Description

Technical Field

[0001] This invention belongs to the field of heat pipe rolling technology, specifically relating to a PTC heating core heat pipe rolling device. Background Technology

[0002] The purpose of rolling the heat pipe of PTC's heating core is to reduce the gap between the heat pipe and the heating core, so that the inner wall of the heat pipe is firmly attached to the heating core, thereby increasing the contact area between the heating core and the heat pipe and thus improving its conduction efficiency.

[0003] Generally, heat pipes are made of aluminum, and they are usually processed by cold rolling to avoid surface roughness or grain coarsening caused by high-temperature oxidation, ensuring the precision of the fit between the pipe wall and the heating core. However, during the rolling process, because the outer wall of the heat pipe is bonded to the outside of the rolling roller, the side wall of the heat pipe is prone to concave phenomenon, i.e., roll folding. The pipe wall has longitudinal wrinkles that are concave on the outside and convex on the inside, forming strip-shaped depressions on the outer surface. This can easily cause cracks in the protruding parts inside the heat pipe, thus affecting the service life of the heat pipe. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to provide a PTC heating core heat pipe rolling device, which can solve the problem of longitudinal wrinkles on the tube wall with concave exterior and convex interior, forming strip-shaped depressions on the outer surface, which easily leads to cracks in the protruding parts inside the heat pipe.

[0005] To solve the above problems, the present invention provides a rolling device for the heating core heat pipe of PTC, comprising: a bottom support with a conveying groove on its top, a circulation unit arranged in the conveying groove, an upper support connected to the top of the bottom support, and a rolling mechanism arranged in the upper support. The support input mechanism is located at the end of the upper support and is used to support the inside of the heat pipe before it is fed into the rolling mechanism. The support input mechanism also includes an inner support assembly for supporting the inside of the heat pipe. A separation mechanism, located at the end of the upper support away from the support input mechanism, is used to release the internal support of the heat pipe. The lowering mechanism, located below the separation mechanism, is used to transport the inner support assembly into the circulation unit; An installation mechanism, located below the support input mechanism, is used to transport the inner support component into the support input mechanism.

[0006] Furthermore, the support input mechanism includes an input plate connected to the end of the upper support. The top of the input plate has a wide groove, and the bottom side wall of the wide groove has a through groove. Input wheels are rotatably connected to the two opposite side walls of the wide groove. A first motor is fixedly connected to the bottom side of the input plate, and the output end of the first motor is connected to the corresponding input wheel.

[0007] Furthermore, the inner support assembly includes an inner support column disposed in the through groove, the end of the inner support column away from the upper support being tapered, and a blocking assembly being disposed on the side of the input plate near the upper support.

[0008] Furthermore, the barrier assembly includes a notch, which is formed on the side of the wide slot near the upper support. A torsion spring is connected to the top sidewall of the notch, and a barrier shaft is connected to the bottom end of the torsion spring. A barrier plate for blocking the inner support column is connected to the outer periphery of the barrier shaft.

[0009] Furthermore, the separation mechanism includes an output plate, which is connected to the end of the upper support away from the input plate. An output groove is provided on the top side of the output plate, and output wheels are rotatably connected to the two inner sidewalls opposite to each other of the output groove. A second motor is connected to the bottom side of the output plate, and the output end of the second motor is connected to the corresponding output wheel. Two slides are provided on the side of the output plate near the upper support. Separation plates are slidably connected in both slides. Separation springs are connected between the separation plates and the inner sidewalls of the slides. The two separation plates are inclined on the side that is close to each other.

[0010] Furthermore, the lowering mechanism includes a lowering groove, which is opened on the bottom side wall of the output groove. Two guide plates are connected to the bottom of the output plate, and a lowering plate is connected between the two guide plates. The end of the lowering plate is inclined downward and extends into the conveying groove. A number of rotating rods are rotatably connected to the top side wall of the lowering plate. A slot for avoiding the inner support column is opened on the bottom side wall of the upper support at one end of the output plate.

[0011] Furthermore, the circulation unit includes a bottom trough, which is opened on the bottom side wall of the conveying trough. Two ends of the inner side wall of the bottom trough are rotatably connected to a rotating shaft, and a conveyor belt is sleeved on both rotating shafts. A third motor is connected to the side of the bottom support, and the output end of the third motor is connected to the corresponding rotating shaft.

