Description

Technical Field

[0001] The invention relates to the technical field of heat exchange tube processing, in particular to a support device and a movable adjustment component thereof, and applications in heat exchange tube production. Background Art

[0002] In the traditional heat exchange tube processing and manufacturing process, the displacement operation of the core head often relies on manual control by technicians with the help of auxiliary equipment. However, this manual adjustment method has limitations in the precise control of the core head positioning, and it is difficult to achieve a better level of accuracy.

[0003] A Chinese patent with announcement number CN221739155U discloses a tube stocking device and heat exchange tube production equipment, including a support body, an inclined support surface extending in a first direction and a second direction, the first direction is a horizontal direction consistent with the extension direction of the tube, and the second direction is perpendicular to the first direction and inclined relative to the horizontal plane.

[0004] A Chinese patent with announcement number CN221499658U discloses an automatic unloading assembly for processing heat exchange tubes, including an unloading rack, a first unloading trough and a second unloading trough are adjacently arranged at the front and rear of the front end of the unloading rack, and a portal frame is arranged between the first unloading trough and the second unloading trough, a second inclined surface inclined forward and downward is arranged on the top surface of the rear end of the unloading rack, a second support ejection assembly and a first support ejection assembly are adjacently arranged at the front and rear of the rear end of the unloading rack, a guide frame is arranged between the middle part of the rear end of the unloading rack and the portal frame, and the top surface of the guide frame is arranged as the first inclined surface inclined forward and downward.

[0005] Although the rapid unloading and conveying structure of the heat exchange tube can improve the processing efficiency of the rolling equipment for the heat exchange tube, due to the lack of flexible displacement and adjustment capability of the core head during the processing of the heat exchange tube, there is currently a method of fixing the core head position and cooperating with the rolling device to complete the processing by moving the heat exchange tube. However, this method will cause the rolling equipment to use one core head position for a long time to process the heat exchange tube, causing core head wear or even damage, affecting product production efficiency and prone to processing quality problems.

[0006] In addition, during the movement and adjustment of the core head in the heat exchange tube, the impurities in the heat exchange tube will be concentrated in the gap between the core head and the heat exchange tube. As the impurities accumulate more and more, the movement and adjustment of the core head in the heat exchange tube will be hindered, resulting in increased wear of the core head and the heat exchange tube, and even causing the core head to be stuck and unable to escape from the heat exchange tube.

[0021] Technical effects and advantages of the present invention:

[0022] 1. The present invention utilizes the first core head and the second core head to provide support for the heat exchange tube as a whole when the rolling turntable processes the heat exchange tube circumferentially. At the same time, after the rolling turntable can correspond to the second core head, the second core head replaces the first core head to correspond to the rolling turntable and continue to process the rear end of the heat exchange tube, thereby avoiding the problem of wear or damage of the first core head caused by the rolling turntable cooperating with the first core head to process the heat exchange tube for a long time.

[0024] 3. The present invention detects the degree of impurity accumulation between the first core head and the heat exchange tube through a pressure sensor. When the cleaning standard is reached, the rotating component is used to drive the first core head to rotate, and the stepper motor is used to drive the first core head to move toward the fixed component to remove the impurities between the first core head and the heat exchange tube, so as to avoid excessive accumulation of impurities, which may cause the first core head to be blocked in the heat exchange tube and increase wear.

However, the present invention may also be implemented in other ways different from the description. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below. Embodiment 1

[0037] See also Figure 1-9 This embodiment discloses a supporting device, including a supporting frame 1, a core head moving mechanism 2, a feeding assembly 3, a mounting frame 4, a fixing assembly 6 and a conveyor belt 7 are provided on the top of the supporting frame 1, and a rolling assembly 5 is provided on the front side of the mounting frame 4.

