Description

Technical Field

[0001] The present invention relates to the technical field related to heat exchanger bending devices, and in particular to a heat exchanger bending device with uniform force. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a cold fluid. They play a vital role in chemical, petroleum, power, food, and many other industrial processes. In chemical production, heat exchangers can serve as heaters, coolers, condensers, evaporators, and reboilers, among other applications. The core function of a heat exchanger is to achieve efficient energy utilization through heat transfer, and its specific functions span multiple areas of industrial production and daily life. U-tube heat exchangers bend each tube into a U-shape and secure it to a single tubesheet, allowing the tube bundle to expand and contract freely, eliminating thermal stress and improving the stability and service life of the heat exchanger. However, bending a heat exchanger can cause deformation due to various reasons, significantly affecting alignment. This deformation can alter the flow path of the fluid within the heat exchanger, affecting its heat transfer efficiency and overall performance. Existing support technologies for the interior of tubes are poor and cannot support the interior of long tubes, leaving a certain risk of deformation during bending. Summary of the Invention

[0028] Method of use of the present invention:

[0029] In the initial state:

[0030] The rack 23 does not exceed the range of the bending table 11, the rotating plate 24 is parallel and aligned with the fixed plate 28, the lifting plate 39 is at the top end of the No. 1 limit rod 38, the oil cylinder 40 is full of oil, the No. 2 hydraulic rod 32 is in a fully retracted state, the No. 2 electric push rod 53 is in a fully retracted state, the torsion spring between the blocking plate 69 and the No. 2 inner wall plate 68 is in a normal state, the attraction block 65 is completely absorbed by the electromagnet 63, the spring 67 is in a compressed state, the telescopic rod 66 is in a retracted state, the No. 1 hydraulic rod 71 is in a retracted state, the oil pipe 16 is full of oil, the sliding plate 60 is at the two ends of the No. 2 limit rod 59, and the No. 1 electric push rod 73 is partially extended.

[0031] When the user needs to use this device, the user needs to manually insert the oil pipe 16 into the tube 42 that needs to be deformed, and ensure that the oil pipe 16 passes through the tube 42, and then the user places the tube 42 on all the guide rollers 75 through external equipment or manpower, so that the tube 42 is stably supported by the guide rollers 75, and then the user aligns the end of the tube 42 close to the rotating plate 24 with the No. 2 fixed block 74 closest to the rotating plate 24, and then the user adjusts the size of the tube 42 to the parameters that need to be bent, and then the user needs to hold the oil pipe 16 with one end of the No. 1 fixed block 62, so that the No. 2 inner wall support plate 68 is roughly aligned with the end of the tube 42 close to the rotating plate 24, and then the user controls the electromagnet 63 to cut off the power through the console 12. After the electromagnet 63 is powered off, the The spring 67 is no longer restricted and will begin to reset. The telescopic rod 66 begins to extend under the action of the spring 67, so that the No. 2 inner wall support plate 68 is against the inner wall of the opening at one end of the tube 42, and the blocking plate 69 is placed outside the tube 42. Then, the No. 5 motor 14 is driven to start through the console 12. After the No. 5 motor 14 is started, its motor shaft will drive the reel 15 to rotate, thereby reeling in the oil pipe 16. As the oil pipe 16 is reeled in, the excess part of the oil pipe 16 will be reeled in, and the No. 1 fixed block 62 will be pulled, and the blocking plate 69 will be against one end of the tube 42 until the oil pipe 16 is in a straightened state. At this time, the torsion spring between the blocking plate 69 and the No. 2 inner wall support plate 68 has not been deformed. At this time, the user can stop the drive of the No. 5 motor 14 through the console 12.

