Description

Technical Field

[0001] The present invention relates to the technical field of fin tube processing, and more particularly to a forming machine for fin tube processing. Background Art

[0002] Finned tubes are heat exchange components. To improve heat transfer efficiency, fins are typically added to the tube surface to increase the tube's outer (or inner) surface area. Currently, the production of finned tubes requires the use of a forming machine, which inserts an aluminum tube into the tube's exterior and then rolls it into shape.

[0003] According to the search, the patent number CN105014333A discloses a roll-formed composite spiral finned tube preparation device and preparation method, including: steel tube feeding, polishing, straightening, unloading, chamfering and other devices; aluminum tube feeding, straightening, unloading, chamfering and other devices; and a rolling device for rolling the steel tube and the aluminum tube into a large-area spiral finned tube, which is a cold extrusion method; also includes a conveying device for transporting steel tubes, aluminum tubes and rolled finned tubes; wherein, the rolling device includes a base, a rolling platform connected to the base through an adjustable support frame, and a rolling mill arranged on the rolling platform drives a rolling cutter group to roll the aluminum tube into spiral fins, providing a roll-formed composite spiral finned tube preparation device to improve the heat exchange area and heat exchange efficiency of the large-area composite spiral finned tube.

[0004] Regarding the related technologies mentioned above, the forming machine in the current existing technology is usually the above-mentioned device. However, if the wall thickness of the aluminum tube is uneven in the circumferential direction during the production process, then during the rolling process, the thicker wall area requires greater pressure to achieve the same deformation as the thinner wall area. During actual rolling, since the pressure is applied evenly, it will cause different degrees of deformation in parts with different wall thicknesses, and thus make the circumferential diameter of the fin inconsistent. In addition, problems such as unstable rolling force and material hardness will also lead to different circumferential diameters. Fin tubes with such problems need to be processed separately, otherwise it will seriously affect the subsequent use effect. Existing forming machines are not convenient for discovering such situations, and direct judgment by the naked eye is not accurate. For this reason, a forming machine for fin tube processing is proposed. Summary of the Invention

[0038] During use, the staff will send the fin tube to be processed through the cleaning module 300 into the interior of the molding machine body 120, open the molding machine body 120, and the molding machine body 120 will process the fin tube. At the same time, the cleaning module 300 will clean the fin tube to keep the outside of the fin tube clean. The fin tube will be rotated and sent out of the molding machine body 120, and the elastic component 250 will press on the fin tube. When the outer surface of the fin tube becomes uneven in thickness, the elastic component 250 will push the drawing component 270 to move, and the drawing component 270 will float up and down on the multi-faceted column 240 to draw a vertical straight line of a certain length. After the molding machine body 120 is processed, the staff observes the straight line on the multi-faceted column 240. If it exceeds the length range, it is uneven. If the fin tube is in qualified state, the staff will reprocess it. When processing the fin tube again, the staff will pull the drawing component 270 outward to separate it from the multi-faceted column 240, then pull the drawing component 270 downward, and then lift the drawing component 270 upward. The drawing component 270 will drive the booster component 280 to rise through the special-shaped rod 260, and the booster component 280 will move on the steering component 230. Subsequently, the drawing component 270 is pushed downward to reset. The drawing component 270 will transmit the steering component 230 through the booster component 280, and the steering component 230 drives the multi-faceted column 240 to turn for the face-changing operation. After the face-changing operation, the drawing component 270 is released to make it contact with the multi-faceted column 240 again, and the elastic component 250 contacts the outer surface of another fin tube to continue the inspection.

[0039] The elastic component 250 includes a square sleeve 251 fixedly connected to the bottom of the support seat 210, the square sleeve 251 is movably connected to a square rod 252 inside, the bottom end of the square rod 252 is movably connected to a ball 253, the top of the square rod 252 is fixedly connected to the bottom of the support seat 210 with a second spring 254, the front end surface of the square sleeve 251 is provided with a second lifting groove, the steering component 230 includes a rotating circular groove opened on the top of the support seat 210, the interior of the rotating circular groove is rotatably connected to a steering disc 231, the polyhedral column 240 is fixedly connected to the top of the steering disc 231, and the steering disc The outer surface of 231 is provided with a plurality of mounting grooves, and the interiors of the plurality of mounting grooves are all movably connected with right-angled trapezoidal blocks 232, and one end of the plurality of right-angled trapezoidal blocks 232 is fixedly connected to the inner wall of the plurality of mounting grooves with a first spring 233. The interior of the rotating circular groove is provided with a plurality of right-angled triangular grooves 234 in an annular shape and at equal distances, and the other ends of the plurality of right-angled trapezoidal blocks 232 are movably connected to the interiors of the plurality of right-angled triangular grooves 234. The steering assembly 230 also includes a conical gear ring 235 fixedly connected to the top of the steering disc 231. The outer surface of the protective cylinder 220 is rotatably connected to an inner rotating rod 236, and the inner rotating rod 236 is fixedly connected to the inner wall of the plurality of mounting grooves. One end of the inner rotating rod 236 is fixedly connected to a bevel gear 237, which meshes with the outer surface of the bevel gear ring 235. The other end of the inner rotating rod 236 is fixedly connected to a ratchet 238. The booster assembly 280 includes a hollow block 281 fixedly connected to the top of the special-shaped rod 260. The inside of the hollow block 281 is movably connected to a ratchet bar 282, which is adapted to the ratchet 238. A plurality of fourth springs 283 are fixedly connected between the ratchet bar 282 and the inner wall of the hollow block 281. The drawing assembly 270 includes a long plate 271 fixedly connected to the outer surface of the special-shaped rod 260. The top of the long plate 271 is connected to the outer surface of the special-shaped rod 260. The end is fixedly connected to a semicircular plate 272, and the interior of the semicircular plate 272 is movably connected to two movable mounting rods 273. A third spring 274 is fixedly connected between the opposite ends of the two movable mounting rods 273 and the semicircular plate 272. The two third springs 274 are respectively located on the outside of the two movable mounting rods 273. The adjacent ends of the two movable mounting rods 273 are movably plugged with metal hexagonal plugs 275. The adjacent ends of the two metal hexagonal plugs 275 are respectively fixedly connected with a drawing pen 278 and a cleaning wipe 277. The drawing pen 278 and the cleaning wipe 277 are both in contact with the outer surface of the multi-faceted column 240.