[0012] Furthermore, the mounting mechanism includes a hydraulic telescopic rod, which is fixedly installed at the bottom of the bottom support. The telescopic end of the hydraulic telescopic rod extends to the bottom of the through groove and is connected to a support plate, and is in contact with the inner support column. A clearance groove for avoiding the support plate is provided on the top side of the bottom support at the position of the hydraulic telescopic rod. Two limiting plates are fixedly connected to the bottom of the input plate.

[0013] Furthermore, a support spring is connected to the side of the bottom groove near the mounting mechanism, and a blocking block is connected to the top of the support spring. The blocking block is located below the tray.

[0014] Furthermore, the inner support column has a circular groove on one end away from the upper support and on both opposite sides, and a universal ball is rotatably connected in the circular groove. Beneficial effects

[0015] 1. The PTC heating core heat pipe rolling device can utilize the cooperation of the support input mechanism and the inner support component to automatically insert an inner support column into the heat pipe during rolling. The inner support column supports the two opposite side walls of the heat pipe, preventing wrinkles that are concave on the outside and convex on the inside from forming during the rolling process, which would cause cracks in the protruding part of the heat pipe and reduce its lifespan. 2. A PTC heating core heat conduction tube rolling device, wherein the heat conduction tube is conveyed from the conveying mechanism to the wide groove on the input plate. The width of the groove is smaller than the width of the heat conduction tube. When the end of the heat conduction tube moves into the wide groove, it will be fitted onto the inner support assembly, and the outer wall will also be in contact with the input wheel. Then, the input wheel is driven by the first motor to rotate, thereby driving the heat conduction tube to move, so that the inner support assembly is completely inside the heat conduction tube, thereby supporting the inner wall of the heat conduction tube. 3. In this PTC heating core heat pipe rolling device, the blocking plate in the blocking assembly blocks the movement of the inner support column, allowing the inner support column to be fully inserted into the heat pipe. When the heat pipe moves to the blocking plate, the force of the heat pipe pushing the blocking plate is greater than the force required for the torsion spring to twist. Subsequently, the blocking plate drives the rotation of the blocking shaft, which in turn drives the torsion spring to twist. After the blocking plate is opened, the heat pipe can leave the wide slot and move into the rolling mechanism for rolling. After the heat pipe is fully inserted into the rolling mechanism, the next heat pipe can enter the wide slot, while the next inner support column will be conveyed into the through slot.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See also Figures 1-8 As shown, according to Embodiment 1 of the present invention, a rolling device for the heating core heat conduction tube of a PTC is provided, comprising: a bottom support 1, a conveying groove 2 is provided on its top, a circulation unit 3 is provided in the conveying groove 2, an upper support 4 is connected to the top of the bottom support 1, and a rolling mechanism 5 is provided in the upper support 4. The support input mechanism 6 is located at the end of the upper support 4 and is used to support the inside of the heat pipe before it is fed into the rolling mechanism 5. The support input mechanism 6 also includes an inner support assembly 7 for supporting the inside of the heat pipe. Separation mechanism 8, which is located at the end of the upper support 4 away from the support input mechanism 6, is used to release the internal support of the heat pipe; The lowering mechanism 9 is located below the separating mechanism 8 and is used to transport the inner support assembly 7 into the circulation unit 3; The mounting mechanism 10 is located below the support input mechanism 6 and is used to transport the inner support component 7 into the support input mechanism 6.

[0023] In this embodiment, reference Figure 1 and Figure 2 The heat-conducting tube is placed in the support input mechanism 6 using a conveying mechanism (such as the conveyor belt 36 or hydraulic push rod in the prior art) or manually. The support input mechanism 6 inserts the inner support component 7 into the heat-conducting tube. Then, the rolling mechanism 5 performs the rolling operation. The rolling mechanism 5 is not modified and is the rectangular flat tube rolling mechanism 5 commonly used in the prior art, such as the GRM-180-3 precision rolling mill or the 1150 six-roll reversible cold rolling mill. After the heat-conducting tube is rolled, the separation mechanism 8 separates the inner support component 7 from the heat-conducting tube. The rolled heat-conducting tube is conveyed to the next processing line, and the inner support component 7 will be conveyed to the circulation unit 3 by the lower mechanism and then re-conveyed to the support input mechanism 6 with the installation mechanism 10 for recycling and continuous operation. This avoids the heat-conducting tube from developing inner wall bulges after rolling, which could lead to cracks and affect the service life of the heat-conducting tube.

