[0001] The invention relates to the technical field of fin tube threading, and in particular to a fin tube threading device and method. Background Art

[0002] Refers to the process of installing fins on the tubes. By increasing the surface area of ​​the tubes, the heat exchange efficiency is improved. Therefore, the corresponding fins need to be installed on the outer wall of the heat exchange tubes. However, the following problems usually occur during the installation process:

[0003] First, the fin is usually a complete metal sheet with a through hole, so that the complete metal sheet is sleeved on the outer wall of the corresponding heat exchange tube, but such a setting usually requires the fin to pass through the heat exchange tube first, and then these multiple fins are fixed to the outer wall of the heat exchange tube, but this usually requires first sleeve, and then fixation, but these fins can only pass through the end of the heat exchange tube, which will lead to the problem of reduced installation efficiency;

[0004] Secondly, during the fixing process, since the fin is a complete metal sheet, it will be more difficult to fix it on the heat exchange tube.

[0022] Preferably, both the storage fins and the mounting fins are provided with slots adapted to the heat exchange metal tube buckles.

[0023] A method for processing fins through tubes, the specific operation steps are as follows:

[0024] S1: First, a plurality of storage fins are placed in a storage box, and then a driving device is turned on to drive the storage box to slide horizontally on the heat exchange metal tube, wherein the push plate pushes the storage fins toward the bottom hole under the action of the first return spring;

[0025] S2: Then turn on the driving motor, so that the driving motor drives the driving gear to rotate, and the meshing rotating gear rotates on the fixed frame. At the same time, the mounting ring is coaxially mounted on one end of the rotating gear through the mounting bolts, so that the mounting ring can also be driven to rotate coaxially;

At the same time, the installation fins will also fall on the curved plate and squeeze the trigger button, and disconnect the electromagnetic generator;

[0029] S6: When the electromagnetic generator is not disconnected, the magnetic field generated by the electromagnetic generator continues to attract the metal iron block in the heat exchange metal tube and moves with the tube support part. When the electromagnetic generator is disconnected, the lifting rod that originally attracted the iron loses its suction force and falls down. At the same time, the circuit system is connected and the electric push rod is turned on. The electric push rod drives the push rod to retract.

[0030] S7: Push the extrusion plate to extrude the expanded heat exchange metal tube and squeeze the slot of the metal fin to complete the fixation of the fin installed on the heat exchange metal tube. At the same time, the fin needs to be fixed by shrinking the slot to allow the fin to be stuck on the heat exchange metal tube to complete the secondary fixation of the fin.

[0031] The beneficial effects of the present invention are:

[0032] 1. In the present invention, since the mounting ring is detachable, the mounting ring with different numbers of side grooves can be replaced. The symmetrically opened side grooves form a group. Therefore, when the mounting ring rotates one circle, the more groups there are, the more times the intercepting plate can be extended and retracted in the side hole, thereby controlling the distance between two adjacent mounting fins.

[0033] 2. In the present invention, when the extrusion plate is pushed to extrude the area where the heat exchange metal tube is located, and the slots of the metal fins are squeezed, the fins installed on the heat exchange metal tubes are fixed. At the same time, the fins need to be fixed by shrinking the slots so that the fins are stuck on the heat exchange metal tubes to complete the secondary fixation of the fins.

[0044] Reference Figure 1-Figure 7 A fin processing and tube-threading device comprises a heat exchange metal tube 1, a plurality of metal fins 3 and a driving device. A storage box 2 is provided on the heat exchange metal tube 1, and the driving device drives the storage box to move on the heat exchange metal tube 1. The metal fins 3 comprise storage fins 301 and mounting fins 302. The storage fins 301 are multiple and linearly placed in the storage box 2. The storage fins 301 and the mounting fins 302 are both provided with slots that are snap-fitted with the heat exchange metal tube 1.

