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 mold units spliced ​​within the forming area. The multiple mold units 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. At least some mold units have different projected areas on 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 mold units of different sizes assembled on a support platform to form a mold boss. The mold units can be connected to the support platform to form the mold boss, and mold units of different sizes can be connected at different positions on the support platform. By assembling multiple mold units, processing surfaces of different sizes can be formed to adapt to the forming of different webs, thereby improving the applicability of the forming mold. Furthermore, when adjusting the size of the mold boss, the mold units can be reused, thereby reducing the cost of the forming mold.

[0007] In some embodiments, the multiple mold units include a first mold unit and a second mold unit. The projected area of ​​the first mold unit on the support platform is larger than that of the second mold unit on the support platform, and the first mold unit is closer to the center of the molding area than the second mold unit. In this way, by setting the larger mold unit to correspond to the center area of ​​the molding area, it is easier to complete the splicing and combination of the mold units to form a mold boss corresponding to the web.

[0008] In some implementations, the projected area of ​​the first mold unit on the support platform is a geometric multiple of the projected area of ​​the second mold unit on the support platform. This allows for the easy assembly and splicing of mold units of different sizes and types, avoiding the appearance of seams, by ensuring that the dimensions of different mold units are geometrically proportional.

[0009] In some embodiments, the plurality of mold units further includes a third mold unit, the third mold unit having a smaller projected area on the support platform than the first mold unit on the support platform, and the third mold unit and the second mold unit abutting against the same first mold unit. This allows for the use of more than two types of mold units in a combined configuration, facilitating the shape fitting of the web at the edges of the molding area.

[0010] In some implementations, the projected area of ​​the third mold unit on the support platform is half that of the second mold unit on the support platform. This allows for the fitting and splicing of different sizes and shapes at the edges of the molding area by maintaining a close dimensional relationship between the two types of mold units.

[0011] In some embodiments, the projected area of ​​the third mold unit on the support platform is equal to the projected area of ​​the second mold unit on the support platform, and the projections of the third mold unit and the second mold unit on the support platform have different dimensions in multiple directions. This allows for the filling and covering of molding areas with different shape requirements by having mold units with equal projected areas but different projected dimensions.

[0012] In some embodiments, the plurality of mold units further includes a fourth mold unit, which abuts against one side of the same first mold unit. This allows for shape fitting at edges with gentler extensions by using mold units of the same size and type positioned at the edge of the molding area.

[0013] In some embodiments, each mold unit includes a cover plate and a plurality of tubular members sequentially arranged on the cover plate in the same direction, the tubular members being attached to a support platform. This allows the mold unit to be fabricated using a combination of the cover plate and the tubular members, facilitating mold unit fabrication and reducing manufacturing costs.

[0014] In some embodiments, the interior of each tubular component is filled with a thermally conductive material. This facilitates heat transfer by filling the interior of the tubular components with a thermally conductive material, which helps ensure the curing effect during web forming.

[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. In this way, the positioning member abuts against the edge of the mold boss, facilitating demolding after the web is formed. Attached Figure Description

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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] To improve mold adaptability and reduce mold costs, some embodiments of this application provide a forming mold for a blade web. In the forming mold for the blade web, multiple mold units of different sizes are spliced ​​together to form a mold platform, which can be used to form webs of different sizes. Modular units 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 spliced ​​mold units needs to be adjusted. For mold units near the baffle, they can be ground or cut to fit the shape of the web flange. Uncut mold units away from the baffle can be reused after the web size changes. This allows the mold to adapt to the forming of different webs, reduces waste of mold bosses, and lowers mold costs.

[0030] The following is combined with Figures 1 to 5 This application describes the structure of the forming mold for the blade web provided in some embodiments.

[0031] like Figures 1 to 5 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 mold units spliced ​​and arranged in the forming area. The multiple mold units 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. At least some of the mold units have different projected areas on 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.

[0032] 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.

[0033] The mold boss 13 provides a platform for material laying during the forming of the web 21. The mold boss 13 is formed by assembling mold units of multiple sizes. Different mold units abut against each other, forming a machining surface on the support platform 12 corresponding to the size of the web 21. The forming material for the web 21 can be laid on the machining surface for forming. The detachable connection between the mold unit and the support platform 12 can be achieved through spot welding or a detachable connection method. The projection shape of the mold unit on the support platform 12 can be polygonal, such as a triangle, rectangle, or square, or it can be trapezoidal.

[0034] 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.

[0035] The blade web forming mold provided in some embodiments of this application uses multiple mold units of different sizes to form a mold boss 13 on a support platform 12. The mold units can be connected to the support platform 12 to form the mold boss 13, and mold units of different sizes can be connected at different positions on the support platform 12. By splicing multiple mold units, 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 mold units can be reused, thereby reducing the cost of the forming mold.

