Description

Technical Field

[0001] This application relates to the field of wind power technology, and in particular to a molding die for a blade web. Background Technology

[0002] With the continuous development of new energy technologies, the proportion of wind power generation is also constantly increasing. Wind power generation utilizes the widely flowing wind in nature to generate electricity. The wind drives the blades of the wind turbine to rotate, thereby converting wind energy into electrical energy. Since no pollutants are produced during the power generation process, it is relatively environmentally friendly and is an important source of electricity among new energy sources.

[0003] The web is a crucial part of the blade, playing a vital role in structural reinforcement. It is typically manufactured using molds, and the molding area in the blade web molding mold is designed according to the shape of the web. Therefore, improving the applicability of the mold to manufacture different types of webs is an important issue. Utility Model Content

[0004] The purpose of this application is to provide a molding die for a blade web, which can improve the applicability of the die so as to produce different webs.

[0005] To address the aforementioned technical problems, this application provides a forming mold for a blade web. The forming mold includes a base, a mold boss, and a side-stop assembly. The base has a support platform, and the support platform has a forming area. The mold boss includes multiple modules spliced ​​together within the forming area. The modules abut against each other and form a processing surface on the side away from the support platform. The processing surface is used to lay the forming material for the web. Each module is detachably connected to the support platform. The side-stop assembly includes a first limiting member and a second limiting member spaced apart on the support platform. The first limiting member is located on one side of the mold boss, and the second limiting member is located on the other side of the mold boss.

[0006] The blade web forming mold provided in this application uses multiple modules assembled on a support platform to form a mold boss. The modules are detachably connected to the support platform, allowing them to be connected to form the mold boss or detached from it. By assembling multiple modules, processing surfaces of different sizes can be formed to accommodate the forming of different webs, thereby improving the applicability of the forming mold. Furthermore, when adjusting the size of the mold boss, the modules can be reused, thus reducing the cost of the forming mold.

[0007] In some embodiments, the forming mold for the blade web also includes fasteners. A mounting component is provided on the support platform, and a hollow area for accommodating the mounting component is provided on the side of the module near the support platform. The fasteners pass through the module and connect to the mounting component. In this way, the module can be fixed to the support platform using fasteners, ensuring the stability of the connection between the module and the support platform.

[0008] In some embodiments, the side of the module away from the support platform has a groove communicating with the hollowed-out area, and a pressing member located within the groove, through which fasteners pass to connect with the mounting component. This allows for a larger area of ​​compression by placing the pressing member within the module's groove, ensuring the stability of the module when fixed to the support platform.

[0009] In some embodiments, the support platform is provided with a connector, and the module has a groove on the side near the support platform to receive the connector, allowing the connector to fit the module against the support platform. This simplifies the connection between the module and the support platform by creating an engagement between the connector and the groove.

[0010] In some embodiments, the connector includes a first side and a second side spaced apart, and the slide includes a first sidewall abutting the first side and a second sidewall abutting the second side. The distance between the first and second side and the distance between the first and second sidewalls gradually increases in the direction away from the support platform. This ensures the connector's limiting effect on the module by making the cross-section of the connector and the slide a matching trapezoidal shape.

[0011] In some implementations, the two ends of the slide pass through the module. This facilitates a better fit between the slide and the connector by having both ends of the slide pass through the module.

[0012] In some implementations, at least some modules have the same projected area on the support platform. This allows for mass production of modules by using standardized specifications for different modules.

[0013] In some implementations, a cavity is provided within the module. This allows for the module to be lightweight.

[0014] In some implementations, the module is made of thermally conductive plastic. This allows for module weight reduction and facilitates heat conduction during web curing.

[0015] In some embodiments, the forming mold for the blade web further includes a first positioning member and a second positioning member. The first positioning member abuts against one side of the mold boss, and the second positioning member abuts against the other side of the mold boss. This allows for easier demolding after the web is formed by placing the positioning member near the limiting member. Attached Figure Description

The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0027] Wind energy boasts advantages such as environmental friendliness and abundant reserves. Wind energy can be converted into electricity through wind turbines. The blade is a crucial component of a wind turbine. In a wind turbine, the blade is the part that rotates with the wind, and the web is located inside the blade. Blades are typically hollow composite materials composed of a leeward and a windward side. The hollow portion of the blade is supported along its length by the web. The web is fixed inside the blade via adhesive flanges, connecting to both the top and bottom of the blade to enhance its overall strength and rigidity, extending its service life. The web is usually designed in a C-shape or I-shape. The main body of the web is a long, strip-like structure, with its width gradually decreasing from the root to the tip, supporting the blade between the top and bottom. In other words, the main width of the web corresponds to the internal spatial shape of the blade from root to tip. The flanged portion of the web forms the flange structure that fixes it to the blade.