[0045] Multiple interception plates 20 are symmetrically arranged in two, and the interception plates 20 slide through the side holes 19. The interception plates 20 are chamfered on the side facing the storage fins 301. The interception plates 20 are located on the side of the bottom hole and are used to intercept the storage fins 301. The push plate 4 and the interception plates 20 are located at both ends of the multiple groups of storage fins 301. A push plate 4 is also provided in the storage box 2, and a first return spring 5 for pushing the push plate 4 to move toward the bottom hole is also provided in the storage box 2. The symmetrical side walls of the storage box 2 are all provided with side holes 19.

[0046] The storage fin 301 is arranged in the storage box 2, the mounting fin 302 is mounted on the heat exchange metal tube 1, the storage box 2 slides on the heat exchange metal tube 1 through the bottom sliding frame 6, the storage box 2 is provided with a bottom hole, and the storage fin 301 slides out of the storage box 2 through the bottom hole.

[0047] First, place multiple storage fins 301 in the storage box 2, and then turn on the driving device to drive the storage box 2 to slide horizontally on the heat exchange metal tube 1, wherein the push plate 4 pushes the storage fins 301 toward the bottom hole under the action of the first return spring 5. Since the other ends of the multiple storage fins 301 are blocked by the interception plate 20 at this time, the storage fins 301 cannot reach above the bottom hole at this time.

[0048] The bottom of the storage box 2 is fixed with limiting plates 14 symmetrically arranged on both sides of the bottom hole, and the bottom of the limiting plates 14 is fixed with curved panels 15 adapted to the metal fins 3, so that the fins 302 can be supported and installed.

[0049] A trigger button 17 is provided on the curved plate 15 , and a plurality of side baffles 16 for limiting the position of the metal fins 3 are fixed on the limiting plate 14 and the curved plate 15 on the side facing the mounting ring 9 .

[0050] The storage box 2 is provided with a plurality of intercepting plates 20 to prevent the storage fins 301 from sliding out. The storage box 2 is provided with an intermittent feeding part for driving the intercepting plates 20 to extend and retract. The intermittent feeding part includes a rotating gear 8. A fixing frame 7 is fixed to the outer wall of the storage box 2, and the rotating gear 8 rotates on the fixing frame 7 through a limit rod 11 and an annular groove 12. The mounting ring 9 is coaxially mounted on one end of the rotating gear 8 through a mounting bolt 10. The rotating gear 8 and the mounting ring 9 are coaxially sleeved with the storage box 2. A driving motor is installed on the bottom sliding frame 6, and the driving motor The output end of the drive gear 13 is fixed with the drive gear 13 meshing with the rotating gear 8, and then the drive motor is turned on to rotate the drive gear 13 and mesh with the rotating gear 8 to rotate on the fixed frame 7. Since the limit rod 11 is clamped in the annular groove 12 on the rotating gear 8, and the rotating gear 8 and the mounting ring 9 are coaxially sleeved with the storage box 2, the rotating gear 8 will rotate. At the same time, the mounting ring 9 is coaxially installed at one end of the rotating gear 8 by the mounting bolt 10, so it can also drive the mounting ring 9 to rotate coaxially.

[0051] The intermittent unloading part also includes a push plate 22, which is connected to the intercepting plate 20 through a connecting plate 21, and slides on the outer wall of the storage box 2 through a second return spring 23, and the push plate 22 is abutted against the inner ring side wall of the mounting ring 9 through the second return spring 23. The inner wall of the mounting ring 9 is symmetrically provided with side grooves 24, and arc-shaped chamfers are provided at both ends of the side grooves 24. The push plate 22 is connected to the intercepting plate 20 through a connecting plate 21, and the push plate 22 is abutted against the inner ring side wall of the mounting ring 9 through the second return spring 23. Since the inner wall of the mounting ring 9 is symmetrically provided with side grooves 24, when the mounting ring 9 rotates, the push plate 22 will be pushed into the side groove 24 under the action of the second return spring 23, and then will be separated from the side groove 24 under the action of the arc-shaped chamfer, so that the push plate 22 drives the intercepting plate 20 to extend and retract once in the side hole 19.