[0038] Among them, the feeding component 3 includes a feeding channel 301, and limit plates 302 are provided on both sides of the feeding channel 301. A material receiving cavity 303 is formed at the bottom of one end of the feeding channel 301. The material receiving cavity 303 is adapted to the heat exchange tube. A support component 304 is provided at one end of the material receiving cavity 303. The support component 304 corresponds to the fixing component 6. A propulsion mechanism is provided at the end of the feeding channel 301 away from the material receiving cavity 303. The propulsion mechanism transports the heat exchange tubes in the feeding channel 301 into the material receiving cavity 303 one by one, and the core head moving mechanism 2 is used to drive the heat exchange tube to move forward. The support component 304 and the fixing component 6 horizontally support both ends of the heat exchange tube. The rolling component 5 processes fins or threads on the surface of the heat exchange tube. The processed heat exchange tube is sent to the conveyor belt 7 under the cooperation and drive of the core head moving mechanism 2.

[0039] Specifically, the support assembly 304 includes an upper support plate 3041 and a lower support plate 3042, and a first electric telescopic rod 30411 and a second electric telescopic rod 30421 are respectively provided on both sides of the upper support plate 3041 and the lower support plate 3042, and the first electric telescopic rod 30411 and the second electric telescopic rod 30421 can respectively drive the upper support plate 3041 and the lower support plate 3042 to move horizontally, wherein the length of the upper support plate 3041 is smaller than the lower support plate 3042, and when the propulsion mechanism in the feed channel 301 transports the heat exchange tube into the material receiving chamber 303, the upper support plate 3041 does not interfere with the transportation of the heat exchange tube, and after the heat exchange tube enters the material receiving chamber 303, the upper support plate 3041 is driven to contract by the first electric telescopic rod 30411, so that the upper support plate 3041 and the lower support plate 3042 form a constraint support for the heat exchange tube.

[0040] Among them, the fixing component 6 includes a cylinder 601 and a claw plate component 602, the upper support plate 3041 and the lower support plate 3042 correspond to the claw plate component 602, the upper support plate 3041 and the lower support plate 3042 support the end of the heat exchange tube away from the claw plate component 602, and the claw plate component 602 supports the end of the heat exchange tube away from the upper support plate 3041 and the lower support plate 3042.

[0041] Specifically, the claw plate assembly 602 includes a support seat 6021, a movable groove 6022 is opened on one side of the support seat 6021, and a clamping block 6023 is movably connected inside the movable groove 6022. An electric control push rod is provided inside the support seat 6021, and the clamping block 6023 is driven to move by the electric control push rod. When the clamping block 6023 moves inward, it maintains a tight clamp on the heat exchange tube, and when the clamping block 6023 moves outward, the restriction on the heat exchange tube is released.

[0042] The core head moving mechanism 2 includes a stepper motor 201, which is fixedly mounted on the top of the support frame 1. A linear rail 207 is provided at a position corresponding to the top of the support frame 1 and the base 203. A lead screw 202 is provided at the output end of the stepper motor 201. The base 203 is threadedly connected to the lead screw 202. A slider is provided at a position corresponding to the base 203 and the linear rail 207. The slider and the linear rail 207 are limitedly slidably matched. A support rod 204 is provided on the top of the base 203. A rotating assembly 206 is provided at the end of the support rod 204 away from the base 203. The rotating assembly 206 includes a driving motor. A core head assembly 205 is provided at the output end of the rotating assembly 206. A heat exchange tube is sleeved on the outer side of the core head assembly 205. The heat exchange tube is supported by the core head assembly 205. By arranging multiple core heads in the core head assembly 205, the stability of the core head assembly 205 in supporting the heat exchange tube can be improved.

[0043] The stepper motor 201 drives the rotating assembly 206, the core head assembly 205 and the heat exchange tube to be transported forward horizontally through the threaded cooperation of the lead screw 202 and the base 203, and the limited sliding cooperation of the slider and the linear rail 207.