[0028] During the fabrication of the web, a protruding platform is formed on the mold to lay the web molding material. Baffles are installed on both sides of the protruding platform for positioning. The space formed between the top surface of the protruding platform and the inner surface of the baffles is used for web molding. After the mold is formed, fiberglass cloth and core material are laid on the top surface of the protruding platform, vacuum-cast, and then demolded after heat curing to obtain the molded web. The angle between the baffles and the protruding platform is set according to the shape of the web; for ease of demolding, it is usually set to an obtuse angle. One baffle is used to form the windward flange of the web, and the other baffle is used to form the leeward flange. Rubber strip molds can also be set on both sides of the protruding platform, located inside the baffles. Since demolding is required at acute angles during web fabrication, setting rubber strip molds at these angles facilitates demolding and improves efficiency.

[0029] Currently, when forming a protruding platform, steel plates are cut according to the platform's shape to create a top plate, flanged plates, and upright plates. The top plate, upright plates, and flanged plates are then welded together as a single unit, requiring smooth welds with strict sealing requirements. No localized deformation is permitted after welding. Because the top plate, upright plates, and flanged plates require full welding, the large amount of welding and high technical demands increase manufacturing costs. Furthermore, once assembled, the shape of the protruding platform cannot be altered, making it unusable and resulting in waste.

[0030] Because the shape and size of the web plate can change, molding spaces of different sizes need to be designed. Currently, the protruding platform needs to be completely replaced when making different web plates to adapt to the web plate size. This results in low mold applicability, and the original protruding platform is wasted when molding different web plates, which is not conducive to reducing mold costs.

[0031] To improve mold adaptability and reduce mold costs, some embodiments of this application provide a forming mold for a blade web. In the blade web forming mold, a large number of modules are spliced ​​together to form a mold platform, which can be used to form webs of different sizes. Modules can be spliced ​​according to the size of the web to form mold bosses that match the size of the web. When manufacturing webs of different sizes, only the number of modules needs to be adjusted. Modules near the baffle can be ground or cut to fit the shape of the web flange. Uncut modules away from the baffle can be reused after the size of the manufactured web changes. This allows the mold to adapt to the forming of different webs, reduces waste of mold bosses, and lowers mold costs.

[0032] The following is combined Figures 1 to 7 This application describes the structure of the forming mold for the blade web provided in some embodiments.

[0033] like Figures 1 to 7 As shown, the forming mold for the blade web provided in some embodiments of this application includes a base 11, a mold boss 13, and a side-stop assembly. The base 11 is provided with a support platform 12, and the support platform 12 is provided with a forming area. The mold boss 13 includes multiple modules 130 spliced ​​and arranged in the forming area. The multiple modules 130 abut against each other and form a processing surface on the side away from the support platform 12. The processing surface is used to lay the forming material of the web 21. Each module 130 is detachably connected to the support platform 12. The side-stop assembly includes a first limiting member 14 and a second limiting member 15 spaced apart on the support platform 12. The first limiting member 14 is located on one side of the mold boss 13, and the second limiting member 15 is located on the other side of the mold boss 13.

[0034] The base 11 is the supporting part of the molding die. The base 11 provides a mounting base for other components. The support platform 12 is mounted on the base 11, providing a planar foundation for the mold boss 13. Simultaneously, the support platform 12 can also house a heating unit 102 to heat the web 21 during molding. The support height of the support platform 12 can be adjusted to ensure the parallelism of the support surface of the support platform 12 relative to the ground during the molding of the web 21. Figure 1 As shown, a plurality of adjustable connecting components 101 are provided between the support platform 12 and the base 11. By adjusting the connecting components 101, the height of the support platform 12 relative to the base 11 can be changed.

