Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger production, in particular to a manufacturing device for seamless finned tubes of a copper alloy heat exchanger. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements, and it is an industrial application of convective heat transfer and heat conduction;

[0003] In the prior art, there are many materials for heat exchangers, among which there are heat exchangers made of practical copper alloy materials. In the process of manufacturing a heat exchanger made of copper alloy materials, the seamless finned tubes need to be manufactured by high-frequency welding process. In the process of high-frequency welding of the existing seamless finned tubes, the fixation between the seamless finned tubes and the end plates is not stable enough, which easily leads to unstable connection during the welding process. After the upper half of the seamless finned tubes and the end plates are welded, it is necessary to turn them over to weld the lower half. During the turning process, it is easy to cause deviation between the seamless finned tubes and the end plates, resulting in problems with the solder joints. Therefore, we propose a manufacturing device for seamless finned tubes of a copper alloy heat exchanger. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art. There are many materials for heat exchangers, among which there are heat exchangers made of practical copper alloy materials. In the process of manufacturing a heat exchanger made of copper alloy materials, the seamless finned tubes need to be manufactured by high-frequency welding process. In the process of high-frequency welding of the existing seamless finned tubes, the fixation between the seamless finned tubes and the end plates is not stable enough, which easily leads to unstable connection during the welding process. After the upper half of the seamless finned tubes and the end plates are welded, it is necessary to turn them over to weld the lower half. During the turning process, it is easy to cause deviation between the seamless finned tubes and the end plates, resulting in problems with the solder joints.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A manufacturing device for seamless finned tubes of a copper alloy heat exchanger, including a manufacturing table with a square groove penetrating through the top. At the center of the top of the manufacturing table, a rectangular frame is installed. On the front and back of the frame, rotating shafts in the shape of cylinders and rotatably connected to the manufacturing table are installed. Then, lower fixing frames are symmetrically installed near the bottom inside the frame. Subsequently, upper fixing frames are correspondingly installed on the tops of the lower fixing frames. And on the opposite sides of the lower fixing frames and the upper fixing frames, semi-circular fixing grooves are provided. Inside the frame and symmetrically installed at the bottom of the front and back, lower clamping plates are installed. Then, upper clamping plates are correspondingly installed above the lower clamping plates.

[0007] As a preferred solution of the present utility model, a square protective box is installed on the front of the manufacturing table. Then, a driving motor is installed inside the protective box. The output end of the driving motor is fixedly connected to the rotating shaft.

Then, the output ends of electric push rods are inserted into the limiting holes. The fixed ends of the electric push rods are fixedly connected to the manufacturing table.

[0009] As a preferred solution of the present utility model, bumps are installed on both sides of the upper fixing frame. Then, sliding grooves are correspondingly provided on both sides of the frame around the bumps. The bumps are slidably connected to the sliding grooves.

[0010] As a preferred solution of the present utility model, fixing blocks are correspondingly installed on the front of the sliding grooves and at the top of the frame. Then, a first elastic plug is installed inside the fixing block and extends to the back. A lock block is installed on the periphery of the back of the first elastic plug.

[0024] As Figures 1-3 shown, the present utility model provides a technical solution: a manufacturing device for seamless finned tubes of a copper alloy heat exchanger, including a manufacturing table 1 with a square groove penetrating through the top. At the center of the top of the manufacturing table 1, a rectangular frame 2 is installed. On the front and back of the frame 2, rotating shafts 3 that are cylindrical and rotatably connected to the manufacturing table 1 are installed, facilitating the rotation of the frame 2. Then, lower fixing frames 4 are symmetrically installed near the bottom inside the frame 2. Subsequently, upper fixing frames 5 are correspondingly installed on the tops of the lower fixing frames 4. And on the opposite side surfaces of the lower fixing frames 4 and the upper fixing frames 5, semicircular fixing grooves 6 are opened. Inside the frame 2 and symmetrically installed at the bottom of the front and back, lower clamping plates 7 are installed. Then, upper clamping plates 8 are correspondingly installed above the lower clamping plates 7.

[0025] Embodiment 2

[0026] As Figures 1-3 shown, a square protection box 11 is installed on the front of the manufacturing table 1. Then, a driving motor 12 is installed inside the protection box 11. The output end of the driving motor 12 is fixedly connected to the rotating shaft 3. By the driving motor 12, the rotating shaft 3 can be driven to rotate, so as to flip the seamless finned tube and facilitate its processing.

[0027] On both the left and right sides of the frame 2, two limiting holes 21 are symmetrically opened. Then, the output ends of electric push rods 22 are inserted into the limiting holes 21. The fixed ends of the electric push rods 22 are fixedly connected to the manufacturing table 1. By inserting the output ends of the electric push rods 22 into the limiting holes 21, the frame 2 can be fixed, making the high-frequency welding more stable.

[0028] Both sides of the upper fixing frame 5 are provided with bumps 51. Further, sliding grooves 52 are correspondingly opened on both sides of the frame 2 around the bumps 51. The bumps 51 are slidably connected to the sliding grooves 52. By sliding the bumps 51 in the sliding grooves 52, it is convenient to take out the upper fixing frame 5, thus facilitating the placement and removal of the seamless finned tube.

[0029] Fixing blocks 53 are correspondingly installed on the front of the sliding grooves 52 and at the top of the frame 2. Further, a first elastic plug 54 is installed inside the fixing block 53 and extends to the back. A locking block 55 is installed on the periphery of the back of the first elastic plug 54. The first elastic plug 54 is inserted into the locking block 55. The bumps 51 can be fixed by the first elastic plug 54 and the locking block 55, thus ensuring the stability of welding.

[0030] Three L-shaped connecting blocks 81 are equidistantly installed on the top of the upper clamping plate 8. Further, cylindrical second elastic plugs 82 are installed at the ends of the connecting blocks 81 far from the upper clamping plate 8. Then, limiting grooves 83 are correspondingly opened on the top of the frame 2 around the bottoms of the second elastic plugs 82.

[0031] Working process of the present utility model: When manufacturing a seamless finned tube using a copper alloy heat exchanger seamless finned tube manufacturing device, first, pull the upper clamping plate 8, place the end plate on the top of the lower clamping plate 7. After placement, release the upper clamping plate 8. The second elastic plugs 82 rebound in the limiting grooves 83 to drive the connecting blocks 81 and the upper clamping plate 8 to clamp the end plate. After clamping the end plates at both ends, place the seamless finned tube in the fixing grooves 6 on the lower fixing frame 4. After all are placed, take out the upper fixing frame 5, align the bumps 51 at both ends with the sliding grooves 52, then press the first elastic plug 54 to make the bumps 51 slide into the sliding grooves 52. The upper fixing frame 5 and the lower fixing frame 4 are combined. Then release the first elastic plug 54, and it rebounds to insert into the locking block 55 to limit the bumps 51. After completion, the staff can weld the connection part. After the upper half is welded, control the output end of the electric push rod 22 to retract from the limiting hole 21. Then drive the rotating shaft 3 to rotate through the drive motor 12, drive the frame 2 to flip on the manufacturing table 1. After flipping is completed, the output end of the electric push rod 22 resets, and the staff continues to weld. The present utility model can effectively ensure the stability of the seamless finned tube during the manufacturing process through the design, thus making the manufacturing process smoother.