[0024] In a further preferred embodiment of the invention, such as Figure 3 and Figure 4As shown, the support input mechanism 6 includes an input plate 11, which is connected to the end of the upper support 4. A wide groove 12 is provided on the top of the input plate 11, and a through groove 13 is provided on the bottom side wall of the wide groove 12. Input wheels 14 are rotatably connected to the two opposite side walls of the wide groove 12. A first motor 15 is fixedly connected to the bottom side of the input plate 11, and the output end of the first motor 15 is connected to the corresponding input wheel 14.

[0025] In this embodiment, reference Figure 3 and Figure 4 The heat pipe is conveyed from the conveying mechanism to the wide slot 12 on the input plate 11. The width of the slot 13 is smaller than the width of the heat pipe. When the end of the heat pipe moves into the wide slot 12, it will fit on the inner support assembly 7, and the outer wall will also fit against the input wheel 14. Then, driven by the first motor 15, the input wheel 14 is rotated, which in turn drives the heat pipe to move, so that the inner support assembly 7 is completely inside the heat pipe, thereby supporting the inner wall of the heat pipe.

[0026] In a further preferred embodiment of the invention, such as Figure 3 and Figure 4 As shown, the inner support assembly 7 includes an inner support column 16, which is disposed in the through groove 13. The end of the inner support column 16 away from the upper support 4 is tapered. The input plate 11 is provided with a blocking assembly 17 on the side near the upper support 4.

[0027] In this embodiment, reference Figure 3 and Figure 4 When the heat pipe moves into the wide groove 12, the end of the heat pipe will fit against the tapered end of the inner support column 16, and the edge of the pipe opening will fit against the tapered side of the inner support column 16, thereby lifting the inner support column 16 and inserting it into the heat pipe. The blocking component 17 blocks the inner support column 16 to prevent it from being pushed out by the heat pipe. When the inner support column 16 is fully inserted into the heat pipe, the heat pipe is driven by the rotation of the input wheel 14 to abut against the blocking component 17 and push the blocking component 17 away, so that the heat pipe can enter the rolling mechanism 5 for rolling.

[0028] In a further preferred embodiment of the invention, such as Figure 3 As shown, the blocking assembly 17 includes a notch 18, which is opened on the side of the wide slot 12 near the upper support 4. A torsion spring 19 is connected to the inner top sidewall of the notch 18, and a blocking shaft 20 is connected to the bottom end of the torsion spring 19. A blocking plate 21 for blocking the inner support column 16 is connected to the outer periphery of the blocking shaft 20.

[0029] In this embodiment, reference Figure 3The barrier plate 21 in the barrier assembly 17 will block the movement of the inner support column 16, so that the inner support column 16 can be fully inserted into the heat pipe. When the heat pipe moves to the barrier plate 21, the force of the heat pipe pushing the barrier plate 21 is greater than the force required to twist the torsion spring 19. Then the barrier plate 21 drives the rotation of the barrier shaft 20, which will also drive the torsion spring 19 to twist. After the barrier plate 21 is opened, the heat pipe can be separated from the wide groove 12 and then move into the rolling mechanism 5 for rolling. After the heat pipe is fully inserted into the rolling mechanism 5, the next heat pipe can enter the wide groove 12, and the next inner support column 16 will be conveyed into the through groove 13.

[0030] In a further preferred embodiment of the invention, such as Figure 5 and Figure 6 As shown, the separation mechanism 8 includes an output plate 22, which is connected to the end of the upper support 4 away from the input plate 11. An output groove 23 is provided on the top side of the output plate 22. Output wheels 24 are rotatably connected to the two inner sidewalls of the output groove 23. A second motor 25 is connected to the bottom side of the output plate 22. The output end of the second motor 25 is connected to the corresponding output wheel 24. Two slide grooves 26 are provided on the side of the output plate 22 near the upper support 4. Separation plates 27 are slidably connected in both slide grooves 26. Separation springs 28 are connected between the separation plates 27 and the inner sidewalls of the slide grooves 26. The sides of the two separation plates 27 that are close to each other are inclined.

