Description

Technical Field

[0001] The invention belongs to the technical field of heat exchanger component manufacturing, and specifically is an intelligent processing device for heat exchanger pipes. Background Art

[0002] A heat exchanger is a device used to transfer heat between different fluids. The basic working principle is to use a solid surface as a medium to allow two or more fluids to exchange heat without direct mixing. The fluid can be steam, hot water or hot oil on one side, and the other side is a liquid that needs to be heated or cooled. Among them, the fin heat exchanger is one of the more commonly used heat exchangers. It increases the heat exchange area by adding fins to the outside of the heat exchange tube, so that the fluid can contact more heat exchange area in the same time, thereby absorbing or releasing heat faster.

[0003] The fins in the fin heat exchanger are directly welded or mechanically fixed on the heat exchange tubes, but the head and tail of each heat exchange tube are welded together by a U-shaped tube, and the whole will be arranged in an S shape to improve the heat exchange efficiency. In the prior art, the U-shaped tube and the heat exchange tube are generally placed by special tooling. During the manual welding process, the U-shaped tube and the heat exchange tube will shake. This welding auxiliary means will make the gap between the welding surfaces larger, resulting in the U-shaped tube and the welded surface of the heat exchange tube not being able to fit well, thereby reducing the welding quality. For this reason, we provide a heat exchanger tube intelligent processing device. Summary of the invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention arranges the cooperation of structures such as the clamping assembly and the guiding assembly, so that the guiding plate moves and gradually pushes the guiding rod two and the guiding rod one, so that the guiding rod one moves to a horizontal state, and pushes the arc plate one to support the U-shaped tube through the parallel plate, and the arc plate one on the other side will also be in the same working state.

[0025] The present invention cooperates with structures such as a protective component and a heat exchange tube. When the clamping component clamps the heat exchange tube, the rubber pad on the protective plate will preferentially contact the outer periphery of the heat exchange tube. When the heat exchange tube moves, the rubber pad and the protective plate will slide on the second fixed plate, thereby preventing the outer periphery of the heat exchange tube from being damaged during the movement, and reducing the defective rate caused by welding.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 9 As shown, the present invention provides a heat exchanger tube intelligent processing device, comprising a workbench 1 and a hydraulic telescopic cylinder 10 located at the bottom of the workbench 1, a heat exchange tube 3 and a U-shaped tube 4 are placed on the workbench 1, a base 6 is fixed on the top of the hydraulic telescopic cylinder 10, and further comprising:

[0038] A movable plate 2 movably connected to the side of the workbench 1;

[0039] A guide assembly 5 fixedly mounted on a base 6;

[0040] The guide assembly 5 includes a support platform 51 fixedly mounted on the top of the base 6 and a threaded rod 52 threadedly penetrating the movable plate 2 and fixedly mounted on the support platform 51 on the top of the base 6, a guide plate 53 is movably connected to the support platform 51, and a guide rod 2 50 and a guide rod 1 54 are respectively hinged at both ends of both sides of the guide plate 53, and an end of the guide rod 1 54 away from the guide plate 53 is connected to an arc plate 1 56 through a parallel plate 55, and a spring telescopic rod 57 is respectively fixedly mounted on both sides of the support platform 51, and an arc plate 2 58 is respectively fixedly mounted on the movable end and the fixed end of the spring telescopic rod 57, and pressure sensors 59 are provided on both arc plates 2 58;

[0041] Two clamping assemblies 7 symmetrically arranged on the base 6;

[0042] The clamping assembly 7 includes a clamping plate 71 slidably mounted on the top of the base 6 and a fixed plate 72 fixed on the top of the base 6. The side of the clamping plate 71 is hinged with an extension plate 73. The middle part of the extension plate 73 is elastically hinged with the clamping plate 71 through a spring sheet 74. The extension plate 73 is elastically connected to the middle part of a bidirectional spring telescopic plate 75 through a tension spring 76. One side of the bidirectional spring telescopic plate 75 is hinged with the extension plate 73. The side of the fixed plate 72 is connected with a buckle plate 77 through two springs 78.

[0043] The thread penetrates through two displacement components 8 of the movable plate 2. The two displacement components 8 are symmetrically arranged on both sides of the threaded rod 52. The displacement components 8 are used to move the heat exchange tube 3.

[0044] A protection component 9 is arranged on the clamping component 7.