[0052] Since the mounting ring 9 is detachable, the mounting ring 9 with a different number of side grooves 24 will be replaced. The symmetrically opened side grooves 24 are a group. Therefore, when the mounting ring 9 rotates one circle, the more groups there are, the more times the intercepting plate 20 can be extended and retracted in the side hole 19.

[0053] When the intercepting plate 20 is retracted into the side hole 19 and no longer blocks the storage fin 301 from moving toward the bottom hole, the width of the bottom hole is the same as the thickness of the storage fin 301, and the storage fin 301 is still pushed by the pushing plate 4 and does not fall off; when the intercepting plate 20 is re-extended into the storage box 2, since the intercepting plate 20 is chamfered on the side facing the storage fin 301, and the side facing the bottom hole is flat, the intercepting plate 20 acts as a partition to separate the storage fin 301 located above the bottom hole, and the pushing plate 4 will no longer push the storage fin 301 located above the bottom hole, and the pushing plate 4 will fall off from the bottom hole.

[0054] Since both the storage fin 301 and the installation fin 302 are provided with slots that are compatible with the clips of the heat exchange metal tube 1, the installation fin 302 will slide down under the guidance of the limit plates 14 on both sides, and the slots will be stuck in the heat exchange metal tube 1. At the same time, the installation fin 302 will also fall on the curved panel 15 and squeeze the trigger button 17, and disconnect the electromagnetic generator 18.

[0055] The heat exchange metal tube 1 is also provided with a tube support portion for expanding the heat exchange metal tube 1 and squeezing and positioning it with the mounting fin 302. The tube support portion includes an electric push rod 28. A circuit system for opening the electric push rod 28 is provided in the metal iron block 25. The descent of the lifting rod 27 is used to connect the circuit system and open the electric push rod 28.

[0056] An electromagnetic generator 18 is fixed on the side of the bottom sliding frame 6 facing the bottom hole, and the trigger button 17 is used to disconnect the electromagnetic generator 18. A metal iron block 25 attracted to the electromagnetic generator 18 is also provided in the heat exchange metal tube 1, and the metal iron block 25 slides in the heat exchange metal tube 1 through a sliding roller 26. A telescopic sliding lifting rod 27 is also provided in the metal iron block 25, and the lifting and lowering of the lifting rod 27 is used to trigger the opening and closing of the pipe support part.

[0057] The lifting rod 27 is made of metal iron. When the electromagnetic generator 18 is not disconnected, the magnetic field generated by the electromagnetic generator 18 always attracts the metal iron block 25 located in the heat exchange metal tube 1 and moves with the supporting tube portion, wherein the supporting tube portion and the bottom hole are located in the same vertical plane; when the electromagnetic generator 18 is disconnected, the lifting rod 27 that originally attracted the iron loses its suction force and falls, and at the same time connects the circuit system and turns on the electric push rod 28, and the electric push rod 28 drives the push rod 30 to retract.

[0058] There are multiple extrusion plates 31, and the multiple extrusion plates 31 are arranged in a circle. A side frame 29 is fixed to the outer wall of the electric push rod 28, and a plurality of fixed cylinders 32 are fixed to the outer wall of the side frame 29. A telescopic rod 33 fixed to the extrusion plate 31 is coaxially slidably disposed on the fixed cylinder 32. A pushing rod 30 is fixed to the output end of the electric push rod 28, and a swinging rod 34 connected to the rotation of the telescopic rod 33 is disposed on the outer wall of the pushing rod 30. Since the swinging rod 34 connected to the rotation of the telescopic rod 33 is disposed on the outer wall of the pushing rod 30, the telescopic rod 33 is driven to move in the fixed cylinder 32, and the extrusion plate 31 is pushed to extrude and expand the section of the heat exchange metal tube 1, and the slot of the metal fin 3 is squeezed to complete the fixation of the fin 302 installed on the heat exchange metal tube 1. At the same time, for the fixation of the installed fin 302, a shrinking slot is used to allow the installed fin 302 to be stuck on the heat exchange metal tube 1, so as to complete the secondary fixation of the installed fin 302.

