Description

Technical Field

[0001] This utility model relates to the field of axial flow fan blade manufacturing technology, specifically to a shaping mechanism for axial flow fan blades. Background Technology

[0002] Axial flow fan blades are generally molded in one piece using injection molding. A qualified axial flow fan blade is required to have blades on the same plane. However, since the existing molding process for axial flow fan blades generally involves natural cooling, it is difficult to ensure that the blades do not deform during the slow natural cooling process.

[0003] Chinese Patent No. CN218838431U discloses a shaping mechanism for axial flow fan blades, including a mounting plate and a shaping device. The shaping device is detachably mounted on the mounting plate, and multiple sets of shaping devices are arranged around the edge of the mounting plate. The shaping device includes a first shaping component, an adsorption component, and a second shaping component arranged sequentially. The adsorption component includes a suction cup for adsorbing the middle part of the axial flow fan blade. The top of the first shaping component is connected to the mounting plate, and the bottom of the first shaping component abuts against one end of the edge of the axial flow fan blade. The top of the second shaping component is connected to the mounting plate, and the bottom of the second shaping component abuts against the other end of the edge of the axial flow fan blade. The shaping mechanism for axial flow fan blades proposed in this technical solution helps to solve the technical problems of poor shaping effect and low production efficiency of existing axial flow fan blade shaping devices.

[0004] However, in the above technical solution, only the first and second shaping components are used to restrict the two ends of the axial flow fan blades, and the suction cups are used to fix the axial flow fan blades. However, when using this device, the suction cups need to be attached to the axial flow fan blades one by one. If a single suction cup is misaligned, the other suction cups will also need to be adjusted. Utility Model Content

The two parallel fixing rods 11 are connected to the second mounting plate 9. The two moving rods 7 are one short and one long. When the shaping component is in use, the moving component 3 moves with the moving plate 2 and approaches the fixing component 4. The two moving rods 7 on the moving component 3 and the two fixing rods 11 on the fixing component 4 work together to clamp and restrict the position of the axial flow fan blades at multiple points.

[0023] Example 2

[0024] like Figures 2-4 As shown, the present invention proposes a shaping mechanism for an axial flow fan blade. Compared with Embodiment 1, this embodiment describes the detailed structure of the shaping component. The moving rod 7 and the fixed rod 11 have the same structure. The moving rod 7 is composed of a bolt part 13 and a rod body part 14. The bolt part 13 is threadedly connected to the first mounting plate 5, and the rod body part 14 is connected to the other end of the bolt part 13.

[0025] In an optional embodiment, the receiving groove 8 and the limiting groove 12 have the same structure. Both the receiving groove 8 and the limiting groove 12 are connected with a plurality of symmetrically arranged limiting protrusions 15. The limiting protrusions 15 in the receiving groove 8 and the limiting groove 12 are slidably connected to the notches opened on the first mounting plate 5 and the second mounting plate 9, respectively. The limiting protrusions 15 act like slide rails and sliders to prevent the object from shaking or tilting when it moves.

[0026] In an optional embodiment, both the fixed rod 11 and the movable rod 7 are connected to a buffer pad 16 near the end of the axial flow fan blade; the buffer pad 16 adopts a spherical structure to accommodate blades of various shapes, and the buffer pad 16 is made of, but is not limited to, rubber and silicone materials.

[0027] In an optional embodiment, a plurality of guide rods 17 are connected to the mounting base 1, and a support ring 18 is connected to each guide rod 17. The movable disk 2 is slidably connected to the guide rods 17, and the movable disk 2 is detachably connected to the support ring 18.

[0028] In an optional embodiment, each support ring 18 is connected to a first magnetic element 19, and the movable disk 2 is connected to a second magnetic element 20 corresponding to the first magnetic element 19. The first magnetic element 19 and the second magnetic element 20 are magnetically connected.

[0030] In an optional embodiment, the movable disk 2 is provided with an indicator mark 22 and the mounting base 1 is provided with a reference mark 23; the indicator mark 22 and the reference mark 23 are used as a reference when placing the movable disk 2 to prevent axial flow fan blades from being damaged due to tilting.

[0031] In summary, when using this utility model, after the axial flow fan blade is injection molded, the operator takes out the axial flow fan blade and inserts its bushing into the positioning ring 21. Then, the axial flow fan blade is slightly rotated so that the lower and higher positions of the inclined blade contact the lower and higher fixing rods 11. Then, the moving plate 2 is inverted so that its moving part 3 is close to the mounting base 1. The indicator mark 22 on it corresponds to the reference mark 23 on the mounting base 1. Then, the through hole on it is aligned with the guide rod 17 for sliding connection. At this time, the support ring 18 and the first magnetic suction member 19 will block it. After the operator turns on the power, the first magnetic suction member 19 is energized and attracts the second magnetic suction member 20 to keep the position of the moving plate 2 fixed. At this time, the two moving rods 7 of one long and one short in the moving part 3 on the moving plate 2 correspond to the positions of the two fixing rods 11 of one short and one long on the fixing member 4. The axial flow fan blade is fixed and clamped by the buffer pad 16 connected to one end.
