Description

Technical Field

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

[0002] Finned tube is a kind of heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency. For such a heat exchange tube, the current finned tube production requires the use of a forming machine, which is to set an aluminum tube on the outside of the main tube, and then put it into the forming machine for rolling and forming.

[0003] According to the search, the patent with patent number CN105014333A discloses a preparation device and method for rolled composite spiral finned tubes, including: devices for feeding, polishing, straightening, unloading, chamfering, etc. for steel tubes; devices for feeding, straightening, unloading, chamfering, etc. for processing aluminum tubes; and a rolling device for composite rolling of steel tubes and aluminum tubes into large-area spiral finned tubes, which rolling device is a cold extrusion method; and 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, and provides a preparation device for rolled composite spiral finned tubes to improve the heat exchange area and heat exchange efficiency of large-area composite spiral finned tubes.

[0004] Regarding the above-mentioned related technologies, the molding 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 requires greater pressure to achieve the same deformation as the thinner wall. During actual rolling, since the pressure is applied evenly, it will cause different degrees of deformation in different parts of the wall thickness, and then make the circumferential diameter of the fin inconsistent. Not only that, the unstable rolling force and material hardness and other problems 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. The existing molding machine is not convenient for discovering such situations, and direct judgment by the naked eye is not accurate.

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. Qualified state, the staff will reprocess it later. 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 to perform 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.

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, and a ratchet bar 282 is movably connected inside the hollow block 281. The ratchet bar 282 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, and the top of the long plate 271 is connected to the outer surface of the special-shaped rod 260. A semicircular plate 272 is fixedly connected to the end, and two movable mounting rods 273 are movably connected inside the semicircular plate 272.

The two third springs 274 are respectively located on the outside of the two movable mounting rods 273. A metal hexagonal plug 275 is movably inserted at the adjacent ends of the two movable mounting rods 273. A drawing pen 278 and a cleaning wipe 277 are respectively fixedly connected at the adjacent ends of the two metal hexagonal plugs 275. The drawing pen 278 and the cleaning wipe 277 are both in contact with the outer surface of the multi-faceted column 240.

[0025] 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 multi-faceted 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 multi-faceted column 240. If it exceeds the length range, it is an unqualified state. The staff will reprocess it later. When the fin tube is processed again, the staff pulls one of the movable mounting rods 273 outward, and the movable mounting rod 273 will stretch one of the third springs 274 to separate the drawing pen 278 from the multi-faceted 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 multi-faceted 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 inside 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 enter 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 detection.

[0026] 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.

[0027] Through the magnetic connection between the metal hexagonal plug rod 275 and the magnetic block 276, when the metal hexagonal plug rod 275 is pulled outward, the metal hexagonal plug rod 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 grooves 290, as long as the straight line drawn on the multi-faceted column 240 exceeds the two standard grooves 290, it means that the outer surface shape specifications of the fin tube do not meet the requirements, which is convenient for the staff to make judgments. At the same time, the protective tube 220, the long plate 271 and the semicircular plate 272 are transparently set to make it easier for the staff to view the multi-faceted column 240.

[0029] Turn on the drive motor 370, which will drive the driving gear 380 to drive 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. 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.

[0030] 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 molding machine body 120 through the annular brush 330 and the two annular water pipes 340, and open the molding machine body 120, the molding 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 drive 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 out through the annular water pipe 340 and the nozzle, and then the rotating annular brush 330 cooperates with the detergent to scrub 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, so as to keep the outside of the fin tube clean. The processed fin tube will be rotated and sent out of the molding 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 is 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, so as 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 unqualified. The staff will conduct subsequent When reprocessing 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 multifaceted 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 multifaceted 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 hollow block 281 when passing the ratchet wheel 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 to drive the right-angled trapezoidal block 232 to rotate out of one of the right-angled triangular grooves 234 and enter another right-angled trapezoidal block 232, so that the steering disc 231 drives the multi-faceted column 240 to turn to 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 detection. 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 plug rod 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 grooves 290, as long as the straight line drawn on the multi-faceted column 240 exceeds the two standard grooves 290, it can represent that the outer surface shape specification of the fin tube does not meet the requirements, so as to facilitate the staff to judge. 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 multi-faceted column 240.

[0031] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope 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 protection scope of the present invention.
