A belt 35 is tightly mounted between each set of two pulleys 34. A plurality of protrusions 37 are provided on each belt 35. Each protrusion 37 is connected to a mounting rod 38. A fixing plate 39 is connected between each set of two mounting rods 38. A feeding seat 40 is provided in the middle of the fixing plate 39. A second motor 36 is installed at the rear end of the right side of the feeding platform 1. One end of the output shaft of the second motor 36 is connected to one of the rotating rods 33. Next, first, start the first motor 5 on the first mounting plate 2 to drive the rotating column 3 and the fixed cylinder 4 to rotate as a whole, and rotate the clamping ring 19 to the two ends of the fin tube on the storage structure. At this time, start the cylinder 23 on the movable plate 11 to drive the movable frame 24 to move toward the movable plate 11, thereby driving the through rod 25 to squeeze the wall of the extrusion groove 27, pulling the two clamping rings 19 to press against the corresponding fin tube ends, and the limiting sleeve 20 of the clamping ring 19 is put on the fin tube for limiting, so as to avoid the clamping ring 19 from being insufficiently clamped during the loading process. In order to solve the problem of the fin tube falling off, after the fin tube is clamped, the first motor 5 is started to drive the rotating column 3 to rotate, and the clamped fin tube to be stamped is loaded onto the top of the lower stamping seat 8. At this time, the electric push rod in the corresponding inner groove 16 is started to drive the end block 17 to move, so as to drive one end of the driving rod 13 to slide in the corresponding driving groove 15. The driving rod 13 squeezes the groove wall of the driving groove 15 to push the corresponding fin tube down to the lower stamping seat 8 for stamping. At the same time, a stamping piece directly below the lower stamping seat 8 is pressed. The formed finned tubes are synchronously moved down to the corresponding feeding seat 40, the corresponding clamping ring 19 is loosened, and the stamped finned tubes are unloaded onto the feeding seat 40. In this way, when the formed finned tubes are unloaded, the finned tubes to be stamped can be synchronously driven to be loaded into the lower stamping seat 8 for stamping, so that the unloading time of the finned tubes is fully utilized, which greatly improves the work efficiency. After the formed finned tubes are unloaded, the second motor 36 can be started to drive the rotating rod 33, the pulley 34 and the belt 35 to rotate as a whole, so as to automatically feed the formed finned tubes.

[0039] See also Figure 2 The storage structure includes two second mounting plates 29 fastened by bolts to the feeding platform 1 near the front side. A storage frame 30 is provided on the top of the second mounting plate 29. The storage frame 30 is tilted downward near the first mounting plate 2. The lower end of the storage frame 30 is connected to the end plate 31. A baffle 32 is connected to the edge of the end plate 31 near the first mounting plate 2. The finned tubes to be stamped are stored in the storage frame 30. Since the storage frame 30 is tilted, not only can the finned tubes be stored, but also after the finned tubes are clamped and loaded on the end plate 31, the finned tubes stored on the storage frame 30 can automatically roll to the end plate 31, which is convenient for loading the next finned tube.

[0040] See also Figure 4-Figure 8 The upper stamping structure includes a third mounting plate 41 mounted on the top of the two first mounting plates 2, a hydraulic cylinder 42 is provided on the third mounting plate 41, an upper stamping seat 43 is installed on the bottom end of the output shaft of the hydraulic cylinder 42, and an anti-deformation structure is provided on the third mounting plate 41;

[0041] The anti-deformation structure includes two anti-deformation rods 44 that are movable through the middle of the left and right sides of the third mounting plate 41. A sleeve plate 46 is fixedly mounted on one end of the anti-deformation rod 44 that passes through the third mounting plate 41. Two telescopic rods 45 are connected between the sleeve plate 46 and the third mounting plate 41. A transmission structure is provided between the anti-deformation rod 44 and the upper punching seat 43.

