 201. An auxiliary assembly 6, also an existing device, is provided on the frame 1 to hold the side of the heat dissipation pipe, ensuring the heat dissipation pipe is tightly against the bending component 201. Both the clamping assembly 5 and the auxiliary assembly 6 provide more comprehensive protection for the bending of the heat dissipation pipe, thereby preventing unacceptable deformation during the bending process. A first electric slide rail 7 is fixedly connected to the frame 1, and a second electric slide rail 8 is fixedly connected to the slide of the first electric slide rail 7. The slide table of the second electric slide rail 8 is fixedly connected to a hydraulic rod 9. The hydraulic rod 9 is used to adjust the height of the heat dissipation pipe so that the height of the heat dissipation pipe after rotating 180° is equal to the original height. The telescopic end of the hydraulic rod 9 is fixedly connected to a connector 10. The connector 10 is fixedly connected to a fixed rail 11. The fixed rail 11 is slidably connected to a sliding member 12. Both the sliding member 12 and the fixed rail 11 are arc-shaped and have a superior arc, so that the sliding member 12 can rotate 180° along the fixed rail 11. The sliding member 12 is fixedly connected to a fixing member 13. The fixing member 13 is slidably connected to a second clamping member 14. The fixing member 13 and the second clamping member 14 are used to clamp the heat dissipation pipe, thereby supplying the heat dissipation pipe forward and bending the heat dissipation pipe multiple times. The fixing member 13 is fixedly connected to a second push rod 15. The telescopic end of the second push rod 15 is fixedly connected to the second clamping member 14. The fixed rail 11 is fixedly connected to a motor 16. The output shaft of the motor 16 is transmitted to the sliding member 12 through a gear and a toothed gear.

[0034] When using this device to bend the heat dissipation pipe, first place the pipe to be bent on the fixing member 13, then the second push rod 15 is activated, the telescopic end of the second push rod 15 retracts, the telescopic end of the second push rod 15 drives the second clamping member 14 to move downward, the second clamping member 14 moves downward and clamps the heat dissipation pipe with the fixing member 13, then the slide of the second electric slide rail 8 drives the hydraulic rod 9 to move forward, the hydraulic rod 9 drives the connecting member 10 to move, the connecting member 10 drives the fixed rail 11 to move, the fixed rail 11 drives the sliding member 12 to move, the sliding member 12 drives the fixing member 13 to move, the fixing member 13 drives the heat dissipation pipe to move, when the heat dissipation pipe moves between the bending member 201 and the clamping member 3 and stops moving, then the telescopic end of the first push rod 4 retracts and drives the first clamping member 3 to move, so that the bending member 201 and the clamping member 3 clamp the pipe, at the same time the clamping assembly 5 and the auxiliary assembly 6 are activated to clamp the heat dissipation pipe, then the bending assembly 2 drives the first clamping member 3 and the clamping assembly 5 to rotate, bending the heat dissipation pipe.

[0035] When changing the bending direction of the heat dissipation pipe, the clamping component 5 and the auxiliary component 6 move away from the heat dissipation pipe. The first push rod 4 controls the first clamping member 3 to move upward, releasing the clamp on the heat dissipation pipe. Then, the second electric slide rail 8 drives the heat dissipation pipe to move forward. Then, the slide table of the first electric slide rail 7 drives the second electric slide rail 8 to move to the right. The second electric slide rail 8 drives the heat dissipation pipe to move to the right. Then, the output shaft of the motor 16 drives the sliding member 12 to rotate 180° through the gear with missing teeth. The first electric slide rail 7 and the second electric slide rail 8 together drive the heat dissipation pipe back between the first clamping part 202 and the second clamping part 301, thereby bending the heat dissipation pipe in another direction. The above process is repeated several times until the bending of the heat dissipation pipe is completed.

[0036] Example 2

[0037] The existing device can only bend one heat dissipation pipe at a time when bending the heat dissipation pipe, and it cannot automatically add a new heat dissipation pipe after the previous heat dissipation pipe is bent, which affects the efficiency of bending the heat dissipation pipe.