[0040] The ball 253 will be pressed on the fin tube by the elastic force of the second spring 254. When the outer surface of the fin tube becomes uneven in thickness, the ball 253 will push the square rod 252 to float up and down. At this time, the special-shaped rod 260 drives the long plate 271 and the semicircular plate 272 to move, so that the drawing pen 278 can float up and down on the polygonal column 240, thereby drawing a vertical straight line of a certain length. After the molding machine body 120 is processed, the staff observes the straight line on the polygonal column 240. If it exceeds the length range, it is an unqualified state. The staff will reprocess it later. When processing the fin tube again, the staff pulls out one of the movable mounting rods 273. The movable mounting rod 273 will stretch one of the third springs 274 to separate the drawing pen 278 from the polygonal column 240, and then push the semicircular plate 272 downward, and then lift the semicircular plate 272 upward, so that the cleaning wipe 277 swings to erase the straight line on the polygonal column 240. When the semicircular plate 272 rises, it will drive the hollow block 281 to rise through the special-shaped rod 260. Since the steering disc 231 cannot drive the right-angled trapezoidal block 232 to rotate counterclockwise, the ratchet bar 282 will repeatedly move into the interior of the hollow block 281 when passing the ratchet wheel 238, and then push the semicircular plate 272 downward to reset. At this time, the ratchet bar 282 drives the ratchet wheel 238, and the ratchet wheel 238 drives the bevel gear 237 through the inner rotating rod 236, and the bevel gear 237 will drive The conical gear ring 235 drives the steering disc 231 to rotate, so that the steering disc 231 rotates and drives the right-angled trapezoidal block 232 to rotate out of one of the right-angled triangular grooves 234 and into the other right-angled trapezoidal block 232, thereby allowing the steering disc 231 to drive the polyhedral column 240 to rotate and perform the face-changing operation. After the face-changing operation, the movable mounting rod 273 is released to allow the drawing pen 278 to contact the polyhedral column 240 again, and the ball 253 contacts the outer surface of another fin tube to continue the inspection.

[0041] The drawing component 270 also includes two magnetic blocks 276, which are respectively arranged inside the two movable mounting rods 273. The two magnetic blocks 276 are respectively magnetically connected to the two metal hexagonal plug rods 275. The test module 200 also includes two standard slots 290. The two standard slots 290 are both opened on the outer surface of the multi-faceted column 240. The drawing pen 278 is located between the two standard slots 290. The protective tube 220, the semicircular plate 272 and the long plate 271 are all made of transparent materials.

[0042] Through the magnetic connection between the metal hexagonal plug 275 and the magnetic block 276, the metal hexagonal plug 275 can be pulled outward, and the metal hexagonal plug 275 will be withdrawn from the movable mounting rod 273 and separated from the magnetic block 276, so that the cleaning wipe 277 and the drawing pen 278 can be replaced after a specified time of use. The replacement operation is simple and convenient for the staff to operate. Through the setting of two standard slots 290, as long as the straight line drawn on the polyhedron 240 exceeds the two standard slots 290, it means that the outer surface shape specifications of the fin tube do not meet the requirements, which makes it easier for the staff to make judgments. At the same time, the protective tube 220, the long plate 271 and the semicircular plate 272 are transparent, which makes it easier for the staff to view the polyhedron 240.