[0035] The mold boss 13 provides a platform for material laying during the molding of the web 21. The mold boss 13 is formed by splicing together independent modules 130. The modules 130 abut together to form a machining surface on the support platform 12 corresponding to the size of the web 21. The molding material of the web 21 can be laid on the machining surface for the molding of the web 21. The detachable connection between the module 130 and the support platform 12 can be achieved by fasteners 122 or by a snap-fit ​​mechanism. The projection shape of the module 130 on the support platform 12 can be polygonal, such as a triangle, rectangle, or square, or it can be trapezoidal.

[0036] The flange assembly is used to define the area of ​​the molding material of the web 21 and to form the flange of the web 21 at the edge of the mold boss 13. The first limiting member 14 and the second limiting member 15 are located on opposite sides of the mold boss 13, corresponding to the windward flange and the leeward flange of the web 21, respectively. Different limiting members are set for different side edges of the molding area. The first limiting member 14 and the second limiting member 15 can be fixed to the support platform 12 by welding to form the mold flange.

[0037] The blade web forming mold provided in some embodiments of this application uses multiple modules 130 spliced ​​together on a support platform 12 to form a mold boss 13. The modules 130 are detachably connected to the support platform 12, meaning they can be connected to the support platform 12 to form the mold boss 13, or they can be detached from the support platform 12. By splicing multiple modules 130, processing surfaces of different sizes can be formed to adapt to the forming of different webs 21, thereby improving the applicability of the forming mold. Furthermore, when adjusting the size of the mold boss 13, the modules 130 can be reused, thereby reducing the cost of the forming mold.

[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, module 130 can be connected to support platform 12 using fasteners 122 such as screws. The fasteners 122 can fix module 130 to support platform 12 through threaded connection, and can be easily assembled and disassembled.

[0039] The forming mold for the blade web may also include a fastener 122, an mounting component 121 is provided on the support platform 12, and a hollow area 131 for accommodating the mounting component 121 is provided on the side of the module 130 near the support platform 12. The fastener 122 passes through the module 130 and is connected to the mounting component 121.

[0040] Mounting member 121 has a threaded hole and protrudes from the support platform 12. Mounting member 121 can be a screw post or a cylindrical pin with internal threads, and can be fixed to the support platform 12 by welding. The relationship between mounting member 121 and module 130 can be one-to-one or many-to-one, meaning one module 130 can be connected to the support platform 12 by one or more fasteners 122. A cutout area 131 is provided on the side of module 130 closest to the support platform 12. The cutout areas 131 can be spaced apart or continuously distributed. When module 130 is placed on the support platform 12, mounting member 121 can enter the cutout area 131 to avoid interference between mounting member 121 and module 130.

[0041] After passing through module 130, fastener 122 engages with mounting component 121 to secure module 130 to support platform 12. To ensure the flatness of the machined surface, the head of fastener 122 is flush with the side of module 130 away from support platform 12, meaning the head of fastener 122 is located within the surface area of ​​module 130. This fastener connection ensures the stability of the connection between module 130 and support platform 12. Simultaneously, it facilitates disassembly of module 130 to adjust the shape and size of the machined surface of mold boss 13.

[0042] Additionally, the side of module 130 away from the support platform 12 may be provided with a groove 132 that communicates with the hollow area 131, and a pressing member 123 located in the groove 132, with the fastener 122 passing through the pressing member 123 and connected to the mounting member 121.

[0043] In other words, module 130 can be provided with a groove 132 to accommodate the pressing member 123. When connecting module 130 and support platform 12, the pressing member 123 can be placed in the groove 132 of module 130. The pressing member 123 can be plate-shaped. After the pressing member 123 and module 130 are engaged, fasteners 122 can be passed through the pressing member 123 and connected to the mounting member 121. Thus, the fastening effect of the fasteners 122 on the pressing member 123 effectively fixes module 130 to support platform 12. The pressing member 123 can form a large mating area with module 130, thereby ensuring the tightness of the connection between module 130 and support platform 12.

[0044] In some embodiments, the module 130 and the support platform 12 can also be connected by a snap-fit ​​mechanism.