[0038] Based on Example 1, such as Figure 2 As shown, the bending member 201, the first clamping member 3, the fixing member 13, and the second clamping member 14 are respectively provided with a first clamping part 202, a second clamping part 301, a third clamping part 1301, and a fourth clamping part 1401. The first clamping part 202, the second clamping part 301, the third clamping part 1301, and the fourth clamping part 1401 are all multiple and equal in number, so that multiple heat dissipation pipes can be bent at the same time, thereby improving the efficiency of the device in bending heat dissipation pipes.

[0039] like Figure 1 and Figure 3 As shown, the frame 1 is fixedly connected to two first supports 17 and two second supports 18. The first supports 17 and the second supports 18 are respectively fixedly connected to a first baffle plate 19 and a second baffle plate 20. The first baffle plate 19 is slidably connected to a barrier plate 21. The first baffle plate 19 and the second baffle plate 20 are used to limit the heat dissipation pipes so that the heat dissipation pipes to be bent are stacked together. The barrier plate 21 is used to block the heat dissipation pipes so that the heat dissipation pipes will not fall. The first supports 17 are fixedly connected to a fourth support 1701. The fourth support 1701 is fixedly connected to a third push rod 22. The telescopic end of the third push rod 22 is fixedly connected to the barrier plate 21.

[0040] like Figure 3 and Figure 5As shown, the fourth bracket 1701 is fixedly connected to a pressing push rod 2201, and the telescopic end of the pressing push rod 2201 is fixedly connected to a pressing block 2202. The pressing block 2202 is used to press the heat dissipation pipe. The vertical distance between the pressing block 2202 and the baffle plate 21 is between the thickness of one heat dissipation pipe and the thickness of two heat dissipation pipes, so that the pressing block 2202 can press the second heat dissipation pipe from bottom to top, so that the heat dissipation pipe and the pipe above it are stopped at the current position, and then the bottommost heat dissipation pipe falls down.

[0041] like Figure 3 and Figure 5 As shown, the frame 1 is fixedly connected to a third electric slide rail 23, the slide table of the third electric slide rail 23 is fixedly connected to a fixed bracket 24, the fixed bracket 24 is slidably connected to a transfer frame 25, the transfer frame 25 is fixedly connected to a set of fixed transfer plates 26, each set of fixed transfer plates 26 has two fixed transfer plates 26, front and rear, the fixed transfer plates 26 are located below the barrier plate 21, thereby transferring the heat dissipation pipe.

[0042] like Figure 3 and Figure 5 As shown, the transfer frame 25 is slidably connected with two sets of upper and lower sliding transfer plates 27. Each set of sliding transfer plates 27 has two sliding transfer plates 27, one in front and one in back. The sum of the number of sets of sliding transfer plates 27 and the number of sets of fixed transfer plates 26 is equal to the number of the first clamping parts 202. The sliding transfer plates 27 are fixedly connected to connecting rods 28. The transfer frame 25 is fixedly connected to two fourth push rods 29. The number of fourth push rods 29 is equal to the number of sets of sliding transfer plates 27. The telescopic end of the fourth push rod 29 is fixedly connected to the adjacent connecting rod 28. A spring 30 is provided between the fixed bracket 24 and the transfer frame 25. In the vertical direction, the fixed transfer plate 26 and several sliding transfer plates 27 are evenly distributed at intervals. The interval between the fixed transfer plate 26 and adjacent sliding transfer plates 27, and between two adjacent sliding transfer plates 27 in different groups of sliding transfer plates 27, is d. The weight of the heat dissipation pipe is G, and the elastic coefficient of the spring 30 is k=G / d. Thus, when the heat dissipation pipe falls on the fixed transfer plate 26, the spring 30 generates a compression of d, causing the lower sliding transfer plate 27 to move to the original height of the fixed transfer plate 26. Damping is provided between the fixed bracket 24 and the transfer frame 25 to reduce the up-and-down shaking of the spring 30 due to inertia when the heat dissipation pipe falls on the fixed transfer plate 26.