[0043] The cleaning module 300 includes two hollow frames 310, both of which are fixedly connected to the top of the base plate 110. A gear ring 320 is rotatably connected between the two hollow frames 310. The inner wall of the gear ring 320 is fixedly connected to an annular brush 330. The opposite sides of the two hollow frames 310 are fixedly connected to annular water pipes 340. The inner walls of the two annular water pipes 340 are fixedly connected to multiple nozzles. The outer surfaces of the two annular water pipes 340 are fixedly connected to liquid supply pipes 350. One end of the two liquid supply pipes 350 is provided with a joint 360. The cleaning module 300 also includes a driving motor 370 fixedly connected to one of the hollow frames 310. The output shaft of the driving motor 370 is fixedly connected to a driving gear 380. The outer surface of the driving gear 380 is meshed with the outer surface of the gear ring 320. The outer surface of one of the hollow frames 310 is fixedly connected to a protective cover 390, which is located outside the driving motor 370.

[0044] Turn on the drive motor 370, which will drive the driving gear 380 to transmit the gear ring 320. The gear ring 320 drives the annular brush 330 to rotate. At this time, the two joints 360 are respectively connected to the external clean water pipe and the detergent pipe. The detergent is first sprayed through the annular water pipe 340 and the nozzle. Then, the rotating annular brush 330 cooperates with the detergent to brush the outer surface of the fin tube. Subsequently, another annular water pipe 340 and the nozzle spray clean water to flush the detergent and impurities on the outer surface of the fin tube, thereby keeping the outside of the fin tube clean.

[0045] The implementation principle of the embodiment of the present invention is as follows: when in use, the staff will send the fin tube to be processed into the interior of the forming machine body 120 through the annular brush 330 and the two annular water pipes 340, open the forming machine body 120, and the forming machine body 120 will process the fin tube, and at the same time turn on the drive motor 370, the drive motor 370 will drive the driving gear 380 to transmit the gear ring 320, and the gear ring 320 drives the annular brush 330 to rotate. At this time, the two joints 360 are respectively connected to the external clean water pipe and the detergent pipe. The detergent is first sprayed out through the annular water pipe 340 and the nozzle, and then the rotating annular brush 330 cooperates with the detergent to brush the outer surface of the fin tube, and then another annular water pipe 340 and the nozzle are used to clean the outer surface of the fin tube. Clean water is sprayed to flush away the cleaning agent and impurities on the outer surface of the fin tube, thereby keeping the outside of the fin tube clean. The processed fin tube will be rotated and sent out of the forming machine body 120, and the ball 253 will be pressed on the fin tube by the elastic force of the second spring 254. When the outer surface of the fin tube becomes uneven in thickness, the ball 253 will push the square rod 252 to float up and down. At this time, the special-shaped rod 260 drives the long plate 271 and the semicircular plate 272 to move, so that the drawing pen 278 floats up and down on the multi-faceted column 240, thereby drawing a vertical straight line of a certain length. After the forming machine body 120 is processed, the staff observes the straight line on the multi-faceted column 240. If it exceeds the length range, it is unqualified, and the staff will conduct subsequent When reprocessing, when processing the fin tube again, the staff pulls out one of the movable mounting rods 273, and the movable mounting rod 273 will stretch one of the third springs 274 to separate the drawing pen 278 from the polygonal column 240, and then push the semicircular plate 272 downward, and then lift the semicircular plate 272 upward, so that the cleaning wipe 277 swings to erase the straight line on the polygonal column 240. When the semicircular plate 272 rises, it will drive the hollow block 281 to rise through the special-shaped rod 260. Since the steering disc 231 cannot drive the right-angled trapezoidal block 232 to rotate counterclockwise, the ratchet bar 282 will repeatedly move towards the inside of the hollow block 281 when passing the ratchet 238. Subsequently, the semicircular plate 272 is pushed downward to reset. At this time, the ratchet The rod 282 drives the ratchet 238, and the ratchet 238 drives the bevel gear 237 through the inner rotating rod 236. The bevel gear 237 will drive the bevel gear ring 235 to drive the steering disc 231 to rotate, so that the steering disc 231 rotates and drives the right-angled trapezoidal block 232 to rotate out of one of the right-angled triangular grooves 234 and into the other right-angled trapezoidal block 232, so that the steering disc 231 drives the multi-faceted column 240 to turn and perform the face-changing operation. After the face-changing operation, the movable mounting rod 273 is released to allow the drawing pen 278 to contact the multi-faceted column 240 again, and the ball 253 contacts the outer surface of another fin tube to continue the inspection. Through the magnetic connection between the metal hexagonal plug rod 275 and the magnetic block 276, the metal hexagonal plug rod 275 is pulled outward,The metal hexagonal insert 275 will be withdrawn from the movable mounting rod 273 and separated from the magnetic block 276, allowing the cleaning wipe 277 and drawing pen 278 to be replaced after a specified period of use. The replacement operation is simple and convenient for staff. The two standard slots 290 are set so that as long as the straight line drawn on the polyhedron 240 exceeds the two standard slots 290, it means that the outer surface shape of the fin tube does not meet the requirements, thus facilitating staff judgment. At the same time, the transparent setting of the protective tube 220, the long plate 271, and the semicircular plate 272 further facilitates staff to inspect the polyhedron 240.

[0046] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