[0045] The push plate 53 is hinged to the clamping plate 71 through the guide rod 2 50 , the guide rod 2 50 and the guide rod 1 54 are both inclined, the threaded rod 52 is connected to the side of the push plate 53 through a bearing, and the parallel plate 55 is slidably installed on the top of the support platform 51 .

[0046] The hinge between the spring sheet 74 and the extension plate 73 slides on the side of the extension plate 73 through a slider, the elastic coefficient of the two-way spring telescopic plate 75 is greater than the elastic coefficient of the spring sheet 74, the elastic coefficient of the tension spring 76 is greater than the elastic coefficient of the spring 1 78, and the side of the two-way spring telescopic plate 75 is movably connected with the buckle plate 77.

[0047] A plurality of transverse grooves 11 are formed on the base 6 and the support platform 51 , and the parallel plate 55 and the clamping plate 71 move horizontally through the transverse grooves 11 .

[0048] Adopting the above solution: when the heat exchange tube 3 is located between the clamping plate 71 and the fixing plate 72, Figure 3 as well as Figure 4 The threaded rod 52 and the movable plate 2 shown in the figure are rotated, and the threaded rod 52 is moved to the right side in cooperation with the movable plate 2 through the thread thereon, and the guide plate 53 is moved synchronously and gradually pushes the guide rod 2 50 and the guide rod 1 54. Since the parallel plate 55 and the clamping plate 71 can only move horizontally through the transverse groove 11, first, the guide rod 1 54 will gradually move from an inclined state to a horizontal state, and will also push the arc plate 1 56 through the parallel plate 55, thereby forcing the side of the arc plate 1 56 to support the U-shaped tube 4, and the arc plate 1 56 on the other side will also be in the same working state. Even if the U-shaped tube 4 is placed on the top of the workbench 1, it is in an inclined state. When both ends of the U-shaped tube 4 are supported and corrected by the arc plate 1 56, the welded surface of the U-shaped tube 4 will remain in a fixed posture;

[0049] When the guide plate 53 pushes the second guide rod 50, its moving track is the same as that of the first guide rod 54, but the second guide rod 50 will push the two clamping plates 71 to move. Figure 6When the locking cam 75 is in the state of being lifted up, the locking cam 73 is in the state of being lifted up, and the locking cam 73 is in the state of being lifted up, so that the position of the locking cam 73 is obviously different from that of the locking cam 73.

[0050] like Figure 6 The two-way spring telescopic plate 75 shown in the figure moves up the buckle plate 77, which is no longer engaged with the two-way spring telescopic plate 75, and the spring 1 78 is compressed. Through the tension of the tension spring 76, the two-way spring telescopic plate 75 will be folded and no longer block the heat exchange tube 3, and the hydraulic telescopic cylinder 10 is controlled to descend, and the clamping assembly 7 is no longer in contact with the heat exchange tube 3. The heat exchange tube 3 and the U-shaped tube 4 after welding can be directly moved horizontally to start a new round of welding work, thereby improving the convenience of using the device. When the hydraulic telescopic cylinder 10 rises again and works, the pressure sensor 59 on the arc plate 2 58 will preferentially contact the outer periphery of the heat exchange tube 3 and the U-shaped tube 4. Due to the weight pressure of the heat exchange tube 3 and the U-shaped tube 4, the pressure value borne by the pressure sensor 59 is transmitted to the controller. When the pressure reaches the specified value, the controller will stop the lifting work of the hydraulic telescopic cylinder 10, thereby avoiding the heat exchange tube 3 from being tilted and affecting its work.

[0051] like Figures 1 to 4 , Figures 6 to 8 As shown, there are six protective components 9 and each group consists of three. One protective component 9 in each group is located at the bottom of the bidirectional spring telescopic plate 75, and the other two protective components 9 in each group are symmetrically arranged on the opposite surfaces of the clamping plate 71 and the fixing plate 72.

[0052] Each group of protective components 9 includes a fixed plate 91, a protective plate 92 and a spring 93, wherein two fixed plates 91 are respectively fixedly mounted on the opposite sides of the clamping plate 71 and the fixed plate 1 72, and another fixed plate 91 is fixedly mounted on the bottom of the bidirectional spring telescopic plate 75. The fixed plate 91 is elastically connected to the protective plate 92 through the spring 93. The fixed plate 91 is movably clamped with the protective plate 92, and a rubber pad is arranged at the bottom of the fixed plate 1 72.