[0059] The working principle and specific operation steps of the present invention are as follows:

[0060] S1: First, multiple storage fins 301 are placed in the storage box 2, and then the driving device is turned on to drive the storage box 2 to slide horizontally on the heat exchange metal tube 1, wherein the push plate 4 pushes the storage fins 301 toward the bottom hole under the action of the first return spring 5. Since the other ends of the multiple storage fins 301 are blocked by the interception plate 20 at this time, the storage fins 301 cannot reach above the bottom hole at this time;

[0061] S2: Then turn on the driving motor, let the driving motor drive the driving gear 13 to rotate, and mesh the rotating gear 8 to rotate on the fixing frame 7. Since the limit rod 11 is clamped in the annular groove 12 on the rotating gear 8, and the rotating gear 8 and the mounting ring 9 are coaxially sleeved with the storage box 2, the rotating gear 8 will rotate. At the same time, the mounting ring 9 is coaxially mounted on one end of the rotating gear 8 through the mounting bolt 10, so it can also drive the mounting ring 9 to rotate coaxially.

[0062] S3: The push plate 22 is connected to the interception plate 20 through the connecting plate 21, and the push plate 22 is abutted against the inner ring side wall of the mounting ring 9 through the second return spring 23. Since the inner wall of the mounting ring 9 is symmetrically provided with side grooves 24, the push plate 22 is pushed into the side groove 24 under the action of the second return spring 23 when the mounting ring 9 rotates, and then is separated from the side groove 24 under the action of the arc-shaped chamfer, so that the push plate 22 drives the interception plate 20 to extend and retract once in the side hole 19;

[0063] Since the mounting ring 9 is detachable, the mounting ring 9 with different numbers of side grooves 24 will be replaced. The symmetrically arranged side grooves 24 form a group. Therefore, when the mounting ring 9 rotates one circle, the more groups there are, the more times the intercepting plate 20 is extended and retracted in the side hole 19, so the distance between two adjacent mounting fins 302 can be controlled.

[0064] S4: When the intercepting plate 20 is retracted into the side hole 19 and no longer blocks the storage fin 301 from moving toward the bottom hole, the width of the bottom hole is the same as the thickness of the storage fin 301, and the storage fin 301 is still pushed by the push plate 4 and does not fall off; when the intercepting plate 20 is re-extended into the storage box 2, since the intercepting plate 20 has a chamfered corner on the side facing the storage fin 301, and the side facing the bottom hole is a plane, the intercepting plate 20 acts as a partition to separate the storage fin 301 located above the bottom hole, and the push plate 4 no longer pushes the storage fin 301 located above the bottom hole, and the push plate 4 will fall off from the bottom hole;

[0065] S5: Since the storage fin 301 and the installation fin 302 are both provided with slots adapted to the buckle of the heat exchange metal tube 1, the installation fin 302 will slide down under the guidance of the limit plates 14 on both sides, and the slots will be stuck in the heat exchange metal tube 1. At the same time, the installation fin 302 will also fall on the curved plate 15 and squeeze the trigger button 17, and disconnect the electromagnetic generator 18;

[0066] S6: When the electromagnetic generator 18 is not disconnected, the magnetic field generated by the electromagnetic generator 18 always attracts the metal iron block 25 located in the heat exchange metal tube 1, and moves with the tube support portion, wherein the tube support portion and the bottom hole are located in the same vertical plane; when the electromagnetic generator 18 is disconnected, the lifting rod 27 that originally attracted the iron loses its suction force and falls down, and at the same time, the circuit system is connected and the electric push rod 28 is turned on, and the electric push rod 28 drives the push rod 30 to retract;

[0067] S7: Since the outer wall of the push rod 30 is provided with a swing rod 34 rotatably connected to the telescopic rod 33, the telescopic rod 33 will be driven to move in the fixed tube 32, and the extrusion plate 31 will be pushed to squeeze the expansion section of the heat exchange metal tube 1, and squeeze the slot of the metal fin 3, so as to complete the fixation of the fin 302 installed on the heat exchange metal tube 1. At the same time, in order to fix the installed fin 302, a shrinking slot method is used to allow the installed fin 302 to be stuck on the heat exchange metal tube 1, so as to complete the secondary fixation of the installed fin 302.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.

