[0001] This invention relates to the technical field of new energy equipment in emerging strategic industries, and in particular to a wind power generator blade forming device. Background Technology

[0002] In the field of wind energy extraction, generator blades are the main components for absorbing wind energy. They can drive the generator to operate and generate electricity by being propelled by wind energy, thus realizing the extraction of wind energy.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0027] like Figures 1 to 5As shown, a wind power generator blade forming device of the present invention includes a forming base plate 1. A movable ring 2 is sleeved on the outer side of one end of the forming base plate 1. A clamping structure is provided inside the movable ring 2. The clamping structure is used to fix the end of the forming base plate 1. A sliding cylinder 3 is provided on the outer wall of the movable ring 2. A guide groove plate 4 is provided on the outer side of the movable ring 2. A guide groove 5 is provided on the inner wall of the guide groove plate 4. The outer end of the sliding cylinder 3 is slidably inserted into the guide groove 5. A convex U-shaped wheel 6 is contacted at the top of the forming base plate 1, and a concave U-shaped wheel 7 is contacted at the bottom of the forming base plate 1.

[0028] Specifically, the molded substrate 1 is arc-shaped, and its width at the beginning is smaller than its width at the end. The moving ring 2 is located at the beginning of the molded substrate 1. The overall shape of the guide groove plate 4 is arc-shaped, and the cross-sectional shape of the guide groove plate 4 is arc-shaped. The moving ring 2 is located inside the guide groove plate 4. The guide groove 5 is semi-spiral in shape and bends along the inner wall of the guide groove plate 4. The convex U-shaped wheel 6 and the concave U-shaped wheel 7 can extrude the molded substrate 1. Thus, after the molded substrate 1 is rolled by the convex U-shaped wheel 6 and the concave U-shaped wheel 7, the molded substrate 1 undergoes arc-shaped bending deformation.

[0029] In practical use, the first end of the molding substrate 1 is fixed to the clamping structure inside the moving ring 2. The convex U-shaped wheel 6 and the concave U-shaped wheel 7 squeeze the molding substrate 1, pushing the moving ring 2 to move in an arc along the overall arc direction of the guide groove plate 4. The moving ring 2 drives the sliding cylinder 3 to slide in the guide groove 5. The guide groove 5 guides the sliding cylinder 3, thereby causing the moving ring 2 to rotate during movement. The moving ring 2 drives the first end of the molding substrate 1 to move synchronously through the clamping structure. At the same time, due to the rotation of the moving ring 2, the moving ring 2 drives... The first end of the molding substrate 1 is twisted and deformed, and the molding substrate 1 in the guide groove plate 4 is twisted and deformed as a whole. At the same time, the moving molding substrate 1 drives the convex U-shaped wheel 6 and the concave U-shaped wheel 7 to rotate synchronously. The convex U-shaped wheel 6 and the concave U-shaped wheel 7 simultaneously squeeze and deform the molding substrate 1, so that the molding substrate 1 undergoes concave arc deformation. When the molding substrate 1 passes through the convex U-shaped wheel 6 and the concave U-shaped wheel 7, the deformation processing of the molding substrate 1 is completed. At this time, the molding substrate 1 is deformed from a flat plate to a twisted arc state.

[0030] By using a rolling deformation method to deform the molding substrate 1 into an arc shape, and then combining it with a twisting deformation method to make the molding substrate 1 into a twisted state, the shape of the molding substrate 1 is transformed from a flat plate to a twisted arc shape, thus realizing the extrusion molding process of the molding substrate 1. This method can effectively simplify the processing steps of the molding substrate 1, realize the rapid molding process of the molding substrate 1, reduce cost input, and improve work efficiency.

[0031] like Figure 5As shown, as a preferred embodiment of the above, the clamping structure includes two U-shaped plates 8 arranged opposite to each other. The U-shaped plates 8 move along the radial direction of the moving ring 2. Both ends of the U-shaped plates 8 are provided with a first push-pull plate 9 at an incline. A first leaf spring 10 is connected between the first push-pull plate 9 and the U-shaped plate 8. A flat pressure plate 11 is rotatably provided at the outer end of the first push-pull plate 9. A side pressure plate 12 is rotatably connected between the two flat pressure plates 11.

[0032] Specifically, when the U-shaped plate 8 is pushed to move along the radial direction of the moving ring 2 toward the side wall of the first end of the forming substrate 1, the side pressure plate 12 first contacts the side wall of the forming substrate 1. At this time, the side pressure plate 12 stops moving, the U-shaped plate 8 continues to move and pushes the flat pressure plate 11 to rotate toward the plane of the forming substrate 1. The two flat pressure plates 11 on the U-shaped plate 8 rotate synchronously and perform compression and fixing treatment on the upper and lower planes of the forming substrate 1. At this time, since the two U-shaped plates 8 move synchronously relative to each other, the two side pressure plates 12 on the two U-shaped plates 8 perform horizontal compression and fixing treatment on the forming substrate 1, and the two flat pressure plates 11 on the U-shaped plate 8 perform vertical compression and fixing treatment on the forming substrate 1, thereby realizing multi-directional fixing of the forming substrate 1 and improving the fixing strength of the forming substrate 1.

