A limiting mechanism 7 is provided on the outer wall of the rod 2, the upper surface of the base 1 is fittedly connected to the lower die base 8, and the outer walls on both sides of the lower die base 8 are fixed with a clamping sleeve 9, and support rods 10 are fixedly installed at both ends of the upper surface of the base 1, and a top plate 11 is fixedly installed on the upper end of the support rod 10, and a cylinder 12 is fixedly provided in the middle of the upper surface of the top plate 11, and the end of the output shaft of the cylinder 12 is fixedly connected to a transmission plate 13, and both ends of the transmission plate 13 are fixed with sleeves 14, and the lower surface of the transmission plate 13 is fittedly connected to the upper die base 15, and a clamping column 16 is fixed at both ends of the upper surface of the upper die base 15, and a positioning bolt 17 is provided on the outer wall of the upper end of the clamping column 16.

[0025] The cross-section of the base 1 is set to be an "E" shape, and the base 1 and the adjustment rod 2 are rotatably connected, which makes it convenient for the user to rotate the adjustment rod 2 and improve the stability of the base 1.

[0026] The positioning plate 4 and the knob 5 are threaded, and the knob 5 and the tooth plate 6 are rotatable, and the tooth plate 6 and the base 1 form a sliding structure, which makes it convenient for the user to rotate the knob 5 so that the knob 5 moves vertically relative to the positioning plate 4, thereby driving the tooth plate 6 to move vertically in contact with the base 1.

[0027] The tooth plate 6 is meshed with the gear 3, so that the tooth plate 6 can move to mesh with the gear 3, thereby limiting the adjustment rod 2 and preventing the adjustment rod 2 from becoming loose when the device is in use.

[0028] The limiting mechanism 7 includes a sleeve 701 and a limiting frame 702, and the sleeve 701 is sleeved on the outer wall of the adjusting rod 2, and the upper surface of the sleeve 701 is fixedly connected to the limiting frame 702, so that the lower mold base 8 and the base 1 are in a relatively stable state through the limiting mechanism 7.

[0029] The sleeve 701 is threadedly connected to the adjusting rod 2, and the directions of the threads set on the outer walls of the sleeve 701 and the adjusting rod 2 are symmetrically distributed about the longitudinal center axis of the base 1. The limit frame 702 is slidably set with the base 1 and the sleeve 9 respectively, so that the user can rotate the adjusting rod 2 to make the sleeve 701 move toward or oppositely along the adjusting rod 2 at the same time, thereby driving the limit frame 702 to move, so that the limit frame 702 can be inserted into or disengaged from the sleeve 9.

[0030] The support rod 10 and the sleeve 14 are slidably connected, so that when the user starts the cylinder 12 to close the upper mold base 15, the transmission plate 13 drives the sleeve 14 to slide relative to the support rod 10, thereby allowing the upper mold base 15 to move stably.

[0031] The clamping column 16 and the positioning bolt 17 are threaded, and the positioning bolt 17 is fitted to the transmission plate 13 , so that the user can rotate the positioning bolt 17 to separate the clamping column 16 and the transmission plate 13 , thereby facilitating the user to replace the upper mold base 15 .

[0032] Working principle: When using the fin stamping die, first Figure 1-5As shown, the user places the fin raw material on the lower die base 8, and then the user starts the cylinder 12. Next, the cylinder 12 drives the transmission plate 13 to move downward, so that the upper die base 15 moves downward, and as the transmission plate 13 moves, the transmission plate 13 drives the sleeve 14 to slide relative to the support rod 10, so that the upper die base 15 and the lower die base 8 are combined to perform the fin stamping process. When the die base needs to be replaced according to demand, the user starts the cylinder 12 to drive the upper die base 15 to move up and reset, and then the user rotates the positioning bolt 17 to disengage the positioning bolt 17. The clamping column 16, then the user moves the upper die base 15 so that the upper die base 15 is separated from the transmission plate 13, and at the same time, the upper die base 15 drives the clamping column 16 to separate from the transmission plate 13, thereby removing the old upper die base 15, and then the user moves the new upper die base 15 to fit the transmission plate 13, and at the same time, the new upper die base 15 drives the clamping column 16 to be inserted into the transmission plate 13, and then the user puts the positioning bolt 17 on the clamping column 16 and tightens the positioning bolt 17. At this time, the positioning bolt 17 fits the transmission plate 13, thereby completing the replacement of the upper die base 15. After that, the user rotates the knob 5 so that the knob 5 moves up relative to the positioning plate 4, and then the knob 5 drives the tooth plate 6 to slide up relative to the base 1 so that the tooth plate 6 disengages from the gear 3, and then the user rotates the adjusting rod 2, and then the sleeve 701 moves in the opposite direction along the adjusting rod 2 at the same time, and then the sleeve 701 drives the limit frame 702 to slide relative to the base 1 so that the limit frame 702 disengages from the sleeve 9, and then the user moves the old lower die base 8 away from the device, thereby completing the disassembly of the old lower die base 8, and then the user places the new lower die base 8 on the base 1, and then the user rotates the adjusting rod 2 in the opposite direction so that the sleeve 701 moves in the opposite direction at the same time, and then the sleeve 701 drives the limit frame 702 to move so that the limit frame 702 is inserted into the sleeve 9 on the new lower die base 8, and then the user rotates the knob 5 in the opposite direction so that the tooth plate 6 moves down, and then the tooth plate 6 moves to engage with the gear 3, thereby limiting the adjusting rod 2 and completing the replacement of the lower die base 8, so the device is convenient for replacing the stamping die base according to needs, thereby facilitating the device to process fins of different models, thereby improving the practicality of the device.