[0031] In this embodiment, reference Figure 5 and Figure 6 After the heat pipe is rolled, it is moved by the rolling mechanism 5 to the output groove 23 on the output plate 22. During this process, the end of the heat pipe pushes the two separation plates 27. The inclined surfaces of the two separation plates 27 contact the end of the heat pipe and are pushed and squeezed. The separation plates 27 will slide in the slide groove 26. Then the heat pipe continues to move (it should be noted that the length of the inner support column 16 is greater than the length of the heat pipe, and the length of the inner support column 16 will be adjusted according to the length of the heat pipe). With the continuous movement of the heat pipe, the tapered end of the inner support column 16 will move to the separation plate 27. Then the separation plate 27 is subjected to the reaction force of the separation spring 28 and clamps the inner support column 16. At this time, the second motor 25 drives the output wheel 24 to move the heat pipe, which will gradually separate the heat pipe from the inner support column 16 so that the heat pipe can proceed to the next process and the inner support column 16 can be recycled.

[0032] In a further preferred embodiment of the invention, such as Figure 5 and Figure 6As shown, the lowering mechanism 9 includes a lowering groove 29, which is opened on the bottom side wall of the output groove 23. Two guide plates 30 are connected to the bottom of the output plate 22, and a lowering plate 31 is connected between the two guide plates 30. The end of the lowering plate 31 is inclined downward and extends into the conveying groove 2. A number of rotating rods 32 are rotatably connected to the top side wall of the lowering plate 31. A slot 33 for avoiding the inner support column 16 is opened on the bottom side wall of the upper support 4 at one end of the output plate 22.

[0033] In this embodiment, reference Figure 5 and Figure 6 After the heat pipe separates from the inner support column 16, the end of the inner support column 16 furthest from the upper support 4 will fall freely, causing it to fall from the lower groove to the lower plate. The end of the inner support column 16 vibrates upon hitting the lower plate 31, causing the other end to detach from the two separation plates 27 and fall completely onto the lower plate. The guide plate 30 is used to prevent the inner support column 16 from tilting or changing angle. Then, the rotating rod 32 reduces the friction between the inner support column 16 and the lower plate 31. (Refer to...) Figure 1 This allows the inner support column 16 to move into the conveying trough 2. A slot 33 is opened on one side wall of the upper support 4 to avoid the falling inner support column 16, so that the inner support column 16 can fall into the conveying trough 2 and then be conveyed by the circulation unit 3.

[0034] In a further preferred embodiment of the invention, such as Figure 7 , Figure 8 and Figure 9 As shown, the circulation unit 3 includes a bottom groove 34, which is opened on the bottom side wall of the conveying groove 2. The two ends of the inner side wall of the bottom groove 34 are rotatably connected to a rotating shaft 35. A conveyor belt 36 is sleeved on the two rotating shafts 35. A third motor 37 is connected to the side of the bottom support 1. The output end of the third motor 37 is connected to the corresponding rotating shaft 35.

[0035] In this embodiment, reference Figure 7 , Figure 8 and Figure 9 A bottom groove 34 is opened on the inner bottom side wall of the conveying trough 2. The third motor 37 drives the rotating shaft 35 to rotate, which in turn drives the conveyor belt 36 to rotate. When the inner support column 16 on the lower plate moves to the conveyor belt 36, the friction between the conveyor belt 36 and the inner support column 16 moves the entire inner support column 16 onto the conveyor belt 36. Then it is conveyed to the installation mechanism 10, so that the inner support column 16 can be moved back to the support input mechanism 6 for recycling.

[0036] In a further preferred embodiment of the invention, such as Figure 9As shown, the mounting mechanism 10 includes a hydraulic telescopic rod 38, which is fixedly installed at the bottom of the bottom support 1. The telescopic end of the hydraulic telescopic rod 38 extends to the bottom of the through groove 13 and is connected to a support plate 39, and is in contact with the inner support column 16. A clearance groove 40 for avoiding the support plate 39 is provided on the top side of the bottom support 1 at the position of the hydraulic telescopic rod 38. Two limiting plates 41 are fixedly connected to the bottom of the input plate 11.

[0037] In this embodiment, reference Figure 9 After the circulation unit 3 moves the inner support column 16 onto the support plate 39 on the hydraulic telescopic rod 38, the hydraulic telescopic rod 38 drives the support plate 39 to rise, causing the support plate 39 to move to the through groove 13, thereby driving the inner support column 16 to move into the through groove 13, so that the subsequent heat conduction pipe can be moved to the inner support column 16 to provide support.

[0038] In a further preferred embodiment of the invention, such as Figure 9 As shown, a support spring 42 is connected to the side of the bottom groove 34 near the mounting mechanism 10, and a blocking block 43 is connected to the top of the support spring 42. The blocking block 43 is located below the support plate 39.