[0053] Fins are welded on the outer circumference of the heat exchange tube 3 , and the fins are in a threaded shape. The workbench 1 is provided with slots that match the base 6 .

[0054] Using the above solution: Figure 6 As shown in the protective assembly 9, when the clamping assembly 7 clamps the heat exchange tube 3, the rubber pad on the protective plate 92 will preferentially contact the outer periphery of the heat exchange tube 3. When the heat exchange tube 3 moves, the rubber pad and the protective plate 92 will slide on the second fixing plate 91, so that the fins on the outer periphery of the heat exchange tube 3 will not be damaged during the movement. When the clamping assembly 7 no longer clamps the heat exchange tube 3, the second spring 93 will help the protective plate 92 to reset.

[0055] like Figure 6 and Fig. 9 As shown, the displacement assembly 8 includes an active rod 81 threadedly sleeved on the movable plate 2, a threaded bone 82 is arranged on the outer periphery of the active rod 81, a clamping plate 85 is movably mounted on the side of the active rod 81 through a gear 86, and an upper tooth plate 84 and a lower tooth plate 83 are meshed on the gear 86.

[0056] The lower tooth plate 83 is disposed on the side of the clamping plate 71 , and the upper tooth plate 84 is disposed on the side of the fixing plate 1 72 . Both the upper tooth plate 84 and the lower tooth plate 83 are horizontal.

[0057] The sides of the active rod 81 and the threaded rod 52 are both provided with a rotating handle, and the threaded bone 82 is engaged with the fin thread.

[0058] Using the above solution: Figure 6 As shown in the heat exchange tube 3, the clamping plate 71 and the fixing plate 72, when the clamping plate 71 and the fixing plate 72 clamp the heat exchange tube 3, the center point of the heat exchange tube 3 should be located on the longitudinal center line between the clamping plate 71 and the fixing plate 72, and in the process of the clamping plate 71 moving, it pushes the lower tooth plate 83, and the gear 86 will roll through the lower tooth plate 83 and the upper tooth plate 84, and the gear 86 will also always be located on the longitudinal center line, so that the threaded bone 82 can better mesh with the fin thread;

[0059] By rotating the threaded bone 82 through the active rod 81, the threaded bone 82 drives the heat exchange tube 3 to move through the fin and fit one side of the U-shaped tube 4. Since the active rod 81 is threadedly connected to the flap 2, the threaded bone 82 can move faster to avoid excessive rotation of the threaded bone 82, thereby damaging the surface of the fin.

[0060] The working principle and use process of the present invention:

[0061] When the heat exchange tube 3 is located between the clamping plate 71 and the fixing plate 1 72, the threaded rod 52 is rotated and moves to the right side in cooperation with the movable plate 2 through the threads thereon, and the guide plate 53 moves synchronously and gradually pushes the guide rod 2 50 and the guide rod 1 54, and the guide rod 1 54 will gradually move from an inclined state to a horizontal state, and will also push the arc plate 1 56 to support the U-shaped tube 4 from the side, and the arc plate 1 56 on the other side will also be in the same working state;

[0062] When the guide plate 53 pushes the guide rod 2 50, its moving trajectory is the same as that of the guide rod 1 54. The guide rod 2 50 will push the clamping plate 71 to move to one side, and the two-way spring expansion plate 75 will squeeze the extension plate 73. The extension plate 73 will gradually become vertical, and the lower end of the extension plate 73 will drive the two-way spring expansion plate 75 to descend, so that the protective component 9 at the bottom of the two-way spring expansion plate 75 gradually fits and clamps the outer periphery of the heat exchange tube 3. Finally, the protective component 9 on the side of the clamping plate 71 will cooperate with the protective component 9 on the side of the fixing plate 1 72 to clamp the heat exchange tube 3. At this time, the heat exchange tube 3 is fixed as a whole, and its welded surface will be opposite to the welded surface of the U-shaped tube 4.

[0063] The center point of the heat exchange tube 3 is located on the longitudinal center line between the clamp plate 71 and the fixed plate 72, and during the movement of the clamp plate 71, it pushes the lower tooth plate 83, and the gear 86 will roll through the lower tooth plate 83 and the upper tooth plate 84. The gear 86 will also always be located on the longitudinal center line, so that the threaded bone 82 can better engage with the fin thread. The threaded bone 82 is rotated by the active rod 81, and the threaded bone 82 drives the heat exchange tube 3 to move through the fin and fit one side of the U-shaped tube 4 and weld it.