[0045] like Figure 5 As shown, the support platform 12 may be provided with a connector 124, and the module 130 is provided with a groove 133 for accommodating the connector 124 on the side near the support platform 12. The connector 124 makes the module 130 fit against the support platform 12.

[0046] The connector 124 protrudes from the support platform 12 and can be configured as a block or a strip. The cross-sectional shape of the connector 124 is variable in size, meaning its cross-sectional dimensions vary. A groove 133 is provided on the side of the module 130 closest to the support platform 12, allowing the connector 124 to enter and fit tightly with it. The cross-sectional shape of the groove 133 is also variable in size. After the connector 124 engages with the groove 133, it limits the movement of the module 130 away from the support platform 12.

[0047] When module 130 needs to be disassembled, a force is applied along the extension direction of slide groove 133 to move the slider until connector 124 is completely disengaged from slide groove 133. By adopting the cooperation form between connector 124 and slide groove 133, the disassembly and assembly of module 130 can be facilitated, and the cooperation form between module 130 and support platform 12 can be simplified.

[0048] like Figure 5As shown, the connector 124 may include a first side 1241 and a second side 1242 spaced apart, and the slide 133 includes a first side wall 1331 abutting against the first side 1241 and a second side wall 1332 abutting against the second side 1242. The distance between the first side 1241 and the second side 1242, and the distance between the first side wall 1331 and the second side wall 1332, gradually increase in the direction away from the support platform 12.

[0049] The first side 1241 and the second side 1242 are the two sides of the connector 124 that are adjacent to the surface of the support platform 12. In the direction away from the support platform 12, the first side 1241 and the second side 1242 form a shape that is narrow at the bottom and wide at the top. That is, the cross-section of the connector 124 is an inverted trapezoidal shape. The cross-section of the groove 133 is also an inverted trapezoidal shape adapted to the connector 124, i.e., a dovetail groove. The groove 133 can be provided with an ever-expanding flared shape near the surface of the module 130 to reduce resistance when the connector 124 engages. After the connector 124 enters the groove 133, the connector 124 can prevent the slider from moving away from the support platform 12, thus limiting the slider's movement. In practice, the cross-section of the connector 124 can also be a regular shape such as a circle or an ellipse, or an irregular shape.

[0050] In some embodiments, the two ends of the slide 133 may extend through the module 130.

[0051] The groove 133 extends completely through both sides of the slider in its extension direction. When connecting the slider to the support platform 12, the connector 124 can enter the groove 133 from one side of the slider until the slider is fixed at a specific position on the support platform 12. By ensuring that both ends of the groove 133 extend through the slider, the connector 124 can enter from one end of the groove 133 or exit from one end. This facilitates the assembly and disassembly of the slider and simplifies the assembly and disassembly operations.

[0052] In practice, the slide 133 may also be provided through the module 130 at only one end. Alternatively, neither end of the slide 133 may be provided through the module 130. Instead, a clearance groove communicating with the slide 133 may be provided on the side of the slider near the support platform 12, so that the connector 124 can enter the clearance groove without obstruction and then enter the slide 133 through the clearance groove.

[0053] In some embodiments, at least some of the modules 130 may have the same projected area on the support platform 12.

[0054] In other words, different sliders can maintain the same shape and size. By using sliders of uniform specifications, the manufacturing cost of sliders can be reduced, which is conducive to molding a larger number of sliders for mass production of module 130, so as to splice them to form mold bosses 13 with different sized processing surfaces to adapt to the molding of web plates 21 of different sizes.

[0055] In addition, the slider near the edge of the mold boss 13 can be processed by grinding and cutting to adapt to the shape and size requirements of the web plate 21 near the flange.

[0056] In some embodiments, a cavity 134 may be provided within the module 130.

[0057] Cavity 134 is located inside module 130, and can be hollowed out in specific areas inside module 130. The inclusion of cavity 134 makes module 130 lighter. Simultaneously, the inclusion of cavity 134 reduces the amount of material used in manufacturing module 130, saving manufacturing costs. Module 130 can have multiple cavities 134, spaced apart from each other, to ensure the structural strength of module 130.

[0058] In practice, module 130 can be made of thermally conductive plastic.