[0032] Then the user can start the device through the console 12. After the device is started, the console 12 will drive the No. 2 electric slider 51 to start. After the No. 2 electric slider 51 is started, it will start to slide, so that the No. 2 electric slider 51 is aligned with the center line of the No. 1 electric push rod 73, so that the No. 2 electric slider 51 is aligned with the center line of the tube 42. Then the console 12 will drive the No. 2 electric push rod 53 to start, so that the No. 2 electric push rod 53 starts to extend. Due to the parameters of the tube 42 entered in advance, the No. 2 electric push rod 53 will extend to a certain length and stop automatically, so that the moving roller 55 is in contact with the surface of the tube 42. Then the No. 2 motor 54 and the No. 5 motor 14 will be started under the action of the console 12. After the No. 2 electric push rod 53 is started, it will drive the moving roller 55 to rotate. As the moving roller 55 rotates, the tube 42 is driven by friction to move toward the rotating plate 24. The guide roller 75 rotates, and the No. 5 motor 14 will also drive the reel 15 to move to pay out the oil pipe 16 so that the oil pipe 16 moves together with the tube 42 and always keeps it taut until the tube 42 moves the parameter distance entered in advance by the console 12. The No. 2 motor 54 and the No. 5 motor 14 will stop by themselves, and then the No. 4 electric slider 26 and the No. 3 electric slider 30 will be in the The control console 12 is activated, and the No. 4 electric slider 26 and the No. 3 electric slider 30 are activated, which will drive the limit block 35 and the bending block 27 to move, so that the bending block 27 and the limit block 35 are pressed against the tube 42, and the tube 42 is also in contact with the bending roller 20. Then the control console 12 will activate the oil pump 41, and after the oil pump 41 is activated, the oil in the oil cylinder 40 will be driven to be poured into the reel 15, and then poured into the oil pipe 16, so that the No. 1 hydraulic rod 71 begins to extend under the action of the oil, and as the No. 1 hydraulic rod 71 extends, the No. 1 inner wall support plate 72 will press against the tube 42, and the oil pump 41 will pour the oil into the reel 15. The amount is also determined by the size parameters entered in advance in the console 12, and the inner wall of the tube 42 is pressed against the inner wall of the tube 42 by the No. 1 inner wall support plate 72, so that the tube 42 needs to maintain a certain supporting force at the bending point to prevent the tube 42 from deforming when bending, and then the console 12 will start the No. 6 motor 21. After the No. 6 motor 21 is started, its motor shaft will drive the gear 22 to rotate, and the rotation of the gear 22 will drive the rack 23 to translate, and as the gear 22 rotates, it will drive the rotating block 19 and the bending roller 20 to rotate, thereby driving the rotating plate 24 to rotate, so that under the action of the rotation of the bending block 27 and the rotating plate 24, the tube 42 is bent, and as the rack 23 moves,The oil in the activity space 47 will enter the No. 2 hydraulic rod 32 through the connecting pipe 48, thereby starting to extend the No. 2 hydraulic rod 32. As the No. 2 hydraulic rod 32 extends, the limit block 35 drives the tube 42 to move synchronously, thereby assisting in bending. When the tube 42 completes a single bending, the No. 3 electric slider 30 and the No. 4 electric slider 26 start to reset under the action of the console 12, so that the bending block 27 and the limit block 35 no longer press against the tube 42, and then the No. 6 motor 21 will start again to reverse, thereby resetting the rotating plate 24 and the rack 23, and the console 12 starts the No. 2 electric push rod 53 again to make the moving roller 55 press against The tube 42 is held in place to prevent the tube 42 from rotating subsequently. Then, the No. 1 electric slider 18 is started under the action of the console 12 and moves out of the range limited by the bending roller 20. Then, the No. 1 electric push rod 73 is fully extended under the action of the console 12 to lift the tube 42. The No. 2 electric push rod 53 is also contracted synchronously to keep the tube 42 stable. The No. 2 motor 54 will be started under the action of the console 12, thereby driving the moving roller 55 to rotate, so that the tube 42 moves on the guide roller 75 toward the rotating plate 24 until it moves to the next bending position. Then, the No. 1 motor 36 will be started under the action of the console 12. After the No. 1 motor 36 is started, its motor shaft will The first screw 37 will be driven to rotate, thereby driving the lifting plate 39 to rise and fall on the first limit rod 38 through the rotation of the first screw 37. The lifting plate 39 will make the center lines of the steering roller 44 and the tube 42 in the same horizontal plane according to the parameters entered in advance, and then the third motor 57 will be started under the action of the console 12. After the third motor 57 is started, its motor shaft will drive the second screw 58 to rotate, thereby driving the sliding plate 60 to move until the steering roller 44 contacts the surface of the tube 42. Due to the parameters entered in advance, the third motor 57 will be started until the steering roller 44 stops when it is in contact with the tube 42, and then the console 12 will drive the second motor The push rod 53 and the No. 4 motor 45 are started, and the No. 2 electric push rod 53 will start to drive the moving roller 55 to reset. After the No. 4 motor 45 is started, its motor shaft will drive the steering roller 44 to rotate, thereby driving the tube 42 to rotate a certain angle to facilitate the next bending through the friction between the steering roller 44 and the tube 42. Then, the No. 2 electric push rod 53 and the No. 3 motor 57 are started, and the No. 2 electric push rod 53 starts to rise and fall until the moving roller 55 is against the tube 42. The No. 3 motor 57 drives the sliding plate 60 to reset, so that the steering roller 44 is no longer in contact with the tube 42. Then, the No. 1 motor 36 will drive the lifting plate 39 to reset, and then under the action of the console 12,The No. 1 electric push rod 73 and the No. 1 electric slider 18 will start to reset, thereby driving the tube 42 to reset, and the moving roller 55 will always keep the tube 42 stable under the action of the No. 2 electric push rod 53. The No. 4 electric slider 26 and the No. 3 electric slider 30 will start again under the action of the console 12. The bending block 27 and the limit block 35 will contact with the tube 42, thereby keeping the tube 42 stable. The No. 2 electric push rod 53 starts to reset under the action of the console 12, and the moving roller 55 no longer contacts with the tube 42. The console 12 will drive the oil pump 41 to start, thereby pumping out the oil in the No. 1 hydraulic rod 71, so that the No. 1 hydraulic rod 71 and the No. 1 inner wall plate 72 are reset. The console 12 will drive the No. 5 motor 14 to start. Then the oil pipe 16 begins to be reeled in, and the No. 2 inner wall support plate 68 always sticks to the inner wall of the pipe 42. As the oil pipe 16 is reeled in, the torsion spring between the blocking plate 69 and the No. 2 inner wall support plate 68 will be compressed and deformed, and the blocking plate 69 will flip over. The No. 2 inner wall support plate 68 moves in the pipe 42 under the drag of the oil pipe 16 until the oil pipe 16 is reeled in a certain length. At this time, the No. 1 fixed block 62 and the No. 1 inner wall support plate 72 arrive at the next bend. Then the oil pump 41 will be started under the action of the console 12, and the No. 1 hydraulic rod 71 will start to extend again. The No. 1 inner wall support plate 72 will be in contact with the inner wall of the pipe 42, and then the above steps will be repeated to start the next bend. This reciprocating process will continue until the pipe 42 is bent. The No. 5 motor 14 will be started to completely separate the oil pipe 16 from the pipe 42.