[0043] like Figure 3 and Figure 5As shown, the transfer frame 25 is fixedly connected to a limiting strip 2501, which limits the movement of the transfer frame 25 to the fixed bracket 24. The limiting strip 2501 is made of elastic material, so that the lower part of the limiting strip 2501 hooks onto the fixed bracket 24 to lock the transfer frame 25. The frame body 1 is fixedly connected to a blocking block 2502, which presses against the limiting strip 2501. As the lower part of the limiting strip 2501 hooks onto the fixed bracket 24 and moves to the left, the limiting strip 2501 is blocked by the blocking block 2502, causing the limiting strip 2501 to separate from the fixed bracket 24, thereby allowing the transfer frame 25 to return to its original position.

[0044] Before bending the heat dissipation pipes, the heat dissipation pipes are neatly arranged between the first baffle plate 19 and the second baffle plate 20. Once the space between them is full, the telescopic end of the pressing push rod 2201 extends, causing the pressing block 2202 to move and press the second heat dissipation pipe from bottom to top. Then, the telescopic end of the third push rod 22 retracts, causing the blocking plate 21 to move, separating it from the bottommost heat dissipation pipe and allowing it to fall onto the fixed transfer plate 26. Afterward, the telescopic end of the third push rod 22 drives the blocking plate 21 to return to its original position. At this time, the telescopic end of the pressing push rod 2201 drives the pressing block 2202 to return to its original position. When the heat dissipation pipe... After landing on the fixed transfer plate 26, the weight on the transfer frame 25 increases, compressing the spring 30. The transfer frame 25 moves downward until the horizontal height of the lower sliding transfer plate 27 matches the original horizontal height of the fixed transfer plate 26. Then, the telescopic end of the lower fourth push rod 29 extends, pushing the sliding transfer plate 27 to move below the heat dissipation pipe to catch the falling heat dissipation pipe. The above process is repeated to allow the heat dissipation pipe to land on the sliding transfer plate 27. When all the sliding transfer plates 27 are loaded with heat dissipation pipes, the transfer frame 25 drives the limiting strip 2501 to move downward. The limiting strip 2501 is deformed by the compression of the fixed bracket 24. When the limiting strip 2501... After the lower part passes the lower side of the fixed bracket 24, the limiting strip 2501 is blocked by the blocking block 2502. The slide of the third electric slide rail 23 drives the fixed bracket 24 to move to the right. The fixed bracket 24 drives the transfer frame 25 to move. The transfer frame 25 drives the limiting strip 2501, the fixed transfer plate 26 and all the sliding transfer plates 27 to move. The limiting strip 2501 separates from the blocking block 2502. After the limiting strip 2501 loses its compression, it returns to its original shape under its own elasticity. The fixed transfer plate 26 and the sliding transfer plate 27 drive the heat dissipation pipe to move until the heat dissipation pipe moves between the corresponding third clamping part 1301 and the fourth clamping part 1401. The telescopic end of the second push rod 15 retracts and drives The second clamping member 14 moves downward, thereby clamping the heat dissipation pipe with the second clamping member 14 and the fixing member 13. Then, the slide of the third electric slide rail 23 moves to the left. After the heat dissipation pipe on the fixed transfer plate 26 and the sliding transfer plate 27 is transferred away, the weight on the transfer frame 25 decreases. The transfer frame 25 moves upward under the action of the spring 30. However, because the lower part of the limiting strip 2501 hooks the fixed bracket 24, the transfer frame 25 stops moving. Before the fixed bracket 24 returns to its original position, the limiting strip 2501 contacts the blocking block 2502, causing the limiting strip 2501 to deform and release the limitation on the fixed bracket 24. Then, the transfer frame 25 moves upward under the action of the spring 30 and returns to its original position.