[0059] The use of plastic material ensures the lightweight design of module 130. Furthermore, the thermal conductivity of the plastic allows for rapid heat transfer to the molding material of the web 21. This facilitates the curing process of the web 21 during molding, ensuring the molding quality of the web 21. The thermally conductive plastic can be PA6 (polycaprolactam) or PA66 (polyhexamethylene adipamide).

[0060] In addition, the molding die may also include a first positioning member 16 and a second positioning member 17. The first positioning member 16 abuts against one side of the mold boss 13 and is spaced apart from the first limiting member 14. The second positioning member 17 abuts against the other side of the mold boss 13 and is spaced apart from the second limiting member 15.

[0061] The first positioning element 16 and the second positioning element 17 can be rubber strips, forming a rubber strip mold at the edge of the mold boss 13. Since demolding is required at sharp angles during the fabrication of the web 21, setting the first positioning element 16 and the second positioning element 17 at these sharp angles facilitates demolding and improves efficiency. When producing the I-shaped web 21, a gap can be reserved between the positioning element and the mold boss 13. When producing the C-shaped web 21, the positioning element can be placed against the edge of the mold boss 13.

[0062] The blade web forming molds provided in some embodiments of this application can meet the production needs of different types of webs 21, such as I-shaped webs 21 and C-shaped webs 21. Furthermore, when the model of the produced web 21 changes, a new mold boss 13 shape can be formed simply by adjusting the number of modules 130, such as the number of thermally conductive engineering plastic film blocks. At the same time, most of the previously used engineering plastic modules 130 can be reused, improving the utilization rate of the modules 130 and reducing mold costs.

[0063] By increasing or decreasing the number and arrangement of the thermally conductive engineering plastic modules 130, the molding of webs 21 with different heights and widths can be adapted. During the molding process of the web 21, the thermally conductive engineering plastic modules 130 can transfer the heat required for the manufacturing of the web 21, thus meeting the heat requirements during the molding process.

[0064] During the molding process, the flange construction positioning lines / points of the web 21 can be marked on the upper surface of the support platform 12. Trapezoidal strips or screw posts are then connected to the support platform 12 via spot welding or other methods. Thermally conductive engineering plastic modules 130 are laid on the upper surface of the support platform 12 according to the size of the web 21, and fixedly connected to the support platform 12 using fasteners 122 or trapezoidal strips. Based on the shape and size of the web 21, lines are drawn on the edge of the thermally conductive engineering plastic modules 130, and then cut. Simultaneously, space is left for the silicone strip mold. Baffles are installed on the support platform 12 according to the flange positioning lines / points.

[0065] When reusing the old web 21, mark the flange positioning lines / points on the upper surface of the support platform 12. If the new web 21 is smaller than the old web 21, some of the thermally conductive engineering plastic modules 130 need to be removed beforehand according to the size of the web 21. Add or remove edge thermally conductive engineering plastic modules 130 according to the size of the web 21. Draw lines on the edge thermally conductive engineering plastic modules 130 according to the shape and size of the web 21, and then cut them. At the same time, leave space for the silicone strip mold. Install the baffle on the upper surface of the support platform 12 according to the flange positioning lines / points.

[0066] Due to the continuous updates in blade models, the dimensions of the corresponding web 21 also change significantly. The molding dies provided in some embodiments of this application can be adapted to the molding die requirements of new blade webs by adjusting the number and arrangement of the thermally conductive engineering plastic modules 130, and by adjusting the shape of the thermally conductive engineering plastic modules 130 at the edges. Each individual thermally conductive engineering plastic module 130 is small in size and lightweight, facilitating transportation and storage. Furthermore, the modules 130 are easy and quick to install and replace, requiring no sealing, which can significantly reduce installation costs. By adjusting the number and arrangement of the thermally conductive engineering plastic modules 130 to adapt to the different size requirements of the web 21, most of the thermally conductive engineering plastic modules 130 can be reused multiple times. This greatly reduces the development cost of new molds.

[0067] by Figure 6 and Figure 7 For example, when the product line is adjusted, the mold boss 13 only needs to adjust the number of modules 130 and rearrange the modules 130 to adapt to the new size. Among them, only the cut modules 130 located at the edge of the mold boss 13 cannot be reused, while most of the other modules 130 can be reused.

[0068] Those skilled in the art will understand that the above embodiments are specific implementations of this application, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this application.