[0036] In some embodiments, the plurality of mold units may include a first mold unit 131 and a second mold unit 132. The projected area of ​​the first mold unit 131 on the support platform 12 is greater than the projected area of ​​the second mold unit 132 on the support platform 12. The first mold unit 131 is closer to the center of the molding area than the second mold unit 132.

[0037] In other words, larger mold units are placed at the center of the molding area, while smaller mold units are placed near the edges of the baffle assembly. Larger mold units can be used to fill the central area of ​​the molding area, while smaller mold units can be used for fitting near the edges of the baffle assembly. By placing larger mold units in the center of the molding area, the mold boss 13 of the required shape and size can be quickly constructed.

[0038] In addition, the projected area of ​​the first mold unit 131 on the support platform 12 can be geometrically proportional to the projected area of ​​the second mold unit 132 on the support platform 12.

[0039] This means that mold units of different sizes can have corresponding dimensional relationships. For example, the projected area of ​​the first mold unit 131 on the support platform 12 can be two, three, or four times the projected area of ​​the second mold unit 132 on the support platform 12. When the projected shape of the mold unit on the support platform 12 is rectangular, the length of the first mold unit 131 can be designed to be multiple times the length of the second mold unit 132, and / or the width of the first mold unit 131 can be designed to be multiple times the width of the second mold unit 132.

[0040] When there is a geometric multiple relationship between the projected areas of mold units of different sizes, multiple second mold units 132 can be set to correspond to the same first mold unit 131. This is beneficial for partitioning the molding area, and for the mold bosses 13 with corresponding size relationships at the joints of the mold units.

[0041] In some embodiments, the plurality of mold units may further include a third mold unit 133, the projected area of ​​the third mold unit 133 on the support platform 12 is smaller than the projected area of ​​the first mold unit 131 on the support platform 12, and the third mold unit 133 and the second mold unit 132 abut against the same first mold unit 131.

[0042] The third mold unit 133 and the second mold unit 132 are both located adjacent to the first mold unit 131, and can be combined and spliced ​​by more than two mold units. This is beneficial for shape fitting near the edge of the forming area, that is, at the forming area corresponding to the flange of the web plate 21. It is also suitable for splicing and forming the mold boss 13 at the edge.

[0043] In some embodiments, the projected area of ​​the third mold unit 133 on the support platform 12 may be half the projected area of ​​the second mold unit 132 on the support platform 12.

[0044] In other words, the third mold unit 133 and the second mold unit 132 have a specific dimensional correspondence. The third mold unit 133 can abut against one side of the second mold unit 132, supplementing the molding area near the edge, so as to adapt to the molding shape of the gradually changing width of the web 21 itself.

[0045] In some embodiments, the projected area of ​​the third mold unit 133 on the support platform 12 may be equal to the projected area of ​​the second mold unit 132 on the support platform 12, and the projected area of ​​the third mold unit 133 on the support platform 12 and the projected area of ​​the second mold unit 132 on the support platform 12 may have different dimensions in multiple directions.

[0046] In other words, the third mold unit 133 can have the same projected area as the second mold unit 132. Simultaneously, the third mold unit 133 and the second mold unit 132 are designed with different dimensional relationships in the same direction. For example, when both the third mold unit 133 and the second mold unit 132 have rectangular projected shapes, the projected length of the third mold unit 133 can be controlled to be greater than the projected length of the second mold unit 132, while keeping their projected areas equal, and the projected width of the third mold unit 133 smaller than the projected width of the second mold unit 132. By making the third mold unit 133 and the second mold unit 132 have the same projected area but different projected dimensions in corresponding directions, it is beneficial to fit the forming shape of the web 21 in a forming area where the overall width dimension continuously changes. This allows mold units of different sizes to be spliced ​​together to create a mold boss 13 that is as consistent as possible with the shape of the web 21, thereby reducing material waste in the mold units and lowering the manufacturing cost of the forming mold.

[0047] In some embodiments, the plurality of mold units may further include a fourth mold unit 134, and the plurality of fourth mold units 134 abut against one side of the same first mold unit 131.

[0048] like Figure 2 As shown, at the edge of the molding area where the shape is relatively gentle, multiple fourth mold units 134 of the same size and type can be used to fill and cover it. This simplifies the splicing structure of the mold boss 13. At the same time, by abutting the fourth mold units 134 of the same size and type against one side of the first mold unit 131, dimensional consistency can be ensured and splicing gaps can be avoided.

[0049] like Figure 4 and Figure 5 As shown, each mold unit may include a cover plate 1301 and a plurality of tubular members 1302 arranged sequentially on the cover plate 1301 in the same direction, the plurality of tubular members 1302 being attached to the support platform 12.