[0033] like Figure 6 As shown, in a preferred embodiment, the outer wall of the U-shaped plate 8 is provided with a guide plate 13. The outer end of the guide plate 13 passes through the movable ring 2 and is slidably connected. A push-pull ring 14 is slidably provided inside the movable ring 2. Two second push-pull plates 15 are obliquely rotatably provided on one side wall of the push-pull ring 14. The outer ends of the second push-pull plates 15 are rotatably mounted on the guide plate 13. The other end of the push-pull ring 14 is provided with a first cylinder 16. The fixed end of the first cylinder 16 is mounted on the inner wall of the movable ring 2.

[0034] Specifically, the first cylinder 16 can push the push-pull ring 14 to move within the moving ring 2. The push-pull ring 14 can push the guide plate 13 to move through the second push-pull plate 15. The guide plate 13 can drive the U-shaped plate 8 to move, thereby adjusting the position of the U-shaped plate 8. The guide plate 13 simultaneously guides the U-shaped plate 8.

[0035] like Figures 1 to 5 As shown, as a preferred embodiment of the above, it also includes a base plate 17, a guide groove plate 4 fixed on the base plate 17, a rotating column 18 rotatably provided on the top of the base plate 17, teeth provided on the outer wall of the rotating column 18, a gear 19 meshing on the teeth of the rotating column 18, a first motor 20 provided at the bottom of the base plate 17, the first motor 20 being connected to the gear 19 in a transmission, a connecting arm 21 fixed on the outer wall of the rotating column 18, a support ring 22 fixed at the outer end of the connecting arm 21, and the support ring 22 being rotatably sleeved on the outer wall of the moving ring 2.

[0036] Specifically, the first motor 20 can drive the rotating column 18 to rotate through the gear 19. The rotating column 18 can drive the moving ring 2 to move through the connecting arm 21 and the support ring 22, so that the moving ring 2 can move in an arc inside the guide groove plate 4. At the same time, due to the rotation of the moving ring 2, the moving ring 2 can rotate on the support ring 22.

[0037] like Figure 3 As shown, as a preferred embodiment of the above embodiment, a rotating sleeve 23 is rotatably sleeved on the outer wall of the rotating column 18. The rotating sleeve 23 passes through the connecting arm 21 and slides relative to it. An extension plate 24 is provided on the outer wall of the rotating sleeve 23. A lifting structure is provided on the extension plate 24. The lifting structure is used to lift and transport the tail end of the molding substrate 1.

[0038] A second leaf spring 25 is fixed on the outer wall of the extension plate 24. The outer end of the second leaf spring 25 is provided with an arc-shaped frame 26. The arc-shaped frame 26 is fixed on the outer wall of the rotating column 18. A limiting plate 27 is provided on the side wall of the connecting arm 21. The outer end of the limiting plate 27 contacts the outer wall of the extension plate 24.

[0039] Specifically, the second leaf spring 25 pushes the extension plate 24 to be pressed against the limiting plate 27, and the limiting plate 27 limits the extension plate 24. The lifting structure can lift the tail end of the molding substrate 1. When the rotating column 18 rotates, the rotating column 18 can drive the extension plate 24 to rotate synchronously, thereby realizing the synchronous conveying of the tail end of the molding substrate 1 and preventing the tail end of the molding substrate 1 from bending and shaking arbitrarily. When the extension plate 24 moves to the specified position, the extension plate 24 is pushed to stop moving. At this time, the molding substrate 1 and the extension plate 24 gradually separate, and the rotating column 18 and the rotating sleeve 23 generate relative movement, and the second leaf spring 25 undergoes elastic deformation.

[0040] like Figure 2 and Figure 4 As shown, as a preferred embodiment of the above, the lifting structure includes a wedge 28 slidably mounted on the extension plate 24, a third leaf spring 29 connecting the wedge 28 and the extension plate 24, an extrusion plate 30 being provided in contact with both the upper and lower planes of the molding substrate 1, two rotating plates 31 being rotatably mounted on the outer wall of the extrusion plate 30, the two rotating plates 31 being parallel, the outer ends of the rotating plates 31 being rotatably mounted on the extension plate 24, two push-pull rods 32 being rotatably mounted on the wedge 28, the outer ends of the push-pull rods 32 being rotatably connected to one of the rotating plates 31 on the extrusion plate 30;

[0041] An outer frame 34 is fitted around the outer sides of the convex U-shaped wheel 6 and the concave U-shaped wheel 7, and a push plate 33 is provided on the outer wall of the outer frame 34.

