DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5, the present utility model provides a technical solution: a flanging structure of an air conditioner fin mold, including a mold frame 1, a lower template 2, an upper hydraulic rod 3, an upper template 4, a guide post 5, a lower mounting hole 6, a support hydraulic rod 7, a flanging female die 8, a support plate 9, an adjusting threaded rod 10, a movable column 11, a top mounting hole 12, a stabilizing block 13, a track groove 14, a flanging male die 15 and a side locking bolt 16. The lower template 2 is installed at the bottom of the mold frame 1, the upper hydraulic rod 3 is fixed at the top of the mold frame 1, the upper template 4 is installed at the bottom end of the upper hydraulic rod 3, the guide post 5 is installed on the lower template 2, and the guide post 5 penetrates through the upper template 4. The lower mounting hole 6 is opened on the bottom of the mold frame 1 and the lower template 2, and the support hydraulic rod 7 is fixedly installed in the lower mounting hole 6. The top end of the support hydraulic rod 7 is fixed with the flanging female die 8. The support plate 9 is fixed on the top surface of the upper template 4. The adjusting threaded rod 10 is rotatably installed in the middle of the support plate 9 through a bearing seat. The bottom end of the adjusting threaded rod 10 is connected to the inner wall of the hole opened at the top of the movable column 11. The movable column 11 is arranged in the top mounting hole 12. The top mounting hole 12 is opened on the upper template 4. The stabilizing block 13 is fixed on the outer wall of the movable column 11. The stabilizing block 13 fits with the inner wall of the track groove 14. The track groove 14 is opened on the inner wall of the top mounting hole 12. The bottom end of the movable column 11 is fixed with the flanging male die 15.

[0024] In this example, the outer wall of the flanging female die 8 fits with the inner wall of the lower mounting hole 6. The diameter of the lower mounting hole 6 is larger than the diameter of the movable column 11. The above structural design ensures the stability of the flanging female die 8 during adjustment and static use, and at the same time ensures that the movable column 11 can smoothly move vertically into the lower mounting hole 6.

[0025] The front view shape of the support plate 9 is "冂"-shaped, and the top view width of the support plate 9 is not less than half of the top diameter of the adjusting threaded rod 10. The above structural design makes the support plate 9 have sufficient structural strength to stably install and support the adjusting threaded rod 10.

[0026] The adjusting threaded rod 10 is threadedly connected to the movable column 11, and the movable column 11 is slidably connected to the top mounting hole 12. The above structural design enables the adjusting threaded rod 10 to stably drive the movable column 11 to move along the top mounting hole 12 when rotating by using the threaded connection relationship.

[0027] The center of the top mounting hole 12 and the center of the lower mounting hole 6 are on the same vertical line. The top mounting hole 12 and the lower mounting hole 6 are equally spaced on both sides of the upper template 4 and the lower template 2. The above structural design enables the installation structure in the top mounting hole 12 to be stably aligned with the installation structure in the lower mounting hole 6, ensuring that the flanging female die 8 and the flanging male die 15 can stably cooperate for flanging.

[0028] The stabilizing block 13 and the track groove 14 are slidably connected. The stabilizing block 13 and the track groove 14 are symmetrically distributed about the center of the movable column 11. The above structural design can prevent the movable column 11 from rotating, so that the movable column 11 can only slide vertically along the track groove 14 with the stabilizing block 13.

[0029] A side locking bolt 16 is threadedly installed on the side of the upper template 4, and the center of the side locking bolt 16 is on the same vertical plane as the center of the adjusting threaded rod 10. The above structural design enables the side locking bolt 16 to stably squeeze the movable column 11 connected to the bottom of the adjusting threaded rod 10 to fix it.

[0030] The side locking bolt 16 is distributed vertically to the adjusting threaded rod 10, and the diameter of the side locking bolt 16 is not less than 1 / 3 of the diameter of the adjusting threaded rod 10. The above structural design enables the side locking bolt 16 to stably squeeze the movable column 11 connected to the bottom of the adjusting threaded rod 10, thereby fixing the relative position of the movable column 11 and the adjusting threaded rod 10.

[0031] Working principle: When using this device, according to the requirements of the fin flanging, select the appropriate number of flanging punches 15 to extend out of the bottom surface of the upper template 4. The initial state is as follows: Figure 2 As shown, when the flanging punch 15 needs to be stored away from use, the adjusting threaded rod 10 is rotated in the opposite direction. The adjusting threaded rod 10 drives the movable column 11 to slide vertically upward along the track groove 14 with the stabilizing block 13 by means of the threaded connection relationship. The movable column 11 moves the flanging punch 15 upward and is stored in the top mounting hole 12, and will not contact the flanging die 8 during the processing.

[0032] Then place the fin on the lower template 2, and rotate the adjusting threaded rod 10 above the position where the vertical hole on the edge of the fin is opened in the forward direction. The adjusting threaded rod 10 rotates to drive the movable column 11 to move the flanging punch 15 vertically downward to an appropriate distance. Stop rotating the adjusting threaded rod 10, and rotate the side locking bolt 16 to squeeze the movable column 11 to fix it, and adaptively control the shortening of the supporting hydraulic rod 7 to adjust the working height of the flanging die 8. Then, the upper hydraulic rod 3 can be started to extend and push the upper template 4 to move down and contact the fin. The flanging punch 15 moves down synchronously with the upper template 4. The bottom end of the flanging punch 15 squeezes the vertical hole on the edge of the fin, and presses the fin structure around the vertical hole into the flanging die 8, pressing the vertical hole on the edge of the fin into a hole with a certain height of outward turn to complete the flanging process. This is the working principle of the flanging structure of the air-conditioning fin mold.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