[0039] In this embodiment, reference Figure 9 When the pallet 39 has not moved to the conveyor belt 36, it will be blocked by the blocking block 43 to prevent the inner support column 16 from moving to the position of the hydraulic telescopic rod 38 and affecting the subsequent conveying. After the inner support column 16 on the pallet 39 is carried away by the corresponding heat-conducting pipe sleeve, the hydraulic telescopic rod 38 retracts, causing the pallet 39 to descend. When the pallet 39 descends to the conveyor belt 36, it will press down on the blocking block 43 and squeeze the support spring 42. After the blocking block 43 descends, the inner support column 16 on the conveyor belt 36 will be conveyed to the pallet 39. After the inner support column 16 has completely fallen onto the pallet 39, the hydraulic telescopic rod 38 extends, and the blocking block 43 returns to its original position using the support spring 42 to block the next inner support column 16.

[0040] In a further preferred embodiment of the invention, such as Figure 3 and Figure 5 As shown, the inner support column 16 has a circular groove 44 on one end away from the upper support 4 and on two opposite sides, and a universal ball 45 is rotatably connected in the circular groove 44.

[0041] In this embodiment, reference Figure 3 A circular groove 44 is made at the tapered slope of the end of the inner support column 16, and a universal ball 45 is rotatably connected within the circular groove 44. (Refer to...) Figure 5To avoid insufficient friction when the separation plate 27 is clamping, the separation plate 27 clamps the universal ball 45 on the inclined surface of the tapered end of the inner support column 16. The universal ball 45 is used to limit the clamping force of the two separation plates 27, so as to prevent the inner support column 16 from being transported away with the heat pipe and affecting subsequent use. After the heat pipe separates from the inner support column 16, the inner support column 16 falls onto the lower plate 31. The universal ball 45 can reduce the friction between the separation plate 27 and the inner support column 16, so as to avoid affecting the descent of the inner support column 16.

[0042] Working principle: The heat pipe is conveyed from the conveying mechanism to the wide slot 12 on the input plate 11. Then, when the end of the heat pipe moves into the wide slot 12, it will be fitted onto the inner support assembly 7, and the outer wall will also be in contact with the input wheel 14. Then, driven by the first motor 15, the input wheel 14 is rotated, which in turn drives the heat pipe to move, so that the inner support assembly 7 is completely inside the heat pipe, thereby supporting the inner wall of the heat pipe. When the heat pipe moves into the wide groove 12, the end of the heat pipe will fit against the tapered end of the inner support column 16. The pipe end fits against the tapered side of the inner support column 16, thereby lifting the inner support column 16 and inserting it into the heat pipe. The blocking component 17 blocks the inner support column 16 to prevent it from being pushed out by the heat pipe. When the inner support column 16 is fully inserted into the heat pipe, the heat pipe is driven by the rotation of the input wheel 14 to abut against the blocking component 17 and push the blocking component 17 away, so that the heat pipe can enter the rolling mechanism 5. After the heat pipe is rolled, it is moved by the rolling mechanism 5 to the output groove 23 on the output plate 22. During this period, the end of the heat pipe will push the two separation plates 27. The inclined surfaces of the two separation plates 27 will contact the end of the heat pipe and be pushed and squeezed. The separation plates 27 will slide in the groove 26, and then the heat pipe will continue to move. As the heat pipe continues to move, one end of the tapered inner support column 16 will move to the separation plate 27. Then, the separation plate 27 is subjected to the reaction force of the separation spring 28, which causes the separation plate 27 to clamp the inner support column 16. At this time, the second motor 25 drives the output wheel 24 to move in contact with the heat pipe, which will cause the heat pipe to gradually separate from the inner support column 16, so that the heat pipe can proceed to the next process and the inner support column 16 can be recycled from below. This causes the conveyor belt 36 to rotate. When the inner support column 16 on the lower plate moves to the conveyor belt 36, the friction between the conveyor belt 36 and the inner support column 16 moves the entire inner support column 16 onto the conveyor belt 36. It is then transported to the mounting mechanism 10, so that the inner support column 16 can be moved back to the support input mechanism 6 for recycling.

[0043] It should be noted that the first motor 15, the second motor 25, and the third motor 37 in this application can be equipped with a controller at an appropriate location on the outside of the device, so as to control the first motor 15, the second motor 25, and the third motor 37.

[0044] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