[0050] Both the cover plate 1301 and the tubular component 1302 can be made of metal to improve the stability of the mold unit when placed on the support platform 12. Simultaneously, the good thermal conductivity of metal allows for rapid heat transfer from the heating unit 102 to the molding material of the web 21, which is beneficial for the curing effect of the web 21 during molding. In practice, the tubular component 1302 can be made of square tubing, with multiple square tubing welded together side-by-side, and then welded to the cover plate 1301 to form the mold unit. The mold unit can also be formed by enclosing different plate-like components to create an internally hollow structure, or by stacking plate-like components.

[0051] In addition, the interior of each tubular component 1302 may be filled with thermally conductive material.

[0052] The thermally conductive material filling the inside of the tubular component 1302 can expel air from inside the component, reducing thermal resistance. Simultaneously, the thermal conductivity of the material allows for rapid heat transfer, preventing heat loss. In practice, the thermally conductive material can be a metal filler, a plastic filler with low thermal resistance, or a liquid filler.

[0053] In some embodiments, the molding die may further include a first positioning member 16 and a second positioning member 17, wherein the first positioning member 16 abuts against one side of the mold boss 13 and the second positioning member 17 abuts against the other side of the mold boss 13.

[0054] 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.

[0055] 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 web 21 being produced changes, a new mold boss 13 shape can be formed simply by adjusting the arrangement of the mold units. At the same time, most of the previously used mold units can be reused, improving the utilization rate of the mold units and reducing mold costs.

[0056] The mold unit design can be achieved by meshing the mold bosses 13 of the required shape and size, with meshes of the same shape serving as the basic mold units for the mold bosses 13. Different shapes and sizes of meshes are divided at the center and edges of the mold bosses 13 to form mold units of different sizes. The mold unit can be constructed using a thin-walled hollow square tube with an upper thin plate. The inside of the square tube is filled with a lightweight thermally conductive material to improve thermal conductivity. The mold units and the support platform 12, as well as different mold units, can be fixed by spot welding; welding is simple and requires no sealing. Assembling the mold bosses 13 using meshed mold units solves the problem of conventional molding dies where the shape of the mold bosses 13 cannot be changed, leading to waste when switching blade shapes and making reuse impossible.

[0057] Using thin-walled square tubes allows for a rectangular shape in the basic mold unit, facilitating the assembly of different mold units. Filling the internal space of the square tube with a thermally conductive material, such as a mixture of epoxy resin and aluminum powder, effectively improves the thermal conductivity of the mold unit.

[0058] Due to the continuous updates in blade models, the dimensions of the corresponding web 21 have also changed significantly. This solution can adapt to the new web 21 mold requirements by adjusting the number and arrangement of basic units.

[0059] By increasing or decreasing the number and arrangement of mold units, the forming of web plates 21 with different heights and widths can be adapted. During the forming process of the web plate 21, the mold units can transfer the heat required for the manufacturing of the web plate 21, thus meeting the heat requirements during the forming process.

[0060] During the mold making process, the positioning lines / points for the flange structure of the web plate 21 mold can be marked on the upper plane of the support platform 12. Mold units of different sizes are laid on the upper plane of the support platform 12 according to the size of the web plate 21 and fixed to the support platform 12 by spot welding. According to the shape and size of the web plate 21, lines are drawn on the edge mold units and then cut. At the same time, space is left for the silicone strip mold. Baffles are installed on the support platform 12 according to the positioning lines / points.

[0061] When reusing the mold, mark the positioning lines / points for the flange structure of the new web plate 21 mold on the upper surface of the support platform 12. If the new web plate 21 is smaller than the old web plate 21, some mold units need to be removed in advance according to the size of the web plate 21. In practice, mold units can be added or removed according to the size of the web plate 21. Draw lines on the mold units at the edge according to the shape and size of the web plate 21, and then cut them. At the same time, leave the space required for the silicone strip mold. Install the baffle on the upper surface of the support platform 12 according to the positioning lines / points.

[0062] Due to the continuous updates in blade models, the dimensions of the corresponding web 21 also change significantly. The forming molds provided in some embodiments of this application can be adapted to the forming mold requirements of new blade webs by adjusting the number and arrangement of mold units of different sizes and the shape of the mold units at the edges. Most mold units can be reused multiple times, thus greatly reducing the development cost of new molds. The production of mold units of various sizes is convenient and fast; individual mold units are small in size and light in weight, facilitating transportation and storage. Mold units are easy and quick to install and replace, with low requirements for welding processes and no sealing requirements, which can greatly reduce welding costs. The construction of square tubes and thin plates controls the weight of the overall structure while providing excellent rigidity. In practice, mold units can be up to two meters long and 400 centimeters wide. Furthermore, the length and width of the mold units can be varied to form mold units of different sizes.

[0063] by Figure 2 and Figure 3 For example, when the product line is adjusted, the mold boss 13 only needs to adjust the number of mold units and rearrange the mold units to adapt to the new size. Only the cut mold units located at the edge of the mold boss 13 cannot be reused, while most other mold units can be reused.

[0064] 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.