[0042] The transmission structure includes a swivel 47 rotatably arranged on the third mounting plate 41, the swivel 47 is movably sleeved on the anti-deformation rod 44, the swivel 47 is fixedly inserted into the insertion rod 48, the anti-deformation rod 44 is provided with a spiral groove 51, one end of the insertion rod 48 is slidably set in the spiral groove 51, a gear is fixedly sleeved on the swivel 47, and a penetration bar 50 is connected to both ends of the upper punch seat 43. The penetration bar 50 movably passes through one end of the third mounting plate 41 and is connected to the transmission bar 49. The teeth on the transmission bar 49 are meshed with the gear. When the fin tube moves down to the lower punch seat 8, the fin tube starts to move. The dynamic hydraulic cylinder 42 drives the upper punch seat 43 to move downward. During the downward movement of the upper punch seat 43, the transmission bar 49 and the gear drive the swivel 47 to rotate. The swivel 47 drives one end of the insertion rod 48 to slide in the spiral groove 51. The one end of the insertion rod 48 squeezes the groove wall of the spiral groove 51 to automatically push the anti-deformation rod 44 into the fin tank on the lower punch seat 8. The anti-deformation rod 44 is pressed against the inner wall of the fin tube, so that when the upper punch seat 43 moves down to the lower punch seat 8 to stamp the fin tube, the deformation of the inner wall of the fin tube is avoided, thereby improving the quality of the stamping work.

[0043] The implementation principle of a stamping and forming device for high-efficiency fin tubes in an embodiment of the present invention is as follows: first, the fin tubes to be stamped are stored in the storage frame 30. When the storage frame 30 is tilted, the fin tubes stored in this way can be rolled onto the end plate 31 in sequence on the storage frame 30. Then, the first motor 5 on the first mounting plate 2 is started to drive the rotating column 3 and the fixed cylinder 4 to rotate as a whole, and the clamping ring 19 is rotated to the two ends of the fin tube on the end plate 31. At this time, the cylinder 23 on the movable plate 11 is started to drive the movable frame 24 to move toward the movable plate 11, thereby driving the through rod 25 to squeeze the wall of the extrusion groove 27, pulling the two clamping rings 19 to move. The ring 19 is pressed against the end of the corresponding finned tube, and the upper limit sleeve 20 on the clamping ring 19 is put on the finned tube for limiting, so as to avoid the problem of the finned tube falling off due to the clamping ring 19 not being clamped firmly enough during the loading process. After the finned tube is clamped, the first motor 5 is started to drive the rotating column 3 to rotate, and the clamped finned tube to be stamped is loaded onto the top of the lower stamping seat 8. At this time, the electric push rod in the corresponding inner groove 16 is started to drive the end block 17 to move, so as to drive one end of the driving rod 13 to slide in the corresponding driving groove 15, and the corresponding finned tube is pushed down to the lower part by squeezing the groove wall of the driving groove 15 by the driving rod 13. In the stamping seat 8, at the same time, a stamped fin tube just below the lower stamping seat 8 is synchronously moved down to the corresponding feeding seat 40, and the corresponding clamping ring 19 is loosened to unload the stamped fin tube onto the feeding seat 40. In this way, when the formed fin tube is unloaded, the fin tube to be stamped can be synchronously driven to be loaded into the lower stamping seat 8 for stamping, so that the unloading time of the fin tube is fully utilized, which greatly improves the work efficiency. After the formed fin tube is unloaded, the second motor 36 can be started to drive the rotating rod 33, the pulley 34 and the belt 35 to rotate as a whole, and the formed fin tube is automatically fed. When pressing, the hydraulic cylinder 42 is started to drive the upper punch seat 43 to move downward. During the downward movement of the upper punch seat 43, the transmission bar 49 and the gear drive the swivel 47 to rotate. The swivel 47 drives one end of the insertion rod 48 to slide in the spiral groove 51. The one end of the insertion rod 48 is squeezed against the groove wall of the spiral groove 51 to automatically push the anti-deformation rod 44 into the fin tank on the lower punch seat 8. The anti-deformation rod 44 is pressed against the inner wall of the fin tube, so that when the upper punch seat 43 moves down to the lower punch seat 8 to punch the fin tube, the deformation of the inner wall of the fin tube is avoided, thereby improving the quality of the stamping work, thereby realizing the stamping forming of the fin tube.

[0044] 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.