[0044] The core head assembly 205 includes a first extension section 2051, a second extension section 2052 and a fixed section 2053. The first extension section 2051 includes a connecting rod 20511, and a first core head 20512 is provided at one end of the connecting rod 20511. The second extension section 2052 includes a connecting tube 20521, and a second core head 20522 is provided at one end of the connecting tube 20521. The end of the connecting rod 20511 away from the first core head 20512 is limited and movably arranged inside the connecting tube 20521, and the end of the connecting tube 20521 away from the second core head 20522 is limited and movably arranged inside the fixed tube 20531.

[0045] The rolling assembly 5 includes a hydraulic lifter 501, a transmission motor 502 and a rolling turntable 503. The transmission motor 502 is arranged at the telescopic end of the hydraulic lifter 501, and the rolling turntable 503 is arranged at the driving end of the transmission motor 502. The horizontal heights of the transmission motor 502 and the rolling turntable 503 are adjusted by the hydraulic lifter 501. When the hydraulic lifter 501 moves upward, the rotating assembly 206 adjusts the angle of the heat exchange tube, or the stepping motor 201 drives the heat exchange tube to adjust its horizontal position through the threaded cooperation of the screw 202 and the base 203.

[0046] A locking mechanism 20532 is provided on the fixing cylinder 20531, and the locking mechanism 20532 is used to lock and fix the heat exchange tube so that the fixing cylinder 20531 and the heat exchange tube are fixed to each other.

[0047] A limiting groove 20523 is provided on the inner side of the connecting tube 20521 , and a limiting block 20513 is provided on the outer side of the connecting rod 20511 . The limiting block 20513 is slidably disposed inside the limiting groove 20523 .

[0048] When in use, the heat exchange tubes to be processed are pre-stored inside the feed channel 301, and the propulsion mechanism inside the feed channel 301 transports the heat exchange tubes into the receiving chamber 303 one by one. When each heat exchange tube is transported to the bottom of the receiving chamber 303, the lower support plate 3042 corresponds to one end of the heat exchange tube, and the first electric telescopic rod 30411 drives the upper support plate 3041 to retract through the contraction of the telescopic end. At this time, the outer side of the heat exchange tube is tightly fitted with the inner wall of the upper support plate 3041 and the inner wall of the lower support plate 3042. Then the stepper motor 201 is started, and the base 203 is driven to move horizontally through the threaded cooperation of the lead screw 202 and the base 203, so that the fixed cylinder 20531 enters the interior of the heat exchange tube, and the fixed cylinder 20531 is locked and fixed to the heat exchange tube through the locking mechanism 20532. When the stepper motor 201 drives the base 203 to move, the heat exchange tube moves synchronously with the base 203 to adjust the horizontal position of the heat exchange tube and make the end of the heat exchange tube away from the support assembly 304 correspond to the middle of the support seat 6021. Driven by the electric control push rod in the support seat 6021, the clamp 6023 is driven by the electric control push rod to move and position and clamp the end of the heat exchange tube away from the support assembly 304. When the stepper motor 201 drives the heat exchange tube to be transported forward, the electric control push rod contracts to release the clamp 6023 from the tight restriction on the heat exchange tube. When the heat exchange tube stops moving, the electric control push rod keeps the tightness on the heat exchange tube, and cooperates with the upper support plate 3041 and the lower support plate 3042 to limit the two ends of the heat exchange tube, thereby improving the stability of the rolling turntable 503 in processing the heat exchange tube.

[0049] Next, driven by the stepper motor 201, each position of the heat exchange tube corresponds to the rolling turntable 503 in turn, and under the control of the hydraulic lifter 501 on the horizontal height of the transmission motor 502 and the rolling turntable 503, each position of the heat exchange tube is rolled. In this process, the first core head 20512 is driven to rotate by the rotating component 206, and an electromagnetic lock is provided on the inner side of the limit groove 20523. The electromagnetic lock is used to lock and fix the connecting rod 20511 inside the limit groove 20523. An electromagnetic latch is provided on the inner side of the fixed cylinder 20531. The electromagnetic latch is used to lock and fix the connecting cylinder 20521 inside the fixed cylinder 20531, so that the fixed cylinder 20531 and the connecting cylinder 20521 can rotate synchronously with the connecting rod 20511.

