Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade technology, and in particular to a wind turbine blade bonding angle mold and an integrated molding tool for the windward side and bonding angle. Background Technology

[0002] When manufacturing wind turbine blades, the bonding angle mold needs to be installed on the windward side mold of the wind turbine blade so that the bonding angle of the wind turbine blade is integrally formed with the windward side shell. The casting quality of the bonding angle directly affects the service life of the wind turbine blade.

[0003] In existing technologies, due to the long bonding angle of wind turbine blades, multiple bonding angle molds need to be spliced ​​together and then bonded to the flange surface of the blade mold. However, when the bonding angle of the wind turbine blade is integrally formed with the windward shell and adhesive is used, a large amount of adhesive adheres to the bonding angle mold, which is difficult to clean. If the adhesive falls off, it will also cause the bonding angle to misalign, resulting in wrinkles in the bonding angle fabric layer and impurities in the bonding angle fabric layer, which may lead to problems such as failing to meet the design strength of the wind turbine blade. Alternatively, an additional positioning device can be set to fix the spliced ​​bonding angle mold to the flange surface of the blade mold, but the components of the positioning device are prone to falling off, which also affects the design strength of the wind turbine blade.

[0004] Therefore, there is an urgent need for a mold for bonding the wind turbine blades and a tooling for integrally molding the windward side and the bonding corner, in order to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mold for bonding angle of wind turbine blades and a tooling for integrally forming the windward side and bonding angle, which can ensure the design strength of wind turbine blades.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, a wind turbine blade bonding angle mold is provided, which is installed on the flange face of a blade mold, the blade mold further having a housing face, the wind turbine blade bonding angle mold comprising:

[0008] The mold body has a mounting surface that is parallel to and directly opposite the flange surface;

[0009] An adhesive corner forming part has an adhesive corner working surface and is connected to the mold body at an angle.

[0010] One of the mounting surface and the flange surface is provided with a snap-fit ​​groove, and the other is provided with a snap-fit ​​part that can snap into the snap-fit ​​groove. When the wind turbine blade bonding angle mold is installed on the blade mold, the snap-fit ​​groove and the snap-fit ​​part snap into each other, and the bonding angle working surface is connected to the shell surface.

[0011] In some embodiments, the snap-fit ​​portion is a boss.

[0012] In some embodiments, the peripheral sidewall of the snap-fit ​​portion gradually slopes from top to bottom away from its center to form a frustum.

[0013] In some embodiments, the snap-fit ​​slot is a through slot.

[0014] In some embodiments, a plurality of the snap-fit ​​portions are spaced apart along the axial direction of the wind turbine blade bonding angle mold, and the number of snap-fit ​​slots is the same as the number of snap-fit ​​portions and they are snapped together one by one.

[0015] In some embodiments, the mounting surface is fully covered with a Teflon plate.

[0016] In some embodiments, when the snap-fit ​​groove and the snap-fit ​​part snap together, the surface of the Teflon plate and the flange surface are spaced apart.

[0017] Secondly, a tooling for integrally forming the windward side and bonding angle of a wind turbine blade is provided, including a blade mold and the aforementioned wind turbine blade bonding angle mold, wherein the wind turbine blade bonding angle mold is installed on the flange surface of the blade mold.

[0018] The beneficial effects of this utility model are:

[0019] The wind turbine blade bonding angle mold provided in this embodiment has a snap-fit ​​groove on one of the mounting surface of the wind turbine blade bonding angle mold and a snap-fit ​​part on the other, which can snap into the snap-fit ​​groove. When the wind turbine blade bonding angle mold is installed on the blade mold, the snap-fit ​​groove and the snap-fit ​​part snap into each other, thereby restricting the spatial position of the wind turbine blade bonding angle mold relative to the blade mold along its own chord direction. Moreover, the snap-fit ​​part snaps into the snap-fit ​​groove, avoiding contact between the snap-fit ​​part and the snap-fit ​​groove and the resin structural adhesive, solving the problem of the snap-fit ​​part and the snap-fit ​​groove being contaminated by resin and structural adhesive, and at the same time preventing the positioning structure from falling off and being damaged during use.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 2 As shown, this utility model provides a mold for bonding angle of wind turbine blades and a tooling for integrally forming the windward side and bonding angle.

