[0023] 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.

[0024] Example 1

[0025] like Figure 1 As shown;

[0026] A fan production bending device comprises a base plate 1.

[0027] In this embodiment: the existing disclosure (announcement) number: CN213559259U discloses a bending device for fan production. In order to solve the existing problems existing in this prior art, as disclosed in the background technology above, "the existing bending devices are all bent by stamping during the bending process, but in the process of stamping, since the force points of the plate are all concentrated at the bending point, this easily leads to fracture at the bending point." In terms of combined use, this problem is obviously a problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, a bending component 2 and a buffer component 3 are added to this application document.

[0028] More specifically:

[0029] like Figures 1 to 4 As shown:

[0030] In combination with the above content: it also includes a bending component 2 arranged on the surface of the bottom plate 1;

[0031] The bending assembly 2 includes a vertical plate 21 fixedly connected to the surface of the base plate 1, and the end of the vertical plate 21 away from the base plate 1 is fixedly connected to the supporting plate 22, and the two sides of the supporting plate 22 are symmetrically fixedly connected with columns 23, and the end of the column 23 away from the supporting plate 22 is fixedly connected to the mounting plate 24, and a cylinder 25 is installed on the surface of the mounting plate 24. The extension axis of the cylinder 25 passes through the surface of the mounting plate 24 and is fixedly connected to the fixed plate 26 arranged below the mounting plate 24, and a bending block 27 is installed on the surface of the fixed plate 26. The surface of the supporting plate 22 is fixedly connected with a bending trough 28 adapted to the bending block 27.

[0032] In this embodiment: because the surface of the bottom plate 1 is provided with a bearing plate 22 through the vertical plate 21, and the surface of the bearing plate 22 is provided with a bending groove 28, the staff can place the part of the fan that needs to be bent above the bending groove 28, and by starting the cylinder 25, the cylinder 25 pushes the fixed plate 26 and the bending block 27 to move, and the fan is bent through the cooperation of the bending block 27 and the bending groove 28. With this design, the fan can be easily bent.

[0033] Going further:

[0034] In an optional embodiment, reinforcement plates 29 are fixedly connected to both sides of the bending trough 28 , and the reinforcement plates 29 are fixedly connected to the surface of the bearing plate 22 .

[0035] In this embodiment, since the reinforcing plate 29 is provided, during the bending process of the fan, the bending trough 28 is reinforced by the provided reinforcing plate 29 to prevent the bending portion from deviating.

[0036] Going further:

[0037] In an optional embodiment, it further includes a buffer component 3 arranged on the surface of the bottom plate 1;

[0038] The buffer assembly 3 includes a support plate 31 fixedly connected to both sides of the vertical plate 21, and the end of the support plate 31 away from the base plate 1 is rotatably connected to the buffer plate 32, the surface of the buffer plate 32 is fixedly connected to the positioning frame 33, and the surface of the positioning frame 33 is threadedly connected to two threaded bolts 34, and the lower end of each threaded bolt 34 is fixedly connected to the extrusion plate 35, and the end of the threaded bolt 34 away from the extrusion plate 35 is fixedly connected to the knob 36.

[0039] In this embodiment: since support plates 31 are provided on both sides of the vertical plate 21, the staff can rotate the knob 36, and the knob 36 rotates to cause the threaded bolt 34 to push the extrusion plate 35 to move, and the fan is further fixed by the cooperation of the extrusion plate 35 and the buffer plate 32. This design can further prevent the fan from deviating during the processing process.

[0040] Going further:

[0041] In an optional embodiment, a connecting hook 1 37 is fixedly connected to the bottom surface of the buffer plate 32, and a connecting hook 2 39 is fixedly connected to the surface of the bottom plate 1. The connecting hook 1 37 and the connecting hook 2 39 correspond one to one. A spring damper 38 is arranged between the connecting hook 1 37 and the connecting hook 2 39, and connecting hooks 3 that are compatible with the connecting hook 1 37 and the connecting hook 2 39 are respectively provided at both ends of the spring damper 38.

[0042] In this embodiment, a spring damper 38 is provided between the buffer plate 32 and the base plate 1 through the cooperation of the connecting hook 1 37 , the connecting hook 2 39 and the connecting hook 3 . During the bending process, the spring damper 38 prevents the fan from breaking due to excessive pressure.

[0043] It should be noted that the spring damper 38 is composed of a cylinder, a piston, oil, a piston rod and a spring. When the spring is compressed, the piston moves downward, the space under the piston becomes smaller, and the oil is squeezed and flows upward. Conversely, the oil flows downward. During the flow of the oil, it passes through the valve hole on the piston. The oil encounters resistance when passing through the valve hole, causing the piston movement to slow down, and part of the impact force is absorbed and slowed down by the oil.

[0044] Working principle: Because the surface of the bottom plate 1 is provided with a bearing plate 22 through the vertical plate 21, and the surface of the bearing plate 22 is provided with a bending trough 28, the staff can place the part of the fan that needs to be bent above the bending trough 28, and start the cylinder 25. The cylinder 25 pushes the fixed plate 26 and the bending block 27 to move, and the fan is bent through the cooperation of the bending block 27 and the bending trough 28. With this design, the fan can be bent conveniently. Because a reinforcement plate 29 is provided, during the bending process of the fan, the bending trough 28 is reinforced by the provided reinforcement plate 29 to prevent deviation of the bent part The phenomenon of this problem can be solved by providing support plates 31 on both sides of the vertical plate 21. The staff can rotate the knob 36, and the knob 36 rotates to make the threaded bolt 34 push the extrusion plate 35 to move, and the fan is further fixed by the cooperation of the extrusion plate 35 and the buffer plate 32. This design can further prevent the fan from deviating during the processing process. A spring damper 38 is provided between the buffer plate 32 and the bottom plate 1 through the cooperation of the connecting hook 1 37, the connecting hook 2 39 and the connecting hook 3. During the bending process, the cooperation of the spring damper 38 and the spring 310 can prevent the fan from breaking due to excessive pressure.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