[0050] At this time, the stepper motor 201 will drive the heat exchange tube forward, so that each position at the rear end of the heat exchange tube moves forward in sequence and corresponds to the rolling turntable 503. Correspondingly, when the stepper motor 201 drives the heat exchange tube forward, the clamping block 6023 is driven by the electric control push rod to expand outward synchronously. When the stepper motor 201 stops driving the heat exchange tube to move, the clamping block 6023 is driven by the electric control push rod to move inward synchronously to keep the heat exchange tube tight again.

[0051] When the clamp 6023 positions and clamps the heat exchange tube, and the locking mechanism 20532 locks and fixes the fixed cylinder 20531 and the heat exchange tube, the electromagnetic lock in the limit groove 20523 releases the lock on the connecting rod 20511. At this time, driven by the stepper motor 201, the base 203 moves toward the direction of the stepper motor 201. At the same time, driven by the connecting rod 20511, the first core head 20512 moves toward the rear end of the heat exchange tube, so that the first core head 20512 moves backward and corresponds to the rolling turntable 503 again, thereby ensuring the processing of each position of the heat exchange tube by the rolling turntable 503, and maintaining the corresponding support of the first core head 20512 to the heat exchange tube during processing.

[0052] The first core head 20512 and the second core head 20522 can support the heat exchange tube as a whole when the rolling turntable 503 processes the heat exchange tube in the circumferential direction, thereby maintaining the stability of the heat exchange tube during processing.

[0053] In order to prevent the first core head 20512 from being worn or damaged due to the long-term cooperation between the rolling turntable 503 and the first core head 20512 for processing the heat exchange tube, after the rolling turntable 503 can correspond to the second core head 20522, the second core head 20522 replaces the first core head 20512 to correspond to the rolling turntable 503 and continue to process the rear end of the heat exchange tube. When the clamping block 6023 positions and clamps the heat exchange tube, and the locking mechanism 20532 locks and fixes the fixing cylinder 20531 and the heat exchange tube, the fixing cylinder 20531 is locked. 1 releases the lock on the connecting tube 20521, and the electromagnetic lock in the limiting groove 20523 keeps the connecting rod 20511 locked and fixed. When the stepping motor 201 drives the base 203 to move in the direction of the stepping motor 201, the second core head 20522 will move toward the rear end of the heat exchange tube, so that the second core head 20522 keeps corresponding to the position of the rolling turntable 503. The second core head 20522 cooperates with the stepping motor 201 and the rolling turntable 503 to complete the processing of the heat exchange tube behind the second core head 20522.

[0054] When the rolling turntable 503 completes the local processing of the heat exchange tube and the heat exchange tube needs to be transported forward, the electromagnetic pin in the fixed cylinder 20531 keeps the connecting cylinder 20521 locked, the locking mechanism 20532 keeps the fixed cylinder 20531 and the heat exchange tube locked, and the electromagnetic lock in the limit groove 20523 keeps the connecting rod 20511 locked. Then, driven by the stepper motor 201, the heat exchange tube moves forward synchronously with the base 203. Driven by the electric control push rod, the clamping block 6023 expands outward when the heat exchange tube is transported forward. When the stepping motor 201 stops driving the heat exchange tube to move, the clamping block 6023 keeps tight against the heat exchange tube driven by the electric control push rod.

[0055] And while the first core head 20512 rotates, the connecting cylinder 20521 and the fixed cylinder 20531 rotate synchronously, and cooperate with the hydraulic lifter 501 to drive the transmission motor 502 and the rolling turntable 503 to move up and down, and the circumference of the heat exchange tube is processed. During this process, the first core head 20512 and the second core head 20522 rotate synchronously with the heat exchange tube to avoid the first core head 20512 and the second core head 20522 stopping when the heat exchange tube rotates, thereby increasing the wear on the inner wall of the heat exchange tube.