[0045] Example 3

[0046] Based on Example 2, such as Figure 3 and Figure 5 As shown, a hopper can be provided on the upper side of the first baffle plate 19 and the second baffle plate 20 to store more heat dissipation pipes. When the number of heat dissipation pipes between the first baffle plate 19 and the second baffle plate 20 decreases, the heat dissipation pipes in the hopper fall into the space between the first baffle plate 19 and the second baffle plate 20 to replenish them. The fourth bracket 1701 is fixedly connected to the fifth push rod 31, the second bracket 18 is fixedly connected to the fifth bracket 1801, and the fifth bracket 1801 is fixedly connected to the sixth push rod 32. The fifth push rod 31 and the sixth push rod 32 are used to flatten the inclined heat dissipation pipes so that the heat dissipation pipes can be bent. The fifth push rod 31 and the sixth push rod 32 are opposite each other and staggered vertically. The vertical distance between the fifth push rod 31 and the sixth push rod 32 is greater than the thickness of the heat dissipation pipe and less than the width of the heat dissipation pipe, so that the heat dissipation pipe can be pushed flat from the inclined state by the fifth push rod 31 and the sixth push rod 32. A visual sensor can be set on the first shielding plate 19 or the second shielding plate 20 to monitor whether the heat dissipation pipe between the first shielding plate 19 and the second shielding plate 20 is in a horizontal state. If the heat dissipation pipe is inclined, the fifth push rod 31 and the sixth push rod 32 are activated to adjust the heat dissipation pipe to a horizontal state.

[0047] Example 4

[0048] A method for using a deformation-resistant and bending-resistant device for heat dissipation pipes in new energy vehicles, based on Example 3, such as... Figures 1-5 As shown, the above-mentioned anti-deformation and anti-bending device for heat dissipation pipes in new energy vehicles specifically includes the following steps:

[0049] S1: Place the heat dissipation pipe between the first baffle plate 19 and the second baffle plate 20. The control of the pressing block 2202 of the pressing push rod 2201 moves, so that the pressing block 2202 presses the second heat dissipation pipe from bottom to top. Then the third push rod 22 controls the movement of the barrier plate 21, so that the barrier plate 21 separates from the bottom heat dissipation pipe, and the bottom heat dissipation pipe falls onto the fixed transfer plate 26.

[0050] S2: The transfer frame 25 compresses the spring 30, the transfer frame 25 moves downward, and then the fourth push rod 29 controls the sliding transfer plate 27 to move and catch the heat dissipation pipe. Then the above process is repeated so that the heat dissipation pipe falls on the sliding transfer plate 27.

[0051] S3: The increased weight on the transfer frame 25 causes the limiting strip 2501 to move downward. The limiting strip 2501 is deformed by the compression of the fixed bracket 24 and is blocked by the blocking block 2502 to maintain the deformed state. The slide table of the third electric slide rail 23 drives the transfer frame 25 to move. The limiting strip 2501 separates from the blocking block 2502 and returns to its original state. The fixed transfer plate 26 and the sliding transfer plate 27 drive the heat dissipation pipe to move between the corresponding third clamping part 1301 and fourth clamping part 1401.

[0052] S4: The second push rod 15 controls the second clamping member 14 to clamp the heat dissipation pipe. Then, the slide table of the third electric slide rail 23 drives the fixed transfer plate 26 and the sliding transfer plate 27 to move. The lower part of the limit bar 2501 hooks the fixed bracket 24. During the movement, the limit bar 2501 is blocked by the blocking block 2502, thereby releasing the limit on the fixed bracket 24. Then, the transfer frame 25 moves upward under the action of the spring 30 and returns to its original position.

[0053] S5: The second electric slide rail 8 drives the heat dissipation pipe to move between the first clamping part 202 and the second clamping part 301. Then the first push rod 4 controls the first clamping member 3 to clamp the pipe. After that, the heat dissipation pipe is bent under the joint action of the clamping component 5 and the auxiliary component 6.

[0054] S6: When changing direction, the clamping component 5 and the auxiliary component 6 move away from the heat dissipation pipe. Then, the position of the heat dissipation pipe is adjusted by the first electric slide rail 7 and the second electric slide rail 8. After that, the motor 16 drives the sliding component 12 to rotate 180°, and then the heat dissipation pipe returns to the space between the first clamping part 202 and the second clamping part 301, thereby bending the heat dissipation pipe in another direction. The above process is repeated several times until the bending of the heat dissipation pipe is completed.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