[0031] Figure 1 A schematic diagram of the structure of the tooling for integrally molding the windward surface and the bonding corner provided by this utility model is shown. Figure 2 A cross-sectional schematic diagram of the tooling for integrally molding the windward side and the bonding corner is shown. (See diagram below.) Figures 1 to 2As shown, the wind turbine blade bonding angle mold provided in this embodiment is installed on the flange face 101 of the blade mold 100. The blade mold 100 also has a shell face 102. The wind turbine blade bonding angle mold includes a mold body 1 and a bonding angle forming part 2. The mold body 1 has a mounting surface 11 that is parallel to and directly opposite the flange face 101. The bonding angle forming part 2 has a bonding angle working surface 21 and is connected to the mold body 1 at an angle. One of the mounting surface 11 and the flange face 101 is provided with a snap-fit ​​groove 103, and the other is provided with a snap-fit ​​part 12 that can snap into the snap-fit ​​groove 103. When the wind turbine blade bonding angle mold is installed on the blade mold 100, the snap-fit ​​groove 103 and the snap-fit ​​part 12 snap into each other, and the bonding angle working surface 21 is connected to the shell face 102. It should be noted that when using the tooling for integral molding of the wind turbine blade's windward side and bonding angle to integrally mold the wind turbine blade's windward side and bonding angle, the bonding angle working surface 21 of the wind turbine blade bonding angle mold is used to mold the bonding angle, and the shell surface 102 of the blade mold 100 is used to mold the windward side of the blade.

[0032] The wind turbine blade bonding angle mold provided in this embodiment has a snap-fit ​​groove 103 on one of the mounting surface 11 of the wind turbine blade bonding angle mold and the flange surface 101 of the blade mold 100, and a snap-fit ​​part 12 that can snap into the snap-fit ​​groove 103 on the other. When the wind turbine blade bonding angle mold is installed on the blade mold 100, the snap-fit ​​groove 103 and the snap-fit ​​part 12 snap into each other, thereby restricting the spatial position of the wind turbine blade bonding angle mold relative to the blade mold 100 along its own chord direction. The snap-fit ​​part 12 snaps into the snap-fit ​​groove 103, avoiding contact between the snap-fit ​​part 12 and the snap-fit ​​groove 103 and the resin structural adhesive, solving the problem of the snap-fit ​​part 12 and the snap-fit ​​groove 103 being contaminated by resin and structural adhesive. At the same time, it avoids the positioning structure from easily falling off and being damaged during use, which would lead to the problem of limiting failure.

[0033] Continue as Figures 1 to 2 As shown, the snap-fit ​​part 12 is a boss, which allows for quick release of the snap-fit ​​relationship between the snap-fit ​​part 12 and the snap-fit ​​groove 103 after the wind turbine blade's windward side and bonding corner are integrally formed. This allows the wind turbine blade bonding corner mold to be removed from the blade mold 100, and the structural adhesive that may remain on the flange surface 101 of the blade mold 100 to be cleaned. It should be noted that during the integral forming of the wind turbine blade's windward side and bonding corner, some structural adhesive will flow from the connection point between the shell surface 102 and the bonding corner working surface 21 to the gap between the flange surface 101 of the blade mold 100 and the mounting surface 11 of the wind turbine blade bonding corner mold. This portion of structural adhesive will not affect the integral forming of the wind turbine blade's windward side and bonding corner, but it needs to be cleaned so that the tooling for integral forming of the wind turbine blade's windward side and bonding corner can be reused repeatedly.

[0034] Preferably, the peripheral sidewall of the snap-fit ​​part 12 gradually slopes away from its center from top to bottom to form a frustum, thereby making it easier for workers to remove the wind turbine blade bonding angle mold from the blade mold 100. It should be noted that the snap-fit ​​part 12 can be a circular boss, a 3-frustum, a 4-frustum, a 6-frustum, etc. Those skilled in the art can reasonably set it according to actual needs, and it will not be described in detail here.