[0056] After the circumferential processing of the heat exchange tube is completed, the fixing cylinder 20531 and the heat exchange tube are locked by the locking mechanism 20532, and the upper clamp 6023 releases the tightness of the heat exchange tube. Driven by the stepper motor 201, the heat exchange tube is transported to the conveyor belt 7 through the threaded cooperation of the lead screw 202 and the base 203. Then, driven by the stepper motor 201, the base 203, the first core head 20512 and the second core head 20522 are moved to the side of the feed channel 301 close to the stepper motor 201, so that the subsequent heat exchange tube to be processed is transported to the material receiving chamber 303 driven by the propulsion mechanism, and then driven by the stepper motor 201, the first core head 20512 and the second core head 20522 are inserted into the interior of the heat exchange tube again, so as to continue to process the subsequent heat exchange tube. Embodiment 2

[0057] See also Figure 1-9 As shown, in the process of processing the heat exchange tube using the rolling turntable 503 and the first core head 20512, as the stepping motor 201 drives the first core head 20512 to move horizontally in the heat exchange tube through the base 203, more and more impurities will accumulate in the gap between the first core head 20512 and the heat exchange tube. When the heat exchange tube is processed, the friction between the first core head 20512 and the heat exchange tube will be increased, and the wear degree of the first core head 20512 will be increased. At the same time, the processing accuracy of the heat exchange tube will be affected by the influence of impurities. In this regard, the following embodiments are provided to solve the above problems:

[0058] A lifting groove 20514 is provided on the outer side of the first core head 20512, a spring 20515 is provided on the inner side of the lifting groove 20514, a lifting block 20516 is provided on the top of the spring 20515, a bottom slope 20517 is provided on the bottom side of the lifting block 20516 close to the second core head 20522, and a pressure sensor 20518 is provided inside the lifting block 20516.

[0059] An extension plate 20525 is provided on one side of the second core head 20522 close to the first core head 20512 . The extension plate 20525 corresponds to the lifting slot 20514 . A top of one end of the extension plate 20525 close to the first core head 20512 is provided as a top slope 20526 .

[0060] In use, since the first core head 20512 enters from the rear end of the heat exchange tube and moves horizontally in the heat exchange tube, impurities are concentrated on the side of the first core head 20512 close to the fixing assembly 6. The pressure sensor 20518 has a preset pressure threshold value P1. When the pressure sensor 20518 detects that the pressure threshold value reaches P1, it actively determines that the accumulation of impurities between the first core head 20512 and the heat exchange tube has reached a level that aggravates the wear of the first core head 20512. At this time, The electromagnetic lock in the limit groove 20523 releases the lock on the connecting rod 20511, the fixed cylinder 20531 keeps the lock on the connecting cylinder 20521, and the locking mechanism 20532 keeps the fixed cylinder 20531 and the heat exchange tube locked. Driven by the stepper motor 201, the base 203 moves in the direction of the stepper motor 201, and then the first core head 20512 moves in the direction of the second core head 20522. When the first core head 20512 and the second core head 20522 are docked, the extension plug plate 20525 is inserted into the lifting groove 20514. Under the support of the extension plug plate 20525, the spring 20515 is expanded. At the same time, the outer side of the lifting block 20516 is pressed against the inner wall of the heat exchange tube. Then the locking mechanism 20532 releases the locking of the fixed cylinder 20531 and the heat exchange tube. At this time, the clamping block 6023 on the support seat 6021 keeps the heat exchange tube locked under the drive of the electric control push rod. By pressing tightly against the rotating component 206 and the starting of the stepper motor 201, the first core head 20512 slowly pushes the impurities on its front side toward the fixed component 6 during the rotation process, so as to remove the impurities in the heat exchange tube, and the impurities are pushed out of the heat exchange tube by the first core head 20512. Before the impurities are moved out of the heat exchange tube, the cylinder 601 can drive the claw plate component 602 to move away from the conveyor belt 7 to prevent the impurities removed from the heat exchange tube from falling directly onto the conveyor belt 7.