[0042] Specifically, the third leaf spring 29 generates an elastic thrust on the wedge block 28. The wedge block 28 can push the two extrusion plates 30 closer together through the two push-pull rods 32 and the two rotating plates 31 on each extrusion plate 30 to extrude and fix the tail end of the forming substrate 1 between them. When the rotating column 18 rotates, the extension plate 24 can lift and transport the tail end of the forming substrate 1 through the two extrusion plates 30. When the inclined surface of the wedge block 28 contacts the push plate 33, the push plate 33 can push the wedge block 28 to move toward the rotating column 18. At this time, the wedge block 28 can pull the two extrusion plates 30 to separate from each other, thereby stopping the fixing work on the tail end of the forming substrate 1. The tail end of the forming substrate 1 can pass smoothly through the convex U-shaped wheel 6 and the concave U-shaped wheel 7.

[0043] like Figure 2 As shown, in a preferred embodiment, the bottom of the outer frame 34 is provided with two second motors 35. The output end of the second motor 35 is provided with a double-threaded rod 36, which extends vertically into the outer frame 34, and the threads on the upper and lower sides of the double-threaded rod 36 have opposite directions. Two threaded sleeves 37 are screwed onto the double-threaded rod 36, and the threaded sleeves 37 are vertically slidably mounted on the inner side wall of the outer frame 34. A connecting shaft 38 is rotatably provided on the threaded sleeve 37. One of the two connecting shafts 38 on the double-threaded rod 36 is connected to the end of the outwardly convex U-shaped wheel 6, and the other connecting shaft 38 is connected to the end of the inwardly concave U-shaped wheel 7.

[0044] Specifically, the second motor 35 can push two threaded sleeves 37 to move synchronously in opposite directions through the double-screw rod 36. The threaded sleeves 37 can drive the outer convex U-shaped wheel 6 and the inner concave U-shaped wheel 7 to move synchronously in opposite directions through the two connecting shafts 38, so that the molding substrate 1 can pass through the outer convex U-shaped wheel 6 and the inner concave U-shaped wheel 7, which is convenient for feeding. At the same time, the distance between the outer convex U-shaped wheel 6 and the inner concave U-shaped wheel 7 can be easily adjusted.

[0045] like Figure 2 As shown, in a preferred embodiment, both connecting shafts 38 on the convex U-shaped wheel 6 are slidably fitted with conveying rings 39. The diameter of the conveying rings 39 is equal to the maximum diameter of the convex U-shaped wheel 6. A fixing ring 40 is rotatably mounted on the conveying rings 39. A sliding plate 41 is fixed to the top of the fixing ring 40. A groove is opened on the top of the outer frame 34. Two sliders 42 are slidably mounted in the groove. The top of the sliding plate 41 slides through the sliders 42. A second cylinder 43 is provided on the top of the outer frame 34. Two third push-pull plates 44 are rotatably mounted on the movable end of the second cylinder 43. The inclination directions of the two third push-pull plates 44 are opposite. The outer ends of the third push-pull plates 44 are rotatably mounted on the sliders 42.

[0046] Specifically, since the diameter of the conveying ring 39 is equal to the maximum diameter of the convex U-shaped wheel 6, after the first end of the forming substrate 1 passes through the convex U-shaped wheel 6 and the concave U-shaped wheel 7, the conveying ring 39 simultaneously contacts the top of the forming substrate 1. At this time, the conveying ring 39 and the concave U-shaped wheel 7 provide stable conveying of the forming substrate 1. When it is necessary to extrude and deform the forming substrate 1, the second cylinder 43 pushes the two sliders 42 to separate from each other through the two third push-pull plates 44. The sliders 42 drive the two conveying rings 39 to separate from each other through the slide plate 41 and the fixing ring 40. The conveying rings 39 separate from the forming substrate 1, and the convex U-shaped wheel 6 is adjusted by the second motor 35. The position between the convex U-shaped wheel 6 and the concave U-shaped wheel 7 allows the convex U-shaped wheel 6 and the concave U-shaped wheel 7 to gradually approach each other and extrude and deform the forming substrate 1. By setting the conveying ring 39, the conveying and extrusion deformation of the forming substrate 1 can be directly switched. This avoids the situation where the convex U-shaped wheel 6 cannot effectively convey the forming substrate 1 when it needs to be conveyed. At the same time, when the convex U-shaped wheel 6 and the concave U-shaped wheel 7 approach each other, a deformation effect with a gradually increasing arc of extrusion deformation of the forming substrate 1 can be formed, thereby improving the smoothness of the deformation work of the forming substrate 1 and avoiding stress accumulation inside the forming substrate 1.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