[0035] When the windward side of a wind turbine blade is integrally molded with the bonding corner, operator error may cause some structural adhesive to flow from the junction of the shell surface 102 and the bonding corner working surface 21 to the gap between the flange surface 101 of the blade mold 100 and the mounting surface 11 of the wind turbine blade bonding corner mold, and then flow into the snap-fit ​​groove 103, thereby contaminating the snap-fit ​​part 12 and the snap-fit ​​groove 103. To solve the above technical problem, in some embodiments, the snap-fit ​​groove 103 is a through groove, so that some structural adhesive that flows into the snap-fit ​​groove 103 due to accidental circumstances can flow out from the through groove, preventing structural adhesive from remaining in the snap-fit ​​groove 103 and contaminating the snap-fit ​​part 12 and the snap-fit ​​groove 103.

[0036] Continue as Figures 1 to 2 As shown, several snap-fit ​​parts 12 are spaced apart along the axial direction of the wind turbine blade bonding angle mold. The number of snap-fit ​​grooves 103 is the same as the number of snap-fit ​​parts 12 and they are snapped in one-to-one. This allows for multi-point positioning of the wind turbine blade bonding angle mold relative to the blade mold 100, and better restricts the spatial position of the wind turbine blade bonding angle mold relative to the blade mold 100 along its own chord direction.

[0037] In some embodiments, a plurality of snap-fit ​​parts 12 are arranged at intervals along the chord direction of the wind turbine blade bonding angle mold, and the number of snap-fit ​​grooves 103 is the same as the number of snap-fit ​​parts 12 and they are snapped in one-to-one, thereby positioning the spatial position of the wind turbine blade bonding angle mold relative to the blade mold 100 at multiple points, and better limiting the spatial position of the wind turbine blade bonding angle mold relative to the blade mold 100 along its own chord direction.

[0038] In other embodiments, the mounting surface 11 of the wind turbine blade bonding angle mold is fully covered with a Teflon plate, thereby reducing the adhesion of the structural adhesive to the mounting surface 11 and preventing the structural adhesive from flowing from the connection position between the shell surface 102 and the bonding angle working surface 21 to the gap between the flange surface 101 of the blade mold 100 and the mounting surface 11 of the wind turbine blade bonding angle mold. This would cause the blade mold 100 to stick to the wind turbine blade bonding angle mold, making it difficult for workers to remove the wind turbine blade bonding angle mold from the blade mold 100 after the windward side of the wind turbine blade and the bonding angle are integrally formed.

[0039] Continue as Figures 1 to 2As shown, when the snap-fit ​​groove 103 and the snap-fit ​​part 12 snap together, the Teflon plate surface and the flange surface 101 are spaced apart, thereby increasing the width of the flow channel in the gap between the flange surface 101 of the blade mold 100 and the mounting surface 11 of the wind turbine blade bonding angle mold from the connection position between the shell surface 102 and the bonding angle working surface 21 to the connection position between the shell surface 102 and the bonding angle working surface 21, and shortening the flow length of the structural adhesive, thereby preventing the structural adhesive from flowing into the snap-fit ​​groove 103.

[0040] The wind turbine blade windward side and bonding corner integral molding tooling provided in this embodiment includes a blade mold 100 and the aforementioned wind turbine blade bonding corner mold. The wind turbine blade bonding corner mold is installed on the flange face 101 of the blade mold 100, thereby avoiding contact between the snap-fit ​​part 12 and the snap-fit ​​groove 103 and the resin structural adhesive, solving the problem of the snap-fit ​​part 12 and the snap-fit ​​groove 103 being contaminated by resin and structural adhesive, and at the same time avoiding the positioning structure from falling off and being damaged during use, resulting in the problem of limit failure, thereby ensuring the design strength of the wind turbine blade.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