[0061] In addition, during the processing of the heat exchange tube by the rolling turntable 503, the heat exchange tube is subjected to uneven force as a whole, and the heat exchange tube is partially deformed, resulting in an inward bulge in the heat exchange tube. The bulge in the heat exchange tube will block the first core head 20512, resulting in the first core head 20512 being unable to flexibly move and adjust its position in the heat exchange tube, and at the same time hindering the first core head 20512 from coming out of the heat exchange tube. In this regard, the following embodiments are provided to solve the above problems:

[0062] The edges of both sides of the first core head 20512 and the second core head 20522 are set to be smooth curved surfaces so that the protrusions in the heat exchange tube correspond to the gap between the first core head 20512 and the heat exchange tube.

[0063] During use, a pressure threshold value P2 is preset in the pressure sensor 20518, and the pressure threshold value P2>the pressure threshold value P1. The first core head 20512 is located in the heat exchange tube near the fixed component 6. When the protruding part in the heat exchange tube contacts the first core head 20512, the pressure threshold value in the pressure sensor 20518 will reach P2. At this time, the first core head 20512 is limited by the protruding part and cannot move toward the second core head 20522. At this time, the fixed cylinder 20531 keeps the fixed cylinder 20531 and the heat exchange tube locked and fixed through the locking mechanism 20532. The electromagnetic pin in the fixed cylinder 20531 releases the lock on the connecting cylinder 20521, so that the anti-slip ring 20524 can rotate and move horizontally inside the fixed cylinder 20531, and the limit The electromagnetic lock in the groove 20523 keeps the connection rod 20511 locked, and then, driven by the stepper motor 201, the first core head 20512 and the second core head 20522 are synchronously moved toward the fixed component 6 in cooperation with the base 203, so that the second core head 20522 moves to a position close to the raised portion, and then the electromagnetic lock in the limit groove 20523 releases the lock on the connection rod 20511, and then driven by the stepper motor 201, the first core head 20512 moves toward the second core head 20522. When the pressure sensor 20518 detects that the pressure threshold reaches P2, the raised portion inside the heat exchange tube is located in the gap between the first core head 20512 and the heat exchange tube, but the extension plug plate 20525 is not inserted into the lifting groove 20514. , under the limiting effect of the limiting groove 20523 on the limiting block 20513, the second core head 20522 rotates synchronously when the rotating component 206 drives the first core head 20512 to rotate. At this time, the first core head 20512 first eliminates the protrusion on the inner wall of the heat exchange tube to release the limiting effect of the protrusion on the first core head 20512. At this time, the pressure threshold detected by the pressure sensor 20518 is lower than P2. At this time, the rotating component 206 is closed, and the fixed cylinder 20531 keeps the connection cylinder 20521 locked through the electromagnetic latch. The position of the connection cylinder 20521 remains unchanged. Driven by the stepping motor 201, the first core head 20512 slowly moves toward the second core head 20522. As the first core head 2051 2 moves toward the second core head 20522, and the top inclined surface 20526 on the extension plug plate 20525 cooperates with the bottom inclined surface 20517 on the lifting block 20516, so that the lifting block 20516 moves outwards linearly. During this process, the pressure threshold detected by the pressure sensor 20518 will reach P2 again. At this time, the electromagnetic latch in the fixed cylinder 20531 releases the lock on the connecting cylinder 20521, and the rotating component 206 is started to continue to rotate and drive the first core head 20512 and the second core head 20522, so that the protrusion in the gap between the heat exchange tube and the first core head 20512 is gradually eliminated. When the top inclined surface 20526 on the extension plug plate 20525 is completely inserted into the interior of the lifting slot 20514,The outer side of the lifting block 20516 is in contact with the inner wall of the heat exchange tube under the standard state. At this time, the raised area in the gap between the heat exchange tube and the first core head 20512 is completely smoothed during the rotation of the first core head 20512, thereby ensuring the smoothness of the curved surface inside the heat exchange tube and avoiding the problem of impurities accumulating due to the raised area in the gap between the heat exchange tube and the first core head 20512 not being completely smoothed.