The fin processing and tube threading equipment according to claim 7, characterized in that: The support pipe portion comprises: An electric push rod (28), wherein a circuit system for opening the electric push rod (28) is arranged in the metal iron block (25), and the descent of the lifting rod (27) is used to connect the circuit system and open the electric push rod (28); A squeezing plate (31), wherein the squeezing plates (31) are provided in a plurality and the plurality of squeezing plates (31) are arranged in a circumferential manner, a side frame (29) is fixed to the outer wall of the electric push rod (28), a plurality of fixed cylinders (32) are fixed to the outer wall of the side frame (29), and a telescopic rod (33) fixed to the squeezing plate (31) is coaxially slidably disposed on the fixed cylinder (32); A push rod (30) is fixed to the output end of the electric push rod (28), and a swing rod (34) rotatably connected to the telescopic rod (33) is provided on the outer side wall of the push rod (30).

9. The fin processing and tube threading equipment according to claim 8, characterized in that: The storage fin (301) and the installation fin (302) are both provided with slots that are snap-fitted with the heat exchange metal tube (1).

10. A method for fin processing and tube threading equipment, applied to a fin processing and tube threading equipment as claimed in claim 9, characterized in that: The specific steps are as follows: S1: First, a plurality of storage fins (301) are placed in a storage box (2), and then a driving device is turned on to drive the storage box (2) to slide horizontally on the heat exchange metal tube (1), wherein the push plate (4) pushes the storage fins (301) to move toward the bottom hole under the action of the first return spring (5); S2: Then, the driving motor is turned on, and the driving motor drives the driving gear (13) to rotate, and the rotating gear (8) is meshed and rotated on the fixing frame (7). At the same time, the mounting ring (9) is coaxially mounted on one end of the rotating gear (8) through the mounting bolt (10), so that the mounting ring (9) can also be driven to rotate coaxially; S3: The push plate (22) is connected to the interception plate (20) through the connecting plate (21), and the push plate (22) is abutted against the inner ring side wall of the mounting ring (9) through the second return spring (23). When the mounting ring (9) rotates, the push plate (22) is pushed into the side groove (24) under the action of the second return spring (23), and then separated from the side groove (24) under the action of the arc chamfer, so that the push plate (22) drives the interception plate (20) to expand and contract once in the side hole (19); S4: When the interception plate (20) is retracted into the side hole (19) and no longer blocks the storage fin (301) from moving toward the bottom hole, when the interception plate (20) is re-extended into the storage box (2), the interception plate (20) acts as a partition to separate the storage fin (301) located above the bottom hole; S5: Since both the storage fin (301) and the installation fin (302) are provided with slots adapted to the clips of the heat exchange metal tube (1), the installation fin (302) will slide down under the guidance of the limit plates (14) on both sides, and the slots will be stuck in the heat exchange metal tube (1). At the same time, the installation fin (302) will also fall on the curved plate (15) and press the trigger button (17), thereby disconnecting the electromagnetic generator (18); S6: When the electromagnetic generator (18) is not disconnected, the magnetic field generated by the electromagnetic generator (18) continues to attract the metal iron block (25) located in the heat exchange metal tube (1) and moves with the tube support portion. When the electromagnetic generator (18) is disconnected, the lifting rod (27) that originally attracted the iron loses its suction force and falls down. At the same time, the circuit system is connected and the electric push rod (28) is turned on. The electric push rod (28) drives the push rod (30) to retract. S7: Push the extrusion plate (31) to extrude the expanded section of the heat exchange metal tube (1), and squeeze the slot of the metal fin (3), thereby completing the fixation of the installed fin (302) on the heat exchange metal tube (1). At the same time, the installation fin (302) needs to be fixed by shrinking the slot so that the installation fin (302) is stuck on the heat exchange metal tube (1), thereby completing the secondary fixation of the installation fin (302).
